Health declaration T8 form: what happened to it?
Search results still mention the T8 health declaration form, a paper card every arrival filled in during the COVID-19 pandemic. Travellers email us asking where to download it before their flight. Here is the straight answer for 2026: the T8 is no longer required.
What replaced it is TDAC, the Thailand Digital Arrival Card. Complete it within 72 hours of landing at tdac.immigration.go.th for every entry, including repeat visits on long-stay visas.
Paper pandemic form no longer used at border
Digital arrival card since 1 May 2025
Submit before every international entry
Do not confuse with TDAC requirement
What was the T8 form?
The T8, also called the health declaration form, was a paper declaration asking about:
- Recent travel history
- COVID-19 symptoms
- Contact with infected persons
- Vaccination status during later pandemic phases
Airlines and immigration officers collected it alongside Thailand Pass approvals and COE documents when Thailand operated strict pandemic entry controls (roughly 2020–2022). The T8 was not a visa. It did not extend your stay. It was a public-health screening tool only.
Is the T8 still required in 2026?
No. As of 2026, standard entry to Thailand does not include:
- T8 paper health forms
- Thailand Pass registration
- Certificate of Entry (COE)
- Mandatory quarantine (ASQ / Sandbox)
- COVID-specific insurance for standard tourist entry
If a third-party website still sells T8 form assistance, it is outdated.
What replaced the T8?
Thailand Digital Arrival Card (TDAC)
- Submit up to 72 hours before arrival (Thailand time)
- Free on the official site: tdac.immigration.go.th
- Applies to visa holders, visa-free travellers, and VOA applicants
- Required on every entry, including repeat visits
TDAC collects travel and contact details for immigration. It is not a symptom questionnaire like the old T8, though health policies can change during disease outbreaks. We help travellers avoid TDAC mistakes: TVC TDAC assistance.
Current entry checklist (post-T8 era)
| Step | Requirement |
|---|---|
| 1 | Valid passport and appropriate visa or exemption via the e-Visa portal |
| 2 | TDAC completed before arrival |
| 3 | Onward ticket, accommodation proof, funds if asked |
| 4 | Travel insurance is recommended but not a standard tourist entry requirement |
| 5 | Special health measures apply only if announced for specific outbreaks |
Health screening during outbreaks
Thailand can temporarily reintroduce fever screening, arrival questionnaires, or vaccination proof when global health events warrant it, as with past monkeypox or COVID surges. When active, requirements appear on MFA announcements, e-Visa notices, and airline pre-departure checks. These are separate from the old standing T8 requirement. Check within two weeks of travel.
What about quarantine and COVID insurance?
Mandatory quarantine for vaccinated or unvaccinated tourists ended in 2022. COVID insurance mandated for entry is no longer a standard requirement. General travel health insurance remains strongly recommended.
Common mistakes we see
- Downloading obsolete T8 PDFs from old blog posts
- Completing TDAC more than 72 hours early; submission windows matter
- Assuming no forms at all means no TDAC. TDAC is mandatory
- Confusing TDAC with 90-day reporting for long-stay holders after entry
Planning checklist before you travel or relocate
Confirm your entry category, passport validity, and return plans before booking non-refundable flights or long hotel stays. Immigration officers compare your stated purpose with your visa stamp, prior entry history, and supporting documents at the counter.
Register your address through TM30 when required, complete TDAC before every arrival, and keep copies of lease agreements, insurance policies, and embassy correspondence in one folder. These records matter for extensions, tax filings, and unexpected compliance checks.
If your situation involves work, marriage, retirement funds, or property purchase, book a case review with our Bangkok team early. Small document gaps that seem minor at arrival become expensive fixes at extension season.
Frequently asked questions
Q:Where do I download the T8 form?
You do not need to. It is discontinued. Use TDAC instead.
Q:Did TDAC replace the T8?
Functionally, TDAC replaced paper arrival cards (TM6) and the pandemic-era health paperwork bundle. For 2026 travellers, TDAC is the relevant pre-arrival form.
Q:Do airlines still ask for health declarations?
Some carriers use their own generic health attestations independent of Thailand. That is airline policy, not the Thai T8.
Q:Do retirees need different health forms?
Retirees need TDAC on entry plus health insurance meeting O-A visa minimums. See our retiree insurance guide, not the T8.
Q:Will Thailand bring back Thailand Pass?
Thailand Pass was suspended and replaced by normal entry plus TDAC. Future outbreaks could trigger new systems, so monitor MFA if news breaks.
Q:When was this guide last reviewed?
June 2026. Embassy fees, financial thresholds, and procedures change without notice. Verify all requirements within two weeks of applying.
