Act 110 (signed March 30, 2026) set two brackets for tax years after 2025: 1.99% on the first $30,000 of taxable income, 5.21% above that. Social Security income is fully exempt, and the age-65 and retirement-income deductions are coordinated (not additive), capped at $15,000 combined -- the same statewide mechanics documented in south-carolina.js and irmo-sc.js, restated here as place-level context.
A low statewide property tax rate applies here as elsewhere
South Carolina's statewide average effective property tax rate is roughly 0.51%, restated from south-carolina.js as place-level context -- a genuine, low-tax advantage for Chapin homeowners.
Sales tax carries a real, disclosed disagreement between sources
Avalara cited a 7.00% minimum combined sales tax rate (6% state + 1% special district), while SalesTaxHandbook cited 8.00% (6% state + 1% Lexington County + 1% special district) -- the variation likely reflects whether a special-district or county-wide component applies to a specific address. Confirm before budgeting.
No hurricane-specific insurance premium applies to this inland market
Chapin sits well inland with zero direct hurricane-landfall or storm-surge risk, so homeowners insurance here is not shaped by the coastal wind/hail-driven premiums documented for this dataset's coastal SC markets -- though the real, regional inland-flooding pattern (see the climate topic) still matters for flood-specific coverage near the lake or waterways.
Key takeaways
- South Carolina's Act 110 two-bracket income tax (1.99% under $30,000 taxable income, 5.21% above) applies statewide, with Social Security fully exempt and a coordinated, $15,000-capped age-65/retirement-income deduction.
- South Carolina's roughly 0.51% statewide average effective property tax rate is a genuine, low-tax advantage.
- Combined sales tax carries a real, disclosed spread (7.00%-8.00%) between Avalara and SalesTaxHandbook -- confirm the applicable rate for a specific address.
- Chapin's inland location means no coastal hurricane-driven insurance premium applies, though lake/waterway-adjacent flood coverage is still worth confirming specifically.
