Historically, the IRS has said that a disregarded entity could (and maybe should) use the owner’s taxpayer identification number for income and other tax purposes. For employment tax reporting, the IRS issued Notice 99-6, 1999-1 CB 321 , which said that employment taxes for employees of a disregarded entity could be reported by a disregarded entity in one of two ways:
(1) Calculation, reporting, and payment of all employment tax obligations with respect to employees of a disregarded entity by its owner (as though the employees of the disregarded entity are employed directly by the owner) and under the owner’s name and taxpayer identification number; or
(2) Separate calculation, reporting, and payment of all employment tax obligations by each state law entity with respect to its employees under its own name and taxpayer identification number.
Beginning next year, disregarded entities with employees must have their own employer identification numbers (EIN’s) for employment tax purposes. The IRS has issued final regulations providing that for wages paid on or after Jan. 1, 2009, a disregarded entity is treated as a separate entity for purposes of employment taxes and related reporting requirements. Under the final regulations, the separate entity is treated as a corporation for purposes of employment taxes and related reporting requirements. (The regs also treat disregarded entities as separate entities for certain excise taxes, effective for liabilities imposed and actions first required or permitted in periods beginning on or after Jan. 1, 2008). ( Reg. § 1.1361-4(a)(7) , Reg. § 301.7701-2(c)(2) ) . Under the final regulations, an owner of a disregarded entity treated as a sole proprietorship is subject to self-employment taxes. ( Reg. § 301.7701-2(c)(2) ) .
The regulations provide the following example:
(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).”
These regulations do not change the fact that a disregarded entity will continue to be disregarded for other Federal tax purposes.
