LLC basics for a solopreneur: a limited liability company is a state-law entity that can separate most business debts from your house, car, and savings. It is not a tax category. A one-owner LLC on the default setting is taxed like a sole proprietorship. Fees, annual bills, and any ownership filing depend on the state.
If you run that company with no employees, you are a solopreneur. A freestyle entrepreneur builds the business around a life, so the entity has to be one you can keep up with on a Tuesday night, not a stack of corporate minutes. The rest of this cluster sits on Start & Run a Solopreneur Business.
US federal rules, plus California, Delaware, and New York examples fetched November 2, 2026. General information, not legal, tax, or insurance advice. State rules differ. Check yours, and ask a lawyer or a CPA before you file.
What an LLC is
The IRS calls a limited liability company “an entity created by state statute” and tells you to check that state before you start one. You file with a state office, name a registered agent who is located in that state, and the state treats the company as separate from you. The U.S. Small Business Administration’s launch page, fetched November 2, 2026, says “LLCs protect you from personal liability in most instances, your personal assets — like your vehicle, house, and savings accounts — won’t be at risk in case your LLC faces bankruptcy or lawsuits.”
Hold the word “most.” The same page says an LLC or a corporation “can protect your personal property from lawsuits. However, that protection has limits.” When a member joins or leaves, the SBA says “some states may require the LLC to be dissolved and re-formed with new membership — unless there’s already an agreement in place within the LLC for buying, selling, and transferring ownership.” The SBA’s line on the agreement is: “It’s widely recommended to create one to protect yourself and your business, even if your state doesn’t mandate it.” New York does require a written one. The deadline is in the cost section.
How the IRS taxes a one-owner LLC
The IRS LLC page, fetched November 2, 2026, says a domestic LLC with two or more members is a partnership unless it files Form 8832 and elects to be a corporation. “For income tax purposes, an LLC with only one member is treated as an entity disregarded as separate from its owner, unless it files Form 8832 and elects to be treated as a corporation.”
Skip the corporate election and the activity goes on Form 1040 or 1040-SR, Schedule C, E, or F. “An individual owner of a single-member LLC that operates a trade or business is subject to the tax on net earnings from self employment in the same manner as a sole proprietorship.” The legal box changed. The tax bill did not. Legal cuts, once a CPA is in the room, are in avoiding the taxman. For employment tax and certain excise taxes the LLC “is still considered a separate entity,” and wages paid after January 1, 2009 use its own name and EIN. For income tax you generally use your Social Security number or EIN. Get an EIN on Form SS-4 if a bank or your state asks. With no employees and no excise tax, the IRS says you do not need one for federal tax.
A spouse is not automatically the same owner. Under Rev. Proc. 2002-69, the IRS will accept either disregarded-entity or partnership treatment for a qualified entity owned only by husband and wife as community property. “If an LLC is owned by husband and wife in a non-community property state, the LLC should file as a partnership.” The day-to-day version of that choice is in working with your spouse.
What the shield covers
Say you run a design studio of one and a client sues over a failed project. If the claim is against the company, the LLC’s assets are the main target, not the house. That is a hypothetical, not a client of this site.
Where the shield stops
- Your own wrongdoing. Negligence, fraud, or malpractice you commit can still land on you. The shield is aimed at company debts and other people’s mistakes.
- A promise you sign in your own name. A loan, a lease, or a supplier form that you guarantee is your debt. Lenders to small LLCs ask for that signature constantly. Read the line before you treat the LLC as the borrower.
- Unpaid trust-fund taxes. If you withhold employment taxes and do not deposit them, the Trust Fund Recovery Penalty can follow a person who is responsible for paying them and “willfully fails to collect or pay them,” when the tax “cannot be immediately collected from the business.” “The amount of the penalty is equal to the unpaid balance of the trust fund tax.” That is withheld employee money, not your own income tax. The IRS page was fetched November 2, 2026.
- A company you treat as a personal account. Mixed funds, skipped filings, and a company with no money of its own are how that separation fails in practice. The SBA says business banking “offers limited personal liability protection by keeping your business funds separate from your personal funds.”
Write the operating agreement even as the only member, and keep state filings current. Then buy insurance. The SBA points to general liability for lawsuits and injuries, and professional liability for “malpractice, errors, and negligence.” A filing stamp replaces neither. If the work is still a string of gigs, read solopreneur vs freelancer first.
What it costs, in three states
The SBA says, “In most cases, the total cost to register your business will be less than $300, but fees vary depending on your state and business structure.” That line is the filing, not the yearly bill. These three examples were fetched November 2, 2026. They are not a 50-state price list.
| State | Official figure | What you are paying for |
|---|---|---|
| California | $800 for taxable year 2026 | Annual LLC tax if you are doing business in California or the Secretary of State has accepted the articles or issued a certificate of registration. Due the 15th day of the 4th month (April 15, 2026 for a calendar year), every year until cancellation. Narrow exceptions include certain title-holding companies and, for tax years beginning before January 1, 2030, a deployed service member’s LLC that loses money or stops. |
| Delaware | $400 on the tax instructions; the FAQ still said $300 | The LLC tax instructions say domestic and foreign LLCs pay $400 a year, with no annual report, due on or before June 1. A miss adds a $200 penalty plus 1.5% interest per month, and there is no proration. The tax FAQ on the same site still said $300. The formation cover letter says the certificate fee is $110 and the annual tax is $400. Confirm the amount before you pay. |
| New York | $200 to file; $50 for the publication certificate | Most LLCs must publish for six straight weeks in two newspapers the county clerk names, then file a Certificate of Publication within 120 days or the authority to do business is suspended. The papers set their own fee. A written operating agreement is required before, at, or within 90 days after filing. The state says the law is silent on skipping it. A lawyer is not required. |
If you are active in another state, the SBA says you might need to foreign-qualify, and those businesses “typically need to pay taxes and annual report fees in both” the home state and the other one. Signs include a physical presence, frequent in-person meetings, a significant share of revenue, or an employee working there.
