2027 Social Security Tax Limit

The 2027 Social Security tax limit determines the maximum amount of earnings subject to Social Security payroll tax during 2027.

The Social Security Administration has projected a 2027 taxable maximum of $190,200 under the intermediate assumptions in its 2026 Trustees Report. This is a projection, not yet the final official 2027 wage base.

For comparison, the 2026 Social Security taxable maximum is $184,500.

2027 Social Security Tax Limit

The projected 2027 Social Security wage base is $190,200.

The taxable maximum is also called the Social Security wage base, contribution and benefit base, or maximum taxable earnings.

What Is the Social Security Tax Limit?

The Social Security tax limit is the maximum amount of wages subject to the 6.2% Social Security payroll tax.

Once an employee reaches the annual taxable maximum, additional wages are no longer subject to the 6.2% Social Security tax for that calendar year.

Medicare tax works differently because Medicare has no comparable wage base limit.

2027 Social Security Tax Rate

The Social Security payroll tax rate is 6.2% for employees.

Employers generally pay a matching 6.2%.

This creates a combined Social Security payroll tax rate of 12.4%.

For 2027, assuming the current tax rate remains unchanged, the maximum employee Social Security tax on $190,200 of taxable earnings would be:

$190,200 × 6.2% = $11,792.40

The employer would generally pay another $11,792.40.

2027 Social Security Tax Limit for Employees

An employee earning $190,200 or more in 2027 would reach the projected Social Security taxable maximum.

The employee’s Social Security tax would therefore be limited to approximately $11,792.40 for the year.

Example: An employee earns $250,000 in 2027. Social Security tax would generally apply only to the first $190,200 of wages.

The remaining $59,800 would not be subject to the 6.2% Social Security payroll tax.

2027 Social Security Tax Limit for Self-Employed Workers

Self-employed individuals generally pay both the employee and employer portions of Social Security tax through self-employment tax.

The combined Social Security tax rate is 12.4%.

Using the projected $190,200 wage base, the maximum Social Security portion would be approximately:

$190,200 × 12.4% = $23,584.80

The actual self-employment tax calculation is more complicated because self-employment income is generally adjusted before the Social Security portion is calculated.

2027 Social Security Wage Base

The Social Security wage base changes each year.

The annual adjustment reflects changes in average wages.

The 2026 wage base increased to $184,500.

The 2026 Trustees Report projects the 2027 wage base at $190,200 under its intermediate assumptions.

Why Does the Social Security Tax Limit Increase?

The Social Security taxable maximum is generally adjusted based on changes in the national average wage index.

This allows the taxable maximum to increase as wages rise.

The projected 2027 increase from $184,500 to $190,200 represents an increase of $5,700.

That is approximately a 3.1% increase.

2026 vs. 2027 Social Security Tax Limit

The difference between the two years is:

$190,200 − $184,500 = $5,700

A worker earning at least the taxable maximum could therefore have an additional $5,700 of wages subject to Social Security tax in 2027.

At 6.2%, the additional employee Social Security tax would be:

$5,700 × 6.2% = $353.40

When Will the Official 2027 Social Security Wage Base Be Announced?

The $190,200 figure is currently a projection from the 2026 Social Security Trustees Report.

The final 2027 taxable maximum is determined through the annual automatic adjustment process.

The official figure is expected to be announced later in 2026 along with the other annual Social Security changes.

This means taxpayers should distinguish between the projected 2027 Social Security tax limit of $190,200 and the final official amount.

What Happens When You Reach the Social Security Wage Base?

Once an employee reaches the annual Social Security wage base, the employer generally stops withholding the 6.2% Social Security tax from additional wages for that year.

Medicare tax continues.

This can result in a noticeable increase in take-home pay later in the year for high-income employees.

Example: Employee Reaches the Wage Base in September

Suppose an employee earns enough to reach $190,200 in September 2027.

Once the employee reaches the Social Security taxable maximum, the 6.2% Social Security withholding generally stops for the remainder of the year.

However, Medicare tax continues to be withheld from subsequent wages.

Social Security Tax vs. Medicare Tax

Social Security and Medicare taxes are both payroll taxes, but they have different limits.

Higher-income workers may also owe the Additional Medicare Tax.

2027 Additional Medicare Tax

The Additional Medicare Tax is separate from the Social Security wage base.

The Additional Medicare Tax rate is 0.9%.

Employers generally begin withholding this additional tax when an employee’s wages from that employer exceed $200,000 during the year.

The taxpayer’s final liability depends on filing status.

The thresholds are:

The Additional Medicare Tax thresholds are not the same as the Social Security taxable maximum.

