Key Takeaways

  • The IRS treats LLCs based on their ownership: single-member LLCs are “disregarded entities,” while multi-member LLCs are taxed as partnerships by default.
  • LLCs can elect corporate taxation by filing IRS Form 8832, potentially lowering their tax burden under certain conditions.
  • Members must pay income and self-employment taxes on their share of profits, and quarterly estimated tax payments are often required.
  • LLCs can deduct many business expenses and may qualify for a 20% qualified business income (QBI) deduction.
  • The IRS requires specific forms and compliance steps depending on how the LLC is structured and taxed, including Forms 1065, 1120, Schedule C, and Schedule K-1.

LLC IRS treatment defaults to pass-through taxation like a sole proprietorship or partnership; however, the limited liability company can opt to be treated as a corporation for tax purposes. This means that the LLC's profits and losses are reported on the tax returns of each of its owners (referred to as members). The LLC itself does not pay income tax but may be subject to an annual state tax. 

In addition to this beneficial tax structure, an LLC provides the same limited liability protection as a corporation, which protects personal assets. These advantages have led to the LLC's status as America's most popular business entity.

Single-Member LLC Income Taxes

A single-member LLC is treated as a sole proprietorship by the IRS. The business profits and losses are reported on Schedule C and reported with the 1040 informational return. Even funds that are kept within the LLC must be assigned to a specific member on paper and taxed as income. Single-member LLCs owned by a corporation report income and expenses on IRS Form 1120. 

IRS Treatment of Disregarded Entities

The IRS considers a single-member LLC a “disregarded entity,” meaning the business is not separate from its owner for federal tax purposes. While the LLC itself does not file a separate return, the owner must report all business income, deductions, and credits directly on their personal tax return using Schedule C attached to Form 1040.

Even if the LLC retains profits within the company, the IRS still taxes those earnings as though they were distributed to the owner. This is a crucial point for new LLC owners who assume that undistributed income avoids taxation. Additionally, single-member LLCs owned by other entities (like a corporation or another LLC) must file Form 1120 or the appropriate return for the parent company’s classification.

Multi-Member LLC Income Taxes

LLCs with more than one member are treated as partnerships by the IRS, thus subjecting them to pass-through taxation. The member's profit and loss percentage, known as the distributive share, is established in the operating agreement for the LLC. Individual income tax is then assessed on the entire distributive share, even if some of this money is reinvested in the business. 

Multi-member LLCs must file annual informational returns using IRS Form 1065 and provide each member with his or her individual profit and loss breakdown on Schedule K-1. This is then filed with the member's Form 1040. An LLC can also submit IRS Form 8832 to be taxed as a corporation.

IRS Filing Obligations for Multi-Member LLCs

For IRS purposes, multi-member LLCs are treated as partnerships unless they elect otherwise. This means the LLC itself files an informational return (Form 1065) but does not pay federal income taxes directly. Instead, it issues each member a Schedule K-1, which details their share of profits, losses, deductions, and credits. Members then report this income on their individual tax returns.

It’s important to understand that tax liability occurs whether or not profits are distributed. Members may need to pay taxes on reinvested earnings, so planning for quarterly estimated payments is essential. Additionally, the IRS expects multi-member LLCs to maintain proper records, including an operating agreement that outlines each member’s distributive share and responsibilities.

Electing Corporate Taxation for an LLC

LLCs that plan to retain a substantial portion of earnings within the business may want to consider electing corporate taxation. To do so, simply file IRS Form 8832 and check the box indicating corporate tax treatment. As of 2018, standard (C) corporations are taxed on profits at a flat rate of 21 percent, which is lower than the rate for the top three individual income tax brackets (32 to 37 percent). This may provide an opportunity for LLC owners to save on their taxes. However, corporate profits are first taxed at the corporate rate of 21 percent when they are earned and again at capital gains rates of up to 23.8 percent when distributed to shareholders. Retained corporate earnings and fringe benefits, stock ownership plans, and stock options are not subject to double taxes. 

