To become an independent contractor, you choose a business structure, get a federal tax ID, take care of any licenses your work requires, open a separate bank account, put written agreements in place with clients, and start paying your own taxes on a quarterly schedule. How to become an independent contractor is less a single decision than a sequence of small setup tasks, and getting them in the right order saves you money and legal trouble later. The federal steps below apply everywhere; your state adds a licensing and registration layer on top.
Pick a Business Structure
Most independent contractors start as sole proprietors. There’s no formal filing: you and the business are the same legal entity, all income flows onto your personal return, and all business debts are personally yours. It’s the simplest way to begin, and it comes with unlimited personal liability if a job goes wrong.
If you want a wall between your personal assets and your business obligations, a Limited Liability Company is the common alternative. An LLC is a separate legal entity, so a client suing over a project generally can’t reach your house or savings. You form one by filing articles of organization with your state’s Secretary of State. Filing fees vary widely, typically between about $35 and $500. Some states also require a registered agent, meaning a person or service designated to receive legal documents for the business.
Either way, self-employment tax under the Internal Revenue Code applies to your net earnings.1Office of the Law Revision Counsel. 26 USC 1402 – Definitions A sole proprietor reports business profit on Schedule C attached to the personal return. A single-member LLC does the same by default, though it can elect a different tax treatment.
Get an Employer Identification Number
An EIN is a nine-digit tax ID the IRS assigns to businesses. Even if you never hire anyone, you’ll need one to open a business bank account, and many clients require it before they’ll pay you. Sole proprietors can technically use their Social Security number, but an EIN keeps your SSN off invoices and contracts.
You apply on IRS Form SS-4. The fastest route is the IRS online application, which issues the number immediately at no cost.2Internal Revenue Service. Get an Employer Identification Number Print the confirmation notice when you finish. The IRS also mails an official CP 575 letter, which some banks and government agencies specifically request.3Internal Revenue Service. Instructions for Form SS-4
Register a Business Name if You’re Not Using Your Own
To operate under a name other than your own legal name, you register a “Doing Business As” name, sometimes called a trade name or fictitious business name. A sole proprietor named Jane Smith who wants to invoice as “Summit Digital Consulting” files a DBA. An LLC that wants to operate under a name different from the one in its articles of organization does the same.
Where you file varies. Some states handle DBAs at the state level, others require a county clerk filing, and a few require both. Fees generally run $10 to $150, and some jurisdictions require you to publish a notice in a local newspaper, which adds cost. Before you file, check whether the name is already in use or registered as a trademark in your field. Most state filing offices offer an online name-availability search.
Handle Licenses and Insurance
Many fields require an occupational license or permit before you can legally take clients. Construction, accounting, real estate, cosmetology, and healthcare-related services are commonly licensed at the state level, with requirements that can include proof of education, an exam, and specific insurance. Check your state’s licensing board for the occupation you’ll practice. Starting work without the required license can bring fines and void your contracts.
Even when coverage isn’t legally required, many clients want proof of it before signing. Two policies matter most:
- General liability insurance covers bodily injury or property damage during business operations, such as a client tripping over your equipment at a job site.
- Professional liability insurance, also called errors and omissions coverage, protects against claims that your work product or advice caused a client financial harm. If your deliverable is expertise rather than a physical product, this is the policy that matters.
General liability does not cover mistakes in professional judgment, and professional liability does not cover someone slipping on your floor. If your work involves both physical presence and expert advice, you may need both. Get quotes early, because the cost affects how you price your services.
Open a Separate Bank Account
This one is easy to skip and expensive to regret. Mixing personal and business money creates two problems. Bookkeeping becomes a mess at tax time because you have to untangle which transactions were which. And if you formed an LLC specifically to protect personal assets, commingling funds is one of the fastest ways a court can pierce the veil and hold you personally liable for business debts anyway. The whole point of the LLC evaporates if your finances show no real separation.
Most banks will ask for your EIN (or SSN for a sole proprietorship), your formation documents if you have an LLC, a business license if your field requires one, and personal ID.4U.S. Small Business Administration.

Pay yourself by transferring money to your personal account rather than swiping the business debit card at the grocery store.
Get the Client Paperwork Right
Before most clients will pay you, they need a completed IRS Form W-9. It provides your taxpayer ID so the client can file the required information return, and it’s where you certify whether you’re subject to backup withholding.5Internal Revenue Service. About Form W-9, Request for Taxpayer Identification Number and Certification Any client who pays you $600 or more in a year must report it to the IRS on Form 1099-NEC, and you should receive a copy by January 31 of the following year.6Internal Revenue Service. Instructions for Forms 1099-MISC and 1099-NEC You owe tax on all your income whether or not a 1099 is issued. The $600 figure is a reporting threshold for the client, not a tax threshold for you.
