Section 179 Makes Buying Equipment Look Smart. Here Is When It Drains Your Cash Instead.
On this page
Section 179 lets a business deduct the cost of qualifying equipment in the year it is placed in service, and for taxable years beginning in 2026 the limit is $2,560,000, phasing out once qualifying purchases exceed $4,090,000, under Rev. Proc. 2025-32. The deduction is real; the cash is still spent. Assume a 24% combined marginal tax rate: a $100,000 excavator bought for cash saves about $24,000 of tax while $100,000 leaves the account. The purchase has to make sense before the deduction, or the deduction only softens a cash problem it helped create.
Should the Deduction Drive the Purchase?
| Section 179 tends to help when | Section 179 tends to hurt when |
|---|---|
| The equipment is needed for the work regardless of tax | The purchase is mainly a way to lower a tax bill |
| Business taxable income can absorb the deduction | A thin year leaves too little income to use it |
| Cash reserves are strong, or financing protects cash | Paying cash before a slow season strains payroll |
| The equipment will stay in business use above 50% | Business use may drop to 50% or less, triggering recapture |
If the purchase only makes sense because of the deduction, that is the signal to stop.
The 2026 Numbers
For taxable years beginning in 2026, Rev. Proc. 2025-32 sets three figures under section 179(b):
- Maximum deduction: $2,560,000.
- Phase-out threshold: the limit is reduced, but not below zero, by the amount by which the cost of section 179 property placed in service during the year exceeds $4,090,000. At $6,650,000 of qualifying purchases, the reduction equals the full $2,560,000.
- Sport utility vehicles: the cost of a sport utility vehicle that may be taken into account under section 179 cannot exceed $32,000.
These amounts adjust each year, so a purchase planned near a year boundary is governed by the revenue procedure for the year the equipment is placed in service.
Bonus Depreciation Sits Beside It
Bonus depreciation under section 168(k) is a separate first-year deduction. Notice 2026-11 explains that the 2025 legislation, Public Law 119-21, replaced the phase-down with “a permanent 100 percent additional first year depreciation deduction for qualified property acquired … after January 19, 2025.” The notice is interim guidance ahead of proposed regulations.
The three first-year tools apply in a fixed order. IRS Publication 946 describes bonus depreciation as “an additional deduction you can take after any section 179 deduction and before you figure regular depreciation under MACRS for the year you place the property in service,” and notes that if only part of the cost is deducted under section 179, “you can generally depreciate the cost you do not deduct.” So the sequence on any asset is:
- Section 179 on the amount the business elects, within the dollar limit and the business income limit below.
- Bonus depreciation on the remaining basis of qualified property.
- Regular MACRS depreciation on whatever basis is left, over the recovery period the IRS tables in Publication 946 assign to that class of property.
Electing less under Section 179 does not, by itself, push the deduction into later years. With 100% bonus depreciation available for qualified property, whatever basis Section 179 leaves behind is generally deducted in the same year as bonus depreciation. To spread the deduction instead, the business has to elect out of bonus depreciation, and Publication 946 says that election is made “for any class of property,” covering all property in that class placed in service during the year, by a statement attached to a timely filed return. Only then does regular MACRS depreciation carry the remaining basis over the recovery period. Spreading can matter when a business expects higher income ahead or cannot absorb a full first-year deduction, but it is a class-wide choice with its own consequences for every asset in that class, and the right mix for a given year is a CPA’s call.
