Taxation is a system of raising money to support the government on financial matters. All governments require payments of taxes from people or any legal entity. These taxes are used by government to pay public employees, to build government infrastructures, public schools and hospitals, to provide food and medical care to the poor and elderly, and for other government purposes. It is true that tax is very important because without these taxes to support its activities, a government could not exist.

Taxation is the main source of government’s revenue. A large part of tax collection comes from three main agencies under the Ministry of Finance. These are the Revenue Department, the Excise Department, and the Customs Department – which collectively account for about 85-90% of the government’s revenue. The Revenue Department itself collects more than half of the total tax collection. Aside from collecting taxes, the Revenue Department is also responsible for ensuring that the administration of the tax collection is carried out in accordance with the government’s policies.

Thailand has many kinds of business identities. The tax rates and tax benefits of an individual or entity are affected by the type of its business.

An overview of Tax in the Kingdom of Thailand:

  • Personal Income Tax Personal Income Tax (PIT) is a direct tax levied on income of a person. A person means an individual, an ordinary partnership, a non-juristic body of person, a deceased person and an undivided estate. In general, a person liable to PIT has to compute his tax liability, file tax return and pay tax, if any, accordingly on a calendar year basis. Liability to tax depends on the concept of residence, and there is a liability to income tax if an individual is present in Thailand for at least 180 days or more in a tax year. Individuals and ordinary partnerships are liable to pay personal income tax in graduated rate bands of 5%-37% of net income. Tax is due on all forms of income earned in Thailand. The income liable to tax is income from all sources, less allowable expenditure and personal allowances.
  • Corporate Income Tax Corporate Income Tax (CIT) is a direct tax levied on a juristic company or partnership which is established under Thai or foreign law and carries on business in Thailand or derive certain types of income from Thailand. Corporate income tax is payable by companies and registered ordinary or limited partnerships. It is imposed on the net profits of a business during a tax year, after deduction of permitted depreciation and allowable expenditure. Tax is payable on the net profits arising from a business carried on. Foreign companies or partnerships are liable to pay tax on income originating in Thailand. The corporate tax rate is 30% of net income. The tax is paid in two stages. A company must file interim accounts and an interim tax return within two months of the end of the first six months of its accounting period and pay 50% of the tax estimated to be due. The final accounts and the year-end tax return must be filed within 150 days of the close of the accounting period and the balance of the tax paid, taking into account the interim payment made halfway through the accounting year.
  • Value Added Tax (“VAT”) Value Added Tax (VAT) has been implemented in Thailand since 1992 replacing Business Tax (BT). VAT is an indirect tax imposed on the value added of each stage of production and distribution. VAT is payable on the provision of taxable services by an entity registered for VAT. The Thailand VAT system is very similar to that in the United Kingdom. The main differences are: (i) the Thailand VAT rate is a flat rate of 10%, but temporarily reduced to 7% at present; and (ii) VAT returns are filed and the VAT due is paid monthly, within the 15th day of the month following the month of assessment.
  • Withholding Tax Certain types of income paid to companies are subject to withholding tax at source. The withholding tax rates depend on the types of income and the tax status of the recipient. The payer of income is required to file the return (Form CIT 53) and submit the amount of tax withheld to the District Revenue Offices within seven days of the following month in which the payment is made. The tax withheld will be credited against final tax liability of the taxpayer. The following are the withholding tax rates on some important types of income Withholding personal income tax must be deducted from an employee’s wages paid by his employer and paid to the Revenue Department on a monthly basis. Credit is given against the employee’s annual tax bill for any tax earlier withheld and paid. There are many other occasions when liability to withhold and pay tax arises, for example, on the payment of interest, rent or service fees. When a Thai company pays an invoice for services to another Thai company, 3% of the invoice amount is deducted and paid to the Revenue Department as withholding tax. The issuer of the invoice then has a tax credit for this amount, which he can utilize in his own tax return. International withholding taxes can also arise (see below).
  • Specific Business Tax (“SBT”) Specific Business Tax (SBT) is another kind of indirect tax introduced in 1992 to replace Business Tax. Certain businesses that are excluded from VAT will instead be subject to SBT. Certain types of business, including banking and pawn broking, are not subject to value added tax, but are subject to SBT. SBT also arises on the sale of land.
  • Stamp Duty Stamp duties are taxed on instruments and not on transactions or persons. For the purposes of stamp duty, an instrument is defined as any document chargeable with duty under the Revenue Code. The stamp duties rules are contained in Chapter VI of Title II of the Revenue Code. These explanations of different taxes are adapted from the Revenue Department of Thailand. Tax computation and other related responsibilities are very complicated especially when you are not familiar with the taxation system.

