South Carolina Taxes for People Relocating to the Upstate
The honest reason a lot of our buyers move here is the after-tax math. South Carolina exempts Social Security, has no estate or inheritance tax, restructured its income tax in 2026 to a low two-bracket system, and assesses owner-occupied primary residences at a 4% ratio for property tax. For a couple relocating from New York, New Jersey, Massachusetts, Connecticut, Illinois, or California, the year-one tax savings often pay for the move and most of the closing costs.
This page walks through the SC tax picture the way we walk through it on a phone call with a relocation buyer. Nothing here is legal or tax advice — talk to a CPA before you close. But you'll understand what questions to ask.
State Income Tax (2026 and Forward)
South Carolina restructured its income tax in March 2026 with the passage of H.4216. The previous graduated brackets (which had already been compressed to a 6% top rate for tax year 2025) were replaced with a two-bracket system effective tax year 2026:
1.99% on the first $30,000 of taxable income.
5.21% on taxable income above $30,000 (with a $966 offset).
The law also decouples SC from federal standard/itemized deductions, uses Federal AGI as the starting point, creates a new SC Income Adjusted Deduction (SCIAD: $15,000 single / $22,500 head of household / $30,000 married filing jointly), and allows automatic future top-rate reductions if the Board of Economic Advisors projects revenue growth of 5% or more. Returns under the new structure are first due April 15, 2027.
This still isn't Florida (no income tax) or Tennessee (no income tax), but it's well below most northern states. A couple with $150,000 of taxable income pays roughly $7,000 in SC state tax under the 2026 structure — less than a quarter of what the same couple would pay in California or New York.
Social Security Is Fully Exempt
South Carolina does not tax Social Security benefits at the state level. Doesn't matter what your federal taxable percentage of SS is, doesn't matter your income level — SS is excluded from the SC return. Railroad retirement income is similarly excluded.
For a couple drawing combined Social Security of $60,000 a year, that's roughly $3,000 of state tax saved every year compared to the same couple in a state that taxes SS partially or fully.
The Retirement Deductions (Age 65 and Up)
South Carolina layers two deductions for older taxpayers:
Retirement-income deduction. Up to $10,000 of qualifying retirement income (pensions, IRA distributions, 401(k) withdrawals) for taxpayers age 65+.
Age 65 and older deduction. Separately, taxpayers 65+ may claim up to $15,000 deducted from any SC income.
Here's the catch: the Age 65 deduction is reduced by any retirement-income or military-retirement deduction claimed. For a married couple where both spouses are 65+, the combined caps still translate into a meaningful reduction before they ever hit the new lower brackets. The effective state tax rate on retirement income for many SC retirees ends up in the low single digits.
Property Tax — the 4% vs 6% Question
This is the section most relocation buyers miss until they get their first tax bill. South Carolina assesses property at one of two ratios:
4% — Owner-occupied legal residence. Your primary home if you actually live there, file your SC tax return from that address, and register your vehicles there.
6% — Second homes, rental property, investment property, raw land. Everything that isn't a legal residence.
The 50% difference in assessment ratio drives a meaningful tax bill difference. On a $500,000 home, the 4% ratio means roughly $1,500–$2,500 a year in property tax depending on millage rate; the 6% ratio means roughly $4,000–$6,500.
What qualifies for the 4% rate
To claim the 4% legal residence ratio you have to:
(1) Actually use the property as your principal residence; (2) File your SC state income tax return from that address; (3) Register all your vehicles at that address with the SCDMV; (4) Limit the property to no more than 5 contiguous acres for the 4% rate; (5) Not rent the property for more than 72 days per year.
The legal-residence application is filed with the county assessor (Greenville County, Spartanburg County, Cherokee County, etc.). It's a paper-shuffle, not a hard test — but if you don't file the application, the county defaults to the 6% rate.
What this means if you're keeping a property up north
You can only have one legal residence in SC. If you're snowbirding and keeping your house in New Jersey or New York, you have to decide which state is your domicile. If SC is your domicile, the SC house gets the 4% rate and the northern house becomes a second home up there. If your old state is your domicile, the SC house pays the 6% rate.
