Equipment Leasing & Section 179 Strategy

Write Off $500K-$1M in Equipment With Just 10% Down

Equipment leasing lets business owners acquire the tools they need and deduct the full cost immediately -- even when financing.

10% down payment 3% closing costs 100% bonus depreciation is permanent New and used equipment qualify

Section 1

The Numbers: Spend $65K, Save $175K

This is the part most business owners have never had modeled for them. When you finance equipment, the deduction is based on the full purchase price—not the cash you put down. That gap is where the strategy lives.

10% down

A standard structure across our lending partners for qualified borrowers. On a $500,000 machine, that is $50,000.

3% closing costs

Documentation, filing, and funding costs run roughly 3% of the equipment price and are due at signing.

Platform / origination fee

Varies by lender, credit tier, and term. We surface the all-in number before you sign anything, not after.

Example A

$500,000 Equipment Purchase

Down payment (10%)$50,000
Closing costs (3%)$15,000
Total out of pocket$65,000
Section 179 deduction$500,000
Tax savings at 35%$175,000+
Net Year 1 position +$110,000

You spend $65,000 and save $175,000. The equipment is yours, working, and generating revenue.

Example B

$1,000,000 Equipment Purchase

Down payment (10%)$100,000
Closing costs (3%)$30,000
Total out of pocket$130,000
Bonus depreciation deduction$1,000,000
Tax savings at 35%$350,000+
Net Year 1 position +$220,000

Above the Section 179 cap, bonus depreciation carries the deduction with no dollar limit.

Savings shown use a blended 35% federal and state marginal rate. Your actual rate depends on entity type, state, and taxable income. We model your specific numbers before you commit to a purchase—read the deeper breakdown in how to finance equipment with 10% down and still get the full deduction.

Section 2

How It Works

Five steps from first conversation to a filed return with the deduction locked in.

1

Identify qualifying equipment

Vehicles, machinery, medical, technology, and construction assets all qualify as tangible personal property under IRC Sec. 179(d)(1). We confirm eligibility before you shop, including the mixed-use and over-6,000-lb vehicle rules that trip up most buyers.

2

Work with our lending partners to structure the lease

The structure determines the tax result. We make sure the paperwork is drafted as a capital lease with a bargain buyout so you are the tax owner and can claim depreciation, rather than a true operating lease that only produces a rent deduction.

3

10% down, 3% closing—equipment delivered

You fund the down payment and closing costs, the lender funds the balance, and the vendor delivers. We track the in-service date because that is the trigger for the entire deduction.

4

We file Section 179 or bonus depreciation on your return

Form 4562, the Section 179 election, the asset schedule, and the supporting documentation file. We model both methods and choose the split that produces the best result across federal, state, and QBI.

5

Full purchase price deducted in Year 1

The deduction is based on the equipment cost, not your cash outlay. The savings hit the same tax year, often before you have made twelve monthly payments.

Section 3

What Equipment Qualifies

If it is tangible personal property used more than 50% in your trade or business, it is almost certainly eligible. New and used both qualify.

Construction

Excavators, loaders, cranes, concrete equipment, skid steers, and attachments.

Medical

Imaging machines, dental chairs, surgical equipment, ambulances, and sterilization systems.

Restaurant

Commercial kitchens, walk-in coolers, POS systems, hoods, and prep lines.

Trucking

Semi trucks, trailers, refrigerated units, and telematics and fleet hardware.

Manufacturing

CNC machines, injection molding, assembly lines, press brakes, and robotics cells.

Technology

Servers, networking, storage arrays, and specialized off-the-shelf software.

Agriculture

Tractors, combines, irrigation systems, grain handling, and implements.

Auto dealership

Lifts, diagnostic equipment, body shop tools, alignment racks, and paint booths.

Landscaping

Mowers, trucks, trailers, skid steers, and hardscape equipment.

Industry-specific deep dives: heavy equipment for construction companies, medical equipment deductions for healthcare practices, fleet depreciation for trucking companies, and commercial kitchen write-offs for restaurants.

Section 4

Section 179 vs Bonus Depreciation

Two provisions, both producing an immediate write-off, with very different limits. Most large acquisitions use a deliberate combination of the two.

