Monthly or bi-monthly instalments


For new companies, instalment payments must commence in the 6th month of the basis period for the year of assessment, i.e. payable in the 6th month after the company commences operations.

For existing companies, the estimated tax payable must be paid in equal monthly instalment from the second month of the basis period but before 15th of each following month.

A penalty of 10% will be imposed if the balance tax payable is not paid by the due date. An additional penalty of 5% will be imposed on the tax and penalty outstanding if the tax payable and penalty remained unpaid within 60 days from the due date.

However, an application to appeal can be submitted to Inland Revenue Board of Malaysia (IRBM) if the company does not agree with the late payment penalty imposed. This appeal must be made in writing within 30 days from the statement of account. Yet the tax liability need to be paid before any appeal to be made.
