Documents You Need for ITR Filing in AY 2026-27

What documents are required for ITR filing AY 2026-27? You need PAN, Aadhaar, Form 16 (salaried), Form 26AS, Annual Information Statement (AIS), bank statements, investment proofs under Section 80C/80D, and capital gains statements. Business filers additionally need P&L accounts, balance sheets, and GST returns.

Filing your Income Tax Return for Assessment Year 2026-27 (covering income earned during Financial Year 2025-26) requires a well-organised set of documents. Missing even a single form, whether it is a TDS certificate or a capital gains statement, can delay your business ITR filing or personal filing, trigger a defective return notice under Section 139(9), or result in missed deductions that increase your tax liability.

This checklist covers every document category for business ITR filings and personal returns: universal identity proofs, salary-related forms, business records, capital gains evidence, deduction proofs, foreign income disclosures, and the critical AIS/TIS/Form 26AS reconciliation. Whether you are a salaried employee, freelancer, small business owner, or investor, use this as your pre-filing reference.

Universal Documents (All Taxpayers)

Every taxpayer, regardless of income source or ITR form type, must have these documents ready before filing.

Documents for Salaried Individuals

If you earn salary income, these documents form the backbone of your ITR 1 (Sahaj) or ITR 2 filing.

Form 16 (Parts A and B)

Form 16 is the TDS certificate issued by your employer under Section 203. Part A shows TDS deducted and deposited quarter-wise; Part B is a detailed computation of your salary income, exemptions claimed (HRA, LTA), and deductions allowed.

Note on Income Tax Act 2025: Form 130 replaces Form 16 only for salary paid from 1 April 2026 (Tax Year 2026-27). For AY 2026-27 (salary of FY 2025-26), your employer issues Form 16 under the 1961 Act, due by 15 June 2026.

AIS, TIS, and Form 26AS: The Reconciliation Trio

Before you begin filling your ITR, reconciling these three documents is the single most important step to ensure accuracy.

What Each Document Shows

Reconciliation Checklist

1. Download all three from the Income Tax e-filing portal.
2. Match TDS amounts in Form 26AS with your Form 16/16A certificates.
3. Verify every AIS entry: interest from each bank account, dividends from each company, mutual fund transactions, property registrations.
4. Flag discrepancies: If AIS shows income you did not earn (e.g., incorrect SFT reporting by a bank), submit feedback on the AIS portal before filing.
5. Check TIS derived values: The "Processed Value" in TIS may differ from your actual income if you submitted AIS feedback. Ensure TIS reflects corrections.

Frequently Asked Questions

Do I need to attach documents or proofs when filing my ITR online?

No. ITRs are annexure-less, so you do not upload Form 16, rent receipts or investment proofs with the return. You only enter the figures. Keep all documents safely for at least six years, because the department can ask for them during processing, verification or scrutiny, and a deduction you cannot support with proof can be disallowed with interest and penalty.

Can I file my ITR without Form 16 if my employer has not issued it?

Yes. Form 16 is a convenience, not a legal requirement for filing. You can compute salary from your payslips and bank credits and take TDS figures from Form 26AS and AIS. Employers must issue Form 16 by 15 June, so if it is missing, check that the employer's TDS return is reflected in Form 26AS before claiming credit.

What document shows the TDS deducted when I sold a property?

When the buyer deducts 1% TDS under Section 194-IA on a sale of Rs 50 lakh or more, they file the challan-cum-statement in Form 26QB and must give you Form 16B, the TDS certificate, downloaded from TRACES. The TDS also appears in your Form 26AS and AIS under your PAN. You need the sale deed, purchase deed and cost of improvement bills to compute the capital gain.

Do I need investment proofs if I file under the new tax regime?

Mostly no. Under the new regime you cannot claim deductions such as 80C, 80D, HRA or home loan interest on a self-occupied house, so their proofs are not needed. You still need Form 16, AIS, Form 26AS, bank interest details and capital gains statements, and proof of employer NPS contribution if you claim the 80CCD(2) deduction, which is allowed under the new regime.

Which documents do I need to report foreign stocks or RSUs in my ITR?

Keep the broker or plan statements showing grant, vesting, sale and dividend details, the exchange rates used, and proof of foreign tax withheld. RSUs taxed as perquisites appear in Form 16. You must report foreign holdings in Schedule FA on a calendar-year basis, foreign income in Schedule FSI, and file Form 67 on or before the end of the assessment year (ideally with the ITR) if you claim foreign tax credit.
