Outgoing Gov. Olene Walker proposed a sweeping series of changes to Utah's tax structure Monday, including a flat-rate income tax and charging sales taxes on consumer services such as health care.

"The bottom line is to broaden the base and lower the rate," Walker said, calling her proposal friendly to both families and businesses in the state even though property taxes would have to go up by some $300 million to offset rate cuts in income and sales taxes.

Overall, the state's tax take would stay the same, says Walker, but the tax system would be fairer and more stable. She stressed that if something isn't done about the state's dwindling tax base, Utah will face a $200 million revenue shortfall within a decade.

"The critical, critical question is, can we afford to do nothing," the governor said.

Under her plan, the state income tax rate would drop from a high of 7 percent to a flat 4.9 percent for everyone under the most likely alternative.

The state sales tax rate would be rolled back 1 percentage point, to 3.75 percent, but eliminated from many business purchases and charged for many consumer services.

Other changes sought by the governor include eventually eliminating the corporate income tax, allowing school and other special districts to adjust property taxes for inflation without holding truth-in-taxation hearings and equalizing the sales-tax rate throughout the state.

Details of the proposal are contained in an inch-thick volume titled "Governor Olene Walker's Recommendations on a Tax Structure for Utah's Future," available online at www.utah.gov/governor.
