MAT Reduced to 14% from April 2026: What Companies Need to Know

For over two decades, MAT credit was a core tax planning tool for Indian companies. You paid the higher MAT today, carried forward the credit, and set it off against future regular tax liability. That system ends on 01 April 2026. The Finance Act 2026 has made MAT a final tax under the old regime - no new credit will be generated. To partially offset this, the MAT rate has been reduced from 15% to 14% of book profits.

This guide explains the new MAT framework, how existing credits can be utilised, whether your company should transition to the new regime, and the impact on financial statements and tax provisioning.

What Is MAT and Why Has the Government Changed It?

Minimum Alternate Tax (MAT) is a tax imposed under Section 115JB of the Income Tax Act, 1961 on companies whose regular tax liability is less than 15% (now 14%) of their book profit. It ensures that companies with high accounting profits but low taxable income (due to deductions, exemptions, or incentives) still pay a minimum level of corporate tax.

The Finance Act 2026 restructures MAT to push companies toward the new corporate tax regime (Section 115BAA at 22% or Section 115BAB at 15% for new manufacturing). By making MAT a final tax and allowing credit utilisation only in the new regime, the government is creating a clear financial incentive for regime transition.

Companies filing ITR for companies must now evaluate their MAT position carefully - the choice between staying in the old regime (with MAT as a dead cost) or switching to the new regime (where existing credits can still be used) has significant financial implications.

Key Terms You Should Know

• MAT (Minimum Alternate Tax): Tax at 14% (from TY 2026-27) of book profit imposed on companies whose normal tax liability is lower. Governed by Section 115JB of IT Act 1961.
• Book Profit: Net profit as per the P&L account under the Companies Act 2013, adjusted for specific additions and deductions prescribed in Section 115JB. Not the same as taxable income.
• MAT Credit: The difference between MAT paid and regular tax liability. Previously carried forward for 15 years and set off against future regular tax. From 01 April 2026, no new credit is generated under the old regime.
• Section 115BAA: Concessional corporate tax rate of 22% (effective 25.17% with surcharge and cess) for domestic companies. Companies under this section are not subject to MAT.
• Section 115BAB: Concessional rate of 15% (effective 17.16%) for new manufacturing companies incorporated after 01 October 2019. Also exempt from MAT.
• Final Tax: MAT paid under the old regime from TY 2026-27 is treated as the final tax - it cannot be recouped through credit mechanisms. The tax cost is terminal.
• 25% Set-Off Cap: Companies transitioning to the new regime can utilise existing MAT credit accumulated up to 31 March 2026, but set-off is limited to 25% of the tax liability in the new regime per year.

Which Companies Are Affected by the MAT Changes?

The MAT changes affect companies differently based on their current tax regime and credit position.

• Companies under the old corporate tax regime (25%/30% regular rates) who pay MAT when their normal tax falls below the threshold - MAT is now a final cost, not a timing difference
• Companies with large accumulated MAT credit balances (especially infrastructure, power, and SEZ units with tax holidays) - must decide whether to switch regimes to utilise credits
• Companies considering the transition from old to new regime - the 25% annual set-off cap means credit utilisation will take multiple years
• Foreign companies with India operations paying MAT - for foreign companies, MAT credit continues to operate as the delta between standard tax and MAT
• Companies already under Section 115BAA or 115BAB - not affected, as they were already outside MAT scope

Legal Framework: MAT Before and After Finance Act 2026

Note: The effective MAT rate including surcharge and cess is approximately 17.47% (14% + 12% surcharge + 4% cess) for companies with book profit above Rs 10 crore. The effective rate was approximately 17.47% at the old 15% rate for the same income bracket - the 1% rate cut saves approximately 1.17% in effective terms.

How to Evaluate Whether Your Company Should Switch Tax Regimes: Step-by-Step

1. Calculate your accumulated MAT credit balance as of 31 March 2026. This is the total MAT credit carried forward across all previous years. Check your ITR-6 (Schedule MAT) and balance sheet.
2. Estimate your tax liability under the new regime (Section 115BAA at 22%). Remove all deductions and exemptions that are not available under the new regime. Compute tax at the flat 22% rate plus surcharge and cess.
3. Calculate the annual set-off available - 25% of new regime tax liability. This is the maximum MAT credit you can utilise per year. Divide your total MAT credit by this annual set-off to estimate the number of years needed to exhaust the credit.
4. Check the remaining validity of your MAT credits. Each credit expires 15 years from the AY it was generated. If some credits are nearing expiry, time is critical - delaying the switch may cause credits to lapse.
5. Compare: old regime with MAT as final tax vs new regime with credit utilisation. Under the old regime, you pay MAT at 14% as a final cost (no recovery). Under the new regime, you pay 22% but utilise credits. Run a 5-year projection to determine the net present value of each option.
6. Factor in deductions you will lose under the new regime. Section 115BAA companies cannot claim deductions under 10AA, 80-IA, 80-IAB, etc. If your company has ongoing tax holidays, the cost of losing these deductions may outweigh the benefit of credit utilisation.
7. Consult your CA and finalise the regime choice before filing the ITR. The transition is irrevocable for most companies under Section 115BAA. File Form 10-IC before the due date of the ITR to opt for the new regime.

