Not to be too grim, but as you're approaching retirement, you need to think seriously about the only two certainties in this world: death and taxes. On the bright side, you can do a number of things to minimize your tax bill under the new tax law--and one potentially big tax-saving move is to move in retirement. The tax situation in every state varies and can make a big impact on any budget, particularly for people living on a fixed income. To help retirees sort through the differences, Kiplinger has mapped out a state-by-state guide to taxes, classifying each state based on its treatment of retiree finances from least tax-friendly to most tax-friendly.

We also pinpointed 50 great retirement destinations in the U.S.--one in each state--that all offer other attractive advantages for retirees, such as living costs, safety, median incomes and poverty rates for retirement-age residents, as well as residents' sense of well-being and the availability of recreational and health care facilities. These are the places to retire we picked in each of the 20 states that we've deemed either tax-friendly or most tax-friendly for retirees. They're literally all over the map, so you're bound to find at least one spot to suit your retirement lifestyle.
