Overall, most employers that pay wages subject to federal income tax withholding or Social Security and Medicare taxes file Form 941 each quarter unless they are directed to file a different employment tax return, such as Form 944.

What is Form 941?

Form 941 is the Employer’s Quarterly Federal Tax Return. Specifically, employers use it to report federal payroll taxes for a quarter. Therefore, it is one of the core forms payroll professionals need to recognize because it connects wage payments, tax withholding, employer tax liability, deposits, and quarterly reporting.

First, the 2026 IRS instructions say the March 2026 revision of Form 941 is expected to be used for the second, third, and fourth quarters of 2026 as well.

Deposits are not the same as filing Form 941

A common payroll mistake is treating tax deposits and Form 941 as the same thing. However, they are related but not interchangeable.

Common Form 941 study traps

  • Form 941 is quarterly; Form 940 is annual FUTA.
  • Furthermore, depositing taxes does not replace filing the return.
  • The employer reports both employee and employer shares of Social Security and Medicare tax.
  • Similarly, federal income tax withholding belongs on Form 941, but FUTA generally belongs on Form 940.
  • Consequently, Form 944 filers generally do not file Form 941 each quarter.

How Form 941 fits FPC and CPP study

For FPC prep, focus on recognizing what Form 941 reports and how it differs from Form 940, W-2, and W-4. However, for CPP prep, go deeper into reconciliation, deposit schedules, liability reporting, corrections, credits, and payroll controls around quarterly filing.
