Thousands of Frederick County residents commute to Washington, D.C., Northern Virginia, or telework for employers based there. Every one of them faces the same question at tax time: you live in Maryland, you work somewhere else — so where do you actually pay income tax? The answer is simpler than most commuters think, but the withholding mistakes are expensive.
If you live in Frederick County and commute to a job in D.C. or Virginia, your wages are taxed by Maryland — and only Maryland. You pay Maryland state income tax plus Frederick County's local income tax on your full salary, exactly as if your office were on Market Street instead of K Street.
Two separate legal mechanisms produce this result:
Washington, D.C.: Under federal law, the District of Columbia is prohibited from taxing the income of non-residents. It doesn't matter how many days you work in the District — if you're not a D.C. resident, D.C. cannot tax your wages. Your income is taxed by your home state: Maryland.
Virginia: Maryland and Virginia have a reciprocity agreement. Maryland residents who earn wages in Virginia pay income tax only to Maryland, and vice versa. The same reciprocity exists between Maryland and Pennsylvania, West Virginia, and D.C. — covering essentially every jurisdiction Frederick commuters actually work in.
| You Live in Frederick County and Work In… | Who Taxes Your Wages | What You File |
|---|---|---|
| Washington, D.C. | Maryland only | Maryland resident return (Form 502) |
| Virginia | Maryland only (reciprocity) | Maryland resident return; VA exemption certificate with your employer |
| Pennsylvania or West Virginia | Maryland only (reciprocity) | Maryland resident return; exemption certificate with your employer |
| Maryland (fully remote or local) | Maryland only | Maryland resident return |
| A non-reciprocal state (e.g., Delaware, New York) | Both — the work state and Maryland, with a Maryland credit | Nonresident return in the work state + Maryland return claiming the credit on Form 502CR |
The rules are clean. The paychecks often aren't. The most common problem we see with new commuter clients is wrong-state withholding — the employer's payroll system withholding D.C. or Virginia tax instead of Maryland tax.
Here's what should be happening:
Check your pay stub this week, not in April. Look at the state tax line: if it says "DC" or "VA" and you live in Frederick, your withholding is going to the wrong government. You'll eventually get it back — but only by filing a nonresident refund claim — and meanwhile you owe Maryland the full year's tax with nothing withheld toward it. We see commuters hit with a five-figure Maryland balance due plus penalties for a problem one payroll form would have prevented.
We handle these cross-border cleanups regularly as part of our individual tax preparation — including multi-year situations where the wrong withholding ran for several years before anyone noticed.
Post-pandemic, many Frederick "commuters" go into the District or Northern Virginia two or three days a week and work from home the rest. For Maryland residents working for D.C. or Virginia employers, hybrid schedules don't change the answer: as a Maryland resident, Maryland taxes all of your income regardless of where you physically perform the work, and reciprocity (or the D.C. non-resident rule) keeps the work jurisdiction out of the picture.
Where telework does create complexity is the reverse situation — and for employers. If you're fully remote for an employer in a non-reciprocal state, or your employer starts questioning which state's payroll rules apply to your home office days, the analysis gets more involved. And Frederick business owners hiring remote employees who live in Virginia or Pennsylvania have their own reciprocity withholding obligations running the other direction.
Maryland's income tax has two layers — the state tax (up to 5.75%) and the county local tax, which for Frederick County is tiered up to 3.2%. Your local rate is based on where you live, not where you work — specifically, your county of residence on December 31 of the tax year.
This matters in two situations: commuters comparing job offers ("D.C. jobs pay a D.C. premium, but do I pay D.C. taxes?" — no, you pay Frederick's), and anyone who moved during the year, since a mid-year move between counties or across state lines changes which local rate and which returns apply. Part-year resident returns are one of the most error-prone filings people attempt on their own.
Reciprocity covers D.C., Virginia, Pennsylvania, and West Virginia — but not every state. A Frederick resident working in Delaware, or taking a job with required in-office days in New York, faces the two-return situation: a nonresident return in the work state paying its tax, plus the Maryland resident return claiming a credit for taxes paid to other states on Form 502CR. The credit prevents true double taxation, but it has limits — particularly on the local tax layer — and the paperwork is genuinely more complex. If your work state isn't on the reciprocity list, this is worth professional handling.
How we work with commuters: withholding checkups when you start a new job, wrong-state withholding cleanups and refund claims, quarterly estimate schedules when your employer can't withhold Maryland tax, part-year returns for mid-year moves, and multi-state returns for non-reciprocal situations.

Book a ConsultationNo. Federal law bars the District from taxing non-residents' income, no matter how many days you work there. Your wages are taxed entirely by Maryland — state plus Frederick County local tax. If D.C. tax is being withheld from your check, that's an error to fix, not an obligation.
Not if you're Maryland residents. Under the Maryland–Virginia reciprocity agreement, your spouse should file Form VA-4 with their employer claiming the exemption, have Maryland tax withheld instead, and file Virginia Form 763-S to recover what's already been withheld this year.
The state tax rules are the same — as a Maryland resident, your federal salary is taxed by Maryland regardless of whether your duty station is in D.C., Virginia, or a telework arrangement. Federal payroll systems handle Maryland withholding routinely; just confirm your state of residence is set correctly in your payroll profile after any move.
You'll file part-year resident returns in both states for the year of the move — Virginia taxes the income earned while you lived there, Maryland taxes the income from your move date forward, and your withholding needs to switch at the same time. It's a one-year complication, but getting the allocation and withholding transition right avoids paying both states on the same wages.
