Budget Calendar & Timeline

The Union Budget reaches the public as a single speech on the morning of 1 February. Behind it sits roughly six months of administrative work, and ahead of it another two months of parliamentary process before a single rupee can lawfully be spent. Understanding the calendar explains a great deal about why budgets look the way they do: which numbers are firm, which are provisional, and where an outside observer can actually intervene.

This guide follows one budget year from the first circular to the final regularisation of overspending, using the Union Budget 2026-27 as the running example. GovtBudget.com holds 27 financial years of Union Budget data, from 2000-01 to 2026-27, alongside all 28 states and 8 union territories — 37 Indian governments, each running a version of the cycle described here.

August to October: circulars and ministry estimates

The exercise begins with a piece of administrative post. Each year, usually in late August or September, the Budget Division of the Department of Economic Affairs — the arm of the Ministry of Finance that owns the budget process — issues the Budget Circular to every ministry and department. The circular for 2027-28 went out on 27 August 2026. It asks each ministry to prepare two sets of numbers at once: Revised Estimates for the year already running, and Budget Estimates for the year ahead.

The work is done inside each ministry by its Financial Adviser, an officer who reports both to the ministry and to the Ministry of Finance. Figures are filed through the Union Budget Information System (UBIS), the government's internal budget database; for the 2027-28 round, the filing deadline is 6 October 2026. Pre-budget meetings chaired by the Secretary (Expenditure) are scheduled to begin on 12 October 2026 and run into mid-November.

What ministries are filling in is the skeleton of a constitutional document. Article 112 of the Constitution requires the government to lay before Parliament, for every financial year, an Annual Financial Statement — the estimated receipts and expenditure of the Government of India. That statement must distinguish revenue expenditure (salaries, subsidies, interest) from other expenditure, and must separate spending charged on the Consolidated Fund of India, which Parliament cannot vote on, from spending submitted to the vote. Every line a ministry enters in October eventually surfaces in one of those columns.

November to January: negotiation and finalisation

The autumn filings are opening bids. Through November the Department of Expenditure works through them ministry by ministry, setting ceilings that rarely match what was asked for. The Department of Economic Affairs simultaneously builds the macro-fiscal frame — nominal GDP growth, borrowing capacity, the deficit path — which decides how large the total can be.

The revenue side is assembled separately by the Department of Revenue, working with the Central Board of Direct Taxes and the Central Board of Indirect Taxes and Customs. An important limit applies here: GST rates are not set in the Budget. They are recommended by the GST Council, a constitutional body under Article 279A. The GST 2.0 structure in force since 22 September 2025 — a nil rate, two main slabs of 5% and 18%, and a 40% rate on luxury and sin goods, with the old 12% and 28% slabs withdrawn — came from the Council, not from a Finance Bill.

One further constraint is settled outside the Ministry of Finance. The Finance Commission, appointed under Article 280, fixes the states' share of central taxes. The Sixteenth Finance Commission, chaired by Arvind Panagariya, covers 2026-27 to 2030-31 and kept the states' share of the divisible pool at 41%, the same as its predecessor. That devolution is deducted before the Union's own spending is finalised.

From December the Finance Minister holds consultations with industry bodies, farmers' organisations, economists, trade unions and state finance ministers. In late January the customary halwa ceremony marks the start of the lock-in, when officials preparing the documents are sequestered. The Economic Survey, prepared by the Chief Economic Adviser, is tabled shortly before Budget Day; the 2025-26 Survey was tabled on 29 January 2026.

Budget Day and the immediate aftermath

Since 2017 the Budget has been presented on 1 February, moved forward from the end of February so that parliamentary approval can be completed before the financial year begins on 1 April. The same reform folded the separate Railway Budget into the Union Budget from 2017-18. The Budget for 2026-27 was presented on 1 February 2026: total expenditure of Rs 53.47 lakh crore, total receipts other than borrowings of Rs 36.52 lakh crore, and a fiscal deficit of Rs 16.96 lakh crore, or 4.3% of GDP. Within the total, capital expenditure is Rs 12.22 lakh crore and interest payments Rs 14.04 lakh crore — the single largest item of committed spending.

