- Payroll Taxes include Social Security, Medicare, and unemployment taxes, and are shared between the employer and the employee, with employers covering additional taxes.
- Income Taxes are withheld from employees' paychecks and are the employee's responsibility to pay, with employers acting as intermediaries.
- The primary difference is that payroll taxes fund specific programs, such as Social Security, while income taxes fund government operations.
- Employers are responsible for calculating, withholding, and remitting both payroll and income taxes.
- Non-compliance with payroll or income tax rules can result in penalties, interest, and potential audits, making accuracy and timeliness crucial.
Running payroll shouldn’t feel like navigating a maze, but for many employers, it often does.
One of the most common points of confusion? Understanding the difference between payroll tax and income tax. At first glance, they can seem similar as they both involve deductions from employee paychecks and regular filings. However, mixing them up can be costly.
Simple misunderstandings or missed deadlines may lead to penalties, compliance issues, and unnecessary stress. As an employer, staying compliant means knowing exactly which taxes you’re responsible for, which ones your employees pay, and how to manage both correctly. Once you understand how these two tax types work and how they differ, managing payroll becomes much simpler.
In this article, we’ll clearly explain the differences between payroll tax and income tax, what each one covers, and what you need to do to stay on the right side of the law.
Let’s break down these two terms first.
What is Payroll Tax?

Payroll taxes are the taxes tied directly to employment. As an employer, you're responsible not only for withholding certain amounts from employee paychecks but also for paying your own share of these taxes.
Here’s a breakdown of what payroll tax typically includes:
1. Social Security and Medicare (FICA)
- These are federal taxes under the Federal Insurance Contributions Act (FICA).
- Both the employer and employee contribute:
- Social Security: 6.2% from the employee and 6.2% from the employer
- Medicare: 1.45% from each (plus an extra 0.9% for high earners, employee-paid only)
2. Federal Unemployment Tax (FUTA)
- Employers pay this tax to fund unemployment benefits.
- Employees do not contribute to FUTA.
- The standard FUTA rate is 6.0% on the first $7,000 of each employee’s wages, though most employers receive a credit that lowers it to 0.6%.
3. State Unemployment Tax (SUTA)
- Like FUTA, this is employer-paid (in most states) and helps fund state-level unemployment benefits.
- Rates and wage bases vary by state, and some states require minimal employee contributions.
4. Other Local Payroll Taxes
- Some cities and states (like New York or Pennsylvania) impose additional payroll taxes, such as transit or training taxes.
- These vary widely depending on location.
Key Takeaway: Payroll taxes are employment-related taxes that employers must withhold and/or pay directly. They fund programs like Social Security, Medicare, and unemployment insurance, and failing to manage them properly can trigger penalties and interest.
What Is Income Tax?

