South Carolina Property Tax Law Changes 2026: What Homeowners Need to Know

Updated March 2026

Key Takeaway

South Carolina has the lowest residential assessment ratio in the nation: just 4% of market value. Combined with a 15% reassessment cap and a $50,000 homestead exemption for seniors 65+, this makes South Carolina one of the most tax-friendly states for homeowners. Reassessment only occurs at point of sale (Act 388, 2006).

4% Residential Assessment Ratio

South Carolina's 4% assessment ratio for owner-occupied primary residences is the lowest in the nation. A $200,000 home has an assessed value of just $8,000. Non-owner-occupied residential is assessed at 6%, and commercial at 10.5%. Make sure your property is correctly classified as owner-occupied to receive the 4% rate.

Act 388: Reassessment at Point of Sale

South Carolina's Act 388 (2006) fundamentally changed the property tax system:

Reassessment to market value occurs only when the property sells (not on a regular cycle for homesteads)
The 15% cap limits cumulative assessment increases within a reassessment cycle
School operating taxes on owner-occupied homes are eliminated (replaced by a 1-cent sales tax increase)

This means long-term homeowners can have very low assessed values while new buyers pay taxes on the full purchase price.

$50,000 Senior Homestead Exemption

South Carolina provides a $50,000 exemption from fair market value for homeowners 65+ and permanently disabled. At the 4% assessment ratio, this removes $2,000 from your assessed value. Combined with Act 388's elimination of school operating taxes, seniors in South Carolina can have extremely low property tax bills.

90-Day Appeal Window

You have 90 days from your assessment notice to file an appeal with the county Board of Assessment Appeals. Given that reassessment primarily occurs at point of sale, most appeals are filed by recent buyers who believe their purchase price-based assessment exceeds actual market value.
