Q: What’s Form 941 and How Do I Fill It Out?

IRS Form 941, the Employer’s Quarterly Federal Tax Return, is how you tell the IRS how much was withheld from your employees’ paychecks each quarter.

Specifically, the quarterly report allows you to detail the withholding amount in income taxes, Social Security, and Medicare, along with your portion of Social Security and Medicare tax. 

This guide will teach you the basics of the 941 form along with detailed instructions to help you fill it out. Keep in mind that some full-service payroll services (like Gusto) fill out and file Form 941 automatically. Check with your payroll provider to see if that’s the case.

Who needs to file Form 941?

Most employers who pay wages to an employee must file Form 941 every quarter. Your business entity doesn’t impact your filing requirements. Regardless of whether you’re a sole proprietor or a C corporation, you’ll need to file Form 941 if you have employees. 

What happens if you don’t have employees for a particular quarter? You’re still required to file Form 941 and report that you didn’t have any tax withholdings. 

In general, businesses with employees are required to file Form 941 every quarter, but there are a few exceptions.

  • Businesses with seasonal employees. If you only hire employees seasonally, then you’re not required to fill out Form 941 every quarter. Instead, you’ll complete Form 941 for the quarter you hired seasonal employees and then inform the IRS that you won’t be filing Form 941 for several quarters. Our instructions below explain how to do this. 
  • People with household employees. If you have a household employee, like a nanny, you don’t need to File 941. Instead, report the tax withholding annually on the Schedule H of Form 1040 (your personal tax return). 
  • Businesses with farm employees. Wages paid for agricultural labor aren’t reported on Form 941. Instead, you’ll use Form 943

Finally, if you received a notification that you’re required to file Form 944 instead of Form 941, then you’re not required to submit Form 941 quarterly (see below for more information on Form 944). 

When do I need to file Form 941?

Form 941 is due on the last day of the month that follows the end of the quarter. For example, the first quarter ends March 31, which means the form is due by April 30. If the filing deadline falls on a weekend or holiday, then the return is due on the next business day. 

If you’ve made your payroll tax deposits on time and in full throughout the quarter, then you have an additional 10 days to complete the form. That changes the deadline to the 10th of the second month following the end of the quarter. For the first quarter, that means you can have until May 10 if needed.

Here’s a breakdown of the Form 941 due dates. 

Months included in quarterQuarter endsForm 941 due dateForm 941 due date with on-time tax deposits
January, February, and MarchMarch 31April 30May 10
April, May, and JuneJune 30July 31August 10
July, August, and SeptemberSeptember 30October 31November 10
October, November, and DecemberDecember 31January 31February 10

What happens if I don’t file Form 941 on time?

Late 941s can lead to penalties and interest, so make sure you file the form by the last day of the month every April, July, October, and January. 

The penalty for filing Form 941 late is 5% of the tax due with the form for each month, or portion of the month, that the form is late. 

What information do I need to file Form 941?

You’ll need your Employer Identification Number (EIN), the legal name you used to apply for the EIN, and your company address. Your business name and EIN will be on every page of the form and any attachments you include.

You’ll use the form to report the following items, so you’ll also need this information on hand before completing the form:

  • Wages you’ve paid your team
  • Tips your employees reported to you
  • Federal income tax withheld
  • Group term life insurance premiums paid for employees
  • Sick pay paid to employees
  • Tips earned
  • Your employee’s share of Social Security and Medicare taxes (and yours)
  • The current quarter’s adjustments to Social Security and Medicare taxes
  • Additional Medicare tax withheld from employees

What information do I not report on Form 941?

You only use Form 941 for reporting tax withholdings on employee wages. This means you shouldn’t report nonpayroll withholding on Form 941. These include employee backup withholding and income tax withholding for:

  • Pensions
  • Annuities
  • Gambling wins

Instead, you’ll use Form 945 to report these. 

Where do I file Form 941?

Rejoice! You can file Form 941 online, and the IRS encourages you to do so. You can submit Form 941 electronically with E-File.

If you prefer to download the form and fill it out digitally, then you can fill out the form and submit it via mail. Page 6 of the IRS instructions for Form 941 has a table indicating where to send your form. 

If you’re mailing your form, follow these guidelines:

  • Use 10-point Courier font if possible.
  • Don’t use dollar signs or decimal points. Instead, use the preprinted decimals on the form. Don’t round up to whole numbers. You should always write out the cents, even if it’s zero. 
  • Commas are optional.
  • If the value of a field is zero, then leave it blank. The exceptions are lines 1, 2, and 12. These fields must have a zero written in them. 
  • To denote negative numbers, use a minus sign. If you can’t use the minus sign, then use parentheses. 
  • Write your EIN, “Form 941,” and the tax year and quarter on all attachments. 
  • Staple sheets together in the upper left corner. 

Do I send in a payment with Form 941?

That depends on your tax deposit schedule. 

You’re only allowed to send payment with Form 941 if your total tax due is less than $2,500 for the current quarter and was also less than $2,500 for the previous quarter. Then you can send your payment with the Form 941-V payment voucher. 

If this doesn’t apply to you, then you must pay your tax liability online. 

What’s the difference between Form 941 and Form 944?

Form 944 is for smaller employers, whose annual tax liability is less than $1,000 for Social Security, Medicare, and withheld federal income tax. These employers will file Form 944 annually instead of every quarter. 

If your employer tax liability and withheld federal income tax is more than $1,000 per year, then use Form 941 and file it quarterly.

What about Schedule B on Form 941? Do I need to fill that out?

Schedule B is only required for employers who deposit their payroll taxes on a semi-weekly payroll schedule. You’re required to deposit your payroll taxes semi-weekly if you reported more than $50,000 in taxes during the lookback period. 

