Dental equipment purchases often qualify for significant tax deductions through Section 179 and bonus depreciation. These provisions let you deduct part or all of the cost in the year of purchase rather than spreading it across multiple years through standard depreciation.

Section 179 is the most commonly used option for dental practices. It allows you to deduct the full purchase price of qualifying equipment in the year you put it into service. For 2024, you can deduct up to $1,160,000 in equipment purchases. Most dental practices won’t hit that ceiling. The deduction phases out if your total equipment purchases exceed $2,890,000, which doesn’t apply to typical solo or small group practices.

Qualifying dental equipment includes operatory chairs, x-ray machines, panoramic imaging systems, CBCT scanners, CAD/CAM systems, sterilization equipment, intraoral cameras, dental lasers, computers, and practice management software. Office furniture and waiting room equipment also qualify. The equipment needs to be used primarily for business purposes with at least 50% business use.

Bonus depreciation works alongside or instead of Section 179. It’s currently at 60% for 2024 and decreases each year. This applies to new and used equipment as long as it’s new to your practice. Unlike Section 179, there’s no income limitation with bonus depreciation, which can matter for practices with large purchases in lower-income years.

If you don’t use these accelerated methods, standard depreciation spreads the deduction over 5 to 7 years depending on the asset type. This rarely makes sense unless you’re trying to preserve deductions for future higher-income years.

Timing matters for tax planning. Equipment placed in service before year-end qualifies for that tax year. Many dental offices make large equipment purchases in the fourth quarter after reviewing projected income with their accountant. The key phrase is “placed in service,” meaning installed and ready for use, not just ordered or delivered.

Financed equipment still qualifies for these deductions. You can deduct the full purchase price in the year of purchase even if you’re paying it off over several years. This creates valuable tax savings upfront while you spread the actual cash outlay over time.

Keep detailed records of all equipment purchases including invoices, proof of payment, and documentation of when each piece was placed in service. A Los Angeles County bookkeeper for small business can help ensure your records support the deductions you’re claiming and that equipment purchases are properly tracked in your accounting system.

These tax provisions change periodically, and what’s optimal depends on your practice’s income level and overall tax situation. Coordinate with your tax professional to determine the best approach for your specific circumstances.
