Running a company in Singapore comes with clear compliance milestones every year. Missing these deadlines can lead to penalties or administrative headaches, but keeping track doesn’t have to be complicated. This 2025 compliance calendar outlines the key ACRA (Accounting and Corporate Regulatory Authority) and IRAS (Inland Revenue Authority of Singapore) dates every SME owner should know — so you can plan ahead, stay compliant, and focus on growth.
At the beginning of the year, review your company’s previous financial year-end (FYE) and prepare for reporting deadlines. January is also the best time to confirm your bookkeeping is up to date and ensure all business expenses and invoices are recorded correctly.
By 1 March, employers must submit Form IR8A and related appendices to IRAS, declaring employees’ income for the preceding year. Companies under the Auto-Inclusion Scheme (AIS) must e-file these forms to ensure accuracy and compliance.
If your FYE falls between October and December 2024, this quarter is when you’ll prepare to file your Estimated Chargeable Income (ECI) — due within three months after FYE.
For companies whose financial year ended in January to March 2025, ECI filing should be completed by June. Even if your company did not make a profit, you must still submit a Nil ECI, unless IRAS has granted exemption.
During this period, most private companies also begin preparing for their Annual General Meeting (AGM). Under ACRA rules, AGMs must be held within six months after the FYE. At the AGM, directors present financial statements, auditors’ reports (if applicable), and shareholder resolutions for approval.
It’s also the perfect time to review employee records, contracts, and CPF submissions for compliance with MOM requirements — ensuring your internal HR and finance systems stay aligned.
Once the AGM is completed, the company must file its Annual Return (AR) within seven months after the FYE. This means that if your financial year ended on 31 December 2024, your AR is due by 31 July 2025.
The AR submission updates ACRA on your company’s particulars, such as registered address, directors, shareholders, and financial statements. Most companies must file these financials in XBRL format using ACRA’s BizFile+ system.
Dormant companies and small Exempt Private Companies (EPCs) may qualify for simplified filing or exemption, but they must still submit the AR to remain in good standing. Keeping digital financial records and using AI bookkeeping tools like ccMonet makes this process fast and error-free.
The final quarter of the year is all about corporate tax filing. Companies must submit their Form C-S or Form C — along with supporting financial statements and tax computations — by 30 November (paper filing) or 15 December (e-filing).
Form C-S is a simplified version for small companies with annual revenue of S$5 million or less, while Form C is used by larger or more complex entities that claim special deductions or reliefs.
After submission, IRAS will issue a Notice of Assessment (NOA). Companies can make payment through GIRO in monthly installments to manage cash flow more smoothly.
This is also a good time to review financial performance and prepare for the upcoming year’s compliance tasks, ensuring your 2026 filings are even more efficient.
Throughout the year, there are smaller but equally important tasks that require regular attention:
Consistent bookkeeping ensures these deadlines are met without last-minute stress.
