Once you are on GIRO payment scheme, your instalment payment for your taxes will continue in May each year to April of the following year, based on a Provisional Instalment Plan (PIP). 

Your PIP is computed based on your tax payable for the previous Year of Assessment (YA). The PIP allows you to enjoy the maximum 12 months instalment. 

The tax instalments will be revised subsequently when your current tax bill is finalised. The tax instalments that you have paid will be used to offset your tax assessed and the instalments for the remaining months will be adjusted accordingly.

Excess payment, if any, will be automatically refunded to you. There is no need for you to make a claim for refund.

If you wish to revise the PIP to an amount that is close to your actual tax payable, please chat with us online.

Generally, most taxpayers should receive their tax bills, also known as Notice of Assessment (NOA), from end Apr 2024 to end Sep 2024. As IRAS sends out tax bills in batches, some taxpayers may receive them earlier than others. 

If you have updated your Singapore mobile number with IRAS, you will receive an SMS alert when your tax bill is finalised. To update your mobile number, log in to  myTax Portal using your Singpass or Singpass Foreign user Account (SFA), and click on 'Update Contact & Notification Preferences'.

You need to check and ensure that your income details and relief claims are accurate in your tax bill. If you have any other income that is not shown in your tax bill or if your relief claims (including those that are prefilled) are incorrect, please inform IRAS of any discrepancy through the 'Amend Tax Bill' digital service in myTax Portal within 30 days from the date of your tax bill.

You may use the 'Amend Tax Bill' digital service at  myTax Portal to file an objection for any of the following purposes:

1. Revise income declaration;
2. Add or amend claims for deductions and reliefs;
3. Claim Parenthood Tax Rebate; or
4. Change in tax residency status (non-resident to resident, if applicable).

This digital service allows you to easily view the pre-filled values in the original tax assessment and make amendments. Thereafter, you will be able to see a consolidated view of the revised income, deductions and reliefs and receive an instant acknowledgement upon submitting the objection. We will issue the revised tax bill (digital/paper) or provide an update on the status of your objection within 10 working days.

Please contact your employer directly to seek clarification. If there are subsequent amendments, your employer will transmit details of the amendments to IRAS. IRAS will send you the revised tax bill accordingly.

Income tax is payable within 1 month from the date of your tax bill. You may pay your tax via GIRO, AXS station or Internet Banking. Majority of our taxpayers pay their taxes by GIRO. Find out more about the different payment modes.

If you are facing financial difficulties, you may request for a longer payment plan via the 'Apply/Manage GIRO Plan' digital service at myTax Portal using your Singpass upon receiving your tax bill, if you are under GIRO.

GIRO is a fuss-free mode of paying your tax. You may choose to pay by monthly interest-free GIRO deductions (up to 12 months) or one (yearly) GIRO deduction. Find out more about GIRO.

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, please register for PayNow NRIC/FIN to receive your refund.
