For many service professionals, business success brings an unexpected problem: a growing tax bill. This case study walks through how we guided a thriving private practice owner through a strategic transition to an S Corporation and what that shift meant for her bottom line.
A successful and growing private therapy practice owner, operating as a sole proprietor with a mix of subcontractors and employees. The practice was profitable and expanding, but the business structure hadn’t kept pace with its growth.
The client was excellent at her work. The financial side of the practice was a different story.
As a sole proprietor, she was paying self-employment tax on every dollar of profit — roughly 15.3% on top of her income tax. There was no formal system for tracking or reimbursing business expenses. Strategies available to corporate entities were completely off the table. And without a CPA partner who understood the nuances of her structure, she had no clear picture of what she was leaving behind every tax year.
She needed more than a tax preparer. She needed someone who could build a financial framework that matched the level of success she had already achieved.
Before recommending any changes, we started with the numbers.
Cost-benefit analysis first. An S Corp election comes with real administrative costs: payroll processing, additional bookkeeping, and annual filings. We ran a detailed analysis to confirm that the projected tax savings would meaningfully outweigh those new costs. For this client, they did. It doesn’t always, and location and state matters, so this step is important.
A defensible salary, not a guess. One of the most scrutinized aspects of an S Corp is the owner’s salary. Pay yourself too little and the IRS takes notice. We conducted a formal reasonable compensation study using third-party data to substantiate her salary; the kind of documentation that holds up if the IRS ever asks questions.
An accountable plan for real expenses. We established a formal accountable plan for the practice, allowing the business to properly reimburse the owner for her business use of a personal vehicle and home office. These were real, legitimate expenses she had been absorbing personally. Structuring them correctly turned them into business deductions.
The Augusta Rule. We are currently implementing a strategy under Section 280A, sometimes called the Augusta Rule. This allows the client to rent her home to the S Corp for up to 14 days per year — in this case, for quarterly board meetings — creating a tax-free payment to the owner and a legitimate deduction for the corporation.
The transition to an S Corporation fundamentally changed this client’s financial picture.
She is projected to save over $8,000 annually in taxes — savings that compound year over year as her practice continues to grow.
Beyond the number, what changed is her relationship to her own business finances. She moved from a sole proprietorship with no formal structure to a sophisticated business entity with a defensible salary, a documented expense reimbursement process, and advanced tax strategies actively in place.
She can now focus entirely on her clients, knowing her financial foundation is solid, compliant, and working in her favor.
If you’re a therapist, consultant, physician, attorney, or any other service professional operating as a sole proprietor or single-member LLC, this scenario is more common than you might think.
The S Corp election isn’t right for everyone. It makes the most sense when your net profit reaches a level where the self-employment tax savings outweigh the added administrative costs generally at least when there is $50,000 or more in annual profit, though every situation is different.
The strategies used here: reasonable compensation studies, accountable plans, and Section 280A, are legitimate, well-documented tools. They aren’t loopholes. They’re the financial framework that incorporated businesses have access to, and that sole proprietors are missing out on every year they delay the conversation.
A business structure that made sense when you were just starting out may be costing you thousands of dollars a year as your practice grows. The right CPA partner doesn’t just file your return — they look at the full picture and help you build a structure that works as hard as you do.
If you’re a service professional wondering whether an S Corp election makes sense for your practice, that conversation starts with a simple cost-benefit analysis. The math either works or it doesn’t — and knowing the answer either way puts you in a better position than not asking.
