This question comes up constantly once a practice starts generating real, consistent profit, and the honest answer depends on your specific numbers, not a blanket rule that applies to every owner at the same revenue level.

Here's the core mechanic. As a sole proprietor or single-member LLC, all of your practice profit is subject to self-employment tax, currently 15.3 percent, on top of regular income tax. As an S-corp, you pay yourself a reasonable salary through payroll, which is subject to that same 15.3 percent, but additional profit distributed to you as the owner isn't subject to self-employment tax. That difference is where the savings come from.

The catch is the word "reasonable" in reasonable salary. The IRS expects a salary that reflects what your clinical work would actually cost to replace, not an artificially low number designed purely to shift more income into the tax-advantaged distribution category. For a solo practitioner, this generally means benchmarking against what it would cost to hire an associate chiropractor to do the clinical work you're doing yourself. Get this wrong and you're creating real audit exposure rather than genuine savings.

S-corp status also isn't free to maintain. You're now running actual payroll, which means payroll processing costs and payroll tax filings that didn't exist before. There's additional tax return complexity, generally requiring a separate business return. For a practice with modest profit, those added costs can eat up most or all of the potential tax savings, which is exactly why this isn't a decision that makes sense at every stage.

As a general guideline, the math tends to start favoring S-corp status once net profit is consistently well above a reasonable clinical salary, often somewhere in the range of $60,000 to $80,000 in profit beyond that salary, though your specific numbers matter more than any rule of thumb.

This isn't a decision to make off a general guideline alone. It requires running your actual numbers, both the tax savings and the added administrative cost, side by side.
