Delaware Income Tax Calculator (2026 Filing Season)
Delaware 2025 brackets: 2.2%–6.6%, depending on income and filing status.
No state or local sales tax — Delaware leans on income and franchise taxes instead.
We subtract Delaware's standard deduction ($3,250) automatically.
The same $75,000 income in a no-income-tax state (Texas, Florida, Tennessee…) would owe $0 in state income tax — a difference of $3,719 per year.
We only store your state and filing status — never your income.
