Start here: why this chapter matters
In simple wordsA household budget lists what comes in (salary, rent, interest) and what goes out (food, school fees, a new fridge, loan repayments). If it spends more than it earns, it borrows. The government's budget is the same idea on a national scale — except that its spending and taxes also change everyone else's income and jobs, and its borrowing can last for generations.
Every February the Union Budget dominates the news: fiscal deficit targets, tax changes, capital spending, subsidies, borrowing. This chapter gives the vocabulary and the logic. UPSC tests it heavily — the difference between revenue and capital items, the three deficits (often with numbers), FRBM, GST, crowding out, and Mains questions on capital vs revenue budgets, tax expenditure, gender budgeting, subsidies and public expenditure management.
- Builds on: Chapter 1 (the State and public goals), Chapter 2 (personal disposable income, indirect taxes and subsidies in national income), Chapter 3 (borrowing from the RBI, SLR, government securities) and Chapter 4 (the multiplier — now with G and T).
- Leads into: Chapter 6 (twin deficits: budget and current account).
- Indian Economic Development: Chapter 3 (1991 fiscal crisis, tax reform, GST, disinvestment); Chapter 5 (subsidies and rural spending).
- Polity (Class 11–12): Parliament's control over the budget, money bills, the Consolidated Fund and the Finance Commission are in the polity chapters (Indian Constitution at Work — Legislature; Federalism). This chapter is the economics of the budget.
- UPSC: GS3 ‘government budgeting’, ‘mobilisation of resources’, ‘effects of liberalisation on the economy’; Prelims economy almost every year.
| Word | What it means here |
|---|---|
| Annual Financial Statement | The budget document required by Article 112 — estimated receipts and expenditure for the year |
| Public good | Non-rival and non-excludable — e.g. defence, clean air |
| Revenue receipt | Receipt creating no liability and no reduction of assets: taxes, non-tax revenue |
| Capital receipt | Receipt that creates a liability (borrowing) or reduces assets (disinvestment, loan recovery) |
| Revenue / capital expenditure | Spending that creates no asset / that creates assets or reduces liabilities |
| Fiscal deficit | Total expenditure − (revenue receipts + non-debt capital receipts) = total borrowing need |
| Primary deficit | Fiscal deficit − interest payments |
| Lump-sum / proportional tax | Fixed amount regardless of income / fixed share t of income |
| Automatic stabiliser | A feature (income tax, welfare payments) that dampens fluctuations without new decisions |
| Discretionary fiscal policy | Deliberate changes in spending or tax rates |
| Ricardian equivalence | The view that debt and taxes have the same effect, since people save for future taxes |
| Crowding out | Government borrowing absorbing savings and raising interest rates, reducing private investment |
Reading the chapter-opening illustration (page 66)A road roller flattening a road while a worker shovels material — public works. The point: roads are a classic public good paid for through the budget (and building them is capital expenditure).
At a glance — the six ideas to carry away
- Budget = Annual Financial Statement (Article 112), 1 April–31 March; revenue and capital accounts.
- Functions: allocation (public goods: non-rival, non-excludable), redistribution, stabilisation.
- Revenue deficit = RE − RR; fiscal deficit = TE − (RR + non-debt capital receipts) = borrowing; primary = FD − interest.
- NCERT Table 5.1 (Centre, 2024–25 P.A.): RD 2.6%, FD 5.6%, PD 2.0% of GDP; interest 3.6%.
- Multipliers (c = 0.8): spending 5, tax −4, transfers 4, balanced budget 1; proportional tax shrinks them (automatic stabiliser).
- FRBM Act 2003 (FD 3%, end revenue deficit); GST from 1 July 2017 (101st Amendment, 2016) — a tax on value added.
1. What the budget is for: allocation, redistribution, stabilisation
In simple wordsIf a private company built a lighthouse, it could not stop passing ships from using its light, so no one would pay — and it would not be built. Some things only get done if everyone pays through taxes. That is why governments provide them.
Allocation: the government provides goods the market will not — national defence, roads, administration — called public goods. They differ from private goods in two ways: they are non-rival (one person's use does not reduce another's — a park, cleaner air) and non-excludable (non-payers cannot be kept out). Non-payers are free-riders; since the link between paying and using breaks, the government must step in. Public provision (financed by the budget, used without direct payment) is different from public production (made by the government itself).
Redistribution: through taxes and transfers the government changes households' personal disposable income towards a distribution society considers fair — e.g. progressive income tax (higher rate on higher incomes). Stabilisation: when demand is too low for full employment (wages and prices do not fall far enough to restore it), the government raises demand; when demand outruns output and causes inflation, it restrains demand.
Beyond NCERT
- UPSC 1996: redistribution is best achieved through progressive taxation combined with progressive expenditure (spending that benefits the poor more).
- Merit goods (education, health) are rival and excludable but under-consumed if left to the market — another reason for public provision.
