ACRA has no button that turns a sole proprietorship into a company. To convert a sole proprietorship to a private limited company in Singapore, register a brand-new Pte Ltd. Then move the business into it and cancel the old registration.
Most owners reach this crossroads after a growth moment. A bigger client asks for invoices under a company name, or a bank questions a personal account. A supplier's contract may also contain clauses that sting when your home backs the deal. A sole proprietorship is not a separate legal entity, so its debts belong to its owner, whether an individual, a company or an LLP.
The official cost of the switch is modest. In 2026, ACRA charges S$15 to reserve the new company name and S$300 to incorporate, and straightforward applications are often approved within 15 minutes. What needs planning is the housekeeping around the filing: licences, contracts, banking, GST and payroll.
Done in the right order, the change helps protect your contracts. It also reduces gaps in your licences or tax records. Some transfers still depend on the other party's agreement. In this blog, we compare the two structures and explain the step-by-step ACRA process and 2026 fees. We also explain what transfers, what must be re-applied for, and the duties that start once the company is live.

Why Convert a Sole Proprietorship to a Private Limited Company in Singapore?
A Pte Ltd is a separate legal person, so business risks generally stay with the company. This protection grows more valuable as you trade. Personal guarantees and breaches of directors' duties can still expose individuals to liability.
In practice, the owners we assist usually convert at a turning point. A consultant signs a larger retainer, a trader lands a distributor, or a jewelry business in Singapore wins its first department-store order. Each situation raises the same worry: what happens if something goes wrong now?
A Pte Ltd changes the answer. These are the four reasons that come up most often in our conversations with owners.
1. Your Personal Assets Come Off the Line
A private limited company owes its own debts. If a customer sues or a supplier is left unpaid, claims generally stop at the company's assets. This protection is not absolute. You can still be personally liable if you sign a personal guarantee or breach your directors' duties. For an individual sole proprietor there is no such line, and personal savings and the home can be reached.
2. Profits Move to the Corporate Tax Rate
For an individual owner, sole proprietorship profits are taxed as personal income, with marginal rates reaching 24%. Where the owner is a company or LLP, the tax treatment depends on its structure and, for an LLP, its partners. Company profits are taxed at IRAS's flat 17% corporate income tax rate, and qualifying new companies can claim partial exemptions in their early years only if they meet the eligibility conditions. Incorporation does not automatically reduce an owner's overall tax, because the comparison depends on the company's eligibility and on how much profit is drawn as salary or dividends.
3. Banks and Big Clients Prefer Companies
Tenders, procurement portals and lenders often prefer to deal with registered companies, though some will still contract with sole proprietors. A Pte Ltd can sign contracts, own assets and open corporate accounts in its own name, which simplifies both sales and financing.
4. The Business Gains a Life of Its Own
A company has perpetual succession, so it continues even if you retire or step back. Shares can be transferred to partners, family or investors, which makes fundraising and succession planning far easier.
How Does a Pte Ltd Differ from a Sole Proprietorship in Singapore?
A sole proprietorship is an extension of its owner; a Pte Ltd is a separate legal person with its own identity, obligations and lifespan.
Both structures register with ACRA via the GoBusiness start-up guide, but the mechanics diverge. A sole proprietorship has one owner, renews every one to three years, and ends when that owner stops trading. A company has shareholders, directors and a constitution, and it continues until it is wound up or struck off.
Eligibility differs too. A sole proprietorship may be owned by an individual, a company or an LLP; overseas owners must meet ACRA’s requirements, including appointing a locally resident authorised representative. Pass holders should check their eligibility with MOM; eligible Dependant’s Pass business owners can apply for a Letter of Consent. A Pte Ltd can be 100% foreign-owned, but it must appoint at least one locally resident director.
The switch is most common among owners who began with a home-based business. They now need a structure that can hold contracts, staff and investors. The table below sums up the practical differences.
Sole Proprietorship vs Private Limited Company in Singapore
| Feature | Sole Proprietorship | Private Limited Company (Pte Ltd) |
|---|---|---|
| Legal identity | No separate legal entity; the owner is the business | Separate legal entity with its own rights and obligations |
| Owner liability | Unlimited; business debts are owner's debts | Generally limited to the amount invested in shares |
| Ownership | One owner, locally resident or holding an eligible pass; companies/LLPs/overseas owners allowed | Up to 50 shareholders; foreigners may own 100% |
| Tax on profits | Applicable personal/corporate income tax rates, up to 24% at the top margin | Flat 17% corporate income tax, with exemptions for qualifying startups |
| Lifespan | May end when the owner retires, dies or stops renewing | Perpetual succession until wound up or struck off |
| Compliance | Renewal every 1–3 years; applicable tax filing | Company secretary, AGM, annual return and statutory registers |
| Setup cost (2026) | S$100 for one year or S$160 for three years | S$15 name application plus S$300 registration |
What to Prepare for Bizfile Company Registration
| Item | What ACRA Requires |
|---|---|
| Reserved name | Approved business entity name and its registration number from your S$15 name application |
| Directors | At least one locally resident director aged 18 or above, with NRIC or FIN, full name and date of birth |
| Registered office | A Singapore address, open to the public for at least three hours each business day |
| Shareholders and capital | At least one shareholder, with share capital and allotment details |
| Constitution | The ACRA model constitution or a customised version |
| Statutory registers | Nominee director, nominee shareholder and registrable controller details, unless exempt |
| Contact particulars | Mobile number, email, and residential and contact addresses for every position holder |
What Is the Step-by-Step Process to Change Business Structure with ACRA?
