Key Takeaways
- The 2027 Social Security wage base increases to $192,300, affecting payroll costs for employers with high earners.
- Employers should factor the wage base into their 2027 payroll budgets, as it increases Social Security tax liability.
- Social Security tax for employers remains at 6.2%, while Medicare tax continues to apply without a wage cap.
- Self-employed individuals must pay Social Security and Medicare taxes through self-employment tax, which differs from payroll withholding.
- Employers must plan for payroll costs by identifying affected employees and updating payroll systems to reflect the new wage base.
Employers with highly compensated employees could see payroll costs increase again in 2027. The 2027 Social Security wage base is $192,300, up from $184,500 for 2026, according to the figures provided for this article. That means more of an employee’s compensation will be subject to Social Security tax next year.
For business owners, the change is worth factoring into 2027 payroll budgets, particularly when a company has employees earning above the 2026 limit.
What is the Social Security wage base?
The Federal Insurance Contributions Act, commonly called FICA, funds Social Security and Medicare through payroll taxes paid by employees and employers.
Social Security tax applies only to wages up to an annual limit. That limit is the Social Security wage base. Medicare tax works differently because there is no comparable wage cap.
For 2027, the standard FICA rates remain:
- Social Security: 6.2% for the employee and 6.2% for the employer, up to the wage base
- Medicare: 1.45% for the employee and 1.45% for the employer on covered wages
- Additional Medicare Tax: An additional 0.9% employee tax may apply above applicable thresholds
Employers are responsible for withholding employees’ portions of these taxes, paying the employer share and meeting applicable federal payroll tax deposit and reporting requirements.
How the 2027 Social Security wage base affects payroll costs
With the 2027 Social Security wage base set at $192,300, an employee who earns at least that amount can have up to $11,922.60 in Social Security tax withheld:
$192,300 × 6.2% = $11,922.60
The employer generally contributes the same maximum Social Security amount for an employee whose wages reach the limit.
Compared with the $184,500 wage base provided for 2026, an additional $7,800 of wages is subject to Social Security tax in 2027. At the 6.2% rate, that represents up to $483.60 more in employer Social Security tax per employee who earns at least the 2027 wage base.
For companies with several employees above the limit, that difference can become meaningful when building next year’s compensation and payroll budget.
Medicare tax works differently
The Social Security wage base does not limit Medicare tax. The regular 1.45% Medicare tax continues to apply to covered wages even after an employee exceeds $192,300.
Employers also have responsibilities related to the 0.9% Additional Medicare Tax. Employers generally must begin withholding the additional tax when wages paid to an employee exceed $200,000 during the calendar year, regardless of the employee’s filing status.
An important distinction is that the employer does not match the 0.9% Additional Medicare Tax.
Individual liability for the Additional Medicare Tax can depend on filing status and combined income. Employees may therefore need to consider their own circumstances separately from the employer’s withholding requirement.
What self-employed individuals should know
Business owners who are self-employed generally pay Social Security and Medicare taxes through the self-employment tax rather than employee payroll withholding.
The Social Security portion of self-employment tax is 12.4%, subject to the applicable Social Security wage base and coordination with any wages subject to Social Security tax. The regular Medicare portion is 2.9% and is not subject to the Social Security wage base.
The 0.9% Additional Medicare Tax may also apply when applicable earnings exceed the statutory threshold.
Because self-employment tax calculations can be affected by other wages and filing status, owners with multiple sources of earned income should review their individual circumstances when planning estimated tax payments.
What happens when an employee has more than one job?
The annual Social Security limit applies to an employee, but an employer generally considers only the wages that employer pays when determining when to stop withholding Social Security tax.
For example, an employee might earn wages from two unrelated employers and have Social Security tax withheld by both, even when the combined wages exceed the annual wage base.
That can result in excess Social Security tax withholding. When that happens because the employee worked for multiple employers, the employee may generally claim the allowable excess as a credit on an individual federal income tax return.
An employer should not stop Social Security withholding simply because an employee says wages from another employer have already caused them to reach the annual limit.
A look at how the wage base has changed
The Social Security wage base has increased substantially over time. When Social Security payroll taxes began in 1937, the wage base was $3,000. It remained at that level through 1950.
More recent limits illustrate how much the taxable wage ceiling has changed:
- 1980: $25,900
- 2020: $137,700
- 2025: $176,100
- 2026: $184,500
- 2027: $192,300
Annual changes matter most to employers with higher-paid employees because the increase can directly affect the amount of Social Security tax the business pays.
Start planning for 2027 payroll costs
The 2027 Social Security wage base is more than an annual payroll update. For employers with compensation above the wage base, the increase can affect payroll budgets and projections for the coming year.
Before 2027 begins, consider:
- Identifying employees whose annual compensation is expected to approach or exceed $192,300
- Incorporating the higher wage base into payroll tax projections
- Reviewing compensation and payroll assumptions used in the 2027 budget
- Making sure payroll systems reflect the new limit when it takes effect
- Reviewing payroll tax considerations for owners who have both wages and self-employment income
