1. One-Off Setup Costs: How Much Does Incorporation Registration Cost?
The first step in solo entrepreneurship is registering a commercial entity or company. Outflows during this phase are primarily one-time fees:
- Official Government Fees & Company Seals: Name reservation fee (NT$ 150) + company registration fee (NT$ 1,000 for capital under 4 million) + official company and director seal carving (approx. NT$ 300 – 800), totaling approx. NT$ 1,500 – 2,000.
- CPA Capital Audit Certification Fee: Under the Company Act, limited companies or companies limited by shares must have a licensed CPA issue a capital audit certification report, costing approx. NT$ 3,000 – 5,000.
- Agency Incorporation Service Fee: Engaging a professional CPA firm to handle name reservation, document drafting, articles of incorporation, and tax registration with the National Taxation Bureau typically incurs a service fee of NT$ 4,800 – 8,800.
2. Registered Business Address Costs: Home Address vs. Business Center Address Rental
Most solo entrepreneurs do not require physical storefronts, so address selection directly impacts monthly fixed overhead:
🏢 Comparison of 2 Common Business Address Options:
• Option A: Personal Home Address Registration (Lowest Out-of-Pocket Cost)
If the property is owned by yourself or direct relatives, you can apply to register at home. The advantage is saving on rent, but the drawback is that the house tax for that portion of floor area increases to the commercial rate (from 1.2% up to 3%+), and land value tax rates will also be affected.
• Option B: Business Center / Virtual Office Address Rental (Most Recommended)
If your rental residence cannot be registered, renting a business center address is the most popular solution. Market rates run around NT$ 1,500 – 3,000 / month (approx. NT$ 18,000 – 36,000 per year), with the added benefits of mail handling and a reputable commercial address.
3. Bookkeeping and Tax Costs: Does a Solo Company Need a CPA?
Once a company is formed, tax filings with the National Taxation Bureau are mandatory on a regular schedule regardless of whether revenue was generated that month. A solo founder’s time is valuable; trying to self-navigate commercial accounting laws and government tax filing systems often leads to costly errors.
- Outsourced Bookkeeping Retainer Fee: For standard invoice-issuing solo companies or sole proprietorships, CPA monthly bookkeeping fees run approx. NT$ 2,000 – 2,500 / month.
- Industry Billing Practice (14 Months/Year): Accounting industry standards bill for 14 months per year (12 monthly retainer fees + 1 month for annual corporate income tax settlement filing + 1 month for annual income withholding statements and closing), bringing total annual bookkeeping costs to approx. NT$ 28,000 – 35,000.
- Basic Tax Estimates:
• Business Tax (VAT): Filed bimonthly at a 5% rate (Tax Payable = Output Tax – Input Tax).
• Corporate Income Tax (CIT): Filed every May, calculated at a 20% tax rate based on net taxable profit or standard audit profit rates.
