An equipment purchase can make a noticeable difference to your tax bill. But before approving a new machine, replacing your office computers, or upgrading the kitchen in your restaurant, it helps to understand what the deduction will actually do for your business.
The comparison of bonus depreciation vs. Section 179 in 2026 is more nuanced than choosing whichever offers the largest write-off. For many qualifying purchases, either provision could allow the same first-year federal deduction. The differences become more important when your business has limited taxable income, you want to control how much you deduct, or your state treats the two options differently.
A useful tax-planning conversation starts with the purchase itself: whether you need it, when it will be ready for use, and how paying for it will affect the cash you need to operate.
Bonus Depreciation in 2026: The Rules Have Changed
Older articles may still describe a bonus depreciation phase-down to 20% in 2026. That is no longer the general rule for new qualifying purchases.
Federal law restored 100% bonus depreciation for qualifying property acquired and placed in service after January 19, 2025. That treatment has no scheduled phase-down under current law.
The acquisition date still matters. Equipment subject to an older binding purchase contract may fall under different rules, even if it is delivered in 2026. If you have a long-running order or construction arrangement, have your advisor review the agreement rather than relying only on the invoice date.
For an owner considering an ordinary equipment purchase this fall, the practical point is that a full federal deduction may be available. Whether claiming it immediately is the best choice requires a closer look at the rest of the return.
Section 179 Limits for 2026
For tax years beginning in 2026, the federal Section 179 limits are:
| Section 179 provision | 2026 amount |
| Maximum deduction before other limitations | $2,560,000 |
| Qualifying property cost at which the deduction begins to phase out | $4,090,000 |
| Qualifying property cost at which the deduction is fully phased out | $6,650,000 |
The maximum deduction falls dollar for dollar once the total cost of Section 179 property placed in service exceeds $4,090,000. The $6,650,000 full phase-out follows from adding that threshold to the $2,560,000 maximum deduction. These are aggregate limits, not a separate allowance for each purchase.
Most small business owners will be well below those spending levels. For them, the more relevant restriction is often the business income limitation.
The Section 179 deduction is generally limited to taxable income from actively conducted trades or businesses, calculated under special rules. Amounts disallowed because of that income limit can generally carry forward.
That calculation is not necessarily the profit shown on one company’s financial statements. Depending on the taxpayer, other active business income and wages can matter. Partnerships and S corporations also require review at both the entity and owner levels.
Section 179 vs. Bonus Depreciation: What Actually Differs?
Both provisions accelerate the recovery of qualifying asset costs. Their limitations and election rules, however, can lead to different outcomes.
| Consideration | Section 179 | Bonus depreciation |
| First-year deduction | Elected amount, subject to applicable limits | Generally 100% of eligible remaining basis for qualifying acquisitions |
| Overall dollar cap | Annual cap and spending phase-out | No comparable overall dollar cap or spending phase-out |
| Business income restriction | Subject to an active business income limit | Can create or increase a tax loss, subject to other loss rules |
| Flexibility | Select qualifying assets and amounts to expense | Generally applies automatically; electing out usually applies to an entire property class |
| New or used equipment | Both may qualify | Both may qualify, subject to acquisition requirements |
Section 179 provides more control over which qualifying purchases you expense and how much you claim. Bonus depreciation generally applies unless you elect out, and that election usually covers all eligible property in the same class placed in service during the year. It is not ordinarily an item-by-item choice.
That distinction matters if you want to deduct one purchase immediately while spreading another purchase’s cost over future years. Your advisor needs the complete asset list to make that decision properly.
Which Equipment Qualifies?
Common candidates include machinery, computers, office furniture, restaurant equipment, and medical or dental equipment. Certain purchased software can also qualify. For the usual equipment bonus depreciation rules, eligible property generally includes assets with a tax recovery period of 20 years or less.
Used equipment is not automatically excluded. However, purchases from related parties and assets you previously used can raise eligibility issues.
Section 179 generally requires more than 50% business use in the year the property is placed in service. Only the business portion of the cost is eligible. Vehicles and other listed property have additional business-use restrictions.
Building work deserves separate attention. Certain improvements to nonresidential buildings, including qualifying roofs, HVAC systems, security systems, and fire protection systems, can be eligible for Section 179. Bonus depreciation has its own eligibility rules, so the same improvement may not receive identical treatment under both provisions. Land itself is not depreciable.
For a restaurant renovation or a medical office expansion, ask for invoices that separate equipment from construction work. A single invoice labeled “renovation” gives your advisor much less useful information than an itemized breakdown.
Vehicles Need Their Own Calculation
A vehicle purchase should not be evaluated using a general equipment example.
For 2026, certain heavy SUVs are subject to a $32,000 Section 179 cap. That limits the Section 179 portion; it does not necessarily limit the total available deduction, because qualifying remaining basis may receive bonus depreciation. Passenger automobile limits, vehicle design, and documented business use can change the result.
Before accepting a dealer’s “write it all off” explanation, have your advisor review the specific vehicle and how you will use it.
A Larger Deduction Does Not Always Mean Greater Savings
Suppose your business purchases $80,000 of qualifying equipment and uses it entirely for business. Assume it meets the requirements for both provisions, has enough eligible income for Section 179, and faces no other applicable limitations.
Either Section 179 or 100% bonus depreciation could potentially produce an $80,000 first-year federal deduction. Under those assumptions, choosing bonus depreciation does not automatically generate more federal savings.
