OFM works in cooperation with the New York State Department of Taxation and Finance (DTF) to ensure that all foreign missions and their members that are authorized for tax exemption by the Department of State receive due tax exemption for purchases made in New York State. In order to do so, missions and their members are required to complete and submit to vendors throughout New York, in addition to their tax exemption card, form DTF-950 (“Certificate of Sales Tax Exemption for Diplomatic Missions & Personnel”)
