Late Filing Fee Calculator — Section 234F

Quick answer

If you file your income tax return after the due date, Section 234F charges a late filing fee of ₹5,000. If your total income is ₹5 lakh or less, the fee is capped at ₹1,000. If your income is below the basic exemption limit and you were not otherwise required to file, no fee applies. The fee is a fixed amount, it does not grow month by month, and it is separate from any interest on unpaid tax.

What the Section 234F late fee actually is

Section 234F is a flat fee for missing the return due date. It is not a penalty that an officer decides after a hearing, and it is not interest. Once the due date has passed and you are a person who has to file, the fee becomes payable automatically when you file a belated return.

Because it is fixed, it does not matter whether you file one day late or four months late. Filing on 1 August instead of 31 July costs the same fee as filing on 20 December. What does grow with time is the interest on any tax you still owe, which is charged separately under Section 234A.

The fee was brought in to push people to file on time. In practice it hits two groups most often: salaried people who think they have "nothing to pay" because TDS covers their tax, and small business owners who wait for their accounts to be finalised and then miss the date.

Which due date makes you "late"

The fee is linked to the due date under Section 139(1) that applies to you. For most salaried individuals and pensioners who do not need a tax audit, this has traditionally been 31 July of the assessment year. Taxpayers whose accounts must be audited have a later due date, and some special cases have later dates still. The department also extends due dates from time to time by notification.

So always use the date that applies to your category for that particular year, including any extension. If the date was extended and you filed within the extended date, you are not late and no 234F fee applies. The belated return deadline, normally 31 December of the assessment year, is a separate date; filing between the due date and that deadline is what attracts the fee.

A note on the new law: the Income-tax Act, 2025 applies from 1 April 2026 and uses the term "tax year". From tax year 2026-27 the new Act renumbers sections such as 234F, 234A and 87A. This calculator uses the familiar section numbers and follows the fee amounts shown here.

How to use this late filing fee calculator

The calculator asks for five things. Each one matters, so here is what to enter and why.

1. Total income for the year — enter your total income after deductions such as 80C and 80D (in the old regime), not your gross salary. This figure decides whether the fee is ₹1,000 or ₹5,000.
2. Tax regime — choose the new regime (the default) or the old regime. The regime decides your basic exemption limit, which the calculator uses to check whether any fee applies at all.
3. Your age — only relevant for the old regime, where the exemption limit is ₹2.5 lakh below 60, ₹3 lakh for senior citizens (60 to 79) and ₹5 lakh for super senior citizens (80 and above). In the new regime the limit is ₹4 lakh for everyone.
4. Your due date — the due date that applies to you for that year. For most salaried individuals this is 31 July of the assessment year, unless the department extends it. If you are not sure, use our ITR due date checker.
5. Date you filed / will file — the actual or planned filing date.

The result shows whether a fee applies, the fee amount, how many months late you are, and a warning if your filing date falls after 31 December, when the belated return window normally closes.

The rule in one table

The calculator follows this logic exactly. "Total income" here means income after deductions, as you enter it.

Basic exemption limits the calculator uses

How "total income" is worked out for the ₹5 lakh test

The ₹1,000 cap depends on total income, so it helps to know how that figure is built. Start with all your income for the year: salary after the standard deduction, rent after the 30% deduction and any home-loan interest allowed, business or professional profit, capital gains, and interest and other income. In the old regime, you then subtract Chapter VI-A deductions such as 80C, 80D and 80CCD(1B). In the new regime, most of these deductions are not available, so total income stays closer to gross income.

Take a salaried person with a gross salary of ₹5,40,000 and ₹20,000 of savings interest. In the new regime, total income is ₹5,40,000 − ₹75,000 + ₹20,000 = ₹4,85,000, so a late return costs ₹1,000. In the old regime, with ₹50,000 standard deduction, ₹1,50,000 in 80C and ₹10,000 under 80TTA, total income is ₹3,50,000 and the fee is still ₹1,000, because it is above the ₹2.5 lakh limit. Capital gains count in total income too, even though they are taxed at special rates.

Notice the gap in the new regime. The Section 87A rebate makes tax nil for taxable income up to ₹12 lakh, but the exemption limit is still ₹4 lakh. So a person earning ₹9 lakh who pays zero tax must still file, and still pays ₹5,000 if they file late. This is the single most common surprise we see with 234F.

Worked examples with real numbers

Example 1: Salaried, zero tax, filed late

Neha earns a salary of ₹9,50,000 and stays in the new regime. After the ₹75,000 standard deduction, her total income is ₹8,75,000. Her tax is nil because of the 87A rebate, and her employer deducted no TDS. Her due date was 31 July 2026, and she files on 20 September 2026.

• Filed after the due date: yes.
• Income ₹8,75,000 is above the ₹4 lakh exemption limit: fee applies.
• Income is more than ₹5 lakh: fee is ₹5,000.

