What is Federal Tax Form 941?

The Form 941, Employer’s Quarterly Tax Return, is used to report employment taxes. If you own and operate a business with employees, you will need to file IRS Form 941 quarterly. You, the employer, are responsible for withholding federal income tax, social security tax, and Medicare tax from each employee’s salary. This form is also used to calculate the employer's portion of Social Security and Medicare tax.

IRS Penalties for Tax Form 941

Failure to file by deadline will result in a 5% penalty on the tax return for each month the return is late. This penalty caps at 25%. The IRS will also heavily penalize you for late payment or not paying the full amount owed. You will be charged 2-15% of the unpaid tax determined by the number of days it remains unpaid.

Late deposit penalty amounts are determined using calendar days, starting from the due date of the liability.
