Section 206C: Interest on Delayed TCS Collection Explained
When it comes to tax compliance, timely collection and deposit of Tax Collected at Source (TCS) is crucial. Section 206C of the Income Tax Act, 1961 governs the provisions relating to TCS. A common issue faced by many businesses is the late collection of TCS, which triggers interest liability.
As per Section 206C of the Income Tax Act, any person responsible for collecting TCS who fails to collect it on time is liable to pay interest. This interest is not on the transaction value but on the TCS amount that was due to be collected.
Interest Rate on Late Collection
If TCS is not collected by the due date, the collector becomes liable to pay simple interest at the rate of 1% per month or part of a month. This applies from the date on which TCS was collectible to the date it is actually collected.
Period of Interest Calculation
The interest period begins from the date the TCS was due for collection and ends on the actual date of collection. Importantly, even a fraction of a month is considered a full month for interest computation.
✔️ Example:
If TCS for April is collected in June, interest is applicable for three full months – April, May, and June – regardless of the exact number of days.
Interest Computation Base
Interest is not levied on the transaction value but on the TCS amount that was required to be collected.
Rounding Off of Period
For the purpose of interest calculation:
A calendar month is considered.
Any part of a month is treated as a full month.
Illustrative Example
| Particulars | Amount / Details |
|---|---|
| TCS amount due | ₹1,00,000 |
| Month of liability | April |
| Actual collection | June |
| Interest rate | 1% per month |
| Total interest liability | ₹3,000 |
| Interest calculation | ₹1,00,000 × 1% × 3 months |
Important Notes on Time Period
A month is always taken as a calendar month, not 30 days or any custom duration.
Even a 1-day delay into the next calendar month invites a full month’s interest.
Practical Scenarios
| S. No. | Due Date for Collection | Actual Collection Date | Interest Period |
|---|---|---|---|
| 1 | 15-04-2025 | 15-04-2025 | 0 months |
| 2 | 15-04-2025 | 16-04-2025 | 1 month |
| 3 | 15-04-2025 | 01-05-2025 | 2 months |
| 4 | 15-04-2025 | 31-05-2025 | 2 months |
| 5 | 15-04-2025 | 30-06-2025 | 3 months |
As seen above, even a small delay crossing into the next calendar month leads to additional interest.
Tax Treatment of Interest
Disallowed Expense: Interest paid on late collection of TCS cannot be claimed as a deductible expense under the Income Tax Act.
Permanent Difference: Since this interest is disallowed, it results in a permanent difference in the computation of taxable income. Hence, no deferred tax is created on this liability.
Legal Provision (Bare Act Reference)
According to Section 206C(7) of the Income Tax Act:
“If the person responsible for collecting tax does not collect it, or after collecting fails to pay it as required, he shall be liable to pay simple interest at 1% per month or part thereof, from the date such tax was collectible to the date it is actually collected.”
In addition:
If the tax is collected but not deposited, interest is charged at 1.5% per month or part thereof from the date of collection to the date of deposit.
If the collector is not treated as an assessee in default under certain circumstances, interest applies only up to the date of filing of return by the buyer.
Final Thoughts
Timely collection and deposit of TCS is not just a matter of compliance—it can also save your business from interest costs that cannot be written off as expenses. A good accounting and compliance process is essential to ensure that such delays are avoided.
Key Takeaways
Interest at 1% per month applies to delayed collection of TCS.
Interest is calculated on the TCS amount, not the transaction value.
Even a 1-day delay leads to 1 full month of interest.
The interest cannot be claimed as an expense—it’s a permanent disallowance.
