After more than six decades, India's income tax law is being rewritten. The Income Tax Act, 2025 comes into force on 1 April 2026 and applies from Tax Year 2026-27 onwards, replacing the Income Tax Act, 1961. For most small businesses, the good news is simple: your tax rates are not changing — the law is just becoming easier to read and follow.
What is actually changing
The new Act is a structural clean-up. It cuts the law from over 800 sections to 536 sections across 23 chapters, removes decades of obsolete provisions, and uses plainer language. The core principles — how income is taxed, deductions, TDS — largely stay the same.
The big one: "Tax Year" replaces "Previous Year" and "Assessment Year"
This is the change you'll notice first. The confusing pair of "Previous Year" (when you earned) and "Assessment Year" (when you filed) is gone. From 1 April 2026 there is a single Tax Year running 1 April to 31 March. Income earned in that window is simply your Tax Year 2026-27 income.
What it means for FY 2025-26
Nothing changes for the current year. Income earned up to 31 March 2026 is still taxed under the old 1961 Act, and your ITR for FY 2025-26 (AY 2026-27) is filed under the old rules. The first filing under the new Act happens in 2027.
- Rates & slabs: unchanged — old and new regimes continue as they are.
- Compliance: simpler forms and clearer TDS rules are being notified.
- Action for now: nothing urgent — file FY 2025-26 as usual; we'll guide you through the transition.
Should small businesses worry?
No. Think of it as the same tax policy in a cleaner rulebook. The benefit for you is fewer interpretation disputes and simpler compliance over time. The one habit to build is getting comfortable with the "Tax Year" language.
