§ 1.874-1. Allowance of deductions and credits to nonresident alien individuals.

In Year 1, A became a limited partner with a passive investment in a U.S. limited partnership that was engaged in a U.S. trade or business. During Year 1 through Year 4, A incurred losses with respect to A's U.S. partnership interest. A's foreign tax advisor incorrectly concluded that because A was a limited partner and had only losses from A's partnership interest, A was not required to file a U.S. income tax return. A was aware neither of A's obligation to file a U.S. income tax return for those years nor of A's ability to file a protective return for those years. A had never filed a U.S. income tax return before. In Year 5, A began realizing a profit rather than a loss with respect to the partnership interest and, for this reason, engaged a U.S. tax advisor to handle A's responsibility to file U.S. income tax returns. In preparing A's U.S. income tax return for Year 5, A's U.S. tax advisor discovered that returns were not filed for Year 1 through Year 4. Therefore, with respect to those years for which applicable filing deadlines in paragraph (b)(1) of this section were not met, A would be barred by paragraph (a) of this section from claiming any deductions that otherwise would have given rise to net operating losses on returns for these years, and that would have been available as loss carryforwards in subsequent years. At A's direction, A's U.S. tax advisor promptly contacted the appropriate examining personnel and cooperated with the Internal Revenue Service in determining A's income tax liability, for example, by preparing and filing the appropriate income tax returns for Year 1 through Year 4 and by making A's books and records available to an Internal Revenue Service examiner. A has met the standard described in paragraph (b)(2) of this section for waiver of any applicable filing deadlines in paragraph (b)(1) of this section.

Same facts as in Example 1, except that while A's U.S. tax advisor contacted the appropriate examining personnel and filed the appropriate income tax returns for Year 1 through Year 4, A refused all requests by the Internal Revenue Service to provide supporting information (for example, books and records) with respect to those returns. Because A did not cooperate in determining A's U.S. tax liability for the taxable years for which an income tax return was not timely filed, A is not granted a waiver as described in paragraph (b)(2) of this section of any applicable filing deadlines in paragraph (b)(1) of this section.

Same facts as in Example 1, except that in Year 1 through Year 4, A also consulted a U.S. tax advisor, who advised A that it was uncertain whether U.S. income tax returns were necessary for those years and that A could protect A's right subsequently to claim the loss carryforwards by filing protective returns under paragraph (b)(6) of this section. A did not file U.S. income tax returns or protective returns for those years. A did not present evidence that intervening events beyond A's control prevented A from filing an income tax return, and there were no other mitigating factors. A has not met the standard described in paragraph (b)(2) of this section for waiver of any applicable filing deadlines in paragraph (b)(1) of this section.

In Year 1, A, a computer programmer, opened an office in the United States to market and sell a software program that A had developed outside the United States. A had minimal business or tax experience internationally, and no such experience in the United States. Through A's personal efforts, U.S. sales of the software produced income effectively connected with a U.S. trade or business. A, however, did not file U.S. income tax returns for Year 1 or Year 2. A was aware neither of A's obligation to file a U.S. income tax return for those years, nor of A's ability to file a protective return for those years. A had never filed a U.S. income tax return before. In November of Year 3, A engaged U.S. counsel in connection with licensing software to an unrelated U.S. company. U.S. counsel reviewed A's U.S. activities and advised A that A should have filed U.S. income tax returns for Year 1 and Year 2. A immediately engaged a U.S. tax advisor who, at A's direction, promptly contacted the appropriate examining personnel and cooperated with the Internal Revenue Service in determining A's income tax liability, for example, by preparing and filing the appropriate income tax returns for Year 1 and Year 2 and by making A's books and records available to an Internal Revenue Service examiner. A has met the standard described in paragraph (b)(2) of this section for waiver of any applicable filing deadlines in paragraph (b)(1) of this section.

In Year 1, A, a computer programmer, opened an office in the United States to market and sell a software program that A had developed outside the United States. Through A's personal efforts, U.S. sales of the software produced income effectively connected with a U.S. trade or business. A had extensive experience conducting similar business activities in other countries, including making the appropriate tax filings. A, however, was aware neither of A's obligation to file a U.S. income tax return for those years, nor of A's ability to file a protective return for those years. A had never filed a U.S. income tax return before. Despite A's extensive experience conducting similar business activities in other countries, A made no effort to seek advice in connection with A's U.S. tax obligations. A failed to file either U.S. income tax returns or protective returns for Year 1 and Year 2. In November of Year 3, an Internal Revenue Service examiner asked A for an explanation of A's failure to file U.S. income tax returns. A immediately engaged a U.S. tax advisor, and cooperated with the Internal Revenue Service in determining A's income tax liability, for example, by preparing and filing the appropriate income tax returns for Year 1 and Year 2 and by making A's books and records available to the examiner. A did not present evidence that intervening events beyond A's control prevented A from filing a return, and there were no other mitigating factors. A has not met the standard described in paragraph (b)(2) of this section for waiver of any applicable filing deadlines in paragraph (b)(1) of this section.

A began a U.S. trade or business in Year 1 as a sole proprietorship. A's tax advisor filed the appropriate U.S. income tax returns for Year 1 through Year 6, reporting income effectively connected with A's U.S. trade or business. In Year 7, A replaced this tax advisor with a tax advisor unfamiliar with U.S. tax law. A did not file a U.S. income tax return for any year from Year 7 through Year 10, although A had effectively connected income for those years. A was aware of A's ability to file a protective return for those years. In Year 11, an Internal Revenue Service examiner contacted A and asked for an explanation of A's failure to file income tax returns after Year 6. A immediately engaged a U.S. tax advisor and cooperated with the Internal Revenue Service in determining A's income tax liability, for example, by preparing and filing the appropriate income tax returns for Year 7 through Year 10 and by making A's books and records available to the examiner. A did not present evidence that intervening events beyond A's control prevented A from filing a return, and there were no other mitigating factors. A has not met the standard described in paragraph (b)(2) of this section for waiver of any applicable filing deadlines in paragraph (b)(1) of this section.
