Although retirement is a time to relax,  planning for your retirement can be stressful and difficult. However,  by doing a little research you can make the most out of your retirement. Market Watch has put together a helpful article explaining  tax issues related to retirement, and what states are better to retire  in. You can find a snippet of their article below.
 
As you enter retirement, probably the  largest and most daunting expense you encounter will be taxes. And we're  talking not just of a benign single item of expense, but quite possibly  many different kinds of levies. Each one of our 50 states can enact  and enforce state and local taxes by the dozen, as well as property  taxes by the hundreds, and countless more.
These taxes can vary so much in size  and scope from place to place that they sometimes become key factors  in your decision of where to retire -- indeed, whether you choose to  retire at all.
People who retire to low-tax or no-tax  states have an economic advantage over those who do not. But only nine  states have no broad-based state income tax. Those states are: Alaska,  Texas, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Washington  and Wyoming. (In New Hampshire and Tennessee, income tax is limited  to dividends and interest income.) See this Federation of Tax Administrators  page for more details on state tax rates.
One means to determine which state is  the least costly in terms of total taxes is to check a study called  "Tax Freedom Day." That's the day on which the ordinary American's  total federal, state and local tax bill is fully paid from his or her  earnings for the year to date. Ostensibly, this is the day you stopped  working for the government and started working for yourself; that is,  the day you earned enough to pay your federal, state and local taxes  and are now starting to make money you'll be able to spend on things  for yourself.
