We relieve entrepreneurs of administrative burdens, allowing them to focus on developing their business.

Control of Income, Expenses, and Reporting

Portuguese legislation includes many nuances: tax regimes, VAT rules, reporting deadlines, employer obligations, and specifics for residents and non-residents.

We provide consultations on:

  • which type of activity to choose when starting a business
  • which taxes and reports are mandatory
  • how to legally reduce your tax burden
  • which benefits are available for new residents
  • which documents must be kept and submitted

Our consultations help you avoid mistakes and penalties, while building your business in full compliance with the law.

No. Many steps can be completed remotely. However, some stages may require personal presence or a power of attorney. We will help you choose the best option.

How to choose between a sole proprietor and a company?

It depends on your activity volume, expected income and service type. We will analyze your situation and recommend the most suitable structure.
