Business and moving alot? Any military deal with this?

Has anyone had to move alot while having their photography business? I know this isn't ideal. But is it possible? Being that I'm military and moving alot and then deploying for months at a time doesn't help either. I know all the paper work/legal stuff would have to be re-accomplished if moving into a new state. But has anyone had to do this at least once or more than once? Any military members do this when they can, and if so do you register or keep it under the table so to speak? If you don't want to publicly say that is fine, you can pm if you like.

As a side note, I am not trying to promote or support under the table work, but if we are being honest here, I think we all have done it at least once in our lives.

I retired from the Army in 2008. For about twelve of my twenty years of service, I ran a custom fabrication shop on the side. I built custom cars, trucks and bikes. Of course it started out as a cash only, under the table deal but when things started getting more serious, I had to get legit. I operated in Tennessee and Georgia and made sure I met all the legal requirements in both states. When I deployed or was too busy as a drill instructor to run the shop, I still kept everything current and reported zero income.
