Your visa status only determines how long you can stay. But regardless of visa type, every traveler must present the same set of documents at the immigration counter. This guide covers the mandatory entry requirements for Thailand in 2026 — including the TDAC digital arrival card that trips up more travelers than anything else.
The #1 Mistake Travelers Make
Visa ≠ Entry Form. Even if you do not need a visa (93 countries are visa-exempt), you MUST still file a Thailand Digital Arrival Card (TDAC) before you clear immigration. These are two completely separate requirements. Without a TDAC, you will be sent to a kiosk at the airport — adding 30-60 minutes to your arrival.
1. The Thailand Digital Arrival Card (TDAC)
The TDAC is a mandatory digital form for every foreign national entering Thailand. It replaced the old paper TM.6 arrival card. You must complete it before you arrive — immigration officers will scan your QR code at the counter.
What the TDAC Collects
- Passport data: Full name (exactly as printed in your MRZ line), nationality, passport number, date of birth, expiry date.
- Flight information: Airline, flight number, date of arrival.
- Accommodation in Thailand: Hotel name and address, or your host's address if staying privately.
- Purpose of visit: Tourism, business, transit, or other.
How to File
- When: Up to 12 months before arrival. We recommend at least 72 hours before departure.
- Where: The official government portal (free) or through an assisted filing service like TDAC.info ($29 with error review).
- Output: A QR code delivered to your email. Save it on your phone and print a backup copy.
Common TDAC Rejection Reasons
Passport number typo: The most common error. One wrong digit and your QR code will not match at the counter.
Name mismatch: Your TDAC name must exactly match the MRZ line in your passport (not your preferred name).
Wrong date format: Confusing DD/MM/YYYY with MM/DD/YYYY causes mismatched arrival dates.
Missing accommodation: You must provide a Thai address — 'traveling around' is not accepted.

2. Passport Requirements
Your passport must meet two non-negotiable conditions — fail either one and you will be denied boarding or entry:
- 6-month validity rule: Your passport must have at least 6 months of validity remaining from your date of entry into Thailand. Airlines enforce this at check-in — if your passport expires within 6 months, you will not be allowed to board.
- Blank visa pages: You need at least 1 blank page for the entry stamp. Some immigration offices require 2 blank pages.
- Damaged passport: A cracked laminate, water damage, or illegible pages can result in denial at the immigration counter. If in doubt, renew before you travel.
3. Proof of Onward Travel
Immigration officers can ask for proof that you plan to leave Thailand within your permitted stay. This is enforced more strictly for:
- Solo travelers arriving on one-way tickets
- Travelers using Visa on Arrival (VOA)
- Anyone who has been flagged for previous overstays or repeated visa-exempt entries
What counts: A confirmed flight booking, bus ticket to a neighboring country, or ferry ticket. The booking must show departure within your visa duration (e.g., within 60 days for visa-exempt travelers). Flexible/refundable bookings are fine — they just need to exist.
4. Proof of Funds
Thailand requires proof of sufficient funds for your stay. The amounts are:
| Entry Type | Required Amount | Notes |
|---|---|---|
| Visa-Exempt (60 days) | 20,000 THB (~$600 USD) per person | Cash preferred; bank statement also accepted |
| Visa on Arrival | 10,000 THB (~$300 USD) per person | Cash only at VOA counter |
| Tourist Visa (TR) | 20,000 THB per person | Cash or bank statement |
| Family/Group | 40,000 THB per family | Regardless of family size |
How it works in practice: Spot checks are random, not universal. You are more likely to be checked if you are traveling solo, arriving on a one-way ticket, have limited stamps in your passport, or if the immigration officer has any reason to question your trip. Carry the cash anyway — being caught without it means denied entry.
5. What Immigration Officers Actually Check
Here is the sequence at the immigration counter — knowing this helps you prepare everything in advance:
TDAC QR Code Scan
The officer scans your QR code first. If it fails (typo, expired, not filed), you are sent to a kiosk to file on the spot. This adds 30-60 minutes.
Passport Check
They verify your identity photo, check passport validity (6+ months), and confirm your visa status (exempt, VOA, or visa sticker).
Entry Stamp
You receive a stamp with your permitted stay duration. Check the date immediately — errors happen and are very difficult to fix later.
Spot Checks (Random)
Some travelers are asked for proof of onward travel, accommodation booking, or proof of funds. Have these accessible — not buried in your checked luggage.
6. Overstay Rules & Penalties
If you stay past the date stamped in your passport, you are officially on "overstay." Penalties escalate fast:
| Overstay Duration | Penalty | Consequence |
|---|---|---|
| 1-90 days | 500 THB per day (max 20,000 THB) | Fine paid at airport departure; no ban if voluntary |
| 91 days - 1 year | 20,000 THB fine | 1-year re-entry ban |
| 1-3 years | 20,000 THB fine | 3-year re-entry ban |
| 3-5 years | 20,000 THB fine | 5-year re-entry ban |
| 5+ years | 20,000 THB fine | 10-year re-entry ban |
| Caught by police (any duration) | Arrest + deportation | 5-year ban + criminal record |
Voluntary vs. Caught
If you voluntarily report your overstay at the airport when leaving, penalties are milder (fine only, shorter bans). If you are caught by police during a random check, raid, or traffic stop, the consequences are much worse — arrest, detention, deportation, and a 5-year ban regardless of overstay duration.
7. Special Cases
Children & Infants
Every child — including infants — needs their own passport, their own TDAC filing, and their own entry stamp. There is no exemption for minors. For the occupation field on the TDAC, use 'Student' for school-age children or leave blank for infants.
Transit Passengers
If you are transiting through Thailand (connecting flights within the same terminal), you do not need a TDAC or visa. However, if your transit requires you to exit the secure area, re-check luggage, or change terminals, you must clear immigration — which means you need both a TDAC and appropriate visa status.
Land Border Entries
Visa-exempt travelers entering by land (from Malaysia, Cambodia, Laos, or Myanmar) receive the same 60-day stamp as air arrivals. However, land entries are limited to 2 per calendar year. Air entries have no annual limit. The TDAC is required for both air and land entries.