  Section 179 Bonus Depreciation
Annual limit $1,220,000 (2025). The 2026 inflation-adjusted limit is $1,250,000. No cap. Unlimited dollar amount.
Phase-out Phases out dollar-for-dollar above $3,050,000 of equipment placed in service ($3,130,000 in 2026). No phase-out threshold.
Current rate 100% expensing up to the cap. 100%, permanent under the One Big Beautiful Bill Act (OBBBA).
Timing requirement Must be placed in service during the tax year. Must be placed in service during the tax year.
New or used Applies to new and used equipment. Applies to new and used equipment.
Can it create a loss? No. Limited to your business taxable income; the excess carries forward. Yes. Can create or increase a net operating loss.
Asset-by-asset election Yes. Apply it selectively to individual assets and fine-tune taxable income. Applied by asset class; elect out only by class, not by individual asset.

Which is better?

Usually bonus depreciation for large purchases, Section 179 for targeted deductions. Bonus depreciation wins when the acquisition exceeds the Section 179 cap, when you want to create a loss, or when your business income is too low to absorb a 179 election. Section 179 wins when you want surgical control over how much income you shelter, when the asset is not bonus eligible, or when your state decouples from federal bonus rules.

We model both for every client. The ordering rule is fixed—179 first, then bonus, then MACRS—so the split has to be decided before the return is filed, not after. See the full comparison in our 2026 Section 179 guide and equipment leasing vs buying.

Section 5

Entity Structure Matters

The same machine produces a different after-tax result depending on which entity buys it. Equipment purchased by the right entity maximizes the deduction—and the wrong one can strand it.

S-Corp

The deduction flows to your K-1 and reduces the income you report personally, which reduces the reasonable-compensation and SE-adjacent income you are taxed on. Watch the stock and debt basis limitation under IRC Sec. 1366(d): corporate-level equipment debt does not create shareholder basis the way partnership debt does.

C-Corp

The deduction lands against income taxed at the flat 21% corporate rate. That is a lower rate of benefit per dollar, but it can be the right home when the equipment sits in a leasing entity, when you are accumulating earnings inside the corporation, or when the pass-through would waste the deduction.

LLC

Depends on the tax election. A partnership-taxed LLC allocates the deduction by operating agreement and includes entity debt in partner basis, which is often the cleanest way to make a financed purchase deductible in Year 1. A disregarded single-member LLC reports on Schedule C or E.

We structure the purchase before you buy

Basis, at-risk rules under IRC Sec. 465, passive activity limits under IRC Sec. 469, the QBI interaction under IRC Sec. 199A, and state conformity all change the answer. Restructuring after the equipment is titled and financed is expensive and sometimes impossible, which is why the entity decision belongs in front of the purchase, not behind it.

Section 6

Real Examples

De-identified client outcomes. Tax savings reflect a blended 35% federal and state marginal rate applied to the full first-year deduction.

Construction company: $750K excavator package

Equipment cost
$750,000
Down payment (10%)
$75,000
First-year deduction
$750,000
Tax savings
$262,000

An S-Corp contractor replaced two aging machines in Q4. The deduction offset a strong year of margin, and the savings exceeded the down payment by more than 3x.

Medical practice: $400K imaging machine

Equipment cost
$400,000
Down payment (10%)
$40,000
First-year deduction
$400,000
Tax savings
$140,000

A specialty practice brought imaging in-house instead of referring it out. New revenue line, new deduction, and the machine was commissioned on December 12—inside the in-service window.

Trucking company: $1.2M fleet purchase

Equipment cost
$1,200,000
Down payment (10%)
$120,000
First-year deduction
$1,200,000
Tax savings
$420,000

Above the Section 179 cap, so bonus depreciation carried the full amount. Eight tractors and six trailers, all placed in service before year-end and documented by route logs.

Restaurant group: $300K kitchen buildout

Equipment cost
$300,000
Down payment (10%)
$30,000
First-year deduction
$300,000
Tax savings
$105,000

Line equipment, walk-in refrigeration, and POS across two locations. We separated the qualifying personal property from the leasehold improvements so each got the right recovery treatment.

Examples are de-identified and simplified for illustration. Individual results depend on entity type, state, taxable income, basis, and the at-risk and passive activity rules.

Section 7

Frequently Asked Questions

What is the minimum credit score for equipment financing?

Most equipment lenders look for a personal credit score of 650 or better, and the strongest pricing generally starts around 700. Below 650 is still fundable, but expect a larger down payment, a shorter term, or a personal guarantee with additional collateral. Lenders weigh time in business, revenue, and the resale value of the equipment alongside the score, so a contractor with four years of history and a hard asset behind the loan often clears underwriting at a score that would be declined on an unsecured line. The tax treatment does not change based on your credit score: a $500,000 machine produces a $500,000 deduction whether you financed at 7% or 12%.

