Maryland Paycheck Calculator

Five tax lines come out of a Maryland paycheck: federal income tax, Social Security (6.2% up to $184,500), Medicare (1.45%), Maryland state income tax, and Maryland county income tax, which your employer withholds together with the state line. Maryland has no employee-paid payroll premiums in 2026, so anything else on your stub is your own election: 401(k), health premiums, HSA, and similar benefits.

The percentage method annualizes your pay, subtracts a flat $3,400 standard deduction and $3,200 for each exemption on Form MW507, and runs the rest through the withholding schedule: 4.75% up to $100,000 for single filers or $150,000 for joint and head of household filers, then 5.00%, 5.25%, 5.50%, 5.75%, 6.25%, and 6.50% at higher levels. Maryland law bars withholding below 4.75%, so the 2% to 4% brackets on the return never appear on a paycheck. Wages under $5,000 a year have no state withholding at all.

County tax applies to the same taxable amount at the rate for the county of residence on your MW507. Rates run from 2.25% to 3.30%; most counties and Baltimore City use 3.20%, nonresidents pay a special 2.25% rate, and employees who name no county are withheld at 3.30%. Anne Arundel and Frederick use income tiers, which this calculator does not model. Find your county in the Comptroller's Withholding Tax Facts and type the percentage into the Maryland county income tax field; tiered-county residents enter their top applicable rate.

Bonuses paid on their own are withheld at 6.50% plus your county rate. Residents of DC, Virginia, and West Virginia who work in Maryland claim exemption on MW507 line 4; Pennsylvania residents use line 5, which stops state tax only, so county tax is still withheld unless you live in York or Adams County. For 2026 the standard deduction became a flat $3,400 under HB 352, the 6.25% and 6.50% brackets entered the withholding tables, and Allegany rose to 3.20% and Kent to 3.30%.
