More than half of all Americans – 58% – feel like they are not on track for retirement, according to a study from Ameriprise Financial. And a recent survey from Bankrate.com shows that 26% of Americans between the age of 50 and 64 have saved nothing at all for retirement. These and a host of studies and surveys support what many Americans already know: The majority of us are financially unprepared for retirement.

Many people who don’t have the money to retire in place – that is, at home – may look for alternatives: either abroad, where it’s possible to settle down with a lower cost of living and access to affordable healthcare in some exotic corner of the world (see What Does Retirement Abroad Cost?), or a different, more reasonable corner in the U.S. (see Finding a Retirement-Friendly State).

But where to go? We looked at data from Bankrate.com’s “Best and Worst States to Retire” list  to determine which states are the most expensive, taking into consideration each state’s cost-of-living rank as well as its tax-rate rank. We looked at the 10 worst (i.e., most expensive) states in each category, and found six that made top 10 appearances in both categories – making them the priciest places to retire in, overall. Here's the roster, starting with the most expensive state.

New York

Tax Rate Rank: 50 (highest)

Taxpayers pay $6,993 per capita in state and local taxes each year, and the top rate for capital gains is 31.5%, the second-highest rate in the U.S. (after California).

Its 2012 tax burden of 11% ranks 6th highest in the nation, and taxpayers pay $5,237 per capita in state and local taxes. State and local governments collect about $1,365 per person for property taxes. The state sales tax is 7.25% (the highest among the states mentioned here), and the combined rate in special city/county taxing districts can be as high as 9.75%.Although Social Security and Railroad Retirement benefits are exempt from taxes in California, all other sources of retirement income are fully taxed. Topping out at 33%, the state has the highest capital gains tax rate in the country. 

New Jersey

Cost-of-Living Rank: 43 (8th highest)
Tax Rate Rank: 48 (3rd highest)

Property tax collections are about $2,989 per person, which ranks 1st nationally. New Jersey is one of only two states that levy both an inheritance tax and an estate tax. While close relatives are generally excluded from the inheritance tax, other beneficiaries face tax rates ranging from 11% to 16% on inheritances over $500.The The estate tax is set to disappear in 2018.

Tax Rate Rank: 43 (8th highest)
State Income Tax: 3.75% to 5.99%
State Sales Tax: 7.0%

The state had a 2012 tax burden of 10.8%, and taxpayers pay $4,998 per capita in state and local taxes. Property taxes are about $2,282 per capita, which ranks 6th nationally. Railroad Retirement benefits are exempt from taxes, and so are Social Security benefits if they fall below the applicable threshold ($80,000 for single filers and up to $100,000 for joint filers). Other retirement income is taxable at ordinary income tax rates.

Property tax collections amount to about $2,331 per capita, which ranks 5th nationally. Vermont taxes most retirement income at ordinary income tax rates, including Social Security benefits, which are taxed up to 85% (in sync with the federal rate) of benefits. Railroad Retirement benefits are exempt.

The Bottom Line

Several states have tried to make their tax systems more appealing to retirees. Maine, for example, boosted the amount of pension income that can be excluded from state taxes, and Nebraska increased its exemption for Social Security income. The federal exclusion for estate tax is currently $5.45 million, and both New York and Maryland are incrementally increasing their exemptions to match the federal amount.

Whether you are concerned with making your money last longer during retirement or leaving more assets to your children, the local cost of living and tax rate may be an important consideration during retirement. Not that non-financial factors – your interests, hobbies, comfort, health and proximity to friends and family – aren't important when choosing a retirement destination. Just bear in mind that wherever you retire (be it in place, in another state, or abroad) can have a considerable impact on your finances, as well.
