For Singapore small business owners, keeping track of statutory filing deadlines is essential for smooth operations and regulatory compliance. Understanding corporate tax, ACRA annual returns, GST, and payroll obligations is a key part of accounting services in Singapore, helping businesses avoid penalties, manage cash flow, and plan effectively for growth.
This guide provides a detailed, practical roadmap for 2026 deadlines and explains how proper accounting practices make compliance manageable.
Corporate tax compliance is fundamental for business continuity. Missing deadlines can lead to penalties, interest, and administrative complications.
Companies must submit their ECI within three months of their financial year-end (FYE).
Example: A 31 December 2025 FYE → ECI due 31 March 2026.
Companies meeting certain criteria (e.g., revenue ≤ S$5 million and nil chargeable income) may qualify for an ECI filing waiver.
Pro Tip: Organise accounting records monthly rather than only at year-end. Accurate books simplify ECI submission and help forecast estimated tax liabilities.
Full corporate income tax returns are due 30 November 2026 for Year of Assessment 2026, covering FYEs such as Jan–Dec 2025.
Ensuring all revenue, expenses, and allowances are correctly recorded before submission reduces the risk of errors or queries from the tax authorities.
Accounting Insight: Structured bookkeeping and reconciliations throughout the year make filing Form C efficient and reduces audit risks.
Maintaining ACRA compliance protects your company’s legal standing and reputation.
Unless exempted, a company’s AGM must be held within six months of FYE.
Unlisted companies: file within seven months of FYE.
Listed companies: file within five months of FYE.
Accounting Insight: Integrating AGM planning into your financial calendar ensures that AR filings are timely. Delays can trigger late fees and affect corporate credibility.

Jan–Mar: 30 April 2026
Apr–Jun: 31 July 2026
Jul–Sep: 31 October 2026
Oct–Dec: 31 January 2027
Accounting Insight: Consolidate GST reporting with bookkeeping systems to automatically generate reports and reduce manual errors.
CPF contributions and SDL must be submitted by the 14th of the following month.
Employment income reporting must usually be submitted by 1 March 2026 for the previous year.
Accounting Insight: Automated payroll systems linked with accounting records can streamline CPF calculations and reporting, reducing compliance risk.
