How Are LLCs Taxed?
An LLC does not have one automatic federal tax rate. For federal income tax, a domestic single-member LLC is generally disregarded and a domestic multi-member LLC is generally taxed as a partnership unless the LLC elects corporate treatment. An eligible LLC can instead elect S corporation or C corporation taxation.
How are LLCs taxed?
By default, the IRS generally treats a domestic LLC with one owner as part of the owner's tax return and a domestic LLC with two or more owners as a partnership. Either can elect corporation taxation. An eligible LLC may elect S corporation status. The LLC's federal classification determines which return is filed and how business income reaches the owner, while state taxes, payroll taxes, sales taxes and other obligations are separate questions.

The 4 Federal Tax Paths for an LLC
People often say an LLC has “four tax classifications.” A more precise way to say it is that a domestic LLC has two common default federal income-tax treatments based on its number of owners, plus the ability to elect corporate treatment. An LLC can therefore commonly appear on a tax return as a disregarded entity, partnership, S corporation or C corporation.
| LLC tax path | How you get it | Main federal return | Where income is generally taxed | SE/payroll issue |
|---|---|---|---|---|
| Single-member / disregarded | Default for one-owner domestic LLC | Usually owner's Form 1040 + Schedule C, E or F | Owner | Active trade/business earnings generally subject to SE tax |
| Partnership | Default for domestic LLC with 2+ members | Form 1065 + Schedule K-1 | Members on allocated pass-through items | SE-tax treatment depends on the member and income type |
| S corporation | Election if eligible, generally Form 2553 | Form 1120-S + Schedule K-1 | Shareholders on pass-through items | Owner-employees generally need reasonable compensation subject to payroll tax |
| C corporation | Entity-classification election, generally Form 8832 | Form 1120 | Corporation; shareholders can also be taxed on dividends | Wages are subject to payroll-tax rules |
1. Single-Member LLC Taxation
A domestic LLC with one owner is generally a disregarded entity for federal income-tax purposes unless it elects corporation treatment. “Disregarded” does not mean the LLC is nonexistent for every legal or tax purpose. It means the LLC is generally not treated as separate from its owner for federal income tax. A single-member LLC is still treated separately for certain employment and excise taxes.
If an individual owns the LLC, the business activity is generally reported on the owner's federal return—commonly Schedule C for a trade or business, Schedule E for certain rental/royalty activity, or Schedule F for farming. The correct schedule depends on what the LLC actually does.
Example: Maya owns 100% of a domestic consulting LLC and has made no corporate tax election. The LLC is generally disregarded for federal income tax. Her consulting revenue and deductible business expenses are generally reported through Schedule C, and the net result flows into her individual federal return.
2. Multi-Member LLC Taxation
A domestic LLC with two or more members is generally classified as a partnership for federal income tax unless it elects corporation treatment. The partnership generally files Form 1065, and each member receives a Schedule K-1 reporting that member's share of income, deductions, credits and other items.
A critical beginner point is that partnership tax is based on allocated taxable items—not simply on how much cash the LLC distributes. A member can potentially owe tax on allocated partnership income even if the LLC retained some of the cash. Operating agreements, basis, distributions, guaranteed payments and member participation can materially affect the result.
Self-employment tax for LLC members is not a one-line rule. General partners' distributive shares of trade/business income and guaranteed payments can be treated differently from passive/investment items, and the application of limited-partner rules to LLC members can be complex. Do not assume every dollar on a partnership K-1 is automatically subject—or automatically exempt—from self-employment tax.
Self-Employment Tax: What the 15.3% Number Really Means
For an individual operating an active trade or business through a default single-member LLC, net earnings from self-employment are generally subject to self-employment tax in the same manner as a sole proprietorship. The commonly quoted 15.3% is the combined base rate: 12.4% Social Security plus 2.9% Medicare. It is not necessarily 15.3% of every dollar of business profit.
For 2026, the maximum net self-employment earnings subject to the Social Security portion is $184,500. Medicare rules do not use that same cap, and an additional 0.9% Medicare tax can apply above statutory thresholds based on wages, self-employment compensation and filing status. The self-employment-tax calculation also uses special rules, including the adjustment applied when figuring net earnings from self-employment.
3. LLC Taxed as an S Corporation
An eligible LLC can elect S corporation tax treatment, generally by filing Form 2553. The IRS states that an LLC making an S election does not need to file Form 8832 first; the S election also causes the entity to be treated as a corporation for federal tax-classification purposes.
An S corporation generally files Form 1120-S and passes tax items through to shareholders on Schedule K-1. A shareholder's share of S corporation net business income generally is not self-employment income. But an owner who performs services for the S corporation generally cannot simply characterize all business profit as distributions to avoid employment taxes. The corporation must pay shareholder-employees reasonable compensation for services before making non-wage distributions.
Why an S election can help: after reasonable wages and other expenses, qualifying pass-through profit may not be subject to self-employment tax in the same way as active Schedule C profit. Why it is not automatically better: payroll, tax preparation, bookkeeping, reasonable-compensation requirements, state taxes/fees, QBI interactions and the owner's facts can reduce or eliminate the benefit.
Form 2553 generally must be filed no later than 2 months and 15 days after the beginning of the tax year the election is intended to take effect, or during the preceding tax year. Late-election relief may be available when requirements are met.

