Income tax: Rs 100 for every month or part-month the return is late, plus 15% p.a. interest on the outstanding tax, pro-rated by days late. A further fee of 0.1% p.a. of assessable income can also apply under s.117; it is not computed here since assessable income isn't entered. An indicative estimate only, as of current law. Confirm your exact liability with the Inland Revenue Department before relying on this figure.
Two regimes, one shared interest rate
Income tax and VAT calculate their late fee differently, but both charge 15% p.a. interest on the tax that stays unpaid.
Days late, from two dates
Days late is the plain calendar gap between the due date and the actual (or planned) filing/payment date, floored at zero.
Late fee, by regime
Income tax: Rs 100 per month or part-month late. VAT: 0.05% of the tax due per day late, or Rs 1,000 per return, whichever is greater.
Interest, always pro-rated
15% p.a. on the outstanding tax, pro-rated by days late (tax due × 15% × days ÷ 365), applies in both regimes, even if the return itself was filed on time.
Late filing, fees and interest, answered
What is the difference between the late fee and interest?+
The late fee is a fixed penalty for filing (or not filing) the return by the due date, Rs 100 per month or part-month for income tax, or 0.05% of the tax due per day (minimum Rs 1,000) for VAT. Interest, separately, is charged at 15% per annum on the outstanding tax itself, for every day it remains unpaid. A return can attract both, one, or neither, depending on whether it was filed late and whether the tax was paid late.
I filed on time but paid the tax late, do I still owe anything?+
Yes. The late fee is tied to the filing deadline, so filing on time avoids it. But interest at 15% p.a. is charged on any tax that remains unpaid past its due date, regardless of when the return itself was filed. Set the actual date to your payment date, not just your filing date, to see the interest that applies.
Why does the VAT fee floor at Rs 1,000?+
VAT's late fee is 0.05% of the tax due for each day late, but the law sets a Rs 1,000 minimum per return. For small tax amounts or short delays, the daily-rate calculation often works out below Rs 1,000, so the minimum takes over. For example, Rs 50,000 due and 30 days late gives a daily-rate fee of only Rs 750, so the Rs 1,000 floor applies instead.
Does the income tax fee include the income-based additional fee?+
No. Alongside the Rs 100 per month or part-month fee, the Income Tax Act allows a further fee of 0.1% per annum of assessable income, pro-rated by months late, to also apply. This calculator does not collect your assessable income, so it computes only the flat Rs 100/month component; your total statutory fee may be higher if that additional fee is assessed.
How are 'days late' and 'months late' counted?+
Days late is the plain calendar difference between your due date and your actual (or planned) filing/payment date, floored at zero, a return filed on or before the due date shows zero fee and interest. For income tax, any part of a month counts as a full month for the Rs 100 fee, so 31 days late is charged as 2 months, not 1.
