1. Consumption Tax Treatment of Claude Subscription Fees

(1) Requirements for Japanese Consumption Tax
Under the Japanese Consumption Tax Act, consumption tax is imposed on:

the transfer or lease of assets, or the provision of services for consideration in the course of business within Japan; and
the importation of foreign goods.
The key requirement in this case is that the transaction is conducted "within Japan."

Services such as Claude, which are provided over the Internet, are classified as electronic services (telecommunication services) under the Consumption Tax Act. These include services such as the online distribution of digital books, advertisements, and other digital content to customers in Japan.

Accordingly, payments made for Claude subscriptions are treated as taxable transactions for Japanese Consumption Tax purposes.

 
(2) Business-to-Business or Business-to-Consumer Electronic Services?
Electronic services supplied from overseas are classified as either:

Business-to-Business (B2B) electronic services, or
Business-to-Consumer (B2C) electronic services.
If the service is classified as a B2B electronic service, the reverse charge mechanism applies. In that case, the Japanese business receiving the service is required to report and pay Japanese Consumption Tax as a "specified taxable purchase."

On the other hand, if the service is classified as a B2C electronic service, the overseas service provider is responsible for reporting and paying Japanese Consumption Tax.

Claude subscriptions are not contractually restricted to business users and are equally available to individual consumers. Therefore, Claude is generally regarded as a Business-to-Consumer (B2C) electronic service for Japanese Consumption Tax purposes.

"Effective April 1, 2026, Anthropic will collect 10% Japanese Consumption Tax on services provided to customers in Japan in accordance with Japanese tax law. Anthropic has completed its registration as a Qualified Invoice Issuer."
