To become an independent contractor, you choose a business structure, register your business name and get a tax identification number, obtain any licenses your work requires, and set up your own tax payments before you take on clients. None of it is complicated on its own, but the order matters, and the tax piece is the part most new contractors underestimate.
Before you file anything, confirm you actually qualify. The IRS decides whether someone is an independent contractor or an employee by looking at behavioral control, financial control, and the type of relationship with the hiring company. The less control the company has over how you do the work, the more likely you are a contractor.1Internal Revenue Service. Independent Contractor (Self-Employed) or Employee? If a client dictates your hours, supplies your tools, and treats you like staff, calling yourself a contractor on paper will not hold up.
Pick a Structure: Sole Proprietor or LLC
Your first real decision is how to operate. For most solo contractors, it comes down to two options.
A sole proprietorship is the default. You and the business are the same legal person, most states let you start working right away without formation paperwork, and you report income on Schedule C of your personal return.2Internal Revenue Service. Instructions for Schedule C (Form 1040) The cost is exposure: your home, savings, and car are on the line for any business debt or lawsuit.
A limited liability company creates a separate legal entity, so your personal assets are generally shielded and your financial exposure is limited to what you have put into the business. You form one by filing Articles of Organization with your state’s secretary of state, usually through an online portal. Filing fees run roughly $50 to $500 depending on the state. A single-member LLC is still treated as a sole proprietorship for federal tax purposes by default, so you file the same Schedule C either way; the difference is liability, not taxes.2Internal Revenue Service. Instructions for Schedule C (Form 1040)
If you go the LLC route, expect to name a registered agent (a person or company with a physical street address in your state who can receive legal notices) and to decide whether the LLC is member-managed or manager-managed. Once processed, you’ll get a certificate of formation. Keep it. Banks, insurers, and clients will ask for it.
Register Your Business Name
If you plan to operate under a name other than your legal name, you file a “Doing Business As” (DBA) statement, sometimes called a fictitious name filing. Where you file and what you pay depends on the jurisdiction; some states route DBAs through the county clerk, others through the secretary of state.
If you form an LLC, the name in your Articles of Organization becomes your official business name automatically. A separate DBA is only needed if you want to operate under an additional name that differs from the registered one.
Get an EIN
An Employer Identification Number is your business’s tax ID. Sole proprietors with no employees can technically use their Social Security number, but you’re required to have an EIN if you have employees, run a partnership or corporation, file certain excise tax returns, or maintain a qualified retirement plan.3Internal Revenue Service. Instructions for Form SS-4 Many sole proprietors get one anyway so they don’t have to hand out their SSN on every W-9. LLCs need one regardless.
The IRS issues EINs for free through an online application that returns your number immediately.4Internal Revenue Service. Get an Employer Identification Number Form SS-4 asks for your entity’s legal name, a responsible party with a Social Security or ITIN number, the business start date, and a description of your principal business activity.5Internal Revenue Service. Form SS-4 You can use the number right away to open a bank account, apply for licenses, and file returns.6Internal Revenue Service. Employer Identification Number
Handle Licenses and Permits
Licensing depends entirely on what you do and where. Some contractors need nothing beyond their business registration. Others face requirements at three levels.
Federal
Most contractors don’t need a federal license. You do if your work touches a federally regulated activity: agriculture involving interstate movement of animals or plants, alcoholic beverages, aviation, firearms and explosives, commercial fishing, maritime transportation, mining and drilling on federal land, nuclear energy, or radio and television broadcasting.7U.S. Small Business Administration. Apply for Licenses and Permits
State
Professional fields including engineering, healthcare, accounting, and legal consulting require an active license from a state board. You’ll typically submit transcripts, exam scores, or verification of an existing license.
Local
If you’re working from home, check whether local zoning allows it. Many municipalities require a home occupation permit that limits client traffic, signage, and how much of your home is used for business. Food service and hazardous materials work often need health department clearances or environmental permits on top of that. Your municipal planning office is the right first call. Operating without required permits can bring fines or an order to stop working.
