For Montgomery County residents approaching retirement, Delaware is consistently floated as the tax-smart alternative just a couple of hours down I-95. The pitch is real — Delaware has genuine advantages. But so does staying in Maryland. Here’s the honest, numbers-based comparison.
Cost of Living: Delaware Wins
Delaware is meaningfully less expensive than Maryland across most categories. The median home price in Delaware runs approximately $290,000-$310,000 versus $340,000-$380,000 in Maryland, according toZillow’s state-level data. Groceries, utilities, and transportation also run roughly 8-12% lower in Delaware. For retirees on fixed incomes, these savings compound meaningfully over a 20-year retirement.
State Income Tax: Delaware Wins Significantly
Maryland’s state income tax runs 2-5.75% depending on income bracket, plus a Montgomery County income tax of 3.2% — so total state/local income tax for a Montgomery County retiree can reach nearly 9% on income above $250K.Maryland’s comptroller sitehas the full rate schedule.
Delaware’s top state income tax rate is 6.6%, with no local income tax — and critically, Delaware offers retirement-friendly exemptions: up to $12,500 of pension/retirement income is excluded from state tax for residents over 60, and Social Security isfully exempt.Delaware Division of Financeconfirms these exemptions.
Property Taxes: Delaware Wins Significantly
This is one of Delaware’s most significant advantages. Delaware’s effective property tax rate is approximately 0.57% of home value — among the lowest in the country. Montgomery County’s effective rate runs approximately 1.0-1.1%. On a $500K home, that’s $2,850/year in Delaware versus $5,000-$5,500/year in Maryland. Over 20 years, that’s a $43,000-$53,000 difference on property tax alone.
Sales Tax: Delaware Wins (No Sales Tax)
Delaware hasno state sales tax— one of only five states in the country. Maryland’s sales tax is 6%. For retirees who are spending down savings and making large purchases, this adds up.Sales Tax Institutetracks this by state.
Healthcare: Maryland Edges Ahead
Montgomery County has exceptional healthcare access — Suburban Hospital (Johns Hopkins affiliate), Shady Grove Medical Center (part of the University of Maryland Medical System), Holy Cross Hospital, and proximity to NIH Clinical Center. Delaware’s hospital infrastructure is concentrated in Wilmington and Dover, with thinner coverage in more rural and coastal areas.U.S. News state health rankingsconsistently place Maryland above Delaware on healthcare access.
Proximity to Family and DC: Maryland Wins
For retirees with family in the DC/Maryland area, staying in Montgomery County maintains proximity to children, grandchildren, and established social networks. Delaware’s coastal and suburban communities — Rehoboth Beach, Lewes, Wilmington suburbs — are 2-3 hours from Montgomery County. This is a lifestyle consideration that no tax calculation captures but that consistently emerges as the primary reason people stay in Maryland.
The Bottom Line
Delaware wins on pure financial metrics — lower taxes across virtually every category, lower cost of living, no sales tax. Maryland wins on healthcare access, proximity to DC, and staying close to established community. For retirees whose primary driver is financial efficiency and who don’t have deep DC-area family ties, Delaware is worth serious consideration. For those with family in the region or who value the Montgomery County lifestyle — the amenities, the schools for grandchildren, the cultural access — the tax premium may be worth paying.
