55+ Communities in Hilton Head / Beaufort

The Hilton Head and Beaufort area — South Carolina's Lowcountry — is where retirees come for coastal living without Florida's traffic, crowds, and insurance headaches. The region stretches from Hilton Head Island's 12 miles of Atlantic beaches and 24-plus championship golf courses, through the fast-growing Bluffton/Okatie corridor, to the antebellum streets of downtown Beaufort and the marshes of Port Royal. South Carolina's tax picture does a lot of the work for retirees here: Social Security is fully exempt, retirees 65+ pick up a $10,000 retirement-income deduction plus a broader $15,000 age-65 deduction, there's no estate or inheritance tax, and the state's average effective property tax rate is roughly 0.57% — with a $50,000 Homestead Exemption on top for owner-occupants 65 and older.

Cost of living varies sharply across this area. Hilton Head Island lands roughly 4.3% above the U.S. average and about 17% above the South Carolina average per BestPlaces, driven almost entirely by housing — Zillow puts island home values around $762,000 in 2026, up about 2% year-over-year. Bluffton runs similarly premium. Beaufort itself is materially cheaper: rentals average about $1,445/month (roughly 11% below the national average), and median list prices sit closer to $421,000 — about 15% below the U.S. average. Categorically across the area: housing is the swing factor (cheap in Beaufort, expensive on the island), utilities run slightly below to slightly above national average depending on source, groceries track close to national, and healthcare is roughly 2–5% below the national average.

Retiree Specific: South Carolina does not tax Social Security benefits at all. Residents 65 and older can deduct up to $10,000 of qualifying retirement income (pensions, IRAs, 401(k)s) and separately claim a broader $15,000 age-65 deduction against any South Carolina income — $30,000 for a couple where both spouses are 65+. Military retirement pay is fully exempt regardless of age. The state has no estate tax and no inheritance tax. Property taxes are among the lowest in the country: the statewide average effective rate is about 0.57%, and Beaufort County's median effective rate runs around 0.66–0.74% depending on ZIP. Owner-occupied primary residences are assessed at just 4% of fair market value (versus 6% for second homes and investment properties), and owners 65+ get the Homestead Exemption knocking the first $50,000 of fair market value off the tax rolls. State income tax is a flat 5% (down from 7%). Hilton Head Island sales tax is 7% combined.

Additional Considerations: The 4% primary-residence assessment ratio isn't automatic — you have to apply for it at the Beaufort County Auditor's Office, and the same is true of the Homestead Exemption. Non-owner-occupied and second-home buyers pay meaningfully more in property tax because of the 6% ratio, which matters if you're planning a snowbird arrangement before full-time residency. HOA, POA, and club fees in the resort communities and gated 55+ neighborhoods can add thousands to your annual cost — Hilton Head Plantation's POA is modest at around $1,400/year, but full club memberships at communities like Belfair, Colleton River, or Berkeley Hall run substantially higher. Wind and flood insurance are required near the coast and are a real line item — still generally cheaper than Florida, but not a rounding error. Finally, the 0.25% Real Estate Transfer Fee on Hilton Head Island funds the town's Land Acquisition Program and hits at closing.
