How this tool counts months. Interest under section 201(1A) (and section 394/206C(7) for TCS) is charged for "every month or part of a month." In practice the Department treats the month of deduction and the month of payment as two separate months, so a delay that works out to one month is demanded as two months. This tool follows that practice by default — a 1-month delay is charged for 2 months, while a 3-month delay stays at 3 months, and so on. You can switch it off to see the literal day-count computation.

Interest on late deduction / deposit

Section 201(1A): 1% per month for late deduction, 1.5% per month for late deposit after deduction. TCS under section 394: 1% per month.
