An up-close review of how to complete and file Form 941, including when it’s due and why it’s essential.

What is Form 941?

Form 941 is a quarterly report that gives the Internal Revenue Service (IRS) a snapshot of an employer’s payroll tax liabilities and payments. The 941 tax form shows how much has been withheld from each employee’s wages to pay their income and Federal Insurance Contributions Act (FICA) taxes and how much the employer owes.

What is FICA Tax?

FICA is the collective term for the federal Medicare and Social Security taxes employees and employers owe every pay period. Also known as Old Age, Survivors, and Disability Insurance (OASDI), these taxes fund Medicare and Social Security benefits for employees who are 62 or older.

The 2024 FICA tax rate is 15.3% of each employee’s gross pay until their annual salary or wages reach the wage base limit set by the IRS ($176,100 for 2025). If an employee earns over $200,000 annually, however, they’ll also owe an Additional Medicare Tax of 0.9% on the income that exceeds $200,000.  

Unlike unemployment and income taxes, FICA taxes are split evenly between employees and employers. So, each pay period, an employee only owes 7.65% of their wages in FICA taxes while their employer pays the other 7.65%.

Key Takeaways

  • The federal 941 form tracks how much employees and employers owe in FICA taxes and whether an employee’s income for that year has reached the annual wage base limit.
  • Most employers who withhold FICA taxes from employee wages must file the quarterly 941 form.
  • Employers can file Form 941 electronically or via mail but must do so by the final day of the month following the end of the quarter.

Who Must File a 941 Form?

Generally, any employer who withholds FICA taxes from employee wages must file federal Form 941 every quarter, even if they paid no wages or owed no FICA taxes that particular quarter. There are, however, a few exceptions:

What is Form 941-X?

Form 941-X (Adjusted Employer’s Quarterly Federal Tax Return or Claim for Refund Form) is used to correct a previously filed Form 941 that contained errors, such as misreported wages or tips. It may also, however, be used to retroactively claim certain tax credits (e.g., CARES Act Employee Retention Credits). 

How to Complete Form 941

When preparing to file tax form 941, there are a few pieces of information each employer will need to have, including: 

  • Employee and payroll data (e.g., headcount of paid workers and the wages they earned)
  • Amount owed in FICA taxes that quarter
  • Amount of FICA tax withheld from employee wages that quarter
  • Records of the FICA tax deposits that quarter
