Great question! Hereโs a clear explanation about how interest on late TDS deposit is calculated under the Income Tax Act:
---
### Interest on Late Deposit of TDS (Section 201(1A)):
* Interest is charged at **1% per month** or part of a month on the **amount of TDS not deposited**. * The **period of delay** is calculated from the **date of deduction** of TDS till the **date of actual deposit** with the government.
---
### How is the period of delay counted?
* The Act and CBDT circulars clarify that **any part of a month is counted as a full month**. * So even a delay of **1 day beyond the due date counts as one full month of interest**. * Interest is thus charged for **every calendar month or part thereof** during which the TDS amount remains unpaid.
---
### In your example:
| Event | Date | | ------------ | ----------- | | TDS Deducted | 22-Aug-2013 | | Due Date | 07-Sep-2013 | | Deposit Date | 08-Sep-2013 |
* The TDS should have been deposited **on or before 07-Sep-2013**. * Since deposit was made **on 08-Sep-2013** (one day late), this counts as a delay of **1 full month** (from 22-Aug to 22-Sep). * Additionally, since the payment date is beyond the due date, interest for the part of September is also counted. * Therefore, interest is calculated for **2 months**:
* 1 month from date of deduction (22-Aug to 22-Sep) * Plus 1 month for the delay past due date (07-Sep to 08-Sep), counted as a full month.
---
### Summary:
* Interest on late deposit of TDS is **calculated from date of deduction**. * **Any part of a month delay is counted as a full month**. * Hence, even a 1-day delay results in interest for 2 months in your case.
---
### Practical tip:
To avoid paying interest, always deposit TDS on or before the due date notified by the government (usually 7th or 30th of the next month depending on deductor type).
