Summary (TL;DR)
A disregarded entity (DE) is a business entity that the IRS treats as if it does not exist separately from its owner for federal income tax purposes. The most common form is the single-member limited liability company (SMLLC). By default, any LLC with only one member is classified as a disregarded entity unless it elects to be taxed as a corporation by filing Form 8832. The LLC's income, deductions, gains, losses, and credits flow through to the owner's individual tax return, reported on Schedule C. The LLC does not file a separate federal income tax return. However, despite being disregarded for income tax purposes, it remains a separate entity for employment tax and certain excise taxes, and retains its state-level legal liability protection. The disregarded entity classification simplifies tax compliance but is not optimal for all circumstances, particularly those involving significant self-employment tax exposure or plans for equity investment.
What Is a Disregarded Entity?
A disregarded entity is a business entity that the Internal Revenue Service does not recognise as a separate taxable entity from its owner for the purposes of federal income taxation. The term means the IRS "disregards" the entity as being distinct from the person or corporation that owns it. As a result, the business's income, expenses, and tax attributes are treated as belonging directly to the owner and are reported on the owner's own federal income tax return without filing a separate business return at the federal level.
The most common and practically significant type of disregarded entity is the single-member limited liability company (SMLLC). Other types include qualified subchapter S subsidiaries (QSubs), qualified REIT subsidiaries, and in some community property states, a husband-and-wife owned LLC treated as a disregarded entity. This guide focuses primarily on the SMLLC, which is the structure most commonly encountered by small business owners and entrepreneurs.
How the IRS Classifies LLCs
The IRS classifies LLCs under the "check-the-box" regulations in Treasury Regulation Section 301.7701-3. Under these rules, the default classification depends on the number of members: an LLC with only one member is classified as a disregarded entity by default, while an LLC with two or more members is classified as a partnership by default. In either case, the LLC can elect a different classification by filing Form 8832, Entity Classification Election. According to the IRS, for income tax purposes, an LLC with only one member is treated as an entity disregarded as separate from its owner, unless it files Form 8832 and affirmatively elects to be treated as a corporation.
How a Disregarded Entity LLC Is Taxed
For federal income tax purposes, a single-member LLC classified as a disregarded entity is treated as a sole proprietorship if owned by an individual, or as a division of the parent entity if owned by a corporation or partnership. The LLC's income, deductions, and tax credits are reported on the owner's own federal tax return, not on a separate LLC return. Per IRS guidance, a single-member LLC classified as a disregarded entity generally must use the owner's Social Security Number or EIN for all information returns related to income tax.
For an individual owner, business income and expenses are reported on Schedule C of Form 1040. Self-employment income from a disregarded entity LLC is subject to self-employment tax, as the IRS states that the individual owner of a single-member disregarded LLC that operates a trade or business is taxed in the same manner as a sole proprietorship. The self-employment tax rate is 15.3% on net earnings up to the Social Security wage base and 2.9% on amounts above the wage base.
Schedule C Reporting
The owner completes Schedule C (Profit or Loss from Business) as part of their Form 1040, reporting the LLC's gross revenue and deductible business expenses. The net profit or loss from Schedule C flows to the owner's Form 1040 and is included in adjusted gross income. A net profit is also subject to self-employment tax, calculated on Schedule SE. No separate federal business income tax return is required at the entity level.
EIN Requirements
A single-member LLC that is a disregarded entity and has no employees and no excise tax liability does not strictly require an EIN. However, the IRS acknowledges that most new single-member LLCs classified as disregarded entities will need an EIN. An EIN is required if the LLC has any employees, is required to file excise tax forms, or needs one for opening a business bank account. Some payment processors and vendors also require an EIN before processing payments on the LLC's behalf. Applying for an EIN using Form SS-4 is free through the IRS website.
Employment Tax Treatment
Although a disregarded entity SMLLC is ignored for income tax purposes, it is treated as a separate entity for employment tax and certain excise tax purposes. If the LLC has employees, it must use its own name and EIN to report and pay federal employment taxes including income tax withholding, FICA, and FUTA. The IRS specifies that for wages paid after January 1, 2009, the single-member LLC is required to use its name and EIN for reporting and payment of employment taxes.
Advantages of Disregarded Entity Classification
The primary advantage is simplicity of tax compliance. By eliminating the requirement to file a separate federal business tax return, the owner reduces compliance costs, professional fees, and administrative complexity. All business income and expenses are consolidated on the owner's personal return. The disregarded entity also provides pass-through taxation without the corporate double-taxation that applies to C corporations. The LLC retains its state-level liability protection regardless of its federal tax classification, providing limited liability without the administrative burden of a more complex tax structure.
