Explanation
Section 237 entitles a taxpayer to a refund if the tax paid (advance tax, TDS, TCS, self-assessment tax) exceeds the actual tax liability for the year. Section 238 defines who can claim: the assessee, their legal representative, or a principal in the case of agents. Section 239 requires that the claim is made within the prescribed period — generally by filing the income tax return within the due date; delayed refund claims may be time-barred. Section 244A provides for interest on refunds: at 0.5% per month (simple interest, 6% per annum). Where the return is filed on time, interest starts from 1 April of the assessment year; where the return is filed late, interest starts from the date of filing the return. No interest is payable on the first 10% of excess TDS or TCS refund to avoid frequent small refunds. Refund interest received from the Income Tax Department is taxable as 'Income from Other Sources' in the year of receipt — it is not exempt. Taxpayers should reconcile Form 26AS, AIS, and the ITR before expecting a refund, and use the refund re-issue facility on the portal if the refund fails due to incorrect bank details. Verify on the income-tax portal before filing.
