Single-Member LLC Tax Guide
A single-member LLC (SMLLC) is a disregarded entity for federal tax — Schedule C, Schedule SE, just like a sole proprietor. Here is exactly how the SMLLC pays federal, state, and self-employment taxes in 2026.
Quick answer
A single-member LLC files no separate federal return — it is 'disregarded' and reports on the owner's 1040 via Schedule C and Schedule SE. SE tax is 15.3% on 92.35% of net profit. Federal income tax applies at the owner's marginal bracket. State income tax is owed wherever the owner is a resident. State LLC filing fees apply separately (annual report, franchise tax in some states).
The "disregarded entity" rule
The IRS treats single-member LLCs as disregarded for federal income tax. The LLC exists for state and legal purposes; for federal tax it is invisible. The owner files Schedule C for income, Schedule SE for self-employment tax, and includes both on Form 1040. No separate Form 1065 or Form 1120 is required. This default treatment can be changed by filing Form 8832 (elect C-corp) or Form 2553 (elect S-corp).
Step-by-step SMLLC federal tax
| Step | Form / Calculation |
|---|---|
| Report business income and expenses | Schedule C |
| Calculate SE tax on net profit | Schedule SE |
| Deduct half-SE above the line | Schedule 1 line 15 |
| Apply standard or itemized deduction | Schedule A or standard |
| Apply QBI deduction | Form 8995 / 8995-A |
| Calculate federal income tax | 1040 tax tables |
| Pay quarterly estimates | Form 1040-ES or EFTPS |
State considerations
State income tax follows the same disregarded-entity flow in most states — the owner pays state tax on the same Schedule C profit. Some states (California, Texas, Tennessee, others) impose franchise or annual taxes on the LLC itself regardless of income. California's $800 minimum franchise tax is the largest standalone hit; Texas has a no-tax-due margin until ~$1.23M revenue.
EIN and bank account
An SMLLC with no employees technically does not need an EIN for federal tax, but practically: banks require one to open a business account, vendors may require it for 1099 reporting, and it keeps your SSN off your tax-related paperwork. Apply for an EIN free at the IRS website in about 15 minutes.
S-corp election option
An SMLLC can file Form 2553 to elect S-corp tax treatment. Once elected, the LLC files Form 1120-S annually, the owner takes a "reasonable" W-2 salary, and the remaining profit distributed as dividends avoids the 15.3% SE tax. The math works once net SE profit reaches around $60K-$80K — below that, payroll service fees and added complexity offset the savings. See how to lower self-employment tax legally for the trade-off.

Recordkeeping
SMLLC recordkeeping is the same as sole prop plus the state filings: separate business bank account, categorized expense ledger, mileage log, home office documentation, retirement contributions, health insurance premiums, and the LLC's state annual report and any franchise tax filings. Keep the operating agreement and EIN letter in your business records folder.
Common mistakes
Treating the SMLLC like a corporation and trying to file a separate corporate return (it is disregarded by default). Missing state annual report deadlines and getting administratively dissolved. Commingling personal and business funds, weakening the liability protection. Electing S-corp status too early. Forgetting to pay quarterly estimates because "the LLC will sort it out at year end" — it will not; you still owe quarterly.
How this fits into the full tax picture
Federal income tax and the 15.3% self-employment tax are the two halves of the federal freelancer tax bill. Both apply to net Schedule C profit; both can be reduced by legitimate business deductions. State income tax adds on top in 41 states. Quarterly estimated payments cover both federal taxes throughout the year so the April reconciliation is small. The whole system rewards consistent recordkeeping more than any single clever tax strategy — track every legitimate deduction, set aside the right percentage, and pay quarterly through EFTPS automatically. The ranked overview at best tax deductions for 1099 workers shows where the biggest dollars sit; the freelancer tax deductions checklist is the tickable run-through, and what expenses can freelancers write off covers edge cases.
What tax software handles automatically
Most modern tax software — TurboTax Self-Employed, FreeTaxUSA, H&R Block Self-Employed, TaxAct Self-Employed — handles the underlying form mechanics automatically once you indicate self-employment income. You enter income amounts and categorized expenses; the software fills out Schedule C, Schedule SE, Schedule 1, Form 8995 for QBI, and any other forms required. The half-SE deduction flows automatically. Quarterly estimated payment calculations are also automatic once prior-year tax is in. DIY paper filers need to handle each form manually, which is where small errors most often creep in.

Building a year-round tax workflow
The freelancers who feel calm at tax time are the ones who built a simple year-round workflow. The pattern that works for almost everyone: separate business bank account that all client payments hit; weekly 20-minute bookkeeping session that categorizes every expense and reconciles to bank; mileage app running automatically on the phone; folder system for receipts (digital photos count); quarterly review the week before each estimated payment deadline that totals income to-date, recalculates the target safe harbor amount, and submits through EFTPS. None of those steps is hard in isolation; what makes them powerful is that they happen consistently. By the time April rolls around, every number that goes onto Schedule C already exists in your records and the filing session is mostly clicking through screens rather than reconstructing a year.

When professional help is worth it
For straightforward freelance returns — one Schedule C, standard deductions, no entity changes — most freelancers DIY successfully with tax software. Professional help tends to earn its fee in specific situations: S-corp election, multi-state work, large or unusual deductions, an IRS notice you do not understand, or an entity decision you are weighing. The typical fee for a freelance Schedule C return is $300-$800 a year, much of which becomes a Schedule C deduction itself, making the net cost meaningfully lower. Above $100,000 of net SE income, the conversation with a CPA usually pays for itself many times over through better entity structuring and retirement-plan choice. The tactical guidance for reducing SE tax legally is at how to lower self-employment tax legally and the underlying Schedule C math is at Schedule C for freelancers explained and Schedule SE explained for freelancers.
What changes as your income grows
At low income (under about $25K of net SE profit), federal income tax is often zero after the standard deduction and QBI, and SE tax is the only federal bill. At mid income ($50K-$100K), federal income tax kicks in meaningfully on top of SE tax, the half-SE deduction starts to matter, and the QBI deduction becomes a real number. Retirement contributions become powerful levers. At higher income ($100K-$200K+), the conversation widens to S-corp election, defined benefit plans, accountable plans for reimbursements, and larger home office deductions — all worth considering with a CPA. The mechanics of the SE deduction at the heart of this are explained at self-employment tax deduction explained. Above $200K of net profit, professional tax planning usually beats the fee many times over.

The bottom line
A single-member LLC is taxed like a sole proprietor by default — same Schedule C, same SE tax, same quarterly payments. The LLC adds legal liability protection and the option to elect S-corp status. Track expenses, pay quarterly, keep state filings current, and the federal math is straightforward.
