Does Delaware tax Social Security?
Does not tax Social Security
No. Delaware does not tax Social Security, and it should not be included in your Delaware taxable income.
What the Delaware Division of Revenue says
We do not paraphrase the rule from memory. This is the state's own wording, copied from the page linked below it:
“Social Security and Railroad Retirement benefits are not taxable in Delaware and should not be included in taxable income.”
Federal tax is a separate question
Even though Delaware does not tax it, the IRS can still tax part of your Social Security on your federal return. Whether it does depends on your other income. Our taxable Social Security calculator follows the IRS worksheet line by line, and this guide explains the rule.
You can ask Social Security to withhold federal tax from each payment. Withholding for Delaware state tax, if you need it, is arranged with the state, not with Social Security. State rules change with new laws, so check with the Delaware Division of Revenue before you file.
