What is TDS Interest?
TDS interest is the penalty charged by the Income Tax Department when a deductor fails to deduct or deposit TDS on time. Under Section 201(1A) of the Income Tax Act, 1961, interest is levied on two types of defaults: late deduction and late deposit of TDS.
Every person responsible for deducting tax at source must do so at the prescribed time and deposit the deducted amount with the government within the specified due dates. Failure to comply results in interest charges calculated on a monthly basis. This is separate from the TDS amount itself, which must still be paid in full.
- Interest at 1% per month applies when TDS is not deducted at the time of payment or credit to the payee
- Interest at 1.5% per month applies when TDS is deducted but not deposited with the government by the due date
- Part of a month is treated as a full month for interest calculation purposes
- Section 234E imposes an additional late filing fee of Rs 200 per day for delayed TDS return filing

How is TDS Interest Calculated?
TDS interest is calculated separately for late deduction and late deposit. The formulas are straightforward, but the month-counting rule makes the calculation specific to TDS provisions.
Interest = TDS Amount x Rate x Number of Months
Late Deduction (Section 201(1A)(i)): Interest at 1% per month from the date on which TDS was deductible to the date of actual deduction
Late Deposit (Section 201(1A)(ii)): Interest at 1.5% per month from the date of deduction to the date of actual deposit
Month Counting Rule: Any part of a month is considered a full month. The count includes the month in which the default started and the month in which it ended
For businesses dealing with multiple vendors and contractors, tracking TDS due dates becomes complex. A TDS on Rent Calculator can help determine the correct TDS amount for rental payments, while this tool calculates the penalty if deadlines are missed.
TDS Interest Calculation with Example
Let us walk through a practical example to understand how TDS interest is computed for both late deduction and late deposit scenarios.
Scenario: A company was required to deduct TDS of Rs 1,00,000 on April 10, 2025, but actually deducted it on June 25, 2025. The TDS was deposited on July 15, 2025 (due date was July 7, 2025).
Interest on Late Deduction:
From April to June = 3 months
Rs 1,00,000 x 1% x 3 = Rs 3,000
Interest on Late Deposit:
From June to July = 2 months (part of June + part of July)
Rs 1,00,000 x 1.5% x 2 = Rs 3,000
Total Interest Payable: Rs 3,000 + Rs 3,000 = Rs 6,000
In this example, the company faces a combined penalty of Rs 6,000 on a TDS amount of Rs 1,00,000, representing a 6% cost of non-compliance over just three months. This demonstrates why timely TDS deduction and deposit is critical for businesses.
TDS Penalty Rates and Sections
The Income Tax Act prescribes different penalty rates for different types of TDS defaults. Here is a comprehensive comparison of all TDS-related penalties and their governing sections:
| Default Type | Section | Rate / Fee | Period |
|---|
| Late Deduction of TDS | 201(1A)(i) | 1% per month | Due date to actual deduction date |
| Late Deposit of TDS | 201(1A)(ii) | 1.5% per month | Deduction date to actual deposit date |
| Late Filing of TDS Return | 234E | Rs 200 per day | Due date to actual filing date (capped at TDS amount) |
| Failure to Deduct TDS | 271C | Equal to TDS amount | Penalty imposed by Assessing Officer |
| Failure to File TDS Return | 271H | Rs 10,000 to Rs 1,00,000 | Penalty imposed by Assessing Officer |
The interest under Section 201(1A) and fee under Section 234E are automatic and must be paid along with the TDS amount. Penalties under Sections 271C and 271H are imposed by the Assessing Officer after a hearing. Similar to how GST late fees accrue on delayed returns, TDS penalties compound quickly with longer delays.
How to Avoid TDS Penalties
Preventing TDS penalties requires a systematic approach to tax compliance. Here are the best practices that businesses should follow to avoid interest charges and late fees:
- Maintain a TDS calendar: Set reminders for the 7th of every month (TDS deposit due date) and quarterly return filing deadlines. Missing even one date triggers interest
- Deduct TDS at the time of payment or credit: TDS must be deducted at the earlier of payment or credit to the payee's account. Do not wait for the actual payment
- Use electronic payment (Challan 281): Pay TDS online through the Income Tax portal or authorized banks. Keep challan receipts for records
- File TDS returns on time: Quarterly returns (Form 24Q for salary, 26Q for non-salary) must be filed within the prescribed deadlines to avoid Section 234E fees
- Verify TAN and PAN details: Incorrect TAN or PAN on challans and returns causes mismatches and processing delays
- Automate TDS compliance: Use accounting software that tracks TDS obligations, calculates amounts, and generates challans and returns automatically
Businesses in the food and hospitality industry should pay special attention to TDS on rent (Section 194I), TDS on contractor payments (Section 194C), and TDS on professional fees (Section 194J). For GST compliance alongside TDS, refer to this guide on GST filing for restaurants.

TDS Due Dates for FY 2025-26
TDS deducted during each quarter must be deposited and returns filed by specific deadlines. Missing these dates triggers interest under Section 201(1A) and late filing fees under Section 234E. Here are the key due dates for FY 2025-26:
| Quarter | Period | TDS Deposit Due Date | TDS Return Due Date |
|---|
| Q1 | April - June | 7th of following month | July 31 |
| Q2 | July - September | 7th of following month | October 31 |
| Q3 | October - December | 7th of following month | January 31 |
| Q4 | January - March | April 30 (for March), 7th for Jan/Feb | May 31 |
Note that TDS deducted in any month (except March) must be deposited by the 7th of the following month. For March, the due date for deposit is April 30. Government deductors can deposit TDS on the same day without using a challan. These deadlines apply to all types of TDS including salary (Form 24Q), non-salary (Form 26Q), and payments to non-residents (Form 27Q).