A lookback period is a 12-month period that covers four quarters and always ends on June 30 of the previous year. For example, in 2020 the lookback period is July 1, 2018 – June 30, 2019. 

If you’re required to deposit your payroll taxes on a semi-weekly basis, then you’ll complete Schedule B and attach it to your Form 941. Schedule B reports your daily payroll tax liabilities and total tax liability for each month in the filing period. 

Form 941 instructions

First, you’ll need to provide the IRS with some basic information about your business:

  • 1. Enter the number of employees on your payroll for the quarter. Payroll includes wages, tips, commissions, and employee bonuses. Be sure to include the payroll periods of March 12, June 12, September 12, and December 12 for their corresponding quarter. Don’t include employees whom you didn’t pay during the quarter. 
  • 2. Enter the total wages, tips, sick pay, commissions, and bonuses paid to all your employees during the filing period. 
  • 3. Write the total amount of federal income tax that you withheld, or were required to withhold, from your employee’s wages. When calculating the federal income tax withheld, include withholdings on taxable fringe benefits and supplemental unemployment compensation benefits. 
  • 4. Check this box if you had no wages or other compensation subject to Social Security or Medicare tax. If this doesn’t apply to you, then leave the box blank.  
Form 941 instructions_3
  • 5a. 
    • Column 1: Write the total taxable wages, sick pay, and fringe benefits subject to Social Security tax that you paid to employees during the quarter. Enter the amount before deductions. If an employee has earned more than $132,900 for the year, which is the Social Security wage base, then don’t enter their wages on line 5a. 
    • Column 2: Multiply the amount you entered in column 1 by 0.124. Enter the total here. 
  • 5b.
    • Column 1: Put the total amount of tips your employees received during the quarter, even if you were unable to withhold employee tax from the tips. Later, you’ll reduce your taxes by the amount of the employee’s share of the taxes on the uncollected tips. 

If an employee earned more than $132,900 in wages and tips for the year, don’t include their tips on this line. 

  • Column 2: Multiply the amount you entered in column 1 by 0.124. Put the total here.
  • 5c.
    • Column 1:  Put the total taxable wages, sick pay, and fringe benefits subject to Medicare tax for the quarter. There is no limit for wages subject to Medicare tax.

Form 941 instructions_5
  • 5e. Add the amounts from column 2 on lines 5a–5d. 
  • 5f.  If you received a Section 3121(q) Notice and Demand, enter the tax due here. This document tells you the amount of tips that your employee received that was unreported or underreported to you. 
  • 6. Add lines 3, 5e, and 5f. This is the total tax you owe before any adjustments. 
  • 7. Sometimes the total tax due on Form 941 and the total taxes you deposited may be different due to rounding to the nearest cent each time you completed payroll. The IRS calls the difference “fractions-of-cents” adjustments. 

To determine if you have a fractions-of-cents adjustment, compare the amount for Social Security tax, Medicare tax, and additional Medicare tax on Form 941 with the total Social Security and Medicare taxes withheld from each employee. If there is a small difference, it’s a fraction-of-cents adjustment. 

Write this amount on line 7. If the amount you withheld is less than the amount on Form 941, put a negative number here (use the minus sign). If it’s more, then enter a positive number. 

Form 941 instructions_6
  • 8. If you use a third-party sick-pay payer (insurance company that pays out sick pay for employees on your behalf), then enter the amount of the employee’s portion of Social Security and Medicare taxes that your third-party sick payer deposited and paid. This amount should be a negative number. 
  • 9. Enter a negative number for the total of:
    • The employee share of Social Security and Medicare tax on tips 
    • The employee share of Social Security and Medicare taxes on group-term life insurance policies paid for former employees 
  • 10. Add lines 6–9. Put the total here. 
  • 11. This line is for employers claiming the payroll tax credit for increasing research activities, called the Research and Development Tax Credit. If you’re claiming this credit, then write the amount from line 12 of Form 8974 and attach this form to Form 941. 
Form 941 instructions - Lines 12-15
  • 12. Subtract line 11 from line 10. The difference is your quarterly tax liability. 
  • 13.  Enter your total deposits for the quarter as well as any overpayments you made in previous quarters. 
  • 14. If your total tax liability is more than your deposits, you’ll enter that amount here. To calculate this, subtract line 13 from line 12. If the number is more than zero, enter it on line 14. 

If line 14 is under $1, you don’t have to pay your balance. If your balance is more than $1, then you can pay the amount due online at the Electronic Federal Tax Payment System, or EFTPS. 

  • 15. If you overpaid your tax deposits, enter the amount here. To calculate your overpayment, subtract line 13 from line 12. If the amount is less than zero, enter it on line 15. 

If you have an overpayment, choose whether you want the IRS to refund you or apply your overpayment to the next quarter. 

Part 2

Part 2 Form 941 instructions
  • 16. Check one of the following boxes:
    • Box 1. Check the first box if all of the below are true. If you check this box, you can send in your tax payments when you file Form 941.

Part 3 Form 941 instructions

Part 3 only applies to you if:

  • You closed your business.

Finally, enter a five-digit PIN that the person will use when speaking to the IRS. 
  • No. Check the second box if you don’t authorize the IRS to speak to another person about your return.

    If I may make a suggestion – I would include the fact that Gusto files this form for you if you have an account with them. I started filling it out and later realized it had already been filed by checking [GUSTO > Documents] on my account.

    • Micah Boak

      Thanks for the helpful comment. I was wondering the same thing.

  • Nancy

    I’m trying to figure out where in Gusto I can find my 941 forms that were filed by Gusto?
