Overview 

The Residential Retrofit Credit is a nonrefundable income tax credit available to South Carolina homeowners who make eligible improvements to their legal residence to help mitigate damage from hurricanes, floods, and other catastrophic wind events. These retrofits are designed to strengthen the structure and improve resilience. 

Eligibility Requirements 

You may qualify for this credit if: 

• You own and reside in a single-family, owner-occupied residence located in South Carolina. 

• You made qualified retrofitting expenditures that improve the structural integrity of your home against wind damage or water intrusion. 

• The improvements were recommended by an insurer, licensed engineer, or contractor, and not required by law. 

• The work was completed by a licensed contractor (or yourself, if properly permitted and approved). 

Note: Qualifying improvements include roof bracing, secondary water barriers, impact-resistant windows/doors, and strengthening gable ends or load paths. 

Credit Amount and Limits 

• The credit equals 25% of the qualified retrofitting costs, 

• Maximum credit: $1,000 per tax year, 

• Any unused portion may be carried forward for 5 years. 

This credit is nonrefundable, meaning it can reduce your tax bill to $0 but does not result in a refund.
