How an income tax refund works
A refund arises when the tax you've already paid during the year — through TDS, advance tax and self-assessment tax — is more than your actual tax liability for the year. When you file your ITR, the Income Tax Department reconciles the two and returns the excess to your pre-validated bank account.
Interest on refunds — Section 244A
If you're due a refund, the department also pays you interest on it. Under Section 244A, interest is 0.5% per month (6% per annum) on the refund amount. For refunds arising from TDS and advance tax, interest is generally computed from 1 April of the assessment year up to the date the refund is granted — provided you file your return on time.
When interest starts
For excess TDS/advance tax, interest runs from 1 April of the assessment year. File your ITR by the due date to keep the full interest window; a late return can shorten it.
How much you get
Interest is 0.5% per month (part of a month counts as a full month) on the refund due. It's added automatically by the department and is itself taxable in the year received.
How to claim your refund
There's no separate refund application — the refund is claimed by simply filing your income tax return correctly. Follow these steps to make sure it reaches you without delay.
Reconcile 26AS & AIS
Match every TDS entry and advance-tax challan against Form 26AS and the AIS so nothing you've paid is missed.
File your ITR
Report all income, claim eligible deductions and file the correct ITR form before the due date to preserve full 244A interest.
Pre-validate your bank
Refunds are paid only to a pre-validated bank account linked to your PAN. Validate it on the e-filing portal in advance.
e-Verify & track
e-Verify within 30 days of filing, then track status under "Refund/Demand Status" on the portal until it's credited.
Questions people ask
Short answers on Income Tax Refund Calculator. Tap a question to open it.
01How is an income tax refund calculated?
Total tax and cess on your income for the year, less TDS, TCS, advance tax and self-assessment tax already paid. A negative figure is your refund; a positive one is tax still to be paid before filing.
02Is interest paid on a refund?
Yes. Section 244A gives interest at 0.5% per month, generally from 1 April of the assessment year to the date the refund is granted, where the refund arises from TDS, TCS or advance tax. No interest is paid if the refund is less than 10% of the tax determined.
03How long does a refund take?
Most refunds are issued within a few weeks of the return being e-verified and processed under section 143(1). Delays usually come from a mismatch in bank details or an outstanding demand from an earlier year.
04Why has my refund not arrived?
The most common reasons are a bank account that has not been pre-validated, a name mismatch with the PAN, the return not being e-verified within the time limit, or an adjustment under section 245 against an old demand.
05Can I claim a refund for an earlier year I never filed?
Only by filing a belated or updated return within the permitted window, or by applying for condonation of delay under section 119(2)(b) where the claim is genuine and within the prescribed time.
