What is Income Tax Act 2025?
The old Income Tax Act of 1961 was written over six decades ago. Since then it had been amended hundreds of times, adding layers of complexity, confusing cross-references, and outdated provisions. which resulted in law becames nearly impossible for an ordinary taxpayer to read without professional help.
The new Income Tax Act 2025 does not introduce new taxes or remove existing deductions. Instead, it rewrites everything in simpler language using tables, formulas and clean structure that reduces section count from 819 to 536.
Key point:Β The tax rates, slabs, and deductions remain the same. What changes is how clearly the law is written and several specific rules that have been updated to be more practical and taxpayer-friendly.
Change #1: βTax Yearβ replaces financial year & assessment year
One of the most confusing things in Indian taxation was having two separate year concepts: the Financial Year (year in which you earn your income) and the Assessment Year ( year in which you file your return for that income). These terms cause lot of confusion, especially when filling ITR forms.
New Act removes this confusion; there is now just one term theΒ Tax Year. A tax year is 12-month period in which you earn your income, and your return is filed for that same Tax Year. This means when you file your income return earned in April 2026 to March 2027, you will simply call it Tax Year 2026β27. No more tracking which AY corresponds to which FY.
