Houston business owners evaluating their entity structure now have a detailed resource to inform the decision. Mixon Tax Law, a Houston boutique tax law firm specializing in business tax and IRS representation, has published a comprehensive guide comparing the LLC vs S corp tax implications for Texas small business owners at every stage of business development.
The guide addresses a foundational misconception that shapes how most business owners approach the decision. An S corp is not a separate legal entity — it is a federal tax classification. A Texas LLC can elect to be taxed as an S corp by filing IRS Form 2553, retaining its LLC structure under Texas law while accessing different federal tax treatment. Most Houston business owners who say they want an S corp are, in practice, forming an LLC and making a tax election.
The primary tax advantage of S corp treatment is a reduction in self-employment tax exposure. Under default LLC taxation, all net profits are subject to self-employment tax — currently 15.3 percent on earnings up to the Social Security wage base, and 2.9 percent above it. When a business owner elects S corp treatment, income is split between a W-2 salary and shareholder distributions. Payroll taxes apply only to the salary portion, not to distributions, which can produce annual savings of $10,000 or more for businesses generating substantial net profit.
"The structure can absolutely produce real savings," said Phillip Mixon, JD/CPA and principal attorney at Mixon Tax Law. "But those savings only materialize if the salary is set correctly. The most common mistake we see is business owners who heard about the strategy, set up the election, and then paid themselves next to nothing in salary to maximize distributions. That approach creates more audit exposure than it eliminates."
The reasonable compensation requirement is the central compliance issue in any S corp election. IRS regulations require that an S corp owner who actively works in the business receive a salary that reflects what the market would pay for those services in an arm's-length transaction. When salaries are set too low, the IRS can reclassify distributions as wages and assess back payroll taxes, interest, and penalties — potentially eliminating the full benefit of the election. The IRS has consistently identified S corp compensation as a priority audit area for small business returns.
The guide also outlines structural restrictions that apply to S corps and that business owners should evaluate before filing. 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. Businesses planning to raise outside capital or structure for acquisition may find these restrictions limit their options as the company scales.
From a Texas-specific perspective, the absence of a state income tax removes one of the common drivers of S corp elections in other states. In California or New York, S corp status can also reduce state tax exposure. In Texas, the federal self-employment tax savings are the primary financial justification — which makes the reasonable compensation figure the decisive variable in any structure decision.
Phillip Mixon's dual CPA and JD credentials allow the firm to address both the accounting analysis and the legal filing within a single engagement. The complete guide, including worked examples and the conditions under which the election makes financial sense, is available through Mixon Tax Law's business tax attorney services resource library.
Houston area business owners considering S corp election or entity formation are encouraged to review the guide and consult with the firm directly before filing Form 2553.
