Updated Return _ Deduction

Yes, you can claim 80C and 80D deductions in a belated return (filed under Section 139(4)), but generally cannot claim these missed deductions in an updated return (ITR-U). A belated return allows for missed deductions, whereas ITR-U is designed only to report additional income and pay extra tax.

There are significant restrictions on selecting the tax regime when filing belated or updated return . You cannot opt for the Old Tax Regime in a belated return (u/s 139(4)) or an updated return (u/s 139(8A)) if you failed to make that choice by the original due date.

The updated return (ITR-U) under Section 139(8A) does let you include deductions you missed originally, but there is one key constraint: the filing must result in additional tax payable, not a reduced liability or refund. So if you missed an 80C deduction and your original return already showed a refund, ITR-U is not the right route. The provision is designed for disclosing missed income or correcting errors that increase tax.

For a clear walkthrough of what is and is not allowed in revised vs updated returns for AY 2026-27, this [belated and updated ITR guide](https://taxgarden.in/blog/belated-revised-updated-itr-return-guide-india-ay-2026-27) covers the rules section by section.

Deductions under Updated Return u/s 139(8A) can be availed if the tax liability is increased or else if there is no tax liability refund/reduction. If the deduction decreases your taxable income in your previously filed tax return or increases your refund, then an amended return cannot be done.

Also keep in mind that ITR-U is primarily designed to declare income if you do not have filed your previous returns or commit a mistake in filing your returns and pay the tax along with a 25%/50% additional tax liability u/s 140B.

Restrictions differ for belated and updated returns:

• Belated return (Sec 139(4)): deductions under 80C and 80D are allowed, but only under the old regime. For individuals without business income, the old regime can be chosen only in a return filed by the due date (Sec 115BAC(6)). A belated return is automatically under the new regime, where 80C and 80D aren't available. So effectively, no 80C/80D in a belated return (non-business cases).

• With business income: the old regime option is via Form 10-IEA by the due date. If filed in time, the belated return can follow the old regime and claim deductions.

• Updated return (Sec 139(8A)): it cannot reduce tax liability or increase a refund compared with the earlier return. It is only for offering additional income. You can't introduce new deductions to lower tax. The regime choice must follow the original return (or default new regime if none was filed by the due date).

• Form 10-IEA can be filed each year (if not opting out after the one-time switch-back for business income), but it must be filed before the due date under Sec 139(1).

• Under the Income-tax Act, 2025 (from tax year 2026-27), the same structure continues.

Yes, subject to the applicable tax regime and the conditions for each deduction. Under the new tax regime, Sections 80C and 80D deductions are generally not available; under the old tax regime, they may be claimed if eligible and supported by the required facts and evidence.

A belated return may be filed under either regime, subject to the rules applicable to that assessment year. An updated return (ITR-U) cannot be used to claim or increase a refund, or to reduce the tax liability reported in an earlier return; it is not a route to newly claim deductions that would create such a benefit. The applicable regime options also depend on the taxpayer’s status and whether the prescribed option was exercised on time.

For return preparation, the key checks are the assessment year, taxpayer type, prior return history, regime choice, and whether the proposed ITR-U increases tax payable. Manual tracking of these rules and supporting deduction details can be difficult; automation reduces repetitive work while keeping professional judgment in control.
