Hi Everyone! I am in the process of getting my taxes and legal parts of my business set up and am having an awful time. I currently live in NH and would like to start up my business as a sole proprietorship. However times have gotten tough up here I am considering relocating to Denver, North Carolina to be with family in the upcoming months. I'm nervous as to how this might effect starting a business.
From talking with the local business groups I need to register a trade name in the state of NH. Then comes the business checking account with the company name and my EIN from the IRS (as I have chosed not to use my SSN for security purposes). I know I am required to pay Federal taxes, self-employment tax, and possibly a NH business tax. The problem is I have no idea how much, when, and who I am suppose to pay these to and state offices were not much help in telling me.
If I get everything set up in NH and then have to relocate in a few months, how can I plan a smooth transition? Would I have to stop working until I can get the taxes in NC sorted out? Any help on this or resources would be greatly appreciated! Thank you!
