S-corp Tax Savings for Dentist in CO

Running an S corporation can lower self-employment taxes by splitting pay into W-2 salary and distributions, but the IRS expects that salary to be reasonable for the work performed. This guide gives a practical, planning-first framework for a Dentist in Colorado, plus the official sources your CPA will want to see.

Last reviewed: January 15, 2026.

Key takeaways

• The IRS expects shareholder-employees to take reasonable wages before distributions.
• Reasonable compensation is fact-specific: role, hours, revenue drivers, and comparable market pay matter.
• Use a documented range (not a single number) that your CPA can defend.

State tax snapshot

• Colorado S corporations file a Partnership and S Corporation Income Tax Return (DR 0106) for any year they do business in Colorado. (https://tax.colorado.gov/business-organizational-structure)
• If a corporation is an S corporation for federal income tax purposes, it is an S corporation for Colorado income tax purposes, and Colorado does not tax S-corp income at the entity level. (https://tax.colorado.gov/business-organizational-structure)
• For tax years 2022 and later, the Colorado individual income tax rate is 4.4%. (https://tax.colorado.gov/individual-income-tax-guide)

Role & revenue drivers

Dentists typically anchor revenue through chairside procedures while overseeing hygienists and practice operations. Procedure mix and schedule intensity drive comp expectations.

State + profession context

Dentist owners balance chair time with leadership of the hygiene team, scheduling, and equipment oversight. Procedure mix and case complexity drive revenue more than patient count alone, so the role blends clinical production and practice management. If you run multiple operatories or supervise associates, the management component of compensation rises quickly. Use the OEWS wage range as an anchor, then adjust for chair time, team oversight, and operational responsibilities. The goal isn’t a perfect number; it’s a defensible range your CPA can validate from the facts you keep on file. Documenting time allocation and responsibilities is often the deciding factor.

Compensation benchmark (SOC)

• SOC code: 29-1021 (Dentists, General).
• BLS OEWS (May 2024 release) annual median wage in Colorado: $136,260; 25th–75th percentile range: $84,990–$181,010. (https://data.bls.gov/oes/)

Note: OEWS May 2024 was released on April 2, 2025. (https://www.bls.gov/oes/update.htm)

What "reasonable compensation" means

Reasonable compensation is the wage you would pay someone else to do your job under similar conditions. The IRS looks at duties, experience, time spent, and what comparable roles earn, not a fixed percentage of profit. Use multiple data points to defend a range, not a single number.

A clean framework

1. Define the role. Capture what you actually do: chair time, hygiene team oversight, lab coordination, and practice operations.

2. Benchmark a range. Use BLS occupational wage data plus any industry surveys or local comps your CPA trusts. Focus on state-level data where possible.

3. Model the split. Pay the reasonable wage as W-2 salary; treat the remaining profit as distributions only after the wage is defensible.

4. Document the rationale. Keep your notes, sources, and calculations with the tax file so your CPA can defend the position.

Example scenario

Example: A Colorado dentist with heavy chair time plus oversight of a hygiene team can benchmark a range that reflects both clinical output and managerial responsibility. Track chair hours versus leadership time and keep that breakdown with your comp file.

FAQ

Do I need a separate state S election in Colorado? Colorado recognizes the federal S‑corporation election for state income tax purposes, but you still need to meet Colorado registration and DR 0106 filing requirements. Confirm details with your CPA.

Should I use national or Colorado wage data? Colorado or local wage data is more defensible when available; the OEWS database provides state‑level benchmarks you can cite. (https://data.bls.gov/oes/)

What documents should I keep? Keep a role description, time allocation notes, and compensation benchmarks; the IRS focuses on duties and comparable wages when evaluating reasonableness.
