Social Security wage base 2027: $192,300, and the most Social Security tax you can pay

What is the Social Security wage base for 2027?

The Social Security wage base for 2027 is $192,300. The Social Security Administration (SSA) announced it on October 14, 2026, in the same release as the 3.6% cost-of-living adjustment (COLA) for benefits. It is $7,800 higher than the 2026 base of $184,500.

The wage base, also called the taxable maximum or contribution and benefit base, is the most earnings per year that are subject to the 6.2% Social Security tax. At $192,300, the maximum employee tax for 2027 is $11,922.60, up $483.60 from $11,439.00 in 2026, and the employer pays the same (SSA, Contribution and Benefit Base). The current-year rules are covered on our Social Security wage base page.

When does the 2027 limit take effect?

The 2027 Social Security tax limit applies to wages paid on or after January 1, 2027. What counts is the date wages are paid, not when they were earned. A paycheck for late-December 2026 work that is paid on January 8, 2027 counts toward the 2027 limit.

Employers need the new base in their payroll systems before the first pay date of 2027. Medicare tax is unaffected: it has no wage base, so 1.45% applies to every dollar of wages in both years (see Medicare tax rate).

How was the 2027 taxable maximum calculated?

The taxable maximum is set by a formula in the Social Security Act, not by Congress each year. SSA explains the method on its Contribution and Benefit Base Determination page: the base for a year equals the 1994 base of $60,600 multiplied by the ratio of the national average wage index (AWI) from two years earlier to the AWI for 1992, rounded to the nearest multiple of $300.

Two safeguards come with the formula. The base is never reduced, even if average wages fall. And the formula applies only if a COLA takes effect for December of the year the determination is made. When there is no COLA, the base stays where it was.

The 2027 calculation, step by step

1. Start with the 1994 base: $60,600.
2. Multiply by the 2025 AWI of 72,800.33 and divide by the 1992 AWI of 22,935.42.
3. The result is $192,353.14.
4. Round to the nearest $300: $192,300.
5. Because $192,300 is higher than the 2026 base of $184,500 and a COLA of 3.6% takes effect for December 2026, the 2027 base became $192,300.

The 2025 AWI is 4.23% higher than the 2024 AWI of 69,846.57, which is what drove the $7,800 increase. The 2026 base came from the same steps: $60,600 times 69,846.57 divided by 22,935.42 gave $184,548.71, rounded to $184,500.

Social Security wage base history, 2017 to 2027

The table below lists the official taxable maximums from SSA, including the newly announced 2027 figure, with the maximum employee tax at 6.2%. The years 2010, 2011 and 2016, not all shown here, had no COLA, which is why the base did not move in those years ($106,800 for 2009 through 2011 and $118,500 for 2015 and 2016).

What is the max Social Security tax for 2027?

The max Social Security tax for 2027 is $11,922.60 for an employee, and the employer pays the same amount on top. A self-employed person pays both halves, 12.4%, on net self-employment earnings up to the base, for a maximum of $23,845.20.

These caps apply to the Social Security part only. Medicare tax of 1.45% (2.9% for the self-employed) has no cap, and the 0.9% Additional Medicare Tax is withheld on wages over $200,000 whatever the wage base. If you budgeted for 2027 with the 2026 figure or an earlier projection, each $1,000 of extra base adds $62 of employee tax and $124 of self-employment tax.

How does the 2027 limit affect high earners?

Only people whose Social Security wages or self-employment earnings exceed $184,500 are affected. Anyone earning $184,500 or less pays 6.2% on every dollar in both years. Between $184,500 and $192,300, more of your pay is taxed in 2027; at $192,300 or more, an employee pays the full $483.60 extra.

• Employees above the cap: Social Security withholding continues for more pay periods before it stops. On a $240,000 salary paid in 26 equal checks of about $9,230.77, withholding now stops partway through the 21st check instead of the 20th.
• Self-employed people: Social Security tax is 12.4% of net self-employment earnings up to the base, and W-2 wages use up the base first, so the $7,800 increase can add up to $967.20 of self-employment tax for 2027. Our self-employment tax calculator shows the 2026 figure, and the self-employment tax rate page explains Schedule SE.
• Workers with two employers: each employer withholds up to the full $192,300, so combined withholding can exceed $11,922.60. The excess employee tax is claimed back as a credit on your 2027 return, filed in 2028, not by your employers.
• Future benefits: the same base caps the earnings SSA counts when it figures retirement benefits, so up to $192,300 of 2027 earnings is credited to your record.

What other Social Security figures change in 2027?

SSA announced the other 2027 amounts on the same day. They do not change how Social Security is taxed, but they matter for anyone who works while collecting benefits or who receives Supplemental Security Income (SSI).

The earnings test is not a tax. Benefits withheld under it are not lost: at full retirement age SSA recalculates your benefit to credit the months it withheld. Whether your benefits are taxable is a separate test, based on income and filing status, explained on our tax on Social Security benefits page. SSI payments are not taxable.

Planning notes for 2027

1. Keep using $184,500 for the rest of 2026 payroll and for 2026 Schedule SE and estimated tax worksheets.
2. Employers should load $192,300 into payroll systems before the first January 2027 pay date.
3. Self-employed people can now use $192,300 when sizing 2027 estimated payments. The first one is expected on April 15, 2027; see 2027 estimated tax due dates.
4. If you expect a large bonus paid in early January 2027, the 2027 base, not the 2026 base, applies to it.
5. Check our FICA tax guide for the combined employee and employer totals.
