Rauner quickly vetoed the tax hike and the underlying budget plan.
The bills then returned to the Senate, where members successfully voted to override the governorís veto of the tax hikes and spending plan.
The override of the tax hike portion of the budget passed on a 36-19 vote, with one Republican voting yes, state Sen. Dale Righter. Righter also voted in favor of the tax hikes in order to send the bill to the governor in the first place.
The package will now head to the House, where it will require a three-fifths majority vote to override the governor.
A supermajority of House members on July 2 passed the budget bills to the Senate with votes to spare, with 15 Republicans signing onto the tax hike portion of the plan.
If the House successfully overrides Raunerís veto, the budget package will become law.
The personal income tax rate would increase to 4.95% from 3.25% and the corporate income tax rate to 7% from 5.25%.
House Speaker Mike Madigan said he will not call an override vote July 4
