2026 Spring Conference / Audit Session

This Conference will feature presentations on the most recent income and sales tax developments, initiatives, and case law updates, and include breakout sessions that will provide in-depth discussions of specific topics for maximum coverage of the hottest income and sales tax issues. Several state income and sales tax audit sessions (for industry members-only) will also be featured, offering a state-by-state exchange of information on legislative, audit, judicial, and regulatory issues affecting COST-member companies.

The goal of this program is to bring multistate tax professionals, with various levels of experience in state and local income/franchise taxes and sales/use taxes, together in an environment that allows for extensive interaction and exchange of information. Additionally, the conference will provide updates on key SALT issues and insights regarding state tax trends and opportunities. The program is targeted to all levels of experience, and no advance preparation is needed. 

This Conference/Session is open to COST Industry Members, non-COST Industry members and Practitioners.