Neha owes no tax, so there is no 234A interest. But the ₹5,000 fee must be paid before she can submit the belated return. Zero tax does not mean zero obligation.

Example 2: Small income, ₹1,000 fee

Ramesh, aged 45, has interest and freelance income. His total income in the new regime is ₹4,60,000. He files on 15 October 2026 against a 31 July due date.

• Income ₹4,60,000 is above ₹4 lakh: fee applies.
• Income is not more than ₹5 lakh: fee is ₹1,000.

If Ramesh had chosen the old regime with the same ₹4,60,000 total income, the exemption limit would be ₹2.5 lakh and the fee would still be ₹1,000.

Example 3: Income below the exemption limit

Kamla, aged 68, has pension and FD interest. Her total income is ₹3,80,000 in the new regime. She files late only to claim a refund of TDS deducted by her bank.

• Income ₹3,80,000 is below the ₹4 lakh new-regime limit.
• Fee: Nil, provided she was not required to file for any other reason.

She can still file a belated return and claim her refund, without paying any late fee.

Example 4: Filing after 31 December

Arjun, with income of ₹14 lakh, forgets to file and remembers in February 2027. If he enters a filing date after 31 December 2026, the calculator shows the ₹5,000 fee and also warns that the belated return window has closed. At that stage only an updated return (ITR-U) is possible, which comes with additional tax on top of the tax and interest. This is a different and costlier route, covered further below.

Example 5: Fee plus interest for a freelancer

Sameer is a freelance designer with total income of ₹11 lakh. His tax for the year after rebate and cess works out to ₹90,000, and clients deducted ₹20,000 as TDS. He paid no advance tax. His due date was 31 July 2026 and he files and pays the balance on 10 October 2026.

• Late fee under 234F: income above ₹5 lakh, so ₹5,000.
• Tax still payable: ₹90,000 − ₹20,000 = ₹70,000.
• 234A interest: August, September and October = 3 months × 1% × ₹70,000 = ₹2,100.
• 234B interest (no advance tax paid): April to October = 7 months × 1% × ₹70,000 = ₹4,900.
• 234C interest for missed instalments: ₹3,535 (as the interest calculator shows).

His total extra cost is ₹5,000 + ₹2,100 + ₹4,900 + ₹3,535 = ₹15,535 on top of the ₹70,000 tax. Only ₹5,000 of that is the late fee; the rest came from not paying tax on time. If Sameer had at least filed and paid by 31 July, the fee and the 234A part (₹7,100 together) would have been avoided.

When the fee applies even below the exemption limit

The calculator treats income up to the exemption limit as "no fee", which is right for most people. But the law makes filing compulsory for some people even when their income is low. If you fall in one of these groups, you are a person required to file, and a late return can attract the fee.

Filing is compulsory, irrespective of income, in cases such as:

• you deposited more than ₹1 crore in one or more current accounts during the year;
• you spent more than ₹2 lakh on foreign travel for yourself or another person;
• you paid electricity bills of more than ₹1 lakh during the year;
• you hold assets outside India, or have signing authority in a foreign account, as a resident;
• other conditions notified by the department, for example based on business turnover, professional receipts, TDS/TCS amount or savings account deposits.

Also note that, for checking whether filing is compulsory, the department looks at income before Chapter VI-A deductions like 80C and 80D. So if your gross income is ₹3.2 lakh and 80C brings it down to ₹2.2 lakh in the old regime, you were still required to file because ₹3.2 lakh is above the ₹2.5 lakh limit. Enter your figures carefully and, if you are near the line, ask an expert.

NRIs and the age-based limits

The higher old-regime exemption limits of ₹3 lakh and ₹5 lakh for senior and super senior citizens are available only to residents. A non-resident aged 65 using the old regime has a ₹2.5 lakh limit, not ₹3 lakh. If you are an NRI, choose "Below 60" in the age field when you test the old regime, so the calculator uses the correct limit. The ₹1,000 and ₹5,000 fee amounts are the same for residents and non-residents.

234F fee versus 234A interest

People often mix these two up. They are charged together when you file late with tax unpaid, but they work very differently.

So if you have tax to pay, the true cost of delay is the fee plus the monthly interest. Run your numbers in our 234A, 234B and 234C interest calculator to see the full amount. If tax is fully covered by TDS and advance tax, the fee is your only cost.

What else you lose by filing late

The fee is the visible cost. A belated return also has some quieter costs that matter more for some people.

You cannot choose the old regime

For individuals without business income, the option to use the old regime has to be exercised in a return filed on or before the due date. File late and you are taxed under the new regime. If your HRA, 80C, 80D and home-loan interest made the old regime cheaper, that saving is gone. Check the difference in the income tax calculator before the due date, not after.

For people with business or professional income, the choice of the old regime is made through a separate form filed before the due date. Missing it has the same effect.

