What Is Payroll Tax and Who Pays It?
Quick Answer: Payroll tax is a federal and state tax imposed on employers and employees to fund Social Security, Medicare, and unemployment insurance programs.
Payroll tax represents a critical component of the U.S. tax system, funding essential social insurance programs that provide benefits to workers and their families. Unlike income taxes, which are based on total earnings and filing status, payroll taxes are calculated as a flat percentage of wages up to certain limits.
Both employers and employees share the responsibility for payroll taxes, though the burden varies by tax type. As a business owner, understanding these obligations is essential for effective tax planning and compliance.
Who Must Pay Payroll Taxes
- Employers: All businesses with employees must withhold and pay payroll taxes
- Employees: Workers have payroll taxes withheld from their paychecks automatically
- Self-Employed Individuals: Pay self-employment tax, which covers both employer and employee portions
- Business Partners: General partners pay self-employment tax on their share of partnership income
Pro Tip: S Corporation owners who work in their business can minimize payroll tax liability by paying themselves a reasonable salary while taking additional compensation as distributions, which are not subject to payroll taxes.
How Much Are Payroll Taxes in 2025?
Quick Answer: The combined employer-employee payroll tax rate is 15.3% (7.65% each) for Social Security and Medicare, plus unemployment taxes paid by employers.

2025 Payroll Tax Changes
The most significant change for 2025 is the increase in the Social Security wage base from $168,600 in 2024 to $176,100. This means higher-earning employees and their employers will pay Social Security taxes on an additional $7,500 of wages.

How Do You Calculate Payroll Taxes?
Quick Answer: Multiply the applicable tax rate by the employee’s wages, subject to any wage base limits, then add employer-only taxes like FUTA.
Accurate payroll tax calculation requires understanding wage bases, tax rates, and timing requirements. Many businesses benefit from automated payroll systems to ensure compliance and accuracy.
Step-by-Step Calculation Process

- Step 6: Calculate FUTA tax (0.6% on first $7,000 of wages)
- Step 7: Add applicable state unemployment and disability taxes
Payroll Tax Calculation Example
Let’s calculate payroll taxes for an employee earning $8,000 per month ($96,000 annually):
| Tax Component | Rate | Monthly Amount | Annual Amount |
|---|---|---|---|
| Social Security (Employee) | 6.2% | $496 | $5,952 |
| Social Security (Employer) | 6.2% | $496 | $5,952 |
| Medicare (Employee) | 1.45% | $116 | $1,392 |
| Medicare (Employer) | 1.45% | $116 | $1,392 |
| FUTA (First $7,000 only) | 0.6% | $42 (Jan-Feb only) | $42 |
| Total Payroll Taxes | – | $1,266 | $14,730 |
Pro Tip: Use payroll software that automatically tracks wage bases and applies current tax rates to avoid calculation errors that can result in costly penalties.
When Are Payroll Tax Deposits Due?
Quick Answer: Payroll tax deposit schedules depend on your business’s total tax liability, with semi-weekly depositors having shorter deadlines than monthly depositors.
The IRS requires employers to deposit payroll taxes according to specific schedules based on their historical tax liability. Missing these deadlines can result in significant penalties.
Monthly Deposit Schedule
Most small businesses qualify for monthly deposits if their total employment tax liability for the four-quarter lookback period is $50,000 or less.
- Deposit Deadline: 15th of the following month
- Example: January wages must be deposited by February 15th
- Safe Harbor: Deposits made by the next banking day if the 15th falls on a weekend or holiday
Semi-Weekly Deposit Schedule
Larger employers with more than $50,000 in payroll tax liability during the lookback period must make semi-weekly deposits.
- Wednesday Deadline: Deposits for Saturday, Sunday, Monday, and Tuesday paydays
- Friday Deadline: Deposits for Wednesday, Thursday, and Friday paydays
- Next-Day Rule: Deposits of $100,000 or more must be made by the next banking day
Electronic Deposit Requirements
All payroll tax deposits must be made electronically through the Electronic Federal Tax Payment System (EFTPS) or approved third-party providers.
Did You Know? The IRS considers deposits made on time if they’re submitted by 8 PM Eastern Time on the due date through EFTPS, but third-party processors may have earlier cutoff times.
What Are Common Payroll Tax Mistakes to Avoid?
Quick Answer: The most costly payroll tax mistakes include late deposits, incorrect tax calculations, misclassifying workers, and failing to file quarterly returns on time.
Payroll tax errors can be expensive and time-consuming to resolve. Understanding common mistakes helps businesses implement preventive measures and maintain compliance with federal and state requirements.
Top Payroll Tax Compliance Errors
- Late or Missed Deposits: Results in penalties ranging from 2% to 15% of the unpaid tax amount
- Incorrect Worker Classification: Misclassifying employees as independent contractors can trigger back taxes and penalties
- Wage Base Limit Errors: Continuing to withhold Social Security tax after reaching the annual limit
- Form 941 Filing Mistakes: Incorrect reporting on quarterly returns can trigger IRS audits
- State Tax Oversights: Failing to register or pay state unemployment and disability taxes
Penalty Structure for Payroll Tax Violations
The IRS imposes specific penalties for various payroll tax violations, making compliance essential for business financial health.
| Violation Type | Penalty Rate | Maximum Penalty |
|---|---|---|
| Deposit 1-5 days late | 2% of unpaid taxes | No maximum |
| Deposit 6-15 days late | 5% of unpaid taxes | No maximum |
| Deposit 16+ days late | 10% of unpaid taxes | No maximum |
| Paid directly vs. deposit | 10% of unpaid taxes | No maximum |
| Tax not paid within 10 days of IRS notice | 15% of unpaid taxes | No maximum |
Pro Tip: The IRS may waive penalties for first-time offenders or businesses with reasonable cause. Document any circumstances that prevented timely compliance, such as natural disasters or system failures.

