§ 1.1446-6. Special rules to reduce a partnership's 1446 tax with respect to a foreign partner's allocable share of effectively connected taxable income.

(i) NRA and B form a partnership (PRS) in year 4 to conduct a trade or business in the United States. NRA and B provide PRS appropriate documentation under § 1.1446-1 to establish their status for purposes of section 1446. NRA submits a certificate to PRS (using Form 8804-C) on March 20, year 4, to be considered by PRS in determining its 1446 tax due with respect to NRA for the first installment period in the year 4. The Form 8804-C states that NRA reasonably expects to have an effectively connected net operating loss of $5,000 available to offset its allocable share of ECTI from PRS in year 4. Prior to year 4, NRA had not submitted a certificate to a partnership under this section. NRA filed (or will file) its year 1 U.S. income tax return on March 11, year 3; its year 2 U.S. income tax return on February 12, year 4; its year 3 U.S. income tax return on April 13, year 4; and its year 4 U.S. income tax return on May 14, year 5. NRA paid or (will pay) all amounts due with respect to the returns (including interest, penalties, and additions to tax, if any) by the date they are filed. NRA's years 1 though 3 U.S. income tax returns report income or gain effectively connected with a U.S. trade or business or deductions or losses properly allocated and apportioned to such activities.

(ii) To be eligible to submit a certificate of deductions and losses to PRS under this section, NRA must satisfy the requirements of paragraph (b)(1) of this section. In accordance with § 1.1446-1, NRA provided valid documentation to PRS to establish its status for purposes of section 1446. NRA's year 1 U.S. income tax return is a qualifying U.S. income tax return because it reported income or gain effectively connected with a U.S. trade or business or deductions or losses properly allocated and apportioned to such activities and is described under paragraph (b)(2)(iii)(A) of this section. Although NRA filed its year 1 return after the due date of the return (determined under section 6072(c) without regard to any extension of time to file) the return was filed on March 11, year 3, which was on or before the earlier of June 15, year 3, the date one year after its section 6072(c) due date without regard to any extension of time to file, and March 20, year 4, the date on which NRA submitted the certificate to PRS. NRA's year 2 U.S. income tax return is a qualifying U.S. income tax return because it reported income or gain effectively connected with a U.S. trade or business or deductions or losses properly allocated and apportioned to such activities and is described under paragraph (b)(2)(iii)(A) of this section. Although NRA filed its year 2 return after the due date of the return (determined under section 6072(c) without regard to any extension of time to file) the return was filed on February 12, year 4, which was on or before the earlier of June 15, year 4, the date one year after its section 6072(c) due date without regard to any extension of time to file, and March 20, year 4, the date on which NRA submitted the certificate to PRS. NRA's year 3 U.S. income tax return is a qualifying U.S. income tax return because it reported income or gain effectively connected with a U.S. trade or business or deductions or losses properly allocated and apportioned to such activities and is described under paragraph (b)(2)(iii)(B) of this section. Because NRA filed its year 3 U.S. income tax return on April 13, year 4, the return will be considered timely-filed under paragraph (b)(2)(ii) of this section, as the due date under section 6072(c) was June 15, year 4. NRA's year 4 U.S. income tax return is a qualifying U.S. income tax return because it reported income or gain effectively connected with a U.S. trade or business or deductions or losses properly allocated and apportioned to such activities and is described under paragraph (b)(2)(iii)(C) of this section. Because NRA filed its year 4 U.S. income tax return on May 14, year 5, the return will be considered timely-filed under paragraph (b)(2)(ii) of this section. Accordingly, NRA meets the conditions of paragraph (b)(1) of this section and is eligible to provide a certificate of deductions and losses to PRS for year 4.

