What if I don't register with New Hampshire?

Does New Hampshire require a registered agent?
Yes: the South Dakota registered agent stays, and ours covers New Hampshire for year one.
Can I form a new New Hampshire LLC instead?
Yes, but South Dakota keeps the original, so you run two companies: the new one files New Hampshire's Annual Report ($102), and the original keeps South Dakota's Annual Report.
How do I withdraw from New Hampshire later?
South Dakota companies leave by filing an Application for Certificate of Cancellation of Registration of Foreign Limited Liability Company; until then, New Hampshire's report stays due alongside South Dakota's filings.
