Late ITR Filing Penalty Calculator — Section 234F & 234A (AY 2026-27)
Missed the ITR deadline? This calculator shows exactly what a late filing will cost you — the fixed Section 234F late filing fee (₹1,000 or ₹5,000 depending on income) and the Section 234A interest (1% per month on unpaid tax). Enter your details below to see your total additional cost before deciding when to file.
Section 234F: Late Filing Fee
Under Section 234F of the Income Tax Act, a fixed late filing fee is levied if you file your return after the applicable due date:
- ₹5,000 — if your total income exceeds ₹5,00,000
- ₹1,000 — if your total income is ₹5,00,000 or below
- Nil — if your income is below the basic exemption limit (₹3,00,000 new regime; ₹2,50,000 old regime for below 60)
This fee is automatically computed by the income tax portal when you file a belated return — you cannot waive it. It is a fixed fee, not an interest charge.
Section 234A: Interest on Unpaid Tax
Section 234A charges simple interest at 1% per month or part of a month on the amount of tax that remains unpaid after the due date. It runs from the day after the due date until the actual date of payment. Each partial month counts as a full month.
Key strategy: Pay any outstanding tax before the due date (via Challan 280 on incometax.gov.in) — this stops Section 234A interest from accruing even if you file the return later. Section 234F cannot be avoided once you file late, but Section 234A accrual can be stopped at any time by paying the tax.

Frequently Asked Questions
Can I avoid the Section 234F fee if I have a genuine reason for late filing?
No. Section 234F is a statutory fee with no provision for waiver based on individual circumstances. The only way to avoid it is to file on or before the applicable due date. Unlike some penalties, it does not require an assessing officer's order — it is levied automatically by the e-filing portal.
Is the Section 234F fee deductible from taxable income?
No. The Section 234F late filing fee is not deductible from your taxable income under any provision of the Income Tax Act. It must be paid in addition to your tax dues.
What if I have no tax payable — do I still pay Section 234F?
Yes, if your income exceeds the basic exemption limit. Section 234F applies based on income, not on whether tax is payable. For example, if your entire tax liability was covered by TDS (resulting in a refund), you still owe the Section 234F fee if you file late and your income exceeded the threshold. However, Section 234A interest does not apply if there is no unpaid tax.
Can a belated return be revised?
Yes. A belated return filed under Section 139(4) can be revised under Section 139(5) up to 31 December 2026 (the same date as the belated return deadline for AY 2026-27). You cannot revise a return filed after 31 December 2026.
