Key Requirements, Compliance Deadlines & How Assembly Works Supports You
Incorporating a company in Singapore is straightforward, but ongoing compliance is where most founders face challenges. From statutory filings to tax deadlines and regulatory obligations, missing a requirement can result in penalties, late fees, or unnecessary risk.
Below is an overview of what is required to incorporate a Singapore Pte. Ltd., the key compliance milestones, and how Assembly Works supports you at every stage.
1. Incorporation Basics (Singapore Pte. Ltd.)
What You Need to Incorporate
To set up a private limited company in Singapore, the following are required:
• At least one shareholder (individual or corporate)
• At least one director ordinarily resident in Singapore
• A company secretary (to be appointed within 6 months)
• A registered office address in Singapore
• Paid-up capital (minimum S$1)
• Declared business activities (SSIC codes)
• KYC documents for all shareholders and directors
Typical Incorporation Timeline
• 1–3 working days if documents and KYC are ready
• 3–5 working days for foreign shareholders or more complex structures
2. Immediately After Incorporation (Day 1–30)
Several post-incorporation steps are critical but often overlooked:
• Setup of statutory registers (members, directors, controllers)
• Issuance of share certificates
• Corporate bank account opening
• Appointment of company secretary (mandatory within 6 months)
• GST registration, where applicable (mandatory or voluntary)
3. Key Ongoing Compliance & Due Dates (Cheat Sheet)
A. Annual Compliance (ACRA)
Item Deadline
Annual General Meeting (AGM) Within 6 months after FYE
Annual Return (AR) Within 7 months after FYE
First AGM May be dispensed via written resolutions
First AR Still mandatory
Example:
FYE 31 December 2025 → Annual Return due 31 July 2026
B. Tax Compliance (IRAS)
Item Deadline
Estimated Chargeable Income (ECI) Within 3 months after FYE
Corporate Income Tax (Form C / C-S) 30 November (e-filing)
Year of Assessment (YA) Follows FYE
Even if the company is dormant or has no revenue, ECI and tax filings are generally still required unless specifically exempted.
C. GST (If Registered)
Filing Frequency Due Date
Quarterly GST Return 1 month after quarter-end
D. Employment & Payroll (If Applicable)
• CPF contributions: By 14th of the following month
• IR8A / AIS filing: By 1 March
• Work pass renewals: typically 6 months before expiry
4. Common First-Year Pitfalls
• Missing ECI filing because the company is newly incorporated
• Assuming no activity = no filing (this is incorrect)
• Forgetting Annual Return filing when AGM is dispensed
• Late appointment of a company secretary
• Poor or no bookkeeping, leading to tax and audit issues later
5. Practical Timeline Example (Typical SME)
Incorporated: March 2025
Financial Year End: 31 December 2025
• Apr–Dec 2025 → Monthly bookkeeping
• Mar 2026 → File ECI
• By Jun 2026 → AGM or written resolutions
• By Jul 2026 → Annual Return filing
• By Nov 2026 → Corporate income tax filing
