What it does
This bill makes permanent a tax rule that allows businesses to deduct depreciation, amortization, and depletion when calculating limits on how much business interest they can deduct. The rule was set to expire after 2021; this bill removes that expiration date, letting businesses use this deduction indefinitely going forward.
Why we flagged it
The bill's sole operative mechanism is to make permanent a business tax deduction that was scheduled to sunset. It is a straightforward tax-code amendment benefiting capital-intensive businesses, with no public-interest framing or offsetting revenue measure.
What the text implies
- The bill does not specify which industries or business sizes benefit most; capital-intensive sectors (manufacturing, real estate, energy) will capture disproportionate value relative to service or labor-intensive businesses.
- No revenue offset or pay-for is included; the permanent extension increases the federal deficit unless offset elsewhere in the budget.
- The effective date (taxable years after Dec. 31, 2021) means the bill retroactively codifies what was already in effect; the true cost is the permanent loss of future revenue that would have been collected after the original 2021 sunset.

Who it affects
The bill permanently extends a tax deduction that reduces business tax liability without a corresponding public benefit or revenue offset. The cost is borne by the general taxpayer base, which must compensate for foregone federal revenue. Businesses—particularly capital-intensive ones—are the primary beneficiaries.
Who stands to gain
- capital-intensive businesses (manufacturing, real estate, energy, infrastructure)
- large corporations with significant depreciation/amortization schedules
- private equity and real estate investment firms
