What should employees do if they have already declared their employment income and deductions, and their employers have also submitted their income information via the AIS?
If your employees have e-Filed their Income Tax Return, they may re-file their tax returns at myTax Portal (Individuals > File Income Tax Return) within 7 days of their previous submission or by 18 Apr, whichever is earlier.
If your employees have received their tax bill (i.e. Notice of Assessment), they may file an amendment using the 'Object to Assessment' digital service at myTax Portal within 30 days from the date of the tax bill.