(i) Assume the same facts as in Example 1. Further, NRA and C form a second partnership (XYZ) in year 7 to conduct a trade or business in the United States. NRA and C provide XYZ appropriate documentation under § 1.1446-1 to establish their status for purposes of section 1446. NRA did not submit a certificate under this section to any partnership for years 5 and 6. NRA submits a certificate to XYZ (using Form 8804-C) on April 10, year 7, to be considered by XYZ in determining its 1446 tax due with respect to NRA for its first installment period in year 7. The certificate states that NRA reasonably expects to have an effectively connected net operating loss of $8,000 available to offset its allocable share of ECTI from XYZ in year 7. Further, the certificate contains all of the necessary representations required under this section. NRA will file its U.S. income tax return for year 5 on March 25, year 7, (after its section 6072(c) due date and any extension of time to file that could have been granted under section 6081), its U.S. income tax return for year 6 on April 26, year 7; and its U.S. income tax return for year 7 on May 27, year 8. NRA will pay all amounts due with the returns (including interest, penalties, and additions to tax, if any) by the dates they are filed. NRA's years 5, 6, and 7 U.S. income tax returns will report income or gain that is effectively connected with a U.S. trade or business or deductions or losses properly allocated and apportioned to such activities.

(ii) To be eligible to submit a certificate of deductions and losses to XYZ under this section, NRA must satisfy the requirements of paragraph (b)(1) of this section. NRA provided valid documentation to XYZ in accordance with § 1.1446-1. As described in Example 1, NRA's year 4 U.S. income tax return is a qualifying U.S. income tax return because it will report income or gain effectively connected with a U.S. trade or business and is described under paragraph (b)(2)(iii)(C) of this section. Although NRA's year 5 U.S. income tax return reports income or gain effectively connected with a U.S. trade or business or deductions or losses properly allocated and apportioned to such activities it is not a qualifying U.S. income tax return under paragraph (b)(2)(iii) of this section. Because NRA submitted a certificate to PRS in year 4, to constitute a qualifying U.S. income tax return the year 5 U.S. income tax return must be timely-filed and all amounts due with such return must be timely paid. See paragraph (b)(2)(iii)(C) of this section. However, NRA will not file its U.S. income tax return for year 5 until March 25, year 7, (after its section 6072(c) due date and any extension of time to file that could have been granted under section 6081). Because the year 5 tax return is not a qualifying U.S. income tax return under paragraph (b)(2)(iii) of this section, NRA does not satisfy the requirements of paragraph (b)(1)(ii) of this section and, therefore, may not submit a certificate of deductions and losses to XYZ under this section in year 7.

NRA and B form a partnership (PRS) to conduct a trade or business in the United States. NRA and B are equal partners under the partnership agreement. NRA and B provide PRS appropriate documentation under § 1.1446-1 to establish their status for purposes of section 1446. Prior to the formation of PRS, NRA had not invested in or engaged in the conduct of a U.S. trade or business. PRS incurs a $1,500 effectively connected net operating loss in years 1 and 2. The loss incurred in each is allocated equally between NRA and B. NRA has filed a qualifying U.S. income tax return (within the meaning of paragraph (b)(2)(iii) of this section) for years 1 and 2 that report its allocable share of effective connected net operating loss allocated to it from PRS, as reported on the Form 1065 (Schedule K-1) issued to NRA for each year.

(i) In year 3, NRA may not submit a certificate to PRS under paragraph (c) because it will not have filed qualifying U.S. income tax returns for the preceding three years. In year 3, PRS has ECTI of $1,000 that is allocated equally between NRA and B. PRS satisfies its 1446 tax obligation with respect to NRA for year 3.

(ii) In year 4, PRS estimates that it will have ECTI of $4,000, which will be allocated equally between NRA and B. On or before April 15th of year 4 (the first installment due date), NRA submits a certificate to PRS under this section (using Form 8804-C) certifying that it reasonably expects to have an effectively connected net operating loss of $1,000 ($750 loss in both years 1 and 2, less $500 of income in year 3) available to offset its allocable share of ECTI from PRS in year 4. As of the date the certificate is submitted, NRA has received the Form 1065 (Schedule K-1) from PRS for year 3 but has not yet filed its U.S. income tax return for year 3.

