The quote is on your desk: a new CT scanner, a delivery truck, a set of dental chairs, or a server upgrade. The vendor offers three ways to pay—cash, a bank loan, or a lease with a low monthly payment. Most owners pick whichever option feels easiest on cash this month. That shortcut can cost tens of thousands of dollars over the life of the equipment.
In 2026 the lease vs. buy decision deserves a real calculation. The One Big Beautiful Bill Act made 100% bonus depreciation permanent for qualifying property acquired after January 19, 2025, and raised the Section 179 expensing limit to $2.5 million (indexed for inflation). Meanwhile, equipment financing rates remain well above where they were a few years ago. Here is how to compare your options before you sign anything—and before the December 31 placed-in-service deadline.
Key Takeaways
- Compare options on after-tax present value, not monthly payment. The lowest payment is often the most expensive choice.
- Buying (with cash or a loan) can unlock a full first-year deduction through bonus depreciation or Section 179.
- A “$1 buyout” lease is usually treated as a purchase for tax purposes, so it can qualify for the same deductions.
- Equipment must be placed in service by December 31, 2026 to be deducted on this year’s return.
The Three Ways to Acquire Equipment
Before running numbers, be clear about what you are actually being offered. The structure of the deal determines the tax treatment, the accounting, and your flexibility down the road.
| Option | Who Owns It | Tax Treatment | Best For |
|---|---|---|---|
| Cash purchase | You, immediately | Depreciation, bonus, or Section 179 | Strong cash reserves, long useful life |
| Loan or $1 buyout lease | You (lender holds a lien) | Depreciation plus deductible interest | Preserving cash while capturing deductions |
| True (fair market value) lease | The lessor | Lease payments deducted as rent | Technology that becomes obsolete quickly |
Why the 2026 Tax Rules Favor Ownership
When you buy equipment, you generally recover its cost through depreciation. With 100% bonus depreciation back for good, you can often write off the entire purchase price in the first year—even if you financed most of it. A $200,000 machine bought with a loan in November can produce a $200,000 deduction on your 2026 return while you pay for it over five years.
With a true lease, you deduct only the payments you actually make during the year. That same equipment leased in November might produce just two months of rent deductions in 2026.
Section 179 vs. Bonus Depreciation
Both can deliver a full first-year write-off, but they work differently. Section 179 is elective asset by asset and cannot create a business loss, while bonus depreciation can generate a loss that carries forward. Many states do not conform to federal bonus depreciation, which can change the math. Our detailed comparison of Section 179 and bonus depreciation walks through which to use when.
Do Not Let the Tax Tail Wag the Dog
A big deduction is valuable only if you need it. If your income is low this year, or you expect to be in a higher bracket later, front-loading depreciation may not be ideal. And when you eventually sell equipment you fully expensed, the gain is taxed as ordinary income under the depreciation recapture rules.
How to Run a Real Lease vs. Buy Analysis
Comparing monthly payments ignores taxes, timing, and residual value. A proper analysis follows five steps:
- List every cash flow. Down payment, monthly payments, fees, maintenance, insurance, and any buyout or return costs.
- Apply the tax effect. Multiply deductions (depreciation, interest, or rent) by your combined marginal tax rate in the year they occur.
- Estimate residual value. What will the equipment be worth when the lease ends or when you would sell it?
- Discount to present value. Use your after-tax cost of borrowing so a dollar saved today counts more than a dollar saved in year five.
- Compare the totals. The option with the lowest after-tax present value cost wins on economics.
Our financial planning and analysis team builds these models for clients and stress-tests them against different tax rates and interest rate scenarios.
The question is not “which payment is lower?” It is “which option leaves more money in the business after taxes, over the full life of the asset?”
When Leasing Still Makes Sense
Ownership is not always the winner. A true lease can be the smarter choice when:
- Technology changes fast. Imaging systems, lasers, and IT hardware can be outdated in three years. Leasing shifts obsolescence risk to the lessor.
- Cash and credit are tight. Leases often require little or no down payment and may not count against bank loan covenants the same way.
- You do not need the deduction. If your taxable income is already low, accelerated depreciation adds little value.
- Service is bundled. Some leases include maintenance and upgrades that would cost extra on a purchased unit.
Watch the Balance Sheet Under ASC 842
Leasing no longer keeps obligations off your books. Under the ASC 842 lease accounting standard, most leases longer than 12 months must be recorded as a right-of-use asset and a lease liability. Lenders and buyers will see them. Our financial reporting specialists make sure leases are recorded correctly so your statements hold up to lender review.
Special Considerations for Medical Practices
Practices face some of the largest equipment decisions of any small business. Before signing:
- Model reimbursement. Tie projected payments to realistic procedure volume and payer rates, not the vendor’s best-case estimate.
- Read the end-of-term clause. Automatic renewals and costly return conditions are common in medical equipment leases.
- Plan for partner changes. If ownership may change, decide who carries the obligation and how it affects practice valuation.
Our medical practice finance team reviews equipment proposals alongside your revenue cycle data so purchases are justified by real collections.
Year-End Checklist Before You Sign
- Confirm whether the agreement is a true lease or a financed purchase for tax purposes.
- Make sure the equipment will be delivered, installed, and ready for use by December 31. Ordering or paying is not enough.
- Check your state’s conformity to bonus depreciation.
- Review loan covenants and how the new obligation affects your ratios.
- Coordinate the purchase with your year-end tax plan so the deduction lands where it is most valuable.
The Bottom Line
The right answer depends on your tax bracket, cash position, borrowing cost, and how long the equipment will stay useful. In 2026, permanent bonus depreciation tilts many decisions toward ownership, but leasing still wins for fast-changing technology and cash-constrained businesses. The only way to know is to run the numbers on an after-tax basis.
