Tax & Paycheck Calculators
Maryland Paycheck Tax Calculator
Every Maryland county adds its own mandatory "piggyback" income tax on top of the state rate — based on where you live, not where you work, and there's no opting out.
Calculate your Maryland take-home pay
Federal, FICA, Maryland state tax, and your county's piggyback rate.
The Maryland state bracket schedule here is a close approximation built from multiple public sources, since exact published breakpoints vary slightly by source — treat the state-tax figure as directionally accurate, and confirm your exact number with the Comptroller of Maryland. The county piggyback calculation itself is precise once you enter your correct rate.
Two layers, and the second one is mandatory
Maryland has a graduated state income tax, topping out around 5.75% for the vast majority of filers (a narrower additional tier applies only to a small slice of very high earners above roughly $1 million). But the number that actually drives most Marylanders' total tax bill is the county piggyback tax — a local income tax that every single Maryland county, plus Baltimore City, is required to levy. Unlike Ohio's or Michigan's local taxes, which apply only in specific cities that choose to impose them, Maryland's county tax is universal: there's no county in the state without one, and no way to live in Maryland without paying it.
| County (examples) | Piggyback rate |
|---|---|
| Montgomery, Howard, Prince George's, Baltimore City | 3.2% (the maximum) |
| Most other counties | 2.5% – 3.0% |
| Lowest-rate counties | ~2.25% |
Based on where you live, not where you work
This is the opposite convention from Ohio's municipal tax system: Maryland's county piggyback tax is determined by your county of residence, regardless of which county you actually work in. A Bethesda resident commuting into DC-adjacent Virginia for work still pays Montgomery County's rate; someone living in a lower-rate county but working in Baltimore City still pays their home county's rate, not Baltimore's. Non-residents who earn Maryland-source income pay a flat special nonresident rate (2.25%) instead of any specific county's rate.
The real combined burden
What Maryland doesn't need a separate return for
Despite being a distinct tax administered by the county, the piggyback tax is filed and paid alongside your regular Maryland state return — there's no separate county tax return to complete.
The mandatory, universal, residence-based nature of Maryland's county piggyback tax and its 2.25%–3.2% range are consistently confirmed across multiple independent 2026 Maryland tax guides, including a worked example matching this calculator's mechanics closely. The state bracket schedule is a best-effort reconstruction from public sources with some disagreement on exact breakpoints — confirm precise figures with the Comptroller of Maryland (marylandtaxes.gov) before relying on this for a filing decision.
Frequently asked questions
Before you estimate your Maryland paycheck.
What is Maryland's county piggyback tax?
A mandatory local income tax levied by every Maryland county and Baltimore City, ranging from about 2.25% to 3.2%, applied to the same Maryland taxable income as the state tax and paid alongside your regular state return.
Do I pay county tax based on where I live or where I work?
Where you live. Maryland's county tax is based on residence, unlike some states where local tax follows your work location.
Can I avoid the county tax by living somewhere without one?
No — every Maryland county and Baltimore City levies this tax. The only way to avoid it as a Maryland income earner is to be a nonresident, in which case a flat 2.25% special nonresident rate applies instead.
What is Maryland's top state income tax rate?
Around 5.75% for the vast majority of filers, with a narrower additional bracket reported for a small slice of very high earners above roughly $1 million in taxable income.
Do I need to file a separate return for my county tax?
No. The county piggyback tax is calculated and filed together with your regular Maryland state income tax return.
