South Carolina enters this dataset as the Census Bureau's fastest-growing state in the country: Vintage 2025 estimates put its population at 5,570,274 as of July 1, 2025, up 1.5% year-over-year, with growth driven overwhelmingly by net domestic in-migration (66,622 people) rather than births or international arrivals. That growth story is corroborated, with a real nuance worth stating precisely, by moveBuddha's 2025-2026 migration report: South Carolina led all states in 2025's inbound-vs-outbound search ratio (driven heavily by Myrtle Beach, the single highest-inbound-share city in the country per that report), but the same report's forward-looking 2026 forecast section currently ranks South Carolina second among states for net inbound search share, behind Florida, North Carolina, and Texas -- both figures are real and worth knowing, and neither alone tells the whole story. The tax picture changed materially and very recently: Act 110, signed March 30, 2026, replaced the old three-bracket 0%/3%/6% income tax with two brackets (1.99% on the first $30,000 of taxable income, 5.21% above) for tax years beginning after 2025, with a statutory mechanism set to ratchet the top rate down further starting in 2027 if revenue growth targets are met. Social Security is fully exempt from South Carolina income tax at any age, and residents 65+ get real additional relief -- but the state's $15,000 age-65 deduction and $10,000 retirement-income deduction are coordinated, not additive, capping the combined benefit at $15,000 rather than $25,000, a distinction some retirement-planning sources blur. Property tax is a genuine, low-uncertainty positive (~0.51% statewide effective rate), while sales tax varies meaningfully by county, reaching a combined 9.00% in Charleston, Myrtle Beach, Hilton Head, and the Columbia area against a 6.00% state base and roughly 7.49% statewide average. Geographically, South Carolina has a real coastal-vs-inland hazard split worth stating explicitly rather than folding into one hurricane-risk label: the coast carries direct hurricane wind and surge exposure, anchored by Hurricane Hugo's catastrophic 1989 Category 4 landfall at Sullivan's Island (the last major hurricane to strike the SC coast directly) and Hurricane Matthew's 2016 coastal damage; the inland Pee Dee region has separately suffered record river flooding from storms that made landfall elsewhere, as Hurricane Florence demonstrated in 2018 with a state-record 23.63 inches of rain at Loris; and even the Upstate, genuinely a different four-season climate at the foot of the Blue Ridge with essentially no direct hurricane risk, saw 49 deaths and $370 million+ in damage from Hurricane Helene's remnant winds and flooding in September 2024. Economically, South Carolina's manufacturing base is real and export-oriented -- BMW's Spartanburg-area plant is the company's highest-volume plant worldwide and the state's largest industrial employer (~11,000 jobs), Boeing's North Charleston 787 Dreamliner line is its second-largest US manufacturing site, and the state exported $38.5 billion in goods in 2025, much of it through the Port of Charleston -- against a June 2026 unemployment rate (4.4%) that sits roughly in line with, not clearly below, the national rate, a more mixed labor-market signal than some other states in this dataset. Politically, South Carolina has voted Republican in every presidential election since 1980, with the margin widening in the most recent cycle (Trump +17.9 in 2024, up from +11.7 in 2020), alongside a Republican governor (term-limited, leaving office January 2027) and a veto-proof Republican supermajority in both legislative chambers.

The tradeoffs

Pros

The nation's fastest-growing state in the most recent full-year Census data (+1.5% in 2025, driven by net domestic in-migration), with genuine momentum corroborated by moveBuddha's independent search-based migration data, not just Census estimates; a low, well-corroborated ~0.51% statewide effective property tax rate; a newly simplified two-bracket income tax (1.99%/5.21%) with a statutory mechanism aimed at further reductions starting 2027, full Social Security exemption at any age, and real (if capped, not additive) retirement-income relief for residents 65+; a diversified, export-oriented manufacturing economy anchored by BMW's highest-volume global plant, Boeing's second-largest US assembly site, Michelin, and Volvo, moving $38.5 billion in exports through the Port of Charleston in 2025; and genuine regional variety within one state -- Lowcountry coast, Midlands, and Blue Ridge-foothills Upstate each offering a real, distinct climate and lifestyle choice rather than one statewide default.

Cons

Homeowners insurance carries real, well-documented regional risk that a single statewide average understates -- coastal counties (Charleston, Myrtle Beach, Hilton Head/Beaufort) face direct hurricane wind and surge exposure serviced partly through the state's residual-market Wind Pool, illustrated historically by Hurricane Hugo's catastrophic 1989 landfall and Hurricane Matthew's 2016 damage, while statewide averages already run South Carolina as high as the 16th most expensive state in the country per one 2026 source; the inland Pee Dee region has separately suffered record river flooding from slow-moving storms (Hurricane Florence, 2018), and even the hurricane-risk-free Upstate saw 49 deaths and $370 million+ in damage from Hurricane Helene's remnant winds and flooding in 2024 -- a genuinely underappreciated risk for a region marketed on its distance from the coast; the 65+ retirement-income tax relief is real but capped at $15,000 combined, not the $25,000 some sources imply by describing the two deductions separately; sales tax reaches a combined 9.00% in the state's largest visitor and metro markets; the June 2026 unemployment rate (4.4%) runs roughly in line with the national rate rather than clearly below it, a softer labor-market signal than Colorado's or Tennessee's in this dataset; and the state's rapid in-migration, while real by Census measures, is running second (not first) in moveBuddha's own forward-looking 2026 search-share forecast, behind Florida, North Carolina, and Texas -- worth knowing precisely rather than assuming an unqualified #1 ranking across every available migration metric.

Taxes

South Carolina's top state income tax rate is 5.21% (S.C. Governor Henry McMaster, "Governor McMaster Ceremonially Signs Income Tax Bill Into Law"; South Carolina Dept. of Revenue, "Information about H. 4216"; PolicyEngine, "South Carolina 2026 Tax Changes Calculator -- H.4216 / Act 110"). The statewide average effective property tax rate is 0.51%, though this varies significantly by county -- from 0.36% to 0.71%. A reliable statewide median annual property tax bill is not yet sourced.

Insurance

As with every state in this dataset, a single statewide homeowners insurance figure understates real regional variation -- South Carolina's coastal, inland/Pee Dee, and Upstate risk profiles are genuinely different perils (hurricane wind/surge; slow-moving-storm river flooding; remnant-system wind and flash flooding at elevation), not degrees of the same risk. Sources disagreed meaningfully on a single statewide average, from roughly $2,000/yr to roughly $3,100/yr depending on methodology and coverage assumptions -- MoneyGeek's figure (the higher end) placed South Carolina as the 16th most expensive state in the country for homeowners insurance in 2026. Coastal-market premiums specifically run well above even the higher statewide figure -- see regionalNotes.coastalHurricaneZone.
