Foreign Business Act (FBA) Thailand
The Foreign Business Act restricts foreign participation in many Thai industries unless you obtain a licence, BOI promotion, or treaty protection. At Thai Visa Centre in Bangkok, we help foreign directors and employees navigate visas and work permits once your corporate team resolves FBA compliance.
Owning 49% of a Thai company does not automatically legalise a restricted activity. The Foreign Business Act looks at control and activity type, not share count alone. Compare alternatives in our BOI and Treaty of Amity guides.
Foreign Business Act B.E. 2542 (1999) governs foreign business participation.
Many licence categories require at least 3 million THB remitted per activity.
Foreign-majority Thai companies are treated as foreign under FBA.
Standard ratio of 4 Thai employees per 1 foreign work permit.
What is the Foreign Business Act?
The Foreign Business Act B.E. 2542 (1999) defines which business activities foreigners may conduct in Thailand and under what conditions. A foreigner includes foreign individuals, foreign companies, and Thai companies with majority foreign shareholding.
| List | Treatment |
|---|---|
| List 1 | Reserved for Thai nationals. Foreigners generally prohibited. |
| List 2 | Restricted. Foreign participation needs Cabinet approval plus licence. |
| List 3 | Restricted. Foreign participation needs Ministry of Commerce licence. |
Examples of List 3 activities (not exhaustive): retail under certain thresholds, legal services except international arbitration, construction, brokerage, and many service businesses.
When do you need an FBA licence?
| Trigger | Detail |
|---|---|
| Foreign-majority limited company | Conducting List 2 or List 3 activity |
| Branch office | Performing restricted activities in Thailand |
| Foreign control despite Thai majority | Nominee structures are illegal and may still trigger FBA scrutiny |

BOI promotion
Permitted promoted activities may exempt from FBA for that activity
US Treaty of Amity
US majority in non-excepted sectors
Thai majority with genuine control

Capital and ownership rules
| Structure | FBA trigger |
|---|---|
| 50%+ foreign shares | Foreign company under FBA |
| <50% foreign with foreign control | Still treated as foreign |
| Thai majority, genuine control | Many activities exempt from licence |
| Branch of foreign company | Always foreign |
FBA and immigration: FBA compliance affects company legitimacy for work permits, not visa category directly. Foreign employees still need a non-immigrant B visa and work permit. See work permit guide.
Common mistakes
- Nominee Thai shareholders to circumvent FBA. Criminal penalties apply.
- Starting revenue operations before licence approval
- MOA objectives too broad with licence scope mismatch
- Assuming BOI or Amity without formal certificate in hand
- 49% foreign structure with foreign managing director controlling all decisions