The tax benefit also differs from the purchase price.
In a simplified illustration, an $80,000 deduction that offsets income otherwise taxed at 24% would reduce federal income tax by $19,200. That is not an $80,000 refund. Before considering financing, state taxes, or other tax interactions, the purchase still represents a $60,800 cost after that assumed federal tax benefit.
Actual savings depend on your tax situation, including whether the deduction crosses tax brackets or affects other deductions.
This is why buying equipment solely to reduce taxes can leave an owner disappointed. The purchase should improve the business enough to justify the money that remains spent after the deduction.
A Loss Can Change When the Benefit Reaches You
Bonus depreciation can create a tax loss, but a loss on the business return does not necessarily translate into an immediate reduction of the owner’s other taxable income.
Depending on the business structure and circumstances, basis, at-risk, passive activity, excess business loss, and net operating loss rules may restrict or defer the benefit.
If your business is already operating at a loss, ask your advisor to show when the additional deduction is expected to become usable. That timing belongs in the purchase decision.
Buying Before December 31 Is Not Enough
For a calendar-year business seeking a 2026 deduction, the equipment generally must be placed in service by December 31, 2026. That means it is ready and available for its intended business use.
An order confirmation, deposit, or paid invoice does not establish that requirement on its own.
If equipment arrives in December but cannot operate until installation is completed in January, a December payment will not necessarily support a 2026 deduction. On the other hand, equipment that is fully ready and available before year-end does not necessarily have to wait for its first customer job to be considered in service.
As you plan purchases this fall, check installation schedules alongside delivery dates. Confirm whether electrical work, software configuration, or other setup must be completed before the equipment can perform its intended function.
Keep the purchase agreement and installation records with the invoice. Those details are far easier to document when the work happens than to reconstruct during tax preparation.
Financing Can Preserve Cash, but the Payments Continue
You do not necessarily have to pay the full purchase price in cash to claim a tax deduction for business equipment. For an owned asset purchased with financing, its tax basis generally includes the financed cost, subject to the applicable rules. A qualifying deduction may therefore exceed the down payment.
That can be helpful when equipment is necessary and you want to preserve working capital. It also creates a timing issue: you may claim the deduction now while making loan payments for several more years.
Once the equipment’s cost has been fully deducted, there is no remaining depreciation deduction for that same cost in later years. Loan principal payments do not create a second equipment deduction.
Before financing a purchase, review the payment schedule against expected cash flow. Leave room for payroll, slower customer collections, and the other expenses that will continue after the tax return is filed.
State Taxes Can Change the Better Choice
Federal savings are only part of the comparison.
For Minnesota businesses and owners, ordinary federal bonus depreciation generally requires an 80% state addback, with recovery through deductions over the following five years. That can spread the Minnesota benefit over time even when the federal deduction is taken immediately.
This is a reason to compare Section 179 and bonus depreciation at both levels before making an election. An approach that produces the same federal deduction can produce a different state result.
Businesses operating across state lines need a broader review. The state where you buy the equipment is not necessarily the only state relevant to your tax return.
What to Review Before Committing to a Purchase
Bring your advisor the equipment quote while there is still time to change the plan. Include the expected delivery and installation dates, financing terms, and any personal use.
The discussion should address:
- Whether the purchase qualifies and which costs belong in the asset’s tax basis.
- How much of the deduction can be used on the 2026 business and owner returns.
- Whether Section 179, bonus depreciation, or regular depreciation produces the better result over several years.
- How state treatment affects the projected savings.
- Whether the business can comfortably afford the purchase after taxes and financing costs.
Ask for a comparison showing the tax position with and without the purchase. A useful projection should make the remaining cash cost clear.
Also mention any plans to sell or trade existing equipment. A sale can produce taxable gain, including depreciation recapture, even when the asset has already been fully written off.
Frequently Asked Questions
Is bonus depreciation 100% in 2026?
Generally, yes, for qualifying property acquired and placed in service after January 19, 2025. Older acquisition arrangements and certain excluded property require separate review. The former phase-down schedule should not be applied automatically to a new 2026 purchase.
Can I use Section 179 and bonus depreciation on the same equipment?
Yes, when the property qualifies for both. Section 179 is applied first, followed by bonus depreciation on eligible remaining basis, then regular depreciation where applicable. You cannot deduct the same cost twice.
Is Section 179 better than bonus depreciation?
Neither is always better. Section 179 can offer more control over selected assets and amounts. Bonus depreciation can be useful when Section 179’s income or spending limits restrict the deduction. State treatment and the timing of usable tax savings also matter.
Can I deduct used equipment?
Potentially. Both provisions can apply to qualifying used equipment, but the seller relationship, prior use, and acquisition details need review. Buying used does not, by itself, disqualify a purchase.
Do I have to spend money before year-end to lower my taxes?
An equipment purchase is only one planning option. Start with an updated tax projection and your business needs. Spending money on something you do not need can leave you with less cash even after the tax savings.
Make the Equipment Decision and the Tax Decision Together
The right answer to bonus depreciation vs. Section 179 in 2026 depends on more than the deduction shown on a worksheet. It depends on whether the equipment qualifies, when it will be available, how the deduction affects your returns, and what the purchase leaves in your bank account.
A business equipment tax deduction can make a necessary investment more affordable. It should support a sound business decision.
