TL;DR
LTR Visa (4 sub-classes) ตามพ.ร.ฎ. 743/2565 + ประกาศกระทรวงการคลัง 1 พ.ย. 2565 ให้สิทธิยกเว้นภาษีรายได้ต่างประเทศที่นำเข้าไทยตามมาตรา 3 พ.ร.ฎ. — เป็นทางออกถูกกฎหมายเดียวที่เหลือหลัง POR 161; เงื่อนไข: WGC ต้องมีสินทรัพย์ ≥ USD 1M + รายได้ ≥ USD 80K/ปี + ลงทุนในไทย ≥ USD 500K; WP ≥ 50 ปี + รายได้บำนาญ ≥ USD 80K; WFTP ≥ USD 80K/ปี + นายจ้างมีรายได้ ≥ USD 150M; HSP ≥ USD 80K/ปี ในอุตสาหกรรมเป้าหมาย; ต้องลงทะเบียนเพิ่มที่กรมสรรพากร + ต่ออายุหลักฐานทุกปี
The LTR Visa (4 sub-classes under Royal Decree 743/2565 + Min. of Finance Notification 1 Nov 2022) grants statutory exemption for foreign-source income remitted to Thailand — the only clean legal carve-out left after POR 161. Thresholds: WGC needs USD 1M assets + USD 80K/yr income + USD 500K Thai investment; WP age ≥ 50 + USD 80K pension; WFTP USD 80K/yr + employer revenue ≥ USD 150M; HSP USD 80K/yr in target industry. Separate LTR registration at the Revenue Department; renew evidence annually.
The statutory basis
**Royal Decree (พ.ร.ฎ.) 743/2565** issued by virtue of Revenue Code § 3 — exempts assessable income under § 40 (foreign-source) brought into Thailand in the same tax year, for LTR Visa holders.
**Ministry of Finance Notification dated 1 Nov 2022** sets implementation: LTR Visa holders must (i) register with the Revenue Department to obtain an LTR tax ID file, (ii) renew evidence annually, (iii) file Form ภ.ง.ด.95 in lieu of standard ภ.ง.ด.90 for the exempt portion.
**BOI Notification Ngor.6/2565** sets BOI qualification thresholds + workflow for the four sub-classes.
**POR 161/162 carve-out preserved:** the 2023 reform of the foreign-source remittance regime explicitly preserved the LTR exemption (Cabinet Resolution 18 Sept 2023).
Sub-class eligibility — the hard numbers
**Wealthy Global Citizen (WGC):** total assets ≥ USD 1M (audit-verified), personal income ≥ USD 80K/year for last 2 years, investment in Thailand ≥ USD 500K (Thai sovereign bonds / Thai REITs / Thai property / Thai PE), health insurance ≥ USD 50K coverage OR ≥ USD 100K deposit in Thai bank for 12 months.
**Wealthy Pensioner (WP):** age ≥ 50, passive pension/dividend income ≥ USD 80K/year (or USD 40K + USD 250K Thai investment), same health insurance / deposit rule.
**Work-from-Thailand Professional (WFTP):** employer (foreign-listed) revenue ≥ USD 150M for last 3 years, employee personal income ≥ USD 80K/year for last 2 years (or ≥ USD 40K + master's degree / IP holder / Series-A funded), 5+ years' relevant experience.
**Highly-Skilled Professional (HSP):** employed in BOI target industry, personal income ≥ USD 80K/year (or ≥ USD 40K + master's + 5 yrs experience, or no income floor if government employee). Target industries: next-gen automotive, smart electronics, affluent tourism, agri-tech, food, robotics, aviation, biotech, digital, biofuels, medical hub, defence.
The two-step registration workflow
**Step 1 — BOI LTR endorsement (4–8 weeks):** apply via the BOI LTR Visa portal (https://ltr.boi.go.th) with passport, evidence dossier (income, assets, employer, insurance), notarised translations where source is non-English. Endorsement letter issued; visa stamp at Thai Embassy of choice or in-country One-Stop Service Centre at Chamchuri Square Bangkok.
