When you incorporate in Delaware but have your primary operations or HQ in another state you will likely have to file as a foreign entity in that state and pay a fee. That is just the cost of doing VC business. Each state is a bit different, even with regard to C-corps and LLCs. So you’ll have to talk to a lawyer or do some Google searching to find out about your State.
