LLC Pass-Through Taxation
An LLC is a state-law entity, not a single federal tax category. A domestic one-member LLC is generally disregarded for federal income tax by default, while a domestic LLC with two or more members is generally taxed as a partnership unless a valid election changes the classification.
What is LLC pass-through taxation?
Pass-through taxation means eligible business income, deductions, gains, losses and other federal tax items generally reach the LLC's owner or members rather than being taxed under the regular C-corporation income-tax system at the entity level. The reporting form, self-employment/payroll tax treatment, QBI deduction and state tax still depend on the classification and facts.
Pass-Through Does Not Mean “Tax-Free”
The key benefit of pass-through treatment is structural: the business's federal income-tax items generally flow to its owner or members instead of first being taxed under the regular C-corporation regime. But that does not eliminate owner-level federal income tax, self-employment or payroll tax, state tax, or LLC-specific state fees.
Use this order: classify the LLC first → identify the federal reporting form → calculate owner-level employment/self-employment tax → test Section 199A/QBI → add state treatment.
Default Federal Tax Classifications
A domestic single-member LLC is generally disregarded for federal income tax unless another classification is elected.
A domestic multi-member LLC is generally treated as a partnership unless it elects corporate classification.
An eligible LLC can change its federal tax treatment through a valid election while remaining an LLC under state law.
Community-property exception: certain husband-and-wife LLCs in community-property situations can qualify for special federal treatment. Do not apply that exception to married owners generally.
Single-Member LLC Pass-Through Treatment
For federal income tax, an individually owned domestic single-member LLC is generally disregarded unless it elects corporate treatment. The business activity is reported on the owner's return using the schedule appropriate to the activity—for example, Schedule C for many active businesses, Schedule E for many rental activities, or Schedule F for farming.
The LLC can still be treated separately for certain federal employment and excise-tax purposes, so “disregarded” does not mean the LLC is invisible for every federal tax rule.
Multi-Member LLC Pass-Through Treatment
A domestic LLC with two or more members is generally classified as a partnership unless it elects corporate treatment. The partnership generally files Form 1065 and passes each member's allocable tax items through on Schedule K-1.
A K-1 is not necessarily a cash payment. A member can be allocated taxable income even when the LLC retains cash. Multi-member agreements therefore often address distributions intended to help members cover tax liabilities, subject to the agreement and applicable law.
Self-Employment Tax Is Not One Blanket LLC Rule
An individual owner of a disregarded LLC operating an active trade or business generally computes self-employment tax in the same manner as a sole proprietor. Partnership-taxed LLCs are more nuanced: the treatment of a member's distributive share and guaranteed payments can depend on the member's status, services and the underlying activity.
| Owner situation | General federal direction |
|---|---|
| Individual owner · disregarded active trade/business | Net earnings are generally subject to self-employment-tax rules. |
| Partnership-taxed LLC member | Self-employment treatment depends on member status, services and the nature of the income. |
| S-corporation shareholder-employee | Reasonable W-2 wages are subject to employment-tax rules; non-wage distributions are treated separately. |
| Traditional rental real estate | Different rules can apply; rental income is not automatically treated like active Schedule C earnings. |
For 2026, the Social Security wage base is $184,500. The Medicare component uses a different framework and is not capped at that same wage base.
2026 Section 199A / QBI Deduction
Eligible noncorporate owners can potentially deduct up to 20% of qualified business income under Section 199A, but the final deduction can be affected by taxable income, capital gains, specified service trade or business status, W-2 wages, qualified property and other rules.
| 2026 filing status | Threshold | Upper end of phase-in range |
|---|---|---|
| Married filing jointly | $403,500 | $553,500 |
| Married filing separately | $201,775 | $276,775 |
| All other returns | $201,750 | $276,750 |
Do not read “up to 20%” as “20% of LLC profit.” The actual deduction can be lower, and above the threshold a complete Section 199A limitation analysis may be required.
Changing the LLC's Tax Classification
An LLC can elect corporate treatment using Form 8832. An eligible LLC seeking S-corporation taxation can generally use Form 2553 when the S-corporation eligibility requirements are satisfied. These are federal tax elections; they do not convert the state-law LLC into a corporation.
See our IRS Form 8832 Guide and IRS Form 2553 Guide.
S-Corporation Election: No Universal Break-Even
There is no IRS-established $60,000, $80,000 or other universal profit threshold at which an S-corporation election automatically becomes worthwhile. The analysis depends on reasonable compensation, remaining profit, payroll and tax-preparation costs, state taxes, retirement/benefit planning and the owner's facts.
Reasonable compensation matters. A shareholder-employee who performs services cannot simply label all business profit as distributions to avoid employment tax. The salary must be supportable under the facts.
State Pass-Through Entity Tax (PTET)
State PTET regimes are not one national system. Eligibility, rates, election deadlines, estimated payments, owner credits or deductions and entity types can differ substantially by state.
PTET should be modeled, not assumed. An election that is useful for one owner/entity/state combination may not be beneficial for another.
Default Pass-Through vs. C-Corporation Treatment
| Issue | Default pass-through LLC | LLC taxed as C corporation |
|---|---|---|
| Federal entity-level income tax | Generally no regular federal corporate income tax under disregarded/partnership default. | Corporation is a separate federal income-tax taxpayer. |
| Owner reporting | Tax items generally reach owner/member returns. | Owners generally report shareholder-level items such as wages or dividends. |
| QBI deduction | Potentially available to eligible noncorporate owners, subject to limits. | Not available to the C corporation itself. |
| Losses | Can pass through, but basis, at-risk, passive activity and other limits can restrict use. | Corporate losses generally remain at the corporation level. |
LLC Pass-Through Tax Planning Estimator
The original page's calculator concept is preserved, but this version avoids pretending that profit alone can determine an exact QBI deduction.
Below the 2026 threshold
Educational estimate only. SE tax assumes no other wages and models 92.35% of profit, 12.4% Social Security up to the 2026 $184,500 wage base, plus 2.9% Medicare. Additional Medicare Tax is not modeled. The QBI figure is only a simple ceiling and excludes capital-gain adjustments, SSTB, W-2 wage/property limits and other Section 199A rules.
