Limitations

Permanent Residency (PR)

Thai Citizenship

Land Ownership

• Foreign spouses may not legally own land, even if married to a Thai

• Thai spouse can own land, but the foreigner must sign a declaration confirming:

  • They did not fund the purchase

  • This is to comply with the Thai Land Code restricting indirect foreign ownership

Building Ownership

Joint Ownership with Thai Spouse

• Thai spouse may own ≥51% of a Thai limited company

• Foreign spouse may own up to 49%, unless in a restricted sector

Considerations

Personal Income Tax

• Marriage does not alter tax residency status

• If the foreign spouse stays ≥180 days per year in Thailand:

  • They are considered a Thai tax resident

  • Residents are taxed on worldwide income

  • Non-residents are taxed on Thailand-sourced income only
