Maryland Payroll Tax and Registration Guide

To stay in compliance with Maryland’s state payroll tax laws, you’ll need to share specific business and tax details before you can begin running payroll through Beyond. Here’s what you’ll need:

  • Maryland Employer Tax ID and local/state registration numbers
  • Assigned tax rates – These are determined by the Maryland tax agencies based on your company’s characteristics like size and industry
  • Power of Attorney (POA) and TPA authorization – Required by most tax departments so Beyond can submit tax filings and payments on your behalf

 

Keeping this information up to date is essential. Beyond relies on the accuracy of your data to file taxes properly, and any penalties from incorrect or missing information will be the employer’s responsibility.
