For a company that has not opted for a concessional regime, on what base is minimum alternate tax computed under section 206 of the Income-tax Act, 2025?

Section 206(1) of the Income-tax Act, 2025 charges a company whose tax on total income falls below a percentage of its book profit to tax on that book profit; the Finance Act, 2026 set the rate at 14% from tax year 2026–27. Adjusted total income is the base of the alternate minimum tax that section 206 applies to persons other than companies.
