Name reservation

New Hampshire law allows an available LLC name to be reserved for 120 days. The fee is $15, plus the $2 electronic handling charge if filed electronically.

Reservation is optional. If you are ready to form the LLC, filing the Certificate of Formation is usually more direct.

Trade name

New Hampshire does not use the name reservation process to reserve a trade name. A trade name is a separate registration concept and should not be confused with an LLC legal name.
