Setting up an LLC for contract work is generally worth it once your net profit consistently clears about $50,000 a year or your work carries real risk of client lawsuits or property damage. Below that line, the annual fees and paperwork often outweigh what you get back, and a sole proprietorship paired with a professional liability policy may cover you more cheaply. The right call depends on how much you earn, what kind of damage a bad project could cause, and how much of your personal savings you want sitting behind the business.
What You Already Are Without an LLC
The moment you accept your first contract payment, you’re a sole proprietor. No form creates this. It just happens, and most contractors don’t think about what it means until a client threatens to sue or an invoice goes to collections.
As a sole proprietor, you and the business are the same legal person. Income and deductions go on Schedule C of your personal return, and profits flow straight to you.1Internal Revenue Service. About Schedule C (Form 1040), Profit or Loss from Business (Sole Proprietorship) The downside is that your personal assets have no separation from business obligations. If the business is sued or can’t pay a debt, creditors can reach your savings, your car, and your home.
What an LLC Actually Protects
An LLC puts a legal entity between you and your contract work. When a client sues the LLC or a business debt goes unpaid, creditors are limited to the assets inside the LLC. Your personal accounts, home, and retirement savings sit on the other side of that wall.
This matters most if your work could cause meaningful financial harm to a client, if you visit client sites or interact with the public, or if unpaid invoices could put the business in debt. Without the wall, one bad project can reach everything you own.
Where the Shield Has Holes
An LLC is not a universal defense, and contractors who treat it as one get caught out. Three gaps are worth knowing before you decide.
It does not protect you from your own professional mistakes. If you personally do negligent work that harms a client, you can be held personally liable no matter what entity you work through. A consultant who gives bad advice, a developer who ships broken code, a designer whose deliverable costs a client money: all personally on the hook. The LLC guards against the business’s debts and obligations, not against the consequences of your own professional errors.
It also disappears the moment you sign a personal guarantee. Landlords, lenders, and some clients routinely require one, and the word “guaranty” is not always on the page. Any promise to be “responsible for” the LLC’s payments can have the same effect. Read every contract before you sign.
And it is not insurance. Professional liability insurance (sometimes called errors and omissions coverage) actually pays claims. An LLC only limits which assets a creditor can reach. For most contractors who need protection at all, the right combination is both: an LLC for personal asset separation, and a policy that covers the cost of defending and settling claims.
How the Taxes Change (and Don’t)
Forming a single-member LLC does not, by itself, change your federal income tax bill. The IRS calls a single-member LLC a “disregarded entity” and taxes you exactly like a sole proprietor.2Internal Revenue Service. Single Member Limited Liability Companies Income still runs through Schedule C.
What hurts contractors is self-employment tax: both the employer and employee halves of Social Security and Medicare. For 2026, that’s 12.4% for Social Security on net earnings up to $184,500 and 2.9% for Medicare on all net earnings, for a combined 15.3%.3Social Security Administration. Contribution and Benefit Base Earnings above $200,000 (single) or $250,000 (married filing jointly) pick up an extra 0.9% Medicare surtax. Half of your self-employment tax is deductible when calculating adjusted gross income, but the total load is still well above what a W-2 employee pays.
The S Corp Election
This is where an LLC starts to earn its keep for higher earners. An LLC can elect to be taxed as an S corporation by filing Form 2553 with the IRS.4Internal Revenue Service. About Form 2553, Election by a Small Business Corporation You’re still an LLC legally. Only the tax treatment changes.
The election lets you split your business income into two parts. The first is a salary you pay yourself, subject to Social Security and Medicare tax like any paycheck. The second is a distribution of the remaining profit, which still gets income tax but escapes Social Security and Medicare. On $120,000 of net profit with a $70,000 salary, the $50,000 distribution avoids roughly $7,650 in payroll tax.
