Payroll Tax Calculator 2026 - FICA Social Security and Medicare for Employers and Employees

FICA taxes - the Federal Insurance Contributions Act taxes that fund Social Security and Medicare - are split equally between employee and employer. Total Payroll Tax = Employee Share + Employer Share (FICA). Combined rate: 15.3 percent (7.65 percent each) on wages up to the Social Security wage base.

How FICA Taxes Work

Social Security Tax: Employee pays 6.2%, Employer pays 6.2% (combined 12.4%). Applies to wages up to the Social Security wage base (projected $183,900 for 2026).

Medicare Tax: Employee pays 1.45%, Employer pays 1.45% (combined 2.9%). No wage base cap. Additional Medicare Tax: Employee only, 0.9% on wages above $200,000.

The Formula Explained

Employee FICA (below SS wage base, no AMT): Gross Wages x 0.0765. Employer FICA: Gross Wages x 0.0765. Total FICA: Gross Wages x 0.153.

Worked example ($75,000 annual salary, biweekly): Biweekly gross: $2,884.62. Employee SS: $178.85. Employee Medicare: $41.83. Total employee FICA: $220.68/period. Employer FICA: same $220.68. Total FICA deposit: $441.36 per biweekly paycheck.

3 Real-World Examples

Example 1: Small Business Owner Running Weekly Payroll for Two Employees

Employee 1 ($950/week): FICA withholding $72.68/week. Employee 2 ($420/week): FICA withholding $32.13/week. Total weekly FICA deposit: ($72.68 + $32.13) employee + ($72.68 + $32.13) employer = $209.62/week.

Example 2: High-Earning Employee Hitting the Social Security Wage Base

Michael earns $220,000/year ($9,166.67 semi-monthly). Hits SS wage base partway through 21st pay period (mid-October). Annual total: SS tax $11,402 (capped). Medicare: $3,190. Additional Medicare Tax: $180. Total employee FICA: $14,772.

Example 3: Employer Calculating Total Labor Cost

$65,000 annual salary. Employer SS: $4,030. Employer Medicare: $942.50. Total employer FICA: $4,972.50. True total employment cost: $65,000 + $4,972.50 = $69,972.50 before benefits, workers comp, and unemployment insurance.

Frequently asked questions

What are the FICA tax rates for 2026?

The FICA tax rates for 2026 are: Social Security tax at 6.2 percent each for employee and employer (12.4 percent combined) on wages up to the Social Security wage base projected at approximately $183,900. Medicare tax at 1.45 percent each (2.9 percent combined) on all wages with no cap. Employees with wages exceeding $200,000 also pay the Additional Medicare Tax of 0.9 percent - this is employee-only and employers do not match it.

What is the Social Security wage base for 2026?

The Social Security wage base is adjusted each year based on average national wage growth. For 2025 it is $176,100. For 2026 it is projected to increase to approximately $183,900 based on current wage growth trends, though the official figure is announced by the Social Security Administration each October. Once an employee's annual wages reach this limit, no further Social Security tax is withheld for the rest of that calendar year.

Do employers pay more payroll tax than employees?

For most wages, employers and employees each pay exactly the same FICA amount - 6.2 percent Social Security and 1.45 percent Medicare for a total of 7.65 percent each. The one exception is the Additional Medicare Tax of 0.9 percent which applies to employees but not employers on wages above $200,000. For wages above the Social Security wage base, both employee and employer pay only the 1.45 percent Medicare rate.

Are independent contractors subject to FICA payroll tax?

Independent contractors are not subject to FICA withholding by the business that pays them. However, they are subject to self-employment tax, which is the self-employed person's version of FICA at 15.3 percent of net earnings on the first $183,900 projected for 2026. This is equivalent to paying both the employee and employer shares of FICA. Self-employed workers can deduct half of their SE tax as an above-the-line deduction.

How often do employers need to deposit payroll taxes?

The IRS payroll tax deposit frequency depends on the employer's total payroll tax liability during the lookback period. New employers start as monthly depositors with taxes due by the 15th of the following month. If the lookback period liability exceeded $50,000, the employer is a semi-weekly depositor. The failure-to-deposit penalty starts at 2 percent for deposits 1 to 5 days late and can reach 15 percent.