Set Up Your Taxes Before Your First Invoice
This is the part that trips people up. No client will withhold taxes from what they pay you, so both income tax and self-employment tax are on you, and the IRS expects the money throughout the year, not just at filing time.
Self-Employment Tax
Independent contractors pay a 15.3% self-employment tax on net earnings: 12.4% for Social Security and 2.9% for Medicare. When you’re an employee, the employer covers half. As a contractor you pay the whole thing. The Social Security portion applies to the first $184,500 of net earnings in 2026; Medicare applies to all net earnings with no cap.8Social Security Administration. If You Are Self-Employed You can deduct half of your self-employment tax when calculating adjusted gross income.9Internal Revenue Service. Schedule SE (Form 1040)
Quarterly Estimated Payments
If you expect to owe $1,000 or more when you file, you’re expected to make estimated tax payments four times a year.10Internal Revenue Service. Estimated Taxes For the 2026 tax year the deadlines are:
- First quarter: April 15, 2026
- Second quarter: June 15, 2026
- Third quarter: September 15, 2026
- Fourth quarter: January 15, 2027
You can skip the January 15 payment if you file your full 2026 return and pay the balance by February 1, 2027.11Internal Revenue Service. Form 1040-ES – Estimated Tax for Individuals Missing a payment triggers an underpayment penalty calculated at an interest rate the IRS sets quarterly (7% for early 2026).12Internal Revenue Service. Quarterly Interest Rates
Records
Keep records supporting income, deductions, and credits for at least three years from the date you file. If you underreport income by more than 25%, the window stretches to six years. Employment tax records need to be kept for at least four.13Internal Revenue Service. How Long Should I Keep Records Save invoices, receipts, contracts, and bank statements from day one. It makes filing easier and gives you what you need if you’re audited.
Open a Business Bank Account
Mixing personal and business money is a mistake even for sole proprietors, and for LLC owners it can be a serious one: if a court decides your LLC isn’t really operating as a separate entity, your liability protection can collapse. Route every dollar of business income into a dedicated account and pay every business expense from it.
Banks generally ask for the following when you open an account:14U.S. Small Business Administration. Open a Business Bank Account
- Your EIN (or SSN if you’re a sole proprietor without one)
- Formation documents, such as your Articles of Organization or certificate of formation
- An operating agreement if the LLC has multiple members
- A business license, if your jurisdiction requires one
Get Insurance and a Written Contract
Registration alone doesn’t protect you from what can go wrong on a job. Two policies matter for most contractors. General liability insurance covers physical risks: bodily injury to a third party or damage to a client’s property. Professional liability insurance, sometimes called errors and omissions, covers claims that your work caused a client financial harm through a mistake or oversight. Many clients require proof of coverage before signing.
Most states exempt sole proprietors and single-member LLCs with no employees from workers’ compensation insurance. Rules vary, though; some states use payroll thresholds and others treat certain industries, especially construction, differently. Confirm with your state’s workers’ compensation board.
Have a written contractor agreement in place before your first engagement. It should cover:
- Scope of work, including deliverables and deadlines
- Payment terms, invoicing schedule, and payment deadlines
- Who owns the intellectual property you create
- How either party can terminate the agreement and what happens to partially completed work
- Indemnification: who bears responsibility for damages caused by your actions or omissions
- Confidentiality protections for proprietary information
A good contract also reinforces your independent status by making clear that you control how the work is performed, that you’re not entitled to employee benefits, and that you handle your own taxes. That documentation matters if the IRS or a state agency ever questions whether you’re really a contractor.
Keep the Business in Good Standing
Registration isn’t a one-time event. Most states require LLCs to file an annual or biennial report and pay a recurring fee. Miss the deadline and the state can administratively dissolve your LLC, which means you lose the liability protection until you file for reinstatement and pay what you owe. Put the date on your calendar the moment you receive your formation documents.
Beyond annual reports, keep an eye on professional license and local permit renewals, which often carry fees or continuing education requirements; update your registered agent’s information with the state if the address changes; and stay on top of Schedule C at filing time and your quarterly payments through the year. The compliance load is light once it’s set up. Losing track of it is what turns a small deadline into a real problem.