(iii) With respect to year 4, and based upon paragraph (b)(1) of this section, NRA can include year 3 (NRA's preceding taxable year) as one of the preceding three years that it has filed or will file qualifying U.S. income tax returns (within the meaning of paragraph (b)(2)(iii) of this section). Therefore, provided PRS has, in accordance with paragraph (a)(2) of this section, no actual knowledge or reason to know the certificate is defective, PRS may reasonably rely on NRA's certificate. Accordingly, PRS may consider NRA's certificate to reduce the 1446 tax that would otherwise be required to be paid on NRA's behalf. Specifically, subject to paragraph (c)(1)(i)(C) of this section, the $1,000 of net losses that have been reported on Forms 1065 (Schedule K-1) issued to NRA that are available to reduce NRA's U.S. income tax on NRA's allocable share of effectively connected income or gain allocable from PRS may be used to reduce the $2,000 of ECTI estimated to be allocable to NRA. As a result, PRS must pay 1446 tax on only $1,100 of NRA's allocable share of partnership ECTI for the first installment period in year 5 ($2,000−($1,000 × .90)). PRS must pay 1446 tax of $96.25 for its first installment period with respect to the ECTI allocable to NRA ($1,100 (net ECTI after considering certified losses) × .35 (withholding tax rate) × .25 (section 6655(e)(2)(B) percentage for the first installment period)). See § 1.1446-3(b)(2). Pursuant to paragraph (d)(3) of this section, PRS must attach NRA's certificate and PRS's computation of its 1446 tax obligation with respect to NRA to its Form 8813, “Partnership Withholding Tax Payment Voucher (Section 1446),” filed for the first installment period. Under paragraph (c)(2)(ii)(B) of this section, NRA is required to provide an updated certificate on or before the 10th day after NRA files its U.S. income tax return for year 3, even if the updated certificate results in no change to the amount of deductions and losses reported on the superseded certificate.

(iv) The results are the same if NRA had not yet received a Form 1065 (Schedule K-1) from PRS for year 3. See paragraph (c)(1)(i)(A) of this section.

On January 1, year 8, NRA and B form a partnership (PRS) to conduct a trade or business in the United States. NRA and B are equal partners in PRS. NRA and B provide PRS appropriate documentation under § 1.1446-1 to establish their status for purposes of section 1446. During years 1 through 7 NRA held an interest in another partnership (XYZ) that conducted a trade or business in the United States. NRA timely-filed (within the meaning of paragraph (b)(2) of this section) U.S. income tax returns for years 1 through 6 reporting its allocable share of ECTI (or loss) from XYZ (and timely paid all tax shown on such returns). NRA files its U.S. income tax return for year 7 on June 9, year 8 (and timely pays all tax due with such return). Therefore, NRA has filed qualifying U.S. income tax returns (within the meaning of paragraph (b)(2)(iii) of this section) for years 1 through 7. During years 1 through 7, NRA's only investment generating effectively connected items was its interest in XYZ. The XYZ partnership liquidated and ceased doing business on December 31, year 7.

(i) On or before April 15, year 8, PRS receives from NRA a valid certificate under this section using Form 8804-C in which NRA certifies that it reasonably expects to have available effectively connected net operating losses in the amount of $5,000. Among other statements made in accordance with paragraph (c) of this section, NRA represents that it has not yet filed its year 7 U.S. income tax return, but will timely file such return (and timely pay all tax due with such return). For its first installment period in year 8, PRS estimates that it will earn taxable income of $10,000 for the year which will be allocated equally to NRA and B (NRA's allocable share of PRS's ECTI is $5,000).

