    Singapore-Thailand Relationship Over the Years

    Singapore and Thailand have had a long-standing and significant economic tie since the beginning of the nineteenth century. Thailand was among the first nations to develop diplomatic relations with Singapore, and since that time, their relationship has been continuously developed and maintained. One of Thailand’s biggest international investors is Singapore. With overall trade of approximately $17.5 billion in Singapore in 2022, Thailand is the nation’s ninth-largest trading partner.

    By creating a number of cooperation programs like the Singapore-Thailand Enhanced Economic Relationship (STEER) and the Thailand-Singapore Civil Service Exchange Programme (CSEP), the Singaporean and Thailand governments have further strengthened broad institutional ties. Both initiatives seek to improve cross-border connections between citizens of the two nations. Through increased collaboration in the business, investment, and tourist sectors, bilateral ties are being improved between the nations.

    Thailand-Singapore DTAA

    An agreement was reached between Thailand and Singapore on June 11th, 2015, to eliminate double taxation and fiscal evasion regarding income taxes. This was the new Thailand and Singapore double taxation avoidance agreement which became effective on January 1, 2017.

    The existing DTAA between Thailand and Singapore, ratified on September 15, 1975, has been in effect for over 30 years. In addition to other modifications, the new Thailand-Singapore DTAA extends the time frame for evaluating the presence of a permanent establishment (PE) and reduces the withholding tax rates for profits, interests, as well as royalties.

    The Singapore and Thailand DTAA will be applicable to individuals who are residents of either one or both of the contracting nations. The Agreement guarantees that investors working in both jurisdictions would receive favorable tax treatment and improves the flow of investments and trade within the two nations. Many firms find it particularly advantageous to establish their management and other back-office activities in Singapore while continuing to run their revenue-generating activities in Thailand.

    What does Tax Residency mean?

    A person, business, or other legal entity is considered a “resident of a country” if it is liable for taxation there as per the regulations of that nation because of its domicile, residency, location of incorporation, or any other comparable factor.

    In the event that a person can be considered to be a resident of both Singapore and Thailand, the significant considerations that establish the taxpayer’s residency status are listed below in decreasing order of importance:

    • The nation in which the person resides permanently.
    • The nation where the person has his or her core interests with regard to their personal and professional relationships.
    • A person shall be regarded as a resident of the nation of which they are a national regardless of whether they have their regular residence in one of the two nations or neither of them.

    The competent authorities of the two nations will decide the issue of residency by mutual agreement if none of the aforementioned guidelines apply.

    Kinds of income included under the Singapore and Thailand DTAA

    The Thailand-Singapore DTAA specifies the nation in which a Singaporean or Thai resident’s earnings are going to be taxed. This is significant because, in the absence of any explicit mention of tax rates in the DTAA between Thailand and Singapore, the rate of taxation that applies to the taxpayer’s revenue will automatically be determined by the nation in which the earnings are taxable.  The regulations of the Thailand and Singapore double taxation avoidance agreement states that the agreement covers a variety of income categories, including:

    Business profits Are taxed in the nation in which the business operates and is governed
    Permanent Establishment (PE) Profits Are taxed in the nation in which the Permanent Establishment is located and does its operations, but only on the value that is specifically due to that PE.
    Earnings generated from shipping and air transport The earnings generated by an organization of a contractual nation are required to pay taxes on any income or profits earned from operating airplanes in international traffic in that contractual nation. A corporation of a contracting nation may have its revenue from operating ships in foreign trade taxed in another Contracting nation, but that other nation’s tax will be decreased by 50% of those earnings.
    Dividends A corporation that is a resident of one Contracting State that pays dividends to a resident of another Contracting State can be subject to taxation in that other State. Nevertheless, they can be liable to taxation in the Contracting State where the organization that is disbursing the dividends is based. Yet the tax so levied may not be higher than 10% of the total value of the dividends if the beneficiary of the dividends is a resident of the other Contracting State.
    Royalties Typically, royalties are taxed in the nation where the beneficiary resides. The DTAA allows for the taxation of royalties in the contractual nation from which they originate. If the receiver is a citizen of the other contractual nation, the tax thus assessed cannot surpass:
    • 5% of any royalties that are granted for using a work’s copyright, whether it be for creative, literary, or scientific purposes.
    • 8% for using a patent, trademark, design, model, plan, secret formula, method, or piece of machinery used in industry, commerce, or science.
    • 10% of the overall value of the royalties in any other circumstances.
    Interests Interest that is generated in one contractual nation and given to a citizen of another contractual nation could be subject to taxation in that other nation. Although such interest might additionally be taxed in the participating nation where it originates and in accordance with its rules, if the beneficial proprietor of the interest is a resident of the other participating nation, the tax thus imposed cannot be greater than:
    • 10% of the interest’s aggregate value if any financial organization or insurance provider owns the interest in its entirety.
    • 10% of the overall interest owed shall be paid if interest has been made on debt associated with the trade of any products, services, or equipment on credit.
    • In every other circumstance, 15% of the interest’s aggregate value.
    Capital gains Are taxable in the nation in which the property is situated.
    Revenue generated from independent personal services Such income is taxed in the beneficiary’s nation of residence unless the receiver has a fixed base frequently accessible in another nation for the purposes of carrying out his or her operations, or unless the recipient stays in the other nation for over 183 days in any 12-month time frame.
    Revenue generated from dependent personal services Taxed in the nation of residence of the receiver, unless the work is performed in another nation.
    Directors’ fees Taxable in the nation where the corporation (paying the directors’ salaries) is located.
    Earnings of artists and sports persons Taxable in the nation where the activity is carried out.
    Pensions Taxes are levied in the nation where the receiver resides.
    Payments received by students When receiving training or education in another contracting state while temporarily residing there only for that reason, students and trainees who were residents of one contracting state immediately prior to their visit are exempt from paying taxes in that state.
