Section 179 Business Tax Deduction
Section 179 Deduction at a Glance for 2025
What is the Section 179 Deduction?
Most people think the Section 179 deduction is some mysterious or complicated tax code. It really isn’t, as you will see below.
Essentially, Section 179 of the IRS tax code allows businesses to deduct the full purchase price of qualifying equipment and/or software purchased or financed during the tax year. That means that if you buy (or lease) a piece of qualifying equipment, you can deduct the FULL PURCHASE PRICE from your gross income. It’s an incentive created by the U.S. government to encourage businesses to buy equipment and invest in themselves.
Several years ago, Section 179 was often referred to as the “SUV Tax Loophole” or the “Hummer Deduction” because many businesses have used this tax code to write-off the purchase of qualifying vehicles at the time (like SUV’s and Hummers). But that particular benefit of Section 179 has been severely reduced in recent years (see ‘Vehicles & Section 179’ for current limits on business vehicles.)
However, despite the SUV deduction lessened, Section 179 is more beneficial to small businesses than ever. Today, Section 179 is one of the few government incentives available to small businesses, and has been included in many of the recent Stimulus Acts and Congressional Tax Bills. Although large businesses also benefit from Section 179 or Bonus Depreciation, the original target of this legislation was much needed tax relief for small businesses – and millions of small businesses are actually taking action and getting real benefits.
Here's How Section 179 works:
In years past, when your business bought qualifying equipment, it typically wrote it off a little at a time through depreciation. In other words, if your company spends $50,000 on a machine, it gets to write off (say) $10,000 a year for five years (these numbers are only meant to give you an example).
Now, while it’s true that this is better than no write-off at all, most business owners would really prefer to write off the entire equipment purchase price for the year they buy it.
And that’s exactly what Section 179 does – it allows your business to write off the entire purchase price of qualifying equipment for the current tax year.
This has made a big difference for many companies (and the economy in general.) Businesses have used Section 179 to purchase needed equipment right now, instead of waiting. For most small businesses, the entire cost of qualifying equipment can be written-off on the 2025 tax return (up to $1,250,000).
2025 Deduction Limit = $1,250,000
This deduction is good on new and used equipment, as well as off-the-shelf software. To take the deduction for tax year 2025, the equipment must be financed or purchased and put into service between January 1, 2025 and the end of the day on December 31, 2025.
2025 Spending Cap on equipment purchases = $3,130,000
This is the maximum amount that can be spent on equipment before the Section 179 Deduction available to your company begins to be reduced on a dollar for dollar basis. This spending cap makes Section 179 a true “small business tax incentive” (because larger businesses that spend more than $3,780,000 on equipment won’t get the deduction.)
Bonus Depreciation: 40% for 2025
Bonus depreciation is similar to the Section 179 tax deduction in that it offers an immediate expense deduction. However, the primary difference is that bonus depreciation lets you deduct a percentage of qualifying equipment upfront while, as mentioned earlier, Section 179 enables you to deduct a specific dollar amount. Bonus depreciation applies to many types of new and used equipment with a useful life of up to 20 years.
In 2025, the bonus depreciation amount is 40% and is scheduled to decrease to 20% in 2026.2 So, if you procure qualifying equipment in 2025, you can deduct a higher percentage of the purchase price on your 2025 tax return, provided you put the equipment into business use before the deadline. For example, a $70,000 equipment purchase in 2025 would have a first-year depreciation of $28,000 ($70,000 x 40%). If the $70,000 equipment purchase is made in 2026, the first-year depreciation is $14,000 ($70,000 x 20%).
Vehicles and Section 179
One of the more popular uses of the Section 179 Deduction has been for vehicles. In fact, several years ago the Section 179 deduction was sometimes referred to as the “Hummer Tax Loophole,” because at the time it allowed businesses to buy large SUV’s and write them off. While this particular use (or abuse) of the tax code has been modified with the limits explained below, it is still true that Section 179 can be advantageous in buying vehicles for your business.
Vehicles used in your businesses qualify – but certain passenger vehicles have a total deduction limitation of $11,160, while other vehicles that by their nature are not likely to be used more than a minimal amount for personal purposes qualify for full Section 179 deduction (full policy statement available at: IRS.gov ).
