Moving to South Carolina: The Retirement Hotspot

South Carolina's top income tax rate falls to 3.99% in 2026, down from 6.0% as recently as late 2024, making it one of the fastest-declining income tax states in the country. For retirees shopping for a lower-tax address, that trajectory matters as much as the current number.

What SC's 2026 Tax Changes Mean for Retirees

South Carolina passed a phased income tax reduction plan, and 2026 marks a significant milestone in that schedule. The top marginal rate is 3.99% this year, applying to income above $17,500.

Below that threshold, the rate is lower still. For most retirees drawing modest distributions from IRAs or pensions, the effective rate often lands well under 3%.

The Senior Deductions Are Substantial

South Carolina gives retirees two layers of protection before the income tax rate even kicks in.

First, Social Security income is completely exempt from state income tax. South Carolina is one of roughly 40 states that don't touch Social Security benefits at all. See our full breakdown of states that don't tax Social Security to see where SC ranks.

Second, retirees under 65 can deduct $10,000 of retirement income per person. Retirees 65 and older get $15,000 per person. For a married couple both over 65, that's $30,000 of pension, IRA, or 401(k) income sheltered before a single dollar of state tax applies.

A couple with $80,000 in combined retirement income, all from pensions, would subtract $30,000 in deductions, leaving $50,000 taxable. At a blended effective rate around 3.5%, their state income tax bill is roughly $1,750. That number would be several times higher in states like Minnesota or Vermont.

Property Taxes, Sales Tax, and What People Miss

Property taxes in South Carolina are low by national standards. The statewide average effective rate sits around 0.57%, compared to a national average closer to 1.1%. South Carolina also caps the assessed value of a primary residence at 4% of fair market value for owner-occupants, which shields longtime residents from runaway reassessments.

The state sales tax is 6%, but counties add their own rates. In many coastal counties popular with retirees, the combined rate hits 8% or 9%. Groceries are taxed at the state level, which is a meaningful hit on fixed-income budgets. That's a real cost that the income tax savings don't fully erase.

South Carolina has no estate tax and no inheritance tax. Whatever you've built passes to your heirs without a state-level cut. For retirees with estates above the federal exemption, the absence of a state estate tax is worth real money. Read more in our guide to estate tax by state.

South Carolina vs. North Carolina for Retirees

This comparison comes up constantly, and the gap is closer than most people expect.

North Carolina's flat income tax rate is 4.25% in 2026, with a further reduction scheduled for future years. NC exempts the first $35,000 of retirement income for most retirees over 65, which is more generous on that single line item than SC's $15,000 per-person deduction for married filers.

But South Carolina's overall income tax rate is lower, its property taxes are lighter, and it has no estate tax, same as NC. The coastal markets in SC, particularly the Myrtle Beach and Hilton Head areas, run cheaper than comparable NC mountain or Raleigh-area markets for home prices.

Climate, geography, and lifestyle preferences will drive the final call for most people. On pure tax math, South Carolina holds a slight edge for high-income retirees with large pension distributions. For retirees relying heavily on Social Security and a modest pension, the two states are nearly even. See our full comparison in best states for retirees to avoid taxes.
