Frequently asked questions
What professional indemnity insurance is required?
Many professional bodies mandate professional indemnity insurance as a condition of the practising certificate. Minimum coverage amounts vary by profession.
Are there continuing professional development obligations?
Most professional bodies require annual CPD hours or structured learning as a condition for renewing the practising certificate.
What entity structure is typical for professional firms?
Professional firms may operate as sole proprietorships, LLPs, or companies. Some professions restrict permitted entity structures. Check with the respective professional board.
Do I need a professional practising certificate?
Accountants, lawyers, architects, engineers, and other regulated professionals need a practising certificate from their respective professional body (e.g., ISCA, Law Society, BOA, PEB).
What is SSIC and why does it matter?
The Singapore Standard Industrial Classification (SSIC) is the national system for categorising business activities. It is mandatory at ACRA registration and is used by IRAS, MOM, and other government agencies for tax, licensing, statistical, and policy purposes.
Do I need to register with this SSIC code?
Every business entity registered with ACRA must select at least one SSIC code that best describes its principal economic activity. You can declare up to two codes — one primary and one secondary — via BizFile+.
