Connecticut requires any exemption to be pre-approved by the state; otherwise, sales tax must be paid and a refund requested. If you paid more than a nominal amount of sales tax in Connecticut, please contact DFA at to discuss applying for a refund. All refund applications must be reviewed and submitted by DFA.

Tax exemption in Michigan involves a number of individual documents. If you need an exemption for Michigan, please contact the Tax office.



As an out-of-state charitable organization, Cornell has been advised to provide its New York State tax exemption certificate, which documents that New York recognizes Cornell as an exempt organization. Ask the vendor whether they accept the New York certificate to grant exemption in Wisconsin. If we are paying directly with a Cornell check, this should be acceptable.
