Form 941 explained: quarterly payroll tax return deadlines and workflow

Form 941 is the common quarterly federal payroll tax return. Employers use it to report wages subject to federal employment taxes, federal income tax withheld, and employer and employee Social Security and Medicare tax amounts, along with adjustments and deposits.

Form 941 is generally due by the last day of the month following the end of each calendar quarter: April 30, July 31, October 31, and January 31, adjusted when a due date falls on a weekend or legal holiday. If all taxes were deposited on time and in full, the IRS generally provides 10 additional calendar days to file the return.

One of the most important payroll concepts is that payroll tax deposits happen on a deposit schedule that can be monthly or semiweekly, while Form 941 is a quarterly reconciliation return. Filing the return on time does not cure deposits that were due earlier in the quarter.

• Reconcile gross wages and taxable wages to the payroll register.
• Reconcile federal withholding, Social Security, and Medicare to payroll reports.
• Match tax deposits to EFTPS or payroll-provider confirmations.
• Tie payroll expense and payroll liabilities to the general ledger.
• Investigate voids, off-cycle payroll, and prior-quarter adjustments before signing.