(ii) Provided PRS has, in accordance with paragraph (a)(2) of this section, no actual knowledge or reason to know the certificate is defective, PRS may reasonably rely on NRA's certificate when computing its 1446 tax obligation for the first installment period. PRS is limited under paragraph (c)(1)(i)(C) of this section and PRS may only consider $4,500 ($5,000 × .90) of the certified net operating loss. After consideration of the certified loss, PRS owes 1446 tax in the amount of $43.75 for the first installment period ($5,000 estimated allocable ECTI less $4,500 (certified loss as limited under paragraph (c)(1)(i)(C)) × .35 (1446 tax applicable percentage) × .25 (section 6655(e)(2)(B) percentage for the first installment period)). See § 1.1446-3(b)(2). Pursuant to paragraph (d)(3) of this section, PRS must attach a copy of NRA's certificate and the computation of 1446 tax due with respect to NRA to the Form 8813 filed with respect to NRA.

(iii) PRS's estimate of ECTI allocable to NRA for the second installment period remains unchanged from the first installment period. On June 10, year 8, NRA provides PRS an updated certificate reporting that NRA now reasonably expects to have an effectively connected net operating loss of $4,000 available to offset its allocable share of ECTI from PRS in year 4. NRA provided the updated certificate within 10 days of filing its U.S. income tax return for the year 7 taxable year, as required by paragraph (c)(2)(ii)(B) of this section. Provided the updated certificate is otherwise valid, PRS may rely on the updated certificate for the second installment period (due date June 15, year 8). Even if the updated certificate were not valid, PRS could no longer rely on the original certificate.

(iv) Under paragraph (d) of this section, PRS is not relieved from liability for the 1446 tax due with respect to NRA under section 1461 if it relies on a certificate determined to be defective, or if it receives an updated certificate reporting an amount of deductions and losses less than the amount reported on the superseded certificate. Under the principles of section 6655 (as applied through § 1.1446-3), PRS is required to have paid 50-percent of the annualized 1446 tax due with respect to NRA on or before the due date of the second installment period (section 6655(e)(2)(B) percentage for the second installment period). Under paragraph (c)(2)(ii)(B) of this section, because NRA's updated certificate is valid for the second installment period, if PRS considers a certificate for that period it must consider the updated certificate. Under paragraph (c)(1)(i)(C) of this section, PRS can only consider $3,600 ($4,000 × .90) of NRA's updated effectively connected net operating loss. Assuming PRS considers NRA's updated certificate for the second installment period, PRS must have paid a total of $245 of 1446 tax with respect to the ECTI estimated to be allocable to NRA as of the second installment due date ($1,400 ($5,000 ECTI less $3,600 net operating loss deduction) × .35 (withholding tax rate) × .50 (section 6655(e)(2)(B) percentage for the second installment period)). After considering PRS's payment of 1446 tax for the first installment period, PRS is required to pay $201.25 for the second installment period ($245 less previous payment of $43.75). See § 1.1446-3(b)(2). Further, if PRS considers NRA's updated certificate for the second installment period, when PRS files Form 8813 it must attach the updated certificate along with PRS's computation of 1446 tax due with respect to NRA.

(v) Under paragraph (d) of this section, PRS is not liable for the addition to the tax under section 6655 (as applied through § 1.1446-3) for the first installment period because PRS reasonably relied on NRA's certificate of losses for that period.

(vi) Assume that PRS's estimate of its ECTI allocable to NRA for the third and fourth installment periods is the same as for the first and second installment periods. Assume PRS may reasonably rely on NRA's updated certificate in calculating its payment of 1446 tax for the third and fourth installment periods. The third installment of 1446 tax would be $122.50 (($5,000 − $3,600) × .35 × .75 = $367.50 − $245 (total previous payments)). The fourth installment of 1446 tax would be $122.50 (($5,000 − $3,600) × .35 × 1.00 = $490 − $367.50 (total previous payments)). See § 1.1446-3(b)(2). PRS must attach to each Form 8813 a computation of the 1446 tax due with respect to NRA that takes into account the amount of effectively connected net operating loss reported on NRA's updated certificate.

(vii) Because NRA's certified net operating loss has not changed for the third and fourth installments, in lieu of attaching NRA's certificate, PRS may attach a statement containing NRA's name, TIN, and the certified net operating loss amount. However, PRS must attach NRA's certificate and a computation of the 1446 tax due with respect to NRA that takes into account NRA's certified net operating loss to the Form 8805 filed with respect to NRA. See paragraph (d)(3) of this section.

