Utah is among nine states that are tax-friendly to wealthy people, a magazine study concluded.

The Beehive State earned an "A-" in wealth-friendliness by Bloomberg Personal magazine.

Other high-ranking states include Wyoming, Alaska, Nevada, Alabama, Colorado, Louisiana and Tennessee.

States most likely to take from the rich were Iowa, Minnesota, New York, Rhode Island, Vermont, District of Columbia, Maine, Montana, Oregon and Wisconsin, according to the study.

The magazine's rankings are based on more than 20 tax-related categories, senior editor Robert Casey said. Income, property and sales taxes, as well as wealth-transfer policies on gift and estate taxes, figured prominently.

Casey said the survey uncovered surprising disparity.

Residents with adjusted gross incomes of $500,000, for example, pay taxes of $49,184 in Idaho and $44,605 in Montana. By relocating to Utah, they could lower that burden to $33,828. If they moved to Nevada, they would pay $7,189 in taxes. By going to Wyoming, they would pay $4,274.

High-income retirees pay $23,270 in taxes to live in Montana and $15,897 to live in Idaho. But they pay only $11,819 to live in Utah and $4,230 in Wyoming.

Casey said there is a correlation between wealth-friendly tax policies and economic growth, he said. The Bloomberg survey found the top wealth-friendly states mostly have healthier economies. Their economic growth was 30 percent over five years, compared with 18 percent for states at the bottom of the ranking.

He added that wealth and capital are more portable than ever. Computer technology makes it possible for wealthy software developers, consultants and others to live and work where they get the best tax deal. As a result, "Many states are actively cutting taxes to make themselves more attractive."

Utah is among states that recognize the correlation between wealth-friendliness and growth, said Mike Christensen, executive director of the Utah Foundation, a nonprofit public-policy research firm. The state designs tax policy hoping to reap economic benefits wealthy residents bring.

While Utah's tax policies help the affluent, they place undue burden on others, said Patrick Poulin, executive director of Utah Issues, a low-income advocacy group. He said lower-wage earners pay a disproportionately large share of their incomes in taxes.

"Wealth is fine, but not when it is buoyed up by the rest of the population," Poulin said. "The working poor in Utah are just getting by."
