Company Member Benefits

Membership in COST is exclusive - only multistate companies that are not engaged in the business of tax advising or consulting may apply. When your company joins COST, every employee benefits – including employees outside of the tax department, such as government affairs and legal. That means multiple memberships for the price of one. COST offers many resources to help members make the most of their investment and connect with the benefits they value most. The annual dues allow your employees to:

participate in COST's renowned conferences and schools at significantly reduced prices;
access a national network of corporate state tax professionals (practitioners and industry members) sharing technical knowledge; and
help shape and benefit from COST's legislative, regulatory and judicial advocacy.
