Employers must file IRS Form 941 on time, and send it to the correct address, if paper filing. These are incredibly important aspects of filing to stay compliant and avoid penalties.
The correct mailing address for Form 941 depends on the employer’s state and whether or not a payment is included.
What is Form 941?
IRS Form 941 is the Employer’s Quarterly Federal Tax Return and is used by businesses to report various payroll information to the IRS each quarter.
This information includes federal income, social security, and Medicare tax withheld from employee’s paychecks. It also reports the employer’s share of social security and Medicare taxes.
Can I Paper File and Mail Form 941?
The IRS always recommends and encourages electronic filing when possible.
However, businesses may choose to submit their Form 941 filing via physical mail.
Where to mail Form 941 depends on whether a payment is included with the submission and the business address.
Where to Mail Form 941 by State
The table below shows where to mail Form 941 based on state and whether a payment is included.
The US Postal Service (USPS) or a private delivery service (PDS) may be used to mail Form 941. However, it’s important to note that only USPS can deliver to PO Boxes.
If you choose to use a PDS, you must visit IRS.gov/PDSstreetAddresses to ensure that you’re sending your form to the correct address.
