01 · The brief
Plain-English summaryWhat this bill actually does

The bill, titled the American Innovation and Jobs Act, amends the Internal Revenue Code to (1) restore immediate expensing (current deduction) for research and experimental expenditures under section 174 (with an effective date back to amounts paid or incurred in taxable years beginning after December 31, 2021), (2) expand and phase up the cap and eligibility rules for the refundable research credit available to new and small businesses (section 41(h)), including raising the refundable cap over time and lengthening the startup eligibility window, and (3) change certain calculations and election rules for qualified small businesses’ research credits (including specified rate and averaging changes). Several conforming and technical amendments to sections 41, 280C, 3111, and related provisions are included.

Why people may split

Revenue impact vs. growth incentive: liberals stress offsets; conservatives prioritize tax relief.
