Sole Proprietor vs LLC vs S-Corp for Houston Service Businesses: 2026 Tax Comparison

Key Takeaways

• An LLC and a sole proprietorship are taxed the same by the IRS by default. The LLC buys you liability protection, not a lower tax bill.

• The S-Corp election is where real tax savings live, but only above roughly $80k to $90k in net profit once payroll and filing costs are covered.

• Texas has no state income tax, so the whole comparison comes down to federal self-employment tax and the franchise tax, which most small firms owe nothing on under $2.47 million in revenue.

• At $50k profit the S-Corp rarely pays for itself. At $100k it saves most owners $3,000 to $5,000. At $200k it commonly saves $8,000 to $12,000.

• The right answer changes as you grow. Many Houston service owners start as an LLC and elect S-Corp status the year profit clears $90k.

What These Three Structures Actually Are

There is a lot of confusion here, so start with the plain version. A sole proprietorship is the default. You do work, you get paid, you report it on your personal return. No paperwork, no filing fee, nothing to set up. A single-member LLC is a legal wrapper around that same activity. It separates your personal assets from the business, so if a client sues your landscaping crew or your salon, they are generally coming after the business, not your house. An S-Corp is not a business type at all. It is a tax election you place on top of an LLC (or a corporation) by filing IRS Form 2553.

That last point trips up most Houston owners. You do not go to the Texas Secretary of State and register an S-Corp. You form an LLC first, then you ask the IRS to tax that LLC as an S-Corp. This matters because it means the S-Corp decision is reversible and profit-driven, while the LLC decision is mostly about protecting what you own.

• Sole proprietor: zero setup, personal liability, taxed on Schedule C.

• LLC: liability protection, small state filing fee, taxed exactly like a sole prop by default.

• S-Corp: a tax election on top of an LLC, files its own return, can cut self-employment tax at higher profit.

The Real Difference: How Each One Is Taxed

Here is the mechanic that drives every dollar in this article. As a sole proprietor or default LLC, every dollar of profit is hit with self-employment tax at 15.3 percent (12.4 percent Social Security plus 2.9 percent Medicare) on top of your regular income tax. On $100,000 of profit, that self-employment layer alone is roughly $14,100 before you touch income tax.

An S-Corp splits your profit into two buckets: a reasonable salary you pay yourself through payroll, and distributions. The salary is subject to payroll tax, but the distributions are not. So if you take a $60,000 salary and $40,000 in distributions, you only pay the 15.3 percent on the $60,000, not the full $100,000. That gap is the entire reason the S-Corp exists as a tax play. The catch is that the IRS requires the salary to be reasonable for your role and market, and running payroll plus a separate business return costs money. Those costs are why the math only works above a certain profit line.

Side-by-Side at $50k, $100k, and $200k Profit

Numbers make this concrete. The figures below assume a Houston service business (think HVAC, cleaning, salon, landscaping, general contracting) with the profit shown after expenses, and they isolate the self-employment and payroll tax layer since that is where the structures actually differ. Income tax is roughly the same across all three because Texas has no state income tax and the IRS taxes your total income either way.

• At $50k profit. Sole prop / LLC: about $7,065 in self-employment tax, no separate return. S-Corp: a reasonable salary eats most of the profit, so savings land near $500 to $1,500 and often get wiped out by the extra $1,500 to $2,500 in payroll and filing costs. Verdict: usually not worth it yet.

• At $100k profit. Sole prop / LLC: about $14,100 in self-employment tax. S-Corp: with a $60k salary and $40k distribution you save roughly $5,000 to $6,000 in payroll tax, netting $3,000 to $4,500 after the added compliance cost. Verdict: for most owners, this is where it starts paying off.

• At $200k profit. Sole prop / LLC: the tax caps on the Social Security portion but Medicare keeps running. S-Corp: with a salary around $90k to $110k and the rest in distributions, savings commonly hit $8,000 to $12,000 net of costs. Verdict: leaving this on the table is expensive.

The Texas Advantage: No State Income Tax

This is where being a Houston business changes the calculus. In states like California or New York, an owner also weighs state income tax and sometimes an extra fee just for having an S-Corp. In Texas, none of that applies. There is no personal state income tax, so your salary and distributions are not taxed at the state level at all. That makes the federal self-employment savings cleaner and easier to capture than they are almost anywhere else.

