How Can I Avoid Penalties for Late Tax Filing?

If the return is very late and the normal filing window has already expired, there can be other options depending on the circumstances.

The Income Tax Department has a condonation of delay process under Section 119(2)(b) of the Income Tax Act, 1961 for certain situations involving genuine hardship, including eligible refund or loss-related claims. The Department's current guidance says taxpayers can submit a condonation request through the e-Filing portal, along with the relevant return and supporting documents.

But I wouldn't assume that simply having forgotten the deadline automatically qualifies for condonation.

If you're still within the belated-return period, filing the return normally may be the more relevant route. If you're already outside that period, check whether ITR-U or a condonation request is applicable to your particular case.

I had a similar situation and initially thought that an “updated return” was simply another name for a belated return.

They're not the same thing.

A belated return is used when you missed the original filing deadline but are still within the permitted belated-filing period.

An updated return (ITR-U) is a separate mechanism for reporting income that wasn't correctly reported earlier, subject to the conditions and additional tax applicable to an updated return.

For tax years beginning on or after April 1, 2026, the new Income Tax Act, 2025 provides for belated returns under Section 263(4), with the belated-return period being within nine months from the end of the relevant tax year or before completion of assessment, whichever is earlier. The delayed-filing fee under the new Act remains ₹1,000 or ₹5,000, depending on total income.

So I wouldn't choose ITR-U simply because the original deadline was missed.

If you've only missed the original due date, don't assume that you have to wait for a notice.

For AY 2026–27, the Income Tax Department says a belated return can generally be filed under Section 139(4) up to 31 December 2026, or before completion of assessment, whichever is earlier. The late-filing fee under Section 234F is ₹1,000 where total income does not exceed ₹5 lakh and ₹5,000 in other cases.

There can also be interest if tax was payable, so the total amount isn't necessarily limited to the late-filing fee.

I'd suggest preparing the return as soon as possible rather than delaying further. Check your AIS, Form 26AS, bank interest, rental income and TDS before submitting it.

Also make sure you complete e-verification after filing. The Income Tax Department currently gives 30 days for e-verification or submission of ITR-V.
