c 7. In recent times, the number of zero-tax companies and , companies paying marginal tax has grown, hence, vide the Finance (No.2) Act, 1996, levy of minimum tax on companies having "book profits" stood introduced. The scheme envisaged payment of minimum tax by deeming 30% of the book profits D computed under the Companies Act, as taxable income, in a case where the total income as computed under the provisions of the 1961 Act, is less than 30% of the book profit. The word "book profit" has been defined in Section 115JA(2) read with the Explanation thereto to mean the net profit as shown in the Profit E and Loss Account, as increased by the amount(s) mentioned in clauses (a) to (f), and as reduced by amount(s) covered by clauses (i) to (ix) of the Explanation. These may be called for the sake of brevity as "Upward and Downward Adjustments". From the above it is clear that Section 115JA is a self-contained Code F and will apply notwithstanding any provisions in the 1961 Act. In this case, we are concerned with Downward Adjustment, particularly clause (viii) which refers to the amount(s) of profits eligible for deduction under Section 80HHC, computed under Section 80HHC(3) but subject to conditions specified in Sections BOHHC(4) and BOHHC(4A).
