Yes, corporate tax registration is mandatory for businesses operating in the UAE under the new tax regime introduced in 2023. Any business, whether based on the mainland or in a free zone, generating taxable income above a specific threshold must register for corporate tax with the Federal Tax Authority (FTA). This applies to both local and foreign entities conducting business within the UAE. Failure to register can result in penalties, making it crucial for businesses to comply with the registration requirements to avoid legal issues and ensure proper tax filing.
