The December Deadline Moved: Section 179, Permanent Bonus Depreciation, and the New Year-End Urgency in Equipment Financing

For 2026, the Section 179 deduction caps at $2,560,000, phasing out dollar for dollar above $4,090,000 of qualifying property, and 100% bonus depreciation is now permanent with no scheduled step-down. That second fact quietly killed the year-end pitch the equipment finance industry has leaned on since the phase-down began in 2023. There is no longer a depreciation percentage to beat by buying before January. What remains, and what almost nobody's script reflects, is the deadline that was always underneath: the equipment has to be placed in service by December 31 to count against this year's taxes, and for a growing list of equipment types, delivery is the constraint. The tax conversation in 2026 is a lead-time conversation.

This matters to anyone selling equipment financing, because "buy before the deadline" was the most reliable urgency line in the industry, and the deadline it pointed at is gone. Here is what replaced it, with every number sourced.

What changed: 100% bonus depreciation is permanent

Under prior law, bonus depreciation was stepping down on a schedule: 60% in 2024, 40% in 2025, 20% in 2026, zero after. Every year-end campaign in the industry was built on that staircase. "Lock in this year's percentage before it drops."

The One Big Beautiful Bill Act ended the staircase. For qualifying property acquired after January 19, 2025, the deduction is 100% of cost in the year the property is placed in service, permanently. No phase-down, no sunset date, nothing to beat by acting in December instead of March. (IRS Notice 2026-11, RSM summary)

A business buying a $400,000 excavator in 2026 can generally expense the full $400,000 this year whether the deal closes in February or November. The calendar-based scarcity that drove ten years of Q4 campaigns does not exist anymore.

The 2026 Section 179 numbers

Section 179 still matters, especially for smaller businesses and for its own set of reasons (it can apply where bonus rules get complicated, and some states treat the two differently). The 2026 figures, verified against Rev. Proc. 2025-32, section 4.24:

• Deduction limit: $2,560,000
• Phase-out threshold: $4,090,000. Above that, the deduction shrinks dollar for dollar, reaching zero at $6,650,000 of qualifying property placed in service.
• Sport utility vehicle cap: $32,000 per vehicle.

Two mechanics worth stating precisely, because most year-end marketing gets them loose:

1. Placed in service, not ordered and not financed: the deduction attaches when the equipment is delivered and running. A signed finance agreement in November for a machine that delivers in February is a 2027 deduction, not a 2026 one.
2. Financed equipment qualifies in full: a business that puts 10% down on a $500,000 machine and places it in service by December 31 generally deducts against the full $500,000, not the down payment. This has always been the strongest tax argument for financing over waiting to pay cash, and it survives every change above.

The old pitch vs the new pitch

Same urgency. Different reason. The reps still running the old script are creating urgency their customer's accountant will contradict in one phone call.

Why the deadline is now a lead-time problem

The placed-in-service rule only bites when delivery takes a long time, and in several equipment categories right now, it does.

Trucking is the loudest example. North American Class 8 net orders hit roughly 30,500 units in June by FTR's preliminary count, up more than 240% year over year against a weak 2025 comp. (CCJ) A month earlier, FTR had already reported 2026 build slots "on track to sell out before the typical August window," with the risk shifting "from generating orders to filling them." (FTR) A carrier that decides in October it wants trucks running by December 31 is probably not having a tax conversation. If FTR's forecast holds, it is having a "there are no trucks" conversation.

The same logic applies at smaller scale anywhere backlogs exist: specialized vocational builds, some machine tools, anything requiring installation and commissioning before it counts as in service. The question that matters is no longer "can we close by December" but "what is the last order date that still delivers this year," and that date arrives months earlier than most year-end campaigns start.

What this means if you sell equipment financing

The practical read for a lender or broker sales team:

The year-end campaign has to move up. If the last honest order date for a customer's equipment is September or October, then the "year-end push" that starts in November is a campaign about next year's taxes. The teams that fund the Q4 wave are the ones talking to buyers now, in August, while a this-year delivery is still physically possible.

The urgency line changes. Not "the deduction steps down," which is now false, but "the deduction requires delivery, and delivery requires a slot." That line has the advantage of being true, checkable, and something the customer's dealer will confirm.

The target list changes. The old pitch could be sprayed at anyone with taxable income. The new pitch only lands with companies that are actually near an equipment decision with a delivery clock attached: fleets adding capacity, contractors with awarded work starting this fall, shops replacing machines with long build times. Figuring out which companies those are before the competition calls them is exactly the kind of public-records problem we built Quintel to solve, and it is the difference between a rep making tax-deadline small talk and a rep calling the twenty companies whose window actually closes this year.

The fine print

Three caveats worth knowing before this goes in anyone's customer email, because the buyer's CPA will know them:

• The acquisition date: property acquired before January 20, 2025 stays on the old TCJA phase-down schedule even if placed in service later. The permanent 100% rate applies to property acquired after January 19, 2025. (IRS Notice 2026-11)
• A transition election: for qualified property placed in service in the taxpayer's first tax year ending after January 19, 2025, a taxpayer could elect 40% (or 60% for certain longer-production property) instead of 100%. Edge case, but real.
• State conformity: a number of states decouple from federal bonus depreciation or cap Section 179 differently, so the federal math above does not automatically hold on a state return.

None of this is tax advice, and the close on any deal should involve the customer's own tax professional. The point is narrower: the federal deadline structure that powered the industry's default urgency pitch changed, and the scripts have not.

FAQ

Is bonus depreciation 100% in 2026?

Yes. For qualifying property acquired after January 19, 2025 and placed in service in 2026, the additional first-year depreciation deduction is 100% of cost, and it is permanent under current law, with no scheduled phase-down.

What is the Section 179 limit for 2026?

$2,560,000, with a phase-out beginning at $4,090,000 of qualifying property placed in service. The SUV cap is $32,000 per vehicle. Source: Rev. Proc. 2025-32.

Does financed equipment qualify for Section 179 and bonus depreciation?

Generally yes. The deduction is based on the cost of the qualifying equipment, not the cash paid in the year. A financed machine placed in service by December 31 can typically be deducted in full this year even if payments run for years.

What does "placed in service" mean?

Ready and available for its intended use. Delivered, installed where installation is required, and in a condition to operate. An ordered machine, or a signed finance agreement for one, is not placed in service.

When is the real deadline to buy equipment for a 2026 deduction?

Whenever an order can still be delivered and running by December 31. For equipment with long build or delivery times, that date can fall in late summer or early fall, months before the calendar deadline.
