Key takeaways
- Paying an overstay fine does not renew your permission to stay or cancel a removal order.
- Voluntary surrender and arrest have different re-entry ban thresholds.
- Immigration detention and release on bail in a criminal case are separate matters.
- Section 54 allows conditional residence pending removal, subject to official approval; release is not automatic.
What does paying the THB 20,000 overstay fine actually resolve?
Section 81 of Thailand’s Immigration Act B.E. 2522 (1979) covers staying without permission, after permission has expired, or after it has been revoked. The statutory maximum is two years’ imprisonment, a THB 20,000 fine, or both. The offence is therefore not necessarily a fine-only matter. Source: OCS: Immigration Act, Section 81.
The familiar rate of THB 500 per day, capped at THB 20,000, appears in official guidance on overstay fines. It is not the full penalty provision in Section 81 and should not be presented as the inevitable outcome of every prosecution. See the Thai government’s overstay-fine guidance.
Under Section 84, payment of a fine under a lawful settlement ends the criminal case covered by that settlement. That does not grant further permission to remain. If the case instead results in a court judgment, all applicable parts of that judgment must be addressed. Source: OCS: Immigration Act, Section 84.
Can Thailand still deport you after the fine is paid?
Yes. Section 54 separately authorises removal of a foreign national who entered or remains without permission, or whose permission has expired or been revoked. Payment of a criminal fine does not remove that separate immigration power. A fine receipt is not an extension of stay or a guarantee of immediate release. Source: OCS: Immigration Act, Section 54.
In this article, “deportation” refers to immigration removal under Section 54. Your criminal case, immigration status and any restriction on returning to Thailand must each be checked.
How do the re-entry bans differ between surrender and arrest?
Minister of Interior Order No. 1/2558 sets different periods for people who surrender and people who are arrested and prosecuted. The ban runs from the date of departure from Thailand. The order took effect on 20 March 2016.
| Situation | Overstay period | Re-entry ban |
|---|---|---|
| Voluntary surrender | More than 90 days, up to and including 1 year | 1 year |
| Voluntary surrender | More than 1 year, up to and including 3 years | 3 years |
| Voluntary surrender | More than 3 years, up to and including 5 years | 5 years |
| Voluntary surrender | More than 5 years | 10 years |
| Arrest and prosecution | Up to and including 1 year | 5 years |
| Arrest and prosecution | More than 1 year | 10 years |
The exact one-year boundary matters: the original Thai text places an arrested person’s overstay of not more than one year in the five-year band. The ten-year band applies when the overstay exceeds one year.
For surrender with an overstay of 90 days or less, this order does not impose the above overstay ban. That is not immunity from the offence or a guarantee of admission on the next visit. The order also excludes people who depart before their eighteenth birthday, as well as departures before the order took effect.

Does every arrested person have to enter the Suan Phlu IDC?
A criminal case and immigration-removal proceedings may follow one another. However, it is inaccurate to describe every case as an identical sequence of a district-court hearing followed by detention at Suan Phlu. The relevant procedure, location and orders need to be checked individually.
Section 54, paragraph three, allows an officer to permit residence at a designated place pending removal, with reporting obligations and, where required, a guarantee or security. Alternatively, the officer may detain the person as necessary for removal. Conditional residence requires approval; it is not an automatic entitlement. Source: OCS: Immigration Act, Section 54.
Release on bail in a criminal case does not, by itself, resolve separate immigration custody. Equally, the existence of detention powers does not justify assuming that there is no possible request for an alternative arrangement.
Who pays the detention and removal costs?
The Act distinguishes detention expenses from removal expenses. Section 54, paragraph three, assigns the expenses of detention under that paragraph to the foreign national. Section 55 separately addresses removal costs, including responsibility of the owner or controller of the vehicle that brought the person into Thailand and, where that person is not apparent, an offender under Section 63 or 64. It also allows an officer to approve a different vehicle or route requested and funded by the foreign national.
It is therefore too broad to say that every foreign national must personally pay every airfare, medical and escort charge in every case. The legal basis and arrangements should be checked. Travel documents and funding may affect the timetable, but lack of money should not be described as automatically eliminating every possibility of seeking an alternative to detention. Source: OCS: Immigration Act, Sections 54–55.
What should you do if you discover an overstay?
- Check your permission-to-stay date. Review entry stamps and extension records, not just the validity dates printed on a visa.
- Gather the documents. Keep your passport, application records, relevant orders and evidence of any circumstances that prevented departure.
- Obtain advice promptly about lawful contact with the authorities and departure. A long overstay, another pending case or missing travel documents may require additional preparation.
- Keep the official records. Preserve fine receipts, orders and proof of departure to establish what happened and when.
An intention to surrender later does not protect you from arrest beforehand. Reaching the THB 20,000 fine cap is not a reason to delay resolving your status.
Frequently asked questions
Can I stay in Thailand after paying the maximum overstay fine?
No permission to stay is created by paying the fine. You need a separate lawful basis to remain, and immigration removal may still follow.
Is an overstay of less than 90 days safe from a re-entry ban?
Not in every situation. The order distinguishes voluntary surrender from arrest and prosecution. The arrest rules have different thresholds, and other admission restrictions may also matter.
Does buying a flight ticket guarantee immediate release?
No. The criminal case, immigration orders, travel arrangements and required official approvals still need to be checked.
Can I ask to live outside immigration detention while awaiting removal?
Section 54 permits conditional residence pending removal, but the arrangement requires official approval. It is separate from criminal bail and is not guaranteed.
Can I definitely return once my re-entry ban ends?
No. You must still satisfy the visa and admission requirements applicable when you travel. Expiry of a particular ban does not guarantee entry.