If you decide to elect corporate taxation for your LLC, you must maintain corporate status with the IRS for five years. The IRS will treat your business as a separate entity for tax purposes and hold it responsible for submitting Form 1120 and paying income tax each year. You and the other LLC members are not personally responsible if the business fails to file taxes. 

C-Corp vs. S-Corp Tax Election for LLCs

LLCs can choose to be taxed as a corporation by filing Form 8832 (for C-corporation status) or Form 2553 (for S-corporation status, if eligible).

  • C-Corporation Election: Profits are taxed at a flat 21% corporate rate. However, distributions to members are taxed again as dividends (double taxation). Despite this, retaining earnings in the business for growth can make the C-corp structure advantageous for some LLCs.
  • S-Corporation Election: If eligible, an LLC can elect to be taxed as an S-corporation, allowing profits to pass through to owners while potentially reducing self-employment tax liability. Owners who actively work for the business must be paid a “reasonable salary,” which is subject to payroll taxes, but distributions beyond that salary avoid self-employment taxes.

Before electing either option, LLC owners should carefully weigh the pros and cons and consider consulting a tax professional to ensure the structure aligns with their business goals.

Income and Self-Employment Taxes

Every LLC member must set aside enough money to pay income taxes on his or her share of the business profits. Members estimate their owed tax for the year and then make quarterly payments to the state income tax agency and the IRS. These are due in April, June, September, and January.

Because LLC members are not considered employees, they are not subject to FICA (Social Security and Medicare) tax withholdings. Instead, these are paid from the members directly to the IRS as self-employment taxes. An exception may be made for members who have invested money but do not participate in the direct management of the LLC. Self-employment taxes are reported by members on Schedule SE. Members are subject to the business owner self-employment tax rate of 15.3 percent up to an annual cap and then 2.9 percent for income exceeding that cap.

Estimated Taxes and Compliance Requirements

Because LLC members are typically not employees, the IRS requires them to make quarterly estimated tax payments. These payments cover both income tax and self-employment tax obligations. Missing estimated tax deadlines can result in penalties and interest. The due dates are usually:

  • April 15 – 1st quarter
  • June 15 – 2nd quarter
  • September 15 – 3rd quarter
  • January 15 (following year) – 4th quarter

LLCs must also comply with other IRS filing obligations based on their classification. For instance:

  • Single-member LLCs: File Schedule C with Form 1040.
  • Multi-member LLCs: File Form 1065 and issue Schedule K-1.
  • C-corp elected LLCs: File Form 1120.
  • S-corp elected LLCs: File Form 1120-S and issue Schedule K-1 to shareholders.

Proper recordkeeping and timely filings are crucial to avoid IRS audits or penalties.

Expenses and Deductions

Legitimate business expenses can be deducted from your business income on your tax return, which can substantially decrease your taxable income. Examples of these expenses include car and travel expenses, start-up costs, advertising and marketing costs, and equipment. Beginning in 2018, owners of LLCs and other pass-through entities are eligible for a tax deduction of up to 20 percent of their net income. 

Special Tax Deductions and Credits for LLCs

In addition to standard business deductions, LLCs may qualify for several tax-saving opportunities:

  • Qualified Business Income (QBI) Deduction: Many LLC owners can deduct up to 20% of their qualified business income under Section 199A. This deduction is available to pass-through entities and can significantly lower overall tax liability.
  • Start-Up and Organizational Costs: The IRS allows businesses to deduct up to $5,000 in start-up costs and $5,000 in organizational costs in their first year, with the remainder amortized over 15 years.
  • Retirement Contributions: Contributions to SEP-IRAs, SIMPLE IRAs, or solo 401(k) plans can be deducted, helping reduce taxable income.
  • Health Insurance Premiums: If eligible, members may deduct premiums for health, dental, and long-term care insurance.

Careful tax planning ensures LLCs maximize deductions while staying compliant with IRS regulations.
