The Thai Revenue Department issued guidance to revise the input tax allocation basis for registered operators selling goods outside Thailand.
- Registered operators engaged in both businesses subject to value added tax (VAT) and businesses not liable to VAT under Section 77/2 of the Revenue Code must first apportion the common input tax on goods/services used for both types of businesses based on the revenue proportion of the business which is not liable to VAT. The remaining input tax can then be deducted from the output tax in the VAT calculation. For example:
- In May, Company A, a registered operator, has THB16 million in revenue from domestic sales and THB4 million from sales with contracts and deliveries made abroad (20% of total revenue).
- Company A has THB1 million in common input tax. Thus, it must first apportion 20% of the input tax (THB200,000) to the business which is not liable to VAT, and the remaining THB800,000 can be deducted from the output tax.
- Registered operators engaged in (1) businesses subject to VAT, (2) businesses not subject to VAT, or (3) businesses not liable to VAT under Section 77/2 of the Revenue Code must first apportion common input tax on goods/services used for all three activities based on the revenue proportion of business not liable to VAT. The remaining input tax can then be allocated in accordance with Section 82/6 of the Revenue Code. For example:
- Company B, a registered operator, exports and sells fresh chicken both domestically and internationally. In 2023, its revenue from VAT-liable exports and VAT-exempt domestic sales is split equally.
- In May 2024, Company B has THB6 million in export revenue, THB10 million in domestic sales, and THB4 million in foreign sales contracts (20% of total revenue).
- Company B has THB1 million in common input tax. Thus, it must apportion 20% (THB200,000) to business not liable to VAT first. The remaining THB800,000 is then allocated equally per the previous year's revenue ratio (50:50), allowing a deduction of THB400,000 from the output tax.
KPMG observation
According to this guidance, a VAT-registered operator is required to complete two steps of common input tax allocation. Initially, a VAT registered operator needs to conduct the apportionment of input tax to the business not liable to VAT. Subsequently, the remaining input tax can be allocated among businesses subject to VAT and business not subject to VAT. In addition, these two steps must be done every month in which a registered operator has income from the business not liable to VAT.