Q3: What are the government expected tax amount of dormant company I have to take in consideration for one year?

Panwa: Taxation of dormant company base on kind of related tax below; a. Corporate income tax (CIT), imposed base on “net profit” below is tax rate for year 2017 as below:

Net Profit Incentive for SME Capital not exceeding  Baht 5 million for year 2017 Ordinary company Capital exceeding  Baht 5 million for year 2017
0 – 300,000 0% 20%
300,001 – 3,000,000 15% 20%
Over 3,000,000 20% 20%

Normally, net profit will be calculated by = Income – Expenditure, for this should concentrate on kind of income as below situation:

  • You put capital fund into bank( such as saving account), this kind of income is “Interest from Bank”
  • You do not put that capital fund into bank that mean still keep in your personal bank, that fund must be recorded as “Loan to director”, this kind of income is “Interest” form its loan. Applicable interest rate for this borrowing is 4% per annum.

Example; Case study:  Capital is Baht 10 million, Expenditure Baht 20,000 for 1 year period, tax amount will be paid is Baht

(4%10,000,000) – 20,000 = Net profit = 380,000 Baht, CIT – Tax amount = 20%380,000 = Baht 76,000 per year), applicable tax rate is 20% **SBT – Tax amount = 3.3% of 400,000 = Baht 13,200 per year, will be paid when settle interest of loan.

  • 3. We recommends you set up company with capital of Baht 1 million and paid up only 25% of registered capital. In the same case study, tax amount for capital Baht 1 million with paid up capital 25% is CIT = Baht 0.00 per year. **SBT = Baht 330 per year.

b. Half year tax, except for the first year, but for the second year and onwards will be paid at least 50% of CIT and can use its tax as credit amount for CIT’s calculation at ending period.

c. Monthly withholding tax, will withhold and be paid within 7th day of the following month. Normally, dormant company no business activity will no withholding tax amount.

e. **Special Business Tax (SBT), base on “Interest Income” from “Loan to director” by applicable tax rate is 3.3% per annum.

Q4: The company is carrying on hotel business by construction of building in progress. The first building was constructed in year 2003 whereas the company constructed only partial around 1 out of 3 of the total project. The company opened the hotel from the partially constructed building to serve the clients while still continues the construction of the remaining building and planned to finish in year 2004. Initially for the first plan, they planned to operate the hotel on 2006. The company declared the income of year 2003 and 2004 in the PP.30 form as income of the complete project. For the partial completeness of hotel where they generate the income, the company has cost also. This cost is depreciation of the building including furnishing. From this, the company has certain inquiries:

  1. Does the company can be able to calculate the depreciation of building in progress for the partial construction to be the expenditure of year 2003 or not? In case that can be able, the company has right to calculate depreciation of the building from what value?
  2. The company will have more income in year 2005 due to partial construction of work in progress of the 2nd part has completed and can open later than year 2004. The company can calculate depreciation of building same as item no. 1 or not?
  3. In case of recording as referred to item 1 and find mistake, how does the company adjust to correct the mistake due to the company carry on hotel business which is different with other businesses?


In the case of item 1 and item 2 above, the company can use building in progress which is partially completed around 1 of 3 of all projects which is already opened for service in year 2004 which affects to the company to generate income from service, therefore, the company can calculate ratio of the complete building clearly under actual usage in compliance with the Generally Accepted Accounting Principles (GAAP). The company is eligible to deduct depreciation of hotel partial building value under the ratio of the building value by using the start of depreciation from the first day that the building was used.
In the case of item 3, the recording of deduction of partial depreciation, the company is eligible to record in compliance with GAAP. In case the company did mistake in recording, the company is eligible to adjust its recording.

Q5: I was a resident for tax purposes and filed a tax return in 2009. In 2010 I stayed in Thailand over 180 days but did not bring any part of my income into the country, so I think I need to file a nil tax return.

Panwa: There’s no need to file your personal income tax in Thailand for year 2010 due to did not bring any part of your income into Thailand and also you earn income in Thailand less than Baht 50,000 per annum for salary and less than Baht 30,00 per annum for other.
