Tax Registration and Compliance for a Thai Company

A practical guide for foreign founders on tax registration and ongoing compliance obligations for a Thai company, covering VAT, corporate income tax, withholding tax, and reporting requirements.

Introduction

Setting up a company in Thailand involves several tax registration and compliance steps that foreign founders must understand. This article outlines the key requirements for a Thai limited company, focusing on tax registration, ongoing filings, and practical considerations. It is intended for foreign founders establishing a business in Thailand and assumes a standard Thai private limited company structure.

Tax Registration Upon Incorporation

After a Thai company is incorporated, it must register for taxes with the Revenue Department and other relevant authorities. The main registrations are:

• Corporate Income Tax (CIT) registration: A newly incorporated company must obtain a Tax Identification Number (TIN) and register for CIT within 60 days of incorporation. This is typically done at the Revenue Department office where the company is located.
• Value Added Tax (VAT) registration: VAT registration is mandatory if annual turnover exceeds THB 1.8 million. Companies with lower turnover may register voluntarily. VAT registration should be completed before commencing business activities that generate VATable supplies. The VAT certificate and tax invoice book are issued upon registration.
• Withholding Tax (WHT) registration: Companies that pay assessable income to individuals or juristic persons must register as withholding agents. This is usually done together with CIT registration.
• Social Security Fund registration: Employers with at least one employee must register with the Social Security Office within 30 days of hiring.

Ongoing Tax Compliance

Corporate Income Tax (CIT)

Thai companies are subject to CIT on worldwide net profits. The standard CIT rate is 20%. CIT returns are filed semi-annually:

• PND.51: Annual CIT return, due within 150 days of the fiscal year-end.
• PND.50: Half-year CIT return, due within two months after the end of the first six months of the fiscal year.

Companies must also prepare and submit financial statements audited by a certified public accountant in Thailand.

Value Added Tax (VAT)

VAT-registered companies must file VAT returns (PND.30) monthly, due by the 15th of the following month. VAT is charged at 7% on most goods and services. Input VAT can be credited against output VAT, with certain restrictions. Late filing and payment incur surcharges and penalties.

Withholding Tax (WHT)

Companies must withhold tax on certain payments, such as salaries, professional fees, rent, and service fees. The withheld tax must be remitted to the Revenue Department using forms PND.1 (for individuals), PND.53 (for companies), and PND.54 (for certain payments abroad). Filing and payment are due by the 7th of the following month (or the 15th for PND.54).

Other Taxes and Contributions

• Personal Income Tax (PIT): Employers must withhold PIT from employees’ salaries and remit it monthly.
• Social Security Contributions: Employers and employees each contribute 5% of wages to the Social Security Fund, capped at THB 750 per month per person (as of 2023). Contributions are due by the 15th of the following month.
• Stamp Duty: Certain documents, such as leases and loan agreements, are subject to stamp duty.
• Specific Business Tax (SBT): Applicable to certain businesses like banking and insurance, instead of VAT.

Electronic Filing and Record Keeping

Thailand has increasingly moved towards electronic filing. Many tax returns can be submitted online via the Revenue Department’s e-Filing system. Companies must maintain proper accounting records and retain them for at least five years. Records must be in Thai or English, and accounting must follow Thai Financial Reporting Standards (TFRS).

Common Pitfalls for Foreign Founders

• Missing VAT registration threshold: Even if turnover is below THB 1.8 million, voluntary VAT registration may be beneficial for claiming input VAT, but it adds compliance burden.
• Incorrect WHT treatment: Payments to foreign entities may be subject to WHT and require careful consideration of double tax treaties.
• Late filings: Penalties for late filing and payment can be significant, including surcharges of 1.5% per month and fines.
• Transfer pricing: Related-party transactions must be at arm’s length, and documentation may be required.

Conclusion

Tax registration and compliance for a Thai company require timely action and ongoing attention. Foreign founders should engage local tax advisors and accountants to ensure compliance with Thai tax laws and to navigate the specific requirements of their business. Proper planning from the outset can help avoid penalties and support smooth operations.
