District of Columbia State Income Tax Guide (2026)

DC's bracket schedule is aggressive relative to where the brackets are positioned. The 8.5% bracket kicks in at just $60,000 of taxable income — earlier than almost any state's near-top threshold. By comparison: NY's 8.82% bracket kicks in at $215K (single); CA's 9.3% bracket kicks in at $69K but effective rates are dampened by the larger standard deduction and more bracket levels. DC's 8.5% at $60K is the line item that surprises new residents the most. The 9.25% / 9.75% / 10.75% top brackets above $250K / $500K / $1M target the BigLaw partner / federal lobbyist class — relevant at those income levels but applying to a small fraction of DC filers.

What a typical filer actually pays: take a $130,000 single federal contractor working at a Fortune 500 firm's DC office, living in Logan Circle. DC taxable income, after the $16,100 federal-conforming standard deduction, is $113,900. DC tax across brackets: 4% on first $10,000 + 6% on next $30,000 + 6.5% on next $20,000 + 8.5% on remaining $53,900 = roughly $7,582. Effective state-equivalent rate on gross: about 5.8%. The headline says 8.5%; the math says 5.8% at $130K because the lower brackets pull early-income tax down. At $200K the effective rate creeps to 7.0%; at $300K, 7.7%; at $500K, 8.4%; at $1M+, 9.2%+.

DC is among the cleanest state-level filings: federal AGI conforming, federal-standard-deduction conforming ($16,100 single / $32,200 MFJ for 2026), no city / county / neighborhood income tax beyond the DC level. The Form D-40 is mostly federal AGI carried down with a small set of DC adjustments. If you've ever filed in Pennsylvania (with the Local EIT), DC feels suspiciously simple.

If you ask a DC homeowner about taxes, they'll talk about the recordation tax and the residency reciprocity question — not the income tax. DC's effective property tax rate averages 0.55% on Class 1 (residential primary residence) — among the lowest in the country. The structural reason is simple: roughly 30% of DC's land is tax-exempt federal property (the National Mall, federal buildings, embassies, military installations), so the residential and commercial tax base shoulders proportionally less. A $750,000 home in Logan Circle pays roughly $4,100/year property tax. The same home in Bethesda MD ($750K assessed) pays roughly $7,600. In Arlington VA, $7,800. DC's residential property tax is the single most underrated structural advantage of DC residency.

The DC homestead deduction is $87,050 for 2026 (indexed annually per DC Code § 47-850), reducing assessed value for Class 1 primary residences. A $750K home with the homestead deduction is taxed as if it were a $663K home — saving roughly $735/year at the 0.85% Class 1 rate. The deduction stacks with the senior assessment cap (for residents 65+ with income below $156K, frozen at acquisition assessment) and the disabled / disabled-veteran exemptions. File Form FP-100 with the Office of Tax and Revenue — typically handled at closing by the title company but verify, especially for properties acquired through inheritance or family transfer.

Real estate recordation tax (1.1% on transactions $400K+, 1.45% on transactions $400K+) plus transfer tax (1.1% / 1.45% same brackets) total 2.2%–2.9% combined on most DC home purchases. The 2.55% combined on a $750K purchase is roughly $19,000 of friction at closing — split between buyer and seller per local practice (frequently the buyer pays recordation, seller pays transfer, but negotiable). Stack these on top of typical 1%–1.5% title insurance plus 4%–5% real estate commission and DC closing costs run materially higher than NoVa or Maryland equivalents. Factor into purchase math; the long-term low property tax substantially offsets but the transaction friction is real.

The DC metro residency choice between DC, NoVa (Arlington / Alexandria / Fairfax), and Maryland (Bethesda / Silver Spring / Rockville) is the most consequential single financial decision most professionals in the metro will make. Run the math:

If you earn $80K+ and you're not doing most of these, you're leaving real money on the table. None of this is exotic. Most of it requires 30 minutes of setup once a year and discipline the rest of the year.

DC has the third-densest professional services market in the country (after NYC and Bay Area), with substantial federal worker, federal contractor, lobbyist, BigLaw, trade-association, and think-tank employment. Tax rates are moderate-to-high but the property tax is genuinely low (0.55% effective on Class 1 residential), and the DC-NoVa-MD reciprocity arbitrage is the single most consequential residency decision in the metro. The hard parts are the 8.5% bracket kicking in at just $60K of taxable income (earlier than almost any state's near-top threshold), the estate-tax exemption at $4,873,200 (well below federal), and the 2.55% combined recordation + transfer tax on home purchases.

Run your numbers in the calculator at the top of this page. DC's calc engine reflects the 7-bracket schedule with the 10.75% top tier added in 2022. Most working professionals see 6.0%–7.5% effective state-equivalent rate at typical comp ($80K–$240K).

If you're a Virginia, Maryland, or Pennsylvania resident working in DC, file Form D-4A with your DC employer to claim Wage Tax Compact reciprocity. DC withholding stops; you pay only home-state tax. The form takes ten minutes and the savings start immediately on the next paycheck.

If you own a home in DC, verify the homestead deduction (Form FP-100 with the Office of Tax and Revenue) is on file — typically handled at closing but exceptions occur with inheritance and family transfers. Max your 401(k) or TSP, capture the DC College Savings Plan deduction if you have kids. If you're an HNW BigLaw partner or federal contractor executive with $5M+ assets approaching retirement, the Virginia or Florida residency conversation with an estate attorney experienced in DC exit-domicile is consequential — DC estate tax exposure at $15M assets runs $1.5M+ that Virginia or Florida would not touch.