What Business Vehicles Qualify for the full Section 179 Deduction?
Note that because many vehicles can serve business and personal function both, the rules for business vehicle deductions are always evolving, and can be complicated. It’s easier to list the typical vehicles that will generally qualify for a full section 179 deduction, and then discuss the rules for other vehicles.
Many “work vehicles” that, by their nature, are not likely to be used for personal purposes will usually always qualify for full Section 179 deduction. This includes the following vehicles:
- Vehicles that can seat nine-plus passengers behind the driver’s seat (i.e.: Hotel / Airport shuttle vans, etc.).
- Vehicles with: (1) a fully-enclosed driver’s compartment / cargo area, (2) no seating at all behind the driver’s seat, and (3) no body section protruding more than 30 inches ahead of the leading edge of the windshield. In other words, a classic cargo van.
- Heavy construction equipment will qualify for the Section 179 deduction, as will forklifts and similar.
- Typical “over-the-road” Tractor Trailers will qualify.
Limits for SUVs or Crossover Vehicles with GVW above 6,000lbs
Certain vehicles (with a gross vehicle weight rating above 6,000 lbs. but no more than 14,000 lbs.) qualify for deducting up to $25,000 if the vehicle is purchased and placed in service prior to December 31 and meets other conditions.
Limits of Section 179
Section 179 does come with limits – there are caps to the total amount written off ($1,250,000 for 2025), and limits to the total amount of the equipment purchased ($3,130,000 in 2025). The deduction begins to phase out on a dollar-for-dollar basis after $3,130,000 is spent by a given business (thus, the entire deduction goes away once $3,130,000 in purchases is reached), so this makes it a true small and medium-sized business deduction.
Who Qualifies for Section 179?
All businesses that purchase, finance, and/or lease new or used business equipment during tax year 2025 should qualify for the Section 179 Deduction (assuming they spend less than $3,130,000).
Most tangible goods used by American businesses, including “off-the-shelf” software and business-use vehicles (restrictions apply) qualify for the Section 179 Deduction.
For basic guidelines on what property is covered under the Section 179 tax code, please refer to this list of qualifying equipment. Also, to qualify for the Section 179 Deduction, the equipment and/or software purchased or financed must be placed into service between January 1, 2025 and December 31, 2025.
For 2025, $1,250,000 of assets can be expensed; that amount phases out dollar for dollar when $3,130,000 of qualified assets are placed in service.
What's the difference between Section 179 and Bonus Depreciation?
Bonus depreciation is offered some years, and some years it isn’t. Right now in 2025, it’s being offered at 40%.
The most important difference is both new and used equipment qualify for the Section 179 Deduction (as long as the used equipment is “new to you”), while Bonus Depreciation has only covered new equipment only until the most recent tax law passed. In a switch from recent years, the bonus depreciation now includes used equipment.
Bonus Depreciation is useful to very large businesses spending more than the Section 179 Spending Cap (currently $3,130,000) on new capital equipment. Also, businesses with a net loss are still qualified to deduct some of the cost of new equipment and carry-forward the loss.
When applying these provisions, Section 179 is generally taken first, followed by Bonus Depreciation – unless the business had no taxable profit, because the unprofitable business is allowed to carry the loss forward to future years.
What's the difference between Section 179 and Bonus Depreciation?
The equipment, vehicle(s), and/or software must be used for business purposes more than 50% of the time to qualify for the Section 179 Deduction. Simply multiply the cost of the equipment, vehicle(s), and/or software by the percentage of business-use to arrive at the monetary amount eligible for Section 179.

Other Considerations
Vehicles can be new or used (“new to you” is the key). The vehicle must be acquired in an “arms-length” transaction, financed with certain qualified leases and loans, and titled in the company name (not in the company owner’s name).
The vehicle must also be used for business at least 50% of the time – and these depreciation limits are reduced by the corresponding % of personal use if the vehicle is used for business less than 100% of the time.
Remember, you can only claim Section 179 in the tax year that the vehicle is “placed in service” – meaning when the vehicle is ready and available – even if you’re not using the vehicle. Further, a vehicle first used for personal purposes doesn’t qualify in a later year if its purpose changes to business.
As always, if you have questions, consult your tax professional for exact rules regarding Section 179 and vehicles.
