This spreadsheet of budget options reflects CBO's estimates, assumptions, and projections at the time the Options for Reducing the Deficit: 2014 to 2023 was released; that is, the spreadsheet is not continually updated. Nearly all the estimates for the revenue options were prepared by the staff of the Joint Committee on Taxation (JCT).
On December 5, 2013, CBO revised the Collected Tables to correct display formats.
On June 12, 2014, CBO corrected a column heading in the table for Revenues, Option 35.
