Penalties for Working Without a Work Permit in Thailand
Legal consequences of working illegally in Thailand, including fines, imprisonment, deportation, and re-entry bans for foreigners.
Overview
Working in Thailand without a valid work permit is a criminal offence carrying heavy penalties including imprisonment and deportation. The Working of Aliens Act strictly regulates foreign employment, requiring both a valid Non-Immigrant B visa and a work permit. Digital nomads working remotely for overseas employers technically fall under this requirement, though enforcement varies.
Penalties Table

|---|---|---|---|---|
| Working without a work permit | Working of Aliens Act B.E. 2551 (2008), Section 51 | THB 5,000 – 100,000 | Up to 5 years | Deportation and re-entry ban after conviction |

Important Notes
A visa does NOT authorize you to work — a separate work permit is required.
Even volunteer work may require a work permit depending on the activity.
Digital nomads working remotely are technically in violation, though the DTV visa addresses this.
Work permits are employer-specific — you cannot freelance or work for another company.
Both the employee and the employer face penalties for illegal employment.
Conviction results in deportation and a re-entry ban of up to 5 years.
