The Maryland Paycheck Calculator estimates your take-home pay after federal income taxes, Maryland state income tax, mandatory county income tax, and FICA contributions. Maryland is unique in requiring every resident to pay both a state income tax (eight brackets from 2% to 5.75%) and a county income tax (piggyback tax ranging from 2.25% to 3.2% depending on county of residence). The combined state-plus-county rate ranges from 4.25% to 8.95%, making Maryland one of the highest total income tax burden states in the country. Maryland's county piggyback tax is mandatory for all 23 counties and Baltimore City. Each jurisdiction sets its own rate annually. Baltimore City levies the highest rate at 3.2%, while several counties are at the minimum 2.25%. The county tax is based on your county of residence, not where you work. This means your total Maryland tax burden depends significantly on where you live. A worker earning $100,000 in Baltimore City pays approximately $3,200 in county tax, while the same worker in a 2.25% county pays $2,250, a difference of $950. Maryland's standard deduction ranges from 15% of gross income with a minimum of $1,800 and a maximum of $2,400 for single filers (minimum $3,600, maximum $4,850 for MFJ). Maryland also provides personal exemptions of $3,200 per person. The state does not conform to the federal standard deduction, using its own calculation. This calculator is essential for Maryland's workforce, which includes large numbers of federal government employees and contractors in the Washington D.C. suburbs (Montgomery and Prince George's Counties), healthcare (Johns Hopkins), military (Fort Meade, Aberdeen Proving Ground, Naval Academy, Andrews AFB), higher education, and the Baltimore metro economy. The dual state-plus-county tax structure makes county selection a critical financial decision for Maryland residents.

- 1Enter your gross pay, pay frequency, and county of residence. Maryland's county tax rate depends on where you live. Montgomery County, Prince George's County, Howard County, and Baltimore City all charge 3.2% (the maximum), while some rural counties charge the minimum 2.25%. Your employer uses your home address to determine the correct county rate.
- 2Federal income tax is calculated based on W-4 elections. Maryland's proximity to Washington D.C. means many workers are federal employees or contractors earning competitive salaries.
- 3Maryland state tax is calculated using eight graduated brackets from 2% to 5.75%. The 4.75% bracket covers the wide range from $3,001 to $100,000, meaning most middle-income earners pay an effective state rate around 4-4.5%. Maryland's standard deduction is calculated as 15% of gross income with minimums and maximums ($1,800-$2,400 single).
- 4County tax is calculated on the same taxable income base at your county's rate (2.25-3.2%). The county tax is separate from the state tax and appears as a distinct line on your pay stub. Combined, the state and county taxes create a total income tax burden of 4.25% to 8.95%.
- 5FICA taxes are calculated at standard federal rates. Maryland has no additional state payroll taxes beyond income and county taxes.
- 6The calculator totals all deductions. Maryland residents working in D.C. or Virginia must also consider multi-state filing, though Maryland provides credits for taxes paid to other states.
- 7Review your results noting the significant impact of county selection. The difference between the highest (3.2%) and lowest (2.25%) county rates is nearly 1 percentage point, which on a $100,000 salary amounts to $950 per year.

Federal government employees and contractors in Montgomery and Prince George's Counties, who commute to agencies in Washington D.C., constitute a huge portion of Maryland's workforce. These workers pay among the highest combined state-plus-county rates (up to 8.95% for high earners in 3.2% counties). The calculator helps them compare living in Maryland versus Virginia, where rates and structures differ significantly.
Johns Hopkins University and Hospital system employees in Baltimore use this calculator to understand their combined Baltimore City and state tax burden. Baltimore City's 3.2% piggyback rate, combined with state rates, creates a total burden that drives some workers to live in surrounding Baltimore County (2.83%) or Howard County (3.2%, but with better public services).
Military and intelligence community employees at Fort Meade, Aberdeen Proving Ground, the Naval Academy, and Andrews AFB use this calculator. Many of these workers have security clearances that require living within a certain distance of their workplace, limiting county selection options. Understanding the tax implications of different nearby counties helps optimize housing decisions within geographic constraints.
Healthcare workers at the numerous hospitals across the Baltimore-Washington corridor use this calculator to compare net pay across different employer locations and residence counties.
D.C. Area Federal Workers Choosing Between Maryland and Virginia
Federal workers in the D.C. area face a critical decision about which state to live in. Maryland's combined state-plus-county rate can reach 8.95%, while Virginia's top rate is 5.75% with no local income tax in most areas (though some localities have modest additional taxes). However, Maryland's property taxes are generally lower than Virginia's in comparable areas. The full tax picture including income, property, and sales taxes should be considered.
Non-Resident Workers in Maryland
Non-residents who work in Maryland must file a Maryland non-resident return and pay both the state tax and a special non-resident tax in lieu of the county tax. The non-resident rate is 1.75%, which is lower than any county rate. This means non-residents working in Maryland actually pay less local tax than residents, creating an incentive for border-area workers to live in D.C., Virginia, Delaware, or Pennsylvania.

Why does Maryland have county income taxes?
Maryland's county income tax (piggyback tax) was established to give local governments a revenue source beyond property taxes. Every county and Baltimore City levies the tax at a rate between 2.25% and 3.2%, set annually by each county council. The tax funds local services including schools, public safety, and infrastructure.
Which Maryland county has the lowest tax rate?
Worcester County on the Eastern Shore has the lowest rate at 2.25%. Several rural counties also have rates near the minimum. The suburban counties around D.C. and Baltimore (Montgomery, Prince George's, Howard) all charge the maximum 3.2%.
If I live in Maryland but work in D.C. or Virginia, which state do I pay?
Maryland residents owe Maryland state and county tax on all income regardless of where they work. If you work in D.C. or Virginia and those jurisdictions withhold their own tax, you can claim a credit on your Maryland return for taxes paid to the other jurisdiction. D.C. and Virginia do not tax Maryland residents who work in their jurisdictions (due to reciprocal agreements or credits), so the net effect is generally paying Maryland rates.
Does Maryland tax retirement income?
Maryland provides a pension exclusion of up to $36,200 per person for qualifying retirement income for those 65 and older. Social Security is exempt from Maryland tax for those with federal AGI under $75,000 (single) or $100,000 (MFJ). Military retirement pay is exempt for those under 55 (partial) and fully exempt for those 55 and older.
Is the county tax based on where I live or work?
The county piggyback tax is based on where you live (county of residence), not where you work. Your employer determines your county rate from your home address. If you move between counties, update your address with your employer to ensure the correct rate is applied.
เคล็ดลับโปร
If you work in the Baltimore-Washington corridor and have flexibility in where you live, the county income tax rate should be a major factor in your decision. The difference between a 3.2% county and a 2.25% county is approximately $950 per year for every $100,000 of taxable income. Over a 20-year period in the same home, that difference exceeds $19,000. Also consider that Maryland provides a credit for taxes paid to other states, so living in Delaware (which has no county income tax) and commuting to Maryland may provide tax advantages for some workers.

Maryland is the only state where every single county and independent city (Baltimore City) is required by law to impose a local income tax. While other states like Indiana have universal county taxes, Maryland's system is unique in combining a mandatory county piggyback tax with one of the steepest state bracket structures in the nation. The combined top rate of 8.95% (5.75% state + 3.2% county) makes Maryland one of the top five highest-tax states for income earners, trailing only California, Hawaii, New Jersey, and New York City (when NYC local tax is included).
