Taxable Wage Base

The taxable wage base is one of the few payroll figures that changes every year and breaks payroll calculations if not updated. The 2026 Social Security wage base of $184,500 reflects the 4.8% inflation adjustment from $176,100. Once an employee's year-to-date wages cross that figure, the 6.2% Social Security portion of FICA stops. Medicare keeps going (no wage base). FUTA stops at $7,000 per employee per year, hitting the cap fast.

2026 Wage Bases at a Glance

Social Security: $184,500. Medicare: no cap (1.45% on all wages, plus 0.9% additional on wages over $200,000). FUTA: $7,000 per employee per year. State unemployment: varies, from $7,000 in some states to $70,000+ in Washington.

How Wage Bases Affect Payroll Math

For high-earners, the Social Security wage base creates a midyear paycheck increase when YTD wages cross $184,500 because the 6.2% withholding stops. Most payroll systems handle this automatically, but it surprises employees who don't expect a take-home increase mid-year.

State Unemployment Wage Base Variation

States set their own SUTA wage bases. Washington and Hawaii have the highest (over $60,000); many states sit at or near the FUTA $7,000 floor. Multi-state employers track multiple wage bases simultaneously. See payroll tax rates for the rate side.

Updating Wage Bases at Year-End

The Social Security wage base is published in October by the SSA. State SUTA bases are published in November-December. Update payroll system configuration in December or early January. Verify with W-2 processing that the new bases applied correctly. SSA reference: ssa.gov/oact/cola/cbb.html.
