Section 234D: Interest on Excess Income Tax Refund
Section 234D of the Income-tax Act, 1961 provides for interest when a refund granted while processing a return is subsequently found to be wholly or partly excessive on regular assessment. Its corresponding provision in the Income-tax Act, 2025 is Section 426.
What does Section 234D mean?
When the Income Tax Department processes a return under Section 143(1), it may issue a refund based on the return and permitted adjustments. A later scrutiny or other qualifying regular assessment may determine that the taxpayer was entitled to a smaller refund, or to no refund. Section 234D charges interest for the period during which the taxpayer held the excess amount.
This is distinct from Section 244A, which governs interest payable by the Government to taxpayers on eligible refunds. Section 234D concerns interest payable by the taxpayer when the earlier refund proves excessive.
When is interest payable?
- A refund was granted under Section 143(1) of the 1961 Act.
- On regular assessment, either no refund is due, or the refund legally due is smaller than the amount already granted.
- Interest is calculated on the entire earlier refund if nothing was due, or only on the excess portion if a smaller refund remains due.
Interest rate and calculation period
| Component | Rule under Section 234D |
|---|---|
| Rate | Simple interest at 0.5% per month or part of a month |
| Amount | Refund granted less refund determined to be due on regular assessment (not below zero) |
| Starting date | Date of grant of refund under Section 143(1) |
| Ending date | Date of regular assessment |
| Later relief | Interest is reduced where a qualifying subsequent order establishes that more of the original refund was correctly allowed |
Basic formula: Excess refund × 0.5% × number of chargeable months (including any part of a month). Statutory rounding rules and the exact dates must be checked when preparing a tax computation.
Illustrative example
Suppose a taxpayer receives a refund of Rs. 1,00,000 under Section 143(1). A later regular assessment determines that only Rs. 40,000 was refundable. The excess is Rs. 60,000. Assuming the applicable interest period comprises six chargeable months, interest is Rs. 60,000 × 0.005 × 6 = Rs. 1,800. The example is illustrative and excludes any separate tax demand or other statutory adjustments.
Section 234D: Subsections and explanations
Subsection (1): Liability on excess refund
If a refund was granted under Section 143(1) but no refund is due on regular assessment, or the earlier refund exceeds the amount ultimately due, the taxpayer must pay simple interest at 0.5% for each month or part of a month from the refund date to regular assessment on the whole or excess amount, as applicable.
Subsection (2): Reduction after later orders
Where a rectification, appeal, revision or other order specified in the provision establishes that all or part of the refund was correctly granted, the Section 234D interest must be reduced accordingly. Taxpayers should check that the revised computation gives effect to the order.
Explanation 1: First assessment in reassessment proceedings
Where the first assessment for an assessment year is made under the qualifying reassessment provisions, that assessment is treated as a regular assessment for Section 234D. The statutory wording refers to Sections 147 and 153A, as applicable to the relevant proceedings.
Explanation 2: Earlier assessment years
The 1961 Act clarifies that Section 234D may also apply to assessment years beginning before 1 June 2003 where the relevant proceedings were completed after that date. Its operation in a particular historical case depends on the statutory facts and applicable judicial interpretation.
Income-tax Act, 2025: Section 426
The Income-tax Act, 2025 came into force on 1 April 2026. Section 426 is titled Interest on excess refund and retains the 0.5% monthly or part-month rate. It refers to refunds under Section 270(1) and provides for adjustment following specified subsequent orders. Section 426(3) addresses first assessments under Section 279.
The older Section 234D remains relevant to assessment years and proceedings governed by the Income-tax Act, 1961, subject to repeal, savings and transition rules. Do not automatically substitute a 2025 Act section number in an order relating to an earlier year.