Does Medicare Tax Stop at the Social Security Limit?

No.

This is one of the most common misunderstandings about payroll taxes.

When an employee reaches the Social Security wage base, Social Security withholding stops.

Medicare withholding continues on all covered wages.

Example: An employee earns $250,000.

Social Security tax generally applies only up to the $190,200 projected 2027 wage base.

Medicare tax generally applies to the entire $250,000.

2027 Social Security Tax Limit and High-Income Workers

The taxable maximum is particularly important for people with high salaries.

Workers earning significantly more than the wage base will pay the maximum Social Security payroll tax during the year.

Their additional earnings above the wage base are not subject to the regular 6.2% Social Security tax.

However, those earnings can still be subject to Medicare taxes and federal income tax.

Multiple Jobs and the Social Security Tax Limit

People who work for more than one employer may have each employer withhold Social Security tax.

Unlike the Additional Medicare Tax withholding rules, Social Security has an annual combined wage limit for the employee.

If too much Social Security tax is withheld because of multiple employers, the excess can generally be claimed as a credit on the federal tax return.

Example: Two Employers

Suppose a worker earns:

• $120,000 from Employer A
• $100,000 from Employer B

Total wages are:

$220,000

Using the projected 2027 wage base of $190,200, only $190,200 of combined wages would generally be subject to Social Security tax.

If both employers withheld Social Security tax on the full wages, the employee could have excess Social Security withholding.

The excess can generally be claimed when filing the federal tax return.

Social Security Tax for Married Couples

The Social Security wage base applies separately to each worker.

A married couple does not share one $190,200 Social Security tax limit.

Each spouse has a separate taxable maximum.

Example: Both spouses earn $200,000 in 2027.

Each spouse would reach the projected $190,200 taxable maximum.

The couple could therefore have up to $380,400 of combined wages subject to Social Security tax.

Social Security Tax Limit and Retirement Benefits

The taxable maximum is important not only because it limits payroll taxes but also because Social Security benefits are based partly on a worker’s earnings history.

Earnings subject to Social Security taxes can be used in calculating future retirement benefits.

However, earnings above the annual taxable maximum generally do not increase Social Security benefits through the regular benefit formula.

Does Earning More Than the Wage Base Increase Social Security Benefits?

Not through the regular earnings record for that year.

Once earnings reach the taxable maximum, additional earnings for that year are not counted as Social Security-covered earnings above the maximum.

Example: A worker earns $500,000 in 2027.

For Social Security purposes, earnings are generally credited only up to the applicable taxable maximum.

The additional earnings above the maximum do not produce additional Social Security credits for that year.

Social Security Tax Limit and Maximum Benefits

A worker seeking the maximum possible Social Security retirement benefit generally needs a long history of earnings at or above the taxable maximum.

However, simply earning more than the taxable maximum in one year does not produce a larger benefit for that year.

Social Security benefits are based on a worker’s earnings history and claiming age.

2027 Social Security Tax Limit for Seniors

Older workers who continue working remain subject to Social Security payroll taxes on wages covered by Social Security.

Age does not eliminate the Social Security payroll tax from wages.

A worker who is already receiving Social Security benefits can still pay Social Security taxes on employment income.

Working While Receiving Social Security

Some retirees continue working while collecting Social Security benefits.

Their wages can be subject to Social Security and Medicare payroll taxes.

The earnings test may also apply if the worker is below full retirement age.

These are separate rules from the Social Security taxable maximum.

Social Security Tax Limit and the Earnings Test

The Social Security earnings test determines whether benefits may be temporarily reduced when someone works while receiving Social Security before reaching full retirement age.

The earnings test is not the same as the Social Security wage base.

A person can earn more than the earnings-test limit and have benefits affected even though the Social Security taxable maximum is much higher.

Social Security Taxable Maximum vs. Earnings Limit

These two terms are often confused.

The taxable maximum determines how much wages are subject to Social Security payroll tax.

The earnings limit determines how much a person can earn while receiving Social Security before full retirement age without having benefits withheld under the earnings test.

They serve completely different purposes.

Social Security Tax and 401(k) Contributions

401(k) contributions generally do not reduce wages subject to Social Security tax.

This distinction matters for payroll taxes and federal income taxes.

A traditional 401(k) contribution can generally reduce federal taxable income, but it generally does not reduce Social Security or Medicare wages.

Example: An employee earns $200,000 and contributes $20,000 to a traditional 401(k).

The employee’s federal income-taxable wages may be reduced by the contribution, but Social Security wages generally remain $200,000.

Social Security Tax and Health Insurance

Employee health insurance premiums paid through certain employer plans can have different payroll-tax treatment.

