2 U.S.C. § 639 — Reports, summaries, and projections of Congressional budget actions

(a) Measures affecting budget authority, revenues, or tax expenditures. (1) When a House committee reports a bill, joint resolution, or committee amendment that provides new budget authority other than continuing appropriations, or changes revenues or tax expenditures for one or more fiscal years, the accompanying report—or a statement made available for an approved amendment not reported to the House—must be prepared after consulting the CBO Director and must: (A) compare the measure with the applicable allocations in the reports under section 633(b) for the latest agreed concurrent budget resolution; (B) include a CBO projection of how the measure would change budget authority, outlays, revenues, or tax expenditures under current law for those fiscal years and each of the next four fiscal years, if the projection is timely submitted; and (C) include a CBO estimate of new budget authority for aid to State and local governments, if timely submitted. (2) When a conference report or specified related amendment provides new budget authority other than continuing appropriations or changes revenues, the managers’ statement must contain the paragraph (1) information if timely available. If not available when filed, the committee must make it available to Members as soon as practicable before consideration. (3) PAYGO estimates. (A) The House and Senate Budget Committee Chairs must request from the CBO Director an estimate of the budget effects of PAYGO legislation. (B) Estimates must use CBO baseline estimates consistent with section 907. (C) The Director may not count timing shifts, as defined in section 932(8), in those estimates.

(b) Current budget-action tables. (1) At least monthly, the CBO Director must give House and Senate committees reports tabulating congressional action on bills and joint resolutions that change budget authority, revenues, or tax expenditures for fiscal years covered by a budget resolution. Reports must include current comparisons of aggregate and functional levels, including outlays, in the latest resolution; levels in measures reported or adopted by committees, either House, or Congress; and levels provided by law for the fiscal year before the resolution’s first fiscal year. (2) Each Budget Committee must make summary scorekeeping reports available to its Members: (A) at least monthly and often enough to accurately show the budget’s current status; (B) including summaries of the tables under paragraph (1); and (C) based on paragraph (1) information without substantive changes. The House Budget Committee chair must submit these reports to the Speaker.

(c) Five-year projection. As soon as practicable after each fiscal year begins, the CBO Director must issue a report for that fiscal year and the next four fiscal years showing: (1) total new budget authority and outlays for each year; (2) revenues and their major sources, and any surplus or deficit, for each year; (3) tax expenditures for each year; and (4) entitlement authority for each year.

(d) Scoring rules. Estimates under this section must follow the scorekeeping guidelines set under section 902(d)(5).