The speech is only the covering note. Alongside it the government lays the Annual Financial Statement, the Demands for Grants, the Finance Bill, Budget at a Glance, the Receipt Budget, the Expenditure Profile and the statements required under the Fiscal Responsibility and Budget Management Act. The documents have been circulated electronically, through the Union Budget Mobile App, since the paperless Budget of 2021-22.

Two things take effect immediately. The Finance Bill is introduced as soon as the speech ends, and under the Provisional Collection of Taxes Act, 2023 — which replaced the 1931 Act of the same name — declared changes to customs and excise duties come into force at the expiry of that day. Those provisional levies lapse 75 days after introduction unless the Finance Bill has been enacted. Everything else remains a proposal. On Budget Day none of the Rs 53.47 lakh crore is yet authorised: the Rajya Sabha has the Budget laid before it, but only the Lok Sabha can grant the money.

The two-stage Parliamentary approval process

Parliament examines the Budget in two stages, separated by a recess.

Stage one is the general discussion, held in both Houses over several days after presentation. Members speak on the Budget as a whole; no amendments are moved and nothing is voted. The Houses then adjourn so that the 24 Departmentally Related Standing Committees — each with 31 members, 21 from the Lok Sabha and 10 from the Rajya Sabha — can examine the Demands for Grants of the ministries assigned to them and report. Their reports are recommendatory, and they are the most detailed public scrutiny the Budget receives.

Stage two begins when the Houses reassemble. Under Article 113, estimates of voted expenditure are submitted to the Lok Sabha as Demands for Grants; charged expenditure — interest on debt, the emoluments of the President, the salaries of Supreme Court judges and of the Comptroller and Auditor General, court decrees — may be discussed but not voted. No demand can be made except on the President's recommendation. Members may move cut motions (policy, economy or token cuts) to register disapproval.

Time is short, so the Business Advisory Committee selects a handful of ministries for detailed debate. On the last allotted day the Speaker applies the guillotine, putting all outstanding demands to the vote together, discussed or not.

The grants are then given legal force by an Appropriation Bill under Article 114, because no money may be withdrawn from the Consolidated Fund of India except under an appropriation made by law. The Finance Bill, carrying the tax proposals, follows. Both are Money Bills: the Rajya Sabha may recommend changes but must return them within 14 days. If the process cannot be finished before 1 April — most obviously in a general election year — Parliament passes a vote on account under Article 116, an advance grant to keep government running.

Mid-year: Revised Estimates and supplementary demands

A budget is a forecast, and the government revises it while it runs. Each Budget therefore carries two sets of figures for the current year as well as the new one. The Revised Estimates for 2025-26, presented with the 2026-27 Budget, put total expenditure at Rs 49.65 lakh crore and the fiscal deficit at about Rs 15.6 lakh crore, or 4.4% of GDP. For analysts, Revised Estimates are usually the more honest number: they are compiled around eight months into the year, with most receipts and spending already visible.

Where a sanctioned grant proves insufficient, or a new service arises, the government returns to Parliament with Supplementary Demands for Grants under Article 115. These are typically presented in more than one batch during the year — commonly in the winter session and again in the second part of the budget session — and each batch is followed by its own Appropriation Act. Two figures are quoted for every batch: gross additional expenditure, and the smaller net cash outgo after savings elsewhere are offset.

For spending that cannot wait for Parliament, the Contingency Fund of India exists under Article 267. It is placed at the disposal of the President, advances are made from it by executive order, and the amounts are recouped once Parliament authorises the spending. Its corpus was raised from Rs 500 crore to Rs 30,000 crore by the Finance Act, 2021.

The cycle closes late. Where a ministry has actually spent more than it was granted, the excess is regularised only after the Comptroller and Auditor General reports it in the Appropriation Accounts and the Public Accounts Committee examines it — a demand for excess grants that often reaches Parliament two years or more after the money was spent.
