How to Start a Business in Singapore from the US: A Step-by-Step Guide for 2025

American entrepreneurs and business owners increasingly look at Singapore as a serious operational base for reaching Asian markets. The country’s legal framework is straightforward, its tax structure is competitive, and its position between major trade corridors makes it a practical choice for companies that need a stable regional headquarters. But setting up a business from the United States involves more moving parts than most people anticipate. Time zone differences, unfamiliar regulatory processes, and the need to coordinate across multiple agencies can slow down even a well-funded expansion if the groundwork isn’t laid correctly.

This guide walks through the actual process — what’s required, what decisions must be made early, and where most foreign founders encounter delays or complications they weren’t expecting.

Understanding What Business Setup in Singapore Actually Requires

Business setup in Singapore is governed primarily by the Accounting and Corporate Regulatory Authority (ACRA), which is the national regulator and administrator of business entities in the country. Foreign nationals can own a company outright in Singapore — there is no mandatory local ownership requirement for most business structures. However, certain operational requirements do apply specifically to companies incorporated by non-residents, and understanding these requirements before beginning the registration process saves significant time and money.

For US-based founders, a detailed walkthrough of the procedural and structural requirements involved in business setup in Singapore is essential reading before making any commitments. The process is more accessible than many assume, but it is not self-service in the way that US-based LLC formation often is.

The Requirement for a Locally Resident Director

Every private limited company incorporated in Singapore must have at least one director who is ordinarily resident in Singapore. This means a Singapore citizen, a permanent resident, or someone holding an EntrePass or Employment Pass. This is not a formality — the resident director has real legal accountability under the Companies Act and cannot simply be a placeholder name.

For US founders who will not be relocating, this requirement typically means engaging a nominee director service. These are professional individuals or services that fulfill the legal residency requirement while the actual business decisions remain with the founders. The nominee director arrangement must be formally documented, and any reputable provider will require a director’s service agreement that clearly outlines limitations and responsibilities. Rushing this step or choosing an unvetted provider creates downstream liability risk.

Choosing the Right Business Structure

The private limited company — locally referred to as a Pte Ltd — is the most common structure for foreign-owned businesses in Singapore. It offers limited liability protection, is eligible for startup tax exemptions, and is recognized as a credible business entity by local banks and partners. Other structures exist, including sole proprietorships and limited liability partnerships, but these are generally not suitable for US founders operating remotely because they either require Singapore citizenship or offer fewer legal protections.

A branch office is another option, which allows a foreign company to operate as an extension of its parent entity rather than as a separate legal entity. This can simplify certain internal accounting arrangements but also means the parent company carries full liability for the branch’s activities in Singapore. For most US companies testing the Singapore market, a separate Pte Ltd offers better risk containment.

The Registration Process Through ACRA

Singapore’s business registration system operates through a digital platform called BizFile+, administered by ACRA. The registration process itself is not lengthy — in straightforward cases, incorporation can be completed within one to two business days once all documents are submitted and the application is approved. The preparation stage, however, typically takes longer, especially for foreign applicants who need to gather and authenticate documents from overseas.

Documents Required for Foreign Founders

US founders will need to provide proof of identity, a residential address outside Singapore, and details of the proposed company including its name, registered address in Singapore, business activity descriptions using the Singapore Standard Industrial Classification codes, and initial share structure. All foreign-identity documents typically need to be certified copies, and some registrars may require notarization depending on the nature of the application.

A registered office address in Singapore is also mandatory from the point of incorporation. This must be a physical address — not a PO box — and it must be a place where official correspondence and government notices can be received. Many business setup service providers include a registered address as part of their incorporation package, which is a practical option for founders who don’t yet have a physical office.

Selecting Your Business Activity Codes

Singapore uses a structured classification system to categorize what a business does. When registering, you must select the SSIC codes that most accurately describe your primary and secondary business activities. These codes influence how your business is categorized for licensing purposes, government reporting, and in some cases, eligibility for sector-specific grants or regulations.

Selecting inaccurate or overly broad codes is a common mistake among first-time registrants. Some business activities in Singapore require additional licenses beyond ACRA registration — financial services, education, food and beverage, healthcare, and employment agencies are examples where sector-specific regulatory approval is required before operations can begin. Choosing the wrong code and missing a licensing requirement can result in operating in breach of Singapore law, even unintentionally.

