Who Must Register with ACRA in Singapore (Guide for Business Owners)
Let’s be real starting a business in Singapore is exciting, but the paperwork can feel like a maze. Somewhere between building your dream brand and serving customers, you start hearing acronyms like ACRA, IRAS, and BizFile+. Suddenly, the fun idea of “running your own business” turns into “Wait… do I need to register this?”
So, let’s make this simple. Here’s a clear, human explanation of who needs to register with ACRA, who doesn’t, and why it’s worth doing it right.
Why ACRA Exists and Why It Matters to You in Singapore
ACRA stamds for Accounting and Corporate Regulatory Authority is Singapore’s national regulator – think of ACRA as the “guardian of good business conduct.”
Every company, partnership, and most small business ventures in Singapore are registered under ACRA’s digital portal, BizFile+, which acts as a one-stop service for business registration and filings.
Simply put:
✅ If you’re making money on an ongoing basis, ACRA needs to know about it.
✅ If your business exists only under your full name, you may be exempt.
✅ If you plan to hire, apply for grants, or tender for projects registration isn’t optional; it’s essential.
Who Must Register with ACRA in Singapore
If you are carrying out any activity for profit on an ongoing basis, you must register your business with ACRA unless you fall under the exemption list.
That includes:
- Freelancers and consultants offering regular paid services
- Online shop owners (Shopee, Carousell, Lazada, TikTok Shop sellers)
- Cafe or retail shop operators
- Service-based businesses (cleaning, logistics, design, accounting, etc.)
- Startups and SMEs building brands, tech products, or import/export businesses
Essentially, if you’re earning consistently, not just once-off, you need to register.
The minimum age to register a business in Singapore is 18 years old.
Who Doesn’t Need to Register
ACRA provides exemptions for a small group of individuals:
- If you operate your business using your full name as per NRIC, you are exempt. Example: “Tan Mei Ling Freelance Baking.”
- If you operate with one or more partners using their full legal names, you are also exempt.
But remember, exemptions only apply if your business name exactly matches your NRIC name(s). The moment you add creative flair say, “Mei’s Bakes by the Bay” you’ll need to register it.
Why Registering Your Business is Worth It
Some new entrepreneurs hesitate to register, thinking it’s just more paperwork. But here’s what registration actually gives you:
- Trust and credibility. Your customers can verify your business on ACRA’s public database.
- Access to funding. Government schemes under Enterprise Singapore often require an ACRA-registered business.
- Eligibility for tenders. You can participate in public and private tenders that require registration proof.
- Intellectual property protection. A registered business can apply for trademarks and patents more easily.
- Separation of personal liability. If you set up a company or LLP, your personal assets are protected.
In short: registration turns your idea into a real, recognised business entity in Singapore’s ecosystem.
Choosing the Right Business Structure
When registering, you’ll need to decide how your business should be structured. ACRA recognises four main types:
- Sole Proprietorship / Partnership – Great for freelancers or small family-run businesses. Simple, but unlimited personal liability.
- Limited Partnership (LP) – One general partner (liable) and one limited partner (liability capped).
- Limited Liability Partnership (LLP) – Common among professionals (lawyers, consultants, accountants) who want flexibility and limited liability.
- Company – A separate legal entity (e.g., Pte Ltd). Ideal for growth, investment, and credibility.
If you’re unsure, a corporate services provider (like us) can guide you through the setup based on your goals, risk appetite, and budget.
Choosing a Business Name
Your business name is your first impression and it needs ACRA’s green light.
On BizFile+, you can check name availability before registration. Avoid names that are:
- Already taken by existing businesses (e.g., “Morning Caffeine Pte Ltd” vs “The Morning Caffeine LLP”)
- Vulgar, obscene, or offensive
- Similar to government bodies or protected names (e.g., “Temasek,” “Singapore Police”)
Pro tip: Keep your name clear, relevant, and professional. “ChilliCrab Digital” works better than “Crabby Crab Crabz SG”. The fee for name registration is $15, and once approved, your chosen name is reserved for 120 days.
What You’ll Need to Register
Depending on your business type, you’ll need:
- A Business or Registered Office Address – Can be your shop, office, or even your home (under HDB/URA Home Office Scheme).
- Residential Address – Every owner or director must submit one (for ACRA’s records).
- Contact Address – Optional but useful for privacy. It hides your home address from public records.
- Business Activity (SSIC Code) – You must select a primary and secondary business activity using the Singapore Standard Industrial Classification (SSIC) system.
- Owner/Partner/Director Details – Including NRIC/FIN numbers and nationality.
No P.O. Boxes allowed, ACRA requires physical addresses.
GST and Tax Obligations in Singapore
Once your business is up, taxation follows. Here’s the short version:
- GST registration is compulsory if your annual turnover exceeds S$1 million, or you expect it to.
- Voluntary GST registration is allowed, but starting 1 November 2025, new companies registering voluntarily must comply with the GST InvoiceNow Requirement (digital invoicing).
- Corporate Tax: Companies pay tax on profits at 17%.
- Personal Tax: Sole proprietors and partners are taxed at individual rates.
For full details, refer to IRAS.gov.sg.
How Long Does It Take?
In most cases, registering your business takes less than one day through BizFile+.
If your chosen name includes restricted words like school, finance, or medical, ACRA may refer it to a Referral Authority, such as the Ministry of Education or MAS. These cases can take 14–60 days for approval.
So if you’re planning to launch before the year-end, don’t wait till the last minute start early.
What Happens After Registration
Once your business is approved, ACRA will issue a Unique Entity Number (UEN), your official ID for all transactions, taxes, and grants. You’ll also receive login access to BizFile+, where you can manage filings, update details, or renew licences. It’s a milestone moment. Many entrepreneurs say the moment they get their UEN, it feels “real.”
A Friendly Word of Advice
Singapore’s business environment is efficient but strict. Failing to register when required can result in penalties or forced closure. And beyond the law, unregistered businesses risk missing out on credibility, trust, and growth opportunities. If you’re serious about turning your idea into a business, make it official.
