  • Excise Taxes
  • Realestate Property Taxes
  • Personal Property Taxes

These professionals have come together from backgrounds that include practice leadership from the world’s largest accounting and law firms, corporate management from “Fortune 500” companies, and executive positions with various state taxing agencies.

ISA provides a network that enables its members to stay informed of state and local tax issues across geographic, industry and tax specialty lines. Further, the firms and individuals that make up ISA are able to draw on the relationships and skill sets of their fellow ISA members when presented with the opportunity to introduce services or address issues and opportunities outside of the member’s own practice portfolio.

The foundation of the ISA is based on this spirit of knowledge sharing and peer support. While the members vary in practice size and specialty, one trait is common to each…the desire to consistently provide cutting-edge state and local tax services of the highest professional caliber and to associate with like-minded individuals and firms.