NRA and B form a partnership (PRS) in year 1 to conduct a trade or business in the United States. NRA and B provide PRS appropriate documentation under § 1.1446-1 to establish their status for purposes of section 1446. In year 4, NRA timely submits a certificate under this section (using Form 8804-C) to be considered by PRS for its first installment period. The certificate reports that NRA reasonably expects to have an effectively connected net operating loss of $5,000 available to offset its allocable share of ECTI from PRS in year 4. Further, the certificate contains all of the necessary representations required under this section. PRS estimates for each installment period that NRA's allocable share of ECTI will be $5,000 for the taxable year. PRS's actual operating results for the year result in $5,000 of ECTI allocable to NRA.

(i) PRS reasonably relies on (within the meaning of paragraph (a)(2) of this section) NRA's certificate when computing each installment payment during year 4 and the 1446 tax due on Form 8804 and appropriately considers the limitation in paragraph (c)(1)(i)(C) of this section. As a result, PRS paid $175 of 1446 tax on behalf of NRA for the taxable year ($5,000 of ECTI less $4,500 net operating loss deduction × .35 applicable percentage). As required under paragraph (d) of this section, PRS attached the certificate to the Form 8813 for the first installment period and the Form 8805 for year 4. Because NRA did not submit an updated certificate to PRS in year 4, PRS attached to the Forms 8813 for the second, third and fourth installment periods a statement containing NRA's name, TIN, and the certified net operating loss as well as the computation of 1446 tax due with respect to NRA reflecting the amount of net operating loss considered.

(ii) In year 5, NRA timely submits to PRS a certificate under this section to be considered for the first installment period. The certificate represents that NRA reasonably expects to have an effectively connected net operating loss of $5,000 available to offset its allocable share of ECTI from PRS in year 5. For the first installment period, PRS estimates that NRA's allocable share of partnership ECTI is $5,000. PRS reasonably relies on the certificate for the first installment period and determines that it is required to make a 1446 tax installment payment of $43.75 ($5,000 allocable ECTI less $4,500 (certified net operating loss as limited under paragraph (c)(1)(i)(C) of this section) × .35 (1446 tax applicable percentage) × .25 (section 6655(e)(2)(B) percentage for the first installment period)). See § 1.1446-3(b)(2). PRS makes the installment payment with the Form 8813 filed for the first installment period, and complies with paragraph (d)(3) of this section by attaching NRA's certificate and the computation of 1446 tax due with respect to NRA to the Form 8813.

(iii) The IRS provides written notification to PRS on June 1, year 5, (pursuant to paragraph (c)(3) of this section) that the certificate received from NRA in year 4 is defective because NRA failed to file a qualifying U.S. income tax return (within the meaning of paragraph (b)(2)(iii) of this section) for one of the preceding taxable years as required under paragraph (b)(1) of this section. The notice further states that PRS is not to rely on any certificate received from NRA in year 5.

(iv) Under paragraph (d)(2)(ii) of this section, because the certificate submitted by NRA in year was determined to be defective for a reason other than the amount or character of the certified deductions and losses, under section 1461 PRS is fully liable for the 1446 tax due with respect to NRA's allocable share of ECTI year 4 without regard to the certificate. The total 1446 tax due for year 4 without regard to the certificate is $1,750 ($5,000 ECTI × .35) and PRS paid $175 of 1446 tax in year 4. Therefore, PRS owes $1,575 of 1446 tax. However, PRS may be deemed to have paid the outstanding 1446 tax due if NRA paid all of its U.S. tax due in year 4. See § 1.1446-3(e).

(v) However, because PRS did not have actual knowledge or reason to know that the certificate NRA submitted in year 4 was defective, PRS reasonably relied on the certificate for purposes of paragraph (d)(2) of this section. Therefore, PRS is not liable for an addition to the tax with respect to its underpayment of 1446 tax under the principles of section 6655 (as applied through § 1.1446-3) for any installment period in year 4.

