Complete Guide to Establishing a Single-Person Company: A Professional Handbook on Financial and Tax Strategies

With the recent rise of micro-entrepreneurship, freelancers, and digital nomads, a “single-person company” (referring to a limited company or corporation with only a single shareholder) has become the top choice for many entrepreneurs. However, transitioning from “individual contracting” to an “incorporated entity” is much more than just adopting a business name—it involves completely different financial architectures and tax planning strategies.

As a practicing Certified Public Accountant (CPA), this article will guide you through the core essentials and potential pitfalls of setting up a single-person company from a professional financial and tax perspective.

1. Why Form a “Single-Person Company”? (Organizational Form Evaluation)

In Taiwan, a single-person company typically chooses between a “Limited Company” (most common, with relatively low maintenance costs) and a “Corporation/Company Limited by Shares”. Compared to sole proprietorships or partnerships (firm entities), corporate entities offer distinct advantages:

Limited Liability: Shareholders are liable only to the extent of their capital contribution, effectively isolating personal assets from business operational risks.
Brand Trust: Corporate clients signing contracts, making purchases, or outsourcing projects typically prefer collaborating with a “company” holding a Uniform Business Number.
Scalability Ceiling: Not constrained by the NT$200,000 monthly revenue limit of small-scale businesses, providing greater flexibility in issuing invoices and scaling operations.

2. Financial Perspective: Separating Personal and Business Accounts & Capital Planning

One of the most common pitfalls for novice business owners is treating “company money” as “personal pocket money.” Financially, a single-person company must establish strict discipline:

1. Complete Separation of Personal and Business Accounts

Once the company is established, you must open a corporate preparatory account and an official corporate bank account under the company’s name. All business revenues must go directly into the corporate account, and business expenses must be paid from it. If an owner frequently withdraws cash from the company without legitimate vouchers or loan records, the National Taxation Bureau may treat it as “shareholder misappropriation of funds,” which can lead to back taxes or, in severe cases, suspicions of breach of trust or tax evasion.

2. How Much Capital Should Be Set?

Although Taiwan’s Company Act now adopts a “paid-in capital system” with no statutory minimum capital requirement upon establishment (no longer mandatorily requiring NT$2 million or NT$5 million), CPAs recommend planning capital based on “estimated operational costs and overhead expenses for the first three months”:

Excessively low capital (e.g., a few thousand dollars): The company may face cash flow strains shortly after inception and find it harder to secure bank loans or government grants.
Excessively high capital: While visually appealing, if idle funds are too high, reducing capital later requires specific statutory procedures.

💡 CPA Practical Recommendation: Once injected, capital can be used to pay rent, software subscriptions, salaries, or initial equipment. Remember to retain all receipts and invoices (such as triple-part uniform invoices and contracts), as these serve as essential documentation for the company to book expenses and recognize costs.

3. Tax Perspective: Corporate Income Tax, Individual Income Tax, and Earnings Distribution

Tax planning is the core challenge of a single-person company. Entrepreneurs must understand the interconnected dynamics of three major tax burdens:

Tax Type	Tax Rate / Calculation Method	CPA Analysis & Tax-Saving Focus
Profit-Seeking Enterprise Income Tax (Business Income Tax)	Standard rate is 20%; taxable income up to NT$120,000 is exempt; income between NT$120,000 and NT$500,000 enjoys preferential rates (historically structured as tiered brackets or 15%–20% preferences).	Net profits earned by the company are subject to business income tax first. Rationally recognizing costs and expenses (e.g., office expenses, labor/health insurance, depreciation) is key to lowering business income tax.
Owner’s Salary & Labor/Health Insurance	The owner can draw a salary by “acting as an employee of the company,” which can be listed as a corporate expense (expensed).	While salaries reduce corporate surplus (lowering business income tax), they become the owner’s personal “salary income” and must be factored into individual comprehensive income tax. Calculations are needed to find the optimal balance.
Earnings Distribution / Dividend Income	Post-tax earnings after corporate income tax, if distributed to you as the sole shareholder, must be included in individual comprehensive income tax, or subjected to a “separate taxation rate of 28%” or “consolidated taxation with an 8.5% tax credit deduction.”	This is a stage of double taxation (business tax paid first, followed by individual income/dividend tax). Properly planning the ratio of salary to dividends is core to optimizing personal tax burdens.

⚠️ Avoiding Common Tax Pitfalls: Although a single-person company consists of just you, the “company” and “you personally” are two legally distinct entities. You cannot casually take company funds to pay personal mortgages or buy personal private goods without proper accounting records. All major expenditures must have legitimate documentation; otherwise, expenses will be disallowed during annual closing, potentially triggering back taxes and penalty fines.

4. Four Golden Steps to Establish a Single-Person Company

Company Name Reservation: Apply for a company name pre-check with the Department of Commerce, Ministry of Economic Affairs (recommended to prepare 3–5 backup names).
CPA Capital Audit and Certification: Deposit the capital into the preparatory account and have a CPA conduct a capital audit and issue a certification report.
Complete Company Registration: Apply for incorporation registration with local governments (special municipality/county/city governments) or the Central Region Office of the Ministry of Economic Affairs.
National Taxation Bureau Tax Registration & Invoice Purchase: Upon obtaining the Uniform Business Number, complete tax registration with the National Taxation Bureau and apply to purchase uniform invoices (or e-invoices) based on business needs.

Conclusion

Setting up a single-person company sounds straightforward, but financial and tax compliance directly impacts future corporate credit and your personal wallet. Properly executing the separation of personal and business accounts, prudently planning capital, and running tax simulations for salaries and earnings with a CPA’s assistance will allow your single-person company to maximize its business potential on a compliant and robust foundation!
