The inflation adjusted items for the Code sections set forth in section 3 of this revenue procedure are generally determined by reference to§   1(f). To the extent amendments to the Code are enacted for 2024 after November 9, 2023, taxpayers should consult additional guidance to determine whether these adjustments remain applicable for 2024.   
     
 SECTION 2. CHANGES.01 For calendar years beginning on or after January 1, 2023,§ 13601(a)(2) of Public Law 117-169, 136 Stat. 1818 (August 16, 2022), commonly known as the Inflation Reduction Act of 2022 (IRA), reinstates the Hazardous Substance Superfund financing rate for crude oil received at a United States refinery and petroleum products entered into the United States for consumption, use, or warehousing under§ 4611.

 SECTION 3. 2024 ADJUSTED ITEMS.01 Tax Rate Tables. For taxable years beginning in 2024, the tax rate tables under§ 1 are as follows:   
     
TABLE 1 - Section 1(j)(2)(A) - Married Individuals Filing Joint Returns and Surviving Spouses   
     
       
   
TABLE 2 - Section 1(j)(2)(B) - Heads of Households
   
       
   
TABLE 3 - Section 1(j)(2)(C) - Unmarried Individuals (other than Surviving Spouses and Heads of Households)

TABLE 5 - Section 1(j)(2)(E) - Estates and Trusts.02 Unearned Income of Minor Children Subject to the "Kiddie Tax". For taxable years beginning in 2024, the amount in§ 1(g)(4)(A)(ii)(I), which is used to reduce the net unearned income reported on the child's return that is subject to the "kiddie tax," is $1,300. This $1,300 amount is the same as the amount provided in§ 63(c)(5)(A), as adjusted for inflation. The same $1,300 amount is used for purposes of§ 1(g)(7) to determine whether a parent may elect to include a child's   gross    income    in    the    parent's    gross    income and to calculate the "kiddie tax." For example, one of the requirements for the parental election is that a child's gross income is more than the amount referenced in§ 1(g)(4)(A)(ii)(I) but less than 10 times that amount; thus, a child's gross income for 2024 must be more than $1,300 but less than $13,000..03 Maximum Capital Gains Rate (§1(h),§1(j)(5)). For taxable years beginning in 2024, the maximum zero rate amounts and maximum 15 percent rate amounts under§ 1(j)(5)(B), as adjusted for inflation, are as follows:.04 Adoption Credit.

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).
