The Basic Corporate Tax Calculator is designed for trading companies and it comes with commonly used schedules such as the capital allowance schedule. You can use the Tax Calculator to prepare your company's tax computation and work out the tax payable.
If you are filing Form C, please submit your tax computation and supporting schedules with Form C.
If you are filing Form C-S, the company’s tax computation and supporting schedules are not required to be submitted together with Form C-S. They are to be retained and submitted only upon IRAS’ request.
