AIMM Act

This bill would change how businesses figure out the cap on their tax write‑off for interest they pay on loans. It would permanently let companies include certain non-cash costs—like depreciation, amortization, and depletion—when calculating their income for this limit. That usually raises the cap, so more of a business’s interest costs could be deducted from taxes.

It would apply starting with the 2022 tax year, and going forward, making this approach permanent rather than temporary.

• Who is affected: Businesses that deduct interest on loans.
• What changes: Depreciation, amortization, and depletion can be counted when setting the interest deduction limit, which can increase how much interest is deductible.
• When: Applies to tax years beginning after December 31, 2021 (starting with 2022) and is permanent.
