The indicated tax treatment applies only to transactions deemed to reflect a purchase of the equipment or a capitalized lease purchase transaction. Please consult your tax advisor to determine the tax ramifications of acquiring equipment or software for your business.

How It Works

It's quite simple. The tax code indicates a new dental chair should last five years. As such, you can deduct one-fifth of the cost annually on your return until the cost has been fully depreciated. Easy enough. But that's not all...

The same tax code allows for a full deduction in the current year within code Section 179. For example, if you purchased $300,000 in equipment and placed it into service in a single year, you would take the full deduction ($300,000) immediately.

Section 179 equipment deductions


Any dental practices that purchase, finance or lease less than $2 million in new or used equipment for their business during the previous tax year should qualify for the Section 179 deduction.


Bonus depreciation is a deduction that is allowed on equipment that has not been recognized under Section 179 — any amount over $500,000 and below the $2 million threshold. How much can be deducted? Half of the cost to acquire.

Three Golden Rules of Section 179

According to Trent Watrous, a dental-specific CPA in Nashville, TN, there are three golden rules to keep in mind when considering the IRS Section 179 Tax Deduction.


The deduction is allowed only in the year that the asset is “placed into service.” This means the year in which the equipment is ready for use, not the year in which the equipment is purchased.


Section 179 applies to personal property, such as equipment and technology, and potentially leasehold improvements. Nothing further.


The deduction is limited to $500,000 of equipment purchases in a single year. Equipment that qualifies for the deduction but exceeds $500,000 can be depreciated across future tax years. The deduction isn’t lost; it’s simply delayed.