Beyond the W-9, a written service agreement is where you protect yourself and reinforce your contractor status. Three provisions do the most heavy lifting:
- Scope of work and deliverables. Define what you’ll produce, not how you’ll produce it. The contract should make clear you control your own methods, tools, and schedule.
- Payment structure. Specify project-based fees or hourly rates tied to deliverables. Avoid language that resembles a salary. State that you’re responsible for your own taxes, insurance, and benefits.
- Termination terms. Include a notice period and spell out how final payments for completed work will be handled.
Each of these reinforces the independence that separates a contractor from an employee. Clients who push back hard on these terms are sometimes telling you something about how they actually plan to manage the relationship.
Protect Your Independent Contractor Status
The IRS doesn’t just take your word that you’re a contractor. If the agency examines a working relationship and decides it looks more like employment, the client faces back employment taxes and you lose the tax treatment you’ve been relying on. The IRS looks at three categories of evidence:7Internal Revenue Service. Worker Classification 101 – Employee or Independent Contractor
- Behavioral control. Does the client dictate how and when the work gets done, or only the end result? Contractors control their own methods and schedules.
- Financial control. Do you have a significant investment in your own tools and equipment? Can you profit or lose money on a job? Do you offer services to the general public?
- Relationship of the parties. Is the work a key, ongoing part of the client’s regular business? Do you receive employee-type benefits like health insurance or paid vacation? A written contract stating contractor status helps but is not dispositive by itself.
The core test is control. If the person paying you has the right to direct not just what gets done but how it gets done, the IRS treats that as an employment relationship regardless of what the contract says.8Internal Revenue Service. Independent Contractor Defined
Pay Self-Employment Tax and Quarterly Estimates
As an employee, your employer pays half of your Social Security and Medicare taxes. As a contractor, you pay both halves. The self-employment tax rate is 15.3%: 12.4% for Social Security and 2.9% for Medicare.9Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes) For 2026, the Social Security portion applies only to the first $184,500 of your combined wages and net self-employment earnings.10Social Security Administration. Contribution and Benefit Base The Medicare portion has no cap. If your net self-employment income exceeds $200,000 ($250,000 if married filing jointly), you owe an additional 0.9% Medicare tax on the amount above that threshold.11Internal Revenue Service. Topic No. 560, Additional Medicare Tax
There’s a partial offset. You can deduct half of your self-employment tax when calculating adjusted gross income, which lowers your income tax bill.12Internal Revenue Service. Topic No. 554, Self-Employment Tax You don’t need to itemize to claim it; the adjustment is taken on Schedule 1 of Form 1040.
Quarterly Deadlines
Because no employer is withholding for you, you pay as you go through quarterly estimated tax payments. The 2026 deadlines are:13Internal Revenue Service. Form 1040-ES – 2026 – Estimated Tax for Individuals
- 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 payment if you file your 2026 return by February 1, 2027, and pay the full balance with it.
Avoiding an Underpayment Penalty
The IRS charges a penalty if you don’t pay enough during the year. You’re generally safe if your payments cover the lesser of 90% of your current-year tax or 100% of last year’s tax. If your prior-year adjusted gross income was above $150,000, the safe harbor rises to 110% of last year’s tax. You also won’t owe a penalty if the total tax due minus any withholding is less than $1,000.14Internal Revenue Service. Instructions for Form 2210 (2025)
Most new contractors underestimate that first-year bill because they’re used to seeing taxes disappear invisibly from a paycheck. A reasonable starting approach is to set aside 25 to 30% of every payment in a separate savings account until you have a better sense of your effective rate.
Keep Records and Stay in Good Standing
The IRS expects you to track all business income and expenses and to keep documentation supporting every number on your return: receipts, invoices, bank statements, mileage logs. Complete records speed up an examination if one comes; incomplete records make the outcome worse.15Internal Revenue Service. Publication 583 (12/2024), Starting a Business and Keeping Records Set up a basic bookkeeping system before your first client, even if it’s just a spreadsheet, and track every startup cost. Filing fees, equipment, software subscriptions, and professional service fees are generally deductible.
If you formed an LLC, most states require an annual or biennial report to keep the entity in good standing. Fees range from nothing in a handful of states to several hundred dollars, and missing the deadline can result in administrative dissolution. Mark the due date on your calendar the day you receive your formation documents.
One deduction is worth flagging because it’s often missed in year one. Self-employed individuals who pay for their own health insurance can deduct those premiums, including medical, dental, vision, and qualified long-term care coverage for themselves, a spouse, and dependents, directly from gross income. The deduction is available for any month you weren’t eligible for an employer-subsidized plan through a spouse or other source.16Internal Revenue Service. Instructions for Form 7206
