ITR Filing 2026-27: Check These 9 Important Points Before Filing Your Income Tax Return

By Siddhi Jain | Jun 11, 2026, 17:05 IST

Income Tax Return (ITR): The ITR filing season for Assessment Year 2026-27 has begun. While many taxpayers still consider ITR filing as a formality or a way to claim a tax refund, the process has become much more important today. The Income Tax Department now receives financial data directly from banks, employers, mutual funds, stock brokers, and various financial institutions. As a result, even a small mistake in your return can lead to notices, tax demands, penalties, or delays in refunds.

Before filing your ITR, make sure you review these nine important points carefully.

1. Choose the Correct ITR Form

Selecting the right ITR form is the first and most important step.

The applicable form depends on factors such as:

Salary income
Business or professional income
Capital gains
Foreign assets or income
Rental income

Using the wrong form may result in your return being treated as defective or invalid, forcing you to file again.

2. Reconcile AIS, Form 26AS and Form 16

Before filing, compare the details available in:

Form 16
Form 26AS
AIS (Annual Information Statement)
TIS (Taxpayer Information Summary)
Pre-filled ITR data

Any mismatch in income, TDS, interest earnings, investments, or tax payments should be corrected beforehand to avoid future scrutiny.

3. Report All Sources of Income

Many taxpayers report only their salary income and overlook other earnings.

Make sure to disclose:

Savings account interest
Fixed Deposit interest
Rental income
Freelancing income
Capital gains
Dividend income
Any other taxable receipts

Failure to report income can trigger notices from the Income Tax Department.

4. Mention Tax-Free Income as Well

Even if certain income is exempt from tax, it should still be disclosed in the return.

Examples include:

Gratuity
Leave encashment
Commuted pension
Certain exempt allowances

Reporting tax-free income ensures consistency between your financial records and tax filings.

5. Claim Only Genuine Deductions

Claim deductions under Sections such as:

80C
80D
80CCD
80G
80TTA/80TTB

Only if you are genuinely eligible and possess supporting documents.

Incorrect deduction claims may lead to:

Additional tax liability
Interest charges
Penalties
Tax notices

6. Verify Your Bank Account Details

If you are expecting a tax refund, ensure that:

Your bank account is pre-validated on the Income Tax portal.
Account number and IFSC code are correct.
The account is active.

Incorrect banking details can delay or block your refund.

7. Review the Entire Return Before Submission

Before clicking the final submit button, double-check:

Name and PAN details
Address
Mobile number
Email ID
Income details
TDS information
Tax payments
Bank account details

A simple data-entry error can create unnecessary complications later.

8. File Your ITR Before the Due Date

Do not wait until the last day.

For most individual taxpayers, the due date for AY 2026-27 is 31 July 2026.

Late filing may result in:

Late filing fees
Interest on outstanding tax
Delay in refunds
Loss of certain tax benefits

Timely filing also provides sufficient time to correct any mistakes.

9. Complete ITR Verification

Filing the return is only half the process.

After submission, the return must be verified within the prescribed time limit through:

Aadhaar OTP
Net Banking
Demat account verification
Bank account verification
Physical ITR-V submission (where applicable)

If verification is not completed, the Income Tax Department may treat the return as invalid.
