IRS Form 941 must be filed four times each year by employers who pay wages subject to payroll taxes. Because it reports payroll tax withholding and employment taxes, the IRS closely monitors whether these returns are filed on time.
But what happens if you miss a Form 941 filing deadline?
When Is Form 941 Due?
Form 941 is filed quarterly. The due dates are:
- April 30 – for wages paid in January through March
- July 31 – for wages paid in April through June
- October 31 – for wages paid in July through September
- January 31 – for wages paid in October through December
If the due date falls on a weekend or federal holiday, the deadline usually moves to the next business day.
Penalties for Filing Form 941 Late
If you fail to file Form 941 on time, the IRS may assess a failure-to-file penalty. This penalty is generally 5% of the unpaid tax per month, up to a maximum of 25% of the unpaid amount.
Even if you cannot pay the full tax owed, filing the return on time can reduce the overall penalties.
Penalties for Paying Payroll Taxes Late
Employers may also face failure-to-pay penalties if payroll taxes are not deposited on time.
The penalty rate can range from 2% of the unpaid deposit if it is only a few days late, up to 15% for significantly late payments. Because payroll taxes include amounts withheld from employees, the IRS takes missed deposits very seriously.
Additional Consequences for Payroll Tax Problems
If payroll taxes remain unpaid or unreported, the IRS may take further collection actions, including issuing IRS notices, assessing additional interest and penalties, or pursuing the Trust Fund Recovery Penalty (TFRP) against responsible individuals.
The Trust Fund Recovery Penalty can make business owners or managers personally responsible for unpaid payroll taxes. Read here for more details on the TFRP.
What Should You Do If You Miss the Deadline?
If you realize that you missed a Form 941 deadline, it is usually best to file the return as soon as possible. Promptly filing the return may limit penalty amounts, prevent additional IRS notices, and help bring the account back into compliance. If multiple quarters were missed, it may be necessary to file several past-due returns to correct the issue.
Final Thoughts
Missing a Form 941 filing deadline can lead to penalties, interest, and IRS notices, especially if payroll taxes were not properly reported or paid. Employers who discover a missed filing should generally submit the overdue return as soon as possible and address any unpaid tax balance to minimize further penalties. Taking prompt action can often help prevent the situation from escalating into more serious IRS collection issues.
