ITR Filing After Due Date: Late Filing Fee, Procedure & Belated ITR

Can I File ITR After the Due Date?

Yes, in many cases you can file your return after the original due date. This is generally called a Belated ITR. For AY 2026–27, a belated return may be furnished on or before 31 December 2026, or before completion of assessment, whichever is earlier.

Returns relating to FY 2025–26 / AY 2026–27 continue to be governed by the Income-tax Act, 1961. Select the correct Assessment Year, ITR form and filing category before submission.

What Is a Belated ITR?

A Belated ITR is an Income Tax Return filed after the original due date but within the period permitted by law. For AY 2026–27 it is filed under Section 139(4) of the Income-tax Act, 1961.

Last Date and Late Filing Fee

For AY 2026–27, the current deadline for a belated return is 31 December 2026 or completion of assessment, whichever is earlier. Deadlines can differ by assessment year, so always check the applicable year before filing.

The late filing fee is separate from income tax and interest. Depending on the facts, the amount due may include tax payable, applicable interest and the late filing fee.

How to File ITR After the Due Date

1. Identify the correct Assessment Year

Match the financial year in which income was earned to the correct Assessment Year. For example, income earned during FY 2025–26 is reported in AY 2026–27.

2. Collect and reconcile your records

• PAN and Aadhaar
• Form 16 and Form 16A
• Form 26AS, AIS and TIS
• Bank statements and interest certificates
• Salary, rent, capital gains and other income records
• Business or professional accounts
• Deduction documents
• TDS, TCS, advance-tax and self-assessment-tax challans

Compare tax credits claimed in the return with Form 26AS. Review AIS and TIS for salary, interest, dividends, securities, mutual funds, property and other reported transactions, and investigate material differences before filing.

3. Select the correct ITR form

Choose from ITR-1 to ITR-7 according to your taxpayer status and income profile. Do not select a form only because you used it in an earlier year.

4. Compute income and tax

Calculate income under salary, house property, business or profession, capital gains and other sources. Then account for the applicable tax regime, slabs, rebate, surcharge, cess, permitted deductions, TDS, TCS, advance tax, interest and late filing fee.

5. Pay any balance and file under Section 139(4)

Pay any additional tax shown by the computation, retain the challan details, and select the option indicating that the return is being filed as a Belated Return under Section 139(4).

6. E-verify the return

Complete verification through Aadhaar OTP, eligible bank or demat EVC, net banking, Digital Signature Certificate or ITR-V, as applicable. The current verification period is 30 days from filing. Delayed verification can change the effective filing date and trigger late-filing consequences.

What Happens When You File Late?

• Late filing fee under Section 234F may apply
• Interest may be charged where tax remains unpaid
• Carry-forward of certain business, professional and capital losses may be restricted
• Processing and any eligible refund may be delayed
• Other consequences may apply depending on your facts

An eligible refund may still be claimed through a late return, and a return may still be required even when no additional tax is payable. Zero tax payable does not automatically mean that filing is unnecessary.

If the Belated Return Deadline Has Passed

Updated Return (ITR-U)

An Updated Return under Section 139(8A) is a separate mechanism with its own eligibility conditions, time limit, restrictions and additional-tax requirements. It cannot generally be used to increase a refund and should not be treated as a simple replacement for a belated return.

Condonation of delay

In genuine-hardship cases, relief may be sought under Section 119(2)(b), subject to the applicable requirements and approval by the competent authority. Condonation is not an automatic extension of the filing deadline.

Frequently Asked Questions

Can a Belated ITR be revised?

A belated return may generally be revised where the applicable law permits and the statutory deadline has not expired.

Can I claim a refund after filing late?

An eligible taxpayer may claim a refund through the return, subject to the applicable provisions. Filing earlier can help the processing and refund lifecycle begin sooner.

What if I have a business or capital loss?