The one Texas-specific item to know is the franchise tax. It applies to LLCs and corporations, but the no-tax-due threshold is $2.47 million in annual revenue. If your service business brings in less than that, you file a simple report and owe nothing. Almost every small Houston service firm sits comfortably under it. So for practical purposes, the structure choice here is a pure federal tax question, which is exactly why the S-Corp election is more attractive for Texas owners than for owners in high-tax states.

When the S-Corp Switch Actually Saves Money

The honest threshold is around $80,000 to $90,000 in net profit. Below that, the payroll service, the extra tax return, and the bookkeeping discipline an S-Corp demands usually cost more than they save. Above it, the savings compound every year you stay elected. If you want the deeper breakdown of the exact income point where an S-Corp saves money, we walk through it case by case in a dedicated guide.

Timing matters too. You generally want to make the election before the tax year you expect to clear that profit line, and you have to actually run payroll during the year, not reconstruct it in April. A common Houston pattern: an owner operates as an LLC for the first year or two while revenue is lumpy, then elects S-Corp status the year they can see profit landing north of $90k and holding there. If you are unsure whether your numbers are stable enough to commit, that is a good moment to talk to a CPA rather than guess.

Choose Your Structure: Three Clear Buckets

You do not need a spreadsheet to make the first-pass call. Match yourself to one of these buckets and you will be right most of the time. Deciding whether you even need a professional to run these numbers is its own question, and knowing when to hire a Houston CPA versus handling it yourself is worth reading before you commit either way.

• Choose a sole proprietorship if you are just starting, testing an idea, or netting under about $40k with low liability risk. Keep it simple until the money justifies the paperwork.

• Choose an LLC (taxed as default) if you want liability protection between your business and your personal assets, or you have any exposure (customers on your property, employees, physical work), but your profit is still under roughly $80k. Same tax bill as a sole prop, better protection.

• Choose an LLC with an S-Corp election if your net profit is holding above $90k, your revenue is stable enough to run consistent payroll, and you are ready to keep clean books all year. This is the bucket where you leave real money on the table by waiting.

What It Costs to Set Up and Maintain Each

Real numbers, because vague answers help nobody. A sole proprietorship costs nothing to start and nothing extra to maintain beyond your normal personal return. A Texas LLC costs a one-time $300 state filing fee, and you can do it yourself or pay a preparer $200 to $500 to set it up correctly with an EIN and operating agreement.

The S-Corp is where ongoing cost enters. Expect payroll processing to run $40 to $80 a month, and a separate S-Corp tax return (Form 1120-S) to cost $800 to $1,800 a year depending on complexity. Bookkeeping, if you are not already doing it, adds $150 to $500 a month. Add it up and an S-Corp typically carries $2,000 to $4,000 in yearly overhead the other structures do not. That is exactly why the $100k profit line matters: below it, the overhead can swallow the savings; above it, the savings dwarf the overhead. When you factor real dollars in, the decision stops being a preference and becomes arithmetic.

Common Mistakes Houston Service Owners Make

The most expensive mistake is electing S-Corp status and then paying yourself no salary, or an unreasonably low one, to dodge payroll tax entirely. The IRS watches this closely, and getting caught means back taxes, penalties, and interest. The second is electing too early, at $50k profit, and bleeding cash on payroll and filing fees that outweigh any benefit. The third is treating the LLC as a tax strategy. It is not. It protects your assets, but by itself it does not change what you owe.

Frequently Asked Questions

Is an LLC taxed differently than a sole proprietorship?

No, not by default. This surprises almost every owner. A single-member LLC is treated by the IRS as a disregarded entity, which means you report the exact same way a sole proprietor does, on Schedule C, and you pay the same 15.3 percent self-employment tax on your profit. The LLC changes your legal standing, not your tax bill. What it buys you is liability protection, a wall between your business and your personal assets like your home and savings. So if the reason you formed an LLC was to lower taxes, that alone did not do it. The tax savings only arrive when you layer an S-Corp election on top of that LLC, and only once your profit is high enough to justify the added payroll and filing costs.

At what profit level should a Houston service business become an S-Corp?

For a closer look, see Boutique CPA vs Big 4 vs H&R Block in Houston: 2026 Service & Price Comparison.