(vi) However, PRS is generally liable for interest under section 6601 and for the failure to pay addition to tax under section 6651(a)(2) on the $1,575 of 1446 tax due for year 4 for the period from April 15, year 5 (last date prescribed for payment of 1446 tax) to the date PRS pays the 1446 tax or is deemed to have paid the 1446 tax under § 1.1446-3(e).

(vii) With respect to the year 5, PRS reasonably relied on NRA's certificate when computing its first installment payment (due on April 15, year 5). Therefore, in accordance with paragraph (d)(2)(i) of this section, PRS will not be liable for an addition to the tax under the principles of section 6655 (as applied through § 1.1446-3) for the first installment period. However, because the IRS provided written notification to PRS on June 1, year 5, to disregard any certificate received from NRA for year 5, PRS may not rely on any certificate received from NRA certificate (or any new certificate provided by NRA) when it computes its second installment payment in year 5. PRS is not permitted to consider any certificate submitted by NRA until the IRS provides written notification to PRS revoking or modifying the original notice. PRS's second installment payment in year 5 must include the additional amount of 1446 tax it would have paid for the first installment period without regard to the certificate received from NRA.

Assume the same facts as in Example 5, except that the IRS determines that NRA's certificate submitted in year 4 is defective because the actual effectively connected net operating loss available to NRA for year 4 was $1,000 rather than the $5,000 certified.

(i) Under paragraph (d)(2)(ii) of this section, PRS is not relieved from its liability for 1446 tax under section 1461 when it relies on a certificate of losses from a foreign partner that is later determined to be defective. However, when the IRS determines that a partner's certificate is defective because of the amount of the certified deductions and losses, the partnership is liable for the 1446 tax, interest, additions to tax, and penalties to the extent the amount of certified deductions and losses taken into account when computing 1446 tax (or, unless there was reasonable reliance on the certificate, any installment of such tax) is greater than the actual amount of available deductions and losses. Here, PRS considered the certified deductions and losses in the amount of $4,500. The IRS subsequently determined that NRA only had $1,000 of actual losses, only $900 of which were permitted to be considered under paragraph (c)(1)(i)(C) of this section. Accordingly, PRS is liable for the 1446 tax due with respect to the portion of the overstated losses that it considered when computing its 1446 tax. The remaining 1446 tax due for year 4 is $1,260 ($3,600 ($4,500 less $900) of excess losses considered × .35). However, PRS may be deemed to have paid the $1,260 of 1446 tax under § 1.1446-3(e) if NRA has paid all of NRA's U.S. income tax.

(ii) If PRS had considered only $900 (or a lesser amount) of NRA's certified net operating loss when computing and paying its 1446 tax during year 4 then, under paragraph (d)(2)(iii) of this section, PRS would not be liable for 1446 tax because it did not consider a net operating loss greater than the amount actually available to NRA.

PRS partnership has two equal partners, FC, a foreign corporation, and DC, a domestic corporation. PRS conducts a trade or business in the United States and generates effectively connected income. FC maintains a June 30 fiscal taxable year end, while DC and PRS maintain a calendar taxable year end. FC and DC provide a valid Form W-8BEN and Form W-9, respectively, to PRS. FC and DC are the only persons that have ever been partners in PRS. For its year 1 through year 3 taxable years, PRS issued Forms 1065 (Schedule K-1) reporting in the aggregate $100 of net loss to each partner. For its year 4 taxable year, PRS issued Forms 1065 (Schedule K-1) to its partners reporting $150 of loss to each partner. All of the losses reported on the Forms 1065 (Schedule K-1) are effectively connected to PRS's and FC's trade or business in the United States.

(i) Assume that FC submits a valid certificate under this section certifying losses to the partnership for the partnership's year 5 taxable year. Further, assume that FC's only source of effectively connected income, gain, deduction, or loss is the activity of PRS.