Income tax is the tax withheld from an employee’s paycheck based on how much they earn. Unlike payroll taxes, income taxes are entirely the employee’s responsibility to pay, but as an employer, it’s your job to withhold and remit them accurately.
Here’s how it works:
1. Federal Income Tax
- Withholding is based on information provided by the employee on their W-4 form.
- The IRS provides employers with tools (like tax tables or software) to calculate the right amount to withhold.
- Withheld amounts are sent to the IRS on a regular schedule and reported at year-end via Form W-2.
2. State Income Tax
- Most states also require income tax withholding.
- Rates and rules vary by state; some states have flat rates, others use tax brackets.
- A few states (like Texas and Florida) don’t have state income tax at all.
3. Local Income Tax
- In certain jurisdictions (e.g., New York City, Philadelphia), local governments impose additional income taxes.
- These may apply to residents, commuters, or people who work within city limits.
Key Takeaway: Income tax is the employee’s tax obligation on earnings, but the employer is responsible for correctly calculating, withholding, and remitting it. Getting it wrong could lead to underpayments, frustrated employees, or tax notices from the IRS or state agencies.
That brings us to the differences between these taxes. Let's learn these differences below.
Key Differences Between Payroll Tax and Income Tax
While both payroll and income taxes are tied to employee wages and deducted from paychecks, they serve different purposes, follow different rules, and involve different responsibilities for employers.
Here’s a clear breakdown of the main differences:
In short:
- Payroll tax is about supporting specific government programs through shared contributions.
- Income tax is about taxing the employee’s total earnings, and the employer acts as the middleman.
Understanding these differences helps ensure correct withholding, reporting, and filing, keeping your business compliant and your employees paid correctly.
Calculations & Examples
To help illustrate the differences clearly, here are two practical, step-by-step examples employers encounter each pay period.
Payroll Tax Example (FICA + FUTA + SUTA)
Scenario: An employee earns $5,000 in gross wages for a biweekly pay period.
1. FICA (Social Security + Medicare)
2. FUTA (Federal Unemployment Tax)
- Rate: 0.6% (after credit)
- Wage Limit: First $7,000/year
- Employer Pays: $5,000 × 0.6% = $30.00
3. SUTA (State Unemployment Tax)
- Example Rate: 5%
- Wage Limit: First $7,000/year
- Employer Pays: Approx. $19.23 for this pay period
2. Income Tax Example (Using Wage-Bracket vs Percentage Method)
Scenario: Employee earns $3,000 monthly, files as Single with no adjustments on W‑4.
Option A: Wage-Bracket Method
- Based on IRS Publication 15-T tables
- Monthly income of $3,000 → Approx. $300 withheld
Option B: Percentage Method
- Used for higher incomes or automated systems
- IRS base: $250 + 12% of the amount over $2,800
- Excess: $200 → 12% of $200 = $24
- Total withheld: $250 + $24 = $274
Along with the right calculations, it's equally important for employers to understand their ongoing responsibilities to stay compliant.
Employer Responsibilities for Payroll & Income Tax Compliance
As an employer, you're the one who calculates, withholds, and remits both payroll taxes (e.g., FICA, FUTA/SUTA) and income taxes (federal, state, local). That means:
1. Registration & Classification
- Obtain an EIN from the IRS to report taxes and file forms.
- Properly classify workers as employees or independent contractors. Misclassification can lead to steep penalties.
2. Correct Withholding & Payment
- Payroll Tax:
- Withhold employee share of Social Security and Medicare (FICA), match with employer share, and remit FUTA/SUTA as required.
- Make deposits via EFTPS on a semi-weekly, monthly, or quarterly schedule per IRS guidelines.
- Income Tax:
- Use employee W‑4 forms and IRS/state tables to withhold correct federal/state/local income taxes.
- Remit these taxes on the same deposit schedule and ensure timely payment.
3. Filing Requirements & Reporting
- Quarterly/annual forms:
- IRS Form 941 for federal payroll taxes, Form 940 for FUTA, and state-specific equivalents.
- Year-end reporting:
- Issue Form W‑2 to employees (and file with SSA); file 1099‑NEC for contractors.
- Maintain accurate payroll records for deductions, withholdings, and contributions, which are critical during audits.
4. Stay Updated & Audit-Proof
- Keep W‑4s, wage rates, and withholding tables current. Employees should update their W‑4s when life changes occur.
- Monitor federal, state, and local tax rate changes, as mismatched rates can trigger fines.
- Conduct internal payroll audits periodically to catch errors before authorities do.
Understanding your responsibilities is one thing, and consistently executing them is another. To make compliance easier, here are a few proven best practices to follow.
Best Practices for Payroll & Income Tax Compliance

To stay compliant and avoid costly mistakes, adopt the following trusted strategies:
- Use Reliable Payroll & HR Software: Automate your processes to reduce manual errors and ensure timely filings. Quality tools keep tax tables and regulations up-to-date, significantly lowering compliance risks.
- Run Regular Internal Audits: Conduct periodic audits of your payroll system, including worker classification, withholding accuracy, and deposit timing, to catch issues before they lead to penalties.
- Maintain a Robust Compliance Checklist: Track key tasks: EIN registration, new-hire reporting, worker classification, correct tax withholding, deposits, quarterly filings, and secure record-keeping.
- Stay Updated on Law Changes: Monitor updates to wage bases (e.g., Social Security cap), minimum wage rates, and payroll-related thresholds each year.
- Classify Workers Correctly: Misclassification is a leading source of non-compliance. Follow IRS and state guidelines closely, and re-evaluate classifications when roles change.
- Automate Time Tracking & Integration: Sync timekeeping with payroll to reduce discrepancies in hours, overtime, and PTO, which materially impact withholding and tax reporting.
- Schedule Tax Deposit & Filing Reminders: Use software or calendar alerts for due dates on Forms 941/940, income tax deposits, W-2 issuance, and state filings. Late payments can incur penalties of 2–15%.
- Secure & Organize Records: Keep detailed payroll logs, W-4s, W-2s, I-9s, timecards, and deposit confirmations for at least three to four years, crucial for audits and compliance documentation.
