Thailand fines overstays at ฿500 a day, capped at ฿20,000 — but the real cost is the re-entry ban that kicks in past 90 days. Enter your permitted-to-stay date and exit date to see the exact fine and the ban tier you’d fall into. Information only, no paid placement.
Enter the permitted-to-stay date from your latest entry stamp (not the visa validity date) and the date you plan to leave. We’ll count the overstay days, the cash fine, and flag the re-entry ban tier. Information only — nothing here is legal advice.
The overstay clock runs from your permitted-to-stay date — the handwritten or stamped date in your passport from your last entry — not the date your visa was issued or expires. Find that stamp, enter it above, and the fine and ban tier appear instantly.
Overstaying a Thai visa is fined ฿500 for each day past your permitted-to-stay date, capped at ฿20,000 — so the fine maxes out at 40 days and never rises further. It’s paid in cash baht, usually to Immigration as you leave. The bigger risk is the re-entry ban: leaving voluntarily, 90 days or less is normally the fine with no ban; over 90 days triggers a 1-year ban; over 1 year, 3 years; over 3 years, 5 years; over 5 years, 10 years. If you’re arrested inland rather than leaving on your own, it’s harsher — a 5-year ban under 1 year of overstay, 10 years over that, plus possible detention. The fix is simple: watch the stamp and extend before it expires rather than relying on the fine.
Information and a date-based estimating tool only — not legal or immigration advice. Penalty and ban rules can change and are applied at the discretion of Thai Immigration; the permitted-to-stay date on your stamp governs, not visa validity. Always confirm current rules with Thai Immigration or a qualified adviser before acting. BAANLYY never takes paid placement.
The single most common cause of an accidental overstay is watching the wrong date. Your visa has an issue date and an expiry date, but the clock that matters is the permitted-to-stay date — the date Immigration stamps or writes in your passport each time you enter. A one-year visa can still only grant, say, 60 or 90 days per entry. Find the stamp from your most recent arrival, enter it above, and you’ll see exactly where you stand on any date you choose.
The cash side is simple and forgiving: ฿500 per day, capped at ฿20,000, which you hit at 40 days. After that the fine never grows. That can lull people into thinking a long overstay is no worse than a short one — but the re-entry ban tells a different story. Past 90 days you’re looking at a 1-year ban; past a year, three years; and it climbs from there. The fine is a rounding error next to being locked out of the country for years, so the day count above matters far more than the baht figure.
How your overstay ends changes the penalty. If you surrender voluntarily by leaving on your own, the ban tiers are the standard ones: nothing under 90 days, then 1, 3, 5 and 10 years as the overstay lengthens. If you’re arrested inland — at a checkpoint, during a reporting visit, or a random check — it’s harsher: a 5-year ban under a year of overstay, 10 years above that, plus possible detention at an Immigration Detention Centre. The lesson is to leave or regularise on your own terms, before someone else makes the decision for you.
It doesn’t file anything, contact Immigration, or guarantee an outcome — penalties and bans are applied at the discretion of Thai Immigration and rules change. It assumes a single continuous overstay from the date you enter, counted to your chosen exit date. Treat the result as a clear picture of the standard fine and ban tiers so you can plan an extension or a border run in good time — then confirm the current rules with Immigration or a qualified adviser before you act.
Now plan the visa route that keeps you legal for the long haul, and where to actually live.
