Our DC income tax calculator 2026 uses the exact same mathematical formulas as DC Form D-40 (Individual Income Tax Return) and incorporates all 2026 projected tax brackets, standard deductions, and DC-specific credits. The calculations are identical to what the DC Office of Tax and Revenue uses, with the main difference being that ours provides instant estimates while the official forms require manual entry.
Federal Tax: Uses IRS brackets (10% to 37%), standard deduction ($14,600 Single), and federal rules. DC Tax: Uses DC brackets (4% to 10.75%), DC standard deduction ($13,850 Single), and DC-specific rules like enhanced EITC. DC taxable income starts with federal adjusted gross income but applies DC deductions and exemptions. Our calculator handles both sets of rules appropriately.
Yes, as a nonresident who works in DC, you must file a DC nonresident tax return (Form D-40B) to pay DC tax on your DC-source income. However, you can claim a credit on your Maryland return for taxes paid to DC to avoid double taxation. Our calculator has a "nonresident" option specifically for this situation.
DC's EITC is one of the most generous in the nation. For 2026, it's projected to be 70% of the federal EITC amount (with proposals to increase to 75%). This means if you qualify for a $1,000 federal EITC, you'd receive approximately $700 from DC. The DC EITC is refundable, so you can receive it even if you don't owe DC income tax.
1) Not claiming DC EITC: Many eligible residents miss this valuable credit. 2) Incorrect nonresident filing: Confusion about DC vs home state filing requirements. 3) Missing senior deductions: Taxpayers 65+ often miss the additional $1,500 deduction. 4) Withholding errors: Not adjusting DC withholding after life changes. 5) Quarterly estimates: Self-employed individuals forgetting DC estimated payments.