(ii) For PRS's first installment period in year 5, FC may only certify deductions and losses under this section in the amount of $100 (the losses as reported on the Forms 1065 (Schedule K-1) issued for PRS's year 1 through 3 taxable years). Under section 706, the taxable income of a partner shall include the income, gain, loss, deduction, or credit of the partnership for the partnership taxable year ending within or with the taxable year of the partner. PRS's year 4 calendar taxable year ends during FC's fiscal taxable year ending June 30, year 5. Therefore, under paragraph (c)(1) of this section, as of April 15, year 5 (the last date FC may submit its first certificate under paragraph (c) of this section to have it considered for PRS's first installment due date of April 15, year 5), FC's allocable share of the PRS losses for years 1 through 3 are the only losses that FC can represent have been or will be reported on an FC U.S. income tax return filed for a taxable year ending prior to such installment due date.

(iii) The result in paragraph (ii) of this Example 7 is the same for the year 5 second installment period, the due date of which is June 15, year 5.

(iv) FC may submit an updated certificate under this section after June 30, year 5, which includes the $150 loss for year 4. PRS may consider such an updated certificate for its third installment period (due date September 15, year 5), provided the updated certificate is received by the due date for such installment in accordance with paragraph (c) of this section.

FC, a foreign corporation, and DC, a domestic corporation, form a partnership (PRS) to conduct a trade or business in the United States. FC and DC provide PRS appropriate documentation under § 1.1446-1 to establish their status for purposes of section 1446. FC and DC are equal partners in PRS, and all partnership items are allocated equally between FC and DC.

(i) In the current taxable year FC submits a certificate under this section using Form 8804-C prior to PRS's first installment due date. FC represents that it has filed or will file a qualifying U.S. income tax return (within the meaning of paragraph (b)(2)(iii) of this section) in each of the preceding three taxable years. FC specifies that it has not filed its U.S. income tax return for the immediately preceding taxable year. FC also represents that it will timely file its U.S. income tax return for the partnership taxable year during which the certificate is considered (and will timely pay all tax due with such return). Assume all other requirements under paragraph (c) of this section are met for FC's certificate to be valid.

(ii) Provided that PRS does not possess actual knowledge or reason to know that FC's certificate is defective under paragraph (a)(2) of this section, PRS may reasonably rely on FC's certificate for its first, second, and third installment payments.

(iii) If FC does not submit to PRS either an updated certificate or a status update as required by paragraph (c)(2)(ii)(B)(1) of this section by December 15th (PRS's final installment due date), PRS must disregard FC's certificate when computing its fourth installment payment of 1446 tax and when completing its Form 8804 for the taxable year. PRS's payment of 1446 tax for its fourth installment period must include the additional amount of 1446 tax it would have paid in the first, second and third installment periods had it not considered FC's certificate. Further, even if the status update is provided by December 15th, PRS may only rely on the certificate if the status update does not contradict the original certificate and such update indicates that the immediately preceding year's return will be timely filed. Finally, even if the status update is provided by December 15th, FC must also submit an updated certificate to the partnership in accordance with paragraph (c) of this section within 10 days of the date FC timely files its U.S. income tax return for the preceding taxable year.

For purposes of this example assume paragraph (c)(1)(ii) of this section may apply. On January 1, year 4, NRA and B form a partnership (PRS) to conduct a trade or business in the United States. NRA and B are equal partners in PRS and all partnership items are shared equally. NRA and B provide PRS appropriate documentation under § 1.1446-1 to establish their status for purposes of section 1446. During years 1 through 3, NRA's only activity generating effectively connected items was an interest in partnership XYZ. XYZ allocated NRA a loss for all three years. NRA filed qualifying U.S. income tax returns (within the meaning of paragraph (b)(2)(iii) of this section) reporting its allocable share of losses from XYZ in years 1 through 3. The XYZ partnership dissolved on December 31, year 3.

