That usually depends on which country you are from. Germany, for instance, follows a residence based taxation. So if you spend a substantial amount of time outside Germany, cut all ties (no spouse, apartments, cars in Germany) and don’t have German income (e.g. from rent) you’ll cease to be considered a tax resident of Germany.

In that case you won’t have to pay income tax anymore. However, where it gets complicated is that usually under these digital nomad visas you don’t get a new tax residence nor a tax file number from your new residence country. So you are kind of falling between the cracks and have a hard time opening bank accounts etc.

I’ve been through this whole ordeal and it certainly is an interesting experience with pros and cons.
