BANGKOK, Sep 1 (Reuters) - Thailand on Wednesday will start collecting value added tax (VAT) from foreign technology companies and expects to raise at least 5 billion baht (US$154.70 million) in additional revenue each year, a senior official said.

Foreign platforms providing electronic services in Thailand will have to register for VAT payments, senior finance ministry official, Ekniti Nitithanpraphas, told reporters.

So far 69 companies have registered from a target 100, according to Ekniti.

The companies are divided into five categories including platforms getting income from e-commerce and advertising like Facebook and Google, intermediaries such as ride-hailing app Grab have and streaming services such as Netflix, he added.

Companies with revenue of over 1.8 million baht will have pay VAT of 7per cent, which has to be paid every month, he said.

The ministry's target of 5 billion baht of additional revenue is a minimum because that goal was derived before the pandemic.

Thailand collects about 800 billion baht annually from VAT.

Last week, the government approved an extension of the current 7per cent VAT rate until September 2023. The VAT rate has been at 7per cent since the 1997-98 Asian financial crisis.