(i) In year 4, NRA's only activity giving rise to effectively connected income, gain, deduction, or loss is its interest in PRS. NRA submits to PRS a valid certificate (using Form 8804-C) certifying under paragraph (c)(1)(i) its effectively connected net operating losses from years 1 through 3 and under (c)(1)(ii) of this section that its only activity giving rise to effectively connected income, gain, deduction, or loss for the PRS taxable year that ends with or within its taxable year is (and will be) its investment in PRS.

(ii) During year 4, PRS allocates ECTI to NRA. If the 1446 tax otherwise due on the annualized amount allocated to NRA is less than $1,000, determined without regard to any deductions and losses certified by NRA under paragraph (c)(1)(i) of this section, PRS may consider the certificate received from NRA under paragraph (c)(1)(ii) of this section and not pay 1446 tax (or any installment of such tax) with respect to NRA. Alternatively, PRS may consider the deductions and losses certified by NRA under paragraph (c)(1)(i) of this section.

(iii) Regardless of whether PRS considers NRA's certification under paragraph (c)(1)(i) or (c)(1)(ii) of this section in computing its 1446 tax due with respect to NRA, PRS must file Form 8813 for all installment periods as well as a Form 8805 for NRA with its Form 8804. If PRS considers NRA's certification under paragraph (c)(1)(i) or (c)(1)(ii) of this section, PRS must attach to each Form 8813, as well as to the Form 8805, a computation of the 1446 tax with respect to NRA that takes into account its consideration of NRA's certificate. In addition, PRS must attach NRA's certificate to the Form 8813 for the first installment period it considers the certificate, as well as to the Form 8805. For all subsequent installment periods, PRS may attach a statement containing NRA's name, and TIN. If PRS is relying on NRA's certified losses under paragraph (c)(1)(i) of this section, the statement must indicate the amount of losses and deductions NRA certified. If PRS is relying on NRA's certification under paragraph (c)(ii) of this section, the statement must indicate that it is relying on NRA meeting the requirements under paragraph (c)(1)(ii) of this section and the 1446 tax on the annualized amount allocated to NRA is less than $1,000. See paragraph (d)(3)(i) of this section.

NRA and B form a partnership (PRS) on January 1, 2004, to conduct a trade or business in the United States. NRA and B are equal partners in PRS and all partnership items are shared equally. NRA and B provide PRS appropriate documentation under § 1.1446-1 to establish their status for purposes of section 1446. For its 2004 through 2007 tax years, PRS issued Forms 1065 (Schedule K-1) to NRA and B reporting a $1,000 net loss from its U.S. trade or business to each partner for each year (for an aggregate loss of $4,000 per partner). During the 2004 through 2007 tax years, NRA's only activity generating effectively connected items was its investment in PRS.

(i) On February 10, 2008, NRA submitted a certificate to PRS, reporting its aggregate $4,000 effectively connected loss to PRS, that met the requirements of § 1.1446-6T(c) (See 26 CFR Part 1, revised as of April 1, 2007), as in effect before January 1, 2008. The certificate stated that NRA had timely filed its U.S. income tax returns for the 2004, 2005 and 2006 tax years, and that it would timely file a U.S. income tax return for its 2007 tax year. For the first and second installments period in 2008, PRS estimates that it will earn ECTI of $10,000.

(ii) Because the certificate submitted by NRA to PRS on February 10, 2008, met the requirements of § 1.1446-6T (See 26 CFR Part 1, revised as of April 1, 2007), as in effect before January 1, 2008, PRS may consider such certificate when computing its 1446 tax due for the first and second installment period even if the certificate does not meet all the requirements of paragraph (c) of this section.

(iii) NRA timely files its U.S. income tax return for the 2007 tax year on July 24, 2008. In accordance with paragraph (c)(2)(ii)(B)(1) of this section, within 10 days of filing such return NRA prepares an updated certificate to be submitted to PRS certifying that it reasonably expects to have only $3,500 of losses available to reduce its allocable share of ECTI from PRS. Because the updated certificate will be submitted after July 28, 2008, to be valid the updated certificate must meet the requirements of paragraph (c) this section.
