Thailand Overstay — Fines, Bans, and What to Do

THE FINE: 500 THB PER DAY The standard overstay fine is 500 THB for each day you have overstayed, up to a maximum of 20,000 THB for a single overstay. If your overstay exceeds 40 days (20,000 THB maximum divided by 500 THB/day), the daily fine stops increasing — but the other consequences do not. Example: 10 days overstay = 5,000 THB fine. 40 days = 20,000 THB fine. 100 days = still 20,000 THB fine (cap reached), but a potential entry ban. WHEN THE FINE IS PAID The fine is paid at the point of departure — at the airport or land border when you leave Thailand. You pay at the Immigration counter before the departure stamp is applied. You cannot pay the fine in advance at an Immigration office in Bangkok and then leave later — it must be paid at the exit point. Exception: if you surrender yourself voluntarily at an Immigration office before departing, you can pay and arrange departure. This avoids airport arrest on departure day. ENTRY BANS — WHEN THEY APPLY 1–90 days overstay: typically results in a 1-year entry ban from Thailand. 91 days – 1 year overstay: typically results in a 3-year entry ban. 1–3 years overstay: typically results in a 5-year entry ban. Over 3 years overstay: typically results in a 10-year entry ban. Over 5 years overstay: reportedly results in lifetime ban in some cases. These are administrative guidelines — individual cases may vary at officer discretion. OVERSTAY DISCOVERED AT DEPARTURE AIRPORT If you overstayed and are discovered at the departure airport (Suvarnabhumi, Don Mueang, Phuket International, etc.): the Immigration officer at the departure counter will flag the overstay. You will be taken to the Immigration processing area, asked to pay the fine (500 THB/day up to the 20,000 THB cap), and your passport will be stamped with the overstay record. You will then be allowed to depart — you are not typically detained for short overstays. The entry ban (if applicable to your overstay duration) will be applied to your record. Your passport is not confiscated — the ban is recorded on the immigration system against your name and passport number. OVERSTAY BY ONE DAY A one-day overstay (you leave one day after your permission expires) results in: 500 THB fine, payable at departure. No entry ban for a single-day overstay. The overstay is recorded in your immigration history. This is the most common overstay scenario — people miscalculate their permission expiry date. The exit stamp says "overstay" and a 500 THB fee is collected. It is uncomfortable but not catastrophic. WHAT TO DO IF YOU HAVE OVERSTAYED SHORT OVERSTAY (days to a few weeks): depart Thailand and pay the fine at the exit point. Announce the overstay proactively to the Immigration officer — do not attempt to conceal it. LONGER OVERSTAY: consider surrendering yourself at the Immigration Bureau before your planned departure. This allows you to handle the paperwork in a more controlled environment than an airport departure queue. Visa Centre can advise on this process. DO NOT: attempt to exit via a minor border crossing to avoid detection. Thai Immigration databases are connected. Do not attempt to pay someone to clear your record — this is fraud and exposes you to arrest. HOW TO AVOID OVERSTAY The most common cause: misunderstanding the permission date. Your permission to stay expires on the date stamped in your passport — this is not the same as your visa expiry date. Check the stamp, not the visa. The date in the stamp is the latest date you must leave or have extended your stay. Set a reminder 2 weeks before your permission date. If you need more time, apply for an extension at the Immigration Bureau before the permission date, not after. General guidance only.
