Thailand entry requirements: complete 2026 checklist

International travel to Thailand is fully open in 2026, but entry is not a matter of showing up and walking through. You need the right visa or exemption, a completed TDAC, and documents immigration may ask for at the counter. Many travellers still confuse old COVID rules with today's requirements, and that confusion costs time at immigration.

At Thai Visa Centre in Bangkok, we prepare travellers every week who mixed up Thailand Pass with TDAC, or assumed exemption would cover a long stay. This guide is your practical checklist for June 2026. For a deeper scenario walkthrough, see our dedicated 2025 to 2026 entry guide.

What changed since COVID, and what did not

Pandemic-era entry was a moving target of Thailand Pass registrations, vaccination proof, and quarantine hotels. Normal immigration policy has returned, but one new requirement replaced the old paper arrival card. Use the table below to separate retired rules from what still applies in June 2026.

Requirement	COVID era (2020 to 2022)	June 2026
Thailand Pass	Required 2021 to 2022	Ended. Not used.
Vaccination proof	Sometimes required	Not required for entry
Pre-arrival PCR/ATK	Required at times	Not required
Quarantine	Hotel/isolation schemes	None
TDAC	Not yet live	Mandatory since May 2025
Visa / exemption	Limited schemes	Normal policy restored

Thailand welcomes all nationalities subject to standard immigration law. There is no special open-to-everyone waiver, but there is also no pandemic-era health gate at the border. Historical COVID guides: 2022 archive.

Choose your entry path

Most short-term visitors enter on one of three paths below. Your passport nationality determines which options are open to you. Pick the path that matches your trip length and purpose before you fly, because switching category at the counter is not guaranteed.

Visa exemption

Stay: Up to 60 days per entry (eligible passports)

Short tourism for nationalities on the official exemption list. Ideal when your passport qualifies, your trip fits within 60 days, and you have a clear return or onward ticket. Immigration may ask about accommodation and funds even on exemption, so carry proof even if no visa was required to board your flight.

Visa on Arrival

Stay: 15 days. 2,000 THB at eligible checkpoints.

Limited nationalities at designated air, land, and sea points when no embassy visit is practical. VOA is not available everywhere and not for every passport. Confirm your checkpoint accepts VOA before you travel, and carry cash for the fee plus the funds proof officers expect at the counter.

Read guide

Tourist e-Visa (TR)

Stay: Typically 60 days. Extendable in Thailand.

Nationalities not exempt and not on the VOA list who want a pre-approved stamp before flying. A tourist e-Visa reduces surprises at the counter because eligibility was checked during application. Allow embassy processing time, especially in peak season, and print or save your approval before check-in.

Remote workers, retirees, and spouses need correct non-immigrant or special visas before relying on repeated tourist entries. Browse all visa types.

Five-step pre-travel checklist

Work through these steps in order before your departure date. Skipping one step, especially visa category or TDAC, is the most common reason travellers lose time at immigration or receive a shorter stamp than they planned.

Step 1: Choose visa category

Decide whether you enter on exemption, VOA, tourist e-Visa, or a long-stay visa before you book non-refundable flights. TDAC is mandatory for everyone, but it does not replace this decision. Arriving on the wrong category is one of the most common reasons travellers get extra questioning or a shorter stamp than they expected.

Step 2: Apply for visa if needed

Use thaievisa.go.th for e-Visa categories and follow your embassy instructions for paper applications. Allow processing time beyond the stated minimum, because peak season queues grow quickly. Double-check passport validity, photo specs, and financial proof before you pay fees, because re-submissions cost time.

Step 3: Submit TDAC

Complete TDAC within 72 hours of arrival on the official immigration domain only. One submission per passport holder, including infants. Save the confirmation email and a screenshot offline. TDAC replaces the old TM6 paper card, not Thailand Pass and not a visa approval.

Step 4: Pack documents

Keep tickets, funds proof, insurance, visa printout, and TDAC confirmation in hand luggage, not only in checked bags. Officers can ask for any of these at the counter even when your airline already checked you in. A phone folder with PDF copies plus paper backup is the safest approach.

Step 5: Plan post-entry compliance

Know your stamp length, extension options, and reporting duties before you land. Photograph your passport stamp and set a calendar reminder two weeks before expiry if you might extend. Long-stay holders should confirm TM30 and 90-day rules for their visa category on day one, not after a problem at extension time.

TDAC: mandatory for every foreign visitor

Since 1 May 2025, all non-Thai nationals must complete TDAC online before entry by air, land, or sea. Submit within 72 hours of arrival using Thailand time. The form is free at tdac.immigration.go.th and is required on every entry, including for long-stay visa holders returning from a holiday abroad.

Avoid copycat sites charging fees. We offer help at our TDAC service page.

Remember: TDAC is registration only. Immigration still decides admission based on visa category, funds, tickets, and discretion at the counter. A completed TDAC does not guarantee entry.

Documents to carry

Immigration officers may request any of the following at the counter. Keep copies accessible on your phone and in hand luggage, not only in checked bags. Requirements vary by entry path, but carrying the full set avoids delays when an officer asks for extra proof.

