Do retirees from the US pay taxes on their income in Thailand?

This is not a correct statement, and you should consult a USA/THAI tax attorney if you are bringing in a substantial amount of money other than your U.S. paid Social Security/Pension.

If you live in Thailand for over 180 days, you are considered a resident and there is a very good chance you will be challenged at some point to declare all income earned in or after 2024 that you brought into the country (but everything is in the air right now).

You can apply a tax credit for taxes you have already paid in a foreign country. Article 2 of the DTA might help.

"Social security benefits and other similar public pensions paid by a Contracting State to a resident of the other Contracting State or a citizen of the United States shall be taxable only in the first-mentioned State."

This means that your U.S. Social Security income, even when brought into Thailand, is only taxable by the United States and not by Thailand. This provides protection to your Social Security income, ensuring it is not subject to double taxation.

Providing Tax advice, NO!

Just curious, if on a retirement visa, how can one earn income in thailand? 🤔

The US taxes your global income whether you are a tax resident of the US or not. Thailand taxes any income you earn inside the country. Also all income you remit to Thailand is assessable for Thai tax, you can claim a credit for any tax already paid on the money you remit and certain income is not subject to Thai tax as defined in the dual tax agreement between the US and Thailand. Dividends, Interest etc can be taxed in Thailand. SS can't be taxed in Thailand but other pensions can be subject to Thai tax. Best you read, or get someone skilled to read, the DTA between the 2 countries

Never was the case.

That was never the case.

The case was that any income earned in a different year would not have taxes due if it was remitted to Thailand in the following year or later. For retirees that basically meant their income wouldn't be taxed because it was retirement income from earnings long ago.

As of 2023 the policy has changed to tax income regardless of when it was earned once it is remitted to Thailand.

But as long as you already paid taxes on the income and your country has a dual taxation treaty with Thailand, you don't be double taxed.

This only applies if you are a tax resident of Thailand (180 days in the country)

How this will actually work in policy is unknown as 2024 is the first year this goes into effect meaning it won't come up until the beginning of 2025 during tax season.