4. LLC Taxed as a C Corporation
An LLC can generally elect to be classified as a corporation by filing Form 8832. If it does not make an S election, the corporation generally files Form 1120. The federal corporate income-tax rate is currently 21% of taxable income.
That 21% rate should not be compared directly with an individual's marginal rate and called “cheaper.” A C corporation is a separate federal income-taxpayer, and shareholders can face a second layer of tax when after-tax corporate earnings are distributed as taxable dividends. On the other hand, retained earnings, employee benefits, ownership/investment plans and other facts can make corporate treatment appropriate in some situations.
Do not elect C corporation treatment just because 21% looks lower. Model both the entity-level tax and the owner's tax consequences, including compensation, dividends, state taxes and how much cash will remain in the business.
The QBI Deduction for LLC Owners in 2026
Many owners of businesses taxed as sole proprietorships/disregarded entities, partnerships and S corporations may qualify for the Section 199A qualified business income (QBI) deduction. It can generally equal up to 20% of qualified business income, subject to taxable-income limits and other restrictions. C corporation income and employee wage income do not qualify as QBI.
For 2026, the IRS lists the Section 199A threshold at $403,500 for married filing jointly, $201,775 for married filing separately, and $201,750 for other returns. The 2026 phase-in ranges extend to $553,500 for joint returns, $276,775 for married filing separately and $276,750 for other returns. Above the applicable thresholds, wage/property limitations and specified-service-trade-or-business rules can reduce or eliminate the deduction.
2026 law update: recent legislation made the QBI deduction permanent. Beginning in 2026, the law also adds a minimum deduction framework for taxpayers with at least $1,000 of qualified business income from an active qualified trade or business, subject to the statutory rules. Do not treat “20% QBI” as an automatic 20% deduction from gross revenue.
LLC Federal Tax Path Finder
This tool identifies the common federal income-tax path and forms to investigate. It intentionally does not estimate “tax savings,” because doing that accurately requires income, deductions, wages, filing status, state taxes, owner eligibility and other facts.
This tool covers common domestic LLC federal tax paths. It cannot determine S-corp eligibility, reasonable compensation, QBI eligibility, partner SE-tax status, foreign-owner reporting, state tax or the lowest-tax election for you.

Do LLC Owners Pay Quarterly Taxes?
An LLC does not automatically create a special “quarterly LLC tax.” Instead, owners may need to make estimated tax payments when withholding and other credits will not cover enough of their expected individual income and self-employment tax. The IRS generally allows required estimated income and self-employment taxes to be paid in quarterly installments, subject to its estimated-tax rules and exceptions.
An S corporation with owner-employees generally handles payroll withholding/deposits for wages, while shareholders may still need estimated payments for pass-through income or other income. C corporations have their own estimated-tax rules.
Federal Tax Classification Is Only Half the Picture
Federal classification does not tell you the LLC's total tax cost. States can impose income taxes, franchise taxes, gross-receipts taxes, annual LLC taxes, minimum taxes or other entity-level charges. A state may also treat an S election differently from the federal government. Sales tax, payroll tax, property tax and industry-specific taxes can apply separately.
Federal questions
Default classification, corporate elections, Form 1040/1065/1120-S/1120, self-employment tax, payroll tax and QBI.
State/local questions
Income/franchise tax, annual LLC tax or fee, S-corp tax, sales tax, payroll obligations, local business tax and filing requirements.
For recurring entity costs, use our LLC annual fees guide and LLC Total Cost Calculator. Those costs should not be confused with federal income tax.
Which LLC Tax Classification Is Best?
There is no universally best classification. The default treatment is often the simplest. S corporation taxation can be worth analyzing when an active business has enough sustainable profit to support reasonable owner compensation and the additional payroll/accounting burden. C corporation taxation may fit businesses with different reinvestment, benefits, ownership or capital strategies. Partnership treatment is the default for many multi-owner LLCs and provides substantial allocation flexibility, but it also brings partnership-tax complexity.
| Situation | Path worth investigating | Main reason | Main caution |
|---|---|---|---|
| New solo business, modest/uncertain profit | Default disregarded treatment | Simple federal reporting | Active net earnings may face SE tax |
| Profitable owner-operated business | S corporation analysis | Potential payroll/SE-tax difference on qualifying profit | Reasonable wages + payroll/admin + state costs |
| Two or more owners | Default partnership treatment | Default federal classification; flexible partnership framework | Complex allocations, basis and SE-tax rules |
| Business retaining capital / special corporate strategy | C corporation analysis | Separate taxpayer; 21% federal corporate rate | Potential second tax layer on dividends |
Avoid fixed “S corp at $X profit” rules. A useful break-even analysis must account for reasonable compensation, payroll taxes, tax-preparation/payroll costs, QBI, retirement/benefit effects, state S-corp taxes or fees, filing status and other income. A single profit threshold is not reliable nationwide.
Common LLC Tax Mistakes
- Thinking “LLC” is a federal tax classification. It is a state-law entity type; federal tax treatment depends on default rules and elections.
- Thinking disregarded means tax-free. Business income is generally reported by the owner even though the LLC itself may not file a separate federal income-tax return.
- Calling every owner draw a deductible expense. Owner distributions/draws generally are not ordinary business deductions merely because cash left the LLC.
- Assuming S corporation status eliminates all payroll tax. Owner-employees generally must receive reasonable compensation for services.
- Applying 15.3% to every dollar without limits. Social Security has an annual earnings cap; Medicare and Additional Medicare Tax have different rules.
- Assuming the QBI deduction is always 20% of profit. It has income limitations, business-type rules and other calculations.
- Ignoring state tax. State entity taxes can materially change whether an election saves money.
- Missing election deadlines. Form 2553 and Form 8832 have effective-date rules; late relief is not something to assume automatically.