Uncle Kam in Action: Manufacturing Company Saves $18,500 Annually
Client Snapshot: A family-owned manufacturing company specializing in custom metal fabrication with 12 employees.
Financial Profile: Annual payroll of $720,000 with the owner drawing a $90,000 salary from their LLC structure.
The Challenge: The business owner was paying over $13,000 annually in self-employment taxes on their $90,000 draw and facing increasing payroll tax costs as the business grew. They were also struggling to attract and retain skilled workers in a competitive market without offering competitive benefits.
The Uncle Kam Solution: Our team implemented a comprehensive payroll tax optimization strategy. First, we converted the LLC to an S Corporation election, allowing the owner to take a reasonable salary of $65,000 with the remaining $25,000 as tax-free distributions. Second, we established a group health plan with HSA contributions, reducing taxable wages by $4,800 per employee annually. Finally, we implemented a SEP-IRA retirement plan with 6% employer contributions.
The Results:
- Tax Savings: The S Corp election saved $3,825 in self-employment taxes, while the HSA and retirement plan strategies reduced overall payroll taxes by $14,720 annually.
- Investment: The comprehensive tax strategy and implementation required a $5,200 investment.
- Return on Investment (ROI): The client achieved a 3.6x return on investment in the first year, with ongoing annual savings of $18,545.
Beyond the tax savings, the enhanced benefits package helped the company attract two experienced welders and reduce turnover by 40%. This is just one example of how our proven tax strategies have helped clients optimize their payroll tax burden while improving their competitive position.

Frequently Asked Questions
What happens if I miss a payroll tax deposit deadline?
Missing payroll tax deposits triggers automatic penalties starting at 2% for deposits 1-5 days late, escalating to 15% for deposits made more than 10 days after an IRS notice. The penalty applies to the entire unpaid tax amount, not just the late portion. Contact the IRS immediately if you miss a deadline to discuss payment arrangements and potentially reduce penalties.
How does the Social Security wage base increase affect my business?
The 2025 Social Security wage base increase to $176,100 means you’ll pay Social Security taxes on an additional $7,500 of wages for high-earning employees. This results in an extra $465 in employer Social Security taxes per affected employee ($7,500 × 6.2%). Employees will also pay an additional $465, making the combined increase $930 per high earner.
Can S Corporation owners avoid payroll taxes entirely?
No, S Corporation owners who work in their business must pay themselves a reasonable salary subject to payroll taxes. However, they can minimize payroll taxes by limiting salary to a reasonable amount for their role and taking additional compensation as distributions, which are not subject to self-employment taxes. The IRS scrutinizes unreasonably low salaries and may reclassify distributions as wages.
What’s the difference between employee and contractor payroll tax obligations?
Employees have payroll taxes withheld automatically and split with their employer (7.65% each for Social Security and Medicare). Independent contractors pay self-employment tax of 15.3% on their net earnings, covering both employer and employee portions. Contractors also make quarterly estimated payments rather than having taxes withheld from each payment.
Are there any payroll tax credits available to offset costs?
Several federal credits can reduce payroll tax liability, including the Work Opportunity Tax Credit (WOTC) for hiring certain targeted groups, the Employee Retention Credit (though this has expired for most businesses), and the Small Business Health Care Tax Credit for businesses providing health insurance. State-level credits may also be available depending on your location and industry.
How long should I keep payroll tax records?
The IRS requires employers to keep payroll tax records for at least four years after the tax becomes due or is paid, whichever is later. However, it’s recommended to keep records for six years due to potential statute of limitations extensions. Essential records include Form 941 quarterly returns, Form 940 annual returns, employee W-4 forms, payroll registers, and tax deposit records.
