Understanding IRS Form 940 and 941: Deadlines, Filing, and Penalties

IRS Form 940 and 941 are essential employer tax documents with distinct purposes, filing schedules, and penalties for late filing or balances due. Employers must understand what each form does, when it is due, and how to avoid costly mistakes or penalties.

What Is IRS Form 940?

Form 940, officially known as the Employer’s Annual Federal Unemployment (FUTA) Tax Return, reports federal unemployment taxes. The FUTA tax provides funds for paying unemployment compensation to workers who have lost their jobs. Only employers pay FUTA tax; employees do not contribute or have amounts withheld from wages for this tax. The tax is calculated based on the first $7,000 of each employee’s wages annually. Some employment types and payments are exempt from FUTA tax and should be subtracted before calculating the owed amount.

Employers must file Form 940 if they pay $1,500 or more to any W-2 employee in a calendar year or employ at least one worker for part of a day in 20 or more weeks of the year. Special rules apply for businesses employing workers in multiple states or in credit reduction states, requiring Schedule A for accurate calculation.

What Is IRS Form 941?

Form 941, the Employer’s Quarterly Federal Tax Return, is used to report withheld federal income tax, Social Security, and Medicare taxes, along with the employer’s FICA contributions. This form summarizes the payroll tax obligations for each quarter, including reporting on employee tips, federal withholdings, and adjustments for sick pay or payroll credits.

Generally, any business with employees must file Form 941 quarterly, unless instructed by the IRS to file Form 944 annually, which is less common after 2025.

Filing Deadlines for Form 940 and Form 941

Form	Frequency	Due Dates
Form 940 (FUTA)	Annual	January 31 each year, or February 10 if all deposits were made on time
Form 941 (Payroll)	Quarterly	April 30, July 31, October 31, January 31 (applies to the previous quarter)

Be sure to file by these deadlines. For each, the IRS grants a 10-day grace period if all required taxes are deposited on time.

Penalties for Late Filing or Balance Due

Form 940 Penalties

• Penalty of 5% of the unpaid FUTA tax per month (or part thereof), up to 25% maximum.
• Late payment penalties grow depending on the delay: 2% (1-5 days late), 5% (6-15 days late), up to 10% or 15% for longer delays.
• Interest accrues on unpaid amounts until fully paid.

Form 941 Penalties

• Penalty of 5% of unpaid payroll tax per month (or part thereof), capped at 25% of the tax due.
• Minimum penalty is $435 or 100% of unpaid tax (whichever is less) if filed over 60 days late.
• Interest is compounded from the original due date and can accumulate quickly.
• Failure to deposit payroll taxes leads to penalties from 2% to 15%, with risk of liens or legal action for persistent non-payment.

If You Don’t File or Pay On Time

The IRS automatically issues penalty notices and applies interest to tax debts for late filings or payments. Continued noncompliance can escalate to tax liens, levies, and even legal action against your business. Unresolved obligations severely impact business finances and operations, potentially leading to criminal charges in extreme cases.

Avoiding IRS Penalties

• Track and mark IRS deadlines for Form 940 and 941 in advance.
• Deposit all payroll and unemployment taxes on time.
• File electronically when possible to avoid late or lost forms.
• Consult payroll or tax professionals if you’re unsure about deadlines or calculations.
• Respond promptly to all IRS notices—even if you cannot pay in full right away.

Best Practices for IRS Form 940 and 941 Compliance

• File Form 940 annually by January 31 or February 10 if deposits are timely.
• File Form 941 quarterly, by the last day of the month after each quarter, or within the 10-day grace period after timely deposits.
• Deposit payroll and FUTA taxes on schedule and keep accurate records for at least four years.
• Complete supporting schedules accurately and retain records of all filings and deposits.
