What Are Payroll Taxes?
Payroll taxes are taxes that employers are required to withhold from employees’ wages and also pay themselves. They fund essential government programs like Social Security, Medicare, and unemployment insurance.
🔑 Key Components of Payroll Taxes:
1. Employee Withholding:
- Federal Income Tax
- Social Security Tax (6.2% on wages up to $168,600 in 2025)
- Medicare Tax (1.45% on all wages; additional 0.9% over $200,000)
- State Income Tax (varies by state)
2. Employer Contributions:
- Social Security Tax (6.2%)
- Medicare Tax (1.45%)
- Federal Unemployment Tax (FUTA): 6.0% on the first $7,000 in wages (may be reduced by credits)
- State Unemployment Tax (SUTA): Varies by state
How Payroll Taxes Are Calculated
Payroll tax calculation requires a combination of employee information, current IRS tax tables, and wage data. Here’s a simplified step-by-step guide:
Step 1: Determine Gross Pay
This includes hourly wages, salaries, bonuses, and other compensation.
Step 2: Calculate Withholdings
Use IRS Form W-4 and state equivalents to determine how much to withhold from employee pay.
Step 3: Calculate Employer Contributions
Match Social Security and Medicare, and calculate unemployment taxes based on state/federal rules.
💡 Tip: Use IRS Publication 15 (Circular E) or a payroll software tool to automate tax calculations and ensure accuracy.
Reporting and Depositing Payroll Taxes
Timely reporting and depositing are essential to stay compliant and avoid penalties.
Federal Requirements:
- File Form 941 (quarterly) or Form 944 (annually for eligible small businesses)
- Deposit withheld and employer payroll taxes either semiweekly or monthly, depending on your deposit schedule
- Use the Electronic Federal Tax Payment System (EFTPS) for deposits
State Requirements:
- Filing and deposit rules vary by state
- Register with your state’s tax or revenue department
📈 In 2023, the IRS issued over $5 billion in civil penalties related to payroll tax errors—underscoring the need for accurate and timely compliance.