**Step 2 — Revenue Department LTR tax registration (2–4 weeks):** within 60 days of visa stamping, attend Revenue Department area office or e-file via RD e-Service with: LTR Visa page, BOI endorsement letter, foreign tax-residency certificate (if any), Thai bank-account confirmation. Receive LTR tax-file confirmation letter — quote on all future filings.
**Common failure mode:** skipping Step 2. Foreigners assume the BOI endorsement alone activates the exemption — it does not. Revenue Department treats unregistered LTR holders as standard residents and applies POR 161 in full.
Annual evidence stack
**Income proof:** prior-year tax return (home country) + employer letter + pay slips totalling ≥ threshold.
**Asset proof (WGC only):** auditor-verified personal balance sheet as at 31 Dec.
**Pension proof (WP only):** pension fund annual statement showing ≥ USD 80K paid.
**Insurance / deposit proof:** policy renewal certificate or Thai bank deposit slip + interest accrual.
**Thai investment proof (WGC):** broker confirmation, REIT statement, property title showing USD 500K maintained.
**Filing:** ภ.ง.ด.95 for exempt foreign income + ภ.ง.ด.90 for any Thai-source income, due 31 March.
Notarial chain — when notarisation enters the picture
**Foreign tax-residency certificate:** issued by home tax authority (HMRC SA300, IRS Form 6166, BZSt residency cert). Apostille from issuing state from 28 February 2027 (Thailand HCCH accession) — no longer requires home-embassy legalisation.
**Foreign auditor balance sheet (WGC):** translation must be certified by a Thai Notarial Services Attorney; original auditor signature Apostilled at home jurisdiction.
**Employer letter (WFTP):** signature notarised at home jurisdiction + Apostille; Thai certified translation by NSA.
**Pension statement (WP):** typically Apostille-ready from home pension fund. If private pension, notarisation of fund custodian's certificate may be required.
Common stacking mistakes to avoid
**Mixing exempt and non-exempt remittances in one account:** Revenue Department demands traceability. Use a dedicated Thai bank account for LTR-exempt remittances, separate from Thai-source income.
**Crypto off-ramps:** P2P crypto sales settled into a Thai bank are Thai-source service income — not foreign-source — even if the underlying crypto was held offshore. LTR exemption does not apply.
**Thai-listed dividends:** SET-listed dividends are Thai-source. LTR exemption never applies. Withholding remains at 10%.
**Failure to renew evidence:** Revenue Department auditors will reassess prior years' exemption if current-year qualification lapses. Maintain continuous insurance + minimum investment year-on-year.
คำถามที่พบบ่อย
If I lose LTR qualification mid-year (e.g., insurance lapse), do I lose the exemption for the whole year?+
Revenue Department practice (RD Newsletter Q1/2025): the exemption applies pro-rata to remittances received during the qualification window. Remittances after the lapse fall under standard POR 161 treatment. Cure within 90 days to preserve continuity; document the cure date.
Can my spouse and children remit foreign income tax-free under my LTR?+
Only if they are individually qualified LTR holders. Dependants on the LTR-Dependant visa do not automatically inherit the tax carve-out. A dependant earning their own foreign salary must remit it themselves and is taxed under POR 161 unless they hold an independent LTR.
Does LTR exemption cover capital gains on foreign property sale?+
Yes — capital gains are foreign-source under § 40 when arising outside Thailand. Document the disposal (sale-and-purchase agreement notarised + Apostille from situs country) and the bank trail. Settlement currency can be USD/EUR/THB; the Thai remittance triggers exemption.
How does LTR interact with foreign tax credits?+
If the foreign-source income is exempt under LTR, there is no Thai tax liability — therefore no foreign tax credit available (you cannot credit foreign tax against zero Thai tax). For non-exempt categories (Thai-source), the standard DTA credit mechanism applies via Form Ror.Ngor.21.
Will eIDAS-2 / e-Apostille streamline the LTR document chain?+
Yes — from Q4 2026 the DCA e-Apostille rollout means foreign tax-residency certificates Apostilled at home in e-format will be verifiable instantly at the Revenue Department's portal. Expect LTR registration lead time to compress from 2–4 weeks to 2–4 working days by 2027.
