US LLC Tax Treatment Guide & Rate Reference (2025)

How LLCs are Taxed by the IRS

A Limited Liability Company (LLC) is a state legal entity, but the IRS taxes it based on its chosen classification. An LLC can be taxed in one of several ways:

  • Disregarded Entity: A single-member LLC (an LLC with only one owner) is automatically taxed as a Sole Proprietorship unless it elects otherwise. The LLC's income and expenses are reported on the owner's personal tax return (Form 1040, Schedule C).
  • Partnership: A multi-member LLC (an LLC with two or more owners) is automatically taxed as a Partnership unless it elects otherwise. The LLC files an information return (Form 1065), and each owner receives a Schedule K-1 showing their share of the income/loss, which they report on their personal tax return.
  • S-Corporation: An LLC can elect to be taxed as an S-Corporation by filing Form 2553. Like Partnerships, income/loss is passed through to owners, but S-Corp owners who work for the business are often treated as employees, receiving a salary subject to payroll taxes. Remaining profits can be distributed without being subject to Self-Employment tax.
  • C-Corporation: An LLC can elect to be taxed as a C-Corporation by filing Form 8832. The LLC is then taxed as a separate entity on its profits (Form 1120) at corporate income tax rates.

The applicable tax rates depend entirely on which of these classifications your LLC uses for federal income tax purposes.

This guide provides information on U.S. federal income tax rates for the 2025 tax year based on your LLC's classification. State tax rules also apply and vary.

Select how your LLC is taxed for U.S. federal income tax purposes. If you have a multi-member LLC and have not filed an election (Form 2553 or 8832), your default classification is Partnership. If you have a single-member LLC and have not filed an election, your default is Disregarded Entity (taxed as a Sole Proprietor).

Selecting your classification here will show the relevant federal income tax rates in the next tab.

Select your LLC's federal tax classification in the previous tab to see the applicable tax rates for the 2025 tax year.

Remember that state income tax rates also apply and vary significantly.

Understanding the tax implications for a Limited Liability Company (LLC) in the USA can be complex due to its flexible nature. Our free US LLC Tax Treatment Guide & Rate Reference simplifies these complexities, providing clear, actionable information for business owners and aspiring entrepreneurs. This comprehensive resource helps you decipher how your LLC will be taxed by the IRS and relevant state authorities.

Unlike corporations, an LLC itself is not recognized as a separate tax entity by the IRS by default. Instead, it offers “pass-through” taxation, meaning profits and losses are passed through to the owners’ personal tax returns. This guide details the common default tax classifications:

  • Single-Member LLCs: By default, these are treated as sole proprietorships. The owner reports all business income and expenses on Schedule C (Form 1040) of their personal tax return, and is subject to individual income tax rates and self-employment taxes (Social Security and Medicare).

  • Multi-Member LLCs: By default, these are treated as partnerships. The LLC files an informational return (Form 1065) and issues a Schedule K-1 to each member, detailing their share of income, deductions, and credits. Each member then reports this on their personal tax return and pays individual income tax and self-employment taxes.

Crucially, LLCs have the flexibility to elect to be taxed as an S Corporation or a C Corporation. Our guide explains the implications of these elections, including how S Corp status can potentially reduce self-employment taxes for owners who take a reasonable salary, and how C Corp taxation involves entity-level corporate tax (currently a flat 21% federal rate) plus individual taxation on dividends (known as “double taxation”).

You’ll also find a reference to general federal income tax rates that apply to individuals (relevant for pass-through LLCs) and the corporate tax rate. While state tax rates vary widely, this guide provides a foundational understanding of what to expect, encouraging you to consult state-specific resources. Equip yourself with the knowledge to make informed tax decisions for your US LLC and ensure compliance with federal and state regulations.
