Penalty Calculator
ITR Late Filing Penalty Calculator
Calculate exact penalties, interest, and late fees based on Indian compliance law
Missing the Income Tax Return deadline has three separate financial consequences: a flat late filing fee, interest on any unpaid tax, and the permanent loss of loss carry-forward rights.
The late filing fee under Section 234F is Rs. 10,000 for income above Rs. 5 lakh (Rs. 1,000 if income is below Rs. 5 lakh). For companies and LLPs, the fee is Rs. 10,000 regardless of income. This is a flat amount - not per day.
Interest under Section 234A accrues at 1% per month on outstanding tax from the original due date. Unlike the late fee, this continues to grow every month until the tax is actually paid. A company with Rs. 5 lakh of unpaid tax pays Rs. 5,000 per month in Section 234A interest.
The loss that cannot be quantified: if a company or LLP made a loss this year and files the ITR after October 31, it permanently loses the right to carry that loss forward against future profits. That tax benefit - potentially lakhs of rupees over the next 8 years - is gone forever. The calculator does not include this because it depends on your specific loss amount, but it is often the largest cost of filing late.
How to Use This Calculator
Due dates:
Individual ITR (non-audit): July 31
Company (all cases): October 31 - statutory audit is mandatory for all companies
LLP (no audit required): July 31
LLP (audit required - turnover above Rs. 1 crore): October 31
Business with tax audit: October 31
What the calculator shows:
Late filing fee (flat) + Section 234A interest (monthly on unpaid tax) + Section 234B interest if advance tax was short-paid.
What it does not show:
Loss carry-forward forfeiture. If you have business losses this year, calculate separately what you lose by filing late - often far more than the penalties shown.
