Do I need to register my Vietnam company for tax separately?

No separate application is needed for the tax code: the enterprise code on your registration certificate is also the company's tax code. You still set up a digital signature for online filing, register e-invoices and file the first tax returns on time. We set these up with your accountant after registration.
