Form 941

What Is Form 941?

IRS Form 941, the Employer’s Quarterly Tax Form, is an essential tax form for businesses. Unlike individuals who file taxes on a yearly basis, most U.S. employers are required to file quarterly federal tax returns. Businesses who have employees must file Form 941 to report federal withholdings from employees.

Required information includes:

  • Number of employees

  • Total wages paid

  • Any adjustments made for tips, group life insurance, and sick days

  • Federal income tax withheld from each employee

  • All Social Security withholdings

  • All Medicare withholdings

When filing Form 941, companies are also expected to pay the employer portion of social security or Medicare tax. The IRS deadlines for the quarterly forms are April 30, July 31, October 31, and January 31 of each year.

Failure to file a Form 941 in time may result in a penalty of 5 percent of the tax due with that return, and can increase up to 25 percent.

Do You Have to File a 941 if You Have No Payroll?

In general, any employer who withholds taxes from employee payroll checks is required to fill out a 941 four times a year, even if you have no taxes to report. The main exceptions are people who have household employees like housekeepers or maids (filed with a 1040 tax return) and agricultural employers (use Form 943 instead of 941). Employers who have seasonal employees only fill out a Form 941 for quarters in which they paid wages. 

Can You Electronically File Form 941?

Form 941 and associated tax payments can be filed either electronically or by mail. You should choose one or the other method, not use both. The IRS e-file allows you to file your form online, and the Electronic Federal Tax Payment System (EFTPS) is a free service provided by the U.S. Department of the Treasury to make your payment online, after initial enrollment. 

How Do I File Quarterly 941?

If you choose to file your 941 by mail, you can either fill out the form on your computer and print it, or print the form first and complete it by hand (mailing instructions are in the next section). Electronic filing can be done online with the Modernized e-file (MeF) system on
