Income Tax Slabs in India for FY 2025-26 (AY 2026-27): Complete Guide to New vs Old Tax Regime

Introduction to Income Tax in India

Income tax is a direct tax levied by the government on the income earned by individuals and businesses. In India, a progressive tax system is followed, which means that tax rates increase as income increases.

For the Financial Year 2025-26, the government has introduced important updates to the income tax structure, especially under the new tax regime. While the new regime is now the default system, taxpayers still have the option to choose the old tax regime based on their financial situation.

This guide provides a complete understanding of income tax slabs, rebate rules, deductions, surcharge, and a detailed comparison between the two regimes.
