What payroll deadlines should employers track?

Payroll Tax Deadlines for Employers in Massachusetts

Employers operating in Massachusetts must stay on top of several key payroll tax deadlines to ensure compliance and avoid penalties. These deadlines cover federal and state tax obligations related to employee wages.

Federal Payroll Tax Deadlines

• Federal Income Tax Withholding and Social Security/Medicare Taxes (FICA): Deposit schedule depends on your total tax liability. Most employers deposit payroll taxes either monthly or semi-weekly. Use the IRS Electronic Federal Tax Payment System (EFTPS) to submit payments.
• Form 941 - Employer’s Quarterly Federal Tax Return: Due by the last day of the month following the end of each quarter. For example, Q1 (Jan-Mar) is due by April 30.
• Form 940 - Federal Unemployment Tax (FUTA): Annual return due by January 31 for the previous calendar year. Deposit FUTA tax quarterly if your liability exceeds $500.
• Form W-2 and W-3: Provide W-2 forms to employees by January 31 and file W-2s with the Social Security Administration by the same date.

Massachusetts State Payroll Tax Deadlines

• Massachusetts Income Tax Withholding: Deposit frequency depends on your withholding amount. Most employers pay monthly by the 15th of the following month. Larger employers may have semi-weekly requirements.
• Massachusetts Department of Revenue (DOR) Quarterly Return: File Form M-941 by the last day of the month following each quarter to report withheld income tax and unemployment contributions.
• Massachusetts Unemployment Insurance (UI) Contributions: Paid quarterly with the M-941 filing. Deadlines align with the quarterly return due dates.
• Annual Reconciliation: Submit annual reconciliation of Massachusetts income tax withheld using Form M-944 by January 31 of the following year.

Operational Tips for Managing Payroll Deadlines