Documents and Records Needed for MAT Computation and Regime Transition

• Audited financial statements (P&L account, balance sheet) under Companies Act 2013
• Schedule MAT from previous ITR-6 filings showing accumulated MAT credit
• Tax audit report (Form 3CA-3CD) with book profit computation
• Form 10-IC - to opt for Section 115BAA new regime (irrevocable for most companies)
• Board resolution approving the regime transition - recommended for corporate governance
• Year-wise MAT credit register with AY of generation and expiry date (15-year limit)
• Deferred Tax Asset (DTA) workpapers - MAT credit is a DTA on the balance sheet; reversal impacts P&L
• Advance tax computation factoring in the new 14% MAT rate or 22% new regime rate
• IndAS/Ind AS 12 workpapers for deferred tax adjustments related to MAT credit write-off

MAT Credit Utilisation: How the 25% Cap Works

The following table illustrates how a company with Rs 10 crore accumulated MAT credit would utilise it after switching to the new regime.

Note: At 25% annual set-off, it takes 8 years to fully utilise Rs 10 crore in MAT credit (assuming constant tax liability). If any credit was generated more than 15 years ago, it will lapse before full utilisation. Companies must map credit expiry dates against the utilisation schedule.

Common Mistakes to Avoid in the New MAT Framework

Mistake 1: Assuming MAT credit can still be generated from 01 April 2026. No new MAT credit will accrue under the old regime. MAT paid is now a terminal cost. Companies must update their tax provisioning and DTA calculations accordingly.

Mistake 2: Trying to use MAT credit while staying in the old regime. From TY 2026-27, MAT credit set-off is available only in the new regime. Companies that remain in the old regime will see their accumulated credits lapse over time without any utilisation. Ensure proper tax audit services to review this transition.

Mistake 3: Ignoring the 25% annual cap on credit set-off. Even after switching to the new regime, credit utilisation is capped at 25% of tax liability per year. A company with Rs 20 crore in MAT credit and Rs 4 crore annual tax liability can only use Rs 1 crore per year - it will take 20 years, but credits expire in 15. This mismatch can cause significant credit loss.

Mistake 4: Not writing off lapsed MAT credit from the balance sheet. Under Ind AS 12, MAT credit recorded as a Deferred Tax Asset (DTA) must be written off when it can no longer be recovered. Failure to do so overstates assets and violates accounting standards.

Mistake 5: Confusing MAT (for companies) with AMT (for non-corporate taxpayers). Alternate Minimum Tax (AMT) applies to individuals, HUFs, partnerships, and LLPs under Section 115JC. AMT operates differently and is not affected by the MAT changes in Budget 2026.

Consequences of Not Planning for the MAT Transition

Companies that do not proactively plan for the MAT transition face several risks.

Under MAT as final tax, the 14% book profit tax is a permanent cost. If a company’s regular tax liability is lower (due to deductions like 10AA or 80-IA), the excess paid as MAT is lost forever. Previously, this excess became a credit - now it does not.

Under credit expiry rules, MAT credits lapse 15 years after the AY they were generated. A company that delays switching to the new regime may find that a significant portion of its accumulated credits has expired before it could utilise them.

Under Ind AS 12, companies must reassess their Deferred Tax Asset position. If MAT credits are no longer recoverable (because the company does not plan to switch regimes or credits are expiring), the DTA must be written down. This directly impacts net profit and shareholder equity in financial statements.

Additionally, companies that fail to adjust advance tax computations to reflect the new 14% MAT rate (instead of 15%) may overpay advance tax, creating unnecessary cash-flow pressure.

How MAT Connects with Corporate Tax Regimes, ICDS, and Financial Reporting

MAT’s book profit computation starts from the P&L account prepared under the Companies Act 2013 / Ind AS. Adjustments are made for items like deferred tax provisions, provisions for unascertained liabilities, and exempt income. The government has announced a Joint Committee of MCA and CBDT to integrate Income Computation and Disclosure Standards (ICDS) into Indian Accounting Standards from TY 2027-28, which will further simplify book profit computation.

For companies filing company registration and setting up new operations, the choice between old regime (MAT at 14% final) and new regime (22% under 115BAA or 15% under 115BAB with no MAT) must be made at incorporation. New manufacturing companies should strongly consider Section 115BAB at an effective rate of 17.16% - significantly lower than even the reduced MAT rate.

The interaction between MAT and the four corporate tax rate options (regular old regime, 115BAA, 115BAB, and old regime with MAT as final tax) creates a complex decision matrix. Companies must model 5-10 year projections to optimise their effective tax rate.

Key Takeaways

The Finance Act 2026 has reduced the MAT rate from 15% to 14% of book profit and simultaneously converted MAT into a final tax under the old corporate regime, effective from Tax Year 2026-27 onwards.

No new MAT credit will be generated from 01 April 2026. Companies staying in the old regime will treat MAT as a permanent, non-recoverable cost - a fundamental shift from the earlier credit-based system.

Accumulated MAT credits as of 31 March 2026 can still be utilised, but only by companies that switch to the new regime (Section 115BAA or 115BAB), and set-off is limited to 25% of tax liability per year within the 15-year carry-forward window.

Companies with large MAT credit balances - especially infrastructure, power, and SEZ units with tax holidays - should urgently evaluate whether transitioning to the new regime allows meaningful credit recovery before expiry.

All non-residents paying tax on a presumptive basis are now fully exempt from MAT, reducing cross-border tax friction and aligning with India’s strategy to attract foreign investment in sectors like electronics manufacturing and cruise tourism.

Need Help with Corporate Tax Planning After MAT Changes?

The MAT overhaul requires a full reassessment of your company’s tax strategy - from regime selection and credit utilisation planning to advance tax computation and financial statement adjustments. The 25% annual cap on credit set-off and the 15-year expiry window create a complex optimisation problem.