2. Receipts and expenditure: revenue versus capital
In simple wordsYour salary is a revenue receipt — you owe nothing for it. A bank loan or selling your scooter is a capital receipt — you either owe money now or have one asset less. Paying the electricity bill is revenue spending; buying a house is capital spending. The government's accounts follow the same logic.
Revenue receipts do not create a claim on the government — they are non-redeemable. Tax revenue: direct taxes (personal income tax, corporation tax; wealth, gift and estate duties brought little and were called ‘paper taxes’) and indirect taxes (excise, customs, service tax — most now replaced by GST). Firms are taxed proportionally; excise taxes spare necessities and tax luxuries, tobacco and petroleum heavily. Non-tax revenue: interest on government loans, dividends and profits, fees, and cash grants-in-aid from abroad.
Capital receipts either create a liability (fresh loans, to be repaid with interest) or reduce financial assets (sale of PSU shares — disinvestment; recovery of loans). They are debt-creating (borrowing) or non-debt creating (recoveries, disinvestment).
Revenue expenditure creates no physical or financial asset: running government departments, salaries, pensions, interest payments (the single largest item), defence (committed), subsidies, and grants to States (even if States use them for assets). Capital expenditure creates assets or reduces liabilities: land, buildings, machinery, equipment, shares, and loans and advances to States, UTs and PSUs.
| Item | Revenue or capital? | Why |
|---|---|---|
| Income tax, GST, customs | Revenue receipt | No liability, no asset sold |
| Dividend from a PSU, interest received | Revenue receipt (non-tax) | Return on assets, asset kept |
| Market borrowing, loan from abroad | Capital receipt (debt-creating) | Creates a liability |
| Disinvestment, recovery of loans | Capital receipt (non-debt) | Reduces assets |
| Salaries, pensions, interest paid, subsidies | Revenue expenditure | No asset created |
| Grant to a State to build schools | Revenue expenditure (for the Centre) | Asset belongs to the State, not the Centre |
| Building a highway, loan to a State, buying shares | Capital expenditure | Asset created or claim acquired |
| Repaying a loan | Capital expenditure | Reduces a liability |
Reading Chart 1 — The Components of the Government Budget (page 69)A tree: the budget splits into revenue and capital budgets; the revenue budget into revenue receipts (tax and non-tax) and revenue expenditure (plan and non-plan); the capital budget into capital receipts and capital expenditure (plan and non-plan). The point: every rupee is classified twice — receipt or expenditure, and revenue or capital. Dated: the plan/non-plan split was removed from the Union Budget from 2017–18 † (Table 5.1's plan/non-plan rows are blank).
Beyond NCERT
- UPSC 2016: the capital budget includes asset acquisition, loans received from foreign governments, and loans to States — all three. UPSC 2025: capital receipts create a liability or reduce assets; borrowing and disinvestment are capital receipts; interest received is a revenue receipt, not a liability.
- Older UPSC questions (1992, 1995, 1997, 2014) asked what counted as non-plan expenditure (interest, defence, subsidies, salaries and pensions, maintenance) — learn it as history.
- Tax classification: corporation tax, wealth tax, fringe-benefit tax, interest tax and securities transaction tax are direct; customs, excise, service tax and GST are indirect (UPSC 2001, 2006, 2009). An ad valorem duty is a percentage of the price, as against a specific duty per unit (UPSC 1988).
- Tax expenditure (Mains 2013): revenue forgone through exemptions and deductions (e.g. housing-loan interest deductions) — spending through the tax code, reported in the budget's statement of revenue forgone.
- Since 2017 the Union Budget is presented on 1 February and the railway budget is merged into it †.
Exam traps
- Disinvestment is a capital receipt (non-debt creating), not revenue.
- Interest paid is revenue expenditure; loan repayment is capital expenditure.
- Grants to States are revenue expenditure for the Centre even if they build assets.
3. The deficits: revenue, fiscal and primary
In simple wordsIf you borrow to buy a sewing machine that earns money, the debt may pay for itself. If you borrow to pay the grocery bill, you will be poorer next year. Revenue deficit measures the second kind of borrowing; fiscal deficit measures all borrowing; primary deficit asks how much you would need to borrow if you had no old loans to pay interest on.
A budget is balanced if expenditure equals revenue, in surplus if revenue exceeds it, and in deficit if expenditure exceeds it — the usual case.
- Revenue deficit = revenue expenditure − revenue receipts. The government is dissaving, using other sectors' savings for its consumption; it must borrow even for current needs, piling up debt and interest, and is often forced to cut productive capital or welfare spending later.
- Gross fiscal deficit = total expenditure − (revenue receipts + non-debt creating capital receipts) = the government's total borrowing requirement. From the financing side: net borrowing at home + borrowing from the RBI + borrowing from abroad (home borrowing includes small savings and banks' SLR holdings). Also: FD = RD + capital expenditure − non-debt capital receipts; a large share of RD in FD means borrowing goes into consumption.
