Business Registration Complete? What Next?

Completing your business registration in Thailand marks an exciting new chapter — and it’s just the beginning. At Attori Law, we support businesses beyond registration, helping lay a strong legal and operational foundation for long-term success.

Whether you’re a local entrepreneur or a foreign investor, here’s what you need to know after registering your Thai company.

After your business registration is complete, setting up a company bank account is a priority. This is essential for managing transactions, paying suppliers, and keeping your company finances in order. We’ll help you understand the documentation banks require. Thai banks typically require company documents, director ID, and a company seal. Attori Law can guide you through the process smoothly.

Once your business is active, there are several important tax obligations to keep in mind. While your company receives its Tax ID automatically upon registration, you may still need to take additional steps depending on your business activity.

If your annual revenue exceeds 1.8 million THB, or if you’re engaged in certain types of business (such as trading or services), you’ll be required to register for Value Added Tax (VAT). 

In addition, all companies in Thailand must submit monthly tax filings, which may include:

• Withholding tax (WHT) on salaries, contractor payments, and rent

• Social security contributions for any employees

• VAT filings, if registered

• Corporate income tax prepayments, depending on your earnings

Staying compliant with these requirements is crucial to avoid penalties and maintain smooth business operations. Attori Law offers ongoing accounting and tax support to ensure you’re covered every step of the way.

If you’re hiring employees, you must register your company with the Social Security Office and begin making monthly contributions to the Social Security Fund. This is a legal requirement in Thailand and applies as soon as your business employs at least one person.

Both the employer and employee are required to contribute to the fund, with each contributing 5% of the employee’s monthly salary, up to a maximum salary base of 15,000 THB. These contributions help cover benefits such as healthcare, unemployment, maternity, and pensions.

To remain compliant, it’s essential to have a proper payroll system in place that accounts for:

• Accurate salary calculations

• Withholding tax deductions

• Social security contributions

• Timely payslip issuance

• Submission of monthly reports to the Social Security Office and Revenue Department

Foreign directors and employees will need valid non-immigrant visas and work permits to legally live and work in Thailand. This process involves multiple steps and coordination with both the Thai Immigration Bureau and the Department of Employment.

It’s important to note that while owning a company in Thailand does not require a work permit, you do need one if you plan to be actively involved in the business — such as managing operations, signing contracts, or dealing with clients.

Depending on your business activity, additional licenses or permits may be required after company registration. These licenses are industry-specific and are issued by different government authorities. Operating without the proper licenses can result in fines, legal issues, or business closure.

Here are some common examples:

• Restaurant or café – Requires a food license, and if alcohol is served, an alcohol license from the Excise Department

• Import/export business – Requires registration with the Thai Customs Department and possibly FDA clearance for certain products

• Hotel or guesthouse – Requires a hotel license and compliance with zoning and safety regulations

• Education or training services – May require a license from the Ministry of Education

• Tour companies – Require a Tourism Business License issued by the Tourism Authority of Thailand (TAT)

The application process can vary greatly in complexity and duration, often involving site inspections, supporting documents, and coordination with multiple government departments.

A legally sound foundation includes more than just company registration — it means having the right contracts and internal policies in place from the start. This includes clear, enforceable agreements with clients, vendors, and employees, as well as internal documents such as employee handbooks, confidentiality agreements, and data protection policies.

Not all necessary policies will be obvious at first. As your business grows, so do your legal obligations and potential risks. For example, you may need to implement:

• Non-disclosure agreements (NDAs) to protect sensitive information

• Employment contracts tailored to different roles and responsibilities

• IT and data security policies to comply with Thailand’s Personal Data Protection Act (PDPA)

• Workplace conduct guidelines to ensure consistency and compliance with labor laws

Establishing a strong legal framework is an ongoing process, not a one-time task. Policies should be reviewed and updated regularly to reflect changes in the law, your operations, and your team.

Starting or growing a business in Thailand can seem complicated, but it doesn’t have to be. We’re here to guide you every step of the way and make sure your legal and regulatory foundations are solid — so you can focus on what matters most: your business.
