The Social Security Administration (SSA) recently announced that the “wage base” for computing Social Security tax will increase for 2024 to $168,600. This is up from $160,200 for 2023.
Federal law limits the amount of earnings that are subject to the Old-Age, Survivors, and Disability Insurance (OASDI) tax in a given year. This threshold, referred to as the Social Security wage base, means that if you earn more than $168,600 in 2024, you won’t pay OASDI tax on the amount above that.
Workers will continue to be taxed at the 6.2% OASDI tax rate on wages up to this base amount.
Adding It Up
In addition, employees must pay Medicare tax on all wages. For 2024, an employee will pay:
- 6.2% Social Security tax on the first $168,600 of wages, making the maximum tax $10,453.20 (6.20% times $168,600), plus
- 1.45% Medicare tax on the first $200,000 of wages ($250,000 for joint returns; $125,000 for married taxpayers filing a separate return), plus
- 2.35% Medicare tax (regular 1.45% Medicare tax plus 0.9% additional Medicare tax) on all wages in excess of $200,000 ($250,000 for joint returns; $125,000 for married taxpayers filing a separate return).
The Social Security and Medicare tax rates for self-employed individuals are doubled. However, these taxpayers can deduct half of these employment tax payments on their federal income tax returns to arrive at adjusted gross income.
So for 2024, self-employed people will pay:
- 12.4% Social Security tax on the first $168,600 of self-employment income, plus
- 2.90% Medicare tax on the first $200,000 of self-employment income ($250,000 of combined self-employment income on a joint return and $125,000 on a separate return) plus
- 3.8% (2.90% regular Medicare tax plus 0.9% additional Medicare tax) on all self-employment income in excess of $200,000 ($250,000 of combined self-employment income on a joint return and $125,000 for married taxpayers filing a separate return).
The SSA also announced that Social Security and Supplemental Security Income (SSI) benefits will increase by 3.2% in 2024 — significantly less than the 8.7% SSI benefits increase in 2023. The average monthly Social Security benefit will increase from $1,848 to $1,907, and the maximum federal SSI monthly payment to an individual will increase from $914 to $943 in 2024. The maximum federal SSI monthly payment to a couple will increase from $1,371 to $1,415 in 2024.