- Gross primary deficit = gross fiscal deficit − net interest liabilities (interest paid − interest received on net domestic lending): it shows the current fiscal imbalance, excluding the legacy of past debt.
Reading Table 5.1 — Receipts and expenditures of the central government, 2024–25 P.A. (page 71)
- % of GDP: revenue receipts 9.2 (tax net of States' share 7.9, non-tax 1.4); revenue expenditure 11.8 (interest 3.6, major subsidies 1.4, defence 1.0); revenue deficit 2.6 (11.8 − 9.2 ✓); capital receipts 5.8 (loan recovery 0.1 + disinvestment 0.1 + borrowing 5.6 ✓); capital expenditure 3.2; non-debt receipts 9.4 (9.2 + 0.1 + 0.1 ✓); fiscal deficit 5.6; primary deficit 2.0 (5.6 − 3.6 ✓).
- Slip: total expenditure is printed 1.5; it is 11.8 + 3.2 = 15.0. Check: 15.0 − 9.4 = 5.6 ✓.
- Slip in the text (page 72): ‘non-debt creating capital receipts equals 9.4 per cent of GDP’ — 9.4 is all non-debt receipts (revenue receipts + 0.2); non-debt capital receipts are only 0.2.
- 7.9 + 1.4 = 9.3 against 9.2 printed — rounding.
- The table computes primary deficit as FD − gross interest; the text's definition uses net interest liabilities. With interest receipts small, the difference is minor.
- These are NCERT's figures for one year; deficits change every year — quote them as ‘2024–25 (provisional), per NCERT’.
⤵ Why a revenue deficit worries economists (NCERT's argument)
Revenue expenditure > revenue receiptsgovernment dissaves — borrows to pay salaries, interest, subsidies
Debt and interest pile upinterest is itself revenue expenditure → bigger revenue deficit next year
Committed spending cannot be cutinterest, salaries, pensions, defence
So capital and welfare spending get cutlower growth and adverse welfare effects
Worked examples (UPSC 2025). (1) Fiscal deficit ₹50,000 crore, interest ₹1,500 crore → primary deficit = 50,000 − 1,500 = ₹48,500 crore (non-debt receipts of ₹10,000 crore are already inside the fiscal deficit — a distractor). (2) Revenue expenditure ₹80,000, revenue receipts ₹60,000, borrowings ₹10,000, interest ₹6,000 crore → revenue deficit = ₹20,000; fiscal deficit = borrowing = ₹10,000; primary deficit = 10,000 − 6,000 = ₹4,000. All three statements hold (see the answer-key note in the strategy section).
Beyond NCERT
- NCERT's footnote: the old ‘budget deficit’ (total expenditure − total receipts including borrowing, essentially the gap financed by short-term treasury bills and RBI credit) was discontinued from 1997–98. Older UPSC questions use it: fiscal deficit is larger than budgetary deficit and = budgetary deficit + net borrowing (1994, 1999); the 2001 matching question pairs fiscal deficit with ‘total expenditure over total receipts less borrowings’.
- Deficit financing, in Indian usage, meant covering the deficit by borrowing from the RBI — effectively creating new money — historically used for development spending (UPSC 1987, 1992, 2013). It is the most inflationary way to finance a deficit (UPSC 2013, 2021). The FRBM Act ended RBI's subscription to primary issues of government securities from 2006–07.
- Monetised deficit: the part of the deficit financed by the RBI.
Exam traps
- Fiscal deficit = borrowing, not the gap between revenue expenditure and revenue receipts.
- Primary deficit removes interest, not capital expenditure.
- A zero primary deficit means current borrowing covers only interest on past debt.
- Non-debt capital receipts reduce the fiscal deficit; borrowings do not.
4. Fiscal policy and the multipliers (Box 5.1)
In simple wordsIf the government spends ₹100 on a road, the full ₹100 is new demand. If it instead cuts your taxes by ₹100, you spend perhaps ₹80 and save ₹20 — so the first push is smaller. That is why spending moves the economy more than an equal tax cut.
Keynes argued fiscal policy should stabilise output and employment. With lump-sum taxes T and transfers TR: C = C̄ + c(Y − T + TR) (5.1); AD = C̄ + c(Y − T + TR) + I + G (5.2); equilibrium Y* = [C̄ − cT + cTR + I + G] ÷ (1 − c) (5.4). Taxes shift the consumption and AD lines down in parallel; G shifts AD up.
- Government spending multiplier ΔY/ΔG = 1 ÷ (1 − c) (5.6).
- Tax multiplier ΔY/ΔT = −c ÷ (1 − c) (5.8) — negative, and smaller in size, because taxes act only through disposable income.
