How to register as self-employed depends almost entirely on two choices: whether you’ll work under your own legal name, and whether you want the liability protection of an LLC. A sole proprietor operating under their own name can start invoicing clients today with no state filing at all. Someone forming an LLC, using a business name, or hiring employees will need to file paperwork, pay a state fee, and get a federal tax ID. Regardless of structure, the IRS expects you to report self-employment income once your net earnings reach $400 for the year and to pay estimated taxes quarterly.1Internal Revenue Service.

Do You Actually Need to Register
If you plan to work as a sole proprietor under your own legal name, you can begin working, invoice clients, and report earnings on your personal tax return without filing anything with the state. The U.S. Small Business Administration confirms that conducting business as yourself under your legal name generally requires no state-level registration.2U.S. Small Business Administration. Register Your Business You and the business are the same legal person. That’s simple, but it also means no protection if the business is sued or takes on debt.
If you want to operate under a name that isn’t your legal name, file a “Doing Business As” (DBA) registration with your county clerk or state government. DBA fees typically run from $10 to $150, and some jurisdictions also require publication in a local newspaper. A DBA doesn’t create a separate legal entity or shield you from liability; it just tells the public who’s behind the name.
The real decision point is whether to stay a sole proprietor or form a limited liability company. That choice drives your paperwork, your personal risk, and how the IRS handles your income.
Choosing a Structure
Sole Proprietorship
The sole proprietorship is the default. No formation filing, no state fee, no annual report. You report business income and expenses on Schedule C attached to your personal Form 1040 and pay self-employment tax on the net profit. The trade-off is unlimited personal liability. If a client sues or a vendor goes unpaid, your personal accounts, car, and home are all reachable.
Single-Member LLC
A single-member LLC puts a legal wall between you and the business. For income tax, the IRS treats it as a “disregarded entity,” so you still file Schedule C the same way a sole proprietor does.3Internal Revenue Service. Single Member Limited Liability Companies For liability purposes, though, the LLC is its own legal person. Business debts and lawsuits generally can’t reach your personal assets, provided you keep the business genuinely separate from your personal finances.
That last condition matters. Courts can disregard an LLC’s liability protection if you commingle personal and business funds, underfund the business, or use the entity mainly to dodge obligations. A dedicated business bank account, clean records, and an operating agreement all reinforce the separation. Some states require single-member LLCs to have an operating agreement; even where it’s optional, the document strengthens your position if the LLC’s independence is ever challenged.
S-Corp Tax Election
An LLC can elect to be taxed as an S corporation by filing Form 8832 or Form 2553 with the IRS. Only the salary you pay yourself would then be subject to the 15.3% self-employment tax; remaining profits pass through as distributions that avoid it. The costs are added payroll complexity, mandatory reasonable compensation, and more filings. It’s worth modeling with a tax professional once your net income is consistently well above the cost of running payroll.
Filing LLC Formation Documents With Your State
If you’re forming an LLC, you’ll file with your state’s Secretary of State office or its equivalent. The core document is usually called Articles of Organization or a Certificate of Formation. It lists your LLC’s name, principal address, registered agent, and members or managers.
Name Search
Run a name availability search in your state’s business database before filing anything. Your name can’t be identical or confusingly similar to an existing registered entity. Most states also restrict words like “bank,” “insurance,” or “university” unless you hold the relevant license. Rejected filings usually mean lost filing fees, so confirm availability first.
Registered Agent
Every LLC must designate a registered agent to accept legal documents on the business’s behalf. The agent needs a physical street address in the state of registration; a P.O. box won’t work. You can serve as your own agent, or hire a commercial service, which typically runs $50 to $300 per year.
Fees and Timeline
LLC formation fees vary by state, generally $50 to $500. Most states accept online filings and process them within a few business days. Mailed applications can take several weeks. Once approved, the state issues a Certificate of Organization or similar document confirming the LLC exists. Keep it. You’ll need it to open a business bank account and set up vendor accounts.
Getting an EIN From the IRS
An Employer Identification Number is a nine-digit federal tax ID. You need one if you form an LLC, hire employees, or open most business bank accounts. Even sole proprietors who could technically use their Social Security number often get an EIN to keep personal information off invoices and W-9 forms.4Internal Revenue Service. Employer Identification Number
The fastest route is the IRS online application, which is free and issues your EIN immediately upon approval. Complete it in a single session; the tool times out after 15 minutes of inactivity.5Internal Revenue Service. Get an Employer Identification Number You can also fax or mail Form SS-4, but expect a wait of several weeks.6Internal Revenue Service. About Form SS-4, Application for Employer Identification Number (EIN) The application asks for the name and Social Security number of the “responsible party” who controls the entity, the reason for applying, and the business’s primary activity.
Watch for third-party sites that charge fees to submit EIN applications for you. The IRS does not charge for an EIN. If a site is asking for payment, you’re not on irs.gov.
Local Licenses and Permits
Federal and state registration is only part of what may apply to you. Many cities and counties require a local business license or tax receipt before you can operate within their jurisdiction. Fees vary widely; some localities charge a flat annual amount, others base it on projected gross receipts.
Home Occupation Permit
Working from home may require a home occupation permit under local zoning. These permits typically limit client visits, prohibit exterior signage, ban visible storage of commercial materials, and restrict noise. For most digital work like consulting or web development the restrictions are rarely a practical problem, but skipping the permit where it’s required can bring fines or a cease-and-desist order.