The Trap: A Deduction Is Not Cash
Run the $100,000 excavator three ways, with the same 24% assumed rate:
| Approach | Cash out in year one | Federal tax effect | Financial statements |
|---|---|---|---|
| Buy with cash, deduct under Section 179 | $100,000 | About $24,000 less tax in year one | Equipment asset, depreciated over its useful life |
| Finance the purchase, deduct under Section 179 | Down payment and loan payments | About $24,000 less tax in year one, if the business is treated as the owner | Equipment asset and a loan liability |
| Operating lease | Lease payments | Lease payments deducted under the business's tax method, no Section 179 | Right-of-use asset and lease liability under ASC 842, unless the lease is 12 months or less and the business elects to exclude such leases |
Buying with cash in December spends $100,000 to save about $24,000, and the $76,000 difference leaves just before the months when payroll still has to be met. Financing keeps the tax benefit while spreading the cash, but the loan is a liability that changes the working-capital and debt ratios lenders and sureties read. Under an operating lease, the lessor keeps the incidents of ownership; Publication 946 says leased property can be depreciated only by the party that retains them, so the lessee deducts its lease payments instead. That is the tax picture, not the balance sheet. Under the lease accounting standard in ASU 2016-02 (ASC 842), a lessee with an operating lease must recognize a right-of-use asset and a lease liability, “initially measured at the present value of the lease payments,” with a policy election under 842-20-25-2 for leases of 12 months or less. A multi-year equipment lease therefore still adds a liability that lenders and sureties see. Whether a particular finance or lease agreement treats the business as the owner for tax purposes is a determination to make with a CPA before signing.
The Business Income Limit
Section 179 cannot create a loss. Publication 946 says the total cost deductible each year, after the dollar limit, “is limited to the taxable income from the active conduct of any trade or business during the year,” and that cost not deductible because of this limit carries over to later years. The limit applies to each taxpayer, not each business, so an owner’s other business income and losses matter.
The contractor most tempted to buy equipment to wipe out a tax bill in a thin year may be the one whose income cannot absorb the deduction, while the contractor with a strong year is both able to use it and able to afford the purchase. Check the income figure before signing for the equipment.
Two Timing Rules
Placed in service. The deduction belongs to the year the equipment is placed in service, and Publication 946 defines that as when property “is ready and available for a specific use.” An excavator ordered in December and delivered in January is a next-year deduction, whatever date the deposit cleared.
Business use and recapture. Section 179 requires business use above 50% in the year the property is placed in service. If business use later drops to 50% or less during the property’s recovery period, Publication 946 says “you include the recapture amount as ordinary income” in that year. A truck expensed in a busy year and shifted to mostly personal use later brings part of the deduction back.
The Florida Corporate Add-Back
Florida has no personal income tax, so an owner who reports business income only on a personal return is planning against the federal deduction alone. A business subject to Florida’s corporate income tax faces a different rule. Section 220.13, Florida Statutes requires an add-back of 100% of federal bonus depreciation deducted under section 168(k) for property placed in service before January 1, 2027, and then a subtraction of one-seventh of the added amount in that year and in each of the six following years. That seven-year recovery does not cover every bonus amount: section 220.13(1)(e)1.c excludes bonus depreciation on qualified improvement property from it, and subparagraph 5 of the same paragraph sets separate rules for qualified improvement property placed in service on or after January 1, 2018. The statute’s Section 179 add-back applies only to taxable years beginning after December 31, 2007, and before January 1, 2015. How Florida treats bonus depreciation under the 2025 federal amendments and for property placed in service in 2027 or later is a question for a CPA reading the statute in force that year.
How the Purchase Lives in the Books
Equipment bought is a fixed asset on the balance sheet, depreciated in the financial statements over its useful life even when Section 179 deducts it all for tax. The resulting book-tax difference is normal and belongs in the year-end reconciliation. A financed purchase adds a loan and an interest expense, recorded separately from the equipment; the loan principal is neither an expense nor a deduction. An operating lease is recorded as the lease agreement and the accounting framework require, not as owned equipment. Clean fixed-asset records, a loan schedule, and the tax depreciation elections kept side by side are what keep the equipment decision from muddying the financial statements a bank or surety reads. The same depreciation, interest, and operating costs also feed the internal equipment rate charged to jobs, so the machine’s cost lands on the work that uses it.
The Order of Questions
- Does the work need this equipment, regardless of tax?
- Will it stay in business use above 50% for its recovery period?
- Can the business pay for it, or should financing protect the cash through the next slow season? A 13-week cash forecast run with and without the purchase answers this one.
- Does this year’s business income absorb the deduction, and is Section 179, bonus depreciation, or regular depreciation the better mix this year?
- If the business pays Florida corporate income tax, what does the add-back do to the state result?
Answered in that order, Section 179 rewards a purchase the business needed anyway. Answered backward, starting from the tax bill, it is how a profitable year ends with too little cash.
