IRS Provides Tax Inflation Adjustments for Tax Year 2024
The IRS recently announced the annual inflation adjustments for more than 60 tax provisions for tax year 2024, including the tax rate schedules and other tax changes. Revenue Procedure 2023-34 provides detailed information about these annual adjustments.
New for 2024
Starting in calendar year 2023, the Inflation Reduction Act reinstates the Hazardous Substance Superfund financing rate for crude oil received at U.S. refineries and petroleum products that entered into the United States for consumption, use or warehousing. The tax rate is the sum of the Hazardous Substance Superfund rate and the Oil Spill Liability Trust Fund financing rate. For calendar years beginning in 2024, the Hazardous Substance Superfund financing rate is adjusted for inflation. For calendar year 2024, crude oil or petroleum products entered after Dec. 31, 2016, will have a tax rate of $0.26 cents a barrel.
