It‘s complicated for both sides. US citizens have to file their taxes but will be mostly exempt (depending on their income) since they will be already taxed abroad.

Likewise EU citizens may be taxed at home, depending on where the income originates.

So it‘s complicated.

But it‘s true that most countries determine where you are a resident (or have income from there) and then will tax you primarily on that and citizenship has no influence.

It is not true that we are "mostly exempt": only earned income (a narrow definition) is exempt.

And while it is true that many other countries have versions of taxing citizens living abroad for some time or under certain conditions (like having assets at home or conditions that deem the stay abroad "temporary"), there are only two countries in the world that have no mechanisms for stopping this taxation once one has truly and surely severed financial ties: the US, and Eritrea.