Losses cannot be carried forward

If you had a capital loss on shares or property, or a business loss, you can carry it forward to set off against future gains only if the return is filed by the due date. A belated return lets you carry forward a loss from house property, but not capital or business losses. For an active investor, this can cost far more than ₹5,000.

Refunds come later

If you are due a refund, filing late simply delays it. Processing starts only after you file and verify the return. Interest on a refund, where the department pays it, is also generally worked out with reference to when the return is filed, so a late return can mean less interest on your own money.

Less room to correct mistakes

A belated return can be revised if you spot an error, but only within the time limit allowed for revision. Filing in December leaves very little time to fix anything you missed, such as an FD interest entry in AIS or a forgotten capital gain. Filing on time gives you months of buffer.

Notices and interest risk

Not filing at all is worse than filing late. The department matches your PAN with AIS data from banks, employers and brokers. If income appears there and no return is filed, a notice can follow, and the eventual cost can include tax, interest and penalties well beyond the 234F fee.

How to pay the late fee and file a belated return

The fee has to be paid before you submit a belated return. The portal will not let you file with the fee unpaid. Here is the usual sequence.

1. Work out the fee and any tax due. Use this calculator for the fee and the interest calculator for 234A, 234B and 234C if tax is unpaid.
2. Pay through e-Pay Tax. Log in to the income tax e-filing portal, go to e-Pay Tax, and pay through Challan 280 for the correct assessment year. The fee is usually paid along with self-assessment tax and shown separately in the challan.
3. Keep the challan details. Note the BSR code, challan number and date of payment. These go into the "taxes paid" part of your return.
4. File the return under Section 139(4). In the ITR form, choose the belated return option. The fee appears in the tax computation; check that it matches what you paid.
5. E-verify within the time allowed. Verify using Aadhaar OTP, net banking or another accepted method. A return that is not verified is treated as not filed.

If the computation shows a fee or tax higher than what you paid, pay the difference before submitting. A mismatch can result in a demand later.

Common mistakes with the 234F calculation

• Using gross salary instead of total income. The ₹5 lakh test for the ₹1,000 fee is on total income after deductions. Someone with a gross salary of ₹5.6 lakh but total income of ₹4.85 lakh after the standard deduction pays ₹1,000, not ₹5,000.
• Thinking zero tax means no fee. In the new regime, income between ₹4 lakh and ₹12 lakh may have nil tax but still needs a return. Late filing means a fee.
• Taking the wrong due date. Due dates differ for audit cases and are sometimes extended by the department. Always check the date notified for that year.
• Assuming the fee rises every month. It does not. If you are already late, do not wait thinking the cost is going up daily. The fee will not change, but interest on unpaid tax will.
• Paying under the wrong year. The challan must be for the assessment year of the return you are filing. A payment under the wrong year will not reduce the fee shown in your return.
• Forgetting to e-verify. If you pay the fee and upload the return but do not verify it within the allowed time, the return is treated as not filed, and you may end up filing again later.
• Not checking AIS first. A rushed belated return that misses interest or a share sale shown in AIS can lead to a mismatch notice. Since you are already late, take the extra hour to match everything.
• Missing 31 December. After that, a belated return is no longer an option, and the updated return route is costlier.

If you have missed even the belated return deadline

Once the belated window has closed, you can still come forward through an updated return, often called ITR-U. It is meant for people who want to report income they missed or file a return they never filed.

An updated return comes with an additional tax, calculated as a percentage of the tax and interest due, and that percentage rises the longer you wait. It cannot be used to claim a refund or increase a loss, and there are other conditions. The late fee under 234F is also payable where it applies. Because the rules here are detailed and the cost is higher, have an expert review your case before filing an ITR-U.

Documents to keep ready before filing late

A late return still has to be correct. Collect these before you start, so you file once and file right.

• PAN and Aadhaar (linked), and login to the e-filing portal.
• Form 16 from each employer for that year.
• AIS and Form 26AS, to match TDS, interest, dividends and high-value transactions.
• Interest certificates for savings accounts and FDs.
• Capital gains statements from your broker or mutual fund registrar, if you sold anything.
• Deduction proofs, if you are still eligible for any in the new regime (for example, employer NPS contribution).
• Challan details of the late fee and any self-assessment tax you paid.
• Bank account details for the refund, pre-validated on the portal.

Not sure which ITR form to use? Our ITR form finder picks the right one in a few questions. Filing the wrong form can make the return defective, which adds another round of work.

When to take expert help

The calculator gives you the right fee for a normal case. Some situations need a closer look:

• your income is close to the exemption limit and you are unsure whether filing was compulsory;
• you have capital or business losses and want to understand what a late return costs you;
• the old regime would have saved you tax and you are deciding whether anything can still be done;
• you have missed returns for more than one year;
• you have received a notice for non-filing;
• you are past 31 December and are thinking about an updated return.

Our income tax filing service handles belated and updated returns, including the fee, interest and challan steps.
