TDS Interest Calculator: Calculate Interest on TDS Deductions
Module A: Introduction & Importance of TDS Interest Calculation
Tax Deducted at Source (TDS) is a crucial mechanism in the Indian tax system where tax is deducted at the source of income. When TDS is deducted but not deposited with the government within the prescribed time limits, interest becomes payable under Section 201(1A) of the Income Tax Act, 1961.
Understanding how interest on TDS is calculated is essential for:
- Businesses to avoid unnecessary interest payments
- Tax professionals to advise clients accurately
- Individuals to verify their tax deductions
- Compliance with Income Tax Department requirements
The interest calculation depends on:
- The amount of TDS deducted
- The date of deduction vs. date of deposit
- The applicable interest rate (currently 1% or 1.5% per month)
- Whether the delay is in deduction or payment

Module C: Formula & Methodology Behind TDS Interest Calculation
The interest on delayed TDS payment is calculated using the following precise methodology:
1. Basic Calculation Formula
The fundamental formula is:
Interest = (TDS Amount × Interest Rate × Number of Months) / 100
2. Key Components Explained
| Component | Definition | Calculation Rules |
|---|---|---|
| TDS Amount | The actual tax deducted at source | Use exact amount as per Form 26AS |
| Interest Rate | Percentage charged per month | 1% for standard delays, 1.5% for serious non-compliance |
| Number of Months | Duration of delay |
|
3. Special Cases & Exceptions
Several special scenarios affect the calculation:
-
Partial Months: Even 1 day of delay counts as 1 full month
- Example: 15-day delay = 1 month for calculation
- Example: 45-day delay = 2 months for calculation
-
Rate Changes: Different rates may apply for different periods
- 1% for delays in deposit after deduction
- 1.5% for failure to deduct TDS itself
-
Government Holidays: Deposit deadlines extended when due date falls on holiday
- Check Income Tax Department for official holidays
4. Legal Provisions
The calculation is governed by:
- Section 201(1A) of Income Tax Act, 1961 – Interest for delay in deposit
- Section 201(1A)(i) – 1% per month for delay in deposit after deduction
- Section 201(1A)(ii) – 1.5% per month for failure to deduct

Module G: Interactive FAQ on TDS Interest Calculation
What is the exact legal provision for TDS interest calculation?
The legal provision is Section 201(1A) of the Income Tax Act, 1961. It states:
- 1% per month from deduction date to deposit date (for delay in deposit after proper deduction)
- 1.5% per month from due date to actual deduction date (for failure to deduct TDS)
The interest is calculated for each month or part of a month of delay. The Income Tax Department provides official circulars with detailed explanations.
How is the number of months calculated for partial delays?
The Income Tax Department follows these rules for partial months:
- Any fraction of a month is rounded up to a full month
- Example: 15 days delay = 1 month
- Example: 45 days delay = 2 months (1 full + 15 days rounded up)
- The counting starts from the day after the due date
This is clearly mentioned in CBDT Circular No. 1/2012 dated 09-04-2012.
What happens if TDS is deducted but not deposited at all?
If TDS is deducted but never deposited, the following consequences apply:
- Interest at 1% per month from deduction date until payment
- Potential penalty under Section 271C (100% to 300% of TDS amount)
- Disallowance of expense under Section 40(a)(ia) (30% of amount)
- Possible prosecution under Section 276B (3 months to 7 years imprisonment)
The interest continues to accrue until the amount is actually deposited with the government.
Can I get a waiver or reduction in TDS interest?
In rare cases, interest may be reduced or waived:
-
Reasonable Cause: If you can prove the delay was due to reasons beyond your control
- Natural calamities
- Bank strikes
- Serious illness of authorized person
-
Voluntary Disclosure: If you disclose before detection by department
- May get partial relief
- Must show genuine intent to comply
-
Small Amounts: For very small delays and amounts
- Generally below ₹1,000 interest
- Discretion of Assessing Officer
You would need to file an application to the Assessing Officer with proper justification and evidence.
How does TDS interest affect my income tax return?
The TDS interest has several impacts on your tax return:
-
Additional Liability: The interest becomes payable along with your tax
- Shown as “Interest Payable” in tax computation
- Must be paid before filing return
-
Disallowance of Expenses: Under Section 40(a)(ia)
- 30% of the amount on which TDS was deducted but not deposited
- Can be reversed in year of payment
-
Cash Flow Impact: Unexpected interest can affect working capital
- Plan for this additional expense
- May affect your tax payment schedule
-
Audit Implications: May trigger scrutiny
- Large interest amounts can lead to questions
- Be prepared with documentation
The interest is not allowable as a business expense under Section 37.
What are the due dates for TDS deposit to avoid interest?
The due dates vary based on the type of payment:
| Type of Payment | Due Date for Deposit | Relevant Section |
|---|---|---|
| Salary (Government) | Same day (no separate due date) | Rule 30 |
| Salary (Non-Government) | 7th of the following month | Rule 30 |
| Non-Salary (March) | 30th April | Rule 30 |
| Non-Salary (Other months) | 7th of the following month | Rule 30 |
| TDS on Property (Section 194IA) | 30th day from end of month of deduction | Rule 30 |
Note: When the due date falls on a Sunday or holiday, the next working day becomes the due date.
How is TDS interest different from TDS penalty?
TDS interest and penalty are distinct concepts:
| Aspect | TDS Interest (Section 201(1A)) | TDS Penalty (Section 271C) |
|---|---|---|
| Nature | Compensatory (for delayed payment) | Punitive (for default) |
| Rate | 1% or 1.5% per month | 100% to 300% of TDS amount |
| Calculation | Based on delay period | Flat percentage of TDS amount |
| Waiver Possible | Rare, only with strong justification | Possible with reasonable cause |
| Tax Treatment | Not deductible | Not deductible |
| Imposed By | Automatic by system | By Assessing Officer |
In most cases, both interest and penalty may be levied for serious defaults.
