Upgrading your dental imaging equipment can improve your practice’s workflow and diagnostic capabilities. It may also offer a valuable tax benefit.
Section 179 allows eligible businesses to deduct the cost of qualifying equipment in the year it is placed into service, rather than spreading the deduction over several years. For dental practices considering a CBCT system, panoramic X-ray, or digital sensors, that could meaningfully reduce the cost of an investment you already need.
Both new and qualifying recertified equipment may be eligible, and financing may allow you to preserve working capital while taking advantage of an available deduction.
Here’s what to know before planning your 2026 purchase.
What Dental Imaging Equipment May Qualify?
Qualifying equipment may include:
- Cone Beam Computed Tomography (CBCT) scanners
- Panoramic X-ray systems
- Cephalometric imaging equipment
- Digital intraoral X-ray systems
- Digital radiography sensors
- Other qualifying dental diagnostic and imaging equipment
Eligibility depends on the equipment, purchase transaction, business use, and your practice’s tax circumstances.
Does Recertified Dental Imaging Equipment Qualify?
Section 179 isn’t limited to brand-new equipment. Qualifying used and recertified dental imaging systems may also be eligible, provided the purchase and business use meet IRS requirements.
For practices considering a recertified CBCT, panoramic system, or digital sensor, this can combine a lower purchase price with a potential first-year tax deduction.
The equipment does not have to be newly manufactured to qualify. However, restrictions apply to certain transactions, including purchases from related parties. Your CPA can confirm eligibility for your specific purchase.
Section 179 in 2026: What Dental Practices Need to Know
For tax years beginning in 2026, the federal Section 179 limits are:
|
Section 179 provision |
2026 limit |
|
Maximum deduction |
$2,560,000 |
|
Equipment spending phaseout threshold |
$4,090,000 |
The maximum deduction decreases dollar for dollar when the cost of qualifying Section 179 property placed into service during the tax year exceeds $4,090,000. For most independent dental practices, these thresholds are well above the cost of a typical imaging equipment purchase.
Section 179 is also subject to a taxable business income limitation. If that limitation prevents you from using the full deduction, the unused amount can generally be carried forward to future tax years.
Generally, equipment must:
- Qualify as eligible business property.
- Be acquired through a qualifying purchase.
- Be used more than 50% for business purposes.
- Be placed into service during the applicable tax year.
For equipment with both business and personal use, only the eligible business portion of its cost can be considered.
The Year-End Deadline: Ordering Alone Isn’t Enough
For practices using a calendar tax year, equipment generally must be placed into service by December 31, 2026, to qualify for a 2026 deduction.
Simply ordering equipment, paying a deposit, or receiving an invoice before year-end does not establish that it has been placed into service. Generally, it must be ready and available for its intended business use.
For dental imaging equipment, that means planning for delivery, installation, calibration, software integration, and any applicable site or regulatory requirements.
Starting early gives your practice more time to coordinate those steps and address unexpected delays.
How Much Could Your Dental Practice Save?
Imagine your practice purchases a recertified CBCT system for $40,000. If the entire cost qualifies and your practice meets the applicable requirements, you may be able to deduct the full $40,000 in the year the equipment is placed into service.
The following examples illustrate how the tax benefit could vary:
|
Illustrative marginal tax rate |
Potential tax savings on a $40,000 deduction |
|
24% |
$9,600 |
|
32% |
$12,800 |
|
35% |
$14,000 |
At an illustrative 32% marginal tax rate, a fully eligible $40,000 deduction could reduce taxes by approximately $12,800. That brings the equipment’s cost after the illustrated tax benefit to $27,200, before financing costs.
A deduction reduces taxable income. It does not reimburse the purchase price or provide a dollar-for-dollar tax credit.
Actual savings depend on your business structure, applicable tax rates, available income, other deductions, and federal and state tax treatment. These examples assume the full deduction can be used at the stated rate.
Section 179 also accelerates deductions that would otherwise generally be taken over time. Your CPA can help evaluate whether taking a larger deduction now fits your practice’s overall tax strategy.
Can You Finance Equipment and Still Benefit from Section 179?
Yes. A qualifying financed purchase may still be eligible for Section 179.
Equipment does not necessarily have to be paid for entirely in cash before you can claim an eligible deduction. Depending on the financing structure and ownership arrangements, your practice may be able to deduct the qualifying equipment cost in the year it is placed into service while making loan payments over several years.
For example, a practice purchasing a $40,000 CBCT through a qualifying equipment loan may be eligible for a deduction based on the qualifying purchase price, rather than just the principal payments made that year.
This can help your practice:
- Preserve working capital: Keep cash available for payroll, supplies, and everyday operating expenses.
- Upgrade sooner: Spread the purchase payments over time.
- Accelerate eligible deductions: Potentially claim the qualifying deduction in the year the equipment is placed into service.
Financing still creates a repayment obligation, and interest and fees affect the total cost. Lease and rental arrangements can receive different tax treatment, so have your CPA review the agreement before proceeding.
Don’t Overlook 100% Bonus Depreciation in 2026
Section 179 is not the only option for accelerating equipment deductions.
Federal legislation enacted in July 2025 restored 100% bonus depreciation for qualifying property acquired and placed into service after January 19, 2025, with no scheduled phaseout under current law.
Section 179 and bonus depreciation have different rules. Section 179 has an annual deduction cap, a spending phaseout, and a taxable business income limitation. Bonus depreciation generally does not have those same limitations, although other tax rules may restrict how a resulting loss can be used.
Qualifying new and certain used dental imaging equipment may be eligible for bonus depreciation.
Your CPA can determine whether Section 179, bonus depreciation, or deductions spread over future years best fit your practice. The same equipment cost cannot be deducted twice.
Planning a Dental Imaging Upgrade Before Year-End?
Global Imaging can help you compare recertified CBCT systems, panoramic X-ray equipment, and digital sensors, explore financing options, and review delivery and installation availability.
Choosing recertified equipment can lower your upfront investment. An eligible tax deduction may reduce the cost further, while financing can help preserve cash for your practice.
Contact Global Imaging for a quote and discuss the potential tax benefits with your CPA before purchasing. Planning early gives your practice more time to coordinate equipment selection, financing, site preparation, and installation before year-end.
