Get in touchClose to you, wherever you are
An office in Lisbon (visits by appointment only), digital support across Portugal and help for international companies.
Should I stay self-employed or set up a company?
It depends on your turnover, your expenses and your goals. Beyond a certain point, a company can be more tax-efficient, but it also brings more obligations. We run the numbers for your specific case and help you decide on facts, not guesswork.
How much tax will I pay?
There is no single answer: it depends on your tax regime, income, expenses and the benefits that apply. What we do is estimate that figure with simulations throughout the year, so there are no surprises and you can plan your cash flow with peace of mind.
Do you work with clients across Portugal and abroad?
Yes. We work digitally with clients all over Portugal, and with foreign and non-resident companies too. Being close to our clients is not about distance, it is about the support we give.
Will I have access to my tax documents?
Always. Every document we produce for you (returns, reports and correspondence with the Tax Authority) is kept in your personal archive. Your financial information is yours and should always be within reach.
Shall we take care of your company’s accounts?
