How do payroll taxes differ from income taxes?

Understanding Payroll Taxes vs. Income Taxes in Illinois

In Illinois, payroll taxes and income taxes serve different operational purposes for businesses and employees. Knowing these differences helps ensure accurate payroll management and compliance.

What Are Payroll Taxes?

Payroll taxes are taxes that employers must withhold and pay based on employee wages. These taxes fund federal and state programs and include:

• Social Security tax
• Medicare tax
• Federal Unemployment Tax Act (FUTA)
• Illinois State Unemployment Insurance (SUI)
• Local payroll-related taxes, if applicable

Employers are responsible for withholding the employee portion of Social Security and Medicare taxes from wages, matching these amounts, and remitting both to the IRS. Additionally, employers pay unemployment taxes separately.

What Are Income Taxes?

Income taxes are taxes on individual earnings. In Illinois, this includes:

• Federal income tax withheld from employee wages
• Illinois state income tax withheld from employee wages

Employers must withhold these income taxes from employee paychecks based on IRS and Illinois Department of Revenue withholding tables and remit them accordingly.

Key Operational Differences

• Responsibility: Payroll taxes include both employee and employer portions, while income taxes are withheld from employee wages only.
• Purpose: Payroll taxes fund social programs and unemployment insurance; income taxes fund federal and state government operations.
• Reporting: Payroll taxes require separate filings (e.g., IRS Form 941, Illinois Department of Employment Security reports), whereas income tax withholding is reported on tax returns and W-2 forms.
• Automation: Using payroll software can streamline withholding, payment, and reporting for both payroll and income taxes.

Practical Tips for Illinois Businesses

• Register with the Illinois Department of Revenue and Illinois Department of Employment Security to manage withholding and unemployment taxes.
• Keep accurate payroll records to track tax withholdings and employer contributions.
• Stay updated on tax rate changes and reporting deadlines to maintain compliance.
• Consider integrating payroll tax processing with accounting and bookkeeping systems to reduce errors.

As of 2026, always verify current tax rates and filing requirements with official Illinois and federal resources to ensure operational accuracy.
