Running a dental practice in Houston means wearing two hats at once clinician and business owner. Most dentists are exceptionally good at the first one. The second one, particularly when it comes to taxes and financial strategy, is where significant money gets left on the table year after year.
The tax mistakes dental practice owners make aren’t unusual they’re consistent, predictable, and in almost every case, entirely fixable. At Riley & Company, we work with healthcare and dental practices across Houston, The Woodlands, Northwest Houston, and Cypress, and we see the same patterns come up again and again.
Here are the most costly tax mistakes dental practices make and exactly how a specialized CPA addresses them.
Many dental practice owners are still operating as sole proprietors or single-member LLCs years past the point where that structure made financial sense. As practice revenue grows, this becomes one of the most expensive structural mistakes a dentist can make.
The issue is self-employment tax. At a flat 15.3% on net earnings, it applies to every dollar of profit for sole proprietors and default LLCs. An S-Corp election changes that equation significantly practice owners pay themselves a reasonable salary (subject to payroll tax) and take additional profit as distributions, which are not subject to self-employment tax.
For a dental practice generating $300,000 in net profit, the difference between a default LLC and a properly structured S-Corp can represent $15,000–$25,000 in annual tax savings. That’s a structural decision not a deduction and it requires proactive planning to implement correctly.
If you haven’t had a conversation with your CPA about entity structure recently, it’s worth having now. Our tax planning services include a full review of your current structure and a modeled comparison of what a change would mean for your specific situation.
Dental practices are equipment-intensive businesses chairs, imaging systems, CAD/CAM technology, sterilization units, laser equipment. Each of these purchases represents a significant deduction opportunity that many practice owners don’t fully capture.
Under Section 179 of the IRS tax code, businesses can immediately deduct the full cost of qualifying equipment placed in service during the tax year, rather than depreciating it over several years. In 2026, the Section 179 deduction limit remains generous and for dental practices investing in new technology, this can translate into substantial first-year deductions.
Bonus depreciation is an additional tool that can layer on top of Section 179 for qualifying property. The rules around both have evolved in recent years, and the interaction between them requires careful planning to maximize the benefit.
The mistake most dental practices make isn’t failing to claim these deductions it’s failing to time equipment purchases strategically. A piece of equipment purchased in December versus January lands in a completely different tax year. That timing decision, made with your year-to-date income projections in hand, can dramatically affect your tax liability.
Retirement contributions are one of the most powerful tax reduction tools available to dental practice owners and one of the most underused. Every dollar contributed to a qualifying retirement plan reduces your taxable income dollar-for-dollar.
The options available to dental practice owners are substantial:
According to the IRS guidelines on retirement plans for self-employed individuals, these plans not only reduce current-year taxes but build long-term wealth in a tax-advantaged structure.
Many dental practice owners either haven’t established a retirement plan at all, or are using the wrong plan type for their income level. A CPA who understands dental practice finances can model which plan structure produces the most tax efficiency at your specific revenue level.
The question of whether to bring on an associate as an employee or an independent contractor is one of the most tax-consequential decisions a dental practice owner makes and one of the most frequently mishandled.
The IRS has specific criteria for determining worker classification, and misclassifying an employee as an independent contractor exposes the practice to back payroll taxes, penalties, and interest. In the dental industry, where the working relationship between a practice owner and associate is often long-term and structured, the IRS typically expects these arrangements to be treated as employment.
Beyond classification, how associate compensation is structured base salary, production bonuses, benefits has significant payroll tax and deduction implications that should be reviewed with a CPA before any associate agreement is signed.
The QBI deduction allows eligible pass-through business owners to deduct up to 20% of qualified business income on their personal tax return. For dental practices structured as sole proprietorships, partnerships, or S-Corps, this can represent a significant reduction in taxable income.
However, dental practices are classified as Specified Service Trades or Businesses (SSTBs) under the tax code which means the QBI deduction phases out as income rises above certain thresholds. In 2026, those thresholds are adjusted for inflation, making it essential to review your eligibility annually rather than assuming the deduction is or isn’t available.
This is an area where proactive planning pays off. Strategies like adjusting owner compensation, timing income and deductions, and structuring the practice correctly can affect QBI eligibility in meaningful ways but only if those decisions are made before the year closes.
Perhaps the most systemic mistake dental practices make isn’t a single error it’s the absence of ongoing financial oversight. Many practice owners see their CPA once a year at tax time, receive a return, and repeat the cycle. By the time that annual conversation happens, the year is over and most planning opportunities have expired.
The dental practices with the strongest financial positions are almost never the ones with the highest revenue they’re the ones with consistent, proactive financial management throughout the year. That means quarterly estimated tax reviews, mid-year planning conversations, ongoing bookkeeping that keeps records current, and a CPA who understands the dental industry well enough to flag opportunities as they arise.
Our Part-Time CFO Services are specifically designed for practices at this stage bringing CFO-level financial oversight and strategic guidance without the cost of a full-time hire.
If you haven’t had a formal entity structure review in the past two years or if your practice revenue has grown significantly since you set up your entity it’s time for one. The right structure at $150,000 in revenue is often not the right structure at $400,000.
Timing depends on your projected year-end income and tax liability. In some cases, buying before December 31 maximizes your current-year deduction. In others, deferring to January produces a better outcome. This decision should be made with your year-to-date financials in hand ideally in October or November.
Yes, CE courses, professional licenses, state dental association dues, and similar expenses are deductible business expenses for dental practice owners. Many practices undertrack these expenses and miss legitimate deductions.
Dental practices have financial nuances that general accountants frequently miss insurance reimbursement timing, equipment-heavy depreciation schedules, associate compensation structures, SSTB treatment of the QBI deduction. Working with a CPA who understands the dental industry isn’t just convenient it directly affects how much you pay in taxes every year.
