Thailand is considering forcing online giants such as Amazon.com Inc. and Facebook Inc. to collect value-added tax on e-commerce sales, echoing an Indonesian clampdown on transactions that skirt the levy.
Cross-border purchases by Thais routed through global online marketplaces, as well as booming domestic sales in the so-called social-commerce sector, should incur the tax. But overseas vendors aren’t always aware of such obligations, and many Thais selling informally via social media avoid them.
