Basic Corporate Tax Calculator

The BTC is designed for companies to compute, on their own, the amount of taxes they have to pay. The BTC is also used by companies to prepare their tax computations and tax schedules when filing their taxes.

Companies filing Form C should submit their tax computations and tax schedules together with Form C. Companies filing Form C-S should prepare and retain their tax computations and tax schedules and submit them to IRAS only upon request.

The BTC is designed for trading companies. The tax schedules in the BTC are those commonly used by such companies, such as the renovation and refurbishment expense and capital allowance schedules.

The BTC is not designed for use by investment holding companies. Investment holding companies should refer to the "Basic Format of Tax Computation for an Investment Holding Company" (195KB).

 The Year of Assessment (YA) 2019 BTC for Form C-S and Form C will be available from May 2019.
