ITR Filing Deadline: What happens if you miss the August 31 ITR deadline? How can you file your return after that?

If you haven't filed your ITR yet, you have only a few days left. For certain taxpayers, the deadline to file the ITR for the Assessment Year 2026-27 is August 31, 2026. Filing your return on time helps you avoid late fees and interest on outstanding tax dues.

Missing the August 31 deadline does not mean it is the end of the road. You can still file a 'belated ITR' until December 31, 2026. However, you may have to pay a late fee. Additionally, in some cases, you might lose the benefit of carrying forward tax losses to future years.

The August 31 deadline applies to taxpayers required to file ITR-3, ITR-4, ITR-5, or ITR-7. This includes individuals with income from a business or profession whose accounts do not require a tax audit.

What happens if you miss the August 31 deadline?

Missing the deadline does not mean you cannot file an ITR at all. You can file a belated return up to December 31, 2026. However, if your assessment is completed before that date, you will no longer be able to file the return.

Filing an ITR late also attracts a late fee. If your total income exceeds ₹5 lakh, the late fee can be up to ₹5,000. For those with a total income of up to ₹5 lakh, the fee is ₹1,000.

If you have outstanding tax dues, interest may be charged at a rate of 1% per month (or part thereof). This interest is levied under Section 234A of the Income Tax Act.

Will you get a refund if you file the ITR late?

Yes, missing the deadline does not forfeit your right to a tax refund. If you are entitled to a refund, you can claim it by filing a belated return by December 31, 2026. However, verifying the return after filing it is mandatory. The Income Tax Department allows a 30-day window for e-verification. The refund process will only proceed once the return has been verified.

**Difficulty in Adjusting Losses**

Filing an ITR after the deadline can result in a significant disadvantage, particularly regarding the carry-forward of losses. Suppose you have incurred losses in business, the stock market, or F&O trading; you could save on taxes by offsetting these losses against future earnings. However, if you fail to file your ITR on time, you may lose the benefit of carrying forward certain types of losses.

In other words, it is not merely a matter of paying a late fee; filing a delayed ITR could also mean missing out on future tax-saving opportunities.

**What to do if there is an error in the ITR?**

If you discover an error or realize that some information was omitted after filing your ITR, you can file a revised return under Section 139(5).

Generally, a revised return for the Assessment Year 2026-27 can be filed up to March 31, 2027. However, this option may no longer be available if the assessment is completed before that date. Once a revised return is filed, it replaces the original return and must also be verified.

Do keep in mind, however, that filing a revised return does not restore tax benefits that were already lost due to the initial delay in filing the ITR. This includes the benefit of carrying forward certain types of losses.
