The 2024 Thai tax changes have created real confusion among expats living in Phuket. This guide cuts through the noise with the key facts — but always get professional advice for your specific situation.
⚠️ 2024 Tax Rule Change That Affects You
From January 2024, Thailand taxes foreign income remitted to Thailand in the SAME tax year it was earned — previously only income remitted in the same year it was earned was taxable. The old 'one year delay' planning strategy is gone.
This affects long-term expats with offshore income who are Thai tax residents. If you have foreign income and are planning to bring money into Thailand, this is critical to understand.

Who is a Thai Tax Resident?
The simple rule: if you spend 180 or more days in Thailand in a calendar year, you are a Thai tax resident. This doesn't have to be consecutive days — it's the total count.
Long-term visa holders
If you hold an O, O-A (retirement), O-X (long-term resident), or LTR (Long-Term Resident) visa, you are almost certainly a Thai tax resident. Thailand assumes you're staying, and the tax authority treats you as resident unless you can prove otherwise.
Tourist visa holders
Most tourist visa holders stay less than 180 days per year and are not tax residents. However, if you're doing multiple 60-day border runs and hitting 180 days, you may be tax resident — and the Thai Revenue Department is increasingly tracking this.
Insider tip: Keep a record of your entry and exit stamps. If audited, you'll need to prove how many days you were in Thailand.
What Income is Taxable in Thailand?
Not all income you earn is taxable in Thailand. Here's the breakdown:
Income Earned IN Thailand (Always Taxable)
- Employment income (salary from Thai employer)
- Thai business income
- Rental income from Thai property
- Interest, dividends from Thai sources
If you earned it in Thailand, Thailand taxes it. No exceptions.
Foreign Income Remitted to Thailand (2024 Rule Change)
This is where the January 2024 change matters. Thailand now taxes foreign income that you remit to Thailand in the same tax year it was earned.
Example: You earned a ฿500,000 freelance income from a US client in October 2024. If you bring that money to Thailand via Wise in December 2024, it's taxable in Thailand in 2024 (not 2025).
Before January 2024, you could earn money offshore, wait a year, then remit it to Thailand tax-free. That strategy no longer works for new earnings.
Pension Income
Pension income is complex because of Double Taxation Agreements (DTAs). Under most DTAs, pension income paid by a foreign government is taxable only in the country that's paying the pension. However, you need to check your specific DTA — don't assume. A tax adviser can verify this for you in about an hour.
What's NOT Typically Taxable
- Capital gains from shares (except Thai company shares in some cases)
- Inheritance (no Thai inheritance tax)
- Gifts under ฿10M to non-relatives, ฿20M to relatives (amounts above these thresholds are taxable from 2016 rule changes)
Thai Income Tax Rates 2026
Thailand has a progressive tax system. The rate depends on your total taxable income after deductions:
| Taxable Income (THB) | Tax Rate |
|---|---|
| 0 – 150,000 | 0% (no tax) |
| 150,001 – 300,000 | 5% |
| 300,001 – 500,000 | 10% |
| 500,001 – 750,000 | 15% |
| 750,001 – 1,000,000 | 20% |
| 1,000,001 – 2,000,000 | 25% |
| 2,000,001 – 5,000,000 | 30% |
| 5,000,001+ | 35% |
Important: These rates apply to your income after deductions. Your actual tax bill is much lower than these percentages suggest because you get personal allowances and deductions first.
Personal Deductions & Allowances You Can Claim
Before you pay tax on your income, you can deduct these allowances and expenses:
- Personal allowance: ฿60,000
- Spouse allowance: ฿60,000
- Child allowance: ฿30,000 per child
- Employment income deduction: 50% of employment income (max ฿100,000)
- Social Security contributions: Fully deductible
- Life insurance premiums: Up to ฿100,000 per year
- LTF/RMF funds: Thai mutual funds (tax deductible up to annual limits)
Example: You earned ฿600,000 in Thailand as an expat working for a Thai company. Your deductions: ฿60,000 (personal) + ฿100,000 (50% employment, capped) = ฿160,000. Your taxable income is ฿440,000. At 10% rate on the band from 300k–500k, you owe about ฿14,000–15,000, not ฿60,000.
Double Taxation Agreements (DTAs)
Thailand has DTAs with 61 countries, including:
UK, USA, Australia, Germany, France, Canada, Netherlands, Spain, Italy, Sweden, Belgium, Denmark, and most EU nations.
How a DTA Works
A DTA prevents you from being taxed twice on the same income. Generally, it specifies which country has the primary right to tax different types of income:
- Employment income: Usually taxed in the country where the work is performed.
- Business income: Usually taxed where the business operates.
- Pension income: Usually taxed in the country paying the pension.
- Investment income: Usually taxed in the country of the investor's residence.
Thailand can still tax income earned in Thailand, even with a DTA. The DTA just prevents double taxation on the same income.
LTR Visa Tax Concessions
Thailand introduced the Long-Term Resident (LTR) visa in 2023. Some categories have special tax benefits:
LTR Wealthy Global & LTR Wealthy Pensioner
If you qualify under these categories, you get a flat 17% tax rate on your qualifying income — much lower than the normal progressive rates (which can hit 35%). This is a major benefit if you have significant foreign income.
LTR Work-from-Thailand Professional
This is the game-changer for remote workers. Foreign income earned outside Thailand is NOT taxable in Thailand for LTR Work-from-Thailand Professional holders. This was formally ruled by the Thai Revenue Department in 2023 and confirmed under the new 2024 rules.
