§ 301.7701-2. Business entities; definitions.

In 2006, X, a domestic corporation that reports its taxes on a calendar year basis, merges into Z, a domestic LLC wholly owned by Y that is disregarded as an entity separate from Y, in a state law merger. X was not a member of a consolidated group at any time during its taxable year ending in December 2005. Under the applicable state law, Z is the successor to X and is liable for all of X's debts. In 2009, the Internal Revenue Service (IRS) seeks to extend the period of limitations on assessment for X's 2005 taxable year. Because Z is the successor to X and is liable for X's 2005 taxes that remain unpaid, Z is the proper party to sign the consent to extend the period of limitations.

The facts are the same as in Example 1, except that in 2007, the IRS determines that X miscalculated and underreported its income tax liability for 2005. Because Z is the successor to X and is liable for X's 2005 taxes that remain unpaid, the deficiency may be assessed against Z and, in the event that Z fails to pay the liability after notice and demand, a general tax lien will arise against all of Z's property and rights to property.

(i) LLCA is an eligible entity owned by individual A and is generally disregarded as an entity separate from its owner for Federal tax purposes. However, LLCA is treated as an entity separate from its owner for purposes of subtitle C of the Internal Revenue Code. LLCA has employees and pays wages as defined in sections 3121(a), 3306(b), and 3401(a).

(ii) LLCA is subject to the provisions of subtitle C of the Internal Revenue Code and related provisions under 26 CFR subchapter C, Employment Taxes and Collection of Income Tax at Source, parts 31 through 39. Accordingly, LLCA is required to perform such acts as are required of an employer under those provisions of the Internal Revenue Code and regulations thereunder that apply. All provisions of law (including penalties) and the regulations prescribed in pursuance of law applicable to employers in respect of such acts are applicable to LLCA. Thus, for example, LLCA is liable for income tax withholding, Federal Insurance Contributions Act (FICA) taxes, and Federal Unemployment Tax Act (FUTA) taxes. See sections 3402 and 3403 (relating to income tax withholding); 3102(b) and 3111 (relating to FICA taxes), and 3301 (relating to FUTA taxes). In addition, LLCA must file under its name and EIN the applicable Forms in the 94X series, for example, Form 941, “Employer's Quarterly Employment Tax Return,” Form 940, “Employer's Annual Federal Unemployment Tax Return;” file with the Social Security Administration and furnish to LLCA's employees statements on Forms W-2, “Wage and Tax Statement;” and make timely employment tax deposits. See §§ 31.6011(a)-1, 31.6011(a)-3, 31.6051-1, 31.6051-2, and 31.6302-1 of this chapter.

(iii) A is self-employed for purposes of subtitle A, chapter 2, Tax on Self-Employment Income, of the Internal Revenue Code. Thus, A is subject to tax under section 1401 on A's net earnings from self-employment with respect to LLCA's activities. A is not an employee of LLCA for purposes of subtitle C of the Internal Revenue Code. Because LLCA is treated as a sole proprietorship of A for income tax purposes, A is entitled to deduct trade or business expenses paid or incurred with respect to activities carried on through LLCA, including the employer's share of employment taxes imposed under sections 3111 and 3301, on A's Form 1040, Schedule C, “Profit or Loss for Business (Sole Proprietorship).”

(i) LLCB is an eligible entity that has a single owner, B. LLCB is generally disregarded as an entity separate from its owner. However, under paragraph (c)(2)(v) of this section, LLCB is treated as an entity separate from its owner for certain purposes relating to excise taxes.

(ii) LLCB mines coal from a coal mine located in the United States. Section 4121 of chapter 32 of the Internal Revenue Code imposes a tax on the producer's sale of such coal. Section 48.4121-1(a) of this chapter defines a “producer” generally as the person in whom is vested ownership of the coal under state law immediately after the coal is severed from the ground. LLCB is the person that owns the coal under state law immediately after it is severed from the ground. Under paragraph (c)(2)(v)(A)(1) of this section, LLCB is the producer of the coal and is liable for tax on its sale of such coal under chapter 32 of the Internal Revenue Code. LLCB must report and pay tax on Form 720, “Quarterly Federal Excise Tax Return,” under its own name and taxpayer identification number.

(iii) LLCB uses undyed diesel fuel in an earthmover that is not registered or required to be registered for highway use. Such use is an off-highway business use of the fuel. Under section 6427(l), the ultimate purchaser is allowed to claim an income tax credit or payment related to the tax imposed on diesel fuel used in an off-highway business use. Under paragraph (c)(2)(v) of this section, for purposes of the credit or payment allowed under section 6427(l), LLCB is the person that could claim the amount on its Form 720 or on a Form 8849, “Claim for Refund of Excise Taxes.” Alternatively, if LLCB did not claim a payment during the time prescribed in section 6427(i)(2) for making a claim under section 6427, § 1.34-1 of this chapter provides that B, the owner of LLCB, could claim the income tax credit allowed under section 34 for the nontaxable use of diesel fuel by LLCB.

(iv) Assume the same facts as in paragraph (c)(2)(v)(C) Example (i) and (ii) of this section. If LLCB does not pay the tax on its sale of coal under chapter 32 of the Internal Revenue Code, any notice of lien the Internal Revenue Service files will be filed as if LLCB were a corporation.