Reserve a new company name, incorporate the Pte Ltd through Bizfile, transfer the business across, then cancel the sole proprietorship — in that order.
ACRA's Bizfile guide lists everything you must prepare to register a local company, and the same route applies when you are converting. Work through the five steps below, gathering the Bizfile checklist in Step 2 before the incorporation filing in Step 3.
Budget a little time for endorsements and, if applicable, referral authorities. The sequence matters more than the speed, because cancelling the old registration too early can leave licences and contracts in limbo.
Plan for incorporation costs and first-year fees, and consider how to choose the right corporate service provider if you need help filing.
Step 1: Reserve the New Company Name
Apply for the business name first; ACRA cannot register a company without a reserved name. The application costs S$15 in 2026. You can usually keep the same trading name as your sole proprietorship if it is still available.
Note that the person who reserves the name must complete the registration and be appointed as a director or secretary of the new company. A corporate service provider can reserve and file on your behalf instead.
Step 2: Prepare the Details Bizfile Will Ask For
Gather everything before you start the transaction, because Bizfile times out incomplete sessions. The checklist above shows the essentials; prepare these details before you start the Step 3 incorporation filing.
Directors must be at least 18 years old, and the company needs at least one shareholder. Foreigners cannot self-file; ACRA requires a registered filing agent, such as a corporate service provider, to submit the application.
Step 3: Incorporate the Pte Ltd through Bizfile
With the details from Step 2 ready, this filing is the heart of the whole conversion. The registration fee is S$300 in 2026, payable by card or online banking, and ACRA's current fee schedule confirms the name and registration charges.
Most registrations are approved soon after payment, often within 15 minutes. Complex applications can take up to 15 working days, and referrals to other authorities can take 14 to 60 days. After you submit, the other relevant position holders must endorse the registration within 60 days unless a corporate service provider filed it for you. At payment you may also choose a special unique entity number rather than a sequential one.
If you are appointing a provider, our guide on how to choose the right corporate service provider in Singapore explains what to check first.

To have the incorporation and first-year compliance managed for you, contact SG Company Incorporation.
Step 4: Move the Business Into the Company
Most items need deliberate transfer, but employment contracts and related rights can transfer by operation of law when section 18A applies. Open the corporate bank account, address key contracts and update payroll before closing the old registration. Transfer each item deliberately:
- For assets: sign a written sale and transfer to the company.
- For staff: issue new or confirming employment terms so payroll and CPF continue under the company UEN. If the business is transferred as a going concern, existing employees may retain continuity and accrued service protections, so a fresh employment letter alone may not settle their entitlements.
- For outstanding liabilities: check which remain with the sole proprietor, which require creditor agreement to transfer, and which transfer by law, including applicable employment liabilities.
We set out exactly what moves and what must be re-applied for in the next section.
Step 5: Cancel the Sole Proprietorship Registration
Once contracts, licences and banking sit with the company, file cessation of the sole proprietorship through Bizfile. File a cessation notice within 14 days after you stop trading under the registered business name; ACRA processes the closure immediately.
Do this only after the new company is trading, so no licence or contract lapses mid-transition.
ACRA Fees for Incorporating a Company in 2026
| Transaction | ACRA Fee (2026) | Processing Time |
|---|---|---|
| Reserve the new company name | S$15 | Usually approved within 15 minutes |
| Incorporate the new Pte Ltd | S$300 | Most approved soon after payment; complex cases up to 15 working days; referrals 14 to 60 days |
| Alternate address per position holder (optional) | S$40 each | Filed during the application |
| Cancel the sole proprietorship | No fee | Filed through Bizfile once the transfer is complete |
What Happens to Your Licences, Contracts and Bank Account?
Most items need deliberate transfer: licences generally require re-application, contracts may need novation or re-signing, and the company opens its own bank account. Employment rights may transfer by law when section 18A applies.
This stage decides how smooth the change feels to customers and regulators. Plan it before you cancel anything, because some re-applications take weeks and some clients ask for updated paperwork.
