The tax year starts on 1st April. The assessment to profits tax is provisional and is based on the previous year's assessable profits with 75% of the assessment being due by the 3rd quarter and the final 25% being due at the year-end. Tax payments delayed less than 6 months are subject to a 5% non-deductible surcharge whereas payments overdue by more than 6 months are subject to a 10% non-deductible surcharge. A tax credit is granted where the previous year's assessment exceeds the currents year's assessable profits.
