Starting Your Business in Singapore

Published July 31, 2018 · Updated November 4, 2026

Can business formation in Singapore be completed in a day? Preparation can make the difference between a smooth application and a delay.

In this blog, we discuss entity choices, founder eligibility, name approval, costs and timelines. We also explain post-registration obligations and relevant 2026 support measures.

Which Steps Simplify Business Formation in Singapore?

Five stages — research, entity selection, name approval, registration and post-registration compliance — take a founder from an idea to a registered Singapore company.

A fast filing starts with decisions made before opening Bizfile. Use these five stages to separate registration requirements from commercial choices, then check the detailed comparison and deadlines below.

Step 1: Research the Market and Plan the Venture

Test demand, pricing, funding and the licences your activity may need. ACRA does not require a business plan for a standard company incorporation, although banks, investors or licensing authorities may ask for information separately.

Step 2: Choose the Entity That Fits the Venture

Compare personal liability, ownership, administration and future funding before choosing a structure. A company is not automatically the best fit for every venture; the comparison below explains the trade-offs.

Step 3: Clear and Reserve the Company Name

Apply for a name through Bizfile before registering the company. Check both business names and trademarks, as ACRA name approval does not itself protect a brand.

Step 4: File the Incorporation Application

Gather the proposed officers’ particulars, share details, constitution and controller information before filing. A complete application can be approved quickly, but referral or due diligence may take longer.

Step 5: Meet Post-Registration Obligations

Record the secretary appointment, corporate filings and tax deadlines immediately after incorporation. Also check licences and any obligations arising from hiring employees.

What Business Structures Can Founders Choose in Singapore?

A private limited company limits shareholder liability and permits full foreign ownership. Other structures may better suit a smaller venture or an overseas company's expansion.

Choose by asking who will bear debts, who will own the venture and how much administration it can sustain. The table compares common structures; the notes below explain the practical differences.

An overseas company may instead register a branch, which remains part of its parent, or establish a representative office for permitted market-research activities. A representative office is temporary and cannot earn income. A Singapore subsidiary is a separate local company and follows local company requirements.

1. Sole Proprietorship

One individual, company or LLP owns the business and is responsible for its debts. This can be simple for a small venture, but it does not create a separate legal entity. Business registration generally needs renewal every one to three years.

2. Partnership

A general partnership normally has two to twenty partners. Partners share the business and can be personally liable for its obligations. Discuss decision-making, contributions and exit arrangements before starting; the registration generally needs renewal.

3. Limited Liability Partnership (LLP)

An LLP has at least two partners and is a separate legal entity. A partner remains personally responsible for their own wrongful acts but is generally not personally liable for another partner’s wrongful acts solely because they are a partner. An annual declaration is required.

4. Private Limited Company (Pte Ltd)

A private company is a separate legal entity with one to fifty shareholders. Individuals and corporations may hold its shares, including through complete foreign ownership. Shareholders’ liability is generally limited to unpaid amounts on their shares, though personal guarantees can create separate obligations. The company must maintain records and meet continuing filing requirements.

Who Is Eligible to Incorporate in Singapore?

A private company needs an eligible resident director, a Singapore registered office, at least one shareholder and at least S$1 in share capital.

Requirements under the Companies Act 1967, administered by ACRA, apply to every applicant regardless of nationality. The core conditions are:

• At least one director aged 18 or above and eligible to act; an undischarged bankrupt needs permission from the court or the Official Assignee, with at least one director ordinarily resident in Singapore; foreign pass holders should check their eligibility and obtain any required permission before accepting the role.
• One to fifty shareholders, who may be individuals or corporations, local or foreign; complete foreign ownership is permitted.
• A company secretary appointed within six months: a natural person ordinarily resident in Singapore who is not the sole director.
• A registered office at a physical Singapore address, not a post-office box, and at least S$1 in share capital, which need not be fully paid up.

Foreign founders face two further rules. First, a non-resident cannot e-file the incorporation personally — ACRA requires submission through a registered filing agent such as a corporate services provider. Second, a founder who intends to relocate and run the company needs a work pass from the Ministry of Manpower (MOM), typically an Employment Pass or EntrePass, while a non-relocating founder must ensure the company has an eligible ordinarily resident director, who may be a business partner or a nominee.

On addresses, one misconception recurs: a prestigious location is not a legal requirement. The registered office must be a physical Singapore address, not a post box; since 20 October 2026 it has no minimum public opening hours, but company records must be available there for inspection for at least two hours on each relevant business day after reasonable notice; a residential address can qualify under the Home Office Scheme, subject to approval from the Housing and Development Board (HDB) or the Urban Redevelopment Authority (URA). In practice, most founders use a registered address service in a commercial building to keep the statutory record separate from home correspondence.

How Does Name Approval Work Before Incorporation?

An approved name costs S$15 to reserve and is held for up to 120 days. Some names require review by another authority.

ACRA screens proposed names against the register: identical names are generally rejected, while a similar name may still be subject to a complaint and a direction to change it. The name must also avoid prohibited words, must not infringe an existing trademark, and names suggesting regulated activity — banking or legal services, for instance — are referred to the relevant authority for clearance, which adds days to approval.

