LLC vs S-Corp vs Sole Proprietor: Which Saves You the Most on Taxes? (2026)

By TraxGig Team · July 5, 2026 · 12 min read

"Should I form an LLC?" is the most common question self-employed people ask once the money starts coming in — usually because someone told them it would lower their taxes. The honest answer is more nuanced, and getting it right can be worth thousands of dollars a year. This guide explains how each business structure is actually taxed, clears up the biggest myth about LLCs, and shows you the specific income level where switching structures starts to pay off.

First, separate two things people constantly confuse

The confusion around this topic comes from mixing up two different decisions:

  • Legal structure — sole proprietorship, LLC, corporation. This is about liability protection and how your business legally exists.
  • Tax classification — how the IRS taxes that entity. This is what actually determines your tax bill.

Here is the part almost no one explains clearly: an LLC by itself does not change your taxes at all. A single-member LLC is taxed exactly like a sole proprietorship by default. It gives you liability protection and a professional structure, but on its own it saves you $0 in tax. The tax savings people associate with an "LLC" actually come from a separate step — electing to be taxed as an S-corporation — which an LLC can do but doesn't do automatically.

Option 1: Sole proprietor (and single-member LLC)

This is where nearly every self-employed person starts, whether they formally register anything or not. If you earn money on your own and haven't set up anything else, you are a sole proprietor.

  • You report business income and expenses on Schedule C with your personal return.
  • Your net profit is subject to ordinary income tax and the full 15.3% self-employment tax.
  • No separate business tax return, no payroll — the simplest possible setup.

A single-member LLC works identically for taxes; it just adds legal separation between you and the business. For most people earning under roughly $60,000 in net profit, this simplicity is exactly right and there's little tax benefit to anything more complex.

Option 2: The S-corp election — where the real savings live

An S-corporation isn't a different legal entity you form from scratch; it's a tax electionyou make (using IRS Form 2553) for an LLC or corporation you already have. Here's the mechanism that saves money:

As a sole proprietor, all your net profit is hit with the 15.3% self-employment tax. As an S-corp, you split your income into two buckets:

  • A reasonable salary you pay yourself as a W-2 employee — this portion is subject to payroll taxes (the equivalent of that 15.3%).
  • Remaining profit taken as distributions — this portion is not subject to self-employment or payroll tax at all.

That second bucket is the saving. By moving part of your income from "salary" to "distribution," you legally avoid the 15.3% tax on that slice.

A concrete example

Say your business nets $120,000 in profit after expenses.

Sole proprietorS-corp election
Net profit$120,000$120,000
Reasonable salaryN/A$70,000 (payroll taxed)
DistributionsN/A$50,000 (no SE tax)
Income subject to 15.3%~$110,800~$70,000
Approx. SE / payroll tax~$16,950~$10,710
Rough annual saving~$6,200 before costs

Even after subtracting the added costs of running an S-corp — payroll software, a separate business tax return, and a bookkeeper — someone at this income level often nets several thousand dollars in savings.

The catches nobody mentions

The S-corp election is powerful but comes with real obligations. Ignore them and the savings evaporate — or turn into penalties:

  • "Reasonable" salary is required.You can't pay yourself a $10,000 salary and take $110,000 in distributions. The IRS requires your salary to reflect what the work is genuinely worth, and this is an area they scrutinize.
  • You must run actual payroll. That means withholding, payroll filings, and usually paying for payroll software or a service.
  • A separate tax return (Form 1120-S) is required, so your accounting costs rise.
  • More administrative overhead overall — this only makes sense once the savings clearly exceed the added cost and hassle.

A widely used rule of thumb: the S-corp election tends to start paying off once your business nets somewhere around $60,000–$80,000 in profit. Below that, the extra costs usually eat the savings. Above it, the case gets stronger with every additional dollar. Your exact break-even depends on your salary, state, and admin costs — worth modeling before you elect.

What about the 20% QBI deduction?

The Qualified Business Income (QBI) deduction can let many self-employed people deduct up to 20% of their business income, and it applies to sole proprietors, LLCs, and S-corps alike. It interacts with your structure in ways that matter — for example, an S-corp salary isn't QBI, which can slightly reduce the deduction. This is one of several reasons the "best" structure isn't universal and depends on your numbers.

A simple decision framework

  1. Just starting or earning modestly?Stay a sole proprietor. Keep clean records and focus on tracking deductions — that's where your easy wins are.
  2. Want liability protection?Form an LLC. Understand it protects you legally but doesn't change your taxes yet.
  3. Consistently netting $60k–$80k or more? Run the numbers on an S-corp election with a professional. This is where structure starts saving real money.
  4. Whatever you choose,track income and expenses rigorously. No structure saves as much as simply capturing every deduction you're entitled to.

Before you can decide whether an S-corp is worth it, you need to know your true net profit. TraxGig tracks your income and deductions in one place so you always know the number that drives this decision. Start tracking free.

The bottom line

An LLC protects you legally but doesn't lower your taxes on its own. The real tax savings come from the S-corp election, and only once your profit is high enough to outweigh the added cost and complexity — typically in the $60k–$80k range and up. Until then, the sole proprietor setup is not a compromise; it's the smart, low-overhead choice. Get your recordkeeping tight first, and revisit your structure as your income grows.
