Learn how a single-member LLC is taxed, what disregarded entity means, when corporate elections apply, and what California requires.
A single-member LLC, or SMLLC, is a limited liability company with one owner. For federal income-tax purposes, a domestic SMLLC is generally disregarded as separate from its owner unless it elects corporate classification.
When an individual owns a disregarded SMLLC, the LLC's income and deductions are generally reported as part of the owner's federal return. The correct schedule depends on the activity:
The owner does not generally take a deductible W-2 wage from a disregarded SMLLC. Cash moved from the business account to the owner is usually recorded as an owner draw, not a business expense. The business's taxable result is based on income and allowable expenses, not on how much cash the owner withdraws.
If the owner is a corporation or partnership, the disregarded LLC's activity is generally reflected on that owner entity's return instead.
An eligible SMLLC can generally file Form 8832 to elect classification as a corporation. If eligible, it may elect S corporation status using Form 2553. An S election changes federal tax reporting, payroll responsibilities, and owner-payment treatment; it does not merely add a label.
After an effective S election, the entity generally files Form 1120-S. An owner who performs services as a corporate officer or employee generally needs reasonable W-2 compensation before nonwage distributions are used as a substitute for pay.
If treated as a C corporation, the LLC generally files Form 1120 and the corporation pays federal income tax on its taxable income. Wages and dividends then follow separate rules.
Assume Harbor Books LLC has $150,000 of revenue, $30,000 of ordinary business expenses, and $120,000 of net profit before any owner compensation.
Under default disregarded treatment, the $120,000 generally appears on the owner's Schedule C. A $70,000 transfer to the owner does not reduce Schedule C profit; it is generally an owner draw. The owner may owe income tax and self-employment tax based on applicable calculations.
If a valid S election is in effect, the business generally files Form 1120-S, pays reasonable wages to its working owner through payroll, deducts those wages and employer payroll costs, and reports remaining pass-through items on Schedule K-1. The result cannot be compared accurately by subtracting an arbitrary "salary" from profit. Payroll taxes, unemployment taxes, retirement contributions, health-insurance rules, tax-preparation costs, California entity tax, and reasonable compensation all matter.
A sole proprietorship is a one-owner unincorporated business. A disregarded SMLLC owned by an individual often uses the same federal income-tax schedules, but the legal structure is different. The LLC exists under state law; the sole proprietorship does not create a separate state-law entity.
Federal income-tax similarity therefore does not make the two structures identical. Formation, annual filings, fees, contracts, ownership transfers, legal maintenance, and liability considerations may differ.
A default disregarded LLC may not file a separate federal income-tax return, but its owner reports the activity on the applicable return. The LLC may still need:
After a corporate election, the entity's return changes to Form 1120 or Form 1120-S.
California generally requires an SMLLC organized or doing business in the state to file Form 568. A disregarded SMLLC is still separate for California's annual LLC tax, LLC fee, filing requirement, and certain credit limitations.
The $800 annual LLC tax generally applies until the LLC is properly canceled. An additional fee applies when total California income reaches the applicable threshold. That fee uses a measure resembling gross activity rather than net profit, so a low-margin business can still cross the threshold.
California generally follows the federal income-tax classification, but the owner may also need California adjustments, nonresident filings, withholding, payroll filings, or other state reports.
Admitting a second member can change the default federal classification from disregarded entity to partnership. The effective date, contributions, ownership percentages, operating agreement, capital accounts, EIN use, bookkeeping, and tax filings should be addressed before the admission — not reconstructed at year-end.
Community-property rules can create special treatment for an LLC owned by spouses. Do not assume every husband-and-wife LLC is automatically one owner or automatically a partnership; state law, ownership, elections, and federal rules must be reviewed.
Heath Income Tax can prepare a single-member LLC's federal and California filings, reconcile owner activity, and evaluate the tax and payroll consequences of a possible entity election.
Does a single-member LLC file Schedule C?
Many individual-owned disregarded LLCs with active businesses do, but rental, farming, and owner-entity situations can use different forms.
Can the owner be on payroll?
Not generally under default disregarded treatment. Payroll may apply after corporate treatment is elected or when the LLC has other employees.
Does an SMLLC need an EIN?
It depends on employees, excise-tax filings, banking, elections, and other circumstances. The IRS has specific EIN rules for disregarded entities.
Is Form 568 required when the LLC had no activity?
A California-organized LLC generally continues to have filing and annual-tax obligations until properly canceled, even if it is inactive.
