Understanding the Union Budget can feel overwhelming when you hear economic terms like inflation, fiscal deficit, GDP or tax revenue. These terms form the backbone of how government finances are planned, administered, and interpreted by markets, individuals, and policymakers.

This blog breaks down the most important budget terms, helping you read, follow and interpret Budget announcements with confidence — especially ahead of India’s Union Budget 2026.

What Is the Union Budget?

The Union Budget is the government’s annual financial statement showing expected revenue and planned expenditure for the next financial year. It outlines taxation, fiscal targets, welfare spending, infrastructure plans and updates on economic strategy.

📊 Key Budget Terms You Must Know

Inflation

Inflation measures how fast prices of goods and services are rising over time. It represents the decline in purchasing power — if inflation is high, your money buys less. Governments and central banks use fiscal and monetary policy to manage inflation.

Fiscal Deficit

This is one of the most watched budget numbers. Fiscal deficit occurs when the government’s total expenditure exceeds its total revenue excluding borrowings. It shows how much the government needs to borrow to fund its plans.

Why it matters: A higher fiscal deficit can mean more borrowing, which affects interest rates and bond markets, but moderate deficits can stimulate growth during slowdown.

Gross Domestic Product GDP

GDP is the total market value of all goods and services produced within a country in a year. It’s the broadest measure of economic activity.

Growth in GDP indicates economic expansion; contraction indicates slowdown. Policies in the Budget often aim to boost GDP growth.

Disinvestment

The sale of shares of public sector undertakings by the government is called disinvestment. The shares of government companies held by the government are the assets at the disposal of the government. If these shares are sold to get cash, then earning assets are converted into cash . So it is referred to as disinvestment.

GST

Proposed to be rolled out in India from April 1, 2016, the GST seeks to make the indirect tax structure simpler and efficient by replacing a slew of levies such as octroi, central sales tax, State sales tax, entry tax and so on.

Primary deficit

The primary deficit is the fiscal deficit minus interest payments. It tells how much of the government’s borrowings are going towards meeting expenses other than interest payments.

Direct tax

A tax, such as the income-tax and corporate tax, which has to be borne by the person or entity it is imposed on.

Indirect tax

A tax on goods and services, typically, levied on an entity but paid by another. They are paid by consumers when they buy goods and services. These include excise duty, customs duty etc.

Excise duty

An indirect tax levied on goods manufactured in India and meant for home consumption.

Customs duty

These are levies charged when goods are imported into, or exported from, the country, and they are paid by the importer or exporter. Usually, these are also passed on to the consumer.

Monetary Policy

Monetary policy is what a central bank RBI does to influence the course of an economy through decisions on money supply and interest rate.

Capital Budget

The Capital Budget consists of capital receipts and payments. It includes investments in shares, loans and advances granted by the Central Government to State Governments, Government companies, corporations and other parties.

Revenue Receipts

Revenue receipts are income earned by the government that does not create a liability or reduce assets, e.g., tax revenue and non-tax revenue.

Capital expenditure

Capital expenditure or capex, is the money spent by the government on development or to acquire, or to upgrade machinery or assets. Capital payments consist of capital expenditure on acquisition of assets like land, buildings, machinery, equipment, as also investments in shares, etc., and loans and advances granted by the Central Government to the State and the Union Territory Governments, Government companies, Corporations and other parties.

Capital Receipts

Capital receipts either create a liability for the government borrowings or reduce assets disinvestment proceeds.

Revenue Deficit

Revenue deficit arises when revenue expenditure day-to-day running costs like salaries, subsidies, interest payments exceeds revenue receipts. It signals that the government isn’t generating enough to cover its ongoing operations.

Fiscal Policy

This refers to how the government uses taxation and expenditure to influence economic activity. By tweaking taxes and spending, fiscal policy can stimulate growth or contain inflation.

Public Account

This consists of funds the government holds on behalf of others, such as provident funds, small savings or court deposits — essentially money it must eventually return.
