Fiscal Policy: Types of Taxes, Direct and Indirect Taxes, Public Expenditure, Public Debt and Deficit Financing

Updated 17 October 2026 · Fact-checked

Fiscal policy is the government's policy on taxation, public expenditure and public debt to achieve economic objectives such as growth, stability and equity. Taxes are progressive, proportional, regressive or degressive according to how the rate changes as income rises, and direct or indirect according to whether the burden can be shifted. Public debt is repaid (redeemed) through methods such as a sinking fund, and deficit financing means meeting a budget gap by borrowing from the central bank or creating new money.

Follow each line as income rises: progressive climbs, proportional stays flat, regressive falls, and degressive rises only until the limit.

Understand Taxes, Public Expenditure and Public Debt in Fiscal Policy

1. Meaning, objectives and instruments. Fiscal policy uses the government's budget to influence the economy. Main objectives: economic growth, full employment, price stability, reduction of inequalities of income and wealth, and mobilising resources. Instruments: taxation (public revenue), public expenditure, public debt and the budget itself (surplus, deficit or balanced).

2. Public revenue and taxes. Public revenue is the income of the government from taxes and other sources. A tax is a compulsory payment by citizens and firms to the government, without any direct return benefit. Classification by rate:

Progressive tax: the rate rises as income rises (a higher slab pays a higher percentage); it reduces inequality.
Proportional tax: a fixed rate at all income levels; the tax amount rises in proportion to income.
Regressive tax: the rate falls as income rises, so the burden is heavier in relation to the income of the poor.
Degressive tax: the rate rises with income only up to a limit or at a diminishing pace, and then becomes constant (a mildly progressive structure, which turns proportional).

3. Direct and indirect taxes.

Direct tax: its impact and incidence fall on the same person (it cannot be shifted); examples: income tax, corporation tax, wealth tax. It is generally progressive and based on ability to pay.
Indirect tax: imposed on goods and services; the legal payer (seller) shifts the burden to the consumer; examples: GST, customs duty, excise duty. It is wide-reaching and easy to collect, but often regressive because everyone pays on the same item regardless of income.
Difference points: incidence, shifting, equity, evasion (easier in direct), collection, and effect on prices (indirect taxes raise prices).

4. Public expenditure (meaning and importance). Spending by the government on its administration, defence, social services (education, health), infrastructure, subsidies and welfare. Importance: provides public goods that the market under-supplies, reduces inequality (through transfers and subsidies), raises employment and income (through the multiplier), stabilises the economy (more spending in a slump), and promotes regional development.

5. Public debt and its redemption. Public debt is the amount a government owes after borrowing from the public, banks, the central bank or foreign sources (internal and external debt). Redemption (repayment) methods:

Sinking fund: a fund into which the government pays a regular amount to repay the debt on maturity.
Surplus budget: using a budget surplus to repay.
Conversion: replacing old high-interest loans by new low-interest ones (saves interest cost).
Refunding: raising new loans to repay old ones.
Annuities: repaying in equal instalments over the years.
Repudiation (refusal to pay) is rare and harms the government's credit.

6. Deficit financing (meaning only). Meeting a budget deficit by borrowing from the central bank (new money creation) rather than from the public. It raises the money supply and, if output cannot rise, can be inflationary; used carefully it supports spending in a slump.

Taxes, Public Expenditure and Public Debt in Fiscal Policy: key facts

Average tax rate: Tax rate = tax / income x 100
Annual sinking fund (no interest): Annual contribution = debt / number of years
Interest saved by conversion: Saving = loan x (old rate - new rate)
Burden test: Progressive: tax rate rises with income; regressive: falls

How to answer Taxes, Public Expenditure and Public Debt in Fiscal Policy questions

Classify taxes by calculating the tax rate at each income level.

1Compute the average rate = tax / income x 100 at each income.
2Rate rising throughout: progressive. Constant: proportional. Falling: regressive. Rising then constant: degressive.
3For direct versus indirect, ask whether the person who pays the government also bears the burden.
4For debt problems, divide by the number of years (sinking fund) or multiply the rate difference by the loan (conversion).
5Link the measure to its objective (growth, equity, stability).

