Value added tax (VAT) is a tax levied on added value acquired in the process of the transaction of goods or the provision of services. VAT is imposed on value generated at each step of a transaction, and applies a VAT rate of 10%. Certain supplies are eligible for VAT zero-rating or VAT exemption. VAT zero-rating is the same as VAT exemption in that no VAT is charged. However, only VAT zero-rating allows input VAT deduction for VAT incurred in relation to the VAT zero-rating supplies. The VAT imposed on businesses is calculated by subtracting the input tax from the output tax.

Value added tax should be reported and paid every 6 months, and the taxable period of 6 months is divided into 3 months for a preliminary report.
