137: Financial Mistakes - Tax Planning Gaps

In this episode of the Dental Boardroom Podcast, host Wes Read, CPA and financial advisor at Practice CFO continues his series on common financial mistakes dentists make, this time focusing on tax planning gaps. Wes explains why many dental practice owners unknowingly overpay taxes and how poor tax planning often results from weak cash flow management, rather than bad intentions.This episode breaks down complex tax concepts into practical insights, helping dentists understand how smarter planning throughout the year, not just at tax time, can lead to tens of thousands of dollars in savings annually and faster financial independence.Key Notes:1. Tax Planning Is Not a Once-a-Year ActivityMany dentists believe tax planning is handled solely by their CPA at year-end.Real tax planning happens throughout the year, tied directly to business decisions.Waiting until December often means it’s already too late to reduce taxes effectively.2. Tax Planning Is a Subset of Cash Flow PlanningTaxes cannot be optimized in isolation.Every dollar flowing through the practice revenue, expenses, payroll, debt, and savings affects tax outcomes.Smart tax strategies must consider current and future cash flow, not just immediate deductions.3. Common Tax Planning Gaps Dentists MakeMissing legitimate deductions (leaving money on the table).Buying equipment just for a tax write-off without considering long-term loan payments.Poor timing of depreciation and capital purchases.Not coordinating payroll, distributions, and retirement planning.4. Understanding S Corporations vs. Sole ProprietorshipsBeing an S Corp does not automatically mean you’re saving taxes.S Corps come with higher administrative costs, so the tax benefits must outweigh them.In general:Under ~$150k income → Sole proprietor may make more sense.$180k–$200k+ profit → S Corp usually becomes beneficial.5. Reasonable Compensation: The Biggest Tax LeverAs an S Corp owner, you pay yourself in two ways:W-2 wages (subject to payroll/FICA taxes)Distributions (not subject to FICA)Paying too little W-2 can trigger IRS penalties.Paying too much W-2 can unnecessarily increase payroll taxes.Finding the right balance is critical to staying compliant and tax-efficient.6. Payroll Taxes vs. Income TaxesFICA taxes apply only to W-2 wages.Distributions avoid FICA but are still considered taxable income.Higher W-2 wages allow for:Larger retirement plan contributionsBigger income tax deductionsStrategy depends on whether you’re prioritizing tax savings now or retirement funding for the future.7. Retirement Plans Must Match Cash FlowCookie-cutter 401(k) plans often fail dentists.Retirement plans should be designed based on:Practice profitabilityOwner age vs. staff ageAbility to consistently fund contributionsPoorly planned retirement strategies can increase complexity without meaningful tax benefits.8. Financial Independence Requires DisciplineOverspending today steals from your future self.Automating savings and planning intentionally creates long-term freedom.Proper tax planning can realistically save:$30,000–$50,000 per year for well-run dental practicesEven more for higher earners with strong cash flow
