Delaware is a popular state to retire in, and its income tax rules are a big reason why. Social Security is fully exempt, pensions and retirement-plan withdrawals get a generous exclusion, and there is no state estate or inheritance tax. This tool estimates the state income tax on your retirement income.
How it works
Each source is treated differently before Delaware’s rates apply:
Social Security → fully excluded (taxable = $0)
pension + IRA/401(k) → reduce by exclusion ($2,000 under 60, $12,500 at 60+)
taxable income = remaining pension/withdrawals after exclusion
delaware tax = graduated rates (2.2% to 6.6%) on taxable income
The 12,500 dollar exclusion is per taxpayer, so a married couple where both are 60 or older can exclude up to 25,000 dollars of eligible retirement income between them.
Example and tips
A 65-year-old with 24,000 dollars of Social Security, a 20,000 dollar pension, and 10,000 dollars of IRA withdrawals excludes all Social Security and 12,500 dollars of the 30,000 dollars in pension and IRA income, leaving 17,500 dollars taxable. Delaware tax on that is roughly 800 to 900 dollars. To stretch the benefit, married retirees should split eligible income so each spouse uses a full exclusion.
