How is the 234F Late Fee Calculated?
Section 234F — Late Filing Fee Slabs
A flat fee is charged the moment you file your ITR after the due date. The amount depends only on your total income — not on how late you are.
| Total Income | Late Fee (234F) |
|---|---|
| Below basic exemption limit | ₹0 |
| Up to ₹5,00,000 | ₹1,000 |
| Above ₹5,00,000 | ₹5,000 |
Section 234A — Interest on Unpaid Tax
Interest under Section 234A runs at 1% per month (or part of a month) on any self-assessment tax still unpaid, from the day after the due date until you actually file and pay.
Deadlines & What Happens If You Miss Them
1. What is Section 234F?
Section 234F imposes a mandatory late filing fee when you submit your Income Tax Return after the due date under Section 139(1). It is a fixed fee — ₹1,000 for small taxpayers (total income up to ₹5 lakh) and ₹5,000 for everyone else.
2. Who is exempt from the 234F fee?
If your gross total income is below the basic exemption limit (₹4,00,000 under the new regime for FY 2025-26, or ₹2,50,000 / ₹3,00,000 / ₹5,00,000 under the old regime by age), you are generally not required to file — so no 234F fee applies. Note: you may still be required to file in special cases (foreign assets, high-value deposits, etc.).
3. Section 234A interest — the hidden cost
Beyond the flat 234F fee, if you have unpaid self-assessment tax, Section 234A adds simple interest at 1% for every month (or part month) of delay. Interest under Sections 234B and 234C may also apply for advance-tax shortfalls.
4. Other consequences of late filing
- Loss of carry-forward: Business and capital losses cannot be carried forward if you file late.
- Delayed refunds: Any refund due to you is processed later and may earn less interest.
- Reduced regime flexibility: Certain elections must be made by the original due date.
