When you need to buy used lease or finance equipment, I look at three numbers first: your current-year taxable income, your cash reserves, and how long you plan to keep the machine. The dealer's incentive is to move inventory, not to optimize your tax outcome. My job is to keep the most after-tax money in your business.

What is the real difference between buying used, leasing, and financing equipment?

Buying used means you own the asset. You record it on your books, take depreciation deductions, and if you sell it later you may owe depreciation recapture. You also pay cash or drain a line of credit upfront.

Leasing is renting with a contract. You do not own the equipment at the end unless you exercise a purchase option. Lease payments are generally deductible as a business expense, which simplifies bookkeeping.

Financing new equipment is buying with a loan. You own it from day one, so you get depreciation deductions and the Section 179 write-off if you qualify. You also deduct the interest portion of your payments. The downside is the debt service.

How much can you deduct in 2026?

The deduction landscape for 2026 is unusually generous. Bonus depreciation is back to 100% for qualifying property placed in service after January 19, 2025, under the OBBBA restoration. That means you can write off the full cost in year one on eligible new or used equipment.

Section 179 is also active. The 2026 limit is $2,560,000, and the phase-out starts when total equipment purchases exceed $4,090,000. If you buy a $60,000 excavator, you can elect Section 179 to expense it immediately, take 100% bonus depreciation, or use regular MACRS over five or seven years. Most contractors with taxable income will take the immediate write-off. (IRC §179(b)(1); §168(k))

When should you buy used equipment?

Buy used when you can pay cash or pay off the note quickly, and when the machine has enough useful life left to justify the maintenance risk. You still get the same Section 179 and bonus depreciation benefits as new equipment, provided the asset is new to you and used more than 50% for business. (IRC §179; §168(k))

The trap is maintenance. A used skid steer at $25,000 looks cheap until you replace the hydrostatic pump in month three. I tell clients to budget 10% to 20% of the purchase price for immediate repairs and to verify the serial number is not tied to any outstanding liens.

When should you lease instead?

Lease when cash is extremely tight and the equipment becomes obsolete quickly. If you need a specialized attachment for a six-month job and will not touch it again, a lease preserves your line of credit. The monthly payment is fixed, predictable, and fully deductible as an ordinary business expense.

The trade-off is no equity. At the end of the lease you return the equipment or buy it at fair market value. You also cannot take bonus depreciation or Section 179 on a true lease because you do not own the asset. If your effective tax rate is low this year, giving up the big upfront deduction might not hurt much.

When should you finance new equipment?

Finance new equipment when you have stable, predictable revenue and the machine will run five to seven years. New equipment comes with warranties, lower maintenance, and better financing rates if your business credit is solid. Because you own it, you get the full depreciation stack: Section 179, 100% bonus depreciation under IRC §168(k), or MACRS, plus interest deduction. See Contractor Equipment Depreciation: 2026 Rules for the full breakdown of methods.

In 2026, with bonus depreciation at 100%, a financed $80,000 work truck can generate a first-year deduction that exceeds your down payment plus principal payments. That creates a timing difference that helps cash flow. The vehicle write-off rules have their own limits if the truck is over 6,000 pounds, so verify the GVWR before you sign. Just remember: depreciation recapture waits if you sell it later for more than its written-down basis.

How do the three options compare side by side?

What records do you need to keep?

Keep the purchase invoice, financing agreement, and a business-use log for every major asset. If you lease, keep the lease agreement and proof of payment. The rules for tax write-offs for tools and equipment apply the same whether you pay cash or finance.

The equipment must be used more than 50% for business to qualify for Section 179 or bonus depreciation. If business use drops below 50% in later years, you trigger depreciation recapture under IRC §1245, which means adding prior deductions back into income. Track hours or miles from day one.

What is the short version?

If you have the cash and the equipment has a long life, buy used and take the 100% bonus depreciation while it lasts. If you need to preserve every dollar of cash for payroll and materials, lease and deduct the payments. If your revenue is steady and you want warranties plus the biggest deduction stack, finance new and pair Section 179 with the interest write-off. Match the payment structure to your job costing reality. If the machine does not generate enough gross profit to cover the note or lease, the deduction is cold comfort.