- Balanced-budget multiplier (ΔG = ΔT) = 1 ÷ (1 − c) − c ÷ (1 − c) = 1 (5.9).
- Transfers multiplier ΔY/ΔTR = c ÷ (1 − c) (5.22) — like a negative tax.
- With proportional tax T = tY: the MPC out of income falls to c(1 − t), AD becomes flatter, and the multiplier falls to 1 ÷ [1 − c(1 − t)] (5.18).
NCERT's examples. 5.1 (c = 0.8): spending multiplier 5 → ΔG = 100 raises Y by 500; tax multiplier −4 → a tax cut of 100 raises Y by 400; raising G and T by 100 each raises Y by 500 − 400 = 100. 5.2 (t = 0.25): c(1 − t) = 0.8 × 0.75 = 0.6 → multiplier 1 ÷ 0.4 = 2.5; ΔG = 100 → ΔY = 250. 5.3 (c = 0.75): ΔG = 20 → ΔY = 4 × 20 = 80; ΔTR = 20 → ΔY = 3 × 20 = 60. All checked.
Reading Figs. 5.1–5.5 (pages 74–76)
- Fig. 5.1: higher government expenditure shifts AD up in parallel (C̄ + I + G′ − cT); equilibrium moves from Y* to Y′.
- Fig. 5.2: a tax cut (T to T′) shifts AD up by c times the cut — a smaller shift than an equal rise in G.
- Fig. 5.3: proportional taxes make AD flatter (slope c(1 − t) instead of c); Fig. 5.4: a rise in G with proportional taxes raises income by less; Fig. 5.5: a cut in the tax rate (t to t′) makes AD steeper, like a higher propensity to consume.
- The point: the size of a fiscal push depends on what is changed (spending, taxes, transfers) and on the tax structure.
Reading the cartoons ‘How does the Fiscal Policy try to achieve its basic objectives?’ (page 73) and ‘Why is the poor man crying?’ (page 75)
- A man labelled Fiscal Policy leans against a cube whose faces read Growth, Equity and Stability — the three goals map onto allocation, redistribution and stabilisation.
- A poor man with a sack trudges up a staircase labelled Taxes, weeping. The prompt asks why he cries and how to wipe his tears: indirect taxes (and rising ones) fall heavily on the poor relative to income; remedies include progressive direct taxes, exemptions or low rates on necessities, and targeted transfers.
Automatic stabilisers: a proportional income tax makes disposable income — and consumption — less sensitive to GDP: in booms part of extra income is taxed away; in slumps tax payments fall and consumption falls less. Welfare transfers do the same; firms smoothing dividends and households protecting living standards add private stabilisers. They cut only part of a fluctuation; discretionary policy — e.g. raising G from G₀ to G₁ when investment falls from I₀ to I₁ so that autonomous spending is unchanged — must do the rest.
Exam traps
- Tax multiplier is one less in absolute value than the spending multiplier (lump-sum case): 5 vs −4.
- Balanced-budget multiplier is 1, not 0.
- Proportional taxes reduce the multiplier; they do not shift it to zero.
- A larger deficit is not always a more expansionary policy: in a recession tax revenue falls automatically, so the deficit widens even with unchanged policy.
5. Government debt: is it a burden? (a debate)
In simple wordsA family that borrows for a wedding feast is poorer later; one that borrows to send a child to engineering college may be richer. Whether government debt is a burden likewise depends on what it buys, who holds it, and whether the economy grows faster than the interest bill.
Deficits must be financed by taxes, borrowing or printing money; governments mostly borrow, creating debt. A deficit is a flow that adds to the stock of debt; interest on the debt itself adds to future deficits. A government is unlike a single trader: it can tax and print money, so ‘the whole’ must be treated differently from ‘the part’.
⤵ Two views on borrowing to cut taxes
Government cuts taxes, borrows the differencedeficit rises; debt will need future taxes
Traditional viewshort-sighted (or selfish) consumers feel richer and spend more → demand rises; future generations bear higher taxes; national saving falls
Ricardian equivalence (after David Ricardo)forward-looking families foresee future taxes for their children → save the tax cut → national saving and demand unchanged
Evidence is mixedliquidity-constrained or short-horizon households tend to spend tax cuts, so full equivalence rarely holds †
| Argument | Debt is a burden because… | …but |
|---|---|---|
| Future generations | Bonds repaid later by taxes on young workers lower their consumption | If the money funds infrastructure earning more than the interest rate, future generations gain |
| Crowding out | Government bonds compete with private borrowers for savings; interest rates rise; private investment falls (UPSC 2026) | Savings are not fixed: if deficits raise output, income and saving rise too |
| ‘We owe it to ourselves’ | — | Internal debt only transfers resources between citizens; external debt is a real burden (goods must be sent abroad to pay interest) |
| Inflation | Extra demand at full capacity raises prices | With unused capacity, deficits raise output, not prices |
| Sustainability | Debt growing faster than GDP is unsustainable | Judge debt relative to GDP: growth can ‘pay off’ debt |
Beyond NCERT
- Internal debt includes market borrowings (dated securities), treasury bills and special securities issued to the RBI (UPSC 2001, all three); dated securities sold at market-related rates are its largest part, and a share of households' financial savings ends up financing government borrowing (UPSC 2022, both true). The government-securities market is the ‘gilt-edged’ market (UPSC 2000).
