BTW if you are a Portuguese citizen you can register your company in a easier way, from this page: https://e-estonia.com/component/e-business-register/
Finally if you want to open a company in estonia you will need a physical address, fortunately the government is aware of this hurdle, and in it's website suggest an handful of providers: https://e-residency.zendesk.com/hc/en-us/articles/205207022-...
The one with the nicer website is LeapIN, that has very affordable prices...
I am sure is not something that they would put on the first page, however I am a little surprise.
Do you care to elaborate ?
Almost every country in the world taxes their residents' income, even if it arrives from a company abroad. And US (in)famously taxes their citizens' income, even if they do not live in US.
So if you run a company remotely, you still have to check with your local tax rules to see how much tax you may need to pay if this company pays you salary or dividend.
Those are not "extra" taxes, those are regular taxes on your income...
edit: Here is article about it in finnish http://www.yrittajat.fi/fi-FI/uutisarkisto/a/uutisarkisto/vi...
Translation of key point (by me)
– Jos liiketoiminta tapahtuu Suomessa ja omistajat ja päätöksentekijät asuvat Suomessa, myös verotus tapahtuu Suomessa, vaikka yritys olisi perustettu Viroon. Jos yritys harkitsee toimivansa Virossa, pitää aidosti mennä lahden taakse, asua siellä, pitää kiinteää toimipaikkaa ja harjoittaa liiketoimintaa, Akselin sanoo.
"If business operations are conducted in Finland and decision makers live in Finland the taxation also happens in finland even if the company has been founded in Estonia. If company thinks of operating in Estonia, you have to actually go over the sea and live there, have actual business location and operate your business there Akselin states. (this is a guy from finnish Accounting firm)"
(my note: it doesn't have to have all of the above meaning operations and management, it could be one of the above for example just management living in Finland)
