  • Have Thai-sourced income within the filing period

Foreigners may also be eligible, subject to:

  • Holding a valid work permit and official income

Tourists and short-term visitors may qualify for a VAT refund if they:

  • Spend at least 2,000 THB at participating stores on a single day

Thailand Tax Filing & Refund Process

Filing Income Tax Returns (P.N.D. 90/91)

Start by collecting your documents before the tax filing deadline (typically March 31). Filing late can delay or void your refund. Use the Official e-Filing Portal for online submissions.

Key steps:

  • Complete Form P.N.D. 90 (mixed income) or P.N.D. 91 (single income).
  • Attach required documents:
    • Withholding tax certificate
    • Thai ID card or passport (for foreigners)
    • Proof of tax-deductible expenses (receipts, insurance, mortgage)
    • Bank account details for refunds
    • Work permit (foreigners only)
  • Submit through the e-Filing portal or visit your local Revenue Department office.

Refunds are usually processed within 30-90 days but may take longer for complex or incomplete filings. Failing to submit correct bank details or missing documents can result in processing delays or denial.

Appealing Rejected Refunds & Corrections

If your refund is denied or delayed, you can appeal within 30 days by:

  • Contacting the Revenue Department for clarification on missing or incorrect items.
  • Submitting additional supporting documents or corrected forms as requested.
  • Amending your tax return through the e-Filing portal if you discover mistakes yourself.

Common issues include missing documents, mismatched bank details, or unclear deductions.

Accurate, timely submissions help you avoid delays or appeals. Efficient documentation management is the foundation of a successful Thailand Tax Filing experience.

Maximizing Thai Tax Deductions & Allowances

Guide to Tax Deductions in Thailand (2025)

Claiming all eligible deductions under Thailand Tax Filing can reduce your tax liability and increase potential refunds.

Key deductible categories for 2025 include:

  • Personal allowances
  • Family and dependent care (including elderly parent support)
  • Mortgage interest payments
  • Education expenses for children
  • Life and health insurance premiums
  • Charitable donations to approved organizations
  • Investment in retirement funds (RMF and SSF)

A commonly missed opportunity involves deductions for direct parent care or education-related investments, saving some taxpayers thousands of THB each year.

Deductions vs. Exemptions Explained

Tax deductions lower your taxable income, while exemptions remove certain parts from taxation entirely.

For example:

  • If your gross income is 1,000,000 THB, and you deduct 100,000 THB for mortgage payments, only 900,000 THB is taxed.
  • If your income includes a tax-exempt severance of 150,000 THB, that amount is excluded before deductions are applied.

Claiming every eligible deduction or exemption can make a significant difference, each individual tax planning decision has both immediate and long-term benefits.
