Taiwan Company Registration & Legal Setup
Framework
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.
