/ Section 115JB MAT core
The 15% alternative.
- MAT (Minimum Alternate Tax) applies to companies where tax under standard regime (25% / 22% / 30%) is LOWER than 15% of book profit.
- In that case: MAT at 15% + surcharge + cess = ~15.6% effective applies instead.
- Book profit = net profit per P&L adjusted for specific additions / deletions (Explanation 1 to Section 115JB).
- MAT credit: excess MAT paid over standard tax carried forward 15 years + can be set off against future years when standard tax exceeds MAT.
- Section 115BAA / 115BAB opt-in exempts from MAT: specific legislative design. Mature companies in 115BAA regime (22%) + new manufacturing in 115BAB (15%) are MAT-free.

The carve-outs.

/ Common Form 29B scenarios
Where it matters.
- Company in standard regime (25% / 30%) with substantial Section 10AA SEZ / Section 80 deductions - standard tax may be below 15% effective → MAT applies.
- Loss-making company with timing differences - book profit may still be positive while taxable income is negative.

FAQ
Common questions, answered.
Who needs to file Form 29B?
Every company liable to pay MAT under Section 115JB. If company's standard tax (25% / 30%) is lower than 15% of book profit, MAT applies + Form 29B mandatory. Companies that opted into Section 115BAA or 115BAB are exempt from MAT - Form 29B not needed for them.
What's the MAT rate for 2026?
15% of book profit + applicable surcharge + 4% cess = ~15.6% effective. (Rate was 18.5% pre-Finance Act 2019; reduced to 15% to encourage profitability-based taxation.)
Does Section 115BAA opt-in avoid MAT?
Yes - companies in Section 115BAA (22%) are exempt from MAT. One of the key benefits of 115BAA opt-in (alongside concessional rate). Companies with substantial MAT concern pre-opt-in see additional reason to switch to 115BAA via Form 10-IC.
What's MAT credit?
If MAT paid is higher than standard tax in a year, excess (MAT - standard tax) is MAT credit. Carried forward 15 years. In future years when standard tax exceeds MAT, MAT credit can be set off against standard tax (up to extent of standard tax). Prevents double-counting.
Does Form 29B need ICAI UDIN?
Yes - UDIN (Unique Document Identification Number) mandatory for every CA certificate signing. Generated on ICAI portal + attached to Form 29B. Non-UDIN Form 29B considered invalid.
Does BQP handle Form 29B + Section 115BAA opt-in modelling?
Yes - integrated. Pre-opt-in modelling: standard regime + MAT vs 115BAA + no MAT comparison. Form 29B signing if MAT applies. Form 10-IC filing for 115BAA opt-in. Standard annual engagement for Indian companies. WhatsApp +91 78018 87130.
