LTR Royal Decree 743 — Foreign Income Tax 2026

Full LTR guide: Long-Term Resident visa 2026 · Thai tax for foreign residents

What Royal Decree 743 actually does

Checked 1 August 2026: the Thai Revenue Department text and BOI's English translation match on the core rule. Section 5 exempts the three named LTR categories for assessable income derived in the previous tax year from employment or business carried on abroad, or property situated abroad, and brought into Thailand. Section 6 makes the benefit subject to Revenue Department qualifications, rules, procedures, and conditions.

This is not a blanket "LTR pays no tax." It is limited by category, income source, timing, and the conditions attached to the decree. Highly-Skilled Professionals receive a separate benefit: the official briefing describes a 17% rate for qualifying employment income in targeted industries.

Who qualifies (and who does not)

✓ Wealthy Global Citizen — named in Section 5
✓ Wealthy Pensioner — named in Section 5
✓ Work-from-Thailand Professional — named in Section 5
Not a Section 5 category: Highly-Skilled Professional — the decree instead provides the separate employment-income treatment described above
Other visa types: DTV, Non-O, O-A, ED, Privilege, and SMART are not among the three Section 5 categories. Their tax position must be checked separately under the Revenue Code and any applicable treaty; this decree alone does not determine the result.

Application and filing

No exemption application or prior approval: this is the Revenue Department's current published instruction for the foreign-source income exemption.
No domestic-source income: if the holder has only exempt foreign-source income remitted into Thailand, the briefing says no personal income tax return is required.
Domestic-source income: the holder must file a personal income tax return.
Keep evidence: retain the LTR status documents and records showing the source, tax year, and remittance of income so the Section 5 conditions can be demonstrated if questioned.

Common mistakes in 2026

Assuming DTV has the same treatment. DTV is not one of the three categories named in Section 5. That does not by itself prove a tax bill; the person's facts and the wider tax rules still matter.

Confusing the two LTR benefits. The foreign-source income exemption is for the three Section 5 categories. The separate 17% treatment is for qualifying Highly-Skilled Professional employment income.

Filing an unnecessary exemption application. The current official briefing says no application or prior approval is required for the foreign-source income exemption.

Applying the exemption to every receipt. Thai-source income and receipts outside Section 5 need a separate tax analysis. The decree's source and timing language matters.

What cannot be responsibly estimated here

Personal tax savings, tax due on a particular remittance, audit risk, and professional fees depend on the income type, source year, other Thai income, treaty position, deductions, and evidence. Earlier examples on this page were not supported by an official source and have been withdrawn. Obtain case-specific advice before relying on the exemption.
