Maryland Paycheck Tax Calculator: How Maryland Withholding Works
A Maryland paycheck calculator has to get two
taxes right: the state tax and the county tax, both figured on the
same taxable wages. On your pay stub they may show as one
SIT or MD state withholding
line or as separate state and local lines. Our
pay stub abbreviations list
explains the other codes.
Federal Withholding for Maryland Paychecks
Federal withholding uses your Form W-4 and the 2026 federal
brackets. The calculator supports filing status, Step 2(c), Step 3
credits and Step 4(a), 4(b) and 4(c). If you claim the new overtime
or tips deductions, our
W-4 Step 4(b) worksheet guide
shows how to enter them, and our
2026 federal tax withholding guide
covers the rest.
Working Across State Lines
Maryland has reciprocal agreements with Pennsylvania, Virginia,
West Virginia and DC. Residents of those places who work in
Maryland can file a MW507 claiming the exemption, and no Maryland
tax is withheld. Delaware isn't on the list, so Delaware residents
working in Maryland pay Maryland state tax plus the 2.25%
nonresident tax. Maryland residents who work in Delaware can ask
for Maryland withholding that's reduced by the Delaware tax their
employer already takes out.
Bonuses
For a lump-sum bonus, the Comptroller tells employers to withhold at
the top state rate of 6.50% plus the top local rate for your county,
so about 9.70% in most of Maryland. Federal withholding (usually a
flat 22%) and FICA apply too. See
why bonuses are taxed so high.
Employer Payroll Costs in Maryland
Employers pay state unemployment insurance
on the first $8,500 of each employee's wages. New employers get a
rate from 1.0% to 2.6%. None of it comes out of your pay. At
year-end, our
W-2 form generator
can use the same wage and withholding totals.
Why Your Actual Maryland Paycheck May Differ
This calculator is a close estimate, not your employer's payroll
run. Your MW507 on file, the county your employer has for you,
rounding in payroll tables, benefit elections, year-to-date wages
and a 27th biweekly payday in some years can all move the result a
little. Maryland's return also uses a slightly different standard
deduction than withholding, so a refund or balance due in April is
normal.
Three-paycheck months
change monthly cash flow but not the tax on each check. For a full
checklist, see why your paycheck is lower than expected.