The specific treatment depends on the plan type and how the premiums are paid.

Employees should review their W-2 when determining Social Security wages.

Social Security Tax and Bonuses

Bonuses generally count as wages for Social Security tax purposes.

A bonus can therefore cause an employee to reach the annual taxable maximum sooner.

Example: An employee has earned $175,000 during 2027 and receives a $30,000 bonus.

Only the portion needed to reach the taxable maximum would generally be subject to Social Security tax.

Using the projected $190,200 limit, approximately $15,200 of the bonus would remain subject to Social Security tax.

Social Security Tax and Overtime

Qualifying overtime compensation is generally still subject to Social Security payroll taxes.

Recent federal tax legislation created a federal income tax deduction for certain qualified overtime compensation, but that deduction does not generally eliminate Social Security payroll taxes on the underlying wages.

This distinction is important for workers earning substantial overtime.

Social Security Tax and Self-Employment

Self-employed taxpayers pay Social Security tax through the self-employment tax system.

The Social Security portion is generally 12.4%.

The taxable maximum applies to the Social Security portion of self-employment income.

The Medicare portion of self-employment tax does not have the same wage base limit.

Example: Self-Employed Worker

Suppose a self-employed taxpayer has sufficient net earnings to reach the projected 2027 Social Security wage base.

The Social Security portion of self-employment tax would generally be limited to:

$190,200 × 12.4% = $23,584.80

The actual tax calculation can differ because self-employment earnings are generally subject to a statutory adjustment before the Social Security and Medicare taxes are calculated.

Social Security Tax Limit and W-2 Forms

Employees can find their Social Security wages and Social Security tax withheld on Form W-2.

The relevant information generally appears in:

• Box 3 – Social Security wages
• Box 4 – Social Security tax withheld

These amounts can help taxpayers determine whether the correct amount of Social Security tax was withheld.

What Happens If Too Much Social Security Tax Is Withheld?

Excess Social Security tax can sometimes occur when a taxpayer has multiple employers.

The excess may generally be claimed as a credit on the federal income tax return.

Employees with one employer generally do not need to calculate an excess withholding simply because they earned more than the wage base. The employer normally stops Social Security withholding once the employee reaches the annual limit.

2027 Social Security Tax Limit and Federal Income Tax

The Social Security wage base is separate from federal income tax brackets.

A taxpayer can earn more than the Social Security taxable maximum and still owe federal income tax on the additional earnings.

There is no equivalent federal income tax wage cap.

Common Social Security Tax Limit Mistakes

One common mistake is assuming Social Security tax applies to every dollar of wages.

Another is assuming Medicare tax stops at the Social Security wage base.

Other common mistakes include:

• Confusing the taxable maximum with the earnings test
• Forgetting that each spouse has a separate wage base
• Overlooking multiple-employer withholding
• Assuming 401(k) contributions reduce Social Security wages
• Confusing Social Security taxes with federal income taxes
• Assuming the 2027 projected amount is already final

2027 Social Security Tax Limit at a Glance

The $190,200 figure is the intermediate projection in the 2026 Social Security Trustees Report. The final official 2027 taxable maximum will be determined through the annual adjustment process.

2026 vs. 2027 Social Security Tax Limit

The projected increase in the wage base is $5,700.

The corresponding increase in maximum employee Social Security tax would be approximately $353.40.

Electronic Filing Recommendation 💻

Electronic filing makes it easier to report wages, Social Security tax withholding, and other payroll information accurately.

Tax software can use information from Form W-2 to calculate the federal tax return and identify potential excess Social Security tax withholding when applicable.

Electronic filing can provide:

• Faster processing
• Improved filing accuracy
• Automatic calculations
• Direct deposit availability
• Faster filing confirmation
• Easier recordkeeping

Workers with multiple employers should carefully review Box 3 and Box 4 of their W-2 forms before filing.

Bottom Line

The 2027 Social Security tax limit is currently projected to be $190,200, compared with the official 2026 limit of $184,500.

At the 6.2% employee tax rate, a worker earning at least $190,200 would have approximately $11,792.40 withheld for Social Security tax during 2027. Employers would generally contribute a matching $11,792.40.

The projected $190,200 limit is not the same as the Medicare tax limit. Medicare tax generally continues on all covered wages, while Social Security tax stops once the annual taxable maximum is reached.

The wage base is also separate from the Social Security earnings test, which determines whether benefits can be temporarily reduced when someone works while receiving Social Security before full retirement age.

For workers earning high salaries, married couples with two incomes, self-employed individuals, and seniors who continue working, understanding the Social Security taxable maximum can help with paycheck and retirement tax planning.
