Thailand has been one of the world's most visited countries for years – not only as a travel destination, but also as a hub for long-term travelers, retirees, and digital nomads. By 2025, the country will be more connected, more digital, and offer more diverse travel options than ever before.

In 2025, a trip to Thailand requires more than just a plane ticket: New systems, updated visa regulations, and more sophisticated scams make thorough preparation essential. To ensure you're well-prepared, we've compiled the 20 most important tips for your trip to Thailand this year.

Basics of Law and Immigration

1. Digital Entry Card for Thailand (TDAC)

The Thailand Digital Arrival Card (TDAC) has replaced the old paper form TM6 for entry and exit. Travelers must complete it online before arrival. You can start filling it out up to three days before your trip. Airlines and immigration authorities may conduct checks, so you should not skip this step to avoid delays.

2. Visa and entry requirements

Most travelers can still enter visa-free for 30 to 60 days (depending on their nationality) under visa waiver and bilateral agreements. Their passport must be valid for at least six months. Travelers may be required to provide proof of onward travel or sufficient funds.

3. Proof of onward travel

Immigration officials or airlines may request proof of onward or return travel. If you have flexibility, book a refundable option or use a flight reservation service.

4. TM30 notification

By law, your landlord or hotel must report your stay to the immigration authorities using a TM30 form. This report is important for visa extensions or other immigration procedures.

5. Long-term visa options

Are you planning a longer stay? Thailand offers visas for every lifestyle:

  • Retirement visa for retirees.
  • Destination Thailand Visa (DTV) for remote workers, freelancers and cultural tourists.
  • Long-term residence visa (LTR) for skilled workers, investors and highly qualified individuals.
  • The Thailand Elite Visa is aimed at premium travelers who value comfort and longer stays.

    • 6. 90-day report

    If you stay in Thailand for more than 90 days, you must report your address to the local immigration authorities every 90 days. This 90-day reporting requirement is not a visa requirement, but a legal obligation.

    7. Carrying identification

    Foreigners are legally required to carry identification. For everyday use, a copy of the passport is usually sufficient.

    8. Currency & Payments

    The national currency is the Thai Baht (THB). ATMs charge a fee of approximately 220 THB per withdrawal. Cash is still widely used, but credit and debit cards are accepted in larger hotels and shopping malls.

    Practical travel tips for Thailand

    1. Tips for transport

    For safe journeys, use Grab (a ride-hailing app). Taxis should use a meter – if not, negotiate the price beforehand. Tuk-tuks are fun, but more expensive. You'll need an international driving permit for rental cars and scooters.

    2. SIM cards & Wi-Fi

    Local SIM cards from AIS, DTAC, and TrueMove are inexpensive and readily available at the airport. Free Wi-Fi is widely available in hotels and cafes, but speeds vary.

    3. Weather preparation

    Pack light cotton clothing, sunscreen and an umbrella/rain jacket if you are traveling during the monsoon season.

    4. Cultural Etiquette

    Dress modestly in temples (shoulders and knees covered). The traditional greeting is the wai (palms pressed together, slight bow). Show respect to monks and the royal family.

    5. Shoe-off rule

    Shoes must always be removed when entering houses, temples, and some small shops.

    6. Health and Safety

    Drink bottled water, consider travel vaccinations, and take out travel insurance. Petty theft can occur, especially in tourist areas.

    7. Avoid fraud

    Common scams involve jet ski rentals, overpriced gemstones, and tuk-tuk tours with supposedly "special" attractions. Use trusted providers. In case of problems:

  • Tourist Police: 1155 (English-speaking support)

    • 8. Street food & gastronomy

    Thai street food is delicious and safe if you choose the busier stalls. If you don't like it spicy, you can tell the vendor "mai phet" (not spicy). Tipping is not mandatory, but it's appreciated if you round up the bill.

    9. Electricity and plugs

    Thailand uses 220V, and the plug types are A, B, and C. Bring a universal adapter.

    10. Respect for religion and culture

    Never touch Buddha statues and do not point your feet at people or religious objects. Dress appropriately in holy places.

    11. Sustainable travel

    Support ecotourism: Avoid single-use plastics, respect wildlife, and book tours with local providers.

    12. Language basics

    It helps to learn a few Thai phrases. Examples:

  • "Hong Nam?" – Where is the toilet?

    • Always add "ka" (for women) or "krub" (for men) at the end as a courtesy. Additionally, add "wai" to emphasize the respect.
