There is no single, fixed amount or set percentage that applies to everyone. Taxpayers — naturally — aim to have an amount withheld that keeps their Maryland tax return close to break-even. The result varies with the income information, filing status, county & the information presented on Form MW507

The Maryland withholding on the pay stub simply combines state income tax & local tax. The local portion is determined by the location information. The employer relies on the Form MW507 details to calculate this. The Comptroller also presents an online calculator to help you estimate your required withholding.

What changes the amount withheld in Maryland?

Your wages & filing status, exemptions and county dictate the final amount. If you prefer to have more taken out of each paycheck, Maryland’s Form MW507 enables requesting an additional dollar amount per pay period.

Factor Importance
Pay amount & pay frequency Higher wages or bonus payouts increase the withholding
Filing status on MW507 The chosen status alters the payroll calculation
Exemptions claimed Claiming more exemptions lowers the amount withheld
County of residence — or work county for some nonresidents Local tax rates vary with the county
Extra amount requested on MW507 You can direct payroll to take a specific extra amount out of each check

How can you estimate the right withholding fast?

The optimal option is trying the Maryland Comptroller’s withholding calculator. The tool asks for the tax year, payroll frequency, wages, MW507 exemptions, countyand filing status to generate an estimate.

The following items should be ready at the calculation phase:

  • The latest pay stub
  • The most recently filed tax return
  • Estimates for any bonuses / side income
  • The county & filing status
  • The copy of Form MW507 — if you have it

When should you update Form MW507?

Submit a new MW507 in the case that the paycheck setup no longer fits your current life situation. The form instructions recommend reviewing the MW507 annually & after major personal / financial shifts.

Reasons requiring an update can be outlined as below:

  • Marriage or divorce
  • Taking on a second job
  • A spouse beginning or leaving a job
  • Moving to a distinct Maryland county
  • Requesting extra withholding to pay down a tax balance

What if you still owe tax every year?

Put a fixed extra amount on MW507 line 2. Afterwards, the pay stub should be reviewed after a couple of pay periods to see the distinction. A small adjustment can be considered as an optimal method to fix a tax balance without making drastic changes.

In case of working across multiple states or moving during the year — consulting a professional review can be a smart move.
