What Are Payroll Taxes?
Payroll taxes are mandatory deductions from an employee’s wages, covering federal and state taxes, Social Security, Medicare, and other withholdings. Employers must deduct these taxes from employee wages and remit them to government agencies.
Types of Payroll Taxes:
- Federal Income Tax – Withheld based on IRS tax brackets.
- State Income Tax – Varies by state; some states have no income tax.
- Social Security Tax (6.2%) – Shared between employer and employee.
- Medicare Tax (1.45%) – Also split between employer and employee.
- Additional Medicare Tax (0.9%) – Applies to high earners.
- FUTA (Federal Unemployment Tax Act) & SUTA (State Unemployment Tax Act) – Paid by employers.
Step-by-Step Guide How to Calculate Payroll Taxes Like a Pro?
Step 1: Determine Gross Pay
Gross pay is the total earnings before any deductions. This includes hourly wages, salaries, overtime, bonuses, and commissions.
Example:
If an employee earns $5,000 per month, their gross pay is $5,000.
Step 2: Calculate Federal Income Tax Withholding
Federal income tax depends on the employee’s Form W-4 details, filing status, and IRS tax brackets. Use the IRS withholding tables or an online tool like the IRS Tax Withholding Estimator to get accurate deductions.
Step 3: Deduct Social Security and Medicare Taxes
- Social Security Tax = Gross Pay × 6.2%
- Medicare Tax = Gross Pay × 1.45%
Example Calculation:
If an employee earns $5,000 per month, their deductions will be:
- Social Security Tax: $5,000 × 6.2% = $310
- Medicare Tax: $5,000 × 1.45% = $72.50
Step 4: Withhold State Income Tax (If Applicable)
State income tax rates vary. Some states like Texas, Florida, and Nevada have no state income tax, while others have progressive or flat tax rates.
Example: In California, an employee earning $5,000 might have 6% withheld, or $300.
Step 5: Deduct Other Benefits & Contributions
Employers may deduct:
✔️ 401(k) or Retirement Contributions
✔️ Health Insurance Premiums
✔️ HSA (Health Savings Account) Contributions
✔️ Union Dues
Step 6: Calculate Net Pay (Take-Home Salary)
Net Pay = Gross Pay – Total Deductions
Example Calculation:
- Gross Pay = $5,000
- Federal Income Tax = $500
- Social Security = $310
- Medicare = $72.50
- State Tax (6%) = $300
- Health Insurance = $100
Total Deductions = $1,282.50
Net Pay = $3,717.50