Licences: Plan to Re-apply
Most licences name the registered business, so they cannot simply transfer to a company. A food licence, import registration or sector permit must be applied for again under the company's name. The issuing authority runs its own checks. In practice, we help clients overlap the applications so the new licence is in place before the old one is cancelled.
Contracts: Novate, Never Assume
Your existing customer and supplier agreements bind the sole proprietor, not the new company. Depending on the counterparty’s agreement, each contract may be novated to the company, replaced with a fresh agreement, or left with the sole proprietor. Novation replaces the old party with the company while keeping the terms intact, and it generally requires the other contracting party's written agreement. Switching silently can void warranties or breach exclusivity clauses, so notify clients and suppliers in writing.
Banking: Start Fresh Under the New UEN
Open a corporate account in the company's name and move GIRO arrangements, customer payment details and payroll across. Keep the personal account out of company transactions once trading begins under the company.
Tax and CPF: The Company Is a New Taxpayer
IRAS treats the company as a new entity with its own tax records. GST registration does not transfer. Check the transferred business’s turnover as well as the ordinary GST tests: if the company becomes liable on a going-concern transfer, apply within 30 days of the transfer. Under the prospective test, register within 30 days of the date you reasonably expect taxable turnover to exceed S$1 million in the next 12 months. Apply for a new CPF Submission Number under the company’s UEN and use it to make the required employee CPF contributions.
What Transfers and What You Must Redo
| Item | What You Must Do | Who You Deal With |
|---|---|---|
| Bank account | Open a new corporate account under the company UEN | Your bank |
| Licences | Re-apply; most are not transferable between entities | The issuing authority for each licence |
| Customer and supplier contracts | Novate or re-sign in the company's name | Your clients and suppliers |
| GST registration | Register the company separately once thresholds are met | IRAS |
| Employees and CPF | Continue payroll under the company UEN; s18A may apply | CPF Board and MOM where relevant |
| Business records | Move company registers and accounts into the company | ACRA, through your filings |
What Compliance Duties Start Once the Company Is Incorporated?
The company must appoint a secretary within six months and keep statutory registers. It must also file annual returns and hold an AGM unless exempt or the AGM is dispensed with. These duties differ from those of a sole proprietorship.
The paperwork load is the trade-off for limited liability, and it is manageable with reminders. Penalties are real: ACRA warns that failing to keep the registered office open for the required hours can draw a fine of up to S$5,000. Late annual returns attract composition fines as well. A company secretary helps manage compliance, and many small teams outsource company secretary services.
Your first-year duties include:
- Appoint a company secretary within six months of incorporation. Many small teams outsource company secretary services rather than hire in-house.
- Hold the first AGM within six months of the first financial year end, unless exempt or dispensed with. For most private companies, file the annual return with ACRA within seven months of that year end.
- Maintain the register of registrable controllers, plus any nominee registers, at the registered office.
- Register the company for GST within 30 days after the end of the calendar year in which taxable turnover exceeded S$1 million. Register within 30 days if you expect it to exceed S$1 million in the next 12 months.
- File corporate income tax returns with IRAS each year.
- Keep the registered office open to the public for at least three hours each business day.
Conclusion
The conversion is a sequence, not a single transaction. Do it in this order:
- Reserve the name.
- Incorporate the Pte Ltd.
- Transfer contracts, licences and banking.
- Cancel the old registration.
Done in order, the switch protects your contracts and reduces gaps in your compliance record. Each contract must be properly novated or re-signed if it is to transfer to the company; if it is not transferred, it may remain with the sole proprietor, depending on the counterparty’s agreement.
The ACRA side is quick and affordable. In 2026, it costs S$15 for the name and S$300 for incorporation. Most applications clear within minutes. The planning sits in the transfers: licences, contracts, GST and payroll.

Frequently Asked Questions
No. ACRA has no conversion transaction. You incorporate a new private limited company, transfer the business into it, and then cancel the sole proprietorship registration.
ACRA charges S$15 to reserve the company name and S$300 to incorporate the new company in 2026. Cancelling the old registration carries no ACRA fee. Corporate service provider fees, if you engage one, are additional.
The incorporation itself is usually approved within 15 minutes of payment. Complex applications can take up to 15 working days, and referrals to other authorities can take 14 to 60 days. Transferring licences and contracts adds further lead time.
No. Licences name the registered entity, so most must be re-applied for under the company's name. GST registration is entity-specific too, so the company must register separately. Apply within 30 days after the end of the calendar year in which taxable turnover exceeded S$1 million, or within 30 days if you expect it to exceed S$1 million in the next 12 months.
A company can be 100% foreign-owned, but foreigners cannot self-register. ACRA requires a registered filing agent, such as a corporate service provider, to submit the incorporation, and the company still needs at least one locally resident director.
