Employers are required to issue Withholding Tax Certificates to employees by 15th February each year or within 1 month of termination of employment

Personal Income Tax ReturnsAll individuals are required to file an annual personal income tax return by 31 March each year. Any  additional tax must be paid at the same time. In the event tax has been over-withheld a refund may be claimed.
Value Added TaxMost businesses are required to register for VAT, the exceptions being:
Those business operations subject to specific business tax; andExempt business such as agriculture, sale of newspapers, educational establishments, etc;Rates of VATThere are two rates of VAT as follows:

0% rate for export of goods and services; and10% standard rate (which has been temporarily reduced to 7%) for sales of goods and provision of  services in Thailand and import into Thailand. Liability to VATLiability to VAT for sale of goods arises at the time of delivery of goods unless transfer of ownership,  receipt of payment or issuance of a tax invoice occurs prior to delivery.

Liability to VAT for provision of services arises at the time the service fee is received, unless a tax invoice is issued earlier or the service is used before payment is made.
Tax InvoicesVAT operators are required to issue tax invoices to their customs and such tax invoices must be serially  numbered. The tax invoice must include the particulars and the information stipulated in the Revenue  Code.

Credit NotesWhere the value of the goods or services sold to a customer has to decrease, a credit note is issued to the customer. This credit note must also include the particulars and the information stipulated in the Revenue Code.

VAT ReturnsMonthly returns must be completed and filed by the 15th day of each month (in respect of the preceding  month’s VAT transactions). The net VAT amount is required to be paid to the Revenue Department at the same time, and is calculated as the amount of output VAT (VAT charged to customers) less input VAT (VAT incurred on goods and services purchased).

For imported goods, the VAT is collected by the Customs Department, which issues a tax receipt. This tax receipt then becomes input VAT and is claimed against output VAT in the monthly VAT returns.
Certain input VAT cannot be claimed as an offset against output VAT. These include input VAT on  entertainment expenses, input VAT on passenger vehicles, input VAT where a proper tax invoice is not available or where the tax invoice is incorrect or incomplete, and input VAT where a tax invoice has been issued by a person not authorised to do so.
If input VAT exceeds output VAT, the excess input VAT is carried forward and offset against future month’s VAT returns or an application can be made for a refund of the excess input VAT.

VAT RecordsInput and output VAT records must be maintained and these must detail all the VAT transactions occurring during the month. In addition, operators who carry out sale of goods are required to maintain a goods and raw materials record.
VAT on Imported ServicesFor payment of services provided by foreign companies not carrying on business in Thailand, such as  payments for management fees, royalties and technical service fees etc, the recipient of the services in Thailand is required to pay the VAT.

The VAT on the offshore payments is remitted to the Revenue Department by the 7th day of the following  month, and the receipt issued by the Revenue Department is treated as input VAT and claimed in the  monthly VAT return for the month that the VAT is paid.
Specific Business TaxCertain business transactions are subject to specific business tax (SBT) rather than VAT. Such business  transactions and their SBT rates are as follows:

Double Taxation AgreementsThailand has concluded 52 double taxation agreements in order to provide relief from international double taxation of income. A listing of the counties and territories and their effective dates is attached in Appendix I (see end of publication).
Transfer Pricing GuidelinesIn 2002, Thailand introduced Transfer Pricing (TP) guidelines to Revenue officers for their use when  examining pricing arrangements between related parties. The guidelines require the Revenue officers to be concerned with arrangements that don’t apply “market prices” between “related parties”.
The related party connection between two or more companies is determined according to:
Direct or indirect shareholding in one company by another; or
Common directors and/or management.
Under the guidelines, the Revenue Department officers are permitted to accept four kinds of pricing  methods by companies as follows:
Comparable uncontrolled price (CUP) method;
Resale price (RP) method;
Cost price (CP) method; and
Other (Other) internationally accepted method.

The CUP, RP and CP methods are favoured. The use of another method is acceptable when a company can demonstrate that the first three methods cannot be applied, when the other method is internationally  accepted, and when it can be appropriately applied in the circumstances.

The guidelines also set out a ‘list of 10 documents’ that the Revenue officers will require when examining a company’s TP practices and transactions. The ‘list of 10 documents’ is as follows:

1. Documentation relating to the structure and nature of the company and the international group to
which it belongs;
2. Budgets, business plans and financial projections;
3. Documentation setting out the company’s business strategies and the reasons for their adoption;
4. Documentation setting out the company’s sales and operating results and the nature of its dealings  with related parties;
5. Documentation setting out the reasons for entering into significant international dealings with related  parties;
6. Pricing policies and documents relating to product profitability, relevant market information, profit  contributions, functions performed, assets used and risks assumed;
7. Documents setting out the reasons for the company’s selection of a particular pricing methodology or methodologies;
8. Where other methods have been considered and rejected, details of those other methods, including the reasons for their rejection;
9. Documents evidencing the negotiation process taken by the company in relation to its international  dealings with related parties and the basis of the negotiations;
10. Other documentation determining the market price.

The guidelines also allow companies to enter into an Advance Pricing Arrangement (APA) with the  Revenue Department. Companies wanting to make an APA can do so by submitting an application to the  Revenue officers and attaching all the relevant documents pertaining to the pricing issues.