Passport with 6+ months validity recommended. VOA requires at least 30 days beyond your arrival date.
Return or onward ticket within your permitted stay length. Immigration compares ticket dates to your stamp.
Proof of accommodation: hotel booking or host address that matches what you entered on TDAC.
Proof of funds. VOA commonly expects 10,000 THB solo or 20,000 THB family equivalent in cash or accessible balance.
Visa approval printout or digital e-Visa if you are not entering on exemption.
TDAC confirmation: screenshot and email accessible offline in case airport Wi-Fi fails.
Travel insurance, strongly recommended. Mandatory for some visa categories such as retirement and certain long-stay routes.

Common entry mistakes

These errors show up repeatedly in our Bangkok office consultations. Most are avoidable with a fresh checklist and official sources, not forum posts from 2021 or 2022.

Relying on outdated COVID checklists that still mention Thailand Pass, vaccination proof, or quarantine hotels. Those rules ended years ago. TDAC is the current mandatory pre-arrival step.
Assuming TDAC replaces a visa. TDAC is arrival registration only. Immigration still decides admission based on your visa category, funds, tickets, and discretion at the counter.
Submitting TDAC on copycat sites that charge fees. The official form is free at tdac.immigration.go.th. Third-party sites may collect data without delivering a valid confirmation.
Entering repeatedly on visa exemption when your real plan is long-term stay or remote work. Officers compare entry history and may deny or shorten stamps. Choose DTV, retirement, or another proper category instead.
Arriving at a land border that does not offer VOA for your nationality when you counted on getting one. Confirm checkpoint capability before an overland trip from Cambodia, Laos, Malaysia, or Myanmar.
Storing all documents in checked luggage or cloud-only storage with no offline access. Immigration questions happen at the counter, often before you collect bags or when airport Wi-Fi is unreliable.

Health and insurance

COVID vaccination is not required for entry in 2026. Travel insurance is not universally mandatory for short tourists, but it is strongly recommended because Thai hospitals expect payment for uninsured care. Some visa types such as retirement and LTR require approved insurance meeting category minimums. Authorities may issue health advisories without reinstating Thailand Pass, so check MFA and airline notices before flying.

After entry: stay legal

Admission at the border is only the first step. What you do after landing determines whether your next extension, re-entry, or visa renewal goes smoothly. Long-stay holders should treat these obligations as seriously as the entry checklist above.

Leave before stamp expiry or apply for an extension at immigration before the expiry date. Even one day over creates a fine and an immigration record.
TM30 address registration when you change accommodation. Hotels usually file for guests; apartments need the landlord or juristic person to report.
90-day reporting for long-stay visa holders who are not on annual reporting tiers such as some LTR or Privilege members.
Re-entry permit before leaving mid-extension on single-entry visas. Without it, your extension may be cancelled when you exit.
Match activity to visa type. Tourism stamps do not authorise employment in Thailand, including many remote-work arrangements.

Overstay fines run 500 THB per day capped at 20,000 THB. Enforcement trends: immigration crackdowns guide.

Land borders vs airports

Major airports such as BKK, DMK, Phuket, and Chiang Mai handle most tourist traffic with standard TDAC and visa checks. Land borders may apply stricter questioning on re-entry patterns and offer limited VOA availability for some nationalities. Confirm your checkpoint accepts your nationality and entry method before travelling overland from Cambodia, Laos, Malaysia, or Myanmar.

Frequently asked questions

Quick answers to the questions we hear most often at Thai Visa Centre. Rules change, so verify against official sources before you travel if your trip is weeks away.

Q:Is Thailand Pass still required?

A:No. Thailand Pass ended in 2022 and is not used at any checkpoint today. TDAC replaced the paper TM6 arrival card, not Thailand Pass. If an old blog or forum post still mentions Thailand Pass, ignore it and complete TDAC instead.

Q:Can I enter without a visa?

A:Only if your nationality qualifies for visa exemption on the official list published by Thai immigration. Everyone else needs VOA at an eligible checkpoint or a pre-approved visa before travel. Exemption gives tourism stays, not permission to work or live long term.

Q:Is TDAC the same as ETA?

A:No. TDAC is live and mandatory for all foreign nationals on every entry. A separate electronic travel authorisation for visa-exempt countries has been discussed in policy announcements but is not a substitute for TDAC in 2026. Complete TDAC on the official immigration site regardless of other programmes you read about online.

Q:Do children need TDAC?

A:Yes. Each foreign passport holder needs their own TDAC submission, including infants and toddlers. Parents complete a separate form per child. One family cannot share a single TDAC under one adult passport.

Q:Are land borders different from airports?

A:Major airports such as BKK, DMK, Phuket, and Chiang Mai handle most tourist traffic with standard TDAC and visa checks. Land borders may apply stricter questioning on re-entry patterns and offer limited or no VOA for some nationalities. Confirm your checkpoint accepts your entry method before travelling overland.

Q:Is travel insurance mandatory for tourists?

A:Not universally mandatory for short tourism entry in 2026, but strongly recommended because Thai hospitals expect payment for uninsured care. Retirement, LTR, and some other visa categories require approved insurance meeting category minimums. Carry a policy that covers inpatient treatment even on tourist paths.
