Biennial Budget Act

Biennial Budget Act - Amends the Congressional Budget Act of 1974 to revise the Federal and congressional budget processes by establishing a two-year budgeting and appropriations cycle and timetable, beginning in the 103d Congress. Defines the budget biennium as the two consecutive fiscal years beginning on October 1 of any odd-numbered year.

Devotes the first session of any Congress to the budget resolution and to appropriations decisions, retaining current deadlines in most cases. Changes relevant deadlines as follows to conform to the biennial scheme: (1) from April 1 to March 31 for the Senate Budget Committee's report on the concurrent resolution on the budget; (2) from June 15 to September 30 for completion of congressional action on reconciliation legislation; and (3) from June 30 to September 30 for completion of congressional action on appropriations bills. Devotes each second session to authorization activity, subject to deadlines of: (1) May 15 for the submission of the Congressional Budget Office (CBO) report to the Budget Committees; and (2) the last day of the session for completion of congressional action on bills and resolutions authorizing new budget authority for the next biennium.

Changes from January 15 to February 15 of each year the date by which the CBO Director must submit to the Congress a report on authorizations. Requires the Director of the CBO to issue four-year projections of congressional budget action. (Current projections are on a five-year basis.)

Amends provisions relating to the reconciliation process to: (1) increase from 20 to 100 hours the time of debate permitted in the Senate with respect to reconciliation measures; and (2) make it out of order in both the House and the Senate to consider any reconciliation legislation changing any provision of law other than one relating to new budget or spending authority, revenues, or the public debt limit.

Revises the extent of projections to be included in CBO analyses of reported bills.

Conforms provisions governing the President's budget to the biennial framework.

Changes the due date for the President's report on estimated budget outlays and proposed budget authority, making the report due at the same time as the President's budget. Requires the Joint Economic Committee to submit its evaluation of these estimates by February 25 of each odd-numbered year. (The current annual deadline is March 1.)

Directs the heads of Federal executive agencies, the Comptroller General, and the Directors of the Congressional Budget Office, the Office of Technology Assessment, and the Congressional Research Service to provide studies, analyses, reports, and other documentation concerning program administration to assist the standing committees of the House and the Senate having jurisdiction over the programs in question.

Amends the Rules of the House of Representatives to conform to the biennial framework.
