Work in DC, Live in Virginia: How Taxes Work

Why DC is different

Why does DC not tax nonresidents — and how is that different from reciprocity?

Most states tax nonresidents on income earned within their borders. DC is an exception: it unilaterally does not impose income tax on nonresidents, regardless of their home state. This is broader than a reciprocity agreement, which is a bilateral deal between two specific states. DC's policy means that residents of any state — Virginia, Maryland, California, Texas — who work in DC are exempt from DC income tax.

The historical reason relates to DC's unique status. As the seat of the federal government, the District hosts workers from every state. Taxing all nonresidents would create an administrative and political burden that DC has historically avoided. The result is a clean arrangement: DC taxes only its own residents.

This also means DC does not need separate reciprocity agreements with individual states for wage income. The exemption is universal.

How do I set up withholding with my DC employer as a VA resident?

1. File Form D-4A (Certificate of Nonresidence in the District of Columbia) with your DC employer. This certifies you are not a DC resident.
2. Also provide Virginia Form VA-4 so your employer can calculate and withhold the correct amount of Virginia income tax.
3. Verify your pay stub shows Virginia withholding and zero DC withholding.

If you do not file D-4A, your employer may default to withholding DC income tax, which would mean you overpay DC and underpay Virginia. You would then need to file a DC return to reclaim the DC withholding and pay the Virginia shortfall at year-end.

What if DC tax was withheld from my paycheck by mistake?

This is common when employees forget to file D-4A or when payroll systems default to DC withholding. To recover the money:

1. File D-4A immediately to stop further DC withholding.
2. At year-end, file DC Form D-40B (Nonresident Request for Refund) to reclaim the DC withholding.
3. File Virginia Form 760 as your normal resident return. Pay any VA tax balance resulting from under-withholding.

What if I work some days in DC and some in Maryland or Virginia?

This is a common scenario in the DC metro area. Here is how each combination works for a Virginia resident:

• Days in DC: No DC tax (nonresident exemption).
• Days in Maryland: No MD tax (MD-VA reciprocity — see MD to VA guide).
• Days in Virginia: No additional complexity — you are a VA resident working in VA.

The result: regardless of which jurisdiction you work in on any given day, you owe income tax only to Virginia. This makes the DC-MD-VA tri-state area one of the simplest multi-jurisdictional tax situations in the country, despite being the national capital region.

Why does DC not tax nonresidents — is it a legal restriction?

Yes. The District of Columbia's authority to tax is governed by the DC Home Rule Act, which imposes limits on the District's taxing power. Under this framework, DC does not have the authority to impose an income tax on nonresidents in the same way states do. This is a structural restriction, not a voluntary reciprocity agreement. It means DC cannot unilaterally decide to start taxing nonresidents — it would require a change in federal law.

This distinction matters because a reciprocity agreement can be terminated by either party (as Minnesota did with Wisconsin in 2010). DC's nonresident exemption is more durable — it is built into the legal framework under which the District operates.

Does DC tax any nonresident income at all?

DC does not tax nonresidents on wages and salary. However, DC may tax nonresidents on certain types of DC-source income such as rental income from DC property or business income earned through a DC-based business. If you own rental property in DC, you may need to file a DC return (Form D-40B) for that income even though your wages are exempt.

What about federal employees and military members stationed in DC?

The DC metro area has the highest concentration of federal workers in the country, so this matters for a large number of commuters:

• Federal civilian employees: Treated the same as private-sector workers. DC does not tax nonresidents regardless of employer type. File D-4A and your agency withholds Virginia tax only.
• Active-duty military: Under the Servicemembers Civil Relief Act (SCRA), military members pay income tax only to their state of legal residence, regardless of where they are stationed. If Virginia is your legal residence, you pay VA tax — and DC does not tax you. The SCRA provides even broader protection than the DC nonresident exemption.
• Military spouses: Under the Military Spouses Residency Relief Act, a military spouse can elect to use the servicemember's state of legal residence for income tax purposes, potentially reducing or eliminating state tax.

What if I moved from Virginia to DC mid-year?

If you changed your domicile from Virginia to DC during the year, you become a part-year resident of both jurisdictions:

• For the VA residency period: File Virginia Form 760PY as a part-year resident, reporting income earned while living in Virginia.
• For the DC residency period: File DC Form D-40 as a part-year or new resident, reporting income from the date of your DC residency onward.

Notify your employer at the time of the move. They need to switch from Virginia withholding to DC withholding. DC residents owe DC income tax on all income, so your take-home pay may change noticeably after the move — DC's rates are generally among the higher in the region.
