A Common Misconception
Many expats assume that holding a retirement visa — the Non-Immigrant OA — gives them some form of special tax status in Thailand. It does not.
Your visa type has no bearing on your tax obligations. Tax residency in Thailand is determined solely by how many days you spend in the country each year.

The Non-Immigrant OA Visa (Retirement Visa)
The Non-OA visa is Thailand's standard long-term visa for retirees aged 50 and over. It is issued for one year and can be renewed annually. Requirements include:
- Age 50 or over
- Financial proof: 800,000 THB in a Thai bank account, or 65,000 THB monthly income, or a combination
- Health insurance
- No criminal record
What the Non-OA Visa Does NOT Do
- Does not reduce your tax rate
- Does not exempt any income from Thai tax
- Does not change your tax residency status
- Does not waive any filing requirements

Tax Residency is About Days, Not Visa Type
If you hold a Non-OA visa and live in Thailand for 180 or more days in a calendar year, you are a Thai tax resident with full filing obligations. This is true regardless of whether you have a Non-OA, tourist visa, Elite visa, or any other status.
The 180-Day Rule in Practice
The 180 days are counted per calendar year (January 1 to December 31). They do not need to be consecutive. Most retirees living in Thailand full-time will comfortably exceed 180 days.
If you exceed 180 days:
- You are a Thai tax resident
- All Thai-sourced income is assessable
- Foreign income remitted to Thailand is assessable (since January 2024)
- You must file a PND.90 or PND.91 return if income exceeds filing thresholds
If you stay under 180 days:
- You are a non-resident
- Only Thai-sourced income is taxable
- Foreign income is not taxable in Thailand regardless of remittance
- Some retirees deliberately split time between Thailand and another country to remain non-resident

What Income Is Taxable for Non-OA Visa Holders?
Thai-Sourced Income (Always Taxable if Resident)
- Thai bank interest (though 15% withholding is often treated as final tax)
- Thai dividends (10% withholding, can be final)
- Rental income from Thai property
- Any employment or business income earned in Thailand
Foreign Income (Taxable Since 2024 if Remitted to Thailand)
- Overseas pension payments transferred to Thailand
- Overseas investment income transferred to Thailand
- Overseas property rental income transferred to Thailand
- Any other overseas income brought into Thailand by any means (wire transfer, ATM withdrawal, credit card usage)

The Financial Proof Requirement vs. Tax Obligations
Holding 800,000 THB in a Thai bank account (the common financial proof method for Non-OA renewal) means that money is in Thailand — but it only becomes assessable income if it was income remitted from overseas. Capital held offshore before you became a Thai resident is not income.
However, interest earned on that 800,000 THB account is assessable income in Thailand (subject to 15% withholding by the bank).

Filing Requirements for Non-OA Retirees
If you are a Thai tax resident (180+ days), you must file if assessable income exceeds:
| Situation | Filing Threshold |
|---|---|
| Pension/salary income only | 120,000 THB (single), 220,000 THB (married) |
| Income from investments, rental, or other sources | 60,000 THB (single), 120,000 THB (married) |
