DC Income Tax Calculator

How to Use This DC Income Tax Calculator

This DC income tax calculator estimates your annual Washington DC and federal tax liability for 2025 and 2026. Enter your gross wages, filing status, and any pre-tax deductions above. DC applies progressive brackets from 4% to 10.75% after the standard deduction and $4,150 personal exemption.

Note for Maryland and Virginia residents: If you live in MD or VA and work in DC, you likely owe income tax to your home state, not DC, due to reciprocity agreements. Use the Maryland paycheck calculator or Virginia paycheck calculator instead. For per-paycheck withholding, use the DC paycheck calculator.

Washington DC Income Tax Brackets

DC uses seven progressive brackets — more granular than most states. The same brackets apply to all filing statuses (single, MFJ, MFS, HOH). Key brackets to know for middle-income earners:

• 4.00% on the first $10,000 of DC taxable income
• 6.00% on $10,000–$40,000
• 6.50% on $40,000–$60,000
• 8.50% on $60,000–$250,000 — the bracket most DC middle-income earners are in
• 9.25% on $250,000–$500,000
• 9.75% on $500,000–$1,000,000
• 10.75% on income above $1,000,000

The 8.5% rate kicking in at only $60,000 of taxable income (after deductions) means many middle-income DC residents see a significant portion of their income taxed at 8.5%. In practice, a single resident earning $80,000 has $81,250 in DC taxable income (after $18,750 in deductions/exemptions), with most income in the 8.5% bracket.

DC Residency, Reciprocity, and Who Owes DC Tax

Washington DC's income tax jurisdiction is unique because DC is not a state — it is a federal district. Understanding who owes DC tax matters:

• DC residents: Pay DC income tax on all worldwide income, filed annually on Form D-40.
• Maryland residents working in DC: Under the DC-Maryland reciprocity agreement, Maryland residents who earn wages in DC pay Maryland income tax only — not DC income tax. Their employers must withhold MD tax on their DC wages if they file DC Form D-4A (Certificate of Non-Residence in DC).
• Virginia residents working in DC: Same reciprocity arrangement — Virginia residents working in DC pay Virginia income tax, not DC income tax.
• All other non-residents: Workers from states other than MD and VA who earn wages in DC generally owe DC non-resident income tax on DC-sourced wages, filed on Form D-40B.

Step-by-Step Example — $100,000 DC Resident Single Filer (2026)

1. Gross wages: $100,000
2. Federal standard deduction: −$16,100 → federal taxable income: $83,900. Federal income tax: ≈ $13,170.
3. FICA: $100,000 × 7.65% = $7,650.
4. DC standard deduction: −$14,600
5. DC personal exemption: −$4,150 → DC taxable income: $81,250
6. DC income tax: 4% × $10,000 ($400) + 6% × $30,000 ($1,800) + 6.5% × $20,000 ($1,300) + 8.5% × $21,250 ($1,806) ≈ $5,306
7. Total taxes: $13,170 + $7,650 + $5,306 = $26,126
8. Annual net income: $100,000 − $26,126 = $73,874

DC Earned Income Tax Credit and Other Credits

Washington DC offers several tax credits that can significantly reduce annual DC tax liability:

• DC Earned Income Tax Credit: 40% of the federal EITC — the most generous local EITC rate in the United States. Fully refundable. For a family with three children earning $30,000, this can mean a DC refund of $2,600+ in addition to the federal credit.
• DC Low-Income Credit: A refundable credit for very low-income residents with DC AGI below $20,000.
• DC Property Tax Credit:DC's Schedule H credit for renters and homeowners with income below $57,600 — up to $1,275 in credit to offset rent or property taxes.
• DC College Savings Deduction: Contributions to the DC College Savings Plan (DC529) are deductible from DC income — up to $4,000 per account per year (single) or $8,000 (MFJ).

How to Reduce Your DC Annual Tax Liability

• Maximize traditional 401(k) contributions— $23,500 in 2026 ($31,000 if age 50+). At DC's 8.5% rate, maxing a 401(k) saves approximately $1,997 in DC income tax per year.
• Contribute to an HSA — $4,300 (self-only) or $8,550 (family). Reduces both federal and DC taxable income.
• File for the DC EITC — if eligible, ensure it is claimed on your D-40 return. It is refundable and often unclaimed by eligible DC residents.
• Update DC Form D-4— DC's withholding certificate. Claim the correct personal and dependent exemptions to ensure accurate withholding.

This calculator provides estimates for informational purposes only. It is not tax advice. DC income tax brackets, standard deduction amounts, personal exemption amounts, and reciprocity rules change periodically. The reciprocity information described above reflects general guidance as of 2026 — Maryland and Virginia residents who work in DC should confirm their withholding status with their employer's HR department or a qualified tax professional.
