For most people comparing NC vs SC taxes, the honest answer is that neither state is uniformly cheaper. North Carolina charges a flat 3.99% income tax for 2026 and has low, uncapped property assessments; South Carolina uses progressive brackets topping out around 6% but shelters retirement income, long-term capital gains, and owner-occupied homes far more aggressively. Who wins depends on your income level, your age, whether you own a home, and even what kind of car you drive.
Income Tax: Flat Rate vs Progressive Brackets
North Carolina taxes all individual income at a single flat rate of 3.99% for 2026.1North Carolina Department of Revenue. Tax Rate Schedules The standard deduction is $12,750 for single filers and $25,500 for married couples filing jointly, and there is no personal exemption.2North Carolina Department of Revenue. 2026 Income Tax Withholding Tables and Instructions for Employers Once you know your taxable income, one multiplication gives you your tax bill.
South Carolina uses tiered rates from 0% up to a top marginal rate of 6% for the 2025 tax year, with further reductions possible.3South Carolina Department of Revenue. Individual Income Tax The brackets are narrow. For 2024, income up to $3,460 was taxed at 0%, income from $3,460 to $17,330 at 3%, and everything above $17,330 at the top rate.4South Carolina Department of Revenue. 2024 South Carolina Individual Income Tax Tables The state starts from your federal taxable income, so the federal standard deduction already reduces your SC tax base, and a $4,930 dependent exemption applies per qualifying child or relative for 2025.
The practical result: a single person earning around $50,000 roughly breaks even or slightly favors South Carolina after deductions and the 0% bracket. Past $75,000, North Carolina’s flat rate pulls ahead, and the gap widens as income climbs. A household with $200,000 in taxable income saves noticeably in North Carolina. Retirees, though, need to keep reading, because South Carolina’s retirement-specific deductions rewrite the math.
Retirement Income
Both states fully exempt Social Security benefits from state income tax.5North Carolina Department of Revenue. Social Security and Railroad Retirement Benefits6South Carolina Department of Revenue. Retirees – Lower Your Individual Income Tax Bill With These Five Tips Everything else about retirement income is where the two states part ways.
Pensions, 401(k)s, and IRAs
North Carolina taxes private pensions, 401(k) distributions, and IRA withdrawals at the flat 3.99% rate with no general retirement deduction. One important carve-out exists under the Bailey Settlement: if you retired from a North Carolina state or local government plan, or from a federal plan including military, and had five or more years of creditable service as of August 12, 1989, your retirement benefits are fully exempt from NC income tax.7North Carolina Department of Revenue. Bailey Decision Concerning Federal, State and Local Retirement Benefits The Bailey exemption covers the NC Teachers’ and State Employees’ Retirement System, the Local Governmental Employees’ Retirement System, the Federal Employees’ Retirement System, and the U.S. Civil Service Retirement System, among others. It does not apply to retirees from other states’ government plans.
South Carolina is broadly more generous. Taxpayers under 65 can deduct up to $3,000 per year of qualified retirement income from pensions, 401(k)s, and IRAs. At 65, that deduction rises to $10,000. A separate $15,000 age-65 deduction applies against any state income, reduced dollar-for-dollar by whatever retirement income deduction you already claimed.8South Carolina Department of Revenue. SC Revenue Ruling 21-13 – Age 65 and Older Deduction, Retirement Deductions, and Earned Income Offset A 65-year-old single filer can effectively shelter up to $15,000 of combined income.
Military Retirement
Military retirement pay is fully exempt from South Carolina state income tax, regardless of age or other income.9SC Department Of Veterans’ Affairs. Claiming Military Retiree State Income Tax Exemption in SC North Carolina has no comparable blanket exemption; military retirees only escape NC tax if they qualify under the Bailey Settlement’s August 1989 service requirement. For anyone drawing military retirement, this is a substantial swing toward South Carolina.
