Delaware's income tax is graduated: 7 brackets running from 0% to 6.6%, the 13th-highest top rate of the 51 jurisdictions. The top rate applies to a single filer's taxable income above $60,000. A single filer's first $2,000 of taxable income is taxed at 0% — on top of whatever the state lets you deduct first. Married couples filing jointly are taxed on exactly the same bracket widths as a single filer, so a two-earner couple hits the top rate at the same income one person would — the schedule itself carries a marriage penalty. A single filer subtracts a $3,250 standard deduction before the rates are applied, and a $110 personal exemption then comes off the tax itself rather than off income.
Delaware 2026 tax brackets

Assumptions
- Ordinary-income rate schedules only; no credits, AMT, capital-gains rates, QBI deduction or the 2025–2028 senior deduction.
- Standard deduction (plus additional amounts for 65+/blind) or your itemized figure, whichever is larger; no dependent-filer limitation.
- Married filing separately uses half the joint federal thresholds, per the IRS schedule, and the state's single-filer schedule.
- State tax uses each state's published rate schedule, standard deduction and personal exemption for the tax year shown with the results; the source URL and year for the state you pick are printed above the results, along with the simplifications made for that state.
- State figures exclude county, municipal and city income taxes, itemized deductions, retirement and capital-gains exclusions, and credits that phase out. Unlisted states fall back to the flat rate you enter.
