Received a letter or SMS about No-Filing Service (NFS)?

If you received a letter or SMS informing you that you have been selected for NFS, you are not required to file an Income Tax Return.

You can log in to myTax Portal using your Singpass or Singpass Foreign user Account (SFA) to verify that the auto-included information is correct and preview your tax bill from 1 Mar to 18 Apr. However, if you wish to make any adjustments to your income details or relief claims, you can select "Individuals" > "File Income Tax Return" to file your return at myTax Portal. Find out more on e-Filing your Income Tax Return. 

Your Notice of Assessment or tax bill (digital or paper format) will be sent to you from end Apr to end Sep. Please note that it is your responsibility to ensure that your tax bill is accurate. If you have any other income that is not shown in the tax bill, or if your relief claims in the tax bill are incorrect, you must inform IRAS of any discrepancy through the “Object to Assessment” digital service at myTax Portal within 30 days from the date of your tax bill.