- The RBI manages the debt of the Centre and the States; treasury bills are issued only by the Centre and at a discount to face value (UPSC 2018).
- Debt dynamics (a rule of thumb): the debt-to-GDP ratio stabilises when nominal GDP growth exceeds the interest rate on debt and the primary deficit is small.
- Article 293(3): a State that owes money to the Centre needs the Centre's consent to borrow (part of UPSC 2018's FRBM question).
6. Reducing deficits, and the FRBM Act (Box 5.2)
In simple wordsA family that keeps overspending may write itself a rule: ‘We will never borrow more than 10% of our income.’ Rules help resist the temptation to spend now and pay later. The FRBM Act is such a rule for the Union government — though, like family rules, it has been bent when emergencies arrive.
Deficits can be cut by raising taxes or cutting spending. India has tried to raise tax revenue with more reliance on direct taxes (indirect taxes are regressive — they take a larger share of a poor person's income), and to raise money by selling PSU shares. The main thrust has been cutting spending — better planning and administration, and reconsidering the scope of government. A Planning Commission evaluation found the government spent ₹3.65 to deliver ₹1 of food subsidy to the poor, suggesting cash transfers could raise welfare. But cutting spending on agriculture, education, health and poverty alleviation would hurt the economy.
Reading Box 5.2 — Fiscal Responsibility and Budget Management Act, 2003 (pages 78–79)
- Enacted August 2003; rules effective July 2004. Aim: inter-generational equity, long-run stability, removing fiscal obstacles to monetary policy.
- Main features: cut the fiscal deficit to 3% of GDP and eliminate the revenue deficit (by March 2009 after a one-year rescheduling; originally 2008); annual cuts of 0.3% (FD) and 0.5% (RD) of GDP; deviations only for national security, calamity or exceptional grounds; no borrowing from the RBI except temporary advances; the RBI not to subscribe to primary issues of government securities from 2006–07; transparency; three statements with the budget (Medium-term Fiscal Policy, Fiscal Policy Strategy, Macroeconomic Framework); quarterly reviews to Parliament.
- Applies to the Centre; 26 States had their own fiscal responsibility laws (NCERT's count). Critics feared welfare spending would be cut to meet targets.
- A FRBM Review Committee was set up to revamp the framework.
- Dated wording: ‘in the last thirteen years’ dates this paragraph to about 2016.
Beyond NCERT — after 2003 (stated only where certain)
- The FRBM Review Committee (chaired by N.K. Singh, 2017) recommended using debt as the main anchor — general government debt of 60% of GDP (Centre 40%, States 20%) — with the fiscal deficit as the operating target (UPSC 2018).
- A 2018 amendment (through the Finance Act) adopted debt as an anchor, with an escape clause for exceptional circumstances. The Covid shock of 2020–21 pushed deficits far above the 3% target; the Union Budget for 2021–22 set a glide path to bring the fiscal deficit below 4.5% of GDP by 2025–26. For targets beyond that, read the latest Budget's FRBM statements — they have been revised more than once.
- UPSC 2006: FRBMA concerns both fiscal and revenue deficits; UPSC 2010: it did not require eliminating the primary deficit; UPSC 2020: the Macroeconomic Framework Statement is mandated by the FRBM Act, not the Constitution.
- Gender budgeting (NCERT footnote): a gender budget statement since 2005–06, enlarged in 2006–07 (Mains 2016).
- Direct Benefit Transfer of subsidies into bank accounts (Mains 2015) is the policy response to leakages like the ₹3.65-per-rupee finding; critics cite exclusion errors and the need for bank access.
Fiscal rules: both sides
- For rules: politicians face pressure to spend before elections; binding rules protect future generations, keep interest costs and inflation in check, and leave room for monetary policy.
- Against rigid rules: they can force cuts in capital and welfare spending in slumps (when stimulus is needed), encourage creative accounting, and many advanced economies moved away from rigid numerical targets. NCERT notes this tension in Box 5.2.
- A balanced position: rules with escape clauses and a medium-term anchor (debt) rather than a rigid annual number.
7. GST: one nation, one tax, one market (Box 5.3)
In simple wordsBefore GST, a shirt was taxed when the cloth was made, again when the shirt was made — including tax on the tax already in the cloth's price — and again by each State it passed through. GST taxes only the value each business adds, gives credit for tax already paid, and uses one set of rules for the whole country.
