Heavy losses due to missing the deadline

Even if you miss the deadline of 15 September, you can still file a ‘belated return’ till 31 December 2025. But, for this, you will have to bear some losses. If your income is more than ₹ 5 lakh, then a fine of ₹ 5,000 will be imposed. Those whose income is less than ₹ 5 lakh will have to pay a fine of ₹ 1,000. You will not be able to carry forward the capital loss incurred by selling shares, mutual funds, or property. You will not be able to claim many exemptions available under the old tax regime. Under section 234A, interest will also have to be paid at the rate of 1% every month on the outstanding tax.

If you miss the deadline for delayed returns, the Income Tax Act gives the option of an ‘updated return’. It was implemented in 2022, under which you can file ITR within 48 months. Its purpose is to give you a chance to declare your missed income and pay tax on it.

You cannot claim any additional loss or refund, nor can you reduce your tax liability. You have to pay additional tax on filing an updated return. If you file within 12 months of the assessment year, you will have to pay an additional tax of 25%, 50% in 24 months, 60% in 36 months, and 70% in 48 months. You can avoid all these difficulties by filing ITR on time.
