Payroll Tax Deadlines for Employers in Maine

Employers operating in Maine must track specific payroll tax deadlines to ensure compliance with state and federal requirements. Timely payroll tax filings help avoid penalties and maintain good standing with tax authorities.

Key Payroll Tax Deadlines

• Federal Payroll Tax Deposits: Employers must deposit federal income tax withheld, Social Security, and Medicare taxes according to their deposit schedule (monthly or semi-weekly). The IRS provides a schedule based on your reported tax liability.
• Maine State Income Tax Withholding: Maine requires employers to remit withheld state income taxes either monthly or quarterly, depending on the amount withheld. Monthly deposits are due by the 15th of the following month.
• Unemployment Insurance Contributions: Maine employers must file quarterly wage reports and pay unemployment insurance taxes. These reports and payments are due by the last day of the month following the end of each calendar quarter (April 30, July 31, October 31, January 31).
• Quarterly Federal Payroll Tax Filings (Form 941): Employers file Form 941 with the IRS by the last day of the month following the end of each quarter (April 30, July 31, October 31, January 31).
• Annual Federal Unemployment Tax (FUTA): Form 940 must be filed annually by January 31 for the previous year’s unemployment tax.
• Annual Wage and Tax Statements (W-2): Employers must provide employees with W-2 forms by January 31 and file copies with the Social Security Administration by the same date.