GST, operational from 1 July 2017, is a comprehensive destination-based tax on the supply of goods and services, with input tax credit along the supply chain — effectively a tax on value added at each stage, ending the cascading (tax on tax) of the old system. It subsumed Central taxes (central excise, service tax, central sales tax, some cesses) and State taxes (VAT/sales tax, entry tax, octroi, luxury and entertainment taxes, and others). Five petroleum products are outside GST for now; States still levy VAT on alcoholic liquor; tobacco attracts both GST and central excise.
⤵ How input tax credit works
Maker sells for ₹100 + 10% GSTpays ₹10 to government; buyer's invoice shows ₹10 tax
Trader sells for ₹150 + 10% GSTcollects ₹15, claims credit for the ₹10 already paid
Trader pays only ₹5= 10% of the ₹50 value it added
Total tax ₹15 = 10% of final valueno tax on tax; the consumer bears the whole of it
Reading Box 5.3 — GST (pages 79–80)
- Constitutional basis: the 101st Constitution Amendment Act (Presidential assent 8 September 2016) inserted Article 246A, giving Parliament and State legislatures concurrent power to tax goods and services; then the CGST, UTGST and SGST Acts. Rolled out at a special midnight session of Parliament, 30 June/1 July 2017.
- Claimed benefits: simpler taxes, a common national market, lower business costs and cascading, more competitive exports, a wider tax base, online compliance (gst.gov.in), less taxpayer–officer contact. ‘GDP is expected to rise by about 2%’ was a projection, not a measured result.
- Dated: the six rates (0, 3, 5, 12, 18, 28%) — the GST Council rationalised the slab structure in 2025 †; check the current schedule.
Beyond NCERT
- The GST Council (Article 279A) — the Union Finance Minister and State finance ministers — recommends rates and rules.
- UPSC 2017: GST's advantage is replacing multiple taxes and creating a single market — not reducing the current account deficit. UPSC 2011: VAT is a multi-point, destination-based tax on value added, borne by the final consumer — and it was not ‘basically a Central subject’ (it was a State tax).
- Debates: compliance burden on small firms, rate complexity, States' loss of fiscal autonomy and the end of GST compensation, and petroleum's exclusion.
Exam traps
- GST amendment 2016 (101st), rollout 1 July 2017.
- GST is destination-based (accrues where consumed), not origin-based.
- Petroleum products and alcoholic liquor are outside GST (as NCERT states).
NCERT exercise — answer outlines and worked numericals
Try each question yourself first. Questions 5–9 are numericals, worked in full. In Q5 and Q6 NCERT writes consumption as a function of Y; the standard solution (and the logic of Box 5.1) uses disposable income — we show that and note the alternative.
1. Explain why public goods must be provided by the government.
Public goods are non-rival (one person's use does not reduce others') and non-excludable (non-payers cannot be kept out). Users can free-ride, so voluntary payment fails and private firms will not supply them; the link between payment and use breaks. Hence the government provides them, financed by taxes (public provision), though production may be private. Examples: defence, street lighting, pollution control, parks.
2. Distinguish between revenue expenditure and capital expenditure.
Revenue: creates no physical or financial asset — salaries, pensions, interest, subsidies, grants to States, running costs. Capital: creates assets or reduces liabilities — land, buildings, machinery, roads, shares in PSUs, loans to States and PSUs, loan repayment. Revenue spending recurs; capital spending raises future capacity.
3. ‘The fiscal deficit gives the borrowing requirement of the government’. Elucidate.
FD = total expenditure − (revenue receipts + non-debt capital receipts). Whatever spending is not covered by revenue and non-debt receipts must be borrowed: FD = net borrowing at home + borrowing from the RBI + borrowing from abroad. Table 5.1: FD 5.6% of GDP = borrowings and other liabilities 5.6% ✓.
4. Give the relationship between the revenue deficit and the fiscal deficit.
FD = RD + capital expenditure − non-debt capital receipts. Table 5.1: 2.6 + 3.2 − 0.2 = 5.6. The share of RD in FD shows how much borrowing finances consumption rather than investment — a high share signals poor quality of spending.
5. I = 200, G = 150, net taxes = 100, C = 100 + 0.75Y. (a) Equilibrium income? (b) Government expenditure and tax multipliers? (c) If G rises by 200, change in equilibrium income?
Using disposable income (C = 100 + 0.75(Y − 100)):
(a) Y = 100 + 0.75Y − 75 + 200 + 150 = 375 + 0.75Y → 0.25Y = 375 → Y = 1,500.
(b) Spending multiplier = 1 ÷ 0.25 = 4; tax multiplier = −0.75 ÷ 0.25 = −3.
(c) ΔY = 4 × 200 = 800 (Y = 2,300).
If C is read literally as 100 + 0.75Y (taxes ignored): Y = 450 ÷ 0.25 = 1,800; multipliers and (c) unchanged.