For most buyers the SC domicile is the right call because of the SS exemption, the lower income tax, and the lack of estate tax. But it's a decision worth running by a CPA before you change registrations.
Sales Tax
State sales tax is 6%. The combined rate varies by county:
Greenville County: 6% in most areas (no countywide local-option sales tax). Special districts can be higher.
Spartanburg County: 7% (6% state + 1% Capital Projects Tax).
Groceries are exempt from the state portion. Prescription drugs are exempt.
Vehicle Tax (IMF)
South Carolina charges an Infrastructure Maintenance Fee of 5% of the vehicle purchase price, capped at $500, at the time of titling and registration. Vehicles previously titled in another state pay a flat $250 when first brought to SC.
Separately, every car registered in SC pays an annual county vehicle property tax based on assessed value. For a typical late-model vehicle, the annual tax runs a few hundred dollars.
Estate Tax and Inheritance Tax
South Carolina has neither. SC has not had a state estate tax since 2005, and has never had an inheritance tax. Federal estate tax still applies above the federal exemption.
For relocation buyers coming from Massachusetts, New York, New Jersey, Connecticut, Illinois, Oregon, Washington, or any other state with an estate tax, this is a significant long-term planning factor.
Quick Tax Comparison for a Typical Relocation Buyer
For a retired couple, both age 67, drawing $60,000 of Social Security plus $90,000 of pension/IRA income, owning a $500,000 primary home in Greenville County:
South Carolina: SS not taxed. Retirement income absorbed largely by the 65+ deductions. Effective state income tax in the low single thousands. Property tax on the home roughly $1,500–$2,500 at the 4% ratio. No estate tax.
New York (Westchester): SS not taxed by NY, but pension/IRA may be subject to NY rates up to ~6.85%. Property tax on a comparable home easily $12,000–$20,000. Estate tax above $7M.
New Jersey: SS not taxed by NJ. Income tax up to 10.75% top bracket. Property tax on a comparable home often $10,000–$16,000. Estate tax repealed but inheritance tax remains.
California: SS not taxed by CA. Income tax up to 12.3% top bracket. Property tax capped at 1% by Prop 13 but on a much higher home value. No estate tax.
These are illustrative ranges — not your specific picture. Run real numbers with a CPA. But for most relocation buyers from high-tax states, the year-one state tax savings on moving to SC fall in the $8,000–$25,000 range.
Frequently Asked Questions
Does South Carolina tax Social Security?
No. Social Security is fully exempt from SC state income tax regardless of income level.
What is the current South Carolina income tax rate?
Effective tax year 2026, SC has a two-bracket structure: 1.99% on the first $30,000 of taxable income and 5.21% above (with a $966 offset). The structure was established by H.4216, signed in March 2026, and replaces the prior graduated brackets. Returns under the new structure are first due April 15, 2027. Future automatic reductions are tied to revenue growth.
What's the difference between the 4% and 6% property tax assessment ratios in SC?
4% applies to your owner-occupied legal residence; 6% applies to second homes, rentals, investment property, and land. Establishing the 4% rate requires filing the legal residence application with the county assessor and meeting the domicile tests (SC tax return, vehicle registration, principal-residence use).
What's the sales tax in Greenville and Spartanburg?
Greenville County: 6% in most areas (no countywide local-option sales tax). Spartanburg County: 7% (6% state + 1% Capital Projects Tax). Groceries and prescription drugs are exempt from the state portion.
Does South Carolina have an estate tax or inheritance tax?
No to both. SC has not had a state estate tax since 2005 and has never had an inheritance tax. Federal estate tax still applies above the federal exemption.
How much retirement income can someone 65+ deduct in South Carolina?
Up to $10,000 retirement-income deduction (pension, IRA, 401(k)) plus up to a $15,000 Age 65 deduction against any income (reduced by any retirement-income or military-retirement deduction already claimed).
If I keep my house up north and buy a second home in Upstate SC, what tax rate do I pay?
The SC property is assessed at the 6% non-owner-occupied ratio — roughly 50% higher property tax than the 4% legal-residence rate. You can only claim the 4% rate on one home and only if you establish SC as your legal domicile (SC tax return filed, vehicles registered in SC, principal-residence use).
