Summary
Late filing can trigger a section 234F fee. The fee is ₹5,000 for income above ₹5 lakh. It drops to ₹1,000 when total income is up to ₹5 lakh. If tax is still unpaid, interest may also apply. 80c in new tax regime is not available. Taxpayers in Thane often need local filing help to avoid errors.
Introduction
Late filing can cost more than people expect. The Income Tax Department says a return filed after the due date can attract a fee under section 234F. If tax is unpaid, interest can also continue on that unpaid amount.
Many taxpayers miss the due date by mistake. Some delay because of documents. Others wait to confirm deductions like 80C. That is where confusion starts, especially for salaried people and small businesses in Thane.
This blog explains the late filing penalty in simple terms. You will also see how 80c in new tax regime is treated, what extra cost may apply, and when tax filing firms can help.
What is the penalty for late filing of income tax return?
The main late filing penalty is the fee under section 234F. The Income Tax Department says this fee applies when the return is furnished after the due date under section 139(1).
The fee is not the same as tax. It is a separate compliance cost. That means even if your tax is low, or nil in some cases, filing late can still create a fee liability.
For many taxpayers, this is the first surprise. They think delay only affects refunds. In reality, it can also reduce deductions and create avoidable filing stress later.
How much fee applies under section 234F?
The fee under section 234F is ₹5,000 if your return is late and total income is above ₹5 lakh. If total income does not exceed ₹5 lakh, the fee is ₹1,000.
The department also states that no fee is payable where the person is not liable to furnish a return at all. That is a narrow situation, not a general rule for most salaried or business taxpayers.
A simple example helps. A resident salaried employee with taxable income above ₹5 lakh files after the due date. The return may still be accepted as a belated return, but the fee can still apply.
Does unpaid tax create more cost after the due date?
Yes. The department says delay in filing can attract interest on unpaid tax from the due date to the actual filing date. It is generally charged at 1% per month or part thereof on the unpaid amount.
That means the cost can rise in two layers. First comes the late filing fee. Then comes interest if self-assessment tax is still pending.
This matters for people in Thane who wait until the last week. Even a short delay can become expensive if tax was not already paid. A tax filing firm can help close that gap before filing.
Can you still file a late return after the due date?
Yes. A belated return is allowed, subject to the law and time limits. The Income Tax Department says it can be filed three months before the end of the relevant assessment year, or before assessment is completed, whichever is earlier.
For AY 2026-27, the department gives 31 December 2026 as the example last date for a belated return, unless the assessment is completed earlier.
That still does not make late filing harmless. The fee can still apply, and your refund may get delayed too. So it is better to file on time whenever possible.
Is 80C available in the new tax regime?
No. Under the new tax regime, section 80C cannot be claimed. The Income Tax Department’s current instructions and return guidance state that these deductions cannot be claimed if the new tax regime under section 115BAC is opted.
That is important for taxpayers who delay filing because they are still collecting 80C proofs. If you have chosen the new regime, 80C should not be your filing reason. The deduction does not reduce tax there.
What still matters is choosing the right regime early. The new regime may still allow some salary-linked benefits, such as the standard deduction shown by the department’s current employee benefits guidance.
How can taxpayers in Thane avoid late filing and missed deductions?
The easiest way is to prepare early. Keep salary slips, bank statements, Form 16, and investment proofs together before the due date. That avoids last-minute checks and wrong assumptions.
People in Thane often juggle salary, freelance work, or small business income. In such cases, tax filing firms help match the return type, regime choice, and proof records. That reduces filing mistakes.
A local tax filing firm can also help you check whether old-regime deductions are worth claiming. If you are under the new regime, it can stop you from wasting time on 80C paperwork that will not help.
Why do tax filing firms help more than last-minute filing?
Tax filing firms help because late filing problems are usually small at first. A missing form, wrong regime choice, or unpaid tax amount can all create a bigger issue later.
For taxpayers and businesses in Thane, local support is practical. It makes follow-up easier and reduces the chance of filing the wrong return or missing the final date.
This is especially useful for people who rely on corporate tax filing services or handle mixed income. One review before filing can save both money and stress.
