What Does COST Offer?

ADVOCACY

COST's advocacy program is oriented toward active involvement on state tax issues of broad importance to the membership.  COST advocates on behalf of its membership in the legislative, judicial and administrative arenas.  State and local government policymakers rely heavily on COST staff in formulating, implementing, and changing the state tax landscape.  COST's reputation as the nationwide voice of corporate taxpayers has garnered respect from the leadership of the National Conference of State Legislatures, the Federation of Tax Administrators, the National Governors Association, and even the Multistate Tax Commission.  COST's involvement in an issue on behalf of its corporate membership signals to state leaders that the issue is one of importance.  COST also serves as a resource on business tax issues to other organizations, including State Chambers of Commerce and state taxpayer associations, as those groups develop strategies to address complex state tax matters.

The COST team disseminates information on pertinent legislative, judicial and regulatory developments through regular publications, and coordinates advocacy activities with members and other sympathetic parties.  COST staff files amicus briefs with state and federal courts, provides testimony (oral and written) before legislative and administrative bodies, meets with state policymakers, and brings together interested members to enhance advocacy activities on targeted issues.

NETWORKING OPPORTUNITIES

One of the most often cited reasons for joining COST is the opportunity to network with other state tax professionals.  Experienced state tax professionals know very well that the answers to the many different state tax questions are often not accessible via research alone, but are based upon years of experience and discussions with peers.  COST promotes networking opportunities through its online member forum and at COST conferences, schools and regional meetings. COST members also participate in a number of issue specific task forces and committees, including FIN 48, property tax, unclaimed property tax, unclaimed property, sales & use tax, income/franchise tax and telecommunications taxes.

COST PUBLICATIONS

Since its inception COST has been a leading source for state tax information critical to its members. COST members use a variety of ways to stay connected to industry information, including publications, newsletters, exclusive website content, forums, special reports, and current development outlines. Members have access to up-to-date information when they need it.

"COST has been a tremendous resource for myself and my company.  In attending the COST meetings I return back to my company with various issues to research that could add value to my tax department.  I frequently use the COST member forum and the COST members as a resource for audit and controversy issues for insight I might not have considered.  This is a fantastic organization and I’m proud to belong to."
