Employees use Form MW507 to tell their employer how to calculate Maryland withholding from their pay, including exemptions and any additional amount to withhold.

What is the Maryland withholding form called?

The document is Form MW507 — the Employee’s Maryland Withholding Exemption Certificate. Taxpayers submit this document exclusively for payroll purposes — rather than the annual return.

This section supplements the main Maryland forms guide. It details resident & nonresident documents like Form 502 & Form 505 as well as their role in the filing cycle. The guide should be reviewed in the case of assistance in selecting the correct document before tax season.

Who needs Form MW507?

Workers paid through a Maryland payroll system should complete the mentioned Form MW507. The form should be filled in the case of:

  • Beginning a new job
  • Deciding to adjust the paycheck deductions
  • Experiencing a change in the filing status
  • Observing a distinction in the household income
  • Relocating — requiring a review of the state tax profile

Do you send MW507 to the state?

Generally, no. Taxpayers hand Form MW507 directly to their employer's payroll department. The employer retains the document in their records in order to compute the payroll deductions.

Is MW507 the same as the Maryland tax return form?

No. Form MW507 strictly controls payroll withholding. Your annual tax return is a separate filing submitted later to report your total income, taxes paid, and any resulting refund or amount owed.

Form Main use When
MW507 Set Maryland paycheck deductions During employment or after a life event
Form 502 / 505 File Maryland income tax return When submitting the annual return

When should you update the Maryland withholding form?

MW507 should be reviewed whenever a salary item or home life changes. Updating it document lowers the probability of owing a large balance / receiving an oversized refund at taxation. Events that prompt an update can be outlined as below:

  • Marriage or divorcing
  • Taking on a second job
  • Receiving a major pay increase / bonus
  • Relocating to or from Maryland
  • Adding / removing dependents

What should you do if you are not sure how much to withhold?

Taxpayers may start with examining the most recent pay stub & their last filed return. Then, the current paycheck deductions should be compared against the anticipated income for the year. If the math result does not align, it is recommended to have a tax professional analyze the situation before submitting a new MW507.
