Connecticut is consistently ranked among the worst states for retirement taxes: income tax on Social Security above $75K income, estate tax starting at $2M, sales tax at 6.35%, and Fairfield County property taxes running 1.75%+. Delaware eliminates or dramatically reduces every one of these. Here is the specific math for CT buyers.

Buyers from Greenwich, Westport, Darien, or New Canaan carry significant home equity from CT real estate. Four Seasons at The Estuary ($480K), Coastal Club ($500K+), or Bayside ($400K–$700K) in Sussex coastal Delaware absorb Fairfield County equity and deliver resort-level amenities at a fraction of Fairfield County’s carrying costs. The property tax comparison is particularly stark: a $500K Delaware home at 0.47% costs $2,350/yr in taxes. A $500K Fairfield County home costs $8,750/yr.
Noble’s Pond in Dover ($300K–$400K) or Village of Eastridge in Smyrna ($340K–$450K) serve buyers with more modest budgets who want a significant retirement tax improvement without a premium coastal price tag. Property taxes under $1,900/yr, Social Security fully exempt, zero sales tax.
Buyers leaving Old Lyme, Madison, or Guilford who want continued beach adjacency will find the Sussex coastal communities (Lewes, Rehoboth corridor) most analogous. The Delaware beaches are a different character than the Long Island Sound shoreline — more Atlantic Ocean energy, less protected cove character — but the proximity lifestyle (12–15 minutes from Lewes) replicates the shoreline feel.

Connecticut has an estate tax starting at $2 million at rates of 12–16%. Delaware has no estate tax and no inheritance tax. For couples with combined estate values approaching $2M+ — a realistic threshold for anyone who owned Connecticut real estate for two decades — the estate tax differential is a planning-level consideration, not just an annual savings calculation. Delaware domicile eliminates Connecticut estate tax exposure entirely. Consult an estate planning attorney to model the specific impact for your situation.
The estate tax question alone can justify getting Delaware domicile advice. We can connect you with a Delaware specialist.
