Which State Wins — and For Whom

South Carolina wins on property tax

Horry County’s 3-layer exemption stack produces effective rates well below both NC and TN for qualifying 65+ buyers. If property tax minimization is the primary financial goal, Myrtle Beach wins. The trade-off: lower income tax protection than Tennessee (SC still has state income tax on IRA draws above its retirement deduction), and no beach access as immediate as Wilmington’s.

Tennessee wins on income tax

Zero income tax on all income. No exclusion threshold. No phase-out. For buyers drawing $100,000+ in IRA and pension income, Tennessee saves $4,500–$8,000/year in state income tax compared to North Carolina and more compared to South Carolina above the retirement deduction threshold. The trade-off: no beach, hotter summers.

North Carolina wins on the combination of beach + tax

Wilmington is the only market of the three where real Atlantic Ocean access is a weekly reality at reasonable 55+ community price points. The tax environment is not as favorable as Tennessee or South Carolina, but it is genuinely competitive — especially for buyers whose income is largely Social Security (exempt) and modest IRA draws. For the buyer who wants coastal living with reasonable tax costs and genuine small-city culture, Wilmington has no direct equivalent in our coverage.

Bottom line for buyers comparing all three

If beach access is non-negotiable: Wilmington or Myrtle Beach. Between the two, Wilmington has lower property tax than Horry County’s published rates but Horry County’s 65+ exemption stack often produces lower actual bills. If income tax elimination is the primary driver: Nashville. If lowest total annual housing cost is the goal: Myrtle Beach often wins on property tax; Nashville often wins on income tax. Wilmington sits in the middle — not the cheapest overall, but the only one with genuine city character and direct Atlantic access.
