Hi Hiorki!
First of all, apologies for the late reply!
Estonian e-residency company makes the most sense for truly nomadic digital nomads who spend less time in each country (generally not more than a few months) than the minimum time required to become a tax resident there.
Still, the specifics depend on the country where you are indeed registered as resident or spend the majority of your time. A good place to start would be the tax treaty between that country and Estonia, as well as the domestic laws of that country. In most cases, it would rarely be an issue until you regularly spend the majority of your time in any given country while working on your business. And the first issue that may crop up isn’t that of corporate residency but of a permanent establishment (i.e. having to pay tax locally on the profits generated there).
Keeping this in mind, especially where the business is service-based and the entire company is essentially the services you personally provide, then you may want to incorporate that business locally to avoid dealing with questions about corporate residence, permanent establishment, etc.
If there’s no natural country where you spend most of your time, then in most cases you’d be fine with a company registered abroad without any additional hassle.
The same goes for a non-personal service-based business (e.g. if it’s a digital product or service) and the company has strong ties to Estonia or wherever it’s registered (e.g. employees there, ideally in higher positions). In that case, as an owner, as long as you’re mostly working in the business as opposed to on the business, you’d usually be fine if you register a business or as a freelancer where you live and invoice the company according to market rates for your services and pay tax on those locally. Or register a permanent establishment locally. But this only makes sense if it’s no longer a one-person business.
I hope it helps! And I’d always recommend consulting a local tax advisor of the country where you spend the majority of your time as well.
