The Social Security Administration announced a $184,500 wage base for 2026 — an $8,400 increase from 2025's $176,100. Maximum SS tax per employee rises to $11,439 on both the employer and employee side.
- Social Security wage base is $184,500 for 2026 — up $8,400 from 2025's $176,100.
- Maximum Social Security tax per employee: $11,439 (each side — employer and employee).
- Additional employer SS cost: $520.80 per high-earning employee ($8,400 × 6.2%).
- Medicare has no wage base cap — 1.45% applies to all wages on both sides, unchanged.
- Minnesota PFML uses the SS wage base rounded to nearest thousand — confirming its 2026 wage base at $185,000.
What Changed and Why It Matters
Each year, the Social Security Administration (SSA) announces the contribution and benefit base — the ceiling of earnings on which employers and employees owe the 6.2% Old-Age, Survivors, and Disability Insurance (OASDI) tax. For 2026, that ceiling rises to $184,500, up from $176,100 in 2025. That represents an increase of $8,400 — the largest dollar increase since 2023 — and it directly affects payroll budgets for any employee whose total annual wages approach or exceed the cap.
The adjustment is driven by SSA's annual indexing formula, which ties the wage base to changes in the national average wage index (NAWI). Because NAWI increased during the measurement period, the wage base rose proportionally. The OASDI rate itself — 6.2% for both employee and employer — is unchanged and has remained constant since 2019.
| Component | Employee Rate | Employer Rate | 2026 Wage Base | Max Employee Tax |
|---|---|---|---|---|
| Social Security (OASDI) | 6.2% | 6.2% | $184,500 | $11,439.00 |
| Medicare (HI) | 1.45% | 1.45% | No limit | No cap |
| Additional Medicare Tax | 0.9% | No match | $200,000 threshold (single) | Employee only |
| Combined FICA rate (employee) | 7.65% | 7.65% | Up to $184,500 OASDI cap |
Year-Over-Year Change: 2025 to 2026
| Tax Year | Wage Base | Annual Change | Max Employee OASDI Tax |
|---|---|---|---|
| 2022 | $147,000 | ↑ +$4,200 | $9,114.00 |
| 2023 | $160,200 | ↑ +$13,200 | $9,932.40 |
| 2024 | $168,600 | ↑ +$8,400 | $10,453.20 |
| 2025 | $176,100 | ↑ +$7,500 | $10,918.20 |
| 2026 | $184,500 | ↑ +$8,400 | $11,439.00 |
Budget Impact per High-Earning Employee
The wage base increase raises the maximum OASDI contribution for both the employee and the employer. For any employee whose wages reach or exceed $184,500 in 2026, the additional cost compared to 2025 is $520.80 per year — identical for both the employee and employer sides, since the rate is symmetric. The following examples illustrate the practical payroll impact:
| Annual Wages | Employee OASDI (6.2%) | Employer Match (6.2%) | Combined Total |
|---|---|---|---|
| $80,000 | $4,960.00 | $4,960.00 | $9,920.00 |
| $120,000 | $7,440.00 | $7,440.00 | $14,880.00 |
| $150,000 | $9,300.00 | $9,300.00 | $18,600.00 |
| $184,500 or more | $11,439.00 (cap) | $11,439.00 (cap) | $22,878.00 |
Medicare: No Change for 2026
Unlike OASDI, Medicare's Hospital Insurance (HI) tax has no wage ceiling. Both the employee and employer continue to pay 1.45% on all wages, regardless of the total amount earned. High-earning employees also remain subject to the Additional Medicare Tax of 0.9% on wages exceeding $200,000 in a calendar year (the threshold is $250,000 for married couples filing jointly, and $125,000 for married filing separately). This additional 0.9% is withheld only from the employee's wages — employers do not match it.
Self-employed individuals pay the full 12.4% OASDI tax on net self-employment income up to $184,500, plus 2.9% Medicare on all income — for a combined 15.3% self-employment tax before any deductions. The deductible employer-equivalent portion (half of the self-employment tax) continues to offset a portion of self-employment income for federal income tax purposes.
Year-End Withholding Considerations
One payroll dynamic that directly affects employees and payroll system logic is the wage cap stop: once an employee's year-to-date Social Security wages reach $184,500, OASDI withholding ceases for the remainder of the calendar year. Employees often notice a modest increase in take-home pay at that point. The OASDI clock resets on January 1 of the following year.
