ITR Documents Checklist (India): What to Collect Before Filing

About the ITR Documents Checklist (India): What to Collect Before Filing

Most mistakes in an income-tax return start with a missing paper: interest that is in the Annual Information Statement but not in the return, a second employer’s salary, a capital gains statement nobody downloaded, a deduction claimed without its proof. Tick what applies to you — salary or pension, house property and a home loan, interest and dividends, capital gains from shares, mutual funds, property or crypto, F&O or intraday trading, a business or presumptive income, foreign income or assets, agricultural income, a directorship or unlisted shares — and this checklist gives you the documents to collect, each with why it matters and where it comes from.

It also shows the ITR form that usually applies (ITR-1, 2, 3 or 4) and why, the schedules you will fill, the due date for your case — with the belated and revised return dates once it has passed — and the mismatch traps that cause notices. Choose the return for FY 2025-26 or for Tax Year 2026-27, the first year under the Income-tax Act, 2025, where Form 16 becomes Form No. 130. Print it or save it as a PDF; nothing you tick is stored.

Common uses

• Getting your papers together before sitting down to file, or before handing them to a tax professional.
• Checking whether ITR-1 still fits after selling shares or buying a second house.
• Finding the due date, and what you can still do after it has passed.
• A first return under the Income-tax Act, 2025, with its new form numbers.

Which form

• ITR-1 (Sahaj): a resident (not “not ordinarily resident”) individual with total income up to ₹50 lakh from salary or pension, up to two house properties, interest and other sources, and up to ₹1.25 lakh of long-term gains on listed shares and equity funds. Not for directors, holders of unlisted shares, anyone with foreign assets or income, agricultural income above ₹5,000, losses brought or carried forward, deferred ESOP tax or TDS on cash withdrawals.
• ITR-4 (Sugam): the same with presumptive business or professional income (sections 44AD, 44ADA, 44AE; section 58), also for HUFs and firms. Optional — ITR-3 can always be used.
• ITR-2: individuals and HUFs without business income who cannot use ITR-1 — for example with capital gains, foreign assets or income above ₹50 lakh.
• ITR-3: individuals and HUFs with business or professional income from books, F&O or intraday trading, or presumptive income that does not fit ITR-4.

For Tax Year 2026-27 the forms follow rule 164 of the Income-tax Rules, 2026.

Due dates

Without business income, the return is due by 31 July after the year; with business or professional income and no audit by 31 August (the Finance Act, 2026 added this date); with an audit by 31 October, and by 30 November with a transfer-pricing report. For FY 2025-26 the CBDT extended the audit-case date to 21 November. After the due date you can still file a belated return until 31 December after the year, with a fee of ₹1,000 (income up to ₹5 lakh) or ₹5,000 if you have to file, and interest on unpaid tax — but losses other than a house-property loss cannot be carried forward — and a revised return until 31 March, a year after the year ends.

The forms with new numbers

Under the Income-tax Rules, 2026: Form 16 → Form No. 130, Form 16A → Form No. 131, Forms 16B to 16E → Form No. 132, Form 12BA → Form No. 123, Form 12B → Form No. 122, Form 12BB → Form No. 124, Form 10E → Form No. 39, Form 67 → Form No. 44, Form 10BA → Form No. 31, Form 10BE → Form No. 114, and the Annual Information Statement is Form No. 168. Leaving the new regime with business income needs no separate form: the option is made in the return filed by the due date (rule 136).

Limitations

• A checklist, not a review: it does not read your documents or work out your tax.
• For individuals and HUFs. Firms, companies and trusts file ITR-5, ITR-6 or ITR-7.
• The ITR form is the usual one for what you tick; a rare income can change it. The e-filing utility checks the form when you file.
• Return forms for Tax Year 2026-27 are filed in 2027 and may arrange the schedules differently.
