An employee pays 6.2% of OASDI (Social Security) wages until that limit is reached, and the employer pays a separate 6.2% match. At or above the base, each side contributes a maximum of $11,439 for the year. Medicare withholding does not stop at this point because Medicare has no earnings cap.
What the Social Security payroll tax cap limits
The cap is an annual limit on wages subject to the Old-Age, Survivors, and Disability Insurance (OASDI) tax. It applies to the worker’s covered earnings for the calendar year, not to each paycheck, month, or employer as a separate national limit.

The Social Security Administration (SSA) also uses the same contribution and benefit base when determining which earnings count in a worker’s benefit computation. Wages above the base are not subject to OASDI for that year and do not increase the earnings record used under the annual limit.
The limit applies to each worker’s OASDI-covered wages. It does not combine the employee’s tax with the employer’s tax into one shared ceiling. Each party has its own 6.2% obligation on the wages that are subject to Social Security tax.
#1 Best Overall
2026 employee and employer amounts
| Item | 2026 rule | Maximum at the wage base |
|---|---|---|
| Employee OASDI tax | 6.2% of covered wages up to $184,500 | $11,439 |
| Employer OASDI tax | 6.2% of the employee’s covered wages up to $184,500 | $11,439 |
| Combined employee and employer OASDI | Two separate 6.2% shares | $22,878 |
The $11,439 employee figure is the most that can be withheld for Social Security from one employee’s covered wages when the worker reaches the 2026 base. The employer’s $11,439 is a business expense paid separately; it is not deducted from the employee’s paycheck.
How withholding builds during the year
With one employer, payroll generally tracks the employee’s year-to-date OASDI wages. The 6.2% employee withholding applies until those wages reach the annual base. The employer makes its matching calculation on the same covered wages.
Worker earning less than the base
An employee with $100,000 of OASDI-covered wages in 2026 has employee Social Security withholding of $6,200. The employer’s matching OASDI contribution is also $6,200. Because the worker has not reached the annual base, Social Security withholding continues on later covered wages paid during the year.

Worker earning more than the base
If an employee receives $200,000 of covered wages from one employer, only the first $184,500 is subject to OASDI. The employee’s annual Social Security withholding reaches $11,439, and the employer’s matching contribution reaches the same amount. The final $15,500 of wages is above the OASDI base, so Social Security tax does not apply to that portion.

Payroll systems may reach the limit partway through a pay period. The exact paycheck in which withholding changes depends on the wages paid and the employer’s payroll schedule, but the annual total cannot exceed the applicable base for that employer’s covered wages.
How SSA sets the annual wage base
The cap is adjusted over time rather than chosen as a fixed dollar amount. For years after 1994, SSA’s formula starts with the $60,600 contribution and benefit base for 1994 and multiplies it by the ratio of the national average wage index for two years before the target year to the national average wage index for 1992.
SSA then rounds the calculated amount to the nearest $300. A hold-harmless rule prevents the new base from falling below the prior year’s base if the formula would otherwise produce a lower number.

For 2026, SSA used a 2024 national average wage index of 69,846.57 and a 1992 index of 22,935.42. The indexed calculation produced $184,548.71. Rounding to the nearest $300 results in the published 2026 contribution and benefit base of $184,500.
The formula means that a new year can bring a higher or, subject to the hold-harmless rule, no lower wage base. The amount is specific to the tax year, so an older pay stub or payroll table may show a different limit.
What changed from 2025 to 2026
| Tax year | Contribution and benefit base | Change from prior year |
|---|---|---|
| 2025 | $176,100 | |
| 2026 | $184,500 | $8,400 increase |
The 2026 increase means a high earner can have Social Security withholding on $8,400 more of covered wages than in 2025. At the 6.2% employee rate, that additional wage room represents as much as $520.80 of additional employee OASDI withholding for someone whose wages already exceeded both annual bases. The employer’s potential additional match is the same amount.
Employee and employer shares are separate
An employee’s paycheck shows only the employee share of OASDI. The employer does not deduct its matching contribution from the worker’s wages. For a worker who reaches the base, the employee’s Social Security withholding totals $11,439, while the employer pays another $11,439 to the government.
This distinction matters when reviewing total compensation or reconciling payroll records. A statement showing $11,439 withheld from the employee does not mean the employee paid the combined $22,878. The second half is the employer’s liability.
Rank #4
What happens when you have more than one job
Each employer must withhold Social Security tax from the wages that employer pays. Employers generally do not know the worker’s year-to-date wages from another job and do not stop withholding based on another employer’s payroll.
As a result, a worker with multiple employers can have combined employee withholding above the annual maximum even though each employer correctly withheld on its own wages. The employee can claim the excess employee withholding as a refund on the following year’s federal tax return, subject to the applicable filing rules.
Illustrative two-job example
Suppose one worker earns $120,000 from Employer A and $120,000 from Employer B in 2026. Each employer withholds 6.2% on its own $120,000 of wages, or $7,440. Total employee withholding is therefore $14,880. Compared with the $11,439 annual maximum, the excess is $3,441. The employers’ separate matching contributions do not become an employee refund; the refund issue concerns the employee’s excess withholding.
Because each employer calculates independently, an employee should not expect the second payroll department to know that the annual limit was reached at the first job. Keep the year-end wage and withholding statements from every employer and reconcile the combined employee OASDI withholding when preparing the tax return.