Professional Licenses
Certain professions require a state-issued license regardless of business structure. Healthcare providers, contractors, accountants, real estate agents, and cosmetologists are common examples, with the specific list set by each state. Licensing boards set their own credentialing, examination, continuing education, and renewal requirements. Start early. Some licenses take months, and working without one can bring civil penalties or criminal charges.
Sales Tax Registration
If you sell taxable goods or certain services, you may need to register for a sales tax permit. Most states issue these for free or a small fee. Once you sell across state lines at volume, economic nexus rules can require you to collect sales tax in states where you have no physical presence, typically triggered around $100,000 in annual sales into that state. This mostly affects product-based businesses, but it’s worth knowing before revenue grows.
Federal Tax Obligations for the Self-Employed
This is where new self-employed workers most often get caught out. Without an employer withholding taxes and paying half of Social Security and Medicare, all of it is on you, and the IRS expects payment throughout the year rather than in a single April check.
The $400 Filing Threshold
You must file a federal income tax return and pay self-employment tax if your net earnings from self-employment reach $400 or more for the year.1Internal Revenue Service. Self-Employed Individuals Tax Center Report income and expenses on Schedule C (Profit or Loss from Business) and calculate self-employment tax on Schedule SE, both attached to your Form 1040.
Self-Employment Tax
Self-employment tax covers Social Security and Medicare. The combined rate is 15.3% on net self-employment earnings: 12.4% for Social Security and 2.9% for Medicare.7GovInfo. 26 USC 1401 – Rate of Tax The Social Security portion applies only up to $184,500 in net earnings for 2026; Medicare has no cap.8Social Security Administration. Contribution and Benefit Base Higher earners pay an additional 0.9% Medicare surtax above $200,000 (or $250,000 if married filing jointly). You can deduct half of your self-employment tax when calculating adjusted gross income, which reduces your income tax bill even though it doesn’t reduce the self-employment tax itself.9Internal Revenue Service. Topic No. 554, Self-Employment Tax
Quarterly Estimated Payments
Because no employer withholds from your income, you’re expected to make quarterly estimated payments using Form 1040-ES. The four deadlines for the 2026 tax year are:10Internal Revenue Service. Estimated Tax
- April 15, 2026, covering January through March
- June 15, 2026, covering April and May
- September 15, 2026, covering June through August
- January 15, 2027, covering September through December
Missing a deadline triggers an underpayment penalty based on how much you owe and how late the payment was. You can generally avoid it if your total tax due at filing is under $1,000, or if you’ve paid at least 90% of the current year’s tax liability or 100% of last year’s total tax, whichever is less. If your adjusted gross income exceeded $150,000 in the prior year, that 100% figure rises to 110%.11Internal Revenue Service. Underpayment of Estimated Tax by Individuals Penalty
The QBI Deduction Has Expired
Through 2025, many self-employed taxpayers could deduct up to 20% of qualified business income under Section 199A. That deduction was available for tax years ending on or before December 31, 2025, and it has not been renewed for 2026.12Internal Revenue Service. Qualified Business Income Deduction Don’t build financial projections around it unless Congress reinstates the provision.
Opening a Business Bank Account
Keeping business and personal finances separate protects your LLC’s liability shield and makes tax time far less painful. Banks are required to verify your business identity before opening a commercial account. What you’ll need:
- Sole proprietors: your EIN (or SSN if you don’t have one), a government-issued photo ID, and a DBA certificate if you’re operating under a name that doesn’t include your legal surname.
- LLCs: your EIN, Articles of Organization or Certificate of Formation, your operating agreement (some banks ask for it), and a government-issued photo ID for each member.
Some banks will also ask for a business license or proof of your physical address, so bring one if you have it.
Business Insurance
Registration and an LLC give you legal standing and some liability protection. Insurance is what keeps a single bad event from wiping you out. Two policies matter for most self-employed workers:
- General liability insurance covers claims of bodily injury, property damage, or reputational harm connected to your business. If a client trips in your office, this is the policy that responds.
- Professional liability insurance, also called errors and omissions, covers claims that your professional work caused a client financial harm through missed deadlines, bad advice, or negligent errors. If you provide expert services for a fee, it fills a gap general liability doesn’t cover.
Workers’ compensation is generally not required if you have no employees, though rules vary by state and some clients or contracts may require you to carry it. Costs depend on industry, revenue, and claims history, but many solo consultants and freelancers can find adequate coverage for a few hundred dollars a year.
Staying Compliant After You Register
Registration isn’t a one-time event. Most states require LLCs to file an annual or biennial report confirming current information like address, registered agent, and members. Fees range from nothing in a handful of states to several hundred dollars, with most under $100. Missing the filing deadline can bring late fees, loss of good-standing status, or administrative dissolution of the LLC, any of which can block you from signing contracts or renewing licenses.
Keep formation documents, your EIN confirmation letter, your operating agreement, and annual report receipts together. You’ll reach for them more often than expected: applying for business credit, onboarding with a new client platform, renewing professional licenses, or responding to a state notice. The administrative side of self-employment isn’t glamorous, but neglecting it quietly erodes the protections and tax benefits you set up in the first place.
