ITR Filing Guide FY 2025-26 (AY 2026-27) — Deadline, Which Form, Step-by-Step Process and Penalties

✓ Deadline confirmed: July 31, 2026 for ITR-1/2 — no CBDT extension announced as of July 13, 2026 · Rules verified against Income Tax Act 1961 and Finance Act 2026 · Source: incometax.gov.in

Filing an Income Tax Return is not just a legal obligation for most earning Indians — it is the document that proves your declared income to lenders, visa officers, and government agencies. It is how you claim back TDS deducted in excess of your actual tax liability. And from this year, missing the deadline costs you more than a flat penalty: it eliminates your right to carry forward capital losses that could offset tax on future gains — a loss that could be worth multiples of the ₹5,000 penalty itself.

For FY 2025-26 (Assessment Year 2026-27), India has introduced staggered deadlines for the first time — July 31 for salaried filers (ITR-1 and ITR-2) and August 31 for business and professional filers (ITR-3 and ITR-4). One important technical note: although the Income Tax Act 2025 came into force on April 1, 2026, your ITR for FY 2025-26 is still filed and governed entirely under the Income Tax Act 1961 — because the return covers income earned before the new Act took effect.

This guide covers everything you need to file your ITR correctly: who must file, which form applies to your situation, every document you need to gather, the complete online filing steps, how the refund process works, and exactly what happens if you miss the deadline.

Who Must File an ITR for FY 2025-26?

Filing is mandatory if any of the following applies to you:

• ☑ Your gross total income exceeds ₹4,00,000 (basic exemption limit under the New Regime) or ₹2,50,000 under the Old Regime (₹3,00,000 for senior citizens, ₹5,00,000 for super seniors)
• ☑ You are a resident individual with foreign assets or income from outside India

Which ITR Form Do You Need? — ITR-1 vs ITR-2 vs ITR-4

• ✓ No foreign assets and no foreign income
• ✓ Agricultural income is ₹5,000 or below
• ✓ Not a director in any company
• ✓ Did not hold unlisted equity shares at any point during FY 2025-26

ITR-2 (For salaried individuals with capital gains or multiple income sources)

Use ITR-2 if:

• → You have capital gains from mutual fund redemptions, stock trading, or property sale

• → You have foreign assets or foreign income
• → You are a director in a company
• → You held unlisted equity shares during FY 2025-26

ITR-4 — Sugam (For freelancers and small businesses using presumptive taxation)

Use ITR-4 if:

• → You run a small business with turnover up to ₹3 crore — filing under Section 44AD (presumptive taxation at 8% or 6% of turnover as deemed profit)
• → Your other income is from salary, one house property, and interest only
• → You do not have capital gains or foreign assets

ITR-3 (For business and professional income under regular books)

Documents to Gather Before You Start

Collect all of these before opening the e-filing portal — missing any one mid-session will force you to start over:

From your employer

Form 16 — your employer must issue this by June 15, 2026. Part A shows TDS deducted and deposited. Part B shows your salary breakup, HRA, and all deductions. If you changed jobs during FY 2025-26, collect Form 16 from every employer — all must be consolidated into one ITR.

From the income tax portal (download these first)

Annual Information Statement (AIS) — go to incometax.gov.in → Services → Annual Information Statement. This is the most comprehensive document available and shows every income the tax department knows about: salary TDS, bank interest, dividend income, mutual fund transactions, property purchase/sale, foreign remittances received, and more. Cross-check your own records against AIS — discrepancies between what you report and what AIS shows are a primary trigger for tax notices.

Form 26AS — goes alongside AIS. Shows all TDS credits across employers, banks, and other deductors. Verify every TDS entry matches your Form 16 and bank statements.

From banks

Bank statements for all accounts — for interest income calculation. Interest from savings accounts is taxable (after ₹10,000 deduction under 80TTA for non-seniors). Fixed deposit interest is fully taxable at slab rate. Check all bank accounts including those you rarely use.

Investment and deduction proofs (Old Regime filers)

PPF passbook or statement, ELSS mutual fund statement, life insurance premium receipts, home loan interest certificate from lender (for Section 24b deduction), housing rent receipts (for HRA), health insurance premium receipts (80D), and NPS contribution proof (80CCD).

For capital gains (ITR-2 filers)

Consolidated account statement from CAMS/KFintech for all mutual fund transactions. Broker contract notes or capital gains statement for stock trades. Form 112A from your mutual fund — available from the AMC portal or CAMS — for LTCG on equity funds. Property sale agreement and original purchase documents for property capital gains.

How to Claim a Tax Refund

If more TDS was deducted than your actual tax liability — which is common for people in lower slabs or those with substantial deductions — the excess is automatically refunded to your bank account after your ITR is processed.

You do not file a separate refund application. The refund process is automatic once your ITR is filed and verified.