Social Security and Medicare use different rules
The Social Security cap is not a cap on all FICA taxes. Medicare’s Hospital Insurance (HI) tax has had no taxable maximum since 1994. Standard 2026 HI tax is 1.45% for the employee and 1.45% for the employer on Medicare-taxable wages, including wages above the Social Security base.
| Feature | OASDI (Social Security) | HI (Medicare) |
|---|---|---|
| 2026 employee rate | 6.2% | 1.45% |
| 2026 employer rate | 6.2% | 1.45% |
| Maximum taxable earnings | $184,500 for 2026 | No maximum earnings amount |
| Employee maximum at the Social Security base | $11,439 | Withholding continues above the Social Security base |
When Social Security withholding disappears from a paycheck after the worker reaches the OASDI base, Medicare withholding should generally remain on later Medicare-taxable wages. A pay stub can therefore show zero or reduced Social Security tax while still showing Medicare tax.
How to read a paycheck near the cap
Use the year-to-date columns rather than judging the limit from one paycheck. The relevant checks are:
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Confirm the calendar year shown on the statement, because the wage base resets for a new year.
- Review year-to-date Social Security wages, not just gross pay. Some forms of compensation may not be covered in the same way as ordinary wages.
- Compare year-to-date employee Social Security withholding with the annual maximum for that tax year.
- Check Medicare withholding separately; reaching the OASDI base does not end Medicare tax.
- If you changed jobs or held concurrent jobs, add the Social Security wages and employee withholding reported by every employer.
If a single employer appears to continue withholding after that employer’s covered wages have reached the annual base, ask the payroll department to review the year-to-date wage and tax totals. If the apparent excess results from multiple employers, the employers may each have followed the required separate withholding rule, leaving the employee to reconcile the excess on the tax return.
Why the cap matters beyond one paycheck
The wage base determines two related things for the year: how much OASDI tax can be imposed on covered earnings and how much of those earnings is considered in the Social Security benefit formula. Earning above the base can increase take-home pay later in the year because OASDI withholding stops for that employer, but those excess wages are outside the annual earnings limit used for benefit computations.
The limit is individual and annual. It is not a household ceiling, a combined employee-employer ceiling, or a lifetime limit. A new calendar year begins a new withholding calculation under that year’s published base.
Common mistakes to avoid
- Treating $184,500 as a combined FICA cap. It limits OASDI wages only; Medicare has no earnings maximum.
- Subtracting the employer match from the employee’s limit. The two 6.2% shares are separate obligations.
- Expecting one employer to coordinate with another. Each employer withholds on its own wages, so combined withholding can exceed the annual employee maximum.
- Using the 2025 base for 2026 payroll. The base rose from $176,100 to $184,500.
- Assuming the cap applies to every payroll tax. The rule is specific to OASDI and does not end standard Medicare withholding.
- Confusing a refund with an employer correction. Multiple-employer excess withholding is addressed through the employee’s tax return; the employers’ matching amounts are separate.
Official figures and annual updates
SSA publishes the contribution and benefit base, OASDI and HI rates, maximum contributions, historical amounts, and the formula used for annual determinations. Its January 2, 2026 FAQ identifies the 2026 taxable maximum and explains the Medicare distinction. Because the base can change each year, use the SSA amount for the specific tax year shown on the paycheck or tax form when checking withholding.
