Selling Your Dental Practice in Arizona — Defer the Capital Gain
If you're selling a dental practice in Arizona, the tax math depends heavily on your state's capital-gains treatment. Arizona's top LTCG rate is 2.5% — combined with federal 23.8% (20% LTCG + 3.8% NIIT), a lump-sum sale gives back 26.3% of your gain in year one. IRC §453 structured installment sale spreads the gain across the payment schedule, keeping you in lower brackets each year.

This page covers the dental practice sale in Arizona specifically. For the general framework see the dental practice guide or the §453 SIS basics.
The math — $4M sale, 80% goodwill, Arizona resident
The §453 spread captures roughly the difference between these two numbers — typically 8-12 percentage points of the gain depending on your specific deal economics and Arizona's bracket structure.
Arizona-specific tax wrinkle
Arizona's flat 2.5% rate is among the lowest in the country. §453 benefit is mostly federal-bracket-smoothing + NIIT-threshold management.
The Arizona dental practice market
Arizona has ~5,000 dentists with strong retirement-state cosmetic demand. Scottsdale and Tucson command premium valuations (95-110% of revenue); rural AZ trades at 75-85%. Aspen Dental's Phoenix-area presence is heavy. AZ's flat 2.5% state tax means §453 benefit is mostly federal-bracket smoothing — but high-EBITDA practices ($1M+) still see meaningful NIIT-threshold management benefit from spreading.
Arizona buyers and consolidators
The active acquirers buying dental practices in Arizona: Heartland Dental, Pacific Dental Services, Aspen Dental, MB2 Dental, Smile Brands, North American Dental Group. These institutional buyers' M&A counsel are familiar with the §453 mechanic — papering the assignment at closing is standard.
Dental Practice-specific §453 wrinkle (applies in every state)
Most DSO deals are 80%+ goodwill (self-created, $0 basis) — exactly what §453 was built for. Equipment §1245 recapture (CEREC, CBCT, scanners) hits year one regardless.
When this fits a Arizona seller
- $1.5M+ sale price (carrier minimums on the §453-deferred portion)
- Long hold with meaningful gain (where Arizona's 2.5% state rate stacks on federal)
- Sophisticated buyer whose counsel will paper the §453 assignment
- Arizona resident at closing (state residency matters for the state-tax piece)

Frequently asked
Q: I'm a Arizona resident but the property is in another state. Where's the tax? A: Generally the gain is sourced to where the property sits (real estate) or where the seller resides (intangibles). Talk to your CPA on multi-state allocation; §453 mechanic works the same.
Q: I'm planning to move out of Arizona before closing. Does that change anything? A: Maybe. Arizona's residency tests differ — California's exit tests are aggressive; other states less so. Talk to a state-tax specialist before timing the move.
Q: Does the §453 mechanic differ state-to-state? A: No. §453 is federal. State tax rates determine the size of the savings; the mechanic is identical.
