This tax calendar covers various due dates of interest to employers. Principally, it covers the following federal taxes.

• Income tax you withhold from your employees' wages or from nonpayroll amounts you pay out.
• Social security and Medicare taxes (FICA taxes) you withhold from your employees' wages and the social security and Medicare taxes you must pay as an employer.
• Federal unemployment (FUTA) tax you must pay as an employer.

The calendar lists due dates for filing returns and for making deposits of these three taxes throughout the year. Use this calendar with Pub. 15 which gives the deposit rules.

Forms you may need - The following is a list and description of the primary employment tax forms you may need.

2. Form 941, Employer's QUARTERLY Federal Tax Return - This form is due the last day of the first calendar month after the calendar quarter ends. Use it to report social security and Medicare taxes and withheld income taxes on wages if your employees aren't farm workers or household employees.
3. Form 943, Employer's Annual Federal Tax Return for Agricultural Employees - This form is due the last day of the first calendar month after the calendar year ends. Use it to report social security and Medicare taxes and withheld income taxes on wages if your employees are farm workers.

Fiscal-year taxpayers - The dates in this calendar apply whether you use a fiscal year or the calendar year as your tax year. The only exception is the date for filing Forms 5500, Annual Return/Report of Employee Benefit Plan, and 5500-EZ, Annual Return of A One-Participant (Owners/Partners and Their Spouses) Retirement Plan or A Foreign Plan. These employee benefit plan forms are due by the last day of the seventh month after the plan year ends. See July 31, later. For more information on filing these forms, go to IRS.gov/Form5500.

Extended due dates - If you timely deposit in full the tax you’re required to report on Form 940, 941, 943, 944, or 945, you may file the return by the 10th day of the 2nd month that follows the end of the return period.

If you’re subject to the semiweekly deposit rule, use Table 2 near the end of this publication for your deposit due dates. However, if you accumulate $100,000 or more of taxes on any day during a deposit period, you must deposit the tax by the next business day instead of the date shown in Table 2.
