Form MW-506 is Maryland’s reporting form for Return of Income Tax Withheld. In other words, it documents that you withheld your employees’ estimated income tax liability and remitted these funds to the state. There is no online access to Form MW-506 itself, but there is for other related Maryland withholding forms.
If you don’t qualify for or if you don’t want to go through Maryland’s electronic filing system, the state will send you a coupon booklet of Form MW-506 that you can use to fill out and file the information. As a matter of fact, it’s not a bad way to do it—especially if you have software support to help your prepare and print the information on the coupon book forms. In rare cases in which an employer doesn’t owe any withholding tax, the form information must still be filed, but it can be done so through the easy Telefile system.
With all that said, many of our Maryland business customers use AMS Payroll for their unemployment insurance filings, and then go through the state’s e-file system for the rest of their employer filing requirements.
