Documents Needed to File ITR in 2026: Form 16, AIS, Form 26AS and More

Filing your Income Tax Return becomes much easier when your documents are ready before you start.

The problem is that most people open the ITR filing flow first, then realise they need Form 16, AIS, Form 26AS, bank details, investment proofs or capital gains statements.

So before you file your ITR for FY 2025-26 / AY 2026-27, here is a simple checklist of documents you should keep ready.

Here are the key documents and details you may need while filing your ITR:

1. PAN

PAN is one of the most important details needed for ITR filing.

Your PAN is used to identify your tax records, income details, TDS, refunds and other information linked to you.

Make sure your PAN details are correct before you start filing.

2. Aadhaar

Aadhaar may be required for verification and identity-related checks while filing your ITR.

You should also make sure your Aadhaar and PAN are linked where required.

If your basic identity details do not match, filing and verification can become unnecessarily painful.

3. Form 16

Form 16 is one of the most important ITR documents for salaried employees.

It is issued by your employer and usually contains:

• Salary details

• Tax deducted from salary

• Employer details

• Employee PAN

• Employer TAN

• Exemptions

• Deductions

• Taxable salary

• Tax payable details

But remember, Form 16 is not your full ITR.

It is a key salary and TDS document, but you still need to check AIS and Form 26AS before filing.

4. AIS

AIS stands for Annual Information Statement.

Think of it as a wider view of financial information reported against your PAN.

AIS can include details such as:

• TDS

• TCS

• Interest income

• Dividends

• Securities transactions

• Mutual fund transactions

• Tax payments

• Refunds

• Certain high-value financial transactions

Before filing your ITR, check whether the income and tax details in AIS match your own records.

If something looks wrong, do not ignore it.

A mismatch can create issues later.

5. Form 26AS

Form 26AS is your tax credit statement.

It helps you check details such as:

• TDS

• TCS

• Advance tax

• Self-assessment tax

• Refunds

• Certain tax-related details linked to your PAN

If TDS has been deducted from your salary, bank interest or other income, Form 26AS helps you cross-check whether the tax credit is visible.

This is important because your ITR should correctly claim credit for the tax already deducted or paid.

6. TIS

TIS stands for Taxpayer Information Summary.

It gives a simplified summary of taxpayer information based on AIS.

You may not use it as heavily as AIS or Form 26AS, but it can help while reviewing the details already available with the tax department.

7. Bank account details

You need to provide correct bank account details while filing ITR.

This is especially important if you are expecting an income tax refund.

Make sure you check:

• Account number

• IFSC code

• Bank name

• Account status

• Pre-validation status, if applicable

Wrong bank details can delay your refund.

8. Salary slips

If you are salaried and your Form 16 is not available or you want to cross-check your salary breakup, salary slips can help.

They may include:

• Basic salary

• HRA

• Allowances

• Deductions

• Professional tax

• Employer contributions

• Monthly TDS

Salary slips are also useful if you need to verify whether the details in Form 16 are correct.

9. Interest certificates and bank statements

Interest income is easy to forget.

But the tax department may already have details of interest income through AIS or other reporting sources.

Keep details ready for:

• Savings account interest

• Fixed deposit interest

• Recurring deposit interest

• Other bank interest income

You can use interest certificates and bank statements to verify the correct amount before filing.

10. Investment and deduction proofs

If you are claiming deductions under the old tax regime, keep your investment and deduction proofs ready.

These may include:

• Life insurance premium receipts

• ELSS investment proof

• PPF proof

• EPF details

• Health insurance premium receipts

• Home loan repayment proof

• Education loan interest certificate

• Donation receipts, if applicable

• Other eligible deduction documents

Do not randomly claim deductions without proof.

If a claim is questioned later, you should be able to support it.

11. Rent receipts and HRA documents

If you are claiming HRA, keep rent-related documents ready.

You may need:

• Rent receipts

• Rent agreement, if available

• Landlord PAN, where required

• Payment proof, if available

If your HRA claim was already considered by your employer, it may reflect in your Form 16.

Still, keep your documents safely stored.

12. Home loan documents

If you are claiming home loan benefits, keep these ready:

• Home loan interest certificate

• Principal repayment details

• Property details

• Co-owner details, if applicable

• Rent or self-occupied property details, depending on your case

Home loan claims can affect your tax calculation, especially under the old tax regime.

13. Capital gains statement

If you sold investments during the financial year, you may need capital gains details.

This can include:

• Mutual fund capital gains statement

• Stock transaction statement

• Broker statement

• Digital gold sale records

• Property sale documents, if applicable

• Other asset sale records

Capital gains can affect which ITR form you need to file.

If you have capital gains, do not blindly file a simple return without checking your form eligibility.

14. Digital gold transaction records

If you bought or sold digital gold during the financial year, keep your transaction records ready.

Buying gold may not be the issue.

Selling gold is where tax treatment can matter.

You may need to check:

• Date of purchase

• Date of sale

• Quantity sold

• Sale value

• Purchase value

• Gain or loss, if any

• Holding period

Gold taxation can depend on your holding period, gain amount and overall income situation.

Spare8 users who are unsure about digital gold taxation can file through ClearTax and access expert/CA-assisted filing options where applicable, especially if they have capital gains or complex income situations.

15. Details of other income

Apart from salary, many people also earn income from other sources.

This can include:

• Interest income

• Freelance income

• Rental income

• Dividend income

• Capital gains

• Side income

• Business or professional income

Do not assume that only salary matters.

Your ITR should include all applicable income details.

16. Previous year’s ITR

Your previous year’s ITR may be useful for reference.

It can help you check:

• Personal details

• Bank details

• Income pattern

• Deduction history

• Carried forward losses, if any

• Filing consistency

This is not always mandatory, but it can help avoid mistakes.

Are ITR forms annexure-less?

Yes, ITR forms are generally annexure-less.

This means you usually do not attach supporting documents like Form 16, rent receipts, investment proofs or bank statements while filing your ITR.

But that does not mean the documents are useless.

You should keep them ready while filing and store them safely after filing.

If there is any mismatch, query or future check, these documents can help support your return.

Why checking AIS and Form 26AS matters

Before you submit your ITR, check AIS and Form 26AS carefully.

This helps you verify:

• Whether TDS is visible

• Whether interest income is reported

• Whether tax payments are recorded

• Whether refunds are shown correctly

• Whether your income details match your records

If something is missing or incorrect, it is better to catch it before filing.

Not after.
