New Hampshire is another popular state situated in New England. That means gorgeous fall foliage, small towns, and plenty of opportunities to enjoy nature. Sales tax is set at 0%, and it has a pretty large population of people 65 or older. In total, 1.4 million people call the state home, with 253,864 of those being seniors. It's also worth noting that New Hampshire has some great healthcare options.
That said, the cost of living is around 18% higher than the national average, but it somewhat offsets this by not having taxes on any retirement income someone might have.
