The so-called standings bill passed the Republican-controlled House last week.
Sen. Robert Dvorsky of Coralville, who sponsored the bill, says Senate Democrats will likely reject the House version Tuesday.
Last week, Republicans added policy items to the bill, including one that would change collective bargaining rules. Republicans also added their version of a plan to regionalize Iowa's mental health care system.
The standings legislation includes a series of budget items, such as basic school funding, as well as some new fiscal and policy items. It's traditionally viewed as the last opportunity to move legislation before the session ends.
