A company elects to pay additional income-tax under section 170(5) on ₹300 lakh of unrepatriated excess money. How much is the base tax before surcharge and cess?

Section 170(5) of the Income-tax Act, 2025 lets an assessee who has not repatriated excess money within the prescribed time pay additional income-tax at 18% on it, as a final payment; 18% of ₹300 lakh is ₹54 lakh. ₹62.8992 lakh is the same tax after a 12% surcharge and 4% cess, which the question excludes.