Deadline Summary — AY 2026-27

Section 234F — The Cost of Filing Late

Beyond the flat fee, late filing has three additional consequences:

One — Interest under Section 234A: If any tax remains unpaid as of the due date, interest accrues at 1% per month (or part of a month) on the outstanding amount from August 1, 2026 until the date of filing. If TDS has covered your full tax liability, no 234A interest applies — but the 234F fee still does.

Two — Loss of carry-forward rights: If you have business losses or capital losses (from stocks or mutual funds) to carry forward to future years, this right is forfeited if you file after the deadline. This is the most consequential cost for investors and traders. A ₹5 lakh capital loss from FY 2025-26, if not carried forward due to late filing, means ₹1,04,000 in additional tax (20% STCG rate) if those gains are realised in the next 8 years. This cost dwarfs the ₹5,000 Section 234F fee.

Three — Delayed refund processing: Belated returns are processed after on-time returns in the Income Tax Department's queue. If you are owed a refund, late filing delays receiving it — and the 0.5% monthly refund interest under Section 244A does not start running until processing begins.

Frequently Asked Questions

What is the last date to file ITR for FY 2025-26 (AY 2026-27)?

The ITR filing deadline for FY 2025-26 depends on which form applies to you. For most salaried individuals filing ITR-1 or ITR-2, the deadline is July 31, 2026 — and no CBDT extension has been announced as of July 2026. Freelancers, consultants, and small business owners filing ITR-4 under presumptive taxation have until August 31, 2026. Business and professional taxpayers whose accounts require a tax audit have until October 31, 2026. If you miss your original deadline, you can still file a belated return under Section 139(4) until December 31, 2026 — but with a mandatory late fee under Section 234F and forfeiture of loss carry-forward rights. For FY 2025-26, the revised return deadline has been extended to March 31, 2027 — an important new provision that gives you more time to correct errors in an already-filed return.

Which ITR form should I use for FY 2025-26?

The form depends on your income sources. ITR-1 (Sahaj) is for resident salaried individuals with income up to ₹50 lakh, no capital gains, no foreign assets, and no directorship. ITR-2 is for anyone with capital gains (from mutual fund redemptions, stock sales, or property transactions), salary above ₹50 lakh, more than one house property, foreign assets, or NRI status. ITR-4 (Sugam) is for freelancers and small business owners using presumptive taxation under Section 44ADA (professionals — 50% of gross receipts treated as profit, income up to ₹75 lakh) or Section 44AD (businesses — 6% or 8% of turnover as profit, turnover up to ₹3 crore). The most common mistake is ITR-1 filers who redeemed mutual fund units during the year — any redemption creates a capital gain that takes you out of ITR-1 into ITR-2.

What documents do I need to file ITR?

The essential documents are: Form 16 from your employer (Part A: TDS deducted; Part B: salary breakup and deductions — must be issued by June 15, 2026), Annual Information Statement (AIS) downloaded from incometax.gov.in (shows all income the tax department knows about), Form 26AS (TDS credit statement — verify every entry matches Form 16), bank statements for all accounts (for interest income), investment proofs for 80C deductions under the Old Regime (PPF passbook, ELSS statements, insurance receipts), home loan interest certificate if claiming Section 24b deduction, and rent receipts if claiming HRA exemption. For capital gains: CAMS/KFintech consolidated account statement for mutual funds and broker capital gains statement for stock trades.

How long does an ITR refund take after filing?

Once your ITR is filed and e-verified (via Aadhaar OTP, net banking, or other methods), refund processing typically takes 20–45 days for straightforward returns with no mismatches. The refund is credited directly to your pre-validated bank account — ensure your bank account is marked "Enabled for Refund" in your profile on incometax.gov.in before filing. Factors that delay refunds: PAN and Aadhaar not linked, bank account not pre-validated, discrepancy between AIS data and ITR declarations, or an outstanding demand from a previous assessment year being adjusted against your refund. You can track refund status at incometax.gov.in or tin.tin.nsdl.com using your PAN and assessment year.

What happens if I miss the July 31, 2026 ITR deadline?

Missing the deadline has four consequences. First, a mandatory flat fee under Section 234F: ₹5,000 if your total income exceeds ₹5 lakh, or ₹1,000 if income is ₹5 lakh or below — this fee applies automatically and cannot be waived even if your tax payable is zero. Second, interest at 1% per month under Section 234A on any tax remaining unpaid as of the due date — if TDS has fully covered your liability this interest does not apply, but the 234F fee still does. Third, forfeiture of the right to carry forward business or capital losses to future years — potentially the most costly consequence for investors with capital losses from FY 2025-26, since those losses can no longer be used to offset future capital gains. Fourth, delayed refund processing — belated returns are processed in a lower priority queue. If you miss July 31, file as soon as possible — every additional month of delay compounds the 234A interest if tax is unpaid, and does not reduce the 234F fee which is flat regardless of how late you file.
