(a) Transferee's obligation to withhold. Except as otherwise provided in this section, a transferee is required to withhold under section 1446(f)(1) a tax equal to 10 percent of the amount realized on any transfer of a partnership interest. This section does not apply to a transfer of a PTP interest that is effected through one or more brokers, including a distribution made with respect to a PTP interest held in an account with a broker. For rules regarding those transfers, see § 1.1446(f)-4.

(b) Exceptions to withholding—(1) In general. A transferee is not required to withhold under this section if it properly relies on a certification or its books and records as described in this paragraph (b). A transferee may not rely on a certification if it has actual knowledge that the certification is incorrect or unreliable. A partnership that is a transferee because it makes a distribution may not rely on its books and records if it knows, or has reason to know, that the information is incorrect or unreliable.

(2) Certification of non-foreign status by transferor. A transferee may rely on a certification of non-foreign status from the transferor that states that the transferor is not a foreign person, states the transferor's name, TIN, and address, and is signed under penalties of perjury. For purposes of this paragraph (b)(2), a certification of non-foreign status includes a valid Form W-9, Request for Taxpayer Identification Number and Certification. For purposes of this paragraph (b)(2), a transferee may rely on a valid Form W-9 from the transferor that it already possesses if the form meets the requirements of this paragraph (b)(2).

(3) No realized gain by transferor—(i) In general. A transferee (other than a partnership that is a transferee because it makes a distribution) may rely on a certification from the transferor that states that the transfer of the partnership interest would not result in any realized gain (including ordinary income arising from the application of section 751 and § 1.751-1) to the transferor as of the determination date (see § 1.1446(f)-1(c)(4)). See paragraph (b)(6) of this section for rules that apply when the transferor realizes gain but is not required to recognize the gain under a provision of the Internal Revenue Code.

(ii) No section 751 income. For purposes of paragraph (b)(3)(i) of this section, a transferor may rely on a certification from the partnership stating that the transfer of the partnership interest would not result in any ordinary income arising from the application of section 751 and § 1.751-1 to the transferor as of the determination date. The certification from the partnership must be attached to, and forms part of, the certification of no realized gain that the transferor provides to the transferee.

(iii) Partnership distributions. A partnership that is a transferee because it makes a distribution may rely on its books and records, or on a certification from the transferor, to determine that the distribution would not result in any realized gain to the transferor as of the determination date.

(4) Less than 10 percent effectively connected gain—(i) In general. A transferee (other than a partnership that is a transferee because it makes a distribution) may rely on a certification from the partnership that states that—

(A) If the partnership sold all of its assets at fair market value as of the determination date in the manner described in § 1.864(c)(8)-1(c), either—

(1) The partnership would have no gain that would have been effectively connected with the conduct of a trade or business within the United States, or, if the partnership would have a net amount of such gain, the amount of the partnership's net gain that would have been effectively connected with the conduct of a trade or business within the United States would be less than 10 percent of the total net gain; or

(2) The transferor would not have a distributive share of net gain from the partnership that would have been effectively connected with the conduct of a trade or business in the United States, or, if the transferor would have a distributive share of such gain from the partnership, the transferor's distributive share of net gain from the partnership that would have been effectively connected with the conduct of a trade or business within the United States would be less than 10 percent of the transferor's distributive share of the total net gain from the partnership; or

(B) The partnership was not engaged in a trade or business within the United States at any time during the taxable year of the partnership through the date of transfer.

(ii) Partnership distributions. A partnership that is a transferee because it makes a distribution may rely on its books and records to determine that paragraph (b)(4)(i)(A) of this section is satisfied as of the determination date or paragraph (b)(4)(i)(B) of this section is satisfied for the taxable year of the partnership through the date of transfer.

(5) Less than 10 percent effectively connected income—(i) In general. A transferee (other than a partnership that is a transferee because it makes a distribution) may rely on a certification from the transferor that states that—

(A) The transferor was a partner in the partnership throughout the look-back period described in paragraph (b)(5)(ii) of this section;

(B) The transferor's distributive share of gross effectively connected income from the partnership, as reported on a Schedule K-1 (Form 1065), Partner's Share of Income, Deductions, Credits, etc., or other statement required to be furnished under § 1.6031(b)-1T, including any gross effectively connected income included in the distributive share of a partner that bears a relationship to the transferor described in section 267(b) or 707(b)(1), was less than $1 million for each of the taxable years within the look-back period described in paragraph (b)(5)(ii) of this section;

