How to register as self-employed in the US (2026 guide)
Registering as self-employed in the US is more decision-heavy than in many countries — sole proprietor or LLC, state registration, EIN. Here's the practical path for most freelancers.
Quick answer
Most US freelancers and self-employed people start as a sole proprietor — no formal federal registration required, you file taxes as part of your personal return (Schedule C). State registration depends on where you live (some states require a 'Doing Business As' filing). Get an EIN (free, takes 5 minutes at irs.gov) instead of using your SSN for client invoices. Consider an LLC ($50–$500 depending on state) once you're earning $40k+ for liability protection.
Step-by-step
- 1
Decide between sole proprietor and LLC
Two paths for most US freelancers. Sole proprietor: no formal federal registration, file taxes on Schedule C as part of your personal return, simple and free to start, but no personal liability protection. LLC: formal state registration ($50–$500 depending on state), file annual reports, choose tax treatment (default is pass-through like sole prop, but you can elect S-Corp later), provides personal liability protection. Start as sole proprietor if you're under $40k revenue and risk-tolerant; move to LLC once revenue and exposure grow.

Pick a business name and check availability
If you're using your own legal name (e.g., 'Jane Smith') for your sole proprietorship, you don't need to register a business name. If you want a trade name (e.g., 'Smith Design Studio'), most states require a 'Doing Business As' (DBA) filing — typically $25–$100 at your county clerk's office. Check name availability via your state's Secretary of State website. For LLCs, the LLC name registration replaces the DBA.

Get an EIN (free, takes 5 minutes)
An EIN (Employer Identification Number) is the IRS equivalent of an SSN for businesses. Free at irs.gov/businesses/small-businesses-self-employed/apply-for-an-employer-identification-number-ein-online — takes 5 minutes online. Why bother as a sole proprietor with no employees? You can use the EIN instead of your SSN on client invoices and tax forms (W-9), keeping your SSN private. Also required if you'll open a business bank account or eventually become an LLC.

Register with your state (varies)
Each state has different rules. Some states (Texas, Florida) require sole proprietors to register if using a DBA but otherwise treat self-employed income like personal income. Others (California, New York) require additional registrations or business licences depending on industry. Check your state's Secretary of State website AND your city/county business licensing requirements. Some cities require a local business licence ($30–$200/year) even for solo home-based businesses.

Understand your tax obligations
Self-employed people pay: income tax on profit (income minus deductible expenses), self-employment tax (15.3% — Social Security and Medicare contributions split between employer and employee, but you pay both as self-employed), and potentially state income tax. Critical: you pay quarterly estimated taxes (April, June, September, January) — not just at year-end. The IRS penalises underpayment via quarterly safe harbour rules. Standard advice: save 25–30% of income for taxes and use QuickBooks Solopreneur or similar to estimate quarterlies.
- 6
Open a separate business bank account
Not legally required for sole proprietors (you can use your personal account), but practically essential. Keeps business and personal transactions clean for tax purposes, simplifies year-end accounts, signals professionalism. For LLCs, a separate account is REQUIRED to maintain the liability protection — mixing personal and LLC funds 'pierces the corporate veil' and exposes you personally. Good options: Bluevine, Mercury, Novo, or business accounts at major banks (Chase, Bank of America, Wells Fargo).

Plan for your first tax season
If you started self-employment partway through the year, you'll file Schedule C with your personal 1040 by April 15 the following year. Track every business expense from day one (deducting them legitimately can reduce your tax bill significantly). Common deductions: home office, mileage, equipment, software subscriptions, professional services. Use Wave (free) or QuickBooks Solopreneur ($20/mo) to track from day one. An accountant for your first year ($200–$500) is worth it to understand your specific deductions.
Tips & best practices
- ▸Start as a sole proprietor and form an LLC later if revenue and liability concerns justify it. Don't over-engineer your business structure in the first 6 months.
- ▸Get the EIN even if you don't strictly need it. It's free, fast, and keeps your SSN off client tax forms.
- ▸Pay quarterly estimated taxes from your first quarter as self-employed. Underpayment penalties are small but annoying; getting in the habit early prevents January tax shock.
Common questions
Do I need to register as a sole proprietor in the US?
+−
Federally, no — sole proprietors don't register with the IRS. You file taxes via Schedule C on your personal return. State and local rules vary: some require a DBA filing if using a trade name; some cities require a business licence. Check your specific state and city.
Should I form an LLC or stay a sole proprietor?
+−
Sole proprietor is simpler and free; LLC adds liability protection at $50–$500 setup and ongoing annual fees. Most freelancers start as sole proprietors and form an LLC once they're earning $40k+ or doing work with real liability exposure (advice, design that affects business decisions, anything physical).
Do I need an EIN as a solo freelancer?
+−
Not strictly required if you have no employees, but strongly recommended. It's free, takes 5 minutes, and keeps your SSN off client W-9 forms. Required if you form an LLC or open a business bank account.
What's the biggest mistake new US freelancers make?
+−
Not paying quarterly estimated taxes. The IRS expects payment as you earn (quarterly), not just at year-end. Underpayment triggers small but annoying penalties. Set up quarterly payments through IRS Direct Pay or your tax software from your first quarter.
