If you own a small or mid-sized business in the U.S. and have employees, IRS Form 941 is one of the most important payroll tax forms you’ll file. It tracks the federal income tax and employment taxes you’ve withheld, and keeping up with it is essential to avoid penalties and maintain financial stability.

Q2 | Apr 1 – Jun 30 | 31-Jul |
Q3 | Jul 1 – Sep 30 | 31-Oct |
Q4 | Oct 1 – Dec 31 | 31-Jan |
Late filing or payment can result in penalties of up to 25% of the unpaid tax, plus interest.
