Tax Planning

Tax Planning in Thailand

Tax planning is essential for business owners, particularly when establishing a business in Thailand. By effectively managing taxable fees, businesses can monitor and optimize their tax liabilities through strategic tax planning.

At Juslaws & Consult, we recognize that proper tax planning can result in significant financial benefits for our clients. Our top priority is to minimize the tax liability of an individual or a company by providing Thailand-specific tax planning advice and services.

Keeping clients informed about changes in Thailand's tax regulations is essential. Additionally, our advisors may review onshore and offshore structures, as well as relevant double taxation agreements, to optimize the tax position on cross-border transactions for clients engaging in international dealings.

Tax Documentation

Every company is obligated to submit various tax documents to the Revenue Department. If you lack expertise as a professional Thai accountant, it is advisable to engage someone proficient in managing the taxes and accounting affairs of your company. Common tax forms required for companies in Thailand include the following:

For the Social Security Office:

  • Form Kor.Tor.20
  • Form Kor.Kor.Tor. 26 Kor.

For the Revenue Department

  • Corporate Income Tax Return and Financial Statements (PND 50).
  • File form of foreign employees' income with form PND 1
  • Tax form PND 1 Kor.
  • Interim corporate income tax return (PND 51)

The tax forms mentioned above represent only the fundamental tax requirements that companies must submit annually and monthly to the Revenue Department and other relevant government departments in Thailand for taxation purposes. Therefore, it is recommended to engage a reputable and professional accounting firm to assist with tax matters if your company does not have an in-house corporate tax accountant.

Our Tax Experts

We offer comprehensive expertise and services to clients and companies regarding all local taxes in Thailand, including corporate income tax (for registered companies), sales tax, withholding tax, stamp duty, and customs duty. Our team provides strategic advice on tax planning strategies and can assist with various matters such as claiming tax refunds, appealing tax assessments, and preparing periodic tax filing documentation for submission to the tax authorities. Juslaws & Consult has a proven track record of representing clients' interests with Thai tax authorities in areas where tax regulations are ambiguous or unclear. Given that most commercial agreements are subject to various taxes, it's crucial for parties involved to understand the relevant taxes that may be imposed. We advise our clients on structuring commercial transactions optimally to minimize their tax exposure. Additionally, tax cases brought before Thai courts are typically evaluated based on economic reality rather than the contractual relationship stipulated in agreements, following the doctrine of "substance over form". Our Taxation department analyzes the economic realities underlying deals and drafts agreements that ensure tax burdens are minimized in commercial contract tax planning.

We also offer services and advice to individuals who are not business owners but are required to pay personal income tax and may need assistance with calculating, determining, and submitting personal income tax forms. If you're unsure about personal income tax rates in Thailand or need help distinguishing between taxable income and employment income, contact us today. One of our expert consultants will assist you with understanding taxable income and guide you through the process of calculating your personal income tax contribution.

International Tax Planning Services

Even for offshore or multinational international corporations based in Thailand, understanding tax matters and specific corporate tax and withholding tax laws is crucial. The tax implications in such situations can be complex, making it essential to consult with professionals who can provide guidance on taxation issues and help navigate tax benefits. Unsure about what needs to be submitted to the Revenue Department or whether your offshore company is subject to tax, let alone the applicable tax rate? Contact us today, and we'll guide you through the intricate network of tax implications in these situations. Thailand's progressive tax rates make it an attractive location to establish an offshore company.

What does an Average Taxpayer Need to Know

  • The general tax authority in Thailand is the Revenue Department.
  • The tax year in Thailand spans from January 1st to December 31st.
  • The usual tax return date for income tax and corporate income tax in Thailand is March 31st.
  • In Thailand, joint filing is the default tax filing method, and no extensions are granted for tax returns.

Both non-resident and resident individuals who earn income in Thailand are required to pay personal income tax. Residents are also obligated to pay income tax on business income earned overseas and self-employment earnings remitted in Thailand. An individual is classified as a "resident" if they have been in Thailand for 180 days or more during any calendar year.

When the Revenue Department suspects that an individual has understated their income, they may reassess their tax based on their net worth instead. This can be particularly disadvantageous for high net worth individuals, underscoring the importance of honesty in tax returns.

It remains the individual responsibility of the taxpayer to file their tax returns each year, including for international clients liable for taxation in Thailand. For more detailed information on various tax aspects such as capital gains tax, standard deductions (such as personal allowance), investment taxation, company taxes including dividends, taxpayer responsibilities, property taxes, legal issues related to missed tax payments, etc., please refer to our other pages on essential taxpayer information. We can also assist you in assessing your tax rate based on your income and tax withheld from corporate taxation. Additionally, if the Revenue Department requires audited financial statements, we can provide assistance with that as well.

Overall, tax planning plays a crucial role in your broader financial planning for a business, corporation, or firm. It's important to consider each employee in your planning process, and being prepared for annual tax payments in advance is advisable to avoid penalties incurred by late payments. Adequate preparation for taxation can be viewed as an investment in your company's future, and we take pride in assisting our clients in achieving this goal.

Even if you require assistance with specific elements of taxation, such as property taxes, dividends, transfer pricing, value-added tax on a cash basis, or employee considerations, feel free to contact Juslaws & Consult for a consultation today. We are here to help you navigate the complexities of taxation and provide tailored solutions to meet your needs.