(a) Y = 100 + 0.75Y − 75 + 200 + 150 = 375 + 0.75Y → 0.25Y = 375 → Y = 1,500.
(b) Spending multiplier = 1 ÷ 0.25 = 4; tax multiplier = −0.75 ÷ 0.25 = −3.
(c) ΔY = 4 × 200 = 800 (Y = 2,300).
If C is read literally as 100 + 0.75Y (taxes ignored): Y = 450 ÷ 0.25 = 1,800; multipliers and (c) unchanged.
6. C = 20 + 0.80Y, I = 30, G = 50, TR = 100. (a) Equilibrium income and multiplier? (b) G up by 30 — impact? (c) Lump-sum tax of 30 added to pay for it — how does income change?
Using disposable income Y + TR:
(a) Y = 20 + 0.8(Y + 100) + 30 + 50 = 180 + 0.8Y → Y = 900; multiplier = 1 ÷ 0.2 = 5.
(b) ΔY = 5 × 30 = 150 → Y = 1,050.
(c) Tax multiplier = −0.8 ÷ 0.2 = −4 → ΔY = −120 → Y = 930: net rise 30 = ΔG (balanced-budget multiplier 1).
If TR is ignored: Y = 100 ÷ 0.2 = 500, then 650 and 530.
(a) Y = 20 + 0.8(Y + 100) + 30 + 50 = 180 + 0.8Y → Y = 900; multiplier = 1 ÷ 0.2 = 5.
(b) ΔY = 5 × 30 = 150 → Y = 1,050.
(c) Tax multiplier = −0.8 ÷ 0.2 = −4 → ΔY = −120 → Y = 930: net rise 30 = ΔG (balanced-budget multiplier 1).
If TR is ignored: Y = 100 ÷ 0.2 = 500, then 650 and 530.
7. In the above question, calculate the effect on output of a 10 per cent increase in transfers, and a 10 per cent increase in lump-sum taxes. Compare.
Transfers 100 → 110 (ΔTR = 10): ΔY = c ÷ (1 − c) × 10 = 4 × 10 = +40.
Lump-sum taxes 30 → 33 (ΔT = 3): ΔY = −4 × 3 = −12.
Same multiplier size (4) with opposite signs; the transfer effect is larger here only because the base (100) is larger than the tax base (30).
Lump-sum taxes 30 → 33 (ΔT = 3): ΔY = −4 × 3 = −12.
Same multiplier size (4) with opposite signs; the transfer effect is larger here only because the base (100) is larger than the tax base (30).
8. C = 70 + 0.70YD, I = 90, G = 100, T = 0.10Y. (a) Equilibrium income? (b) Tax revenue at equilibrium? Balanced budget?
(a) Y = 70 + 0.7(0.9Y) + 90 + 100 = 260 + 0.63Y → 0.37Y = 260 → Y ≈ 702.7.
(b) T = 0.1 × 702.7 ≈ 70.3; G = 100 → deficit ≈ 29.7: the budget is not balanced.
(b) T = 0.1 × 702.7 ≈ 70.3; G = 100 → deficit ≈ 29.7: the budget is not balanced.
9. MPC 0.75 and 20% proportional income tax. Change in equilibrium income for (a) government purchases +20, (b) transfers −20.
c(1 − t) = 0.75 × 0.8 = 0.6; multiplier = 1 ÷ 0.4 = 2.5.
(a) ΔY = 2.5 × 20 = +50.
(b) Transfers multiplier = c ÷ [1 − c(1 − t)] = 0.75 ÷ 0.4 = 1.875 → ΔY = 1.875 × (−20) = −37.5 (assuming transfers are not taxed).
(a) ΔY = 2.5 × 20 = +50.
(b) Transfers multiplier = c ÷ [1 − c(1 − t)] = 0.75 ÷ 0.4 = 1.875 → ΔY = 1.875 × (−20) = −37.5 (assuming transfers are not taxed).
10. Explain why the tax multiplier is smaller in absolute value than the government expenditure multiplier.
A rise in G adds to demand in full at once (first round ΔG). A tax change affects demand only through disposable income: a tax cut of ΔT raises consumption by cΔT in the first round, as part is saved. So ΔY = ΔG(1 + c + c² + …) vs −ΔT(c + c² + …): 1 ÷ (1 − c) vs −c ÷ (1 − c). With c = 0.8: 5 vs −4.
11. Explain the relation between government deficit and government debt.
The deficit is a flow (per year); debt is a stock. Each year's fiscal deficit is financed by borrowing and adds to debt; debt raises interest payments, which add to future deficits — a possible snowball. Debt is judged relative to GDP: if output grows faster than debt (and interest), the ratio can fall.