(C) The transferor's distributive share of gross effectively connected income from the partnership, as reported on a Schedule K-1 (Form 1065), or other statement required to be furnished under § 1.6031(b)-1T, for each of the taxable years within the look-back period described in paragraph (b)(5)(ii) of this section, was less than 10 percent of the transferor's total distributive share of gross income from the partnership for that year as determined under subchapter K of the Internal Revenue Code (as provided on a Schedule K-1 (Form 1065) or other statement required to be furnished under § 1.6031(b)-1T); and

(D) The transferor's distributive share of income or gain from the partnership that is effectively connected with the conduct of a trade or business within the United States or deductions or losses properly allocated and apportioned to that income in each of the taxable years within the look-back period described in paragraph (b)(5)(ii) of this section has been reported on a Federal income tax return (either filed by the transferor or, in the case of transferor that is a partnership, filed by its direct or indirect nonresident alien individual or foreign corporate partners) on or before the due date (including extensions), and all amounts due with respect to the reported amounts have been timely paid to the IRS, provided that the return was required to be filed when the transferor furnishes the certification (taking into account any extensions of time to file).

(ii) Look-back period—(A) In general. The transferor's look-back period is the transferor's immediately prior taxable year and the two preceding taxable years.

(B) Immediately prior taxable year. The transferor's immediately prior taxable year is the transferor's most recent taxable year—

(1) With or within which a taxable year of the partnership ended; and

(2) For which a Schedule K-1 (Form 1065) was due (including extensions) or furnished (if earlier) before the transfer.

(C) Limitation. A transferee may not rely on a certification that is provided before the transferor's receipt of the Schedule K-1 (Form 1065) described in paragraph (b)(5)(ii)(B) of this section.

(iii) No distributive share of gross income. A transferor that did not have a distributive share of gross income in any year described in paragraph (b)(5)(ii)(A) of this section cannot provide the certification described in this paragraph (b)(5).

(iv) Partnership distributions. A partnership that is a transferee by reason of making a distribution may rely on its books and records to determine that the requirements in paragraphs (b)(5)(i)(A) through (C) of this section have been satisfied (subject to the rules in paragraphs (b)(5)(ii) and (iii) of this section). The partnership must also obtain a representation from the transferor stating that the requirement in paragraph (b)(5)(i)(D) of this section has been satisfied.

(6) Certification of nonrecognition by transferor—(i) In general. A transferee may rely on a certification from the transferor that states that by reason of the operation of a nonrecognition provision of the Internal Revenue Code the transferor is not required to recognize any gain or loss with respect to the transfer. The certification must briefly describe the transfer and provide the relevant law and facts relating to the certification.

(ii) Partial nonrecognition. Paragraph (b)(6)(i) of this section does not apply if only a portion of the gain realized on the transfer is subject to a nonrecognition provision. However, see paragraph (c)(4)(v) of this section for rules applicable to a transferor's claim for partial nonrecognition.

(7) Income tax treaties—(i) In general. A transferee may rely on a certification from the transferor that states that the transferor is not subject to tax on any gain from the transfer pursuant to an income tax treaty in effect between the United States and a foreign country if the requirements of this paragraph (b)(7) are met. The transferor makes the certification on a withholding certificate (on a Form W-8BEN, Certificate of Foreign Status of Beneficial Owner for United States Tax Withholding and Reporting (Individuals), or Form W-8BEN-E, Certificate of Status of Beneficial Owner for United States Tax Withholding and Reporting (Entities)) that meets the requirements for validity under § 1.1446-1(c)(2)(iv) (or an applicable substitute form that meets the requirements under § 1.1446-1(c)(5)) and that contains the information necessary to support the claim for treaty benefits. A transferee may rely on a certification of treaty benefits only if, within 30 days after the date of the transfer, the transferee mails a copy of the certification to the Internal Revenue Service, at the address provided in § 1.1445-1(g)(10), together with a cover letter providing the name, TIN, and address of the transferee and the partnership in which an interest was transferred.

(ii) Treaty claim for less than all of the gain. Paragraph (b)(7)(i) of this section does not apply if treaty benefits apply to only a portion of the gain from the transfer. However, see paragraph (c)(4)(vi) of this section for rules applicable to situations in which treaty benefits apply to only a portion of the gain.

(iii) Exclusive means to claim an exception from withholding based on treaty benefits. A transferor claiming treaty benefits with respect to all of the gain from the transfer must use the exception in this paragraph (b)(7) and not any other exception or determination procedure in paragraphs (b) and (c) of this section to claim an exception to withholding by reason of a claim of treaty benefits.

