Key Takeaways
- An S corp is a tax election, not a separate legal entity. A Texas LLC can elect S corp status with the IRS without forming a corporation.
- The primary S corp advantage is self-employment tax savings. By splitting income between a W-2 salary and shareholder distributions, business owners reduce Social Security and Medicare tax exposure.
- The IRS scrutinizes reasonable compensation closely. Paying an unreasonably low salary to maximize distributions is one of the most audited practices among S corp owners.
- S corp election has real restrictions. No more than 100 shareholders, U.S. citizens and residents only, one class of stock.
- The right answer depends on net profit level, owner involvement, and growth plans. A business tax attorney who holds a CPA license can model both scenarios before the election is filed.
Houston has more new business formations per year than almost any other city in the country. And nearly every one of those founders, at some point, faces the same question: LLC or S corp?
Most get incomplete answers. A quick search returns generic advice built around national averages. An accountant says one thing. A business attorney says another. And the decision gets made based on what a colleague did or what seemed simplest at the time.
That’s a costly way to choose a tax structure. The difference between the right and wrong choice — based on actual net profit, owner compensation, and growth trajectory — can add up to tens of thousands of dollars over a few years.
What business tax attorney services do that a general search can’t is model both scenarios against real numbers before the election is ever filed. That’s where the decision gets made correctly.
LLC vs S Corp Tax Implications: What the Comparison Is Actually About
The first thing to understand is that comparing an LLC to an S corp is not quite an apples-to-apples comparison.
An LLC is a legal entity structure. An S corp is a federal tax classification. A Texas LLC can elect to be taxed as an S corp by filing IRS Form 2553 — which means the business retains its LLC legal structure while being taxed differently at the federal level.
Most Houston business owners who choose S corp treatment aren’t forming a corporation. They’re forming an LLC and making a tax election. That distinction matters because it keeps the flexibility and simplicity of an LLC while potentially capturing the tax advantages of S corp treatment.
How a Default LLC Is Taxed
A single-member LLC is taxed as a sole proprietorship by default. A multi-member LLC is taxed as a partnership. In both cases, the LLC itself pays no federal income tax — all profits pass through to the owner’s personal return.
The catch is self-employment tax. LLC members who actively work in the business pay self-employment tax — currently 15.3% on earnings up to the Social Security wage base, and 2.9% above that — on the full net profit of the business.
For a business generating $150,000 in net profit, that’s a meaningful number. The LLC structure is simple and flexible, but the self-employment tax exposure grows directly with the business.
How S Corp Tax Treatment Changes the Picture
When an LLC elects S corp status, the owner must be put on payroll and receive a W-2 salary. The remaining profits can then be taken as shareholder distributions.
The tax advantage: payroll taxes apply only to the W-2 salary, not to the distributions. Only the salary portion is subject to Social Security and Medicare. The distributions pass through to the owner’s personal return as ordinary income but avoid the self-employment tax entirely.
On a $150,000 net profit, an owner paying themselves a $75,000 salary and taking $75,000 as distributions might save $10,000 to $12,000 in annual self-employment taxes.
That savings is real. But it comes with conditions.
The Reasonable Compensation Requirement — and Why It’s the Biggest Risk
The IRS is well aware of the salary-and-distributions strategy. It’s one of the most audited practices among S corp owners, and for good reason: the agency has seen the strategy abused aggressively.
The rule is that an S corp owner who performs services for the business must receive a reasonable salary — one that reflects what the market would pay for those same services in an arm’s-length transaction. The IRS does not define a specific formula, but it looks at comparable wages, the nature and extent of services performed, and the profitability of the business.
Paying an artificially low salary to maximize distributions is a compliance problem, not a planning strategy. The IRS can reclassify distributions as wages, assess back payroll taxes, and add penalties and interest on top of that.
The salary question is where the CPA and legal dimensions of this decision intersect. That’s exactly the combination Phillip Mixon’s CPA/JD background brings to the analysis — the accounting depth to model the numbers and the legal knowledge to stay on the right side of the line.
When S Corp Election Generally Makes Sense
The S corp election isn’t the right move for every business. A few factors determine whether it pencils out.
Net profit level matters
Most advisors use a rough threshold of $40,000 to $50,000 in net profit as the floor where S corp election starts to make economic sense. Below that, the payroll costs, accounting fees, and compliance burden often outweigh what’s saved.
Owner involvement matters
The reasonable compensation requirement means owners who work full-time in the business need a salary that reflects that. A business where the owner is minimally involved looks different from one where the owner is the primary driver of revenue.
Growth plans matter
S corps come with ownership restrictions. No more than 100 shareholders. Only U.S. citizens and permanent residents can hold shares. Only one class of stock is allowed. The IRS.gov guidance on S corporations lays out the eligibility requirements and election procedures in full.
Texas-Specific Considerations
Texas has no state income tax. That removes one of the variables that drives S corp elections in high-income-tax states like California or New York. In Texas, the federal SE tax savings are the primary driver.
Texas does have a franchise tax — the Margin Tax — that applies to most business entities. Understanding how LLC versus S corp treatment interacts with the franchise tax is part of a complete Texas-specific analysis.
What the Decision Process Should Look Like
The LLC vs S corp decision is not a checkbox exercise. It’s a financial model.
The right approach starts with actual numbers: current net profit, projected growth, owner compensation needs, administrative capacity, and long-term plans for the business. Both scenarios get modeled. The tax savings get quantified. The compliance costs get factored in. And the reasonable compensation question gets answered before the election is filed.
A tax attorney who also holds a CPA license can do the modeling, set the salary correctly, file the election properly, and keep the strategy defensible if the IRS ever looks at it.
Frequently Asked Questions About LLC vs S Corp Tax Implications
What is the main tax difference between an LLC and an S corp?
A default LLC passes all profits through to the owner’s personal return, and the owner pays self-employment tax on the full net profit. With S corp treatment, the owner pays self-employment tax only on the W-2 salary portion — distributions avoid Social Security and Medicare taxes.
Does Texas have S corps?
Texas doesn’t have a separate S corp entity. A Texas LLC can elect federal S corp tax treatment by filing Form 2553 with the IRS. The business remains an LLC under Texas law — only its federal tax classification changes.
When does S corp election make sense financially?
Most advisors look for net profits of at least $40,000 to $50,000 before the election makes economic sense. Below that, the administrative costs often outweigh the tax savings.
What does reasonable compensation mean for S corp owners?
An S corp owner who works in the business must pay themselves a salary that reflects what the market would pay for those same services. The IRS audits unreasonably low salaries aggressively.
Can a single-member LLC elect S corp status?
Yes. A single-member LLC that meets the eligibility requirements can file Form 2553 to elect S corp treatment. The owner becomes both the sole shareholder and a W-2 employee of the company.
What are the main restrictions on S corp eligibility?
S corps cannot have more than 100 shareholders, all shareholders must be U.S. citizens or permanent residents, and only one class of stock is permitted.
What happens if the IRS reclassifies S corp distributions as wages?
The IRS can assess back payroll taxes on reclassified amounts, plus interest and penalties. In serious cases, this can eliminate all of the tax savings the S corp election was designed to produce.
How does Texas franchise tax affect the LLC vs S corp decision?
Texas franchise tax applies to most entities regardless of federal tax classification. In most cases the franchise tax is not the deciding factor — the federal self-employment tax savings drive the analysis.