Can I deduct leased equipment on my taxes?

Yes, but the deduction takes one of two forms depending on how the lease is structured. A capital lease, also called a finance lease or a $1 buyout lease, is treated as a purchase for tax purposes. You are the tax owner, you claim depreciation on the full equipment cost under Section 179 or bonus depreciation, and you deduct the interest portion of your payments. A true operating lease, where the lessor retains ownership and residual risk, is not a purchase—you deduct the lease payments as ordinary business rent under IRC Sec. 162 as you make them. Both are legitimate deductions, but only the capital lease produces a large Year 1 write-off. Full breakdown here.

What is the difference between a capital lease and an operating lease?

A capital lease transfers the benefits and burdens of ownership to you. Typical markers are a bargain purchase option such as a $1 or 10% buyout, a lease term covering most of the asset's useful life, and total payments that approximate the purchase price. For tax purposes you are the owner, so you depreciate the equipment and deduct interest. An operating lease is a rental: the lessor keeps meaningful residual risk, the term is shorter than the useful life, and the buyout is at fair market value. You deduct the payments as rent instead of claiming depreciation. Structure matters—the same machine at the same monthly payment can generate a $500,000 Year 1 deduction or a $95,000 annual rent deduction depending on how the paperwork is drafted.

Do I need to put the equipment in service before year-end?

Yes. Both Section 179 and bonus depreciation require the asset to be placed in service during the tax year, which means ready and available for its intended use in your business. Ordering the equipment, signing the lease, wiring the down payment, and even taking delivery are not sufficient on their own if the machine is still crated, uninstalled, or awaiting a required inspection or license on December 31. Practically, this means starting the acquisition in October or early November rather than the last week of December, and documenting the in-service date with delivery receipts, installation sign-offs, commissioning reports, and the first job or route the asset ran. More on timing here.

Can I use Section 179 and bonus depreciation together?

Yes, and on most large acquisitions you should. The ordering rule is fixed: Section 179 is elected first on the specific assets you designate, bonus depreciation under IRC Sec. 168(k) then applies to the remaining basis of eligible property, and regular MACRS depreciation covers anything left. A common pattern is to use Section 179 selectively on assets that are not bonus eligible or on a state return that decouples from federal bonus rules, then let 100% bonus depreciation absorb the rest. Because Section 179 is capped by business taxable income and bonus depreciation is not, the split changes the answer on whether you can create a loss.

What happens if I sell the equipment before the lease is paid off?

Two things happen at once. On the financing side, the outstanding balance becomes due and is typically paid from the sale proceeds at closing. On the tax side, you face depreciation recapture: because you already deducted the full cost, your adjusted basis is at or near zero, so most of the sale price is recaptured as ordinary income under IRC Sec. 1245 rather than as capital gain. Selling a fully expensed $500,000 excavator for $300,000 generally creates $300,000 of ordinary income in the year of sale. This is a timing consequence rather than a penalty, and it can be managed with an installment structure or by pairing the sale year with a replacement purchase that generates offsetting deductions.

Is there a limit on how much equipment I can write off?

Section 179 is capped. The 2025 limit is $1,220,000 with a dollar-for-dollar phase-out once total equipment placed in service exceeds $3,050,000, and the deduction cannot exceed your aggregate business taxable income. The 2026 inflation-adjusted figures are $1,250,000 and $3,130,000. Bonus depreciation has no dollar cap and no phase-out threshold, and under the One Big Beautiful Bill Act it is 100% on a permanent basis. That is why a fleet buyer spending $4 million uses bonus depreciation rather than Section 179—the cap and the income limitation simply do not apply.

Can I lease equipment through my S-Corp?

Yes, and for most operating businesses the S-Corp is the right owner. The depreciation deduction reduces the corporation's ordinary business income, flows to you on the K-1, and reduces the income subject to tax at your individual rate. Two limitations shape the result. Section 179 passes through subject to a shareholder-level business income limitation, and any loss you claim is capped by your stock and debt basis under IRC Sec. 1366(d). A financed purchase inside an S-Corp does not automatically create basis, because corporate-level debt is not allocated to shareholders the way partnership debt is. If the deduction would exceed your basis, the fix is planned in advance through a capital contribution, a direct shareholder loan, or holding the equipment in a separate entity that leases it back.
