There are 2 ways to pay taxes:
Companies registered in Singapore are advised to sign up for GIRO to take advantage of the installment payment of accrued tax.
If your company does not have an existing GIRO corporate income tax agreement, sign up for a GIRO at least 3 weeks before you file your ECI. The GIRO agreement must be approved before the due date (i.e., 1 month from the date of the notice of assessment) in order for your company to be eligible for payment in installments.
If the GIRO agreement is not approved before the due date, your company will have to pay the full amount of the assessed tax within 1 month of the date of the notice of assessment.
You can make your payment using electronic payment methods such as online banking, phone banking, and NETS. If your company is having trouble paying taxes, read about the support measures available.
