Section 234F Late Fee + 234A Interest on a Belated Return: Worked Examples
- Filing after 31 July 2027 costs you ₹1,000–₹5,000 as a flat late fee under Section 234F, plus interest on any unpaid tax under Section 234A.
- Section 234F is a fee (unavoidable once you miss the deadline); Section 234A is interest (avoidable if you pay all tax before the due date).
- Paying your full tax liability before 31 July eliminates 234A interest even if you file the return late.

If you miss the 31 July 2027 deadline for FY 2026-27 (AY 2027-28), two charges can hit your bank account simultaneously: a flat late-filing fee under Section 234F and monthly interest under Section 234A. The good news is they work differently — one is inevitable once you are late, the other is entirely avoidable. This article shows you the exact maths with real rupee figures so you know what you owe before you file.
Section 234F: The Flat Late-Filing Fee
Section 234F was introduced from AY 2018-19 onwards. It imposes a fee — not a penalty, a fee — simply for filing your ITR after the due date. The amount depends on two things: when you file and how large your total income is.
| When you file (for AY 2027-28) | Total income ≤ ₹5,00,000 | Total income > ₹5,00,000 |
|---|---|---|
| On or before 31 July 2027 (due date) | Nil | Nil |
| 1 August 2027 – 31 December 2027 | ₹1,000 | ₹5,000 |
| 1 January 2028 – 31 March 2028 | ₹1,000 | ₹5,000 |
Key points:
- The ₹5,000 cap does not increase — it is the same whether you file in August or in March.
- If your total income is below the basic exemption limit (currently ₹3,00,000 under the old regime or ₹4,00,000 under the new regime for individuals below 60), you are technically not required to file and Section 234F does not apply.
- The fee is self-assessed — you pay it through Challan 280 before submitting your return. The portal calculates it automatically.
Section 234A: Monthly Interest on Unpaid Tax
Section 234A charges interest at 1% per month (or part of a month) on the tax payable after TDS/TCS/advance tax credits, calculated from the day after the due date until the date of filing. This is simple interest, not compound.
The critical word is "unpaid." If your TDS has already covered your entire tax liability, your Section 234A interest is zero — even if you file six months late.
Worked Example 1: Salaried Person, Income ₹12,00,000 (New Regime)
Ravi works as a software engineer. His details for FY 2026-27:
- Gross salary: ₹12,00,000
- Tax payable (new regime, after standard deduction of ₹75,000): approximately ₹83,200 (including 4% cess)
- TDS deducted by employer: ₹83,200
- He files his return on 15 September 2027 — 46 days late.
Section 234F calculation: Total income > ₹5,00,000 and filed after 31 July 2027 → ₹5,000 flat fee.
Section 234A calculation: Tax payable after TDS = ₹83,200 − ₹83,200 = ₹0. Interest = 1% × ₹0 × 2 months = ₹0.
Total extra cost: ₹5,000. Ravi pays only the 234F fee because his employer deducted the full tax. This is the most common scenario for salaried taxpayers with accurate TDS.
Worked Example 2: Freelancer with Shortfall, Income ₹18,00,000
Priya is a freelance designer. Her details for FY 2026-27:
- Net taxable income: ₹18,00,000 (new regime)
- Tax payable (including cess): approximately ₹2,08,000
- Advance tax and TDS collected: ₹1,60,000
- Balance tax unpaid: ₹48,000
- She files on 20 February 2028 — about 6 months and 20 days after the 31 July due date.
Section 234F: Income > ₹5,00,000, filed after 31 December 2027 → ₹5,000.
Section 234A: The period runs from 1 August 2027 to 20 February 2028. That is 7 months (part months count as full months: August, September, October, November, December, January, February = 7 months).
Interest = ₹48,000 × 1% × 7 = ₹3,360.
Total extra cost: ₹5,000 + ₹3,360 = ₹8,360.
Had Priya paid the ₹48,000 balance tax via self-assessment challan on or before 31 July 2027 (even without filing the return), her 234A interest would have dropped to zero. She would have owed only the ₹5,000 234F fee.
How to Reduce Your Total Outgo: The Split Strategy
- Pay all outstanding tax by 31 July. Go to the income-tax portal, compute your liability roughly, and pay via Challan 280 (code 300 — self-assessment tax). This cuts 234A to zero.
- File as early as possible after that. The 234F fee is fixed once you cross 31 July, so there is no additional financial benefit in waiting, but filing promptly closes the assessment year cleanly.
- Use the correct ITR form. Filing the wrong form can lead to a defective return notice, effectively restarting the clock on penalties.
KyaTax's ITR wizard automatically selects your form, prefills TDS data from Form 26AS, and shows your live 234F and 234A liability before you submit.
Common Mistakes People Make
- Mistake 1 — Confusing 234F with a penalty. Many people think they can "appeal" or "waive" the 234F fee. You cannot. It is a statutory fee payable as part of self-assessment tax. Only in genuine hardship cases can the CBDT consider relief, but routine late filers should assume it is payable.
- Mistake 2 — Ignoring the ₹5,00,000 threshold. A person with income of ₹5,10,000 pays ₹5,000 in 234F; a person with ₹4,90,000 pays only ₹1,000. If you are close to the threshold, verify your total income after all deductions — not your gross salary.
- Mistake 3 — Thinking TDS = no 234A liability. TDS covers salary income well, but if you also have rental income, capital gains, or interest on which no TDS was deducted, a shortfall can exist. Always check Form 26AS and AIS together.
- Mistake 4 — Counting 234A months incorrectly. The statute counts "months or part thereof." Filing on 1 August counts as one full month. Filing on 31 August also counts as one full month. Day 1 of any new month triggers a fresh monthly charge.
- Mistake 5 — Waiting for Form 16 before even estimating tax. Employers must issue Form 16 by 15 June. If yours is delayed, estimate from your salary slips and pay advance/self-assessment tax to avoid 234A running. You can always reconcile when Form 16 arrives.

Open ITR wizard →Frequently asked questions
What is the maximum Section 234F late fee for FY 2026-27?
The maximum is ₹5,000. This applies to anyone with total income above ₹5,00,000 who files after 31 July 2027. If your total income is ₹5,00,000 or below, the fee is capped at ₹1,000 regardless of how late you file.
Can I avoid Section 234A interest even if I file late?
Yes. Section 234A interest accrues only on the tax that remains unpaid after the due date. If you deposit the entire balance tax via self-assessment challan (Challan 280) on or before 31 July 2027, your 234A interest is zero — even if you file the actual return months later.
Is the 234F fee applicable if my income is below the taxable limit?
No. If your gross total income is below the basic exemption limit applicable to you (which means no tax is payable and you are not otherwise required to file), Section 234F does not apply. However, if you are required to file due to other conditions — such as foreign assets, high-value transactions, or TDS refund claims — the fee can still apply depending on your income level.
Does filing a belated return affect my ability to carry forward losses?
Yes, this is a significant consequence that goes beyond fees. If you file a belated return under Section 139(4), you lose the right to carry forward most losses — particularly capital losses and business losses — to future years. Losses from house property are an exception and can still be carried forward. This makes timely filing important even when the monetary fee seems small.
