Basic Corporate Tax Calculator
The Basic Corporate Tax Calculator is an excel workbook intended to help companies and tax agents prepare tax computations and tax schedules when filing their tax returns. It includes explanatory notes to guide taxpayers through their tax computations and validation checks against common errors.
Purpose of the Basic Corporate Tax Calculator (BTC)
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.
Trading vs. Investment Holding Companies
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 (PDF, 540KB).
