LLC, S-Corp, or Sole Prop? The $10,000 Decision

Ryan ran a one-man landscaping business in Texas. For two years, he operated as a sole proprietor. Simple. No paperwork. Just him, his truck, and a Schedule C at tax time.

Then he got hit with a $14,000 self-employment tax bill. He had grossed $92,000. After expenses, he netted $62,000. He thought his tax bill would be around $8,000. It was nearly double.

His accountant explained: as a sole proprietor, Ryan paid 15.3% self-employment tax on every dollar of profit. That is $9,486 right there. Add federal and state income tax, and the bill made sense. It just hurt.

The accountant ran the numbers on an S-corp election. If Ryan paid himself a $45,000 salary and took the remaining $17,000 as distributions, his self-employment tax would drop by $2,600. Every year.

Ryan filed the S-corp election the next week.

This is the decision most contractors never make intentionally. They pick a business structure by accident (sole prop by default) or on bad advice (an LLC because someone said to). Then they pay thousands more in taxes than they need to.

The Four Structures (And When Each Makes Sense)

Sole Proprietorship: You are the business. No separation. You report income and expenses on Schedule C. If someone sues the business, they sue you personally. Your house, your truck, your savings are all on the table.

This makes sense if you are just starting out, making under $30,000/year, and have minimal liability risk. It is simple and cheap. But it is a stepping stone, not a destination.

LLC (Limited Liability Company): You create a legal entity separate from yourself. If the business gets sued, your personal assets are protected (assuming you maintain the separation properly).

By default, a single-member LLC is taxed like a sole proprietorship. You still pay self-employment tax on all profit. The value of an LLC is liability protection, not tax savings.

LLCs cost $100-500 to set up depending on the state, plus annual fees and paperwork. For most contractors grossing over $50,000/year, the liability protection is worth it.

S-Corporation (S-corp): This is not a business structure. It is a tax election. You can be an LLC taxed as an S-corp, or a corporation taxed as an S-corp.

Here is the key difference: S-corp owners pay themselves a "reasonable salary" via W-2 payroll. That salary is subject to self-employment tax. But any profit beyond the salary can be taken as distributions, which are not subject to self-employment tax.

The break-even point is usually around $60,000-70,000 in profit. Below that, the payroll and accounting costs outweigh the tax savings. Above that, an S-corp can save you $2,000-10,000/year depending on your profit level.

C-Corporation (C-corp): Taxed separately from the owner. The business pays corporate tax on profit, then you pay personal tax on any salary or dividends you take. This "double taxation" makes C-corps a poor fit for most small contractors.

C-corps make sense for businesses seeking outside investment or planning to go public. For a solo contractor or small crew, it is almost always the wrong choice.

The Real Cost of Each Structure

Sole proprietor: $0 to start. No ongoing costs beyond your normal tax prep.

LLC: $100-500 to file (varies by state). Some states (California, New York) charge annual fees ($800+ in California). You will want an accountant to help with taxes ($500-1,500/year).

S-corp: Costs of an LLC, plus payroll processing ($500-1,500/year), plus additional accounting ($1,000-3,000/year). Total incremental cost: $2,000-5,000/year.

You need to save more in taxes than you spend on compliance. For most contractors, that threshold is around $60,000 in net profit.

The Liability Protection Everyone Misunderstands

An LLC protects your personal assets from business liabilities. If a client sues your business for property damage, they can only go after business assets (your truck, your tools, your business bank account). They cannot touch your house or personal savings.

But that protection evaporates if you:

Commingle funds (paying personal expenses from the business account or vice versa)
Operate without proper insurance
Commit fraud or gross negligence

An LLC does not protect you from your own actions. If you personally cause harm (you injure someone on a job site due to negligence), you can still be sued personally.

The real value of an LLC is separating business risk from personal risk. A client can sue your business over a billing dispute without putting your family home at risk. That is worth the filing fee.

When to Elect S-Corp Status (And When to Wait)

The S-corp tax benefit comes from splitting your income into salary and distributions. The salary gets payroll taxes (15.3% self-employment tax). The distributions do not.

But the IRS requires you to pay yourself a "reasonable salary" for the work you do. You cannot pay yourself $20,000 and take $80,000 in distributions. The IRS will reclassify those distributions as salary and hit you with penalties.

A reasonable salary for a working contractor is usually 40-60% of net profit. If you net $100,000, you might pay yourself $50,000-60,000 in salary and take $40,000-50,000 in distributions. Your self-employment tax savings would be around $6,000-7,500.

Run the math:

Net profit: $100,000
Sole prop self-employment tax: $15,300
S-corp (assume $55,000 salary, $45,000 distribution): $8,415 self-employment tax
Savings: $6,885
S-corp costs (payroll + accounting): $3,000
Net benefit: $3,885

At $60,000 net profit, the savings are smaller ($2,000-3,000). At $150,000, the savings are bigger ($8,000-12,000).

Most accountants recommend S-corp election once you are consistently netting over $60,000-70,000/year.

The Paperwork You Cannot Skip

If you form an LLC, you must:

Keep business and personal finances completely separate (separate bank account, separate credit card)
File annual reports with the state (deadlines vary, penalties for missing them are steep)
Maintain proper records (meeting minutes if you have partners, operating agreement even if you do not)

If you elect S-corp status, you must:

Run payroll (quarterly payroll tax filings, annual W-2s and W-3s)
File a separate business tax return (Form 1120-S) even if you are a single owner
Pay yourself via payroll at least quarterly (some recommend monthly to avoid cash flow issues)

These are not optional. Failing to maintain proper S-corp formalities can result in the IRS revoking your election and retroactively taxing you as a sole proprietor. With penalties.

Hire a payroll service ($40-100/month) and a competent accountant. The cost is trivial compared to the risk.

State-Specific Gotchas

California charges LLCs an $800 annual fee regardless of revenue. Texas has no state income tax, so S-corp benefits are smaller. New York requires LLCs to publish formation notices in newspapers, which can cost $1,000+.

Delaware is popular for incorporation (low fees, business-friendly courts), but if you operate in another state, you will still need to register there as a "foreign LLC," which doubles your filing fees.

For most contractors, form your LLC in the state where you do business. The added complexity of out-of-state formation rarely justifies the minor benefits.

The One-Hour Conversation That Saves You Thousands

Do not pick a business structure based on a blog post (including this one). Sit down with a CPA who works with contractors.

Bring your last two years of tax returns. Ask:

Based on my profit level, what structure makes sense?
At what profit level should I consider S-corp election?
What will compliance cost me annually?
Are there state-specific issues I should know about?

A good accountant will run the numbers, show you the tax savings, and help you decide. This conversation costs $200-500. It can save you $5,000-10,000/year.

Ryan's $2,600 annual tax savings from his S-corp election compounded. Over five years, he saved $13,000. Over ten years, $26,000. That is a new truck. That is a down payment on a shop. That is retirement savings.

Your business structure is not permanent. You can start as a sole prop, move to an LLC when revenue justifies it, and elect S-corp status when profit justifies it. But make the transitions intentionally, not by default.

The worst business structure is the one you picked because someone on the internet said to. The best business structure is the one your accountant recommended based on your actual numbers.