Two practical measures reduce the rejection risk. A preliminary screen with a free Singapore company name checker flags obvious clashes before any fee is paid, and a considered naming strategy — covered in our guide to selecting your Singapore company names — avoids sensitive and reserved words from the outset. Once approved, the S$15 reservation holds the name for 120 days, giving the founder time to assemble the incorporation documents.

What Does Registration Cost and How Long Does It Take in 2026?

ACRA charges S$315 in total for a name application and private company incorporation. Professional fees and other setup costs are additional.

The incorporation itself is an e-filing exercise: the constitution, director and shareholder particulars and their consents are submitted through Bizfile, and the certificate of incorporation is issued electronically on approval. The business formation process in Singapore runs entirely online, and in practice our team submits complete applications within an hour, with most registered on the same day — AI now cuts routine incorporation tasks down to minutes.

Speed assumes a clean name, complete identity documents and no referral. Applications with gaps, sensitive names or follow-up queries typically resolve within one to three working days, and foreign founders should allow additional time for the filing agent's customer due diligence.

Costs diverge on professional support. Local founders may self-file; foreign founders must engage a registered agent, and many bundle the filing, secretary and address into Singapore company incorporation services. Our step-by-step guide to Singapore company registration walks through each part of the submission.

What Obligations Follow Once the Company Is Registered?

A new company must appoint a secretary and track its ACRA and IRAS deadlines. Some tax filings and registrations depend on its circumstances.

Keep a calendar for ACRA and the Inland Revenue Authority of Singapore (IRAS). The deadlines below concern private companies; exemptions and different rules can apply. For a broader filing calendar, see our guide to Singapore company compliance.

Statutory Obligations and Possible Exemptions

The first appointments and filings deserve attention even if the company has little activity:

• Appoint a company secretary within six months. The sole director cannot be the secretary.
• Appoint an auditor within three months unless the company qualifies for an exemption. The small-company test has conditions, including group conditions where applicable.
• Maintain required company registers, including controller and nominee information unless exempt, and update ACRA when required.
• Generally file the annual return within seven months of financial year end for a private company. Different timing applies to a company with an overseas branch register.
• Generally file Estimated Chargeable Income (ECI) within three months of financial year end, unless a waiver or specific exemption applies.
• Generally file the corporate income tax return by 30 November of the relevant Year of Assessment (YA), unless a filing waiver applies.

IRAS grants an ECI filing waiver when annual revenue is S$5 million or less and ECI is nil before the relevant partial or start-up tax exemption. Both conditions must be met. Eligibility for Form C-S or Form C-S (Lite) also depends on IRAS’s conditions, not revenue alone.

For example, a company incorporated in 2026 that closes its first accounts on 31 December 2026 generally has YA 2027 as its first YA. Its actual first filing arrangements depend on its accounts and activities; check IRAS’s guidance for newly incorporated companies. Keep transaction records, prepare financial statements where required and review whether an annual general meeting can be dispensed with or is exempted.

Monitor GST under both tests. If calendar-year taxable turnover exceeds S$1 million, an application is generally due by 30 January of the following year. If turnover is reasonably expected to exceed S$1 million in the next 12 months, the application is generally due within 30 days of the forecast. Exceptions or exemptions may apply. CPF obligations also depend on who is employed and their status.

Practical Steps That Are Not Legally Required

A common seal is not compulsory. A company chop or self-ink stamp can still be useful if a counterparty requests one. A logo, website, commercial office and business plan are commercial decisions rather than standard incorporation filings. Separate licences, finance applications or contracts may impose additional requirements.

Licences and Sector Approvals

Check the actual activity before trading: registration does not replace a sector licence. Food, employment agency, financial, education and healthcare activities may require approvals from their respective regulators. Use the government’s GoBusiness licensing guidance and allow for any inspections or supporting documents.

What Support Schemes Are Available to New Companies in 2026?

Eligible companies may receive a YA 2026 tax rebate, a cash grant or both. Conditions and a combined cap apply.

IRAS administers several measures that may be relevant to businesses. Eligibility depends on the scheme and its qualifying period:

• The enhanced YA 2026 Corporate Income Tax rebate is 50% of tax payable. The rebate and any associated cash grant are capped at S$40,000 in total.
• An active company meeting the 2025 local employee condition receives a S$2,000 CIT Rebate Cash Grant. The grant is accounted for in the combined benefit; it is not an extra amount above the cap.
• The SME Cash Grant 2026 provides eligible companies S$500 per qualifying local employee, up to S$2,500. It uses the highest qualifying monthly headcount from April to June 2026. Other eligibility conditions apply, including timely CPF contributions.
• The Enterprise Innovation Scheme offers enhanced deductions or allowances for qualifying activities, subject to caps. Eligible businesses may instead convert qualifying expenditure into cash, subject to conditions.

For the Enterprise Innovation Scheme, eligible businesses can convert up to S$100,000 of qualifying expenditure at 20%, in place of deductions or allowances. The cash option has an employee condition and does not apply to the new AI adoption activity. That activity is available for YA 2027 and YA 2028.

A company incorporated late in 2026 should not assume it qualifies for a measure based on an earlier employee period. Check the relevant IRAS scheme page and the company's own circumstances before budgeting for support.

Conclusion

Choosing an entity, confirming an eligible director and preparing the filing documents can prevent delays. After registration, a compliance calendar helps founders distinguish recurring obligations from optional business decisions.
