One complication for the FY 2018 budget process is that discretionary spending is scheduled to decrease by billions from FY 2017 levels. The reason for this decrease is Congress’ solution to previous spending impasses: the Budget Control Act of 2011 (BCA). This act set limits on how much can be spent on defense and non-defense discretionary spending for future years. While Congress frequently authorizes additional spending beyond the caps the act sets, if they fail to alter the FY 2018 spending level, it would reduce the discretionary budget by $110 billion.
