The Congressional Budget Office (CBO) is in the process of preparing a cost estimate for the current version of H.R. 5376, the Build Back Better Act (Rules Committee Print 117-18 incorporating a manager’s amendment by Congressman Yarmuth). CBO has provided technical assistance to committees as they developed their proposals for various parts of the bill. The analysis of the many provisions is complicated, and CBO will provide a cost estimate for the entire bill as soon as practicable and possibly by November 19. CBO is releasing estimates for individual titles of bills as they are completed.
Update: The cost estimate is available here.
