  • Additional 0.9% Medicare for employees earning over $200,000

Federal Unemployment Tax (FUTA)

  • 6% on first $7,000 of wages per employee
  • Reduced by up to 5.4% if state unemployment taxes paid on time

Payroll Tax Deposits

  • Monthly depositor: Deposit by the 15th of the following month
  • Semi-weekly depositor: Deposit within 1-2 business days of payroll
