Not really. I left Germany last year. As I wasn't a citizen and I'm not now a resident, I'm not a tax resident of Germany. Edit: clarification: I specifically de-registered with the German tax system, as required by German law. And to establish a new residency, I would have to live more than 180 days in that country, which I haven't yet.

I have multiple citizenships, so I'm not automatically a tax resident of a country I'm a citizen of.

I'm an edge case for tax laws.

Unless the us is one of those citizenships which mandates filing. And I suspect that if you dodge tax residency by avoiding 180 days anywhere I figure you’re at risk to any border agent with a sore ass having a bad day.

I'm not "dodging tax residency" - I'm legitimately travelling.

There's a lot of discussion on this in the digital nomad community. You literally can't register as a tax resident without spending at least 180 days in a country, for most countries. And yes, some tax authorities get a bit strange about people not having a tax residency for an extended period, but we're just following the rules.

The US is different because of the Federal/State tax split, and Federal taxes don't depend on residency. Not many other countries have this split.

Australia (one of my citizenships) is moving towards having to file tax returns even if not resident, but afaik it's not there yet.