12. Does public debt impose a burden? Explain.
Yes, if: it is repaid by taxing future generations; it crowds out private investment; it is owed abroad; it finances consumption rather than productive assets. Not necessarily, if: it is internal (‘we owe it to ourselves’), funds infrastructure with returns above the interest rate, or raises output and saving when resources are idle; Ricardian equivalence argues it has the same effect as taxes. Conclude: burden depends on use, holder and growth.
13. Are fiscal deficits inflationary?
Can be: higher spending or tax cuts raise demand; at full capacity prices rise — especially if financed by the RBI (money creation). Need not be: with unused capacity, higher demand raises output, not prices; financing by borrowing from the public is less inflationary than printing money.
14. Discuss the issue of deficit reduction.
Means: raise taxes (more direct, progressive taxation; wider base; GST), cut wasteful spending (subsidy targeting, DBT — NCERT's ₹3.65 per ₹1 example), disinvestment, better administration. Cautions: don't cut capital or social spending in agriculture, education, health; deficits widen automatically in recessions; rules like FRBM help but need flexibility.
15. What do you understand by G.S.T? How good is the system of G.S.T as compared to the old tax system? State its categories.
GST: a destination-based tax on supply of goods and services with input tax credit, from 1 July 2017. Better than the old system: ends cascading, one national market, fewer taxes and checkposts, online compliance, wider base. Categories: CGST and SGST (or UTGST) on supplies within a State; IGST on inter-State supplies and imports. Rate slabs as listed by NCERT have since been rationalised (2025) — check current rates. Concerns: compliance for small firms, petroleum outside, Centre–State revenue sharing.

One-liners
- Public goods: non-rival + non-excludable → free-riders → budget.
- Capital receipts create liabilities or reduce assets.
- Revenue deficit = RE − RR.
- Fiscal deficit = TE − (RR + non-debt capital receipts) = borrowing.
- Primary deficit = FD − interest.
- FD = RD + capital expenditure − non-debt capital receipts.
- Spending multiplier 1 ÷ (1 − c); tax multiplier −c ÷ (1 − c); BBM = 1.
- Proportional taxes are automatic stabilisers.
- Deficit is a flow; debt is a stock.
Traps to avoid
- Disinvestment and loan recovery are capital receipts (non-debt).
- Interest paid = revenue expenditure; loan repayment = capital expenditure.
- Table 5.1 prints total expenditure as 1.5; it is 15.0.
- Non-debt capital receipts are 0.2% of GDP, not 9.4% (NCERT's text slip).
- Balanced-budget multiplier is 1.
- Tax multiplier is negative and smaller than the spending multiplier.
- Deficit financed by new money (RBI) is the most inflationary.
- FRBM did not require eliminating the primary deficit (UPSC 2010).
- Macroeconomic Framework Statement: mandated by FRBM Act, not the Constitution.
- GST: destination-based; amendment 2016, rollout 2017.
- A wider deficit in a recession may be automatic, not a policy loosening.
How to strategise
Prelims — what UPSC asks
- Deficits (very frequent): fiscal deficit meaning (1994, 1999, 2001), deficit financing (1987, 1992, 2013), most inflationary financing (2013, 2021), deficit numericals (2025 ×2), FRBM (2006, 2010, 2018, 2020), reducing deficits (2015, 2016).
- Budget classification: capital budget items (2016), capital receipts (2025), non-plan expenditure (1992, 1995, 1997, 2014 — dated), who prepares the budget (2010, 2015).
- Debt: internal debt (2001), gilt-edged market (2000), G-secs and T-bills (2018), household savings and government borrowing (2022), crowding out (2026).
- Taxes: direct vs indirect (2001, 2006, 2009), ad valorem (1988), VAT (2011), GST (2017), tax-to-GDP (2015), redistribution (1996).
- Answer-key notes: UPSC 2025 (revenue deficit ₹80,000 − ₹60,000…) — answer (d): by definition fiscal deficit = borrowing (₹10,000), so statement II holds, and statement III (primary deficit ₹4,000) depends on it; (c) ‘I and III only’ is the trap. UPSC 2015 tax-to-GDP (‘slowing growth’ only) and 1992 deficit financing (‘total expenditure over total revenue’) are debatable but kept.
Mains — where it appears and how to answer
- GS3 2021: capital vs revenue budget and their components — use the tree diagram.
- GS3 2013: FRBM — reasons, features, effectiveness (deferred targets, escape clauses, 2018 debt anchor, Covid).
- GS3 2013: tax expenditure (housing deductions); GS3 2016: gender budgeting; GS3 2015: price subsidy to DBT; GS3 2019: public expenditure management after liberalisation (shared with IED Chapter 3).
- Answer frame for fiscal questions: define (deficits with formulas) → India's numbers (cite year and source) → quality of spending (RD share in FD, capex) → financing (household savings, crowding out, RBI) → rules (FRBM) → balanced conclusion (counter-cyclical flexibility with medium-term anchor).
