Quick answer

Montgomery County residents pay Maryland's progressive state income tax topping at 6.5% plus a 3.2% county income tax administered by the county. At $85,000 single, the after-tax estimate including state and county is $62,082. MoCo sits at Maryland's statewide cap, the highest tier of county rates.

Montgomery County is Maryland's largest jurisdiction by population and one of the wealthiest counties in the US by median household income. The county levies a 3.2% income tax on resident wages, sitting at the statewide cap alongside Prince George's, Howard, Baltimore County, and Baltimore City. MD's county-tax system means county of residence determines the local rate, and the variance from county to county directly shapes the take-home stack for every wage earner. NIH (the National Institutes of Health main campus in Bethesda), Walter Reed National Military Medical Center, and the FDA (White Oak headquarters) anchor a federal health-research employment base unmatched anywhere else in the US. Discovery Inc. operates its corporate headquarters in Silver Spring; Marriott International keeps its global headquarters in Bethesda; Lockheed Martin runs a Bethesda-based corporate campus. Strathmore performing arts complex and Olney Theatre Center layer cultural employment on top. Residents skew highly educated and ethnically diverse; the Maryland-side WMATA Red Line runs the spine from Shady Grove through Rockville, Bethesda, and on to downtown DC. At $85,000 for a single Montgomery County resident, federal income tax is $9,870, Maryland state tax is $3,826, FICA combined is $6,503, and the county line is $2,720, leaving take-home of $62,082.

Montgomery County, Maryland paycheck FAQ

What is the federal tax bill on $85,000 single in Montgomery County?
The federal income tax owed on $85,000 single is roughly $9,870, with the top slice taxed at the 22% marginal rate after the standard deduction. Federal computation runs identically nationwide, so a Montgomery County single filer sees the same federal line as a counterpart in Howard County or Baltimore City on the same gross.
How much Maryland state tax does someone owe in Montgomery County?
Maryland state income tax at $85,000 single is approximately $3,826, with the schedule topping at 6.5% on the highest incomes. The Montgomery County 3.2% income tax stacks on top of the same Maryland taxable base, producing one of the higher combined state-and-local burdens in the US for top-cap counties.
If I live in Montgomery County but work in DC, what tax applies?
DC does not tax non-resident commuters under federal law, so a Montgomery County resident working at a DC office owes no DC income tax on those wages. Maryland state tax and the Montgomery County 3.2% apply instead. The same rule covers MoCo residents working at any DC-side federal agency, contractor, or nonprofit.
How much does a 401(k) contribution save at $85,000 in Montgomery County?
At $85,000 single in Montgomery County, the combined marginal rate is 26.75% on federal plus Maryland state. Pre-tax 401(k) and HSA contributions reduce federal and Maryland taxable income at that combined rate, and because the county tax piggybacks on Maryland taxable income, each deferred dollar trims all three liabilities together.
What changes for married filing jointly, head of household, or filing separately at $85,000 in Montgomery County?
A joint filer at $85,000 keeps about $66,271, $4,189 more the single-filer figure. Wider federal MFJ brackets and the doubled federal standard deduction drive most of the change. Maryland's MFJ schedule widens upper-bracket boundaries, and the Montgomery 3.2% county tax applies neutrally across all four filing statuses. Head of Household lifts take-home to about $65,004, around $2,922 more than Single, and combined MFS take-home runs about $4,189 less than MFJ.
How does Montgomery County compare to Prince George's County?
Montgomery and Prince George's both sit at the 3.2% statewide cap, so the county-tax line dollar amount is identical between them at the same gross income. The two DC-suburb counties diverge on demographic and economic mix more than the paycheck line: MoCo's federal-health-research and corporate base differs from PG's UMD-plus-Andrews-plus-Beltsville anchor.
