Hazardous Substance Superfund Financing Rate
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.

See section 3.19 of this revenue procedure for the adjusted items relating to adoption assistance programs.
Child Tax Credit

Earned Income Credit
For taxable years beginning in 2024, the following amounts are used to determine the earned income credit under § 32(b). The “earned income amount” is the amount of earned income at or above which the maximum amount of the earned income credit is allowed.
The “threshold phaseout amount” is the amount of adjusted gross income (or, if greater, earned income) above which the maximum amount of the credit begins to phase out.
The “completed phaseout amount” is the amount of adjusted gross income (or, if greater, earned income) at or above which no credit is allowed.
The threshold phaseout amounts and the completed phaseout amounts shown in the table below for married taxpayers filing a joint return include the increase provided in § 32(b)(2)(B), as adjusted for inflation for taxable years beginning in 2024.
The threshold phaseout amounts and the completed phaseout amounts shown in the table below for taxpayers with all other filing statuses also apply to married taxpayers who are not filing a joint return and satisfy the special rules for separated spouses in § 32(d).

The instructions for the Form 1040 series provide tables showing the amount of the earned income credit for each type of taxpayer.

Items unaffected by indexing:
By statute, certain items that were indexed for inflation in the past are currently not adjusted.
- The personal exemption for tax year 2024 remains at 0, as it was for 2023. This elimination of the personal exemption was a provision in the Tax Cuts and Jobs Act.
- For 2024, as in 2023, 2022, 2021, 2020, 2019 and 2018, there is no limitation on itemized deductions, as that limitation was eliminated by the Tax Cuts and Jobs Act.
- The modified adjusted gross income amount used by taxpayers to determine the reduction in the Lifetime Learning Credit provided in § 25A(d)(2) is not adjusted for inflation for taxable years beginning after Dec. 31, 2020. The Lifetime Learning Credit is phased out for taxpayers with modified adjusted gross income in excess of $80,000 ($160,000 for joint returns).
2024 Standard Mileage Rate
The Internal Revenue Service issued the 2024 optional standard mileage rates used to calculate the deductible costs of operating an automobile for business, charitable, medical or moving purposes.
Beginning on Jan. 1, 2024, the standard mileage rates for the use of a car (also vans, pickups or panel trucks) will be:
- 67 cents per mile driven for business use, up 1.5 cents from 2023.
- 21 cents per mile driven for medical or moving purposes for qualified active-duty members of the Armed Forces, a decrease of 1 cent from 2023.
- 14 cents per mile driven in service of charitable organizations; the rate is set by statute and remains unchanged from 2023.
These rates apply to electric and hybrid-electric automobiles as well as gasoline and diesel-powered vehicles.
The standard mileage rate for business use is based on an annual study of the fixed and variable costs of operating an automobile. The rate for medical and moving purposes is based on the variable costs.
It is important to note that under the Tax Cuts and Jobs Act, taxpayers cannot claim a miscellaneous itemized deduction for unreimbursed employee travel expenses. Taxpayers also cannot claim a deduction for moving expenses, unless they are members of the Armed Forces on active duty moving under orders to a permanent change of station.
Taxpayers always have the option of calculating the actual costs of using their vehicle rather than using the standard mileage rates.
Taxpayers can use the standard mileage rate but generally must opt to use it in the first year the car is available for business use. Then, in later years, they can choose either the standard mileage rate or actual expenses.
Leased vehicles must use the standard mileage rate method for the entire lease period (including renewals) if the standard mileage rate is chosen.
Notice 2024-08 contains the optional 2024 standard mileage rates, as well as the maximum automobile cost used to calculate the allowance under a fixed and variable rate (FAVR) plan. In addition, the notice provides the maximum fair market value of employer-provided automobiles first made available to employees for personal use in calendar year 2024 for which employers may use the fleet-average valuation rule in or the vehicle cents-per-mile valuation rule.
