With the signature deadline less than a month away, Oregon business groups say they are confident of forcing a statewide vote on the Oregon Legislature's $733 million income tax increase on corporations and high-income people.

With the signature deadline less than a month away, Oregon business groups say they are confident of forcing a statewide vote on the Oregon Legislature's $733 million income tax increase on corporations and high-income people.

It would take more than 55,000 signatures. Pat McCormick, a spokesman for the Oregonians Against Job-Killing Taxes, says opponents are well on their way toward gathering that number. He wouldn't provide an estimate of signatures gathered so far.

An election would be held in January.

Public-employee unions, education and human-services advocates already are preparing a campaign to support the increases as a matter of tax fairness and protecting schools and vital services from cuts.
