Retire in the Carolinas. Only one state’s math actually works for your pension

How Each State Treats a Retirement Paycheck

Both states fully exempt Social Security from state income tax, so the 2027 cost-of-living adjustment tracking toward 3.1% lands in a retiree’s pocket the same way in Raleigh as it does in Greenville. The divergence starts with everything else.

North Carolina runs a flat individual income tax on pension distributions, IRA withdrawals, and 401(k) draws. South Carolina uses a graduated structure with a top bracket in the low 6% range, plus a retirement income deduction (larger once you turn 65) and an additional age-65 general deduction that pulls a meaningful slice of pension and IRA income out of the base. For a retiree living mostly on Social Security plus a modest pension, South Carolina often costs less. For a retiree pulling six figures a year from tax-deferred accounts, North Carolina’s flat rate tends to win once the SC deductions are exhausted.

The Tax Foundation’s 2025 State Tax Competitiveness Index ranks North Carolina 12th overall and South Carolina 33rd, driven mostly by South Carolina’s higher property tax rank. Adjusted state and local tax collections per capita come in at $6,021 for North Carolina and $6,167 for South Carolina, close enough that the pension mix, not the state line, decides the winner.

Property Taxes, Groceries, and the Coastal Insurance Problem

South Carolina’s property tax on an owner-occupied primary residence is unusually low because of the 4% assessment ratio for legal residents, and the Homestead Exemption knocks the first $50,000 of fair market value off the taxable base for residents 65 and older. North Carolina taxes primary residences at full assessed value with a more modest elderly and disabled exclusion that comes with income limits. On a paid-off $400,000 home, a South Carolina retiree with the homestead exemption typically pays less property tax than a North Carolina retiree in a comparable house.

Groceries are exempt from state sales tax in both states, and the combined state and local sales tax rates are similar.

The coast is where the cost picture diverges most. Homeowners insurance in barrier-island and beachfront counties (Brunswick, New Hanover, Carteret in North Carolina; Horry, Georgetown, Charleston, Beaufort in South Carolina) costs multiples of the same coverage inland, with separate wind and hail deductibles that can reach five figures per event. A retiree in Asheville, the Triangle, Greenville-Spartanburg, or Columbia faces materially lower homeowners insurance costs than a retiree in Myrtle Beach. Over a 25-year retirement, that gap compounds into real money.

Healthcare, Housing, and What the Budget Actually Looks Like

The 2026 standard Medicare Part B premium is $202.90 with a $283 annual deductible, and the Part A inpatient hospital deductible is $1,736. Those numbers are portable, but the surcharges tied to income from two years ago are not, and they can add thousands a year on top of the sticker premium (we mapped IRMAA and the other Medicare traps in a free guide here). Access to care also varies by geography. North Carolina concentrates four academic medical systems (Duke, UNC, Wake Forest, Atrium) within a two-hour radius of most of the state. South Carolina’s tertiary care is anchored by MUSC in Charleston and Prisma in the Upstate, with longer drives from the Grand Strand and the Lowcountry interior.

On cost of living, the BEA puts North Carolina’s regional price parity at 94.326 and South Carolina’s at 93.749, both under the national 100 baseline. Purchasing-power-adjusted real income runs $69,544 in North Carolina versus $64,693 in South Carolina. Housing is expensive everywhere right now: the Case-Shiller National Index sits at 336.7 as of June 2026, and existing home sales fell to 4.06 million annualized in July 2026, a soft resale market that gives buyers modest leverage in both states.

Where North Carolina Fits, and Who Is Better Served by South Carolina

North Carolina works well for most retirees. The flat income tax is predictable, the academic medical density is a real advantage, and inland metros like the Triangle, the Triad, and Asheville offer a lifestyle where insurance premiums stay manageable within a typical withdrawal plan. Run the numbers on a portfolio built to cover roughly the $78,535 average annual household expenditure from the 2024 BLS survey, after subtracting Social Security, and using a 4% withdrawal rate on the gap. North Carolina leaves you more room for the healthcare surprises that tend to define late retirement.

South Carolina wins for a specific type of retiree. Someone who relies mostly on Social Security plus a moderate pension, has a paid-off house, is planted inland in places like Greenville, Columbia, or Aiken where the homestead exemption and 4% assessment ratio do their heaviest work, and does not have to worry about coastal insurance costs. For that retiree, South Carolina’s tax and property structure tends to produce lower annual costs. Outside of that profile, North Carolina’s flat tax and healthcare access tend to carry more weight.
