Features
Read full description

The NIF is the first step for anyone planning to live, invest or open a business in Portugal. NIF Express handles the application for you — fiscal representation included — and this app puts the whole process in your pocket: • Apply for your NIF without leaving the app — adult or minor, with a guided form and secure in-app card payment (Stripe). • Upload documents from your camera or photo library and see exactly what is missing, with the checklist updating as you send. • Certified electronic signature by email — we tell you when the power of attorney is sent, and your application moves on as soon as you sign. • Track every stage — from submission to the tax authority to your NIF being issued, with a notification at every status change. • Fiscal representation with no surprises — see when it renews, what it costs, and cancel the renewal in the app; you always keep the period you already paid for. The app is available in English, Portuguese, Spanish, French, Brazilian Portuguese, Russian, Ukrainian and Chinese. In-app prices: €49.99 (adult) and €74.99 (minor), VAT included, with one year of fiscal representation. Renews yearly at €49.99; cancel anytime. NIF Express is a service by BOCEAN IMMIGRATION PORTUGAL, LDA — the paperwork is handled by our legal team with the Portuguese tax authority.
