Income tax legislation Clears Finance Committee

The Senate Finance Committee has approved two measures reforming Oklahoma’s income tax laws. Legislation approved by the committee on Tuesday includes Senate Bill 1623, by Sen. Mike Mazzei, R-Tulsa, and Senate Bill 1571, by Sen. Clark Jolley, R-Edmond.

SB 1623 lowers the state income tax over a two-year period and eliminates most special interest tax preferences. Mazzei said the bill is the result of the Legislature’s Task Force on Comprehensive Tax Reform.

“As these measures move through the legislative process, lawmakers will have ample opportunity for careful consideration and deliberation,” Mazzei said. “Each bill embodies the belief that lowering taxes and enabling Oklahomans to keep more of their hard-earned money while continuing to fund core state functions will result in job creation and greater economic growth for our state.”

Sen. Clark Jolley, Senate Appropriations Chairman, is author of SB 1571, also known as the OCPA/Laffer Plan, to phase out the state income tax.

“The committee vote was a crucial step for all of us who believe eliminating the income tax is the right thing to do for Oklahoma,” Jolley said. “Tuesday’s committee action means meaningful dialogue and debate can continue as we work to create greater prosperity for our citizens.”
