Such businesses, both in and outside of Thailand, will need to notify the government before operating, spokesman Thanakorn Wangboonkongchana said in a statement.
The law will apply to various digital platform services including online marketplaces, social commerce, food delivery, space sharing, ride/car sharing and online search engines, he said.
"They are all increasingly important to the economy and society, so there is a need to oversee them," Thanakorn said.
Last month, the government said it would start collecting value-added tax (VAT) from foreign technology companies including Facebook and Google, intermediaries such as ride-hailing app Grab and streaming services such as Netflix.
