The standard deadline for filing individual income tax returns in India is July 31st of the Assessment Year. If you miss this date, you can still file a "Belated Return" up to December 31st. However, filing late comes with financial consequences. Under Section 234F, the income tax portal will block your submission until a late fee is paid. Let's look at the rules.

The Section 234F Penalty Structure

The penalty amount depends entirely on your total gross income:

• Income Below Basic Exemption: If your total income is below the basic tax threshold, no late fee is charged (though filing may still be required in specific circumstances).
• Income up to ₹5 Lakh: If your total gross income exceeds the basic exemption limit but is below ₹5 Lakh, the late fee is legally capped at ₹1,000.
• Income above ₹5 Lakh: If your total gross income exceeds ₹5 Lakh, filing a belated return attracts a flat penalty of ₹5,000.

Additional Penalty: Section 234A Interest

In addition to the late filing fee, if you have unpaid tax liabilities, you will be charged interest under Section 234A. This interest is calculated at 1% per month (or part of a month) from the deadline (July 31st) until the date you actually file the return.
