Penalties for overstaying in Thailand
According to Ministry of Interior’s Order 1/2558 Regarding Classes of Aliens Ineligible for Admission to the Kingdom of Thailand
When entering the Kingdom of Thailand, please be mindful of the last day on your stay permit and DO NOT stay longer than the permitted date.
If you overstay for up to 90 days, you must pay a fine of 500 Baht per day, but not exceeding 20,000 Baht, before you are allowed to leave the Kingdom of Thailand.
