Phuket is the base for a lot of long-stay readers, so Thai tax still matters. The rules are still moving, so here's the plain version for 2026, and why you should talk to an accountant.

Tax here changed in 2024, and it's still moving. Worth getting right.
Right, the usual warning: I'm not an accountant, tax is personal, and this area is genuinely in flux right now. So treat this as a heads-up on what's changed and what to ask about, not advice you act on. For anything real, pay a Thai tax accountant, it's cheap next to getting it wrong.
This is the line that matters. If you spend 183 days or more in Thailand in a calendar year, you're a Thai tax resident. Under that, and you generally aren't. A lot of people don't realise that crossing the half-year mark changes their tax position here.
What changed in 2024
For years, foreign income was only taxed if you brought it into Thailand in the same year you earned it, which was easy to work around. From 2024 that closed. Now, as a tax resident, foreign income you remit into Thailand can be taxed whatever year you earned it. The key word is remit, it's about money you actually bring in, not money you earn abroad and leave abroad.
The 2026 change everyone's watching
There's a proposed update, expected around the early-2026 filing season, that softens this. The idea: foreign income you bring in during the same year you earn it, or the following year, would be exempt. Bring it in later than that and it's taxed at the normal progressive rates, which run from 5 to 35 percent. At the time of writing it's still being finalised, so don't build your plans around a forum post.
Don't forget your home country
Being taxed in Thailand doesn't automatically mean you stop owing tax back home, and double-tax treaties decide who gets what. This is exactly the kind of thing a cross-border accountant sorts in one conversation.
What to actually do
Work out whether you'll hit 183 days this year.
Keep records of what you earn, where, and when you bring it into Thailand.
If you're moving meaningful sums, get a Thai tax accountant before you do it, not after.
Don't rely on what worked a few years ago, the rules have moved.

FAQ
Am I a tax resident in Thailand?
You're a Thai tax resident if you spend 183 days or more in Thailand in a calendar year. Below that, you generally are not.
Does Thailand tax foreign income?
Since 2024, Thailand can tax foreign income that a tax resident brings (remits) into the country. A proposed 2026 change would exempt income remitted in the same year it's earned or the following year, with later remittances taxed at 5 to 35 percent. It is still being finalised, so check with an accountant.
Do I still pay tax in my home country?
Possibly. Being taxed in Thailand doesn't automatically end your home-country obligations, and double-tax treaties decide who taxes what. A cross-border accountant can tell you where you actually stand.
