Verified 1 August 2026. Overstay is measured against the “admitted until” date in the passport or electronic immigration record, not the visa sticker’s validity date. A re-entry permit preserves an existing permission to stay when its holder travels; it does not extend an expired permission.

What the official fine schedule says

As of 1 August 2026, the Immigration Bureau’s official bilingual handbook states an overstay fine of THB 500 for each day, capped at THB 20,000. The same handbook says the fine for a one-day overstay may be waived. That is a possible waiver, not an extra day added to the permission to stay and not something a traveller can assume in advance.

The handbook also states that children under 15 years are not fined. It does not say that this removes the child’s immigration-status record or every other possible consequence; Immigration is the authority for case-specific confirmation.

The handbook says payment is made in Thai baht and warns that a person unable to pay may be prosecuted. It does not publish a guaranteed detention timetable or a standard arrangement for instalments. Source: Immigration Bureau official bilingual handbook (checked 1 August 2026).

Entry-ban periods depend on how the case is detected

Thailand’s official overstay measures have applied since 20 March 2016. They distinguish a person who reports and leaves voluntarily from a person who is arrested and prosecuted. The thresholds below reproduce the official schedule; “more than” matters at each boundary.

Official categoryRecorded overstayOfficial re-entry ban
Voluntary surrenderMore than 90 days1 year from departure
Voluntary surrenderMore than 1 year3 years from departure
Voluntary surrenderMore than 3 years5 years from departure
Voluntary surrenderMore than 5 years10 years from departure
Arrested and prosecutedLess than 1 year5 years from departure
Arrested and prosecutedMore than 1 year10 years from departure

As of 1 August 2026, those periods remain published by the Royal Thai Embassy in Abu Dhabi and in current bilingual Immigration acknowledgement forms. The official voluntary-surrender schedule does not list a re-entry-ban tier for an overstay of 90 days or less. That does not promise future admission: a visa and entry remain subject to the responsible authorities’ decisions.

The official schedule does not support claims that every person found overstaying receives the same “automatic criminal record,” or that every case follows a fixed detention or court timeline. Arrested cases can involve detention, prosecution and deportation, but the facts and process are case-specific.

Temporary 2026 relief was limited to affected travellers

On 4 March 2026, Thai authorities announced temporary relief for foreign travellers unable to depart because of Middle East airspace closures. The official notice covers affected permissions expiring from 28 February 2026: qualifying departing travellers could have overstay fines waived, while qualifying people remaining in Thailand could request an extension of up to 30 days with the documents named in the notice.

This was not a general overstay amnesty. The notice says the measures remain until the situation returns to normal or the authorities revoke them. As of 1 August 2026 no later official revocation notice was found, but only Immigration can confirm whether a particular traveller and date remain within it. See the Government Public Relations Department notice (4 March 2026, re-opened 1 August 2026) and the Tourism Authority of Thailand notice relaying the Immigration Bureau measures.

What the published rules do not establish

How to get an authoritative case answer

Overstay consequences turn on the exact admitted-until date, whether the person was arrested, and any official relief or court process that applies. For confirmation, use the Immigration Bureau contact named in the 4 March 2026 notice—hotline 1178, as published on that date—or the immigration office handling the case. A traveller outside Thailand can also contact the Royal Thai Embassy or Consulate responsible for the intended application.

For a case involving arrest, detention, a child, illness or inability to travel, the public rules may not answer every fact. The responsible Immigration office, the person’s embassy and an independently chosen qualified Thai lawyer are the appropriate sources for case-specific assistance. This page reports the published rules and does not predict an individual outcome.

Frequently asked questions

Is there a one-day grace period?

No extra day is added to the immigration permission. As of 1 August 2026, the official Immigration handbook says a one-day overstay fine may be waived. “May” is not a guarantee.

Does paying the fine reset a visa or permission to stay?

No. The fine and the immigration permission are separate. The official sources checked on 1 August 2026 do not say that payment renews or extends status.

Does voluntary departure always avoid a ban?

No. Under the official schedule effective 20 March 2016, voluntary surrender after more than 90 days triggers the first published ban tier. Shorter cases can still be recorded and future entry remains discretionary.

Does being arrested produce the same ban as voluntary surrender?

No. The official schedule is substantially stricter for a person arrested and prosecuted: less than one year of overstay carries a five-year ban, and more than one year carries a ten-year ban, measured from departure.

Are children exempt from every overstay consequence?

The Immigration Bureau’s bilingual handbook, as last re-confirmed on 1 August 2026, says children under 15 are not fined; its hosting page could not be re-opened on 1 August 2026, so treat this as the last-confirmed position. It does not publish a blanket exemption from every status, travel or record consequence.

Can an old overstay affect a future visa or entry decision?

The sources do not promise approval after a fine is paid or a ban expires. The visa-issuing post and Immigration decide applications and admission under the rules and facts then in force.