(c) Determining the amount to withhold—(1) In general. A transferee that is required to withhold under this section must withhold 10 percent of the amount realized on the transfer of the partnership interest, except as otherwise provided in this paragraph (c). Any procedures in this paragraph (c) apply solely for purposes of determining the amount to withhold under section 1446(f)(1) and this section. A transferee may not rely on a certification if it has actual knowledge that the certification is incorrect or unreliable. A partnership that is a transferee because it makes a distribution may not rely on its books and records if it knows, or has reason to know, that the information is incorrect or unreliable.

(2) Amount realized—(i) In general. The amount realized on the transfer of the partnership interest is determined under section 1001 (including §§ 1.1001-1 through 1.1001-5) and section 752 (including §§ 1.752-1 through 1.752-7). Thus, the amount realized includes the amount of cash paid (or to be paid), the fair market value of other property transferred (or to be transferred), the amount of any liabilities assumed by the transferee or to which the partnership interest is subject, and the reduction in the transferor's share of partnership liabilities. In the case of a distribution, the amount realized is the sum of the amount of cash distributed (or to be distributed), the fair market value of property distributed (or to be distributed), and the reduction in the transferor's share of partnership liabilities.

(ii) Alternative procedures for transferee to determine share of partnership liabilities—(A) In general. A transferee (other than a partnership that is a transferee because it makes a distribution), as an alternative to determining the share of partnership liabilities under paragraph (c)(2)(i) of this section, may use the procedures of this paragraph (c)(2)(ii) to determine the extent to which a reduction in partnership liabilities is included in the amount realized.

(B) Certification of liabilities by transferor. Except as otherwise provided in this section, a transferee may rely on a certification from a transferor, other than a controlling partner, that provides the amount of the transferor's share of partnership liabilities reported on the most recent Schedule K-1 (Form 1065) issued by the partnership. If the transferor's actual share of liabilities at the time of the transfer differs from the amount reported on that Schedule K-1 (Form 1065), the certification will not be treated as incorrect or unreliable if the transferor also certifies that it does not have actual knowledge of any events occurring after receiving the Schedule K-1 (Form 1065) and before the date of the transfer that would cause the amount of the transferor's share of partnership liabilities at the time of the transfer to differ by more than 25 percent from the amount shown on the Schedule K-1 (Form 1065). A transferee may not rely on a certification if the last day of the partnership taxable year for which the Schedule K-1 (Form 1065) was provided was more than 22 months before the date of the transfer.

(C) Certification of liabilities by partnership. A transferee may rely on a certification from a partnership that provides the amount of the transferor's share of partnership liabilities on the determination date. If the transferor's actual share of liabilities at the time of the transfer differs from the amount on the certification, the certification will not be treated as incorrect or unreliable if the partnership also certifies that it does not have actual knowledge of any events occurring after the determination date and before the date on which the partnership provides the certification to the transferee that would cause the amount of the transferor's share of partnership liabilities at the time of the transfer to differ by more than 25 percent from the amount shown on the certification by the partnership for the determination date.

(iii) Partnership's determination of partnership liabilities for distributions. A partnership that is a transferee because it makes a distribution may rely on its books and records to determine the extent to which the transferor's share of partnership liabilities on the determination date are included in the amount realized. The information in the books and records will not be treated as incorrect or unreliable unless the partnership has actual knowledge, on or before the date of the distribution, of any events occurring after the determination date that would cause the amount of the transferor's share of partnership liabilities at the time of the transfer to differ by more than 25 percent from the amount determined by the partnership as of the determination date.

(iv) Certification by a foreign partnership of modified amount realized—(A) In general. When a transferor is a foreign partnership, a transferee may use the procedures of this paragraph (c)(2)(iv) to determine the amount realized. For purposes of this paragraph (c)(2)(iv)(A), the transferee may treat the modified amount realized as the amount realized to the extent that it may rely on a certification from the transferor providing the modified amount realized.

