Tax Identification Number (TIN) in Thailand
Every company and most individuals earning taxable income in Thailand need a Tax Identification Number from the Revenue Department. At Thai Visa Centre in Bangkok, we help foreign directors and employees understand when a TIN is required for banking, payroll, and immigration-related employer compliance.
Company TIN and personal TIN are different numbers. A foreign director needs both if drawing salary and signing as company representative. Read our corporate tax guide for filing obligations.

What is a Thai TIN?
A Tax Identification Number is a 13-digit identifier issued by the Revenue Department for tax administration. Without a TIN, you cannot complete many official transactions including VAT registration and payroll withholding.
| TIN type | Issued to |
|---|---|
| Corporate TIN | Registered companies, partnerships, and branch offices |
| Personal TIN | Individuals, Thai nationals and foreigners with tax obligations |
Corporate TIN registration
New limited companies should verify TIN activation before first invoice or hire. Corporate TIN is required for VAT registration, withholding tax filing, corporate bank accounts, and work permit employer verification.
DBD company registration
Obtain company registration certificate from the Department of Business Development.
Revenue Department notification
Corporate TIN often links automatically via DBD data after registration.
Confirm activation
Verify TIN appears on tax documents and VAT certificate before first invoice or hire.
Personal TIN for foreigners
Foreign individuals need a personal TIN when employed, filing personal income tax, or receiving Thai-source income. Apply at the Area Revenue Office for your address or employer.

Long-stay and lifestyle context
Many readers use this page while scouting Thailand for relocation, visa runs, or extended holidays. Pair hotel planning with immigration status that matches how long you actually stay. Tourist exemption and short tourist visas are for trips, not for building a life here.
See our Thailand lifestyle guide for visa paths, city choices, TM30, 90-day reporting, and compliance habits that keep long-stay holders out of trouble at immigration.
Who needs a TIN
Tax identification numbers matter for property transfers, employment, company directors, and some visa financial declarations. Long-stay residents crossing tax-residency thresholds need coordinated advice.
Visa overlap
Marriage and retirement visa renewals may ask for tax records or bank history. Obtain TIN and filing clarity before extension season if Revenue Department correspondence is likely.
Property and rent
Landlords and condo owners declaring rental income register with Revenue Department. TIN links personal and corporate obligations. Do not assume tourist status avoids all filing duties.
Professional help
TVC coordinates immigration; licensed accountants handle TIN registration and returns. Read the lifestyle guide for tax-residency context alongside visa planning.
