Membership lasts until a state withdraws or is expelled; either takes effect only at the start of a calendar quarter and only after sixty days' notice or more. A withdrawing state notifies the Governing Board and the chief executive of each member state's tax agency, gives public notice and posts its notice of intent on its website; it remains liable for its share, agreed in good faith with the Board on the basis of benefits and burdens, of financial or contractual obligations incurred before the withdrawal or expulsion takes effect. The Agreement remains valid among the other states.
