Delaware vs federal income tax
On $75,000, federal income tax is $7,670 (10.2% of income) and Delaware takes $3,609 (4.8%). Delaware taxes income in 6 brackets from 2.2% to 6.6%. A single filer pays the top 6.6% rate on taxable income above $60,000. The first $2,000 of taxable income (single) is taxed at 0%.
Before the brackets apply, Delaware subtracts a standard deduction of $3,250 ($6,500 married filing jointly). It then takes a $110 credit ($220 married) off the tax itself.
Federal income tax comes off first. For 2026 the standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly, and the brackets run from 10% to 37%. Pre-tax 401(k) contributions (up to $24,500) lower your federal and most state income tax, but not FICA.
On a $75,000 salary, Delaware takes $3,909 a year in state taxes, which ranks #48 of 51 for take-home pay (Washington, D.C. included). The same earner in a state with no income tax, like Texas or Florida, keeps $61,593.

How is Delaware income tax calculated?
Before the brackets apply, Delaware subtracts a standard deduction of $3,250 ($6,500 married filing jointly). It then takes a $110 credit ($220 married) off the tax itself. What is left is your taxable income, and each slice of it is taxed at the rate for that bracket. Only the dollars above a threshold pay the higher rate.
What is the difference between my marginal and effective tax rate?
Your marginal rate is the rate on your next dollar of income: the top bracket you reach. Your effective rate is your total tax divided by your income. Because lower slices of income are taxed at lower rates, the effective rate is always lower. At $75,000 in Delaware, the combined marginal rate is 28.6% but the effective income tax rate is 15%.
