Social Security Wage Base 2027: Tax Stops at $192,300

The 2027 Social Security wage base is $192,300, the point where your paycheck stops paying Social Security tax. The Social Security Administration announced the figure on Oct. 14, 2026, and it caps the employee share at $11,922.60 for the year, so every paycheck after the cap gets bigger.

When does a $200,000 salary hit the cap?

Say you earn $200,000 in 2027 and get paid twice a month, so each check is $8,333.33 before taxes. Social Security takes 6.2% of each one, or $516.67, until your year-to-date wages reach $192,300. For this salary, that happens on the 24th paycheck, dated Dec. 31.

By the end of November, 22 checks add up to $183,333.33 in wages. That leaves $8,966.67 of room, so the whole Dec. 15 check is taxed at the full $516.67. Only $633.33 of the Dec. 31 check falls under the cap, so that check has $39.27 of Social Security tax.

This table shows the Social Security tax on each paycheck for this illustrative salary, assuming no pre-tax deductions that lower Social Security wages.

The last row holds the jump: take-home pay rises $477.40 with no raise behind it. Because the Dec. 15 check is a normal one, that is the whole December increase, and Social Security tax for the year totals $11,922.60. Swap in your own salary and pay schedule in the take-home pay calculator to see which check crosses the line.

The 2027 cap vs. 2026 in five numbers

The Social Security Administration's 2027 cost-of-living fact sheet, released Oct. 14, 2026, puts the wage base, which the agency calls the taxable maximum, at $192,300, up from $184,500 in 2026. That is a $7,800 increase, or about 4.2%. The agency's Contribution and Benefit Base page shows the cap tracks the national average wage index, a yearly measure of average U.S. pay.

Benefits follow a separate number, the 3.6% cost-of-living adjustment (COLA) announced the same day. That adjustment is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), a monthly inflation index from the Bureau of Labor Statistics.

Internal Revenue Service (IRS) Topic No. 751, Social Security and Medicare Withholding Rates, sets the Social Security rate at 6.2% for the employee and 6.2% for the employer, applied only up to the wage base. This table compares the 2026 and 2027 limits for employees and the self-employed.

The self-employed maximum of $23,845.20 is double the employee figure. A freelancer with no W-2 job, the wage form employers issue to employees, pays both the employee and employer halves.

For the $200,000 earner above, the higher cap means $483.60 more Social Security tax in 2027 than in 2026. In 2026, the cap landed one check earlier, on Dec. 15, and only $1,166.67 of that check was taxed, so December take-home rose $961.01, compared with $477.40 in 2027.

Does Medicare tax ever stop?

Medicare tax has no cap. Topic 751 sets it at 1.45% for you and 1.45% for your employer on every dollar of wages, so a $200,000 salary carries $2,900 in employee Medicare tax. Across 2026, that salary carried $14,339 in total employee Federal Insurance Contributions Act (FICA) tax, meaning Social Security plus Medicare. In 2027 the total is $14,822.60, and the entire $483.60 difference comes from the higher wage base.

IRS Topic No. 560, Additional Medicare Tax, adds 0.9% on wages above $200,000 for single filers, $250,000 for married couples filing jointly, and $125,000 for married people filing separately. Those thresholds are not adjusted for inflation. Your employer starts withholding the extra 0.9% once it pays you more than $200,000 in a calendar year, whatever your filing status.

At a $200,000 salary, the extra tax never applies, because it covers only wages above the threshold. At $210,000 from one employer, it adds $90 for the year.

What if two employers both withhold Social Security tax?

Each employer withholds as if it were your only one. Say Dana earns $120,000 at a hospital and $95,000 at a consulting firm in 2027. The hospital withholds $7,440 in Social Security tax and the firm withholds $5,890, for $13,330 in total.

Dana's combined wages of $215,000 pass the $192,300 cap, so the most she owes is $11,922.60. That leaves $1,407.40 withheld above the limit. IRS Topic No. 608, on excess Social Security tax withheld, treats that excess as a credit on her federal income tax return. It lowers her tax bill or adds to her refund when she files her 2027 return in 2028.

That credit has limits. It applies only when two or more employers withheld. If a single employer takes more than $11,922.60, that employer is the one to correct the overcollection. Changing jobs midyear counts as two employers, because the new payroll system starts its count at zero.

On the Medicare side, Dana owes a little more. Neither employer paid her more than $200,000, so neither withheld the 0.9%. As a single filer with $215,000 in wages, she owes $135 in Additional Medicare Tax on Form 8959, which leaves a net $1,272.40 coming back.

How the cap works for W-2 plus 1099 income

Self-employment tax runs 12.4% for Social Security and 2.9% for Medicare, applied to 92.35% of net self-employment earnings. The current IRS instructions for Schedule SE say W-2 wages subject to Social Security tax fill the wage base first. Only the room left under the cap gets the 12.4%.

Say Marcus earns $150,000 in W-2 salary in 2027, plus $80,000 in net profit from freelance work his clients report on Form 1099, the form for contractor pay. His self-employment earnings are $73,880 after the 92.35% step. The cap leaves $42,300 of room, so the Social Security part is $5,245.20. Medicare adds $2,142.52, for $7,387.72 in self-employment tax.

Without the W-2 credit, the Social Security part alone would be $9,161.12, so counting wages first saves Marcus $3,915.92. His wages plus self-employment earnings total $223,880, which also triggers $214.92 in Additional Medicare Tax. If W-2 wages alone reach $192,300, freelance profit owes only the 2.9% Medicare portion.

Bonuses and pre-tax deductions move your cap date

A bonus pulls the cap date earlier. If the $200,000 earner gets a $20,000 bonus on the March 31 check, year-to-date wages pass $192,300 on the Nov. 15 check instead of Dec. 31. Annual Social Security tax stays at $11,922.60; it is paid off sooner.

IRS Publication 15-B, Employer's Tax Guide to Fringe Benefits, treats traditional 401(k) deferrals as Social Security wages, so they leave the date unchanged. Health premiums paid pre-tax through a cafeteria plan, an employer benefits plan under tax code Section 125, are a different case. At $400 per check, Social Security wages fall to $190,400 for the year, below the $192,300 cap. Every check then pays the full 6.2%, and Social Security tax for the year comes to $11,804.80.

The counter resets on Jan. 1, 2027. A worker who hit the 2026 cap of $184,500 sees full 6.2% withholding return on the first January check, and take-home pay drops by the same amount December added.
