Summary: Truth in Budgeting Act - Prohibits the receipts and disbursements of the Airport and Airway Trust Fund, the Inland Waterways Trust Fund, and the Harbor Maintenance Trust Fund from being counted as new budget authority, outlays, receipts, or deficit or surplus for purposes of the Federal budget as submitted by the President, the congressional budget, or the Balanced Budget and Emergency Deficit Control Act of 1985 . Exempts such trust funds from any general statutory budget outlays limitation.

And (2) the net aviation receipts at the close of such year.
