Thailand still runs one of the more open tourist-entry systems in Southeast Asia. For UK visitors in August 2026 the practical picture is: 60-day visa exemption stamp, TDAC filed online, passport with six months validity. A Cabinet decision on 19 May 2026 approved rolling most exemptions back to 30 days. That rollback had not been gazetted as of this verification — so the border was still stamping 60. Check GOV.UK and the Royal Thai Embassy in London in the week you fly, not a Facebook group from 2024.
The paper TM.6 arrival card is gone. TDAC replaced it.
UK citizens — visa exemption (what was stamping in August 2026)
UK passport holders do not need a visa for ordinary tourist visits under the exemption scheme. You present the passport, the TDAC QR, and you get a stamp. It is an exemption, not a visa-on-arrival you pay for at the desk.
| Pin (August 2026) | What it means |
|---|---|
| 60-day exemption | Still being stamped for UK passports as of this verification |
| 30-day rollback | Cabinet-approved 19 May 2026; not gazetted then — not yet law |
| TDAC | Mandatory digital arrival card at tdac.immigration.go.th — free; third-party sites that charge are scams |
| When to file TDAC | Within 72 hours before arrival (air, land, sea) |
| Passport | Valid at least 6 months from arrival; a blank page for the stamp |
| Onward ticket | Still a rule. Rarely asked at airports; more often at land borders and by some airlines at check-in |
| Proof of funds | Officers may ask for evidence on the order of 20,000 THB per person (40,000 per family). Seldom at BKK; more likely at a land booth |
| Extension | +30 days at Immigration, commonly ฿1,900 — verify at the office |
TDAC, not TM.6
Since 1 May 2025 every foreign arrival files the Thailand Digital Arrival Card on the government site. It is not a visa. It does not replace the exemption or a TR visa. Complete it within 72 hours of arrival. Screenshot the QR. If the name does not match the passport exactly, automated gates will not love you.
A RFID passport holder is for the document. The QR lives on the phone; a screenshot lives where the phone can die.
Extension
The 60-day exemption can be extended by 30 days (total 90) at a Thai Immigration office. Cost commonly ฿1,900. Typical papers: passport, TDAC/arrival record, one passport photo, completed TM.7. Budget 1–3 hours. Dress like a person, not a beach.
Offices visitors actually use:
- Bangkok: Immigration Bureau, Government Complex, Chaeng Wattana Road
- Chiang Mai: Promenada Mall, 3rd floor
- Phuket: Phuket Town, Phuket Road
- Ko Samui: near Nathon
Hours move on public holidays and wan phra substitution days. Thai calendar.
Other nationalities (exemption is not one number forever)
| Nationality | Arrangement (check embassy) | Typical duration before any gazetted rollback |
|---|---|---|
| Most EU | Visa exemption | 60 days |
| USA, Canada, Australia | Visa exemption | 60 days |
| Japan, South Korea | Visa exemption | 60 days |
| China | Visa exemption (has been temporary in recent years) | 60 days |
| India | Visa on arrival (rules move) | Often 15 days |
| Russia | Visa exemption | Often 90 days |
The approved (not yet gazetted) rollback framework was described as a return to 30 days for most of the 60-day list, with a smaller set of island states at 15, and a tighter visa-on-arrival list. Treat every row as verify before you fly. Thai Embassy, not a hostel whiteboard.
Tourist Visa (TR)
For stays longer than the exemption you expect on the day you land, apply for a Tourist Visa (TR) at the Royal Thai Embassy in London before travel:
- Single-entry TR: 60 days, extendable by 30 (total 90). Fee commonly £30 — verify on the embassy page.
- Multiple-entry TR (METV): multiple entries over 6 months, 60 days per entry. Fee commonly £150.
Typical file: passport, form, two photos, proof of accommodation, flight itinerary, bank statement (often cited around £5,000+ or equivalent), employment or self-employment letter. We will not invent a 2026 document checklist that the embassy then changes on a Tuesday.
Long-stay options
For digital nomads, retirees, and people who have stopped pretending this is a holiday:
Non-Immigrant Visa O (retirement)
- Age 50+
- Income commonly cited at 65,000 THB/month or 800,000 THB in a Thai bank — verify the current embassy figures
- 90-day initial stay, extendable to 1 year (renewable annually)
- Apply at a Thai Embassy/Consulate before arrival
Non-Immigrant Visa B (business/work)
- Required for anyone working in Thailand
- Sponsored by a Thai employer
- Leads to a work permit
- Remote work for a foreign firm on a tourist stamp is the thing people do and the thing that is not the same as permission
Thai Elite
- Government-run long-stay membership
- Options have been advertised from about ฿600,000 (~£13,600) for 5 years to ฿2,000,000 (~£45,500) for 20 years — verify current packages; we are not a broker
- No age/income screen in the brochure sense
- Airport VIP and concierge are the product
Long-Term Resident (LTR)
- Introduced 2022 for wealthy or skilled categories
- 10-year visa with work permission in the relevant tracks
- Categories: wealthy global citizens, wealthy pensioners, work-from-Thailand professionals, highly skilled professionals
- Thresholds are high. Read the Board of Investment page, not a YouTuber.
Overstay
Thai immigration treats overstay as a tariff first and a ban when you make it a police matter.
| Overstay | Penalty |
|---|---|
| 1 day | ฿500 |
| Each day after | ฿500/day, commonly capped at ฿20,000 |
| Caught in-country by police | Detention, fine, deportation, and a re-entry ban (often cited 1–10 years depending on length) |
If you discover you have overstayed, present yourself at Immigration or at the airport on the way out. Voluntary surrender is treated less badly than being found. Do not “hide until the flight”.
Land borders and “visa runs”
Exiting and re-entering to reset the exemption clock used to be a lifestyle. Officers now have discretion:
- Multiple land entries draw questions
- They can refuse entry or grant a shorter stay
- Two consecutive exemption entries at land borders is often fine; a third in a row is how you collect a lecture
- Air arrivals generally face less of this than land booths
Myanmar, Cambodia, Laos, and Malaysia crossings each have their own hours and moods. Getting there.
Health and customs
- No routine mandatory vaccinations unless you are arriving from a yellow-fever area (then the certificate)
- COVID certificates are not required (dropped 2023)
- Sensible jabs: Hepatitis A and B, typhoid, tetanus/diphtheria. Consider Japanese encephalitis and rabies for long rural stays. Health and safety
