Selling Your Dental Practice in Washington — Defer the Capital Gain

This page covers the dental practice sale in Washington specifically. For the general framework see the dental practice guide or the §453 SIS basics.

The math — $4M sale, 80% goodwill, Washington 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 Washington's bracket structure.

Washington-specific tax wrinkle

Washington's 7% capital-gains tax applies only to long-term gains above $250K per year. §453 spreading can drop you below the $250K threshold each year, eliminating WA tax entirely.

The Washington dental practice market

Washington has ~5,500 dentists under RCW 18.32 ownership rules. Seattle tech-corridor specialty practices (cosmetic, orthodontic) command 110-125% of revenue — among the highest in the country. WA's 7% capital gains tax kicks in only above $250K/year of gain — §453 spreading can drop annual gain below the threshold each year, eliminating WA state tax entirely on the deferred portion. Heartland, Aspen, and several Pacific NW DSOs (Smile Brands NW, Forest Smiles) are active.

Washington buyers and consolidators

The active acquirers buying dental practices in Washington: 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 Washington seller

• $1.5M+ sale price (carrier minimums on the §453-deferred portion)
• Long hold with meaningful gain (where Washington's 7% (gains over $250K) state rate stacks on federal)
• Sophisticated buyer whose counsel will paper the §453 assignment
• Washington resident at closing (state residency matters for the state-tax piece)

Frequently asked

Q: I'm a Washington 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 Washington before closing. Does that change anything? A: Maybe. Washington'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.

Educational. Not tax or legal advice. Washington tax treatment of §453 generally follows federal — confirm with your CPA.
