Penalty for Late Filing of Income Tax Return
Miss your ITR due date and two charges hit automatically — a flat late fee, plus interest that grows every month. Here is exactly what you pay for AY 2026-27, worked through with real numbers, and how to keep it to zero.
The penalty for late filing of income tax return is a flat fee of ₹5,000 under Section 234F — reduced to ₹1,000 if your total income is up to ₹5 lakh — plus 1% per month interest under Section 234A on any unpaid tax. The fee applies the day after your ITR due date passes.
Section 234F — the flat penalty
234F is a fixed fee for filing after the due date, charged regardless of whether you owe any tax. The amount depends only on your total income.
Total income above ₹5 lakh
The standard late fee for most filers who miss the due date.
Total income up to ₹5 lakh
A reduced fee for small taxpayers.
Income below the basic exemption limit
No 234F fee if you were not otherwise required to file (see note).
The basic exemption limit is ₹4 lakh under the new regime for FY 2025-26. If your income is below it and filing was not mandatory for another reason (foreign assets, high-value deposits, etc.), no 234F applies. If filing was mandatory, the fee can still apply.
Section 234A — interest on unpaid tax
On top of the flat fee, 234A charges interest on any tax you still owe — for every month you delay filing.
Simple interest on the unpaid self-assessment tax.
Even one day into a new month counts as a full month.
From the day after your due date until you actually file.
234A runs only on tax that is still unpaid. If your tax is fully covered by TDS and advance tax, 234A is nil — but the 234F flat fee can still apply for filing late.
What late filing actually costs — two examples
The fee and interest stack. Here is how they add up in practice.
Salaried, income ₹9,00,000
Files 3 months late, ₹30,000 tax unpaid
Small taxpayer, income ₹4,50,000
Files 2 months late, ₹2,000 tax unpaid

234B & 234C — advance-tax interest
If you owe ₹10,000+ in tax for the year, these can apply even before the filing deadline — another reason late filing rarely travels alone.
Default in advance tax
1% per month where you paid less than 90% of your tax as advance tax, from 1 April of the assessment year until you pay.
Deferred instalments
1% per month for shortfalls in the quarterly advance-tax instalments (15 Jun / Sep / Dec / Mar).
The penalties you can't see on a challan
The 234F fee is the visible cost. These hidden ones often hurt a growing business more.
Loss carry-forward is lost
Capital and business losses can't be carried forward to cut future tax. Only house-property loss and unabsorbed depreciation survive.
Refund and its interest delayed
A late return is processed later, so your refund — and the interest on it — arrives later.
Old regime can be locked out
For business or professional income, Form 10-IEA must be filed by the due date to keep the old regime. Compare both first with the income tax calculator.
How to avoid (or reduce) the penalty
File before the due date
The only way to pay ₹0. Know your date — 31 July, 31 August or 31 October — and treat it as final.
File my ITR now →If you've missed it, file the belated return today
234A interest keeps running each month you wait. Filing now stops the clock and caps the damage at 31 December 2026.
File a belated return →Pay your self-assessment tax immediately
234A and 234B run on unpaid tax. Paying the tax now stops the interest even before you file.
Calculate what I owe →Get the return right the first time
A wrong form or missed deduction can mean revising later. A CA files it correctly, on time, the first time.

Late-filing penalty — FAQs
What is the penalty for late filing of income tax return?
A late fee of ₹5,000 under Section 234F (reduced to ₹1,000 if total income is up to ₹5 lakh), plus 1% per month interest under Section 234A on any unpaid tax, from the day after the due date until you file.
Is there a penalty if I have no tax due?
The 234A interest is nil if no tax is unpaid, but the flat 234F fee can still apply for filing after the due date when filing was required.
What if my income is below the basic exemption limit?
If your income is below the basic exemption limit (₹4 lakh under the new regime for FY 2025-26) and you were not otherwise required to file, no 234F fee applies. If filing was mandatory for another reason, it can.
Can the late-filing penalty be waived?
234F is a fixed statutory fee with no general waiver. The best you can do is file early to avoid it, or file a belated return quickly to stop 234A interest from growing.
How is 234A interest calculated?
1% of the unpaid tax for each month or part of a month of delay. Even one day into a new month counts as a full month.
Can a CA help reduce what I pay?
Yes. A CA ensures the right tax is computed, the correct regime and deductions are claimed, and the return is filed on time — the surest way to keep the penalty at zero.
Zero penalty starts with filing on time
Don't let a missed date cost you ₹5,000 and growing interest. Send your documents on WhatsApp — a CA picks the right ITR, claims every deduction, and files before your deadline.