Taxes, Public Expenditure and Public Debt in Fiscal Policy in real life

The idea, met in an everyday situation. Answer the question in your own words, then compare with the model answer. The one-line hook is what to remember.

Three taxpayers and the tax slab

Suppose a country levies income tax at 4% on an income of Rs 3,00,000, 8% on Rs 6,00,000 and 15% on Rs 12,00,000.

What type of tax is this, and how much tax does each pay?

Try it first, then show the solutionSolution

Tax: 4% of 3,00,000 = Rs 12,000; 8% of 6,00,000 = Rs 48,000; 15% of 12,00,000 = Rs 1,80,000.
The rate rises with income: progressive.

Answer: It is a progressive tax: Rs 12,000, Rs 48,000 and Rs 1,80,000, with the richest paying the highest share of income.

Memory hook: More income, higher rate.

Ordered from board level to HOTS. Try each one before you open the solution.

Example 1: Shifting the burden · 1 mark · MCQBoard level

A tax whose burden can be shifted from the person who pays it to someone else is called:
(a) direct tax
(b) indirect tax
(c) progressive tax
(d) proportional tax

Try it first, then show the solutionSolution

Indirect taxes are paid by sellers and passed on to consumers through the price.

Answer: (b) indirect tax

Example 2: Identifying the type of tax · 3 marks · Short answerBoard level

A person with an income of Rs 1,50,000 pays Rs 6,000 as tax, with Rs 3,00,000 pays Rs 18,000 and with Rs 6,00,000 pays Rs 48,000. Find the tax rate at each income and the type of tax. (3 marks)

Try it first, then show the solutionSolution

Rates: 6,000/1,50,000 = 4%; 18,000/3,00,000 = 6%; 48,000/6,00,000 = 8%.
The rate rises with income, so the tax is progressive.

Answer: Rates of 4%, 6% and 8%: a progressive tax.

Example 3: Comparing four structures · 4 marks · Short answerHarder board level

Incomes are Rs 3,00,000, Rs 6,00,000 and Rs 12,00,000. Find tax amounts under (a) rates 4%, 8%, 15%; (b) a flat 10%; (c) rates 12%, 10%, 6%; (d) rates 5%, 10%, 10%. Name each type. (4 marks)

Try it first, then show the solutionSolution

(d) 15,000; 60,000; 1,20,000: degressive (the rate rises up to Rs 6,00,000, then stays at 10%).

Answer: (a) progressive, (b) proportional, (c) regressive, (d) degressive, with the tax amounts above.

Example 4: Redeeming public debt · 4 marks · Short answerHarder board level

A government has a debt of Rs 10,000 crore due after 10 years. (a) If it pays equal yearly sums into a sinking fund (ignoring interest earned), how much must it pay each year? (b) Old bonds worth Rs 5,000 crore pay 9% interest; it replaces them with 7% bonds. How much interest does it save in a year, and what is this method called? (4 marks)

Try it first, then show the solutionSolution

(a) 10,000 / 10 = Rs 1,000 crore a year.
(b) Interest before = 5,000 x 9% = Rs 450 crore; after = 5,000 x 7% = Rs 350 crore; saving = Rs 100 crore a year.
The replacement of old loans by new cheaper loans is conversion.

Answer: (a) Rs 1,000 crore a year; (b) saves Rs 100 crore a year by conversion of debt.

Example 5: Equity effect of the tax structure · 4 marks · Short answerHOTS / competency

Two persons earn Rs 3,00,000 and Rs 12,00,000. Using the progressive tax of the earlier example (Rs 12,000 and Rs 1,80,000) and the regressive tax (Rs 36,000 and Rs 72,000), find their after-tax incomes and the ratio of the higher to the lower under each. Which tax narrows the gap? (4 marks)

Try it first, then show the solutionSolution

Before tax the ratio is 12,00,000 / 3,00,000 = 4.
Progressive: 2,88,000 and 10,20,000; ratio = 10,20,000 / 2,88,000 = about 3.54.
Regressive: 2,64,000 and 11,28,000; ratio = about 4.27.
The progressive tax narrows the gap (4 to 3.54); the regressive tax widens it (4 to 4.27).

