Find your Maryland tax account info

Set up an existing company

If you've run payroll in Maryland previously, you can find your eight digit CRN on your Withholding Tax Returns (either Form MW506 or MW508) which you would have received from the Comptroller of Maryland. If you can't find a copy of these forms, you should contact the agency at (410) 260-7980. 

You can find your ten digit Maryland Employer Account Number on any notice received from the MD Department of Labor, Licensing and Registration, Division of Unemployment Insurance. You can also find it on your Unemployment Insurance Quarterly Contribution Report (FORM DLLR/OUI 15) or at the top of your annual tax rate notice that's mailed by the agency in December of each year. 

Unemployment Tax Rate: The Maryland unemployment tax rate ranges from 0.3%–7.5% with a wage base of $8,500. New employers are typically assigned a rate of 2.6% (or 4.8% for construction companies). If you are unsure you should call the agency at 1 (800) 492-5524 and press 1 and then 6.
