Idaho made about 25 percent more in corporate income tax revenues between July and September than it made during the same time in 2012, lifting Idaho's total tax revenues above other Rocky Mountain states.
A report Thursday from the Rockefeller Institute of Government said Idaho fell one point below the national average for revenue growth between July and September. Idaho had a 5.1 percent increase; the national average was 6.1 percent.
But the Gem State's 24.8 percent growth in corporate income tax revenues ranked sixth in the U.S., far outpacing the national average of +1.9 percent and the Rocky Mountain region's average of -7.2 percent.
"The large variation among states' corporate income tax revenues is due to volatility in corporate profits and in the timing of tax payments," the report said.
The report did not include all states. Wyoming was the only Rocky Mountain state excluded from the report. Montana's personal-income and sales-tax revenues were not included.
