California dental owner guide
Dental Practice Owner Real Estate Tax Planning Guide
A dental-practice owner should coordinate practice accounting, business and individual tax returns, rental-property records, debt, ownership and transaction timing before buying, refinancing or selling real estate. The real-estate decision should not be analyzed separately from the dentist’s practice cash flow and tax picture.
What should real estate tax planning cover for a dental-practice owner?
Real estate tax planning for a dental-practice owner should connect the property’s use, legal ownership, financing, rental activity, depreciation, passive-loss position, expected holding period and exit plan with the dental practice and the owner’s individual return. A property LLC, dental corporation and individual owner may have separate books and returns, but the tax and cash-flow decisions still interact.
The CPA should know whether the property is a dental office, unrelated rental, mixed-use building, former residence, short-term rental or property held for sale. That classification affects reporting, depreciation, passive-activity treatment and the records required.
As of August 2026
Coordinate the practice, property and individual return.
- Keep separate books and supporting records for every property and ownership entity.
- Model debt service, taxes, reserves and practice occupancy cost before closing.
- Review depreciation, passive losses and self-rental treatment before relying on projected deductions.
- Plan sales, exchanges and California withholding before signing the contract.
Should a dentist own the dental office separately from the practice?
Separate ownership may isolate the dental operating business from the real-estate investment and allow a written lease between the property owner and practice. It does not automatically produce tax savings or solve liability, financing, professional-entity, partner or estate-planning issues.
| Issue | Review before purchase | Evidence needed |
|---|---|---|
| Ownership | Individual, disregarded LLC, partnership or other permitted structure | Operating agreements, title and ownership percentages |
| Lease | Market rent, term, escalations, expenses and assignment | Written lease and comparable support |
| Financing | Borrower, guarantees, covenants and debt-service capacity | Loan proposal and amortization |
| Tax reporting | Income, expenses, depreciation and related-party treatment | Books, returns and depreciation schedules |
| Exit | Sell together, retain and lease, or transfer separately | Practice succession and property plan |
What records should be maintained for rental real estate?
Each property and entity should have separate income and expense records, reconciled bank and loan balances, closing documents, leases, property-tax records, improvement invoices and a current depreciation schedule. The records should distinguish repairs from capital improvements and identify personal use, vacancy, tenant deposits and related-party transactions.
IRS Publication 527 explains that rental income generally must be reported and that common rental expenses may include maintenance, insurance, taxes, interest, management fees and depreciation. The publication also requires expenses to be divided when property has both rental and personal use.
A loss on paper may not be deductible now
Can a dental-practice owner deduct rental real estate losses?
Rental activity is generally passive even when the owner participates, unless an exception applies. The current deduction can depend on active participation, adjusted gross income, at-risk limits, real-estate-professional status, material participation and prior suspended losses.
Property rented to a dental practice in which the owner materially participates can also trigger the self-rental rule. IRS Publication 925 states that net rental income from property rented to a nonpassive business activity in which the taxpayer materially participates is treated as nonpassive income. Transaction-specific review is required before projecting how rent or losses will affect the individual return.
How should depreciation and improvements be coordinated?
Land is not depreciated. The depreciable basis of a building and other qualifying property must be supported by acquisition records and placed-in-service dates. Repairs may be currently deductible when the rules allow, while improvements generally must be capitalized and recovered over the applicable period.
| Record | Tax question | Later consequence |
|---|---|---|
| Closing statement and allocation | How much basis belongs to land, building and other property? | Depreciation and gain computation |
| Placed-in-service evidence | When was the property ready and available for its intended use? | Start of depreciation |
| Repair invoice | Does the cost maintain the property or improve it? | Current deduction or capitalization |
| Improvement schedule | What separate assets and recovery periods apply? | Annual depreciation and sale reporting |
| Prior depreciation | Was the allowable depreciation recorded correctly? | Adjusted basis and potential recapture |
What should a dentist review before buying, refinancing or selling real estate?
Before a purchase, compare the cash contribution, financing, reserves, occupancy economics, ownership and projected after-tax cash flow. Before refinancing, trace the use of proceeds, compare the new debt terms and confirm that the practice and property can support the payments. Before a sale, calculate adjusted basis, depreciation effects, selling costs, federal and California tax, withholding, debt payoff and available after-tax proceeds.
Loan proceeds from a true borrowing generally are not income because they must be repaid, but interest deductions depend on the use of proceeds and applicable limits. A refinance should therefore be reviewed as both a cash-flow decision and a tax-tracing decision.
Plan before the sale closes
Can a dentist use a Section 1031 exchange?
A qualifying Section 1031 exchange may defer gain when real property held for business or investment is exchanged for qualifying real property and all requirements are met. Section 1031 does not apply merely because sale proceeds are reinvested later.
The taxpayer cannot take actual or constructive receipt of the proceeds outside an applicable safe harbor. In a deferred exchange, replacement property generally must be identified within 45 days and received by the earlier of 180 days after the transfer or the due date, including extensions, of the return for the transfer year. The qualified intermediary and tax review should be arranged before closing.
How does California real estate withholding affect the sale?
California real estate withholding is a prepayment of income tax connected with a California real-property transfer, not the final tax calculation. Form 593 is used for California real estate withholding and exemptions. The seller should provide required information to escrow before closing and reconcile the withholding to the applicable California return.
The transaction model should separately show estimated federal tax, estimated California tax, withholding, debt payoff, closing costs and net cash. Withholding can create a cash-flow mismatch when it differs from the final California liability.
Which services belong in the engagement scope?
| Service | Typical work | Separate project trigger |
|---|---|---|
| Monthly property accounting | Transactions, reconciliations, loans and property reports | Historical cleanup or missing records |
| Tax preparation | Property activity on individual or entity returns | Delinquent or amended returns |
| Year-round tax planning | Projections, estimates, depreciation and ownership coordination | New property or material use change |
| Transaction planning | Purchase, refinance, sale or exchange model | Defined transaction and deadline |
| Legal and valuation work | Performed by the appropriate attorney or valuation professional | Entity documents, title, lease or appraisal |
Frequently asked questions about dental-owner real estate tax planning
Should a dentist hold real estate in the dental-practice entity?
Not automatically. Review liability, financing, professional-entity restrictions, lease terms, tax reporting, co-owners, estate planning and exit goals before title is taken.
Can a dental-practice owner deduct rental real estate losses?
Rental losses are generally subject to passive-activity and at-risk rules. The result depends on participation, income, property use, ownership, prior suspended losses and whether a self-rental or real-estate-professional rule applies.
Is refinancing rental property taxable?
Loan proceeds from a true borrowing generally are not income because they must be repaid, but interest deductibility depends on how the proceeds are used and other limitations. Model the debt terms, cash flow and tax tracing before closing.
Can a dentist exchange rental property under Section 1031?
A qualifying exchange may defer gain on real property held for business or investment when all requirements are met. The taxpayer cannot take actual or constructive receipt of the sale proceeds outside an applicable safe harbor.
Does California real estate withholding equal the final tax?
No. California real estate withholding is a prepayment. The final California tax is determined on the applicable income-tax return.
What records should a dentist keep for each rental property?
Maintain separate income and expense records, bank and loan statements, closing documents, improvement invoices, depreciation schedules, leases, property-tax records and documentation of personal or business use for each property and entity.
