Thailand Stay Days Calculator
Track your Thailand stay duration, remaining allowed days, tax residency exposure, and overstay risk across multiple trips and visa types.
Enter your Thailand trip details
Select your visa type, choose the year, and enter your trip entry and exit dates. Leave exit date blank if you're still in Thailand.
How this works: Enter each trip to Thailand separately — entry and exit dates. We calculate total days in Thailand, your single-stay duration relative to your visa limit, and your progress toward the 180-day tax residency threshold.
Select a visa type and enter at least one entry date to continue.
How Thailand Stay Duration Rules Work
Visa validity vs. permitted stay
These are two different things. A tourist visa may be valid for 3 months (meaning you must enter Thailand within 3 months of issue), but once you enter, your permitted stay is 60 days from entry. Similarly, a retirement visa extension grants 12 months of permitted stay from the extension date — not from any original issue date.
Visa exemption and border runs
Most nationalities entering Thailand without a visa receive a 30-day permission to stay (some receive 45 days). You can leave Thailand and re-enter to receive a fresh exemption stamp — commonly called a 'border run'. However, immigration officers have discretion to deny entry to those who appear to be using border runs to live in Thailand long-term without an appropriate visa.
In-country extensions
Most visa types allow at least one in-country extension at any Thai immigration office. Tourist visas and exemption stamps can be extended by 30 days (฿1,900 fee). This is a one-time extension — you cannot extend an already-extended stay without leaving Thailand first.
Tax residency threshold
Under Thai tax law, spending 180 days or more in Thailand during a calendar year (January to December) makes you a Thai tax resident for that year. This means you may be liable for Thai income tax on certain income brought into Thailand. The threshold is based on physical presence — not your visa type. Consult a qualified tax advisor for guidance on your specific situation.
Overstay consequences
Overstaying is taken seriously in Thailand. Fines of ฿500/day apply (up to ฿20,000 maximum), and overstays above 90 days trigger re-entry bans of 1–10 years depending on length. Always leave before your permission to stay expires. If you're unsure of your expiry date, check the stamp in your passport — it shows the 'permitted to stay until' date, not the visa expiry.
Immigration rules in Thailand are interpreted with discretion by individual officers and can change without public notice. This guide reflects general practice as of 2026 — always verify with the Thai Immigration Bureau.

About This Thailand Stay Days Calculator
This free tool helps expats, tourists, retirees, and digital nomads track their total days spent in Thailand across multiple trips and visa types. By entering your entry and exit dates for each trip, the calculator shows your total days in Thailand for a given calendar year, your longest single stay relative to your visa type's permitted duration, and your progress toward the 180-day tax residency threshold.
The tool covers all major Thailand entry types — visa exemption stamps (30 or 45 days), tourist visas (60 days), the DTV visa (180 days per entry), and annual extension visas including retirement, marriage, work, and education visas. Each visa type has specific permitted stay durations, financial requirements, and renewal rules that are reflected in the tool's guidance.
Understanding your Thailand stay duration is important for two main reasons: first, to avoid accidental overstays (which incur fines of ฿500/day and can result in re-entry bans), and second, to track your exposure to Thai tax residency (triggered at 180 days in a calendar year). This tool is informational only. For tax and immigration guidance specific to your situation, consult a qualified advisor.