Disadvantages and Limitations
The main disadvantage is full exposure of net business income to self-employment tax. By contrast, an S corporation election allows the owner to pay a reasonable salary subject to payroll taxes and distribute remaining profits as S corporation distributions, which are not subject to self-employment tax. For a business generating significant net income, the payroll tax savings from an S corporation election can exceed the additional compliance costs. A disregarded entity also cannot accommodate additional equity investors without changing its tax classification, as adding a second member automatically converts the LLC from a disregarded entity to a partnership.
Disregarded Entity vs S Corporation vs C Corporation
Disregarded entity classification offers the simplest compliance model and suits early-stage businesses and lower-profit operations. S corporation election offers potential payroll tax savings at higher income levels and is commonly used by profitable single-owner service businesses. C corporation treatment creates a separate taxable entity enabling retained earnings at the corporate rate and is more suitable for venture capital investment, but introduces double taxation on dividends. The optimal choice depends on income level, business growth expectations, investment plans, and the owner's personal tax situation.
How to Change Classification Using Form 8832
An LLC can elect to change its federal tax classification by filing Form 8832 with the IRS. An election can generally take effect no more than 75 days before the filing date and no later than 12 months after. Once an LLC has elected to change its classification, it cannot change again for 60 months from the effective date of the previous election, with limited exceptions. Changing from disregarded entity to corporation triggers deemed tax consequences, including the treatment of the conversion as a contribution of all LLC assets and liabilities to the corporation in exchange for stock.
Multi-Member LLCs and Disregarded Entity Status
A multi-member LLC is not a disregarded entity. By default, an LLC with two or more members is classified as a partnership for federal income tax purposes and must file Form 1065, U.S. Return of Partnership Income. However, special rules apply to a husband-and-wife LLC in a community property state, under which the couple may elect to treat the LLC as a disregarded entity for federal tax purposes.
State Tax Treatment
The federal disregarded entity classification does not automatically determine state tax treatment. Many states follow the federal classification and treat SMLLCs as disregarded entities for state income tax purposes. However, some states impose a separate tax, filing fee, or minimum franchise tax on SMLLCs regardless of federal classification. California, for example, imposes an $800 annual minimum franchise tax on SMLLCs that is not affected by the entity's federal disregarded entity status. Business owners should verify the applicable state tax treatment in each state where they operate.
5 FAQs
What is a disregarded entity LLC?
A disregarded entity LLC is a single-member limited liability company that the IRS treats as inseparable from its owner for federal income tax purposes. The LLC's income, deductions, gains, and losses are reported directly on the owner's personal tax return via Schedule C, and the LLC does not file a separate federal income tax return. Despite being disregarded for income tax purposes, the LLC retains its state-level legal protection and is treated as a separate entity for employment tax and certain excise taxes.
Do disregarded entity LLCs pay self-employment tax?
Yes. An individual owner of a single-member LLC classified as a disregarded entity that operates a trade or business is subject to self-employment tax in the same manner as a sole proprietor. Net business income reported on Schedule C is subject to self-employment tax at 15.3% on net earnings up to the Social Security wage base and 2.9% on amounts above the wage base. This is one reason owners of higher-earning LLCs sometimes elect S corporation status.
Does a disregarded entity LLC need its own EIN?
Not strictly required for income tax purposes, where the owner's own SSN or EIN is used. However, a disregarded entity SMLLC with employees must obtain its own EIN for employment tax reporting. An EIN is also often practically necessary for opening a business bank account and fulfilling state and local tax obligations. Applying for an EIN using Form SS-4 is free and straightforward through the IRS website.
Can a disregarded entity LLC have employees?
Yes. A disregarded entity SMLLC can have employees. For employment tax purposes the LLC is treated as a separate entity from its owner and must use its own name and EIN to report and pay federal employment taxes including withholding, FICA, and FUTA. The LLC must file Form 941 or Form 944 under its own EIN. This treatment has applied since 2009 under IRS regulations.
What is the difference between a disregarded entity and a sole proprietorship?
A sole proprietorship is a business owned and operated by an individual without any separate legal entity. A disregarded entity SMLLC is a separate legal entity created under state law that provides limited liability protection, meaning the owner's personal assets are generally protected from business debts. However, for federal income tax purposes, both are taxed identically: income flows directly to the owner's personal return via Schedule C. The LLC provides legal protection that a sole proprietorship does not, while maintaining the same tax simplicity.
