Income Tax · Document Checklist
Documents Required For ITR Filing (India, 2026)
Most of the stress in filing an income tax return comes from hunting for documents halfway through. If you gather everything first, the filing itself is usually quick. This checklist groups the documents required for ITR filing into identity, income, tax-paid and deduction proofs, so you can collect them in one go, whether you file yourself or hand it to a professional.
- Identity: PAN, Aadhaar (linked to PAN), and a pre-validated bank account for any refund.
- Salary: Form 16 is the main document; keep salary slips if needed.
- Tax paid: check Form 26AS and the AIS on the portal and reconcile them with your own records before filing.
- Capital gains: keep the broker or fund capital gains statement and property sale and purchase documents.
- Deductions: keep 80C, 80D, home loan interest and HRA proofs; which ones help depends on your regime.
- Keep, do not upload: for most returns you file on the figures and retain the documents as backup.
01Identity and basic details
These establish who you are and where your refund goes.
- PAN: your Permanent Account Number, used to log in and as your tax identity.
- Aadhaar: needed and must be linked to PAN; e-verification by Aadhaar OTP is the easiest way to complete filing.
- Bank account details: account number and IFSC of the account where you want any refund credited; pre-validate it on the portal.
- Last year's return (if any), which helps carry forward details and losses.
02Income proofs
Gather proof of every source of income for the year. What you need depends on how you earn.
| Income source | Document to keep |
|---|---|
| Salary | Form 16 from your employer; salary slips if needed |
| Bank and deposit interest | Interest certificates or bank statements; Form 16A for TDS |
| House property / rent | Rent received details and, for a home loan, the interest certificate |
| Capital gains (shares, mutual funds, property) | Broker or fund capital gains statement; sale and purchase documents for property |
| Business or profession | Books, profit and loss, and bank statements for the business |
| Other income | Dividend statements, pension details, winnings and similar records |
If you are salaried, your Form 16 is the backbone of the return. For a broader view of filing costs either way, see income tax return filing charges.
03Tax already paid: Form 26AS and AIS
Before you file, reconcile what the government already shows against your own records. Two statements matter:
- Form 26AS: your tax credit statement, showing TDS deducted, advance tax and self-assessment tax paid against your PAN.
- Annual Information Statement (AIS) and TIS: a wider statement of reported transactions, including interest, dividends, securities trades and some high-value spends.
Both are available on the e-filing portal at incometax.gov.in. Make sure the income and TDS in your return match these, because mismatches are a common reason for a later query. If something in the AIS is wrong, you can submit feedback on the portal.
Reconcile before you file
A quick check of Form 26AS and the AIS against your Form 16 and bank records catches missing TDS credit and unreported interest before filing, which is far easier than fixing it after a notice.
04Deduction and exemption proofs
If you claim deductions, keep the proofs. Note that many deductions apply mainly under the old regime, while the new regime offers fewer but a higher standard deduction. Common proofs include:
- Section 80C items: life insurance premiums, PPF, ELSS, children's tuition fees, principal on a home loan.
- Section 80D health insurance premium receipts.
- Home loan interest certificate for section 24(b).
- House rent details and rent receipts if you claim HRA.
- Donation receipts for section 80G, and education loan interest for section 80E.
Choosing the regime affects which of these actually reduce your tax, so it is worth comparing both before you file. For the form itself, see the income tax return form online.
05A note on keeping, not uploading
An important point that surprises first-time filers: for most returns you do not upload these documents to the portal. You use them to fill the figures, then keep them safely in case the department asks later. The return is filed on the numbers; the documents are your backup.
So the checklist is really about having everything in front of you while you file, and storing it afterward, rather than attaching files. Keep digital and physical copies for several years.
06How Claw Tax helps
Claw Tax and Accounts is an online tax, GST and accounting service for India that connects you with a verified chartered accountant at a fixed, published price, with a Claw reviewer checking every filing before it is submitted.
If you have a single salary, a Form 16 and no capital gains, you can gather these documents and file yourself for free on the portal, and that is the sensible route. Help is worth it when you have several income sources, capital gains, a regime choice to weigh, or mismatches in your AIS to sort out.
With Claw Tax and Accounts, you work to a clear document checklist, a verified chartered accountant prepares the return at a fixed published price, and a Claw reviewer checks it against your Form 26AS and AIS before filing. You approve the draft, and you get reminders before the next deadline.
This is not tax advice; a verified CA handles your specifics.
07Frequently asked questions
What documents do I need to file my income tax return?
At a minimum, PAN, Aadhaar linked to PAN, and bank details for a refund. Then income proofs such as Form 16 for salary, interest certificates, and capital gains statements. Then Form 26AS and the AIS to reconcile tax already paid. Finally, proofs for any deductions you claim, such as 80C and 80D.
Do I need to upload these documents on the portal?
For most returns, no. You use the documents to fill in the figures and then keep them as backup in case the department asks later. The return is filed on the numbers, not on attachments. Store digital and physical copies for several years.
What is the difference between Form 26AS and the AIS?
Form 26AS is your tax credit statement showing TDS, advance tax and self-assessment tax against your PAN. The Annual Information Statement is wider and lists reported transactions such as interest, dividends and securities trades. Reconcile both with your own records before filing to avoid mismatches.
What documents are needed if I have capital gains?
Keep the capital gains statement from your broker or mutual fund, which summarises buys, sells and gains, and for property, the sale and purchase deeds and related costs. These support the capital gains figures in your return, which usually means filing ITR-2 or ITR-3 rather than ITR-1.
Does the document list change if I use the new tax regime?
The income and tax-paid documents are the same. What changes is deduction proofs: the new regime allows fewer deductions but a higher standard deduction, so many 80C and similar proofs may not reduce your tax. Compare both regimes before filing to see which documents actually matter for you.
