DC Tax Brackets 2025-2026 Guide – Washington, D.C. residents and businesses face one of the most progressive state-level income tax systems in the U.S., with rates ranging from 4% to 10.75%. Whether you’re a single filer earning $50,000 or a high-earner making over $1 million, understanding the DC tax brackets for 2025 and 2026 is essential for accurate planning, filing, and minimizing your tax bill.
This comprehensive guide uses the latest official data from the DC Office of Tax and Revenue (OTR) and trusted sources. It covers everything USA taxpayers in the District need to know—no changes to the core income tax brackets occurred between 2025 and 2026, making planning straightforward.
DC Income Tax Brackets for 2025 and 2026
The District of Columbia uses the same progressive tax brackets for tax years 2025 and 2026 (and they have remained unchanged since tax year 2022). Unlike the federal system, DC brackets do not adjust for inflation and apply identically regardless of filing status (single, married filing jointly, head of household, etc.).
Here are the official DC tax brackets:
| Taxable Income | Tax Calculation |
|---|---|
| Not over $10,000 | 4% of taxable income |
| Over $10,000 but not over $40,000 | $400 + 6% of excess over $10,000 |
| Over $40,000 but not over $60,000 | $2,200 + 6.5% of excess over $40,000 |
| Over $60,000 but not over $250,000 | $3,500 + 8.5% of excess over $60,000 |
| Over $250,000 but not over $500,000 | $19,650 + 9.25% of excess over $250,000 |
| Over $500,000 but not over $1,000,000 | $42,775 + 9.75% of excess over $500,000 |
| Over $1,000,000 | $91,525 + 10.75% of excess over $1,000,000 |
Key takeaway for 2025-2026: Your marginal rate only applies to income within each bracket. The top rate of 10.75% kicks in at $1 million+—one of the highest in the nation.
How DC Tax Brackets Work: Progressive Taxation Explained?
DC calculates tax on taxable income (federal adjusted gross income minus DC-specific deductions and adjustments). The system is progressive: lower brackets are taxed at lower rates, and only the income exceeding each threshold is taxed at the higher rate.
Example (2025 or 2026, single filer with $75,000 taxable income):
- First $10,000 → 4% = $400
- Next $30,000 ($10k–$40k) → 6% = $1,800
- Next $20,000 ($40k–$60k) → 6.5% = $1,300
- Remaining $15,000 ($60k–$75k) → 8.5% = $1,275
- Total DC tax ≈ $4,775 (before credits)
Use the official OTR tax rate schedule or tax software for precise calculations.
Standard Deductions in DC for 2025-2026
DC decoupled from certain federal changes in 2025 but maintains its own basic standard deduction amounts. These reduce your taxable income dollar-for-dollar.
For Tax Year 2025:
- Single / Married Filing Separately / Dependent: $15,000
- Head of Household: $22,500
- Married Filing Jointly / Qualifying Widow(er): $30,000
Additional standard deduction (age 65+ or blind):
- $1,600 (or $2,000 if single, head of household, or dependent)
For Tax Year 2026: The basic amounts will receive an annual cost-of-living adjustment (COLA) starting after 2025. Early projections show increases (e.g., approximately $16,100 single / $32,200 joint), but confirm with the 2026 D-40 booklet when released.
Pro tip: Most DC filers take the standard deduction. Itemized deductions are subject to a 5% limitation for higher earners (DC AGI over $200,000 / $100,000 separate).

How DC Taxes Compare to Federal & Nearby States?
