University officials are considering a plan to raise tuition by 6 percent this fall if the state doesn't increase funding by $125 million for 2012-13.
Administrators say the 10-campus system would need to consider a mid-year tuition increase in the "range of double digits" or make drastic campus cuts if voters don't pass Gov. Jerry Brown's tax plan in November.
The tuition plans were outlined in an agenda for a UC Board of Regents meeting that was posted online Monday.
Board members are scheduled to discuss various tuition scenarios when they meet in Sacramento on May 16. No action is expected until July.
University officials say the amount of the proposed tuition hike could change based on the state's fluid budget situation.
The tuition scenarios are based on the 2012-2013 budget plan the governor released in January. Brown is scheduled to release a revised budget proposal based on new projections that state revenues has fallen about $3 billion below expectations.
UC officials say the tuition increases are being considered because the state cut funding for the UC system by $750 million this fiscal year.
Brown has said that the UC and California State University systems would each lose an additional $200 million if his tax initiative is not approved.
