Part VII – Partner Closing Agreements Under Applicable Regulations

Publication 5346 — Instructions for Form 8980, Partnership Request for Modification of Imputed Underpayments Under IRC Section 6225(c) · 2026-10-03 edition · updated 2026-10-04 · United States

Under applicable regulations, a partnership may request modification based on partnership adjustments that were included in a closing agreement pursuant to section 7121 entered into by the IRS and the partnership or any relevant partner, or both if appropriate. Any partnership adjustment that is taken into account under such closing agreement and for which any required payment under the closing agreement is made, will not be taken into account in determining the imputed underpayment. Generally, if the IRS approves a modification based on a relevant partner’s closing agreement under this section, additional modifications with respect to that partner will not be approved.

Caution: Closing agreement modification is not permitted for an AAR.

Note: Use Part VII only for partner closing agreements . If the source partnership (rather than the partners, individually) entered into a closing agreement, do not use Part VII. Instead, use Part IX, Other Modifications, to request modification based on the source partnership closing agreement.

Example 1 : A partnership originally reported U.S. source dividends as a Return of Capital (ROC). ROC is not subject to Chapter 3 withholding. Upon exam, the IRS determined that the U.S. source dividends were incorrectly characterized as ROC and should have been reported as ordinary dividends. The distributive share of the adjustment of ordinary dividends to Partner A, an individual resident of the United Kingdom, is $1,000. Absent a treaty, Partner A would be subject to the statutory withholding of 30%. However, partner A has a valid Form W-8BEN on file with the partnership/withholding

26

agent claiming tax treaty benefits as a resident of the UK, which is subjected to the treaty rate of 15%. Since the partnership’s imputed underpayment is calculated at the default tax rate of 37%, the partnership requests modification with regard to foreign Partner A’s tax treaty benefit for U.S. source ordinary dividends at a rate of 15%. The partnership would complete Form 8980, Part VIII, as follows to request the modification based on Partner A:

The partnership should obtain and retain Form W-8BEN from Partner A, in support of the requested modification.

Column (5b): Enter the portion of Column (3) representing income exempt by statute . Enter the amount of the partner’s distributive share of partnership adjustments which are subject to the exemption indicated in column 5a.

Example 2 : Foreign Partner B has a distributive share adjustment of $1,000 interest income from Partnership ABC that is eligible for the portfolio exclusion under section 871 regarding interest on certain portfolio debt instruments. Partnership ABC would complete Form 8980, Part VIII, as follows, to request the modification based on Partner B’s Code- based exemption:

Example 3 : Foreign Partner C has a distributive share adjustment of $1,000 interest income from Partnership ABC. Partner C is an international organization within the meaning of section 7701(a)(18) and such income is within the scope of exemption granted by section 892. Partnership ABC would complete Form 8980, Part VIII, as follows, to request the modification based on Partner C’s foreign tax-exempt status:

Partnership ABC should obtain and retain Form W-8EXP from Partner C, in support of the requested modification unless other facts surrounding the payment reasonably indicate that the beneficial owner of the payment is an international organization.

Supporting Documentation for Part VIII . For each relevant partner listed in Part VIII, the partnership should secure the applicable forms (listed below) and any other documentation supporting the facts for each relevant partner’s situation. Such supporting documents will establish that the relevant partner is not a U.S. person, eligibility for treaty benefits involving a reduced rate of, or exemption from, withholding as a resident of a foreign country with which the United States has an income tax treaty, or establish other exempt status and applicable statutory exemptions from tax. If the partnership is not the withholding agent, then such forms should be obtained from the withholding agent and retained by the partnership.

Note: All forms and supporting documentation should be retained by the partnership and should be made available to the IRS upon request. Do not attach such forms to Form 8980 or otherwise send such forms to the IRS. Such supporting forms to support requested modifications in Part VIII may include:

United States; or

  • Form 8233, Exemption From Withholding on Compensation for Independent (and Certain Dependent) Personal Services of a Nonresident

Alien Individual

Requirement for Partner Affidavit of Unchanged Status . If a Form W-8 series form is not already on file with the partnership at the time the modification is requested, or the form is no longer in effect at the time the modification is requested, the partnership should solicit the applicable form from the partner. The partner should complete the current version of the form and sign with a current date. In addition, the partner must sign an “Affidavit of Unchanged Status” to declare the validity of the form, its applicability to the partnership’s reviewed year, and the partner’s entitlement to the reduction in rate or exemption from tax. Such affidavit should be attached to the completed Form W-8 series form and retained by the partnership. The following is an example of an affidavit and the suggested language:
