Summary of this article
ITR refund amount becomes final only after CPC processing
TDS mismatches in Form 26AS can reduce tax refunds
AIS income differences or old demands may alter refund credit
Taxpayers should read Section 143(1) intimation before responding
A tax refund estimated at the time of filing may look reassuring after a taxpayer adds up Tax Deducted at Source (TDS), advance tax, and deductions. But the figure in the Income Tax Return (ITR) is only a claim. It becomes payable only after the Income Tax Department processes the return.
A smaller credit in the bank account does not automatically mean the refund has been wrongly withheld. The Centralised Processing Centre (CPC) may recalculate the tax position using information available in its system and make adjustments allowed under the law.
The ITR Figure Is Not The Final Refund
While processing a return under Section 143(1), the department checks the income, deductions, tax payments and credits declared by the taxpayer against Form 26AS, the Annual Information Statement (AIS), the Taxpayer Information Summary (TIS) and challan records.

A mismatch in TDS is one of the most common reasons for a reduced refund. An employee or depositor may claim tax deducted by an employer or bank, but the credit could be missing, lower or wrongly reported in Form 26AS. The CPC may then allow only the credit reflected in its records.
The final refund can also change when interest income, capital gains or another taxable receipt has been left out of the return but appears in the AIS. Arithmetical errors, an incorrect claim evident from the return, or interest charged under the tax law can alter the calculation, according to a recent report by Mint.
An outstanding demand from an earlier assessment year can have a separate effect. The department may set off the present refund against it after the prescribed process, leaving only the balance, if any, for the taxpayer.
Read The Processing Intimation First
Start with the intimation issued under Section 143(1). It compares the figures in the ITR with the department’s computation and should reveal whether the gap came from income, deductions, tax credits, interest or an earlier demand.
Cross-check the intimation with Form 26AS, AIS, TIS, salary documents, bank interest certificates and tax-payment challans. Where the problem is a TDS entry, the employer, bank or other deductor may need to correct its statement.
Respond To The Actual Issue
Where the department’s calculation contains a mistake apparent from the record, a rectification request can be filed after the return is processed. This route is for an obvious processing error, not for adding a new deduction or making a fresh claim.
Where a refund has been adjusted against an old demand, check the demand details and respond on the e-filing portal if there is a valid basis to disagree. Keep supporting records, including challans and earlier orders, ready.
The practical safeguard is to reconcile every income and tax-credit entry before filing. It takes more time at the start, but can prevent a surprise when the refund is finally credited.
FAQs
Why is my income tax refund lower than the amount claimed in my ITR?
The CPC may revise the refund after matching your return with Form 26AS, AIS, TIS and tax-payment records. TDS mismatches, omitted income, interest, or old tax dues can reduce the final amount.
Can my current refund be adjusted against an old tax demand?
Yes. The Income Tax Department may set off a refund against an outstanding demand from an earlier assessment year after following the prescribed process.
What should I do if I believe my refund has been calculated wrongly?
Check the Section 143(1) intimation against Form 26AS, AIS, TIS and challans. You may file a rectification request for an apparent error or dispute an incorrect old demand on the e-filing portal.
