How a Semi-Retired Dentist Turned a Practice Sale Into $20K–$35K in Annual Tax Savings

The Challenge

Selling a dental practice does not simplify a tax return, it multiplies it. This client had gone from one income stream to three at once: clinical income through an S-Corp for the four days a month he still works, rent from the office building he kept and now leases to the practice's new owner, and installment payments from the sale itself. Each carries a different character, a different timing profile, and a different set of planning levers.

The structure was sound. The coordination between the pieces had not caught up to it.

• Clinical compensation still reflected a full-time practice owner rather than a part-time clinical role
• Retirement contribution capacity was going largely unused
• California pass-through entity tax was being handled without a timing plan
• The building was generating income with no deliberate plan attached to it
• Household-level opportunities sat outside the business return entirely
• Bookkeeping was informal, which limited how defensible any of it would be under scrutiny

Left alone, the arrangement would have kept working and kept costing. The income was arriving regardless. The question was how much of it needed to.

The Gelt Strategic Approach

Gelt started by mapping all three income streams and the household together, then sequenced the strategies so each one supported the next rather than competing with it.

S-Corp Compensation Calibration

Clinical compensation was reset to match the actual scope of the client's remaining role. That one adjustment reduced payroll tax exposure and reset the ceiling for every retirement strategy that followed.

Retirement Contribution Coordination

Gelt modeled retirement capacity across both spouses and identified meaningful shelter available against high-bracket income, with a multi-year plan for how contributions should shift as the sale payments wind down.

PTET Payment Timing

California pass-through entity tax was brought onto a deliberate timing plan. Projected to contribute roughly $5K in annual federal benefit.

Building and Home-Use Planning

The office building's rental income was folded into a coordinated plan alongside an Augusta rule arrangement, giving the household a defensible deduction it was not previously claiming.

Family Payroll

Legitimate work performed by the client's children was brought onto the business payroll, projected at $8K to $10K in annual household benefit.

Charitable and Insurance Positioning

Health insurance was routed through payroll for correct treatment, and a donor-advised fund was positioned to make the household's giving work harder against the highest-income years.

Results & Implementation Roadmap

Immediate (0-60 Days)

• Implement payroll adjustments for both spouses
• Correct California PTET payment timing
• Bring the children onto payroll for work performed
• Route health insurance through payroll

90-120 Days

• Finalize retirement contribution decisions for the year
• Stand up professional bookkeeping for the S-Corp and the building
• Formalize Augusta rule documentation
• Coordinate directly with the household's wealth manager

Ongoing Strategy

• Revisit sale payment timing against bracket projections each year
• Evaluate conversion opportunities as installment income tapers
• Time charitable funding to the highest-income year
• Maintain audit-ready records across the household strategies

Taken together, the coordinated plan is projected to deliver $20K to $35K in annual tax savings, with additional value expected as installment income tapers and conversion opportunities open up.

"Selling the practice was supposed to be the simple part. Gelt was the first group to look at the clinical income, the building, and the sale payments as one picture instead of three separate problems."

– Gregory Whitfield, DDS, Former Owner, Lakeshore Family Dental

Conclusion

A practice sale is not a finish line for tax planning, it is the moment the planning gets more interesting. Income that used to arrive through one entity now arrives through three, and each one responds to different levers at different times.

What this case demonstrates is the value of sequencing. Calibrating compensation first made the retirement strategy possible. Getting the state tax timing right made the credit real. None of the individual moves were exotic. Coordinating them was the work.
