Missing the income tax return (ITR) deadline or failing to comply with other provisions of the Income Tax Act can prove expensive. Depending on the nature of the default, taxpayers may have to pay late filing fees, interest or penalties. In some cases, the penalty can be be as high as 200% of the tax payable on the income that was incorrectly reported, according to the Income Tax Department.

Besides filing the ITR on time, taxpayers are also required to accurately report all sources of income, pay taxes within the prescribed timelines and maintain books or records wherever applicable. Different types of non-compliance attract different consequences under the Income Tax Act.

Penalty for late ITR filing and under-reporting of income

One of the most common defaults is filing the ITR after the due date. Under Section 234F of the Income Tax Act, a taxpayer filing the return after the prescribed deadline may have to pay a late filing fee of up to 5,000. However, where the total income does not exceed 5 lakh, the fee is restricted to 1,000, according to the Income Tax Department.

Another important provision is Section 270A, which deals with under-reporting and misreporting of income. If a taxpayer under-reports income, the penalty is equal to 50% of the tax payable on the under-reported income. However, where the under-reporting amounts to misreporting, such as suppression of facts, recording false entries or making incorrect claims, the penalty increases to 200% of the tax payable on that income.

Apart from late filing and under-reporting of income, the Income Tax Act prescribes penalties and fees for several other defaults.