The IRS requires that salary to be “reasonable compensation” for the work you actually do. There’s no bright-line number; courts weigh training, experience, time commitment, and what comparable businesses pay for similar services.5Internal Revenue Service. Wage Compensation for S Corporation Officers Setting the salary artificially low to maximize the distribution is the quickest way to draw an audit.
The election also adds real costs. You’ll run payroll, file a separate S corporation return on Form 1120-S, and generally pay higher accounting fees. Most tax professionals suggest the math starts working around $50,000 of consistent net profit. Below that, payroll and accounting costs eat the savings. Form 2553 has to be filed within the first two and a half months of your tax year to take effect that year, so plan ahead.
The 20% Qualified Business Income Deduction
Whether or not you form an LLC, you’re likely eligible for the Section 199A deduction, which lets you knock 20% off qualified business income before income tax. It was made permanent in 2025 and applies to sole proprietorships and LLCs taxed as sole proprietorships or S corporations.
For 2026, if your total taxable income is below $201,750 (single) or $403,500 (married filing jointly), the math is simple: 20% off your qualified business income. A contractor with $80,000 of net profit would cut taxable income by $16,000. Above those thresholds, contractors in “specified service trades or businesses” (consulting, accounting, health care, law, financial services, and any business whose principal asset is the owner’s reputation or skill) face a phase-out and eventually lose the deduction entirely. Engineering and architecture are specifically excluded from that restriction.
What It Costs to Run an LLC
A sole proprietorship costs nothing to maintain. An LLC does. Knowing the full annual number keeps the decision honest.
State filing fees for the Articles of Organization run from $35 to $500, with most states between $50 and $200. A handful of states also require newspaper publication of your formation notice, which can add several hundred dollars.
Ongoing costs stack up:
- Annual or biennial report fees, ranging from nothing in a few states to over $800 in the most expensive, with most under $150.
- A registered agent with a physical address in your formation state. You can serve as your own if you qualify, or hire a commercial agent for about $100 to $250 per year.
- Franchise or privilege tax in some states, charged whether or not the business earns anything. These range from $0 to $800.
- A separate business bank account. Many online banks offer free business checking; traditional banks may charge $10 to $15 a month without a minimum balance.
All in, a contractor in a low-fee state might spend under $200 a year to keep an LLC alive. One in a high-fee state with a franchise tax can spend $1,000 or more. If your contract income is modest, these numbers deserve weight.
When to Wait
Forming an LLC too early just adds cost and busywork. A few situations argue for staying a sole proprietor, at least for now.
If your net income is well under $50,000, the S Corp tax strategy is off the table and annual LLC fees eat into thin margins. The liability protection still has some value, but weigh it honestly against the cost. A freelance writer working from home faces much less exposure than a contractor wiring commercial buildings.
If your work carries little risk of lawsuits or property damage, a professional liability policy may cover you more efficiently than the entity would. Insurance pays claims. An LLC only limits which assets a claim can reach. For low-risk, low-revenue work, insurance alone is often the better first move.
If you’re testing a new line of contract work and don’t yet know whether it will last, running as a sole proprietor for the first year gives you time to see whether the income justifies formation. You can always form an LLC later and move the activity into it.
If You Form One, Keep the Shield Real
An LLC’s protection is only as strong as the separation you keep between yourself and the business. Courts can set the entity aside and hold you personally liable if you’ve been treating it as an extension of yourself. Lawyers call this “piercing the veil,” and it happens more than contractors expect.
The single most common trigger is commingling funds: paying personal expenses from the business account, depositing client checks into your personal account, or pulling money out without documenting it as a distribution. Even occasional personal charges on the business card weaken the wall if a court ever reviews your records.
Courts also look at whether the LLC is underfunded for its obligations, whether you ignore your operating agreement, whether you keep basic records of business decisions, and whether the entity shows up as anything more than a formality. The fix is routine: separate accounts for everything, documentation whenever money moves between you and the business, an operating agreement you actually follow, and state reports filed on time. A few minutes a month is the whole reason the protection holds up when it’s tested.
