Sales Tax Analysis
Understanding Sales Tax in Construction
Sales tax rules for contractors are notoriously complex and vary significantly by state. Most states fall into one of two categories for construction contracts:
Material Only (TX, NC, etc.)
Contractors pay sales tax on materials when they purchase them, but may not be required to charge tax on labor or the final contract.
Total Contract (NY, NJ, etc.)
Tax is applied to the entire project sum, including labor, unless a "Capital Improvement" exemption certificate is filed.
