CPA- Where Do I Need One??

[Jorge Ruiz]

Hello BP! 

Got another question that I am sure has been asked 1000's of times and I hope this is the right forum-

I live in Los Angeles, California and am planning to do some out of state investing in Milwaukee, Wisconsin- mostly looking for 2-4 unit properties. 

Anywho I am wondering where I need to file state taxes for my rental income- Wisconsin or California? I would dare say I need that CPA to be in that state? 

Any and all help is greatly appreciated BP!
