NOTE: Businesses are required to make federal tax deposits on dates determined by various factors that differ from business to business.

Payroll tax deposits: Employers generally must deposit Form 941 payroll taxes (income tax withheld from employees' pay and both the employer's and employees' share of social security taxes) on either a monthly or semiweekly deposit schedule. There are exceptions if you owe $100,000 or more on any day during a deposit period, if you owe $2,500 or less for the calendar quarter, or if your estimated annual liability is $1,000 or less.

• Monthly depositors are required to deposit payroll taxes accumulated within a calendar month by the fifteenth of the following month.
  
• Semiweekly depositors generally must deposit payroll taxes on Wednesdays or Fridays, depending on when wages are paid.
