Federal Tax Status

Neither W&M nor VIMS is a 501(c)(3) organization. They are classified as exempt organizations due to our relationship with the Commonwealth of Virginia as a State Agency. Therefore, neither W&M nor VIMS has an IRS determination letter as requested by many granting agencies. However, if a granting agency can only give to a 501(c)(3) organization, please contact the Office of University Advancement, who can provide further information about related 501(c)(3) foundations that support the missions of W&M and VIMS.