Answer: Progressive: ratio falls to about 3.54; regressive: ratio rises to about 4.27. A progressive tax reduces inequality, and a regressive tax increases it.

Where students lose marks in Taxes, Public Expenditure and Public Debt in Fiscal Policy

The slips examiners see most often, and what to write instead.

Mistake: Defining regressive tax as a tax with a falling amount
Mixing the amount with the rate.
Wrong working
Regressive tax: the tax paid falls as income rises.
Right working
Regressive: the rate falls as income rises, although the amount paid may still rise or stay the same.
Do this: Always talk about the rate.
Usually costs: 2 marks.
Mistake: Calling GST a direct tax
Because the seller pays.
Wrong working
GST is a direct tax as it is paid to the government.
Right working
GST is an indirect tax: the burden is passed on to the consumer.
Do this: Use the shifting test.
Usually costs: 1 mark.
Mistake: Mixing redemption methods
Not knowing the terms.
Wrong working
Conversion means repudiating the debt.
Right working
Conversion replaces high-interest debt with low-interest debt.
Do this: Learn the one-line meaning of each method.
Usually costs: 1-2 marks.
Mistake: Treating deficit financing as any borrowing
Over-general definition.
Wrong working
Deficit financing is borrowing from the public.
Right working
Deficit financing is meeting a deficit by borrowing from the central bank or creating new money.
Do this: Mention the new money.
Usually costs: 1 mark.

Exam tips

Classify taxes with a small table of income, tax and rate; the rate pattern decides the type.
For direct versus indirect taxes, give three differences and one example each.
Public expenditure: write meaning and four points of importance (public goods, reducing inequality, employment, stabilisation).
Public debt: meaning and at least three methods of redemption, with the sinking fund explained.
Deficit financing is meaning only; do not write long answers.

Q1 · 1 mark · MCQBoard level
A tax levied at the same rate on all levels of income is:
(a) progressive
(b) proportional
(c) regressive
(d) degressive
Hint
Same rate means the amount is proportional to income.
Answer
(b) proportional
Q2 · 3 marks · Short answerBoard level
Distinguish between direct and indirect taxes on any three points, giving one example of each. (3 marks)
Hint
Think of incidence, shifting and equity.
Answer
Direct tax: impact and incidence on the same person (not shifted); progressive and based on ability to pay; evasion easier. Example: income tax. Indirect tax: burden shifted to the consumer through prices; levied on goods and services; usually regressive; wide coverage. Example: GST.
Q3 · 4 marks · Short answerHarder board level
Incomes of Rs 2,00,000, Rs 4,00,000 and Rs 8,00,000 pay taxes of Rs 8,000, Rs 24,000 and Rs 80,000. Find the average tax rates and the extra tax paid per extra rupee of income between consecutive incomes. Name the type. (4 marks)
Hint
Extra tax divided by extra income.
Answer
Average rates: 8,000/2,00,000 = 4%; 24,000/4,00,000 = 6%; 80,000/8,00,000 = 10%. Extra tax per extra rupee: (24,000 - 8,000)/2,00,000 = 8% and (80,000 - 24,000)/4,00,000 = 14%. The rate rises with income: progressive.
Q4 · 4 marks · Short answerHarder board level
A government has a debt of Rs 6,000 crore maturing in 12 years. (a) Find the equal yearly sinking fund contribution, ignoring interest. (b) It converts Rs 3,000 crore of 8% loans into 6.5% loans; find the yearly interest saved. (4 marks)
Hint
Divide, then multiply by the rate difference.
Answer
(a) 6,000 / 12 = Rs 500 crore a year. (b) Saving = 3,000 x (8% - 6.5%) = 3,000 x 1.5% = Rs 45 crore a year.
Q5 · 3 marks · Short answerHOTS / competency
The government finances a deficit of Rs 2,000 crore by borrowing from the central bank, which creates that much new base money. If banks hold 20% reserves and there is no cash drain, find the potential rise in deposits and explain why this deficit financing can be inflationary. (3 marks)
Hint
Multiplier = 1/0.2.
Answer
Potential deposits = 2,000 x 5 = Rs 10,000 crore. Money supply rises sharply while output may not; the extra demand chases the same goods, raising prices (inflationary pressure), particularly near full employment.
