Freelancing in Germany for clients only in U.S.

I've read through numerous posts but all the freelance scenarios seem to be about freelancing in Germany.

I moved here in Nov. with my husband who works for a Germany company. We're residents. I've been a freelance journalist in the U.S. for two years and just moved my office here and do the same work. I have no Germany clients and don't plan on having any. I'll be paying U.S. taxes -- I assume -- but filing in Germany, too, which I understand is the law here. I never thought to register my "freelance" business here until I started reading posts. Do I need to register it if I have no Germany clients.

Thanks.

I really hope what you write is in Spanish.

Yes you have to register as a freelancer here. Good luck with that.

Could you do it for years and not get caught? probably.

Thanks. No we plan -- for now -- to be here for good so no skirting the law, besides, I understand I have better luck getting my kids into a kindergarten if I'm an officially "working" mom.

As far as I know, if your business, freelance or professional is centered in that place (here being Germany) it needs to be registered with the area you live in. When I was in Hamburg for the first time trying to get my visa, I had to register myself as a freelancer. So I can only assume so? But if you've gone so far as to not need registering yet or have someone down your throat to get you to do so, then I guess not then hehe.
