India's corporate tax system is a cornerstone of national fiscal policy and a key factor in shaping the country's investment climate. The past ten years have seen a profound shift from a labyrinth of complex exemptions toward a clearer, more efficient framework aimed at boosting competitiveness and economic expansion.

The timeframe spanning Assessment Years 2022-23 to 2026-27 marks a period of exceptional stability and deliberate policy direction. This era is anchored by the transformative 2019 reforms, which established a dual-tax system: a standard regime carrying forward older provisions and an optional alternative regime featuring substantially reduced rates, contingent upon the surrender of most deductions and incentives.
The following overview presents a detailed, annual analysis of the prevailing tax rates, their associated conditions, and effective outcomes, serving as a comprehensive resource for strategic corporate planning over this five-year period.
Key Note:
Assessment Year (AY) is the year in which the income of the Previous Year (PY) is assessed and taxed. For example, income earned in FY 2021-22 is assessed in AY 2022-23 .
The major structural change was introduced via the Taxation Laws (Amendment) Act, 2019 , which provided an optional lower tax regime for domestic companies.
Surcharge and Health & Education Cess are applied on the tax amount. The rates below are basic tax rates .

FAQs
How to opt for Section 115BAA reduced tax rate?
To avail of the 22% tax rate under Section 115BAA, a domestic company must irrevocably file Form No. 10-IC electronically before its income tax return deadline. This declaration commits the company to forgo specified deductions and most carried-forward losses, resulting in an effective tax rate of approximately 25.17% and exempting it from Minimum Alternate Tax (MAT) from that year onward.
