Key requirements
File outstanding F5 or F8 through myTax Portal and retain the generated acknowledgement and payment advice. Check that the approver submitted the return rather than leaving a preparer’s draft. Then review Account Summary for the revised tax and penalties, and pay the displayed balance using GIRO or the stated payment slip. Do not treat an estimate as cancelled merely because someone began a draft. This page contains an older description of monthly filing penalties; the current late-filing page states S$200 immediately after the deadline plus subsequent completed months. Use the current penalty notice and late-filing guidance to reconcile charges.
