Buying a Delaware Beach Home Now to Retire Here Later

Part of our Delaware Retirement and Second Home Guides.

By Bill Davis, Broker and Owner, Active Adults Realty, Lewes, Delaware. Published September 29, 2026. Every rule and figure on this page was checked against the Delaware Code, the Delaware Division of Revenue and the Delaware Department of Finance on September 29, 2026.

It is one of the most common plans we see: buy the beach house while you are still working, use it on weekends and vacations, and make it home when you retire. It works well in Delaware. The things to understand are when the state starts treating you as a resident, what you gain when you do, and the clocks that do not start until you move.

These are statewide rules. The income tax rules and the senior school tax credit below are Delaware law, and they are the same whether the home is in New Castle, Kent or Sussex County. What differs by county is the property tax itself, which each county and school district sets.

Are you a Delaware resident while it is a second home?

Owning a home here does not by itself make you a Delaware resident for income tax. Delaware counts you as a resident if Delaware is your domicile, meaning the place you intend as your permanent home, or if you keep a place to live here and spend more than 183 days of the year in the state. A second-home owner who stays 183 days or fewer and keeps their permanent home elsewhere is generally a nonresident.

That 183-day line matters to people who spend long summers and shoulder seasons at the beach. Keep track of your days.

While it is a second home you pay county and school property tax like any owner, and you do not get the senior school tax credit. For a beach home in Sussex County, see what a second home in coastal Delaware costs to own. If you rent it out, the state's 4.5 percent short-term rental tax and any town rental tax apply. See renting out a second home at the Delaware beaches.

What changes when you make Delaware home?

Once Delaware is your domicile, the state income tax rules that draw people here apply to you, in all three counties:

• Social Security is not taxed by Delaware.
• Up to $12,500 of pension and eligible retirement income is excluded for each person age 60 or older. Eligible retirement income includes interest, dividends, capital gains, net rental income from real property and distributions from plans such as IRAs and 401(k)s. The $12,500 is a combined limit per person.
• No sales tax. Delaware has no state or local sales tax, which matters more the more of your spending is local.

A 2026 change to watch. Senate Bill 219, signed August 17, 2026, was written to raise Delaware's military pension exclusion. As enacted, the pension exclusion section of the tax code now also sets a Delaware domicile period for filers age 60 or older: at least 3 years for anyone domiciled in Delaware before January 1, 2027, and at least 5 years for anyone domiciled on or after that date. How the Division of Revenue applies that to the general $12,500 exclusion is a question to put to your tax professional before you set a moving date. Our page on Delaware military pension and retirement taxes covers the bill.

Which clock starts when you move, not when you buy?

Delaware's Senior School Property Tax Credit takes 50 percent off your school property tax, up to $500 a year, for homeowners 65 and older on their primary residence. Anyone who made Delaware their legal home on or after January 1, 2018 must first have 10 consecutive years of Delaware domicile. As of September 29, 2026 that rule is still in force. A 2025 bill to shorten it, House Bill 72, has sat in committee since March 2025.

Here is the part the second-home plan changes: the 10 years count from when Delaware becomes your legal home, not from the day you bought the house. By the rule's wording, years spent as a part-time owner with your permanent home elsewhere do not count toward it. If you are weighing when to make the move official, that is a real number in the decision. Our page on the senior school property tax credit has the detail, and our guide to moving to Delaware covers the rest of the move.

How do you buy with the retirement in mind?

If the beach house will one day be the only house, buy the full-time home, not just the vacation home:

• First-floor living. A primary bedroom on the main level is easy to skip on a vacation house and hard to add later.
• The community's rules both ways. The rental rules that matter now and the occupancy rules that matter later. Some communities limit rentals, which matters while the home is still a second home.
• Year-round, not just summer. Visit in February. Check the drive to the doctors and the grocery store you would actually use. Our page on healthcare in Delaware for retirees has more.
• Flood and insurance costs you will carry for decades, not just one season.

If you still own a home elsewhere when the time comes, see buying in Delaware before you sell. This is the question we help people with more than any other: which community fits now and still fits in fifteen years.
