# Tax Info ### Overview Depending on the country of sale, Developers must register their tax information (TAX ID) after completing membership registration. Since the requirement to enter a TAX ID may affect the Settlement amount according to country-specific tax regulations, please ensure that accurate information is provided. Tax information can be registered directly through \[Account Settings] > \[Membership Information] > \[Tax Information]. ### TAX ID Collection Guide TAX ID is a crucial factor in determining a Developer’s residency status. ONE store provides services in South Korea, Singapore, Taiwan, and the United States. Among these, Singapore determines residency status based on whether a TAX ID is provided, which directly impacts the Settlement amount. To manage country-specific policies consistently, ONE store collects TAX IDs for all countries. This is an essential step for smooth Settlements, and all Developers are required to register their TAX ID accordingly. However, for services provided in the United States, a separate Settlement process managed by DT applies instead of ONE store. As a result, Developers do not need to enter a TAX ID directly but must proceed with Tipalti registration via the \[Account Linking] button. \ [\[Go to related information\]](https://onestore-dev.gitbook.io/dev/chi/help/faq/global#is-it-mandatory-to-sign-up-for-tipalti-to-sell-paid-apps-in-the-united-states) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
