Forming a plain LLC changes nothing about your federal tax bill — a single-member LLC is a disregarded entity by default, taxed exactly like a sole proprietor, so 100% of your net 1099 travel nursing profit still hits the 15.3% self-employment tax. The actual savings come from electing S-corp tax status, which splits your income into a salary (taxed) and a distribution (not subject to self-employment tax). That election adds real payroll and filing costs, so it only pays off once your net profit clears a meaningful threshold.
Key takeaways
- An LLC by itself is a liability shield, not a tax strategy — a single-member LLC is taxed identically to a sole proprietor unless you separately elect S-corp status.
- S-corp status lets you split profit into salary (subject to payroll tax) and distributions (not subject to the 15.3% self-employment tax) — but the salary must be "reasonable" for the work performed.
- The 2026 self-employment tax rate is 15.3% (12.4% Social Security up to the $184,500 wage base, plus 2.9% Medicare with no cap) on 92.35% of your net self-employment earnings.
- S-corp status adds real costs — payroll processing, a separate Form 1120-S return, and often state filing fees — so it typically only makes sense once net profit clears the low six figures.
An LLC alone changes nothing about your tax bill
A single-member LLC is, by IRS default, a "disregarded entity" — the IRS taxes it exactly like a sole proprietorship. Your travel nursing income and expenses still flow onto Schedule C of your personal return, and your full net profit is still subject to the 15.3% self-employment tax that funds Social Security and Medicare. The full mechanics of that tax and how it compares to W2 withholding are covered in 1099 Travel Nurse Taxes. Forming the LLC buys you personal liability protection and a more professional business structure — real benefits, just not tax ones.
What actually creates the savings: the S-corp election
An LLC (or a corporation) can elect to be taxed as an S-corporation by filing Form 2553 with the IRS, generally due within 2 months and 15 days of forming the entity, or by March 15 for the election to apply to the current tax year. Once elected, you become an employee of your own company: you pay yourself a "reasonable salary" for the work you actually perform, run it through payroll with normal FICA withholding, and take any remaining profit as a distribution. Distributions are not subject to Social Security or Medicare tax — that gap is the entire savings mechanism. The IRS actively scrutinizes S-corps that pay an unreasonably low salary specifically to dodge payroll tax, so the salary has to reflect what a comparable employee (an agency staff nurse, in this case) would actually earn for the work.
A worked example
Say your 1099 travel nursing business nets $90,000 in profit for the year after business expenses.
- As a sole proprietor or plain LLC: self-employment tax applies to 92.35% of net earnings — $90,000 × 92.35% = $83,115 — at 15.3%, for a self-employment tax bill of about $12,717.
- As an S-corp paying a $55,000 reasonable salary and $35,000 in distributions: payroll (FICA) tax applies only to the $55,000 salary — $55,000 × 15.3% ≈ $8,415. The $35,000 distribution owes no Social Security or Medicare tax at all.
That’s roughly $4,300 saved on payroll/self-employment tax for the year in this example — before subtracting what the S-corp itself costs to run.
What an S-corp costs you
The savings aren’t free. Running an S-corp typically means a payroll service to process your own salary correctly (commonly on the order of a few hundred to over a thousand dollars a year), a separate business tax return (Form 1120-S) in addition to your personal return, and in many states, an annual LLC or corporate filing fee. Set the salary too low and you risk an IRS reasonable-compensation challenge — including back payroll taxes, penalties, and interest on top of what you were trying to save.
So when does it actually make sense?
The math is directional, not a fixed rule: at low net profit, the fixed costs of payroll and a second tax return can eat most or all of the self-employment tax you’d save, making a plain LLC or sole proprietorship the simpler and cheaper choice. At higher net profit, the same fixed costs shrink relative to a larger absolute savings, and the S-corp election tends to pay for itself. Where exactly that crossover sits depends on your specific state’s fees, your payroll costs, and your actual profit — which is why this is a numbers-first decision to run with a CPA who works with 1099 travel nurses specifically, not a blanket recommendation. See DIY Tax Software vs. a Travel-Nurse CPA for how to find one. And regardless of entity choice, 1099 income still requires quarterly estimated payments — covered in Quarterly Estimated Taxes for 1099 Travel Nurses.
Before choosing 1099 at all, compare the real after-tax numbers against a W2 offer for the same contract with the W2 vs. 1099 Calculator — entity structure only matters once you’ve confirmed 1099 is the better fit in the first place.
FAQ
Does forming an LLC lower my taxes as a 1099 travel nurse?
No, not by itself. A single-member LLC is taxed exactly like a sole proprietorship by default. Tax savings only come from separately electing S-corp status.
What’s a "reasonable salary" for a travel nurse S-corp?
It should reflect what a comparable W2 staff or travel nurse would be paid for the same work — not an arbitrarily low number chosen to minimize payroll tax. The IRS can reclassify distributions as wages, with back taxes and penalties, if the salary looks designed to avoid FICA.
How much can an S-corp actually save a travel nurse?
It depends entirely on your net profit and how you split salary versus distributions. On $90,000 of net profit split roughly 60/40 toward salary, the example above shows about $4,300 in payroll tax savings before subtracting the cost of running the S-corp.
Do I still owe self-employment tax on an S-corp salary?
You owe the equivalent — standard Social Security and Medicare payroll tax — on the salary portion only, split between employer and employee shares. Only the distribution portion escapes that tax.
Is an LLC still worth it if I don’t elect S-corp status?
It can be, for liability protection and a more professional business structure, even with no change to your federal tax bill. Just don’t form one expecting tax savings unless you also make the S-corp election.
