How to Use This Calculator

Late Deposit Interest tab

Enter the TDS amount deducted, the date TDS was deducted, and the date TDS was actually deposited with the government. The calculator computes the number of months of delay (part of a month = full month) and applies 1.5% per month interest under Section 201(1A). It also shows the statutory due date for deposit (7th of the following month, or 30 April for March deductions).

Late Deduction Interest tab

Enter the TDS amount, the date the payment was made (when TDS should have been deducted), and the date TDS was actually deducted. Interest at 1% per month applies for the delay period. The calculator also warns about additional late deposit interest if TDS is not deposited by the due date after deduction.

Late Filing Penalty tab

Enter the TDS return due date (Q1: 31 Jul, Q2: 31 Oct, Q3: 31 Jan, Q4: 31 May), the actual filing date, and the total TDS amount in the return. The calculator computes the Section 234E late fee (&rupee;200/day, capped at TDS amount) and checks whether Section 271H penalty (&rupee;10,000–&rupee;1,00,000) applies based on the Budget 2024 amendment (1-month safe harbor).

The Formula

Interest and penalties for TDS non-compliance are governed by Sections 201(1A), 234E, and 271H of the Income Tax Act:

Late Deposit Interest (Section 201(1A)):
Interest = TDS Amount × 1.5% × Number of Months
Period: Date of deduction → Date of actual deposit
Part of a month = full month

Late Deduction Interest (Section 201(1A)):
Interest = TDS Amount × 1% × Number of Months
Period: Date payment made (when TDS was due) → Date TDS actually deducted
Part of a month = full month

Late Filing Fee (Section 234E):
Fee = &rupee;200 × Number of Days of Delay
Maximum fee = Total TDS amount in the return

Late Filing Penalty (Section 271H):
Penalty: &rupee;10,000 to &rupee;1,00,000 (at AO's discretion)
No penalty if: TDS deposited + late fee/interest paid + return filed within 1 month of due date
(Budget 2024 amendment, effective 1 April 2025 — previously 1 year)

All interest rates are per month, not per annum. The “part of month = full month” rule means even a 1-day delay into the next calendar month counts as a full additional month of interest. This makes timely compliance critical.

Example

Priya — Bangalore business owner who missed TDS deposit deadlines

Priya runs a consulting firm. She deducted TDS of &rupee;50,000 on a contractor payment on 15 January 2026 but only deposited it on 15 March 2026. She also filed the Q3 TDS return (due 31 January 2026) on 15 April 2026.

Step 1: Late Deposit Interest

TDS deducted&rupee;50,000
Date deducted15 Jan 2026
Due date for deposit7 Feb 2026
Actual deposit date15 Mar 2026
Months of delay2 months (Jan → Mar)
Interest (1.5% × 2)&rupee;1,500

Step 2: Late Filing Penalty

Q3 return due date31 Jan 2026
Actual filing date15 Apr 2026
Days of delay74 days
Section 234E fee&rupee;200 × 74 = &rupee;14,800
Filed within 1 month?No (74 days > 1 month)
Section 271H penalty&rupee;10,000 to &rupee;1,00,000

Total liability

Late deposit interest&rupee;1,500
Section 234E late fee&rupee;14,800
Section 271H penalty (min)&rupee;10,000
Total (minimum)&rupee;26,300

Priya's total liability of at least &rupee;26,300 on a &rupee;50,000 TDS amount shows why timely compliance matters. Had she deposited by 7 February and filed by 31 January, her liability would have been &rupee;0.

FAQ

Under Section 201(1A) of the Income Tax Act, interest for late deposit of TDS is 1.5% per month (or part of a month) from the date of deduction to the date of actual deposit. This is not an annualized rate — it is 1.5% for each month of delay. For example, 3 months late on &rupee;1,00,000 TDS means &rupee;1,00,000 × 1.5% × 3 = &rupee;4,500 in interest. The interest must be deposited before filing the TDS return.
Both are under Section 201(1A) but apply to different defaults:

Late deduction (1% per month): When TDS was not deducted at the time of payment/credit. Interest runs from the date when TDS should have been deducted to the date it was actually deducted.

Late deposit (1.5% per month): When TDS was deducted but not deposited with the government on time. Interest runs from the date of deduction to the date of actual deposit.

If you both deducted late AND deposited late, both interests apply — but they cover different periods and don't overlap.
When calculating TDS interest, any partial month is treated as a complete month. For example, if TDS was deducted on 28 January and deposited on 2 February, even though only 5 days passed, it spans two calendar months (January and February). So the interest would be calculated for 2 months, not 1. This makes even a small delay across month boundaries quite costly. Always try to deposit TDS well before the month-end to avoid accidentally triggering an extra month of interest.
The Finance (No. 2) Act 2024 amended Section 271H, effective from 1 April 2025. Previously, no penalty was imposed if the TDS/TCS return was filed within 1 year of the due date (provided TDS was deposited and fees/interest were paid). This safe-harbor period has been reduced from 1 year to 1 month. Now, to avoid the penalty of &rupee;10,000 to &rupee;1,00,000, you must file the return within 1 month of the due date. This change significantly tightens compliance requirements for FY 2025-26 onwards.
No. Interest paid under Section 201(1A) for late deduction or late deposit of TDS cannot be claimed as a business expenditure under Section 40(a)(ii) of the Income Tax Act. Similarly, the late filing fee under Section 234E and the penalty under Section 271H are not deductible expenses. These are penal in nature and must be borne by the deductor from after-tax income.
