IRON LAW: Entity Type Determines Everything Downstream
The choice between 行號 (sole proprietorship), 有限公司, and 股份有限公司
determines: liability exposure, tax treatment, fundraising ability, and
exit options. This decision is hard to reverse — choose based on your
3-5 year plan, not just today's simplicity.

Gotchas
- 統一編號 is your identity: The 8-digit 統編 is used for everything — tax filing, invoicing, contracts, bank accounts. Get it first, then set up everything else.
- Capital verification is a one-time check: CPA verifies capital at registration. After that, the money can be used for business operations. You don't need to keep it sitting in the bank.
- Foreign founders: Non-ROC nationals can register companies but need an ARC (居留證) or APRC, and there are additional MOEA investment approval requirements.
- Address matters: The registered address determines which tax office you deal with. Using a virtual office is legal but may trigger more scrutiny.
- This is educational guidance, not legal advice: Taiwan company law is complex. Consult a licensed accountant (會計師) or lawyer (律師) for specific situations.