Capital Gains and Dividends
North Carolina taxes short-term gains, long-term gains, and dividends at the same flat 3.99% as ordinary income. South Carolina lets you deduct 44% of net long-term capital gains from state taxable income.10South Carolina Legislature. South Carolina Code 12-6-1150 – Net Capital Gain Deduction From Taxable Income for Individuals, Estates, and Trusts That cuts the effective state rate on qualifying gains from roughly 6% down to about 3.4%. For someone selling a business, appreciated stock, or investment real estate, South Carolina’s long-term gains treatment is one of its strongest advantages.
Property Taxes
Property tax is where the two states diverge most, and for homeowners it often outweighs everything else combined.
Assessment Ratios
North Carolina assesses real property at 100% of appraised fair market value, with mandatory reappraisal at least every eight years.11North Carolina General Assembly. North Carolina General Statutes 105-286 The county millage rate applies to the full appraised value, and average effective rates generally fall between 0.60% and 0.82%.
South Carolina uses a classified assessment ratio. An owner-occupied primary residence is assessed at just 4% of fair market value; second homes, rentals, commercial property, and vacant land are assessed at 6%.12South Carolina Department of Revenue. Individual Property Tax – Chapter 5 On a $350,000 primary home, the millage applies to just $14,000 of assessed value, not the full market price. Average effective rates for SC homeowners land around 0.50%.
The 15% Reassessment Cap
South Carolina counties reassess on a five-year cycle, and any increase in a parcel’s fair market value is capped at 15% over that five-year period.12South Carolina Department of Revenue. Individual Property Tax – Chapter 5 If a home’s market value jumped 40% during the cycle, the assessed value can only increase 15%. The cap resets when the property changes hands, and it doesn’t apply to new construction or major improvements.
North Carolina has no statewide reassessment cap. When a county reappraises and your home’s value has surged, the full increase hits your tax base right away. In fast-appreciating markets around Charlotte and Raleigh, that produces significant year-over-year jumps in property tax bills.
Homestead Exemptions
North Carolina offers a homestead exclusion for homeowners at least 65 or totally and permanently disabled, provided income does not exceed $38,800 for the 2026 tax year. The exclusion shields the greater of $25,000 or 50% of the home’s appraised value.13North Carolina Department of Revenue. 2026 Application for Property Tax Relief
South Carolina exempts the first $50,000 of fair market value from all property taxes for homeowners 65 or older, legally blind, or totally and permanently disabled.14South Carolina Department of Revenue. Local Government Services – Homestead Exemption Because it sits on top of the 4% assessment ratio, it can wipe out most of the tax bill for qualifying residents on a moderately priced home.
Sales Tax
North Carolina’s statewide base sales tax rate is 4.75%, with counties adding 2% to 2.75%, bringing combined rates to between 6.75% and 7.50%.15North Carolina Department of Revenue. Sales and Use Tax Rates16North Carolina Department of Revenue. Current Sales and Use Tax Rates Most unprepared groceries are exempt from the state rate, though local taxes of up to 2% can still apply.
South Carolina starts higher with a 6% statewide base rate.17South Carolina Department of Revenue. Sales Tax Voter-approved local option taxes can push combined rates up to 9% in some counties. Prescription drugs are exempt, but most groceries are taxed at the full rate. On everyday non-food purchases the two states land in a similar range; at the grocery store, North Carolina’s exemption gives its residents a real recurring edge.
Vehicle Taxes and Registration
This category catches nearly everyone off guard when they cross the border.
Buying
North Carolina charges a one-time 3% Highway Use Tax on every vehicle title transfer, paid in place of sales tax. For most passenger cars and trucks there is no cap, so a $40,000 vehicle costs $1,200 in HUT and a $60,000 vehicle costs $1,800. A $2,000 maximum applies only to Class A and Class B motor vehicles (heavy commercial) and recreational vehicles.18North Carolina General Assembly. North Carolina General Statutes 105-187.3 – Rate of Tax
South Carolina caps sales tax on a vehicle purchase at $500, at a max-tax rate of 5%, regardless of the vehicle’s price.19South Carolina Department of Revenue. Maximum Tax (Max Tax) A $10,000 car and a $90,000 truck both trigger the same $500. On expensive vehicles, that saves thousands compared to North Carolina.
