TDS Late Payment Interest Calculator
Calculate the exact interest payable on delayed TDS payments as per Section 201(1A) of the Income Tax Act, 1961. Avoid penalties by computing the 1% per month interest on late deductions.
Introduction & Importance of TDS Late Payment Interest Calculator
Tax Deducted at Source (TDS) is a critical mechanism under the Income Tax Act, 1961 that ensures tax collection at the source of income. When TDS is deducted but not deposited with the government within the prescribed due dates, Section 201(1A) mandates payment of interest at 1% per month or part thereof on the delayed amount.
This calculator helps taxpayers, employers, and businesses:
- Compute exact interest liability for late TDS payments
- Avoid unnecessary penalties and legal notices
- Plan cash flows by estimating future liabilities
- Maintain compliance with Department of Revenue guidelines
How to Use This Calculator
Follow these steps to accurately calculate your TDS late payment interest:
- Enter TDS Amount: Input the exact TDS amount that was deducted (in ₹)
- Select Dates:
- Deduction Date: When TDS was actually deducted from payment
- Payment Date: When TDS was finally deposited with government
- Choose TDS Type: Select the appropriate section under which TDS was deducted
- Calculate: Click the button to get instant results including:
- Delay period in days
- Applicable interest rate (always 1% per month)
- Total interest payable
- Final amount to be paid (TDS + interest)
Pro Tip: The calculator automatically rounds up partial months. Even 1 day delay counts as 1 full month for interest calculation as per Income Tax Act provisions.
Formula & Methodology
The interest calculation follows this precise methodology:
1. Determine the Delay Period
Delay (in months) = Ceiling[(Payment Date – Due Date)/30]
Where:
- Due Date = 7th of next month (for most TDS types)
- Payment Date = Actual date of deposit
- Ceiling function rounds up to nearest whole number
2. Calculate Monthly Interest
Interest = TDS Amount × (1% × Number of Months Delayed)
Key points:
- Interest is compounded monthly but calculated simply as 1% of principal for each month
- No interest is charged if payment is made on or before due date
- Interest is calculated for each day of delay, but charged per completed/partial month
3. Total Payable Amount
Total = TDS Amount + Interest
Real-World Examples
Case Study 1: Salary TDS Delay
Scenario: Company deducted ₹50,000 as TDS from employee salary on 30th April but deposited it on 15th June instead of by 7th May.
Calculation:
- Delay Period: 30 April to 15 June = 46 days → 2 months (rounded up)
- Interest: ₹50,000 × 1% × 2 = ₹1,000
- Total Payable: ₹50,000 + ₹1,000 = ₹51,000
Case Study 2: Professional Fees TDS
Scenario: Freelancer received ₹1,20,000 payment on 10th March with 10% TDS (₹12,000). The deductor paid TDS on 5th May instead of by 7th April.
Calculation:
- Delay Period: 7 April to 5 May = 28 days → 1 month
- Interest: ₹12,000 × 1% × 1 = ₹120
- Total Payable: ₹12,000 + ₹120 = ₹12,120
Case Study 3: Multiple Months Delay
Scenario: Rent TDS of ₹25,000 deducted on 30th November but paid on 20th March of next year.
Calculation:
- Delay Period: 7 December to 20 March = 104 days → 4 months
- Interest: ₹25,000 × 1% × 4 = ₹1,000
- Total Payable: ₹25,000 + ₹1,000 = ₹26,000

What happens if I don’t pay the TDS late payment interest?
Non-payment of TDS late payment interest can lead to:
- Issuance of Section 201 notice from Income Tax Department
- Disallowance of expenditure under Section 40(a)(ia) (30% of payment becomes non-deductible)
- Prosecution under Section 276B (rigorous imprisonment up to 7 years)
- Additional penalty under Section 271C (equal to TDS amount)
The interest becomes a statutory liability that cannot be waived even if you later pay the principal TDS amount.
Is the 1% interest calculated on monthly reducing balance?
No, the 1% interest under Section 201(1A) is calculated on the entire outstanding TDS amount for each month of delay. It’s not calculated on reducing balance like some loan interests.
Example: If you delay ₹1,00,000 TDS payment by 3 months, the interest will be:
₹1,00,000 × 1% × 3 = ₹3,000
Not:
Month 1: ₹1,00,000 × 1% = ₹1,000
Month 2: ₹99,000 × 1% = ₹990
Month 3: ₹98,010 × 1% = ₹980.10
Total: ₹2,970.10
The Income Tax Department always uses the first (simpler) method.
Can I claim this interest as business expense in my income tax return?
No, the interest paid under Section 201(1A) is not allowable as business expenditure under Section 37 of the Income Tax Act. This was confirmed by:
- Supreme Court in Karnataka Power Corporation vs CIT [2000] 247 ITR 268
- Delhi High Court in CIT vs Anjum M.H. Ghaswala [2001] 252 ITR 1
The interest represents a penal consequence for statutory non-compliance, not a business cost.
What is the due date for TDS payment for different quarters?
| Quarter | Period | Due Date for TDS Payment | Due Date for TDS Return |
|---|---|---|---|
| Q1 | April – June | 7th July | 31st July |
| Q2 | July – September | 7th October | 31st October |
| Q3 | October – December | 7th January | 31st January |
| Q4 | January – March | 30th April | 31st May |
Note: For March month TDS (Q4), the due date is 30th April instead of 7th April to allow time for year-end processing.
How is the interest calculated if the delay spans multiple financial years?
The interest calculation remains the same regardless of financial year boundaries. The key points are:
- Delay is calculated from the original due date to actual payment date
- Financial year change doesn’t reset the interest calculation
- Interest continues to accrue at 1% per month until full payment
Example: TDS deducted on 15th March 2023 (due by 30th April 2023) but paid on 15th June 2024:
- Delay Period: 30 April 2023 to 15 June 2024 = 412 days
- Months of Delay: 412/30 = 13.73 → 14 months (rounded up)
- Interest: TDS Amount × 1% × 14
The assessment year for this interest would be AY 2024-25 (when payment was made).
