The provisions relating to tax on book profits, generally referred to as minimum alternate tax (Mat), were first introduced in the Income Tax Act, 1961 (the Act) by the Finance Act, 1987, wef assessment year 1988-89, vide section 115J. Section 115J provides that where in the case of a company, the total income as computed under the Act is less than 30% of its book profit, the total income shall be deemed to be an amount equal to 30% of the book profit.
As book profit can be computed only after the end of the year, a contention was raised by the assessees that in case tax is paid u/s 115J, the provisions relating to computation and payment of advance-tax are not applicable, and as a consequence, they are also not liable to interest under section 234B and 234C for non-payment/default and deferment of advance-tax.
This contention was not accepted by Guwahati, Madras, Madhya Pradesh and Mumbai High Court which took a view that even in cases covered by section 115J, the assessees are liable to pay advance-tax. Punjab and Haryana High Court took similar view in case of section 115JA (Mat provision for assessment years 1997-98 to 2000-01).
The rationale for arriving at such conclusion was, firstly, the expression current income, on which advance tax is payable u/s 207, refers to computation of total income under provisions of the Act which includes section 115J as well. Secondly, sections 234B and 234C do not exclude the applicability where tax is payable section 115J. Thirdly, an estimate of book profit can be made on basis of business projections and profit embedded in transactions effectuated during the year. Lastly, even prior to insertion of section 115J assessees have been estimating current income, after providing deductions admissible under the Act, and if they can do so, they can also estimate book profit.
However, a division bench of the Karnataka High Court in the case of Kwality Biscuits Ltd v CIT (2000) 243 ITR 519, held that advance-tax related provisions would not apply to tax payable under section 115J since the entire exercise of computing income under section