Owning
The savings reverse after the sale. North Carolina charges a modest annual registration fee — $46.25 for a standard passenger vehicle — plus $66.75 for the initial title. Electric vehicles pay $214.50 annually and hybrids $107.25 to offset unpaid gas taxes.20North Carolina Department of Transportation DMV. Fee Schedule (MVR-94)
South Carolina imposes an annual personal property tax on vehicles, and it must be paid before you can renew registration. The tax is calculated on 6% of the vehicle’s depreciated fair market value multiplied by the county millage.12South Carolina Department of Revenue. Individual Property Tax – Chapter 5 On a newer $30,000 vehicle, the annual tax easily runs $300 to $500 depending on the county, decreasing as the vehicle depreciates. The biennial registration fee is $40 for most passenger cars, and the title fee is $15.21South Carolina DMV. Fees You save at the point of sale in South Carolina, but you pay every year thereafter. Over a typical ownership period, the annual property tax often exceeds what North Carolina collected up front, especially on newer or more expensive vehicles.
Business Taxes
North Carolina’s corporate income tax dropped to 2% for 2026 and is on a legislated path to 0% by 2030. The state does impose a franchise tax on corporations at $1.50 per $1,000 of tax base, with a $200 minimum and a $500 cap on the first $1,000,000 of tax base.22North Carolina Department of Revenue. Corporate Income and Franchise Tax Rates
South Carolina charges a flat 5% corporate income tax with no announced phase-down.23South Carolina Department of Commerce. Corporate Income Tax and Incentives There is no separate franchise tax. For pass-through entities like S-corps and LLCs, income flows through to the owners’ individual returns, so the individual income tax comparison is what matters.
Working Across the Border or Moving Between States
The Charlotte metro area alone puts hundreds of thousands of workers within commuting distance of both states, and residents move between them constantly.
Living in One State, Working in the Other
North Carolina and South Carolina do not have a reciprocal tax agreement. If you live in one state and earn wages in the other, you generally owe tax to the state where the work is performed and then claim a credit on your home state return to avoid double taxation. Both states allow this credit.24South Carolina Legislature. South Carolina Code 12-6-3400 – Credit for Income Tax Paid by South Carolina Resident to Another State The credit equals the lesser of the tax actually paid to the other state or the proportional tax your home state would have charged on the same income. You file a nonresident return in the work state and a resident return in the home state, attaching the nonresident return when claiming the credit.
Moving Mid-Year
Relocate from one Carolina to the other during the tax year and both states treat you as a part-year resident. North Carolina taxes all income earned while you were a resident, plus any NC-source income (wages from a job still located there, income from NC rental property) earned after you left.25North Carolina Department of Revenue. Individual Income Filing Requirements File Form D-400 with Schedule PN to calculate the NC-taxable percentage.
Establishing South Carolina Residency
South Carolina uses domicile, not a day-count rule, to determine residency. The state does not apply a 183-day threshold.26South Carolina Department of Revenue. A Guide to Determining a Taxpayers Domicile for Income Tax Purposes The Department of Revenue weighs where you registered your car and got your driver’s license, where you’re registered to vote, where your spouse and family live, and where your professional and social ties sit. Moving your driver’s license, vehicle registration, and voter registration promptly all help establish domicile. Applying for the 4% owner-occupied assessment ratio on your SC home is another strong indicator.
Estate and Inheritance Taxes
Neither North Carolina nor South Carolina imposes a state-level estate tax or inheritance tax. Assets transfer at death without state tax consequence in either state; only the federal estate tax applies, and it reaches only estates exceeding the federal exemption, which most households never approach. For estate planning purposes, the two states are on equal footing.
