Income-tax Act 2025 for First-Time ITR Filers: Tax Year 2026-27 Checklist

Finin2min Tax Desk·June 2026·7 min readFIRST ITR

First-time filers in Tax Year 2026-27 will enter the tax system under a new Act. The basics remain familiar — income, deductions, TDS, tax payment and return filing — but the references, tax-year language and forms ecosystem need careful handling.

Start with the correct tax year

The Income-tax Act, 2025 applies from 1 April 2026 unless otherwise provided. For first-time filers, the first practical rule is to classify income by the correct tax year and then check the official e-filing portal and tax calendar for the return form and due date.

Old vs new regime decision

Do not choose the old regime only because deductions exist. Compare tax under both regimes using actual numbers. For many salaried first-time filers with limited deductions, the new regime may be simpler; for filers with HRA, home loan interest and large deductions, old-regime analysis may still matter.
