🇺🇸 United States vs 🇹🇭 Thailand
Tax residency, treaties and PE risk compared.
| Dimension | 🇺🇸 United States | 🇹🇭 Thailand |
|---|---|---|
| Residency rule | Citizenship-based + Substantial Presence | 180 days in a calendar year |
| Day threshold | 183 days | 180 days |
| Warning band | from 122d | from 150d |
| Tax range | 10–37% federal + state | 0–35% |
| Tax treaties | 70+ | 61+ |
| PE risk | High | Medium |
| Digital nomad visa | No | Yes |
| Best for | US citizens optimising via FEIE ($126,500) and treaty benefits | Long-term remote workers on the DTV or LTR visa |
| Common pitfall | US citizens are taxed on worldwide income forever — there is no day-count exit. | Since 2024, foreign-source income remitted to Thailand IS taxable for residents. |
Verdict
United States and Thailand carry similar residency risk on day-count alone — the deciding factor is usually treaty coverage (70 vs 61) and your specific income mix.
