There are similar (or higher) taxes in NH. We camouflage some of them as "fees" that you pay every year instead of the T word. If you work in massachusetts and live in NH, youll still have to pay MA income tax and youll have less opportunities to get it refunded. Vehicle inspections are a little more strict in NH. Nearly everything driving related expires on your birthday/month. They remind you of your birthday by sending you bills. Border towns are still gonna have a 1.5- 2 hour commute to the Lincoln/Loon mt area. Firearms are more common, but it's still pretty rare to actually see someone with one. NH only has medical and decriminalized cannabis. Up to 3/4ths of an ounce will result in a ticket and confiscation, anything more or crossing state lines with it is still arrest if i recall. (Im not saying you or your S.O do any of that but it is a difference from massachusetts)

NH has the better boardwalk at Hampton beach, but MA has the better physical beach location with Salisbury beach . NH doesn't require helmets or seatbelts if over 18.

Thats all i got off the top of my head. Hope it helps your decision-making process.
