You no longer need physical presence to register your company and do business through the programme but you should still be very careful about taxation, tax residency whether personal or corporate gets very complex very fast and I highly recommend talking to a tax expert

Yes, the country/countries where your physical office(s) is/are located (or rather, where people - founders or employees - are doing the work that is the basis of the revenue on which you're generating a profit) will likely want a piece of the pie.

Certainly, a decade or so ago, it was popular to register a limited company in the UK whose physical presence was on the continent. Invariably, this meant dealing with both tax authorities.

It seems to have lost its attractiveness after laws for GmbH and similar were relaxed in various countries. Brexit has pretty much killed any remaining demand, at least for real companies. (As opposed to shell companies for tax evasion or money laundering purposes, for which the UK remains as popular as ever - and which are a major reason for big money backing Brexit, as the EU has been looking to crack down on the practice.)