The practical line sits around $80,000 to $90,000 in net profit after expenses. Below that, the ongoing cost of running payroll, filing a separate S-Corp return, and keeping tighter books usually eats up any tax savings. At $100,000 profit most owners save $3,000 to $4,500 per year net of those costs, and at $200,000 the net savings commonly reach $8,000 to $12,000. The other factor is stability. You want revenue predictable enough to pay yourself a consistent salary through the year, because the IRS expects real payroll, not a year-end adjustment. Many Houston owners run as a plain LLC for a year or two, then elect S-Corp status the year profit clearly clears $90,000 and holds there.

Does Texas having no state income tax change the decision?

Yes, in your favor. In high-tax states, owners have to weigh state income tax and sometimes an extra state-level S-Corp fee, which can shrink the benefit. Texas has neither. There is no personal state income tax on your salary or your distributions, so the federal self-employment savings from an S-Corp come through cleanly. The only Texas-specific tax to know is the franchise tax, and its no-tax-due threshold is $2.47 million in annual revenue. Nearly every small service business sits well under that, files a short report, and owes nothing. Put simply, the structure choice for a Houston business is almost purely a federal question, which makes the S-Corp election more valuable here than in most states. That is a real, if quiet, advantage of operating in Texas.

What is a reasonable salary for an S-Corp owner?

A reasonable salary is what you would have to pay someone else to do your job in the Houston market. The IRS does not publish a fixed number, but it looks at your role, your industry, your hours, and comparable wages. For a service business owner netting $100,000, a salary in the $50,000 to $65,000 range is common and defensible. For $200,000 in profit, salaries often land around $90,000 to $110,000. Paying yourself too little to avoid payroll tax is the single most audited S-Corp mistake, and losing that argument means back taxes plus penalties and interest. The safe approach is to document how you set the number, using industry wage data, and keep it consistent. A CPA can help you land on a figure that captures savings without inviting scrutiny.

Can I switch structures later, or am I locked in?

Our guide How Much Does a CPA Cost in Houston? A 2026 Pricing Guide covers the next steps.

You are not locked in. This is one of the most reassuring parts of the decision. You can start as a sole proprietor, form an LLC whenever you want liability protection, and add or drop the S-Corp election as your profit changes. The S-Corp election is made by filing Form 2553 with the IRS, and there are timing rules, generally you want it in place before or early in the tax year it should apply to. Revoking it later is also possible, though the IRS asks you to wait five years before re-electing if you reverse course. The takeaway: pick the structure that fits your numbers today, and revisit it every year as profit grows. Most owners move up the ladder over time rather than picking a final answer on day one.

How much does it actually cost to run an S-Corp each year?

Plan on $2,000 to $4,000 in annual overhead that a sole prop or plain LLC does not carry. That breaks down into payroll processing at roughly $40 to $80 a month, a separate S-Corp tax return (Form 1120-S) at $800 to $1,800 per year, and bookkeeping at $150 to $500 a month if you are not already handling it well. The upfront LLC formation is a one-time $300 Texas filing fee, plus $200 to $500 if you hire someone to set it up cleanly with an EIN. This overhead is precisely why profit level matters so much. At $50,000 profit it can swallow your savings whole. At $150,000 or $200,000, the savings are several times the overhead, and the election is close to a no-brainer.

Do I need an LLC before I can elect S-Corp status?

You need an eligible entity first, and for most Houston service owners that means an LLC. You cannot simply register an S-Corp with the state, because S-Corp is a federal tax classification, not a business type. The usual path is to form a single-member LLC with the Texas Secretary of State, get an EIN from the IRS, and then file Form 2553 to have that LLC taxed as an S-Corp. A corporation can also make the election, but LLCs are simpler and more flexible for service businesses, so that is the route almost everyone takes. If you already operate as a sole proprietor, you would form the LLC first, then make the election. The two steps are separate, and the order matters.

What happens if I never form anything and just operate as myself?

You are automatically a sole proprietor, and that is perfectly legal. You report income and expenses on Schedule C, pay self-employment tax and income tax, and owe nothing to form or maintain the arrangement. The two real downsides are liability and taxes at scale. Without an LLC, a lawsuit or business debt can reach your personal assets, which is a genuine risk for any service business with customers, employees, or work performed on someone else's property. And without an S-Corp election, you pay the full 15.3 percent self-employment tax on every dollar of profit, which gets expensive fast past $80,000. For a brand-new, low-risk, low-profit venture, staying a sole proprietor is fine. As money and exposure grow, standing still starts costing you real dollars.
