S-Corp vs LLC is one of the first structural decisions a dental practice owner faces, and it is one of the most consequential for your tax bill. The two are often talked about as if they are competing options, but the reality is more nuanced, and getting it right can save a Virginia practice real money every year. Here is how S-Corp vs LLC actually compares for dentists.
First, they are not the same kind of thing
An LLC is a legal business structure; an S-Corp is a tax election. That distinction matters, because an LLC can actually choose to be taxed as an S-Corp. So the real question is usually not “LLC or S-Corp,” but “should my practice elect S-Corp taxation?” The IRS overview of S corporations lays out the basic rules and eligibility.
S-Corp vs LLC: how they actually compare
A standard LLC’s profits are all subject to self-employment tax. With an S-Corp election, you pay yourself a reasonable salary (subject to payroll taxes) and take remaining profits as distributions, which are not subject to self-employment tax. For a profitable dental practice, that difference can be substantial. The trade-off is more administration: payroll, a separate return, and the requirement to pay yourself a genuinely reasonable salary.
When the S-Corp election makes sense
The election tends to pay off once a practice’s profit is high enough that the self-employment tax savings comfortably outweigh the added payroll and filing costs. Many single-owner dental practices cross that line, but not all, and the “reasonable salary” requirement means you cannot simply zero out your wages to dodge payroll tax. This is exactly the kind of numbers question worth running with your accountant before you file the election.
Don’t forget the ongoing work
An S-Corp adds payroll and a separate tax return to your year, which makes clean books more important, not less. If you are setting up or tightening your systems, our guides to the first 90 days of dental practice bookkeeping and quarterly estimated taxes pair naturally with this decision. And whichever way you go, make sure you are capturing every deduction, our list of dental practice tax deductions owners miss is a good check.
Let’s run your numbers
The S-Corp vs LLC decision is not one-size-fits-all; it depends on your practice’s profit, your salary, and your appetite for a bit more paperwork. At Quantum, we help Virginia dental practices run the actual math and make the election only when it genuinely pays.
