Prepare access and choose the filing service
For YA 2026, the page states a 30 November 2026 corporate income tax return deadline. ECI is generally due within three months after the financial year ends unless a waiver applies. Qualifying companies use Form C-S or C-S (Lite); dormant companies have a separate filing service. Prepare the company UEN, financial statements and tax computation. Tax agents should finish and submit one client’s return before opening another client’s filing window, as the page advises against simultaneous client filing sessions.
Applications and account follow-up
The directory includes Certificates of Residence, penalty-waiver requests, dormant-company filing waivers, cessation-related advance returns, GIRO and the company dashboard. A tax filing waiver or final tax return is separate from ACRA striking off. Service tables identify expected documents and processing estimates, including longer review for complex cessation applications. View assessments and notices after submission, and use the business tax-agent dashboard or secure correspondence channels for authorised client work.
