Seniors in Arkansas, the second on our list of cheapest states to live in the US for seniors do not have to pay taxes on social security while other forms of pensions are partly taxable (retirees are provided with a deduction of $6,000). Besides affordability, the state boasts mild climate and great natural diversity with mountains on the north and Mississippi River on the east. On the negative side, Arkansas is named as the state with the worst quality of healthcare in the US, so it is not the best choice for people with chronic conditions who need frequent medical care.
