Establishes temporary sales tax exemption for small businesses impacted by ongoing public highway projects.

This bill would temporarily exempt small retail businesses in areas affected by highway construction from paying state sales tax during active projects. To qualify, businesses must have 50 or fewer full-time employees, be independently owned, and operate within an "impacted construction zone" where highway work blocks traffic or access. Businesses must apply to the state tax director for approval, which would issue a certificate specifying eligible locations and the exemption period matching the project's duration (from start to completion). The exemption applies only to sales at the business during the construction phase, not to other tax obligations.