(B) Determining modified amount realized. The modified amount realized is determined by multiplying the amount realized (as determined under this paragraph (c)(2), without regard to this paragraph (c)(2)(iv)) by the aggregate percentage computed as of the determination date. The aggregate percentage is the percentage of the gain (if any) arising from the transfer that would be allocated to presumed foreign taxable persons. For purposes of this paragraph (c)(2)(iv)(B), a presumed foreign taxable person is any direct or indirect partner of the transferor that has not provided either a certification of non-foreign status that meets the requirements of paragraph (b)(2) of this section or a certification of treaty benefits that states that the partner is not subject to tax on any gain from the transfer pursuant to an income tax treaty in effect between the United States and a foreign country. A valid certification of treaty benefits must meet the requirements of paragraph (b)(7) of this section (as applied to the partner claiming treaty benefits), including the requirement that the transferee mail a copy of the certification to the IRS within the time prescribed. For purposes of this paragraph (c)(2)(iv), an indirect partner is a person that owns an interest in the transferor indirectly through one or more foreign partnerships.

(C) Certification. The certification is made by providing a withholding certificate (on Form W-8IMY, Certificate of Foreign Intermediary, Foreign Flow-Through Entity, or Certain U.S. Branches for United States Tax Withholding and Reporting) that includes a withholding statement that provides the percentage of gain allocable to each direct or indirect partner and that provides whether each such person is a United States person, a foreign partner eligible for treaty benefits, or a presumed foreign taxable person. The certification must also include the certification of non-foreign status or the certification of treaty benefits from each direct or indirect partner that is not a presumed foreign taxable person.

(3) Lack of money or property or lack of knowledge regarding liabilities. The amount to withhold equals the amount realized determined without regard to any decrease in the transferor's share of partnership liabilities if—

(i) The amount otherwise required to be withheld under this paragraph (c) would exceed the amount realized determined without regard to the decrease in the transferor's share of partnership liabilities; or

(ii) The transferee is unable to determine the amount realized because it does not have actual knowledge of the transferor's share of partnership liabilities (and has not received or cannot rely on a certification described in paragraph (c)(2)(ii)(B) or (C) of this section).

(4) Certification of maximum tax liability—(i) In general. A transferee may use the procedures of this paragraph (c)(4) for determining the amount to withhold for purposes of section 1446(f)(1) and paragraph (a) of this section. A transferee (other than a partnership that is a transferee because it makes a distribution) may rely on a certification from a transferor that is a foreign corporation, a nonresident alien individual, a foreign partnership, or a foreign trust regarding the transferor's maximum tax liability as described in paragraph (c)(4)(ii) of this section. A partnership that is a transferee because it makes a distribution may instead rely on its books and records to determine the transferor's maximum tax liability if the books and records includes the information required by paragraphs (c)(4)(iii) and (iv) of this section. A transferor that is a foreign partnership or a foreign trust is treated as a nonresident alien individual for purposes of determining the transferor's maximum tax liability.

(ii) Maximum tax liability. For purposes of this paragraph (c)(4), the term maximum tax liability means the amount of the transferor's effectively connected gain (as determined under paragraph (c)(4)(iii)(E) of this section) multiplied by the applicable percentage, as defined in § 1.1446-3(a)(2).

(iii) Required information. The certification must include—

(A) A statement that the transferor is either a nonresident alien individual, a foreign corporation, a foreign partnership, or a foreign trust;

(B) The transferor's adjusted basis in the transferred interest on the determination date;

(C) The transferor's amount realized (determined in accordance with paragraph (c)(2) of this section) on the determination date;

(D) Whether the transferor remains a partner immediately after the transfer;

(E) The amount of outside ordinary gain and outside capital gain that would be recognized and treated as effectively connected gain under § 1.864(c)(8)-1(b) on the determination date (effectively connected gain);

(F) The transferor's maximum tax liability on the determination date;

(G) A representation from the transferor that the transferor determined the amounts described in paragraph (c)(4)(iii)(E) of this section based on the statement described in paragraph (c)(4)(iv) of this section, if applicable; and

(H) A representation from the transferor that it has provided the transferee with a copy of the statement described in paragraph (c)(4)(iv) of this section.

(iv) Partnership statement. A transferor may make the representation in paragraph (c)(4)(iii)(G) of this section only if the partnership provides to the transferor a statement (that meets the requirements for a certification under the general rules for applicability in § 1.1446(f)-1(c)) that includes—

(A) The partnership's name, address, and TIN; and

(B) The transferor's aggregate deemed sale EC ordinary gain, within the meaning of § 1.864(c)(8)-1(c)(3)(ii)(A) (if any) and the transferor's aggregate deemed sale EC capital gain, within the meaning of § 1.864(c)(8)-1(c)(3)(ii)(B) (if any), in each case, on the determination date.

