The MAT Overhaul: Finance Bill 2026 Analysis
Why the 1% rate cut is a trap—and how to save your accumulated tax credits.
The End of an Era
The Finance Bill 2026 has introduced the most significant corporate tax amendment of the decade: a complete restructuring of the Minimum Alternate Tax (MAT).
Under Clause 50 (Section 206 ITA 2025), the government is sending a clear signal: Move to the New Regime or lose your credits. For years, MAT was a safety net—you paid it, accrued credit, and set it off later. That mechanism is now being dismantled.
🚨 Fast Facts: The New Landscape
- Rate Cut: Reduced from 15% to 14%.
- Credit Freeze: No new credit generation allowed.
- Utilization: Old credits usable ONLY in New Regime.
- The Trap: Domestic companies capped at 25% set-off per year.
1. Old vs. New: What Changed?
The MAT Rate
A 1% reduction on Book Profits to sweeten the deal.
Credit Generation
MAT paid in Old Regime is now a Final Tax. Sunk cost.
Set-off Rules
You must switch to Sec 200/201 to use old credits.
2. Practical Example: The “25% Cap” Impact
Why you must calculate carefully: Even with credits, you cannot wipe out your tax liability instantly.
