📅 Thai Tax Residency Day Counter

180+ days in Thailand in a calendar year = Thai tax resident. Enter your entry/exit dates and see exactly where you stand — including a safe buffer warning.

How days are counted

• Any part of a day present in Thailand counts — land at 23:59 and it's a day
• Both arrival AND departure days count
• The calendar year is Jan–Dec; residency resets every January 1st
• Visa runs reset nothing — only physical presence matters

Why the count matters

Crossing 180 days makes you a Thai tax resident, which activates remittance taxation of foreign income under 2024+ rules. Read the full explainer → or check whether your transfers are affected: Remittance Tax Checker.

Your dates never leave this browser. Border stamps are the authoritative record — keep photos of them.
