Section 431 of the Income-tax Act, 2025 — Entitlement to Income-Tax Refund

In plain language

What Section 431 says in plain English

Section 431 is the foundation stone of the refund system under the new Income-tax Act, 2025. It gives you a legal right to a refund whenever the tax paid by you (or on your behalf, or treated as paid on your behalf) for a tax year is more than the tax you are actually liable to pay for that year. In short: if the government has collected more of your money than the law entitles it to keep, that excess belongs to you and must be returned.

The exact statutory idea is: "If any person satisfies the Assessing Officer that the amount of tax paid by him or on his behalf or treated as paid by him or on his behalf for any tax year exceeds the amount with which he is properly chargeable under this Act for that year, he shall be entitled to a refund of the excess." This is the successor to Section 237 of the old Income-tax Act, 1961, carried into the 2025 Act with the same principle but simpler drafting.

Which payments count as "tax paid"

The "excess" is measured against everything credited to your account during the year. This typically includes:

• TDS (Tax Deducted at Source) — deducted by employers, banks, tenants or clients.
• TCS (Tax Collected at Source) — collected on certain purchases and remittances.
• Advance tax — instalments you paid during the year.
• Self-assessment tax — any tax paid at the time of filing.
• Amounts "treated as paid" — for example, TDS reflected in your Annual Information Statement even if the deductor delayed the challan.

When the sum of all these exceeds your final computed liability (after rebate under Section 156 and reliefs), the difference is refundable.

Who it applies to

• Every "person" as defined in the Act — salaried individuals, pensioners, freelancers, professionals, businesses, HUFs, firms, LLPs and companies.
• Salaried employees whose employer deducted TDS on a higher slab because they did not submit investment or deduction proofs in time.
• Senior citizens and small investors whose bank deducted TDS on interest even though their total income was below the taxable limit.
• Anyone who paid excess advance tax after later booking losses or claiming deductions.

Key conditions and limits

• You must file a return. Section 433 makes the income-tax return itself the vehicle for claiming a refund — there is generally no separate refund application. No return, no refund.
• The claim must be genuine and provable. The Assessing Officer must be "satisfied" that excess tax was paid; your Form 26AS / AIS and TDS certificates are the proof.
• Time limit. A refund claim is ordinarily made by filing the return within the due date; belated and updated returns have their own windows, and delayed claims may need condonation under the CBDT's powers.
• Special claimants. Section 432 allows a legal representative, guardian, trustee or receiver to claim a refund where the taxpayer cannot (death, incapacity, or income clubbed in another person's hands).

How it interacts with related sections

• Section 432 — decides who may claim in special cases (clubbing, death, incapacity).
• Section 433 — the form and limitation: refund is claimed through the return.
• Section 435 — refunds that arise after appeal or revision orders reduce your liability.
• Section 437 — interest on delayed refunds at 0.5% per month (6% per year) or part of a month.
• Section 438 — lets the department set off your refund against other tax dues, or withhold it in certain scrutiny situations.

Practical implications for you

Section 431 means an over-deducted salary, a wrongly-deducted TDS on FD interest, or an over-estimated advance tax instalment is never lost — it comes back to you, and if the department is slow, it comes back with interest. The single most important practical step is to file your return, because that is what activates your Section 431 entitlement. Always reconcile the refund shown in your return with your AIS/26AS to avoid a mismatch that delays processing.
