What changed
Under the 2022 to 2024 rules, adjusted taxable income was computed without adding back depreciation, amortization or depletion, which shrank the 30% limit for capital-heavy businesses. The Form 8990 instructions confirm those add-backs return for tax years beginning after 2024.
Businesses with average annual gross receipts of $31 million or less for 2025 remain exempt from the limit, subject to the usual tax shelter exclusion.
