Form 990
Form 990 is an annual reporting return that United States federally tax-exempt organizations must file with the United States Internal Revenue Service. It provides information on the filing organization’s mission, programs, and finances to ensure transparency and public interest of tax-exempt organization. Because the the IETF Administration LLC is covered by the Internet Society's 501(c)(3) registration, it is included in the ISOC Forms 990, which are reposted here. More information is available on the ISOC website.

Meeting Statements
Please note that it takes several months for all meeting-related expenses to be reconciled, so statements will not be posted immediately after the meeting occurred. Note: For IETF 107 through IETF 112, no meeting statements are available as these were fully online/virtual meetings. For IETF 113 and onwards, these are taking much longer to produce than expected due to issues with VAT reclaims.
