We currently owned a small HVAC company in Austin, TX but is thinking of relocating our family to CA to be closer to family. Our kids will be going to school in California. We will be coming back and forth from California to Texas to manage the business. Will we be subject to California state income tax since Texas has no state income tax even if the business is 100% conducted in Texas? We are LLC filing S Corp.
I would suggest you contact a CPA or Enrolled Agent in California to help you. The answer is probably yes but you should get some good advice. That is not the sort of question that can be answered easily in this forum.
