Step 1: Collect Employee Information

Every new hire must complete a W-4 (or equivalent in your country), which tells you how much federal income tax to withhold from their wages. This is the foundation of accurate employee payroll taxes.

Step 2: Calculate Withholding on Each Pay Period

Each time you run payroll, you calculate the applicable employee payroll taxes based on their gross wages — including federal income tax, Social Security, Medicare, and any applicable state or local taxes.

Step 3: Match Employer Contributions

As the employer, you're required to match Social Security and Medicare contributions. This is an additional cost on top of the employee's salary a key piece of payroll tax for business that catches many new business owners off guard when budgeting.

Step 4: Deposit Taxes with the Government

Withheld amounts and employer contributions must be deposited on a specific schedule monthly or semi-weekly depending on your business size. Timely deposits are at the heart of payroll tax compliance.

Step 5: File Payroll Tax Returns

Quarterly and annual payroll tax filing is required (Form 941, Form 940, W-2s, etc.). Missing these deadlines is one of the fastest ways to attract IRS attention and payroll tax penalties.
