As a Taxable Person registered for Excise Tax, you are required to file your Excise Tax Returns on a monthly basis. The due date to file your Excise Tax Returns is the 15th day of each month. Generally, when a registered Taxable Person is required to account for Excise Tax, the Taxable Person should submit the Excise Tax Declaration and reporting forms on a transactional or monthly basis as the case may be.
