IRS Announces 2025 Inflation Adjustments; Social Security Benefits Up 2.5% for 2025

(Parker Tax Publishing October 2024)

The IRS announced the tax year 2025 annual inflation adjustments for more than 60 tax provisions, including the tax rate schedules and other tax changes. In addition, the Social Security Administration announced that benefits will increase by 2.5 percent in 2025 and that the amount of earnings subject to social security tax will be $176,100, up from $168,600 in 2024. Rev. Proc. 2024-40; 2025 Social Security Fact Sheet.

On October 22, the IRS announced the 2025 annual inflation adjustments for more than 60 tax provisions, including the tax rate schedules, the standard deduction, and other tax-related items. The 2025 adjustments generally apply to tax returns filed in 2026. If amendments to the Code are enacted for 2025 after October 22, 2024, the IRS advises taxpayers to consult additional guidance to determine whether such adjustments remain applicable for 2025.

Observation: The 2025 adjustments for several key items such as the standard deduction and the tax brackets represent an increase of approximately 2.7 percent over the 2024 amounts.

In addition, on October 10, the Social Security Administration (SSA) issued a press release announcing that, in January 2025, a 2.5 percent cost-of-living adjustment (COLA) will take effect with respect to social security and supplemental security income benefits. The SSA also announced that, for 2025, the maximum amount of an individual's earnings subject to social security tax is $176,100.

Below is a summary of (1) the key inflation adjusted numbers for 2025 from Rev. Proc. 2024-40 and (2) the 2025 COLA information from the Social Security 2025 Fact Sheet.

Taxable Income Subject to the Maximum Rates

For tax year 2025, the top tax rate is 37 percent for single taxpayers with incomes greater than $626,350 ($626,350 for heads of households, $751,600 for married couples filing jointly). The tax rates for income levels less than those are:

(1) 35 percent for incomes over $250,525 (single and married filing separately), $250,500 (head of household), and $501,050 (married couples filing jointly);

(2) 32 percent for incomes over $197,300 (single, head of household, and married filing separately) and $394,600 (married couples filing jointly);

(3) 24 percent for incomes over $103,350 (single, head of household, and married filing separately), and $206,700 (married couples filing jointly);

(4) 22 percent for incomes over $48,475 (single and married filing separately), $64,850 (head of household), and $96,950 (married couples filing jointly);

(5) 12 percent for incomes over $11,925 (single and married filing separately), $17,000 (head of household), and $23,850 (married couples filing jointly);

(6) the lowest rate is 10 percent for incomes of $11,925 or less (single and married filing separately), $17,000 or less (head of household), and $23,850 or less (married couples filing jointly).

The maximum estate and trust tax rate is 37 percent on income over $15,650.

Maximum Capital Gains Rate

For tax years beginning in 2025, the maximum zero capital gain tax rate amount is $96,700 in the case of a joint return or surviving spouse, $64,750 in the case of an individual who is a head of household, $48,350 in the case of any other individual (other than an estate or trust), and $3,250 in the case of an estate or trust. The maximum 15-percent capital gain tax rate amount is $600,050 in the case of a joint return or surviving spouse, $300,000 in the case of a married individual filing a separate return, $566,700 in the case of an individual who is the head of a household, $533,400 in the case of any other individual (other than an estate or trust), and $15,450 in the case of an estate or trust.

Unearned Income of Minor Children

For 2025, the amount in Code Sec. 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 $1,350. This $1,350 amount is the same as the amount provided in Code Sec. 63(c)(5)(A), as adjusted for inflation. The same $1,350 amount is used for purposes of Code Sec. 1(g)(7) in determining 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 Code Sec. 1(g)(4)(A)(ii)(I) but less than 10 times that amount. Thus, a child's gross income for 2025 must be more than $1,350 but less than $13,500 for a parent to make the election.

Standard Deduction Amounts

The standard deduction for married filing jointly is $30,000 for 2025. For single taxpayers and married individuals filing separately, the standard deduction is $15,000 for 2025, and for heads of households, the standard deduction is $22,500 for 2025.

The standard deduction amount under for an individual who may be claimed as a dependent by another taxpayer cannot exceed the greater of (1) $1,350, or (2) the sum of $450 and the individual's earned income.

For 2025, the additional standard deduction amount for the aged (i.e., age 65 or older) or the blind is $1,600. That additional standard deduction amount is increased to $2,000 if the individual is also unmarried and not a surviving spouse.

Itemized Deduction Limitation

As with 2024, there is no overall limitation on itemized deductions. The limitation on itemized deductions was eliminated by the Tax Cuts and Jobs Act of 2017 (TCJA) through 2025.

Personal Exemptions

As with 2024, no personal exemptions are allowed for 2025. Personal exemptions were eliminated by the TCJA through 2025.

The exemption for estates and trusts is $30,700. Under Code Sec. 55(b)(1), the excess taxable income above which the 28 percent AMT tax rate applies is $119,550 for married filing separately and $239,100 for all other taxpayers.

The AMT exemption begins to phase out at $626,350 for unmarried individuals other than surviving spouses and married individuals filing separate returns, $1,252,700 for married individuals filing joint returns and surviving spouses, and $102,500 for estates and trusts.

Earned Income Credit

The 2025 maximum earned income credit amount is $8,046 for taxpayers filing jointly who have three or more qualifying children, up from a total of $7,830 for 2024. The maximum credit for a taxpayer with no qualifying children is $649, up from $632 for 2024. Rev. Proc. 2024-40 has a table providing maximum credit amounts for other categories, income thresholds, and phase-outs.

For tax years beginning in 2025, the threshold amount under Code Sec. 199A(e)(2) is $394,600 for married filing joint returns, $197,300 for married filing separate returns, and $197,300 for all other returns.

The OASDI tax rate for wages paid in 2025 is set by statute at 6.2 percent for employees and employers, each. Thus, an individual with wages equal to or larger than $176,100 will contribute $10,918.20 to the OASDI program in 2025, and his or her employer will contribute the same amount. The OASDI tax rate for self-employment income in 2025 is 12.4 percent.

Dear Tax Professional,

My name is James Levey, and a few years back I founded a company named Kleinrock Publishing. I started Kleinrock out of frustration with the prohibitively high prices and difficult search engines of BNA, CCH, and RIA tax research products ... kind of reminiscent of the situation practitioners face today.

Now that Kleinrock has disappeared into CCH, prices are soaring again and ease-of-use has fallen by the wayside. The needs of smaller firms and sole practitioners are simply not being met.

To address the problem, I’ve partnered with a group of highly talented tax writers to create Parker Tax Publishing ... a company dedicated to the idea that comprehensive, authoritative tax information service can be both easy-to-use and highly affordable.

Our product, the Parker Tax Pro Library, is breathtaking in its scope. Check out the contents listing to the left to get a sense of all the valuable material you'll have access to when you subscribe.

Or better yet, take a minute to sign yourself up for a free trial, so you can experience first-hand just how easy it is to get results with the Pro Library!

Sincerely,

James Levey
