Instructions for Form 941 Checklist – 2024 Tax Year
Form 941 reports quarterly federal employment taxes withheld from employee wages and
employer Social Security and Medicare taxes. Employers use this form to document income tax withholding, FICA taxes, and additional Medicare tax collected during each quarter. The 2024 version reflects updated penalty structures, modified deposit rules for certain filers, and revised worksheets for calculating employee retention credit carry-forward amounts from prior years.
Filing Requirements and Due Dates
You must file Form 941 if you pay wages subject to federal income tax withholding or Social
Security and Medicare taxes. The quarterly federal tax return covers four reporting periods
January through March, April through June, July through September, and October through
December.
Each return comes due on the last day of the month following the quarter's end, unless that date falls on a weekend or federal holiday. Employers whose annual employment tax liability totals
$1,000 or less may qualify to file Form 944 annually instead of quarterly Forms 941. Still, the
Internal Revenue Service determines eligibility based on tax liability rather than the number of employees.
Reporting Wages and Income Tax Withholding
Enter all wages subject to federal income tax withholding on line 1a, including taxable tips your employees reported to you. Line 1b captures adjustments for prior-period corrections or administrative changes made during the tax year.
Line 2 requires the total federal income tax withheld from employee paychecks during the quarter. Backup withholding and income tax withholding on nonpayroll payments such as pensions, annuities, and gambling winnings must be reported on Form 945, not Form 941.
Calculating Social Security and Medicare Taxes
Report total wages subject to the 6.2% Social Security tax on line 5a, up to the annual wage base of $168,600 per employee in 2024. Line 5b captures the employer's matching Social
Security tax at 6.2%.
Wages exceeding this threshold remain subject to Medicare tax but are exempt from Social
Security tax. Lines 5c and 5d cover the 1.45% Medicare tax on all salaries with no wage cap, plus the additional 0.9% Medicare tax.
Employers must withhold the additional Medicare tax on wages exceeding $200,000 in a calendar year, regardless of the employee's filing status. The employee's ultimate tax liability may differ based on their filing status when they file their individual tax returns. Still, employer withholding begins at $200,000 regardless of whether the employee files as single, married filing jointly, or married filing separately.
Sick Leave and Family Leave Credits
The IRS removed lines for qualified sick and family leave wages from Form 941 for tax periods beginning after December 31, 2023. Employers who paid qualifying wages in 2024 for an earlier applicable leave period must file Form 941-X after filing Form 941 to claim the credit.
Employee Retention Credit Adjustments
Report Employee Retention Credit carryforwards from prior years on the applicable line if amended filings reduce your 2024 liability. Recent legislation prohibits ERC claims for the third and fourth quarters of 2021 filed after January 31, 2024.
The filing deadlines for earlier periods were April 15, 2024, for 2020 tax periods and April 15,
2025, for 2021 tax periods. Employers claiming prior-year ERC must reconcile any adjustments on the 2024 Form 941.
Deposit Requirements and Payment Rules
Employers with total taxes after adjustments of less than $2,500 for the current quarter or the prior quarter face no deposit requirement, provided they did not incur a $100,000 next-day deposit obligation during the current quarter. These employers must pay the full amount by the
Form 941 due date using the Electronic Federal Tax Payment System or an approved payment method. Employers with tax liability of $2,500 or more for both the current and prior quarters must follow monthly or semi-weekly deposit schedules based on total Form 941 taxes reported during the four consecutive quarters ending June 30 from the previous year.
Schedule B Filing Requirements
For the semiweekly schedule, depositors must complete and file Schedule B with Form 941.
This requirement applies to employers who reported more than $50,000 of employment taxes during the lookback period or accumulated $100,000 or more in tax liability on any given day.
All federal tax deposits must be made through EFTPS or an approved third-party payment processor. Compare total deposits with the total liability reported on Form 941 through your electronic payment records to identify and correct any discrepancies before filing.
Penalties and Corrections
Deposit penalties vary based on how late you make your payment. Two percent applies to deposits made 1 to 5 days late, while 5 percent applies to deposits made 6 to 15 days late.
Ten percent applies to deposits made sixteen or more days late or paid directly to the IRS instead of through proper deposit channels. Fifteen percent applies to amounts unpaid for more than ten days after the IRS issues a notice demanding payment, and only the highest applicable penalty rate applies to each late deposit.
Failure-to-file penalties equal five percent per month, up to twenty-five percent, if you file Form
941 late. Interest on unpaid tax accrues at the applicable federal rate plus three percentage points, compounded daily through the payment date.
Use Form 941-X exclusively to correct errors on previously filed 2024 returns. File Form 941-X in the quarter when you discover the error, referencing all affected periods and the original Form
941.
Recordkeeping Requirements
Maintain all payroll registers, W-4 forms, wage and tax statements, and deposit records for at least four years after filing the fourth quarter for the year. Keep health insurance premium payments and nontaxable fringe benefit documentation with your employment tax records to support potential Internal Revenue Service examinations or Form 941-X corrections.
