I keep getting contradictory information here, so hoping someone can help.
I'm a German and UK citizen and have an apartment in Berlin that I use when visiting. I was told by a border agent a few years ago that, as a German citizen that owns an apartment in Berlin, I need to be registered at that apartment, which I dutifully did. I live and work in London and visit Berlin for less than 90 days a year.
I recently bought another apartment in Berlin which I have just started renting out, generating rental income. This is my first income in Germany.
Having never had income in Germany before, I phoned a tax advisor who was shocked that I was registered in Germany and said that that would generate all sorts of negative tax consequences and complications regarding my UK income and she advised me to re-register. She said she has many clients who own property in Germany which they use for themselves, but live abroad and aren't registered. She's now unreachable by phone or email.
So a few questions:
1. Can (or should) I de-register?
2. Does not de-registering make my tax situation any more complicated in terms of my UK income?
3. Could someone recommend an English-speaking tax advisor that actually knows what they're talking about, is contactable, and could help with my taxes?
Thank you for your help!
