Understanding Payroll Taxes
What Are Payroll Taxes?

Payroll Tax = Employee Wages × Payroll Tax Rate
These taxes fund Social Security and Medicare programs.

Who Pays Payroll Taxes?

Payroll Tax Tips
Test Your Knowledge
Question 1: Basic Calculation
If an employee earns $60,000 annually and the combined payroll tax rate is 7.65%, what is the employee's share of payroll tax?
The correct answer is C) $4,590.00. Using the formula: Payroll Tax = Employee Wages × Payroll Tax Rate = $60,000 × 0.0765 = $4,590.00
The formula for payroll tax is: Payroll Tax = Employee Wages × Payroll Tax Rate
Question 2: Social Security Wage Base
What is the 2023 wage base limit for Social Security taxes?
The correct answer is B) $160,200. The Social Security tax applies only to the first $160,200 of wages in 2023. Any wages earned above this threshold are not subject to Social Security tax.
The Social Security wage base limit changes annually based on average wage increases, but Medicare tax applies to all wages with no limit.
Question 3: Additional Medicare Tax
At what income level does the additional Medicare tax of 0.9% apply for single filers?
The correct answer is C) $200,000. The additional Medicare tax of 0.9% applies to wages over $200,000 for single filers. For married filing jointly, it applies to wages over $250,000.
High earners should factor in the additional 0.9% Medicare tax when planning compensation packages or making financial decisions.
Question 4: Employer vs Employee Share
Who pays the employer portion of payroll taxes?
The correct answer is B) The employer pays the employer share. For Social Security and Medicare taxes, both the employee and employer pay equal shares. The employer withholds the employee portion and pays the employer portion separately.
Employers must remember that their total payroll tax obligation is double what employees see on their pay stubs, as they must match employee contributions.
Question 5: Self-Employment Calculation
If a self-employed individual earns $80,000, what is their total payroll tax obligation (rounded to nearest dollar)?
The correct answer is B) $12,240. Self-employed individuals pay both the employee and employer portions (15.3% total). Calculation: $80,000 × 0.153 = $12,240. However, they can deduct half of this amount as a business expense.
Self-employed individuals often underestimate their tax obligations because they must pay both portions of payroll taxes, unlike employees who only pay the employee portion.
Q&A
Q: I noticed payroll taxes being deducted from my paycheck. What are they for and how much should I expect to pay?
A: Payroll taxes fund Social Security and Medicare programs:
Standard Rates (2023):
- Social Security: 6.2% of your wages (up to $160,200)
- Medicare: 1.45% of your wages (no limit)
- Additional Medicare: 0.9% if you earn over $200,000 (single) or $250,000 (joint)
Calculation Example:
- Annual wages: $50,000
- Social Security: $50,000 × 0.062 = $3,100
- Medicare: $50,000 × 0.0145 = $725
- Total employee payroll tax: $3,825
Remember, your employer pays matching amounts, so the total contribution to Social Security/Medicare is 15.3% of your wages.
Q: As an employer, what are my responsibilities regarding payroll taxes?
A: Employers have significant responsibilities for payroll taxes:
Withholding Requirements:
- Withhold employee portions of Social Security (6.2%) and Medicare (1.45%) from wages
- Withhold Additional Medicare Tax (0.9%) if employee earns over $200,000
- Report and deposit taxes regularly (usually semi-weekly or monthly)
Employer Contributions:
- Match employee Social Security and Medicare contributions dollar-for-dollar
- Pay federal unemployment tax (FUTA) on first $7,000 of each employee's wages
- File quarterly reports (Form 941) and annual summaries (Form W-2)
Important: Penalties for late deposits can be severe, ranging from 2% to 15% of unpaid taxes depending on how late the payment is.
Q: I just started my own business. How do payroll taxes work for self-employed individuals?
A: Self-employed individuals pay "self-employment tax" which covers both the employee and employer portions of Social Security and Medicare:
Self-Employment Tax Rates (2023):
- Social Security: 12.4% on first $160,200 of net earnings
- Medicare: 2.9% on all net earnings
- Additional Medicare: Extra 0.9% on net earnings over $400,000 (single) or $500,000 (joint)
- Total: Up to 15.3% on most earnings
Special Benefits:
- You can deduct half of your self-employment tax as a business expense
- This reduces your adjusted gross income
- You may need to make estimated tax payments quarterly
Example: If you earn $80,000 in net self-employment income, your self-employment tax would be $80,000 × 0.153 = $12,240. However, you can deduct $6,120 as a business expense.
