Thailand: Double Jeopardy Double Taxation






It is the beginning of the new year and anxiety among my clients are high. Clients who have businesses in multiple countries have called me in fear of the tax man. Their fears are based on the unknown. They don’t understand the tax laws and fear the confiscatory powers of the revenue department for errors in their filings.

For foreign nationals in living in Thailand, Thai tax laws and forms are written in a language that they cannot read. There are Thai accountants who can assist them with Thai tax filings. However, this issue is not readily solved when individuals who have business dealings in multiple countries.

For individuals and companiesthat operate in multiple countries, double taxation can place them in financial peril. Juridical double taxation is when multiple jurisdictions tax the same income, assets, or financial transaction.

In most countries, a company is taxed at the place where they are registered or have their headquarters and also any worldwide income. So if a Thai company had a branch in a foreign country, the company could possibly have to pay tax on income in the foreign country and on the same income in Thailand.

This will mean that they are taxed twice on the same income. Unless there is an agreement between the two countries, this will be a large financial impediment to the Thai company.

With increased globalization, this issue has become a more common problem. In order to increase trade and to prevent their citizens from being unfairly punished for expanding their business, Thailand has entered into bilateral tax conventions with 60 countries. Tax treaties protect foreign citizens and companies from being taxed differently from local businesses.

Tax treaties also protect profits from being double taxed. There are multiple types of provisions that are negotiated by tax treaty countries but the tax treaties remove the uncertainty of taxation for international transactions.

In Thailand, there are many various methods of avoiding the double taxation.Acombination of these various methods can be implemented to provide taxpayers double tax relief, such as the Foreign Tax Credit, Exemption Method or the Deduction Method.

i. A Foreign Tax Credit is offered by income tax system to mitigate the potential for double taxation. The credit can be granted in those systems that taxes residents on income which have been taxed in another jurisdiction.Thisreducesthe amount of domestic taxes are due by the amount of the foreign tax as a credit of tax already paid.

So if a Thai company or individual paid taxes in a foreign country, they will be provided a tax credit for the amount of foreign taxes paidfor the same income up to the amount of taxes that they owe in Thailand.

ii. Exemption Method is usually happened when country of residence taxes its residents on their domestic-source income and provides an exemption to them from domestic taxes on their foreign-source income. Jurisdiction to tax rests exclusively with the country of source.

The United States allows its citizens who live abroad an exemption to exclude a certain amount of earned income from their annual tax filing. For the amount of earned income up to the exclusion amount, they are only liable to pay the foreign taxes.

iii. The Deduction Method allows its taxpayer in the country of resident to ask for deduction of taxes, which have been paid to a foreign government in respect of foreign source income. The deduction method is different from a Foreign Tax Credit in that a deduction reduces the taxpayer’s taxable income while a credit provides a full credit on the taxes that are owed.

Most local Thai accountants cannot handle tax issues that deal with transactions involving multiple jurisdictions. There are tax specialists who understand how to handle these issues. Government Revenue Departments have immense power and errors can lead to businesses being shut down. When deciding to enter into international business transactions, it is prudent to consult someone who understands the tax laws in both jurisdictions.