(v) Partial nonrecognition. If a nonrecognition provision applies to only a portion of the gain realized on the transfer, a certification described in paragraph (c)(4)(i) may be relied upon only if the certification also includes the information required in paragraph (b)(6) of this section (substituting “a portion of the gain or loss” for “any gain or loss” in paragraph (b)(6)(i) of this section).

(vi) Income tax treaties. If only a portion of the gain on the transfer is not subject to tax pursuant to an income tax treaty in effect between the United States and a foreign country, a certification described in paragraph (c)(4)(i) of this section may be relied upon only if the requirements of paragraph (b)(7)(i) of this section have been met, including the requirement to obtain the applicable withholding certificate indicating that the gain from the transfer is not subject to tax pursuant to an income tax treaty (substituting “a portion of the gain” for “any gain” in paragraph (b)(7)(i) of this section), and the requirement to mail a copy of the withholding certificate to the IRS.

(d) Reporting and paying withheld amounts—(1) In general. A transferee required to withhold under this section must report and pay any tax withheld by the 20th day after the date of the transfer using Forms 8288, U.S. Withholding Tax Return for Dispositions by Foreign Persons of U.S. Real Property Interests, and 8288-A, Statement of Withholding on Dispositions by Foreign Persons of U.S. Real Property Interests, in accordance with the instructions to those forms. The IRS will stamp Form 8288-A to show receipt and mail a stamped copy to the transferor (at the address reported on the form). See paragraph (e)(2) of this section for the procedures for the transferor to claim a credit for amounts withheld. Forms 8288 and 8288-A must include the TINs of both the transferor and the transferee. If any required TIN is not provided, the transferee must still report and pay any tax withheld on Form 8288.

(2) Certification of withholding to partnership for purposes of section 1446(f)(4). A transferee (other than a partnership that is a transferee because it makes a distribution) must certify to the partnership the extent to which it has satisfied its obligation to withhold under this section no later than 10 days after the transfer. The certification must either include a copy of Form 8288-A that the transferee files with respect to the transfer, or state the amount realized and the amount withheld on the transfer. The certification must also include any certifications that the transferee relied on to apply an exception to withholding under paragraph (b) of this section or to determine the amount to withhold under paragraph (c) of this section. A transferee that relied on a certification to apply an exception or adjustment to withholding remains liable under this section when the partnership knows, or has reason to know, that the certification is incorrect or unreliable. See § 1.1446(f)-3 for rules regarding a partnership's obligation to withhold on distributions to a transferee when this certification establishes only partial satisfaction of the required amount, is not provided, or cannot be relied upon.

(e) Effect of withholding on transferor—(1) In general. The withholding of tax by a transferee under this section does not relieve a foreign person from filing a U.S. tax return with respect to the transfer. See §§ 1.6012-1(b)(1), 1.6012-2(g)(1), and 1.6031(a)-1. Further, the withholding of tax by a transferee does not relieve a nonresident alien individual or foreign corporation subject to tax on gain by reason of section 864(c)(8) from paying any tax due with the return that has not been fully satisfied through withholding.

(2) Manner of obtaining credit—(i) Individuals or corporations. Except as provided in paragraph (e)(3) of this section, an individual or corporation may claim a credit under section 33 for the amount withheld under this section by attaching to its applicable return the stamped copy of Form 8288-A provided to it under paragraph (d)(1) of this section.

(ii) Partnerships, trusts, or estates. For a rule allowing a foreign partnership that is a transferor to claim a credit for the amount withheld under this section against its tax liability under section 1446(a), see § 1.1446-3(c)(4). For the rule providing the extent to which a foreign trust or estate may claim a credit for an amount withheld under this section, see § 1.1462-1. Except as provided in paragraph (e)(3) of this section, a foreign partnership, trust, or estate claiming a credit for an amount withheld must attach to its applicable return the stamped copy of Form 8288-A provided to it under paragraph (d)(1) of this section. A foreign trust or estate must also provide any other information required in forms or instructions to any beneficiary or owner that is liable for tax on any of the gain under section 864(c)(8).

(3) Failure to receive Form 8288-A. If a stamped copy of Form 8288-A has not been provided to the transferor by the IRS, the transferor may establish the amount of tax withheld by the transferee by attaching to its return substantial evidence of the amount. The transferor must attach to its return a statement that includes all of the information otherwise required to be provided on Form 8288-A.

(f) Applicability date. This section applies to transfers that occur on or after January 29, 2021.