Example: You're a US-based freelancer with LTR Work-from-Thailand Professional visa. You earn ฿2 million per year from US clients and bring it to Thailand via Wise. You owe no Thai income tax on that income.
This is a major advantage if you're a digital nomad or remote worker. The income is not even counted as Thai income.
Transferring Foreign Income to Thailand (Wise & Other Platforms)
Using Wise, TransferWise, or similar services to move money to Thailand counts as a remittance under Thai tax law. If that money was earned in 2024 and you bring it into Thailand in 2024, it's subject to the 2024 foreign income rule.
Do I Have to Declare It?
If the income is taxable (meets the remittance test above), yes — it should be declared on your Thai tax return.
The Thai Revenue Department has access to banking data, and Wise/TransferWise transactions are visible to Thai banks. Large, regular transfers into Thailand will eventually get attention.
What If I Don't Declare It?
Tax evasion in Thailand carries serious penalties: fines of 5x the underpaid tax amount, plus potential imprisonment for repeat offences. The enforcement is increasing, especially for expats with large transfers.
If you're unsure whether your specific transfer is taxable, ask a tax professional. It's worth ฿5,000–฿10,000 for a quick consultation.
Practical Steps to Take Now
1. Get a TIN (Taxpayer Identification Number)
You'll need a Thai TIN (เลขประจำตัวประชาชน) to file taxes and do formal financial transactions. Get this from the Phuket Revenue Department on Narisara Road, or apply online via rd.go.th.
2. Understand Your Tax Status
Are you a Thai tax resident? How many days did you spend in Thailand last year? This is your starting point. If you're on a long-term visa (O, O-A, O-X, LTR), you're almost certainly resident.
3. Document Your Income Sources
Keep records of:
- What income you earned and where (Thailand or foreign)
- When you earned it (which tax year)
- When you brought it into Thailand (remittance date)
- Evidence of the transfer (Wise receipt, bank statement)
4. Consider Your DTA & Specific Situation
If you have offshore income and are Thai resident, get a DTA analysis. If you have a pension, verify how it's taxed under your country's DTA with Thailand. If you hold an LTR visa, understand which category you qualify for and what tax benefits apply.
5. Use a Local English-Speaking Accountant (If Complex)
If your situation is straightforward (local employment only), you can file yourself. If you have offshore income, pension, rental properties, or business, use a professional. Phuket has several reputable firms:
- Lorenz & Partners: English-speaking expat tax specialists
- Sunbelt Asia: Large international firm with Phuket office
- Local accountants: Chao Fa Road area has several smaller firms at lower cost
Expect to pay ฿10,000–฿30,000 per year for professional tax preparation if your situation is moderately complex.
6. File Your Return (Deadline: March 31)
If you earned Thai-taxable income, file Form PND 91 (personal income tax return) at the Phuket Revenue Department or online at rd.go.th. Do not miss the March 31 deadline — the penalties compound.
Insider Tips from 6 Years in Phuket
The new foreign income remittance rules are still being interpreted inconsistently across Thailand's Revenue Department offices. Some offices are stricter, some more lenient. If you have significant offshore income, get a professional DTA and remittance analysis. It's worth the ฿30,000 to be certain of your position.
Many expats on Non-OA (retirement visa) have pension income from their home country. Most DTAs say pension income is taxed only in the source country. But verify your specific DTA — don't assume. A quick call to a tax adviser can confirm this for you.
When you bring money into Thailand (via Wise or bank transfer), keep the receipt and date it clearly. If audited, you'll need to prove when the income was earned and when it was remitted. This is your evidence for the 2024 rule.
If you're a remote worker or digital nomad earning foreign income, the LTR Work-from-Thailand Professional visa is a legal and legitimate way to avoid Thai income tax on your foreign earnings. It's being used increasingly by expat professionals. Check if you qualify.
Frequently Asked Questions
It depends on your tax residency and income sources. If you spend 180+ days in Thailand in a calendar year (tax residency), you must pay Thai income tax on income earned in Thailand and foreign income remitted to Thailand in the same year it was earned. However, DTAs may exempt certain types of income (like pension or foreign employment income). Check your specific situation with a tax professional.
The biggest change: Thailand now taxes foreign income remitted to Thailand in the same year it was earned. Previously, you could earn money offshore, wait a year, then bring it to Thailand tax-free. That planning strategy is no longer valid for income earned after January 2024. This is the most significant change for expats with offshore income.
Using Wise counts as a remittance under Thai law. If the money was earned in 2024 and you remit it to Thailand in 2024, it's subject to the 2024 foreign income tax rule (if you're Thai tax resident). However, if the income is exempt under a DTA (like pension income or foreign employment), or if you hold an LTR Work-from-Thailand Professional visa, it may not be taxable. Always verify with a professional.
It depends on the LTR category. LTR Wealthy Global and Wealthy Pensioner get a flat 17% tax rate on qualifying income (lower than normal rates). LTR Work-from-Thailand Professional: foreign income earned outside Thailand is NOT taxable. LTR Skilled Professional: standard tax rules apply. Check your specific LTR category for details.
File at the Phuket Revenue Department (สรรพากร) on Narisara Road, Phuket City. Or file online at rd.go.th. Form PND 91 is the personal income tax return. Deadline is March 31 of the following year. Late filing incurs a 1.5% per month fine plus a ฿2,000 penalty.
