How do I get a refund for my tax credit?

You do not need to submit a claim for refund. More than 90% of the tax credits were refunded within 7 days from the date the credit arose.

Taxpayers who pay taxes through GIRO will receive refunds in the form of tax credits through the same GIRO account. If you are using another person's bank account for GIRO payments, refunds will be made to you through cheques. Please deposit the cheque into your bank account within the 3 months’ validity period.
