Thailand Overstay Fine: How Much You Pay and When You Get Banned
Updated Mon, 12 October 2026
Calculate your overstay fine and ban →If you stay in Thailand past the date stamped in your passport, you have overstayed. A short overstay is usually just a fine at the airport, but a long one, or being caught by police, can get you banned from Thailand for years.
How much is the overstay fine?
The fine is 500 THB for each day you overstay, up to a maximum of 20,000 THB. You reach the maximum after 40 days.
| Days overstayed | Fine |
|---|---|
| 1 day | 500 THB |
| 7 days | 3,500 THB |
| 14 days | 7,000 THB |
| 30 days | 15,000 THB |
| 40 days or more | 20,000 THB (maximum) |
The day you leave counts as an overstay day. If your stamp says 10 March and you fly out on 12 March, you have overstayed 2 days.
When do you get banned?
It depends on whether you leave on your own or are arrested.
If you surrender yourself at the airport or border when leaving:
| Overstay | Re-entry ban |
|---|---|
| 90 days or less | No ban |
| More than 90 days | 1 year |
| More than 1 year | 3 years |
| More than 3 years | 5 years |
| More than 5 years | 10 years |
If you are arrested for overstaying (for example at a police checkpoint or hotel check):
| Overstay | Re-entry ban |
|---|---|
| Up to 1 year | 5 years |
| More than 1 year | 10 years |
An arrest can also mean time in an immigration detention centre while your deportation is arranged, at your own cost.
What happens at the airport?
Go to immigration as normal. The officer will see the overstay, send you to a separate desk to pay the fine in cash (Thai baht), and record the overstay in your passport and the immigration system. Leave enough time before your flight, and carry enough baht.
Can I fix an overstay before leaving?
Sometimes. If you are still inside Thailand, an immigration office may let you apply for an extension or a new visa and pay the overstay fine at the same time. This is at the officer’s discretion, so go as early as possible and bring proof of why you need to stay.
Tips to avoid problems
- Check the date in your latest entry stamp, not your visa sticker. The stamp is what counts.
- Set a reminder a week before your permitted stay ends.
- If you are sick or stuck, contact your local immigration office before the date passes, not after.
