Delaware Personal Income Tax Brackets for 2026
Delaware uses a graduated (progressive) state income tax system with seven brackets. Unlike most states, the brackets and rates are identical for all filing statuses—single, married filing jointly, head of household, or married filing separately.
Here are the official Delaware state income tax brackets for tax year 2026 (unchanged from prior years, with the top rate applying to taxable income over $60,000):
| Taxable Income Range | Tax Rate | Tax Calculation Formula |
|---|---|---|
| $0 – $2,000 | 0.00% | $0 |
| $2,001 – $5,000 | 2.20% | 2.2% of excess over $2,000 |
| $5,001 – $10,000 | 3.90% | $66 + 3.9% of excess over $5,000 |
| $10,001 – $20,000 | 4.80% | $261 + 4.8% of excess over $10,000 |
| $20,001 – $25,000 | 5.20% | $741 + 5.2% of excess over $20,000 |
| $25,001 – $60,000 | 5.55% | $1,001 + 5.55% of excess over $25,000 |
| $60,001 and above | 6.60% | $2,943.50 + 6.6% of excess over $60,000 |

The maximum marginal rate remains 6.60%. Delaware has not implemented proposed higher brackets for high earners as of April 2026.
How Delaware Calculates Taxable Income?
Delaware starts with your federal adjusted gross income (AGI) and makes specific state adjustments. Key points for US taxpayers:
- Standard Deduction: $3,250 for single, head of household, or married filing separately; $6,500 for married filing jointly. Add $2,500 per qualifying person (age 65+ or blind) if using the standard deduction.
- You may itemize instead, but Delaware follows federal rules with limitations.
- Common subtractions include Social Security benefits (fully exempt) and certain retirement contributions.
- Delaware does not have a personal exemption.
Taxable income = Federal AGI – Standard or itemized deductions – Delaware-specific subtractions.
Step-by-Step Example: Calculating Delaware State Income Tax
Let’s say you’re a single filer with $75,000 in Delaware taxable income for 2026:
- First $2,000 → 0% = $0
- Next $3,000 ($2,001–$5,000) → 2.2% = $66
- Next $5,000 ($5,001–$10,000) → 3.9% = $195
- Next $10,000 ($10,001–$20,000) → 4.8% = $480
- Next $5,000 ($20,001–$25,000) → 5.2% = $260
- Next $35,000 ($25,001–$60,000) → 5.55% = $1,942.50
- Remaining $15,000 (over $60,000) → 6.6% = $990
Total Delaware state tax: Approximately $3,933.50 (plus any applicable local taxes).

Delaware Corporate Income Tax Rate
Delaware remains a top choice for business incorporation thanks to its simple corporate tax structure:
- Flat rate: 8.7% on federal taxable income allocated and apportioned to Delaware (using a three-factor formula: property, wages, and sales).
- No graduated corporate brackets.
- Businesses also pay a gross receipts tax (rates vary by industry; check current schedules on the Division of Revenue site).
Delaware has no state corporate alternative minimum tax in most cases.
Other Key Delaware Taxes US Residents Should Know
Delaware stands out for its low overall tax burden:
- Sales Tax: 0% statewide (one of only five states without a sales tax).
- Property Tax: Effective rate of about 0.50% on owner-occupied housing—one of the lowest in the nation.
- Local Income Tax (Wilmington only): Residents and workers in Wilmington pay an additional city wage tax (approximately 1.25% on earned income; confirm current rate with the City of Wilmington).

These features make Delaware especially attractive compared to high-tax states like California or New York.
