  • Delaware exempts Social Security and Railroad Retirement entirely, then gates everything else on turning 60 -- the exclusion jumps from $2,000 to $12,500 on that birthday.
  • The exclusion is per taxpayer, so a married couple both over 60 can reach $25,000, but neither spouse can use the other's unused room.
  • An early distribution (1099-R box 7 code 1, or one that drew a federal early-withdrawal penalty) is disqualified from the pension exclusion outright, which is the most common way a Delaware retiree loses it.
  • Military retirees under 60 get the full $12,500 rather than the $2,000 everyone else under 60 gets; at 60 and over there is no military-specific advantage left.

Local income tax applies in parts of Delaware

WILMINGTON IS THE ONLY DELAWARE MUNICIPALITY THAT LEVIES A PERSONAL INCOME TAX, and it is a real 1.25% on top of the state rate for anyone who lives OR works in the city. It is an EARNED INCOME tax: it reaches salaries, wages, commissions, bonuses, and net profits from a business or profession, and it does NOT reach interest, dividends, capital gains, pensions or Social Security -- so a Wilmington retiree living on investment and pension income pays none of it while a Wilmington wage-earner pays it on every dollar. It applies to non-residents who work in the city as well as to residents, with no exemption threshold and no standard deduction of its own. Employers withhold it. No other Delaware city, town or county levies an income tax; Delaware's other local revenue is property-tax based. The 1.25% rate has been stable for many years but is set by city ordinance rather than state statute, so it can change without a state-level signal.
