Begin with MW507 and the current employer schedule
Maryland uses its own employee withholding information, including exemptions and applicable state and local details. Federal W-4 credits are not automatically Maryland exemption counts. Review the current MW507 instructions rather than transferring federal entries directly.
The 2026 employer guide provides withholding procedures and state/local schedules. Our Maryland calculator estimates the state portion using the supported employer percentage schedule and entered exemptions. It is a regular resident-wage estimate, not the agency’s full combined state-and-county payroll calculation.

County residence changes the local component
The employer guide instructs employers to use the appropriate local rate for the area where a Maryland resident employee lives. Local rates are not one uniform statewide amount. Certain nonresident situations use separate rules. The state guide and applicable local schedule must be consulted rather than guessing a county amount from the employer’s location.
Our calculator does not automatically select a county, assign its rate, or calculate the local withholding formula. Enter the actual local tax dollars for the paycheck. If the number is unavailable, the resulting net estimate is incomplete to that extent; a blank local field is not evidence that no local tax is due.
When an address changes, notify payroll and check its local treatment. If a check has one combined Maryland tax line, ask for the state and local breakdown before entering the state estimate and the entire combined amount again as local tax.
Withholding exemptions are not your final annual tax deductions
The employer formula uses withholding standard-deduction and exemption adjustments to estimate payroll tax. These are part of the payroll method and should not be assumed to reproduce every deduction, credit, or income adjustment on a Maryland return. A different final tax liability is reconciled at filing.
Use the employer table effective for the wages being paid and the actual certificate on file. The 2026 guide notes that rates can change; an old stub and a current table may not be directly comparable. This site does not offer a historical pay-date engine or substitute annual brackets when a payroll case is unsupported.
Cross-border work and exemption claims need official guidance
Maryland has special rules for nonresidents, reciprocal arrangements, and qualifying exemption claims. Military-related circumstances and other special facts may require additional forms. The resident calculator does not decide eligibility for those treatments.
If residence and work state differ, use the official guide and payroll’s allocation. Do not set withholding exemption merely to force a desired deposit. State income-tax exemption also does not automatically remove federal income-tax withholding, Social Security, Medicare, or employee benefits.

Use the result as a transparent partial calculation
Enter regular gross earnings, frequency, federal elections, Maryland exemptions, and actual deductions. Compare the state income-tax result with the state portion of payroll, then add actual county and other-payroll amounts. The net-pay breakdown should explain which charges were calculated and which were supplied by you.
For a complete check, follow the take-home workflow. For annual filing, consult Maryland’s current return instructions; neither the repeated-check annual projection nor the separate legacy annual-estimate mode is an official 2026 Maryland return calculation.
