2026 Singapore Compliance Checklist:
Is Your SME Ready for the New Regulatory Era?

In 2026, businesses can no longer treat checklist compliance in Singapore as a “check-the-box” activity. In addition, with the full enforcement of the Corporate Service Providers Act and the removal of the long-standing “end-of-month” grace period for ACRA filings, regulators have removed the margin for error. As a result, SMEs must now take a proactive, calendar-driven approach rather than a reactive one.

Therefore, to help you navigate these changes, Mdm Chong SME Services has compiled the definitive 2026 Compliance Checklist for Singapore. This roadmap ensures you stay on the right side of ACRA and IRAS while maximizing the tax benefits introduced in Budget 2026.

As of January 2026, ACRA has eliminated the informal “buffer” that allowed companies to file by the end of the month. ACRA now calculates deadlines based on the exact calendar date.

• Annual General Meeting (AGM): You must hold your AGM within 6 months of your Financial Year End (FYE). If your FYE is June 15, your AGM must be held by December 15, no exceptions.
• Annual Return (AR) Filing: You must lodge your Annual Return within 7 months of your FYE.
  Warning: Late filing now triggers an immediate penalty of up to $600 per breach, and directors face increased fines of up to $20,000 for serious non-compliance.
• Register of Registrable Controllers (RORC): Ensure you update your RORC within 14 days of any changes in beneficial ownership. ACRA’s AI now flags inconsistencies between share transfers and RORC filings instantly.
• Nominee Director Disclosure: Under the April 2026 amendments, nominee directors must now declare their status in writing to the company.

Meanwhile, “Real-Time Reporting” defines the tax landscape in 2026.

• InvoiceNow Mandate (Effective 1 April 2026): All new voluntary GST registrants must now transmit invoice data directly to IRAS via the InvoiceNow network.
  Strategic Move: If you aren’t yet on InvoiceNow, onboard early to claim the $1,000 SME Onboarding Grant before it lapses.
• Estimated Chargeable Income (ECI): File within 3 months of your FYE.
  Exemption: You qualify for exemption if your annual revenue is ≤ $5 million and your ECI is NIL.
• Corporate Income Tax (Form C-S/C): The deadline remains November 30.
  2026 Bonus: Ensure you apply for the 40% Corporate Income Tax (CIT) Rebate (capped at $30,000). If you employed at least one local in 2025, you are also eligible for a minimum $1,500 Cash Grant.

• AI Expenditure Audit: Under the Enterprise Innovation Scheme (EIS), track all spending on AI-powered SME accounting solutions. You can claim a 400% tax deduction on these expenses in 2026.
• Audit Exemption Check: Confirm if you still qualify as a “Small Company” (Revenue < $10M, Assets < $10M, < 50 employees). If you’ve grown past these marks for two consecutive years, you must prepare for a statutory audit.
• Registered Office Accessibility: Your office must be open and accessible to the public for at least 3 hours during ordinary business hours. P.O. boxes remain strictly prohibited.
