Learn the correct steps to file ITR in India<\/figcaption><\/figure>\n\n\n\n

A plain-language guide for salaried employees, freelancers, and SME owners \u2014 file your Income Tax Return for FY 2025-26 correctly, on time, without paying a rupee more than you owe.<\/p>\n\n\n\n

Every July, millions of Indian taxpayers rush to file their Income Tax Return \u2014 and every July, thousands of them make the same preventable mistakes: wrong ITR form, AIS mismatches, missed deductions, forgotten interest income, and the single most costly error of all \u2014 not e-verifying within 30 days of submission.<\/p>\n\n\n\n

For FY 2025-26 (AY 2026-27), there is an additional reason to pay attention. Budget 2026 introduced staggered filing deadlines for the first time, which means your deadline is no longer automatically July 31. Picking the wrong deadline for your income type can result in a late fee even if you file what you thought was on time.<\/p>\n\n\n\n

This guide covers everything: who needs to file, which form applies to you, what documents to gather, the step-by-step filing process, and the eight most expensive mistakes to avoid this season.<\/p>\n\n\n\n

ADVISORY<\/strong><\/p>\n\n\n\n

Important note on the Income Tax Act 2025<\/a>: The ITR you are filing right now \u2014 for FY 2025-26 \u2014 is still governed by the Income Tax Act, 1961. The new Income Tax Act, 2025 came into effect on 1 April 2026 but applies only from FY 2026-27 (Tax Year 2026-27) onwards. You do not need to use new section numbers or form references for this year’s filing.<\/p>\n\n\n\n