Opening a Corporate Bank Account as a Foreign Owner

Bank account opening is one of the most consistently reported difficulties for US-based founders registering a Singapore company. Singapore’s major banks — including DBS, OCBC, and UOB — have tightened their due diligence requirements for foreign-owned entities significantly over the past several years. Expect a thorough review of your business model, source of funds, identity documentation, and in many cases, an in-person meeting requirement.

Why Remote Account Opening Is Difficult

Most traditional Singapore banks require at least one director or authorized signatory to appear in person at a branch to complete the account opening process. For US founders who are not relocating, this means either traveling to Singapore specifically for the purpose or working through a service that can facilitate the process through authorized channels.

Digital business banks and fintech platforms — such as Airwallex, Wise Business, and certain neobanks licensed in Singapore — offer more flexible account opening processes that can often be completed remotely. These platforms may not offer the full suite of services that a traditional bank provides, but they can serve as a functional starting point for receiving payments, paying local vendors, and managing operational cash flow while the traditional bank application progresses.

Documentation Banks Will Request

Beyond the company’s incorporation certificate and business profile from ACRA, banks typically require a description of the business model, expected transaction volumes and types, supplier and customer information, proof of contracts or revenue, and personal identification for all directors and significant shareholders. Incomplete submissions slow the process considerably. Preparing a clear and accurate business overview document in advance — one that explains the business in plain language alongside the documentation — tends to produce faster responses from relationship managers.

Tax Obligations and Ongoing Compliance

Singapore’s corporate tax framework is governed by the Inland Revenue Authority of Singapore. The headline corporate tax rate is competitive by international standards, and newly incorporated companies are eligible for a startup tax exemption scheme that reduces effective tax on initial years of chargeable income. This makes the first few years of operation in Singapore relatively tax-efficient for early-stage businesses.

According to the Inland Revenue Authority of Singapore, new companies that meet the qualifying conditions can receive substantial tax exemptions on the first portion of their chargeable income for each of their first three consecutive years of assessment, subject to conditions around the nature of ownership and income sources.

Annual Filing Requirements

Singapore companies are required to hold an Annual General Meeting and file annual returns with ACRA. They must also file corporate income tax returns with IRAS. If the company’s annual revenue exceeds a defined threshold, it is required to register for Goods and Services Tax (GST), which is Singapore’s equivalent of value-added tax. Missing these filings results in penalties and, in persistent cases, can lead to enforcement action against the company and its directors.

For US founders managing a Singapore entity remotely, engaging a local corporate secretary is not optional — it is a legal requirement. Singapore law mandates that every company appoint a qualified company secretary within six months of incorporation. This person is responsible for maintaining statutory records, ensuring filing deadlines are met, and advising the board on compliance matters under Singapore law.

Common Delays and How to Avoid Them

Most delays in the Singapore incorporation process for US founders stem from three areas: incomplete or non-compliant documentation, failure to identify licensing requirements early, and underestimating the time needed to open a bank account. These are all solvable problems, but they require attention before the application is filed rather than after.

Engaging an incorporation service or legal firm that specializes in foreign-owned companies gives you access to a structured checklist, ensures that your documents meet ACRA’s current requirements, and provides guidance on whether your business activity requires a license. It also gives you someone local who can respond to queries from ACRA, banks, or other agencies on your behalf during business hours in Singapore — which, given the time difference with the US East Coast, is practically significant.

Conclusion

Starting a business in Singapore from the United States is entirely achievable, and for the right type of business, it is one of the more straightforward international expansions available to American founders. The regulatory environment is stable, the rules are clearly written, and the government has invested meaningfully in making the process accessible to foreign entrepreneurs.

What it is not, however, is fully self-service. The resident director requirement, the bank account process, ongoing compliance obligations, and sector-specific licensing all require local knowledge and local relationships. Business setup in Singapore works best when treated as a structured project with defined milestones — incorporation, banking, licensing, compliance calendar — rather than a one-time administrative task. Founders who approach it that way tend to get operational faster and with fewer complications in the months that follow.

The process rewards preparation. If you have a clear business model, organized documentation, and the right local partners in place before you begin, the path from US-based idea to Singapore-incorporated company is more manageable than most people expect going in.
