Payroll Tax Basics for Small Business Owners

A straightforward guide to payroll taxes, including what employers must withhold, when to deposit, and how to stay compliant with the IRS.

Introduction

Payroll taxes are one of the most important responsibilities for employers. Getting them wrong can lead to IRS penalties, interest, and serious legal consequences. This guide covers what every small business owner needs to know.

What Are Payroll Taxes?

Payroll taxes include:

  • **Federal Income Tax Withholding** — withheld from employee wages based on W-4
  • **Social Security Tax** — 6.2% each from employer and employee (12.4% total)
  • **Medicare Tax** — 1.45% each from employer and employee (2.9% total)
  • **Federal Unemployment Tax (FUTA)** — paid by employer only
  • **State Unemployment Tax (SUTA)** — paid by employer, varies by state
  • **State Income Tax Withholding** — required in most states
  • Employer Payroll Tax Responsibilities

    1. Obtain an EIN

    You need an Employer Identification Number (EIN) from the IRS to report payroll taxes.

    2. Have Employees Complete Form W-4

    The W-4 determines how much federal income tax to withhold from each paycheck.

    3. Calculate and Withhold Taxes

    For each pay period, calculate:

  • Federal income tax withholding
  • Social Security tax
  • Medicare tax
  • State and local taxes
  • 4. Deposit Payroll Taxes

    The IRS requires deposits on a monthly or semi-weekly schedule depending on your total tax liability.

  • **Monthly schedule depositor** — deposit by the 15th of the following month
  • **Semiweekly schedule depositor** — deposit within a few days of payday
  • 5. File Quarterly Returns

    File **Form 941** every quarter to report wages, tips, and taxes withheld.

    6. File Annual Returns

  • **Form 940** for FUTA tax
  • **Form W-2** for each employee
  • **Form W-3** to reconcile all W-2s
  • Common Payroll Tax Mistakes

  • **Misclassifying employees as independent contractors**
  • **Missing deposit deadlines**
  • **Incorrect tax calculations**
  • **Failing to file quarterly returns**
  • **Not keeping adequate records**
  • **Ignoring state and local requirements**
  • Payroll Tax Penalties

    The IRS imposes severe penalties for payroll tax violations:

  • **Failure to deposit** — up to 15% of the undeposited amount
  • **Failure to file** — 5% per month, up to 25%
  • **Trust Fund Recovery Penalty** — 100% of unpaid withholding taxes for responsible individuals
