When conducting tax registration, there is also a very common misunderstanding of tax and business registration.
Tax and business registrations are not necessarily the same, although several items in these registrations are identical.
In practices, when you decide to set up a business, the business registration is the first step to make your business registered at public sector. That is when the Ministry of Economic Affair (in charge of business registration when at Central government) informs tax authority of your business registration for business convenience and for tax purposes . But if any businesses have completed tax registration solely for VAT tax purpose, the tax registration DO NOT serve the business registration purpose. That means, your business is in VAT tax compliance, but not yet in business registration compliance.
