1. The Big Change: Income Tax Act 2025 vs. 1961

India’s Income Tax Act, 1961 has governed taxation for over 64 years, but it’s being repealed and replaced with the Income Tax Act, 2025 starting April 1, 2026. This change simplifies the tax structure and introduces a unified "Tax Year" concept instead of the "Assessment Year" and "Previous Year" system.

Key Changes:

• The Income Tax Act, 2025 will be the new governing law, streamlining the process and simplifying tax administration.
• The "Tax Year" concept replaces the old Assessment Year/Previous Year distinction, making it easier for businesses and individuals to track their tax liabilities.

2. Updated Income Tax Slabs for FY 2026-27 (AY 2027-28)

The Budget 2026 introduces new income tax slabs under the new tax regime. These slabs are designed to provide greater relief to taxpayers and reduce the tax burden, especially for the salaried class.

New Income Tax Slabs (New Regime) for FY 2026-27 (AY 2027-28):

• Up to ₹4 Lakh: Nil
• ₹4 Lakh – ₹8 Lakh: 5%
• ₹8 Lakh – ₹12 Lakh: 10%
• ₹12 Lakh – ₹16 Lakh: 15%
• ₹16 Lakh – ₹20 Lakh: 20%
• ₹20 Lakh – ₹24 Lakh: 25%
• Above ₹24 Lakh: 30%

Additionally, Standard Deduction has increased to ₹75,000 (previously ₹50,000). The effective tax-free limit for salaried individuals is now ₹12.75 Lakh (₹12 Lakh rebate + ₹75,000 standard deduction).

3. GST: The 30-Day Rule & E-Invoicing Expansion

The GST system has undergone some important updates in 2026. One of the most significant changes is the mandatory e-invoicing and the introduction of the 30-day reporting window.

Key Changes:

• E-Invoicing is now mandatory for businesses with an annual turnover of ₹5 Crores and above. The strict 30-day rule applies to businesses with an AATO (Aggregate Annual Turnover) above ₹10 Crores. This rule means that invoices must be uploaded within 30 days, or they will become invalid for claiming Input Tax Credit (ITC).
• For businesses in the ₹5 Crore–₹10 Crore bracket, even though the 30-day rule does not yet apply, it is advised to adopt the habit of uploading invoices within 30 days, as the threshold may be lowered in the future.

This presents a major opportunity for CAs to guide clients through the e-invoicing transition, ensuring compliance and maximizing ITC benefits.

4. Buyback Taxation Change

Another significant tax reform in 2026 concerns buybacks. In previous years, buyback taxes were paid by the company, but under the new rules, the tax is now levied on shareholders as Capital Gains Tax.

Key Points:

• Proceeds from buybacks are now taxed as capital gains in the hands of shareholders, with tax rates of 12.5% for Long-Term Capital Gains (LTCG) and short-term capital gains tax applying based on holding periods.
• Promoters will face an effective tax rate of 30%, which is a significant change to prevent tax arbitrage.

For CAs, this means you’ll need to adjust your tax planning strategies for clients involved in buybacks, ensuring they are aware of the higher tax burden on promoters and shareholders.

5. Corporate Mitras: A New Opportunity for CAs

In 2026, the government introduced “Corporate Mitras”, a new group of professionals dedicated to assisting MSMEs with compliance and taxation matters. While Corporate Mitras will help MSMEs with basic tax functions, there’s still a great opportunity for CAs to offer strategic tax advisory and advanced services.

What This Means for CAs:

• CAs can position themselves as strategic partners for MSMEs, offering high-level advisory services that Mitras may not cover.
• This shift presents an opportunity to expand your client base and offer value-added services beyond basic tax filing and compliance.

6. MAT Reduction: From 15% to 14% and Final Tax

The Minimum Alternate Tax (MAT) rate has been reduced from 15% to 14%, but it’s now classified as a final tax for companies in the new regime.

Key Changes:

• MAT Credit set-off is only allowed for companies that shift to the new regime and is capped at 25% of the tax liability per year.
• This will require CAs to provide detailed tax planning advice to clients on how to adjust their accounting and maximize MAT credit benefits while transitioning to the new regime.