The S corporation election is a second decision
You do not have to form a new corporation to be taxed as an S corporation. The Instructions for Form 2553, revised December 2020 and still the version on IRS.gov on November 2, 2026, say an entity that meets the tests “will be treated as a corporation as of the effective date of the S corporation election and doesn’t need to file Form 8832.” File it “no more than 2 months and 15 days after the beginning of the tax year the election is to take effect,” or during the preceding tax year. Late relief can be available for reasonable cause. The instructions limit who qualifies. Do not assume a late form will be forgiven.
The appeal is wages versus distributions. On the default LLC, net earnings from the trade or business are self-employment income. As an S corporation, the IRS says you “must pay reasonable compensation to a shareholder-employee in return for services that the employee provides to the corporation before non-wage distributions may be made.” It can reclassify distributions as wages, and payments tied to your own services “should be classified as wages that are subject to employment taxes.” A token salary and a large distribution is the pattern that page is written to stop.
Wages mean payroll deposits on top of Form 1120-S. The same instructions cap owners at 100 shareholders (a married couple can count as one), limit them to “individuals, estates, exempt organizations described in section 401(a) or 501(c)(3), or certain trusts,” bar “nonresident alien shareholders” aside from a narrow trust exception, and require one class of stock “disregarding differences in voting rights.” A federal election does not cap California’s $800 or Delaware’s annual tax. The IRS pages fetched here state no dollar line for when to elect. Ask a CPA when profit sits above a reasonable salary for the work you do. If the profit is modest, the extra return can eat the difference.
BOI reporting in 2026
FinCEN’s BOI page, updated August 11, 2026 and fetched November 2, 2026, says “U.S. companies are exempt from the Beneficial Ownership Information (BOI) reporting requirements and therefore, are no longer required to file BOI reports.” The final rule “became effective on August 14, 2026” and made permanent the exemptions in the interim final rule published March 26, 2025. Federal Register document 2026-16576 says the same about domestic reporting companies.
Who still reports is an entity “formed under the law of a foreign country” and registered to do business in a US state or Tribal jurisdiction. A Delaware, California, or New York LLC you form under that state’s law is not that entity. New York’s own page, fetched the same day, applies its disclosure, effective January 1, 2026, only to non-exempt LLCs “formed under the law of a foreign country and which are authorized to do business in New York.” A New York LLC formed under New York law is outside that sentence. State annual reports and franchise taxes still apply. The federal exemption does not cancel them.
FinCEN says “There is NO fee to file BOI directly with FinCEN,” and it does not send letters asking you to pay. A seller pushing a BOI filing for a US-formed LLC in 2026 deserves a look at fincen.gov/boi before you pay.
LLC, sole prop, or corporation
- Sole proprietorship. The SBA says these “do not produce a separate business entity,” so you can be personally liable for the business’s debts. Fine for a low-risk test. A weak box once contracts and real money show up.
- LLC. A separate state-law entity, default pass-through tax, an operating agreement, a registered agent, and a state bill that can arrive in a thin year.
- Corporation. The SBA says corporations offer the strongest protection and require more record-keeping, and that C corporation profits can be taxed at the company and again when paid out. Useful if you truly plan to issue stock. The S election above is available to a qualifying LLC without that extra shell.
The SBA says an LLC can suit a higher-risk business and an owner who wants “a lower tax rate than they would with a corporation.” That comparison is with a C corporation. It does not lower the tax you already pay as a sole proprietor.
What you decide, what a tool drafts, what you check
In November 2026 a general writing assistant can turn your notes into a question list or a first draft of an operating agreement. It does not know your state’s fee, and it will invent a tax saving if you let it. Do not crown a product. Use this split:
| You decide | A tool drafts | You check |
|---|---|---|
| Formation state, registered agent, and whether you will sign a personal guarantee | A filing checklist from the notes you paste in | The fee, the annual tax, and any publication rule on the state’s own site |
| Whether profit is high enough to ask a CPA about Form 2553 | Questions for that CPA, using a pay range you supply | That nobody files the election until the CPA says the tests fit |
| What the operating agreement must say about a spouse, death, or shutting down | A first draft from those facts | A lawyer reads it before you rely on it. New York’s 90-day clock is yours |
The takeaway
Form an LLC when you sign contracts, hold client work that can go wrong, or want a wall between the business and the household. File it in a state whose annual bill you have actually read. Keep a separate bank account, write the operating agreement, stay current on state filings, and buy insurance that matches the work. Leave the S corporation election for a CPA once profit clears a real salary. If someone says a US-formed LLC must file a federal BOI report in 2026, open FinCEN’s page before you pay them.
