Section 1446(f) Final Regulations: Key Changes to Guidance on Non-Publicly Traded Partnership Interest Transfers by Non-U.S. Persons
On October 7, 2020, the U.S. Internal Revenue Service (“IRS”) and Treasury Department released final regulations[1] providing guidance on the rules imposing withholding and reporting requirements under the Code[2] on dispositions of certain partnership interests by non-U.S. persons (the “Final Regulations”). The Final Regulations expand and modify proposed regulations[3] that were published on May 13, 2019 (the “Proposed Regulations”), and which we described in a prior Tax Talks post.[4] Unless otherwise specified, this post focuses on the differences between the Proposed Regulations and the Final Regulations affecting transfers of interests in non-publicly traded partnerships.
Enacted as part of the “Tax Cuts and Jobs Act,” Section 1446(f) generally requires a transferee, in connection with the disposition of a partnership interest by a non-U.S. person, to withhold and remit ten percent of the “amount realized” by the transferor, if any portion of any gain realized by the transferor on the disposition would be treated under Section 864(c)(8) as effectively connected with the conduct of a trade or business in the United States (“Section 1446(f) Withholding”).[5]
Prior to issuing the Proposed Regulations, the IRS had issued Notice 2018-08 and Notice 2018-29 to provide interim guidance with respect to Section 1446(f) Withholding.
