Last month it said general revenue would fall short even of that mark, and that another $900.1 million less is expected for FY 2017, which begins on July 1.

Monday, Mazzei said the drop is likely to be closer to $1 billion.

“There are going to be a great number of financial management changes discussed,” Mazzei said of the upcoming legislative session. “All involve difficult decisions. I’m trying to provide as many options as possible.”

The 0.25 percent reduction works out to about $150 million a year less to the state treasury when fully implemented, and comes on top of more than a decade of income tax cuts that the Oklahoma Policy Institute, a liberal-leaning advocacy organization, says total more than $1 billion a year.

Conservatives contend the reductions have made the state more attractive to business and forced state government to operate more efficiently.

Mazzei said the problem with existing financial tax-cut triggers is that they allow no margin of error. His bill proposes requiring general revenue estimates equal the cost of the reduction plus 3 percent of the previous year’s general revenue.

Mazzei would not speculate on the chances of the Republican-controlled state government backing off the tax cuts.
