How Maryland's Dual Income Tax System Works in 2025

Maryland stands apart from almost every other state because income tax here is not a single levy — it is two separate taxes computed on the same paycheck. Your employer withholds Maryland state income tax based on eight progressive brackets, and then withholds a second, distinct amount for your county or Baltimore City. Both amounts are remitted together to the Comptroller of Maryland, but they are calculated independently and show up as separate entries on a detailed pay stub. Understanding both layers is the only way to accurately project your net pay.

Maryland's Eight State Income Tax Brackets (2025)

Maryland uses one of the more granular progressive structures on the East Coast. For single filers in 2025, the brackets begin at 2% on the first $1,000 of taxable income and climb through rates of 3%, 4%, 4.75%, 5%, 5.25%, and 5.5% before reaching the top marginal rate of 5.75% on income above $250,000. Married filers filing jointly follow a parallel but wider bracket structure that delays bracket creep compared to single filers. Because the brackets compress quickly in the lower and middle ranges, even a median Maryland household income of roughly $90,000 sits solidly in the 4.75%–5% range for state purposes — well above the national average effective state rate.

The County Income Tax: Maryland's Most Distinctive Feature

No neighboring state — not Delaware, not Pennsylvania, not Virginia, not West Virginia — imposes a mandatory county-level income tax the way Maryland does. Every one of Maryland's 23 counties and Baltimore City charges its own local income tax, and your employer is legally required to withhold it based on where you live, not where you work. The rates for 2025 range from a low of 2.25% in Worcester County (on Maryland's Eastern Shore) to a high of 3.20% in several of the state's most populous jurisdictions: Howard County, Montgomery County, and Prince George's County. Most other counties cluster between 2.8% and 3.05%. Baltimore City itself charges 3.20%, matching the highest county rate. If you live in Montgomery County and earn $100,000, your county tax alone accounts for $3,200 of your annual withholding — a figure larger than the entire state income tax bill of a worker in many no-income-tax states.

Maryland's Standard Deduction: A Percentage-Capped System

Unlike the straightforward flat deductions in states like Virginia or the generous deductions in Pennsylvania (which exempts far more income), Maryland's standard deduction is calculated as 15% of your federal adjusted gross income — but it is capped. For 2025, the cap is $2,550 for single filers and $5,150 for married filers filing jointly. This means that once your income exceeds roughly $17,000 (single) or $34,333 (married), your standard deduction stops growing. High earners gain nothing additional from the standard deduction, making itemizing more relevant for Maryland filers than in many other states.

The Personal Exemption Phase-Out

Maryland also provides a personal exemption of $3,200 per filer — a feature that Delaware and West Virginia also offer but that Virginia eliminated years ago. However, this exemption phases out for higher-income Marylanders. Once your income exceeds certain thresholds, the exemption is reduced and eventually eliminated, meaning the highest earners lose this offset entirely. Middle-income workers benefit the most from the full $3,200 exemption, and factoring it into your withholding calculation can meaningfully reduce your state tax bill if you ensure your employer has the correct information on your Maryland MW507 withholding certificate.

How Maryland Compares to Its Neighbors

Virginia's top marginal rate is 5.75% — identical to Maryland's at the state level — but Virginia has no mandatory local income tax layered on top for most workers. Pennsylvania has a flat 3.07% state income tax with local earned income taxes that vary but are not universal and are often lower than Maryland's county rates. Delaware tops out at 6.6% but has no local income tax. West Virginia recently cut its top rate dramatically and is moving toward a flat tax. The result: Maryland's combined state-plus-local burden is consistently among the highest in the Mid-Atlantic region, particularly for residents of its most populous counties.

Practical Advice for Maryland Workers in 2025

• Check your MW507 annually. Maryland's withholding certificate determines how many exemptions your employer uses. Claiming the wrong number can leave you with a surprise balance due or an unnecessarily large refund.
• Know your county rate before accepting a job offer. Moving from Montgomery County (3.20%) to Worcester County (2.25%) cuts your local tax rate by nearly a third — a real consideration for remote workers with location flexibility.
• Pre-tax benefits reduce both taxes at once. Contributions to a 401(k), HSA, or employer health plan reduce your federal AGI, which in turn shrinks Maryland taxable income and applies to both the state and county calculations simultaneously.
• Itemize if your mortgage interest, state/local taxes, and charitable contributions are substantial. Maryland conforms closely to federal itemized deduction rules, and high property values in the DMV area mean mortgage interest deductions are often significant.
