Fiscal subject related
Also, to register for VAT in Portugal, companies need to submit the necessary documentation to the Portuguese tax authorities and obtain a VAT identification number, specifically for VAT purposes but also for other activities. The deadline for VAT registration is 15 days after the company is established with a business registry. From a fiscalization perspective, this regulation and the special number that companies will receive are important because they allow access to the portal of the tax administration. The flow for registration is: completing the registration form; submitting the application electronically through the portal; waiting for confirmation from the tax administration; and receiving a VAT number upon approval.
It is important to mention that non-EU-based companies are required to appoint a fiscal representative. A fiscal representative acts as an intermediary between non-EU businesses and the Portuguese tax authority.
