For the 2026 tax filing season (YA 2026), the filing due date for Individual Income Tax and Partnership Income Tax returns is 18 April 2026. IRAS no longer uses the old 15 April paper-filing deadline as the general current filing date.
If IRAS has informed you that you are on No-Filing Service, you generally do not need to file unless you have additional income or changes to report. Always check your filing requirement and the applicable deadline in myTax Portal because special circumstances may have different timelines.
