Each payroll tax has its own wage base, a maximum annual earnings amount subject to that particular tax. Social Security has one cap. FUTA has another. Every state’s unemployment tax has its own. These caps are different numbers, adjusted annually, and they all reset on January 1. Getting them right matters for every paycheck calculation and year-end reconciliation.

Social Security Wage Base (2026: $184,500)
The Social Security wage base is the maximum annual wages subject to the 6.2% employee and 6.2% employer Social Security tax. For 2026, the Social Security Administration set this at $184,500, up from $176,100 in 2025 and $168,600 in 2024. Any wages earned above that amount aren’t subject to Social Security tax. The base increases annually based on a formula tied to national average wage growth, which means a fresh recalculation every January. If you don’t stop withholding at the cap, you over-collect. If you stop too early, the employee may end up responsible for the shortfall.
FUTA Wage Base ($7,000)
The federal unemployment tax (FUTA) applies only to the first $7,000 in wages per employee per calendar year. FUTA is an employer-only tax at 0.6% standard, potentially higher if your state has an outstanding loan. Once an employee earns $7,000, no additional FUTA tax is due for the rest of the year. This wage base has been $7,000 since 1983 and has never been adjusted for inflation.
State Unemployment (SUTA) Wage Bases: Highly Variable
SUTA wage bases vary a lot by state and are adjusted annually. For 2026, California sits at $7,000 (unchanged), Washington jumped to $78,200, Colorado is $30,600, New York rose sharply to $17,600, Massachusetts holds at $15,000, and Illinois moved to $14,250. Multi-state employers can’t use a single number across the board. You track each state’s base, apply it per employee, and update every January. One miscalculation on a higher-base state compounds across every affected employee, year after year.
Medicare Tax: No Wage Base Cap
Unlike Social Security, Medicare has no annual wage base cap. The 1.45% employee and 1.45% employer tax applies to all wages, all year, with no ceiling. High earners pay an extra 0.9% on wages above $200,000 (single) or $250,000 (married filing jointly). That additional 0.9% has no employer match. It’s withheld entirely from the employee and requires separate tracking once those thresholds are crossed.
Bottom Line
Wage bases require an annual review and system update. A single miscalculation multiplies across every paycheck and every employee above that threshold. For highly compensated employees and multi-state operations, accuracy here isn’t optional. It’s the foundation of year-end reconciliation and audit defense.
Frequently Asked Questions
Each tax was designed to fund different benefits. Social Security is a national program with indexed wage bases adjusting for national wage growth. FUTA is federal unemployment with a static $7,000 base unchanged since 1983. SUTA is state unemployment with state-determined bases. Medicare has no cap because it’s designed to be a tax on all wages. Different legislative histories created this complexity.
SUTA is calculated per employee per state annually. If your wage base is wrong, you’ll either under-pay SUTA, creating a tax liability when audited, or over-pay, losing money. A single percentage point error on a $30,600 wage base for 100 employees costs several thousand dollars in errors per year. Over multiple years, this compounds significantly.
Yes. In addition to the standard 1.45% Medicare tax, high-income earners over $200,000 single or $250,000 married owe an additional 0.9% Medicare tax. This is withheld entirely from the employee with no employer match. Employers must track cumulative wages and withhold the additional Medicare tax once thresholds are crossed, which requires separate tracking from standard Medicare withholding.
The Social Security Administration set the 2026 taxable wage base at $184,500, up from $176,100 in 2025, an increase of roughly 4.8%. Wages above that amount are not subject to the 6.2% Social Security tax for either the employee or the employer.
