Employer Total Cost: $5,000.00 + $390.03 = $5,390.03
Note: FUTA is calculated on first $7,000 annual wages. At $5,000 biweekly, FUTA cap may be reached mid-year.
💰 High Earner — $15,000 Monthly with Additional Medicare
A highly compensated employee earns $15,000 monthly in 2025 with $195,000 YTD wages. Combined with this period, total exceeds the $200,000 Additional Medicare threshold.
Employer Taxes: SS $49.60 + Medicare $11.60 + FUTA $48.00 (annualized) + SUTA $21.60 (annualized) — per period: varies
For this employee earning $800/week, FUTA applies to the first $7,000 (taxed at $48 per week until cap is reached in ~9 weeks).
Understanding Payroll Taxes
Payroll taxes are taxes imposed on employers and employees, typically used to fund social insurance programs including Social Security, Medicare, and unemployment compensation. The key distinction is that some taxes are paid solely by the employee (Additional Medicare), some by both parties (Social Security and Medicare), and some solely by the employer (FUTA and SUTA).

Employee Take-Home = Gross Pay − Employee Taxes
Employee payroll taxes reduce gross pay: SS (6.2% of gross up to wage base) + Medicare (1.45%) + Additional Medicare (0.9% on wages over $200K)
Employer Total Cost = Gross Pay + Employer Taxes
Employer pays matching SS + Medicare + FUTA (6% on first $7K) + SUTA (state rate on state wage base)
How to Calculate Payroll Taxes Step by Step
1
Calculate annual gross: Multiply gross pay per period by the number of pay periods in a year (52 weekly, 26 biweekly, 24 semimonthly, 12 monthly)
2
Employee Social Security: 6.2% × gross pay per period, but only until cumulative wages reach the annual wage base ($176,100 for 2025)
3
Employee Medicare: 1.45% × gross pay per period (no wage cap — applies to all wages)
4
Additional Medicare: 0.9% × wages exceeding $200,000 threshold (combine YTD + this period's wages to determine if threshold is exceeded)
5
Employer Social Security and Medicare: Employer matches employee SS (6.2%) and Medicare (1.45%) on the same wage base. Employer does NOT pay Additional Medicare.
6
FUTA: 6.0% × wages up to $7,000 annually. Calculate per period by determining what portion of the $7,000 cap is consumed.
7
SUTA: State rate × wages up to state wage base. Similar to FUTA, calculated based on remaining state wage base capacity.
Tips for Managing Payroll Taxes
📅 Track Wage Bases
Once an employee's YTD wages exceed the Social Security wage base ($176,100) or FUTA cap ($7,000), those taxes stop being withheld for the remainder of the year.
💰 Budget for Employer Costs
Employers should budget an additional 7.65% to 10%+ on top of gross wages for payroll taxes (SS + Medicare + FUTA + SUTA).
🏛️ Know Your SUTA Rate
State unemployment tax rates vary dramatically — from under 1% to over 10% depending on your state and experience rating. Check your state's workforce agency.
📊 Monitor YTD Wages
For high earners, track YTD wages carefully. Once total wages exceed $200,000, the 0.9% Additional Medicare surtax applies to all further wages for the rest of the year.

Payroll taxes are taxes imposed on employers and employees that fund social insurance programs. In the United States, the main payroll taxes include Social Security (OASDI), Medicare (HI), Additional Medicare, FUTA (Federal Unemployment Tax Act), and SUTA (State Unemployment Tax Act). These taxes are typically calculated as a percentage of an employee's wages, often subject to annual wage base limits.
Understanding payroll taxes is essential for both employers and employees. For employees, payroll taxes directly reduce take-home pay and must be accurately withheld by employers. For employers, payroll taxes represent a significant additional cost above gross wages — typically adding 7.65% to 10% or more on top of each employee's salary.
Understanding Your Results
The Payroll Tax Calculator provides a complete breakdown of both employee-side and employer-side payroll taxes. Employee taxes are deducted from gross wages and include Social Security (6.2%), Medicare (1.45%), and potentially Additional Medicare (0.9% for high earners). Employer taxes are paid on top of gross wages and include matching Social Security (6.2%), matching Medicare (1.45%), FUTA (6.0% on first $7,000), and SUTA (a state-specific rate on a state-specific wage base). The calculator also shows the employee's take-home pay, the employer's total cost, the combined tax burden, and the effective tax rate.
Why Payroll Tax Calculations Matter
Accurate payroll tax calculation is critical for businesses of all sizes. Here's why it matters:
⚖️ Legal Compliance
Employers are legally required to withhold and remit payroll taxes. Failure to do so can result in significant penalties, interest charges, and even criminal liability.
💰 Budgeting Accuracy
Knowing the true cost of an employee (gross wages plus employer taxes) is essential for accurate budgeting, pricing, and profitability analysis.
📋 Paycheck Accuracy
Employees rely on accurate payroll tax withholding for their financial planning. Errors can lead to unexpected tax bills or overpayment of taxes throughout the year.
📈 Year-End Planning
Understanding how wage bases affect payroll taxes helps with year-end planning — for example, when an employee's wages exceed the Social Security cap, their paycheck increases for the remainder of the year.
Frequently Asked Questions
What is the difference between payroll taxes and income taxes?
Payroll taxes (Social Security, Medicare, FUTA, SUTA) are specific percentages of wages used to fund social insurance programs. They are flat rates with wage base caps. Income taxes are based on taxable income and use progressive tax brackets. Payroll taxes are separate from income taxes — both are typically withheld from paychecks but calculated differently and go to different government programs.
What is the Social Security wage base for 2025 and 2026?
The Social Security wage base for 2025 is $176,100. For 2026, it is estimated to be $178,200. Wages above these amounts are not subject to Social Security tax. The Medicare wage base has no cap — all wages are subject to the 1.45% Medicare tax.
Who pays Additional Medicare tax?
The Additional Medicare Tax of 0.9% is paid by employees only — employers do not match this tax. It applies to wages that exceed $200,000 for single filers ($250,000 for married filing jointly, $125,000 for married filing separately). Once an employee's wages exceed the threshold, the 0.9% tax applies to all wages above that amount for the remainder of the calendar year.
What is FUTA and how is it calculated?
FUTA (Federal Unemployment Tax Act) is a tax paid by employers only — never by employees. The rate is 6.0% on the first $7,000 of each employee's wages per year. Most employers receive a credit of up to 5.4% for paying state unemployment taxes, effectively reducing the FUTA rate to 0.6% for those who qualify.
What is SUTA and how does it vary by state?
SUTA (State Unemployment Tax Act) is a state-level tax paid by employers to fund unemployment benefits. SUTA rates vary significantly by state — from under 1% to over 10% — and are determined by your state's unemployment fund and your company's experience rating (how many former employees have filed claims). The wage base also varies by state, ranging from $7,000 to over $50,000.
Do employers really pay more than what I see on my paycheck?
Yes. Employers pay additional payroll taxes on top of your gross wages. For every dollar of gross wages you earn, your employer typically pays an additional 7.65% to 10%+ in employer-side payroll taxes (matching Social Security, matching Medicare, FUTA, and SUTA). This is why the "employer total cost" is always higher than your gross salary.
