Every year around February, the finance minister stands up in Parliament and reads out a document that decides how much India will spend on roads, schools, defence, and welfare schemes. But before any of that spending can happen, the government needs money. Where does it come from? This is the question public revenue answers, and understanding it is the first step to making sense of India’s entire fiscal policy.

What counts as public revenue
Public revenue is the income the government collects to run the country. It is not just about taxes. The Union Budget classifies government receipts into two broad heads: revenue receipts and capital receipts. Revenue receipts are recurring in nature and do not create any liability or reduce any asset for the government. Capital receipts, on the other hand, either create a liability (like a loan the government has to repay) or reduce an asset (like selling shares in a public sector company).
This distinction matters because it tells you something about the quality of government finances. A government that funds its spending mostly through taxes and stable non-tax income is on firmer ground than one that leans heavily on borrowing to pay its bills.
Revenue receipts: tax and non-tax income
Revenue receipts are the government’s “current income,” similar to a salary you earn every month. They come from two sources: taxes and non-tax sources.
Tax revenue
Tax revenue is money the government collects compulsorily from individuals and businesses, without promising anything specific in return. You pay income tax, but you cannot demand a particular road be built in your neighbourhood because of it. This is what separates a tax from a fee.
Under the Constitution of India, no tax can be levied or collected without the backing of a law passed by Parliament or a state legislature. This single rule, found in Article 265, is why every new tax or change in tax rate has to go through a legislative process rather than being imposed by an executive order.
Tax revenue is usually split into two categories:
- Direct taxes: Paid straight from the taxpayer’s pocket to the government, with the burden falling on the same person who pays it. Income tax and corporate tax are the two biggest examples.
- Indirect taxes: Collected by an intermediary (like a shopkeeper) and passed on to the government, but the actual burden falls on the final consumer through higher prices. GST, customs duty, and excise duty on items like petrol fall here.
Tax revenue forms the largest share of government income by a wide margin. According to a Business Standard analysis of the Union Budget, tax revenue constitutes the lion’s share of the government’s income and directly reflects the strength of economic activity and the government’s ability to mobilise resources. This is one reason economists watch GST collections so closely every month: a slowdown in collections often signals a slowdown in the broader economy.
Non-tax revenue
Non-tax revenue is income the government earns without invoking its taxing power. It is smaller than tax revenue but plays an important cushioning role when tax collections fall short.
The main sources of non-tax revenue include:
- Interest receipts: Interest earned on loans the central government has given to state governments, union territories, and public sector enterprises.
- Dividends and profits: Profits transferred to the government by public sector undertakings such as Indian Railways, ONGC, and public sector banks, as well as the Reserve Bank of India’s annual surplus transfer.
- Fees and fines: Charges for services like passport issuance, court fees, registration fees, and penalties for violations.
- Grants: Financial assistance received from foreign governments or international institutions, though this is a relatively minor component for India today.
The scale of non-tax revenue is significant even though it trails tax revenue. A PRS Legislative Research analysis of the Union Budget 2026-27 notes that non-tax revenue was estimated at over Rs 6.6 lakh crore, with dividends and profits from public sector enterprises and the RBI accounting for around 59 percent of that figure. This shows how much the government relies on the profitability of its own enterprises and the central bank to supplement its income.
Capital receipts: money that isn’t quite “revenue”
Capital receipts differ from revenue receipts in one crucial way: they either add to the government’s liabilities or reduce its assets. Money borrowed today has to be repaid tomorrow with interest. Selling a stake in a public company reduces what the government owns, even if it brings in cash right now.
Borrowings and loans
The government raises loans from the public through instruments like government bonds and treasury bills, auctioned by the Reserve Bank of India as the government’s debt manager. It can also borrow from foreign governments and multilateral institutions. This category of receipts is called “debt capital receipts” because it creates a repayment obligation.
Disinvestment
Disinvestment means the government selling part or all of its ownership stake in a public sector undertaking. This is a one-time inflow rather than a recurring one. It is also a bit of a trade-off: selling a profitable PSU brings in cash immediately but forfeits future dividend income that would otherwise have counted as non-tax revenue. The PRS analysis mentioned above notes that the disinvestment target for 2026-27 was set higher than the previous year, reversing a five-year trend of downward revisions and shortfalls.
Recovery of loans
The central government has, over the decades, extended loans to state governments, union territories, and other bodies. When these loans are repaid, the repayment is booked as a capital receipt because it reduces a financial asset the government held. Together, recovery of loans and disinvestment proceeds are classified as “non-debt capital receipts,” a category budget documents actively try to grow so the government relies less on fresh borrowing.
Comparing the sources at a glance
| Category | Nature | Examples |
|---|---|---|
| Tax revenue | Compulsory, recurring, no direct benefit promised | Income tax, corporate tax, GST, customs duty |
| Non-tax revenue | Non-compulsory, recurring, often tied to a service | Interest receipts, PSU dividends, fees, fines, grants |
| Capital receipts (debt) | Creates a future repayment liability | Market loans, treasury bills, external borrowings |
| Capital receipts (non-debt) | Reduces a government asset, one-time inflow | Disinvestment proceeds, recovery of loans |
Why this classification actually matters
This is not just an academic exercise in categorisation. The distinction between revenue receipts and capital receipts directly feeds into how India measures its fiscal health. The gap between total revenue receipts and total revenue expenditure is called the revenue deficit, and it tells you whether the government is spending more on day-to-day operations than it earns from recurring sources. A widening revenue deficit, financed by more borrowing, means the country is taking on debt to pay for things like salaries and subsidies rather than for building assets like highways or hospitals.
Similarly, an over-reliance on capital receipts like disinvestment to plug budget gaps can be a warning sign. It might make a single year’s numbers look better, but it does nothing to fix the underlying mismatch between what the government earns and what it spends. This is why analysts pay close attention not just to the total revenue figure in the budget, but to its composition: how much comes from stable, recurring sources versus one-off inflows.
Bringing it together
Public revenue is really the financial bloodstream of the government. Tax revenue does the heavy lifting, non-tax revenue adds a useful cushion, and capital receipts fill in the gaps, sometimes through healthy avenues like loan recoveries and sometimes through borrowing that has to be repaid with interest. For anyone studying fiscal policy, tracking how this mix shifts from one budget to the next is often a better indicator of the government’s financial direction than the headline spending numbers alone.
What do you think? If a government leans more on disinvestment and borrowing than on taxes and PSU dividends to fund its spending, what does that suggest about the sustainability of its finances? And why might a state government’s flexibility with non-tax revenue, like fees and fines, be more limited than what you’d expect?
