Understanding Payroll Taxes
Payroll taxes are deductions from employee wages to fund federal and state programs, including Social Security, Medicare, and income taxes. Employers withhold these taxes and may also contribute matching amounts for Social Security and Medicare.
Employer vs. Employee Responsibilities
Employee: Pays Social Security (6.2%), Medicare (1.45%), and income taxes based on filing status and wages.
Employer: Matches Social Security and Medicare contributions and withholds income taxes per IRS guidelines.
How to Calculate Payroll Taxes
Payroll taxes are calculated based on gross wages, adjusted for pay frequency, filing status, and dependents. The calculator uses 2025 federal tax rates and a user-input state tax rate for estimates.
Net Pay = Gross Wages – Total Payroll Taxes
Social Security Tax = Wages × 6.2% (up to $168,600 in 2025)
Medicare Tax = Wages × 1.45% (+ 0.9% for wages > $200,000 single)
Federal Income Tax = Based on IRS tax brackets and allowances
State Income Tax = Wages × State Tax Rate
• Wages = Gross wages for the pay period
• Social Security Cap = $168,600 (2025)
• Medicare Additional Tax = 0.9% for high earners
• Federal Income Tax = Adjusted for filing status and dependents
• State Tax Rate = User-entered percentage
Step-by-Step Example
For a single employee with $2,000 monthly wages, 1 dependent, 5% state tax:
Social Security: $2,000 × 6.2% = $124.
Medicare: $2,000 × 1.45% = $29.
Federal Income Tax: Approx. $150 (based on simplified 2025 brackets for single filer).
State Income Tax: $2,000 × 5% = $100.
Total Taxes: $124 + $29 + $150 + $100 = $403.
Net Pay: $2,000 – $403 = $1,597.
Advanced Considerations
Federal income tax varies by filing status and deductions. Dependents reduce taxable income ($4,300 per dependent in 2025). State taxes vary by jurisdiction; some states have no income tax.
