Can registrations with social security be backdated in Taiwan?

No, registrations with social security in Taiwan cannot be backdated. Under Taiwan’s labor laws, employees must be registered with both Labor Insurance and National Health Insurance (NHI) on their official start date. Employers are legally required to complete this registration process on or before the employee’s first day of work.

Key Points:

  • Same-Day Registration Required: The employee's enrollment in labor and health insurance must begin on the actual employment start date stated in the contract.

  • No Retroactive Registration: Backdating social security registration is not permitted under Taiwan's legal framework. Late registration can result in penalties for the employer and a gap in insurance coverage for the employee.

  • Employer Obligation: Horizons ensures that all employee registrations are submitted in compliance with national requirements to avoid legal and coverage issues.
