IRS Form 941 for 2020: Simple instructions and PDF download

If you’re an employer that withholds more than $1,000 in Social Security, Medicare, and federal income taxes from your employees’ wages, you’ll need to fill out and submit Form 941, the Employer’s Quarterly Federal Tax Return. This form breaks down how much you’ve withheld from your staffers’ paychecks, as well as how much you’re sending in for the employer portion of Social Security and Medicare taxes. While it’s pretty straightforward overall, there are a lot of lines and boxes to fill in.


Here’s a quick guide to how 941s work and some instructions for completing yours.


What is Form 941?

A 941 return is used to report payroll tax withholdings such as federal income tax plus Social Security and Medicare (typically called FICA) that are withheld from employees’ paychecks. Your Form 941 filing also reports your business’s quarterly contribution to Social Security and Medicare taxes. Keep in mind that 941 reporting is often completed separately from your FICA payments.


When should a 941 be filed?

The deadline for filing your 941 is at the end of the quarter on the last day of the month: April 30, July 31, October 31, and January 31. As a business owner, once you file your first 941 once, you must file the form quarterly, even if you have no taxes to report. If your business closes, you also have to file a final return for the year the business closed.


Based on how much you’ve withheld for taxes, your company will be a monthly or semi-weekly depositor, and all payments must be made through the Electronic Federal Tax Payment System. If your taxes due are less than $2,500, you can pay them with the return, but if your tax liability for the quarter is more than $2,500, you will be asked to make a monthly deposit.


How do I know if I need to file a 941?

Depending on how much tax you pay, you may need to file either a 941 or Form 944. For example, if you expect to have tax liability less than $1,000 annually, you may be able to file a 944. If you are a new business owner, you’ll be advised on what form to file when you receive your Employer Identification Number (EIN). If you want to dive a little deeper, we’ve also got detailed instructions for how Form 944 works as well as instructions to complete a 944.
