What is bonus depreciation?

Written by John Kirkland | May 06, 2025

When a business entity, especially a smaller one, makes a major purchase of a depreciable asset—like restaurant equipment, new computer system, delivery truck, office furniture—it can be a big hit on their wallet, or saddle them with burdensome debt. 

In 2017, Congress passed the Tax Cuts and Jobs Act, creating a tax incentive that allows businesses to deduct a larger depreciation expense on capital assets purchased, affording them more immediate tax relief.  

They called it Bonus Depreciation. 

In this article, we define just what bonus depreciation is, what assets qualify for it, how much additional depreciation you can write off, how it differs from Section 179 depreciation, and potential drawbacks to taking it.  

What exactly is bonus depreciation? 

To encourage more investment in capital assets, bonus depreciation allows businesses to deduct a larger percentage of the cost of eligible business property in the year it is placed in service. The faster write-off is in addition to the asset’s regular depreciation. 

This welcome provision is a boon to many small businesses, since the accelerated depreciation schedule immediately reduces their tax liability and makes it easier to acquire the assets that can help grow their business. 

Assets that qualify for bonus depreciation 

Bonus depreciation typically applies to tangible property, including vehicles, equipment, machinery, furniture, and certain types of real property improvements.  

Only depreciable assets are eligible and must have a useful life of 20 years or less. 

This includes what the IRS defines as “listed property,” or property purchased for both personal and business use, provided more than 50% is used for business purposes (measured in time, mileage, or other relevant metric). Among these assets are: 

  • Modified Accelerated Cost Recovery Systems (MACRS) assets like office furniture, computers, software, cell phones, etc. 
  • Short-term rental properties, including vacation properties where the average stay is 7 days or fewer.  
  • Certain film, TV and live theatrical productions 
  • Passenger cars 
  • Certain work trucks and vans  
  • Other capital assets used for transportation 
  • Property used for entertainment, recreation or amusement 
  • And used property (a welcome change from previous depreciation rules) 

What about leases? Are they eligible? 

Finance or capital leases transfer ownership of the underlying asset from the lessor to the lessee, who is entitled to various tax benefits, including bonus depreciation.  

An operating lease, however, permits the use of an asset without transferring ownership rights. Thus, the lessee cannot claim bonus depreciation, but the lessor can. 

Assets that don’t qualify 

Other assets that aren’t eligible for the bonus write-off include residential rental property, assets that don’t lose their value over time, and those you are not currently using to create income—for example, land, art collectibles, coins, and memorabilia.  

Amount of bonus depreciation you can take 

Since its enactment in 2017, when bonus depreciation amounted to 100% of a qualifying asset’s cost, the additional percentage you can deduct is being slowly phasing out. 

For the 2024 tax year, you can take an extra 60% depreciation expense; in 2025 that number will decline to 40%; in 2026 it goes down to 20%, and for 2027 and beyond, 0%.  

💰To benefit from the law before it expires, and enjoy a sizable reduction in your taxes, make those capital purchases sooner than later.  


Bonus depreciation has no annual cap in actual dollars on the amount of your deduction. Because there’s no limit, you can take an operating loss that can carry forward in subsequent years to offset future income.
 

Section 179 vs. bonus depreciation 

What’s the difference? Which is better?  

  • Section 179 of the tax code allows business taxpayers to deduct the cost of certain property as an expense when the property is first placed in service.  
  • Like bonus depreciation, office furniture, certain vehicles, computer equipment, off-the-shelf software, and other depreciable assets qualify for the write-offs. The difference is, bonus depreciation is computed as a percentage of an asset’s cost, while Section 179 allows a set dollar amount. 
  • That difference can be significant since there’s no total dollar limit on bonus depreciation, but a $1,220,000 ceiling on Section 179 for 2024, and $1,250,000 for 2025. 
  • Another notable difference: work trucks and vans with a gross vehicle weight rating of over 6,000 lbs. are eligible for bonus depreciation, while Section 179 requires them to be under 6,000 lbs. 
  • Also, with Section 179 a business cannot deduct more than its annual taxable income; bonus depreciation has no limit so it can be used to create a net loss.  

So, any downsides to bonus depreciation? 

As discussed, bonus depreciation can offer small businesses some big tax relief. Yet there are a few caveats you should be aware of: 

  • If you claim bonus depreciation, you may be subject to depreciation recapture if you sell the asset and have to pay back a percentage of its value. 
  • Taking it now won’t allow you to offset higher income with a greater depreciation expense in a later year. (But keep in mind the percentage allowed decreases yearly.) 
  • Depreciation lowers the “basis” of your asset. That could come back to bite you if, let’s say, you sell your heavily depreciated van at a tidy profit and have to pay a lot more in taxes than you originally had anticipated.
  • Accelerating depreciation lowers your asset’s book value. That can affect your balance sheet and your ability to borrow money against it. 

The bottom line 

Bonus depreciation offers attractive financial benefits if you’re trying to expand your small business, would like to make major asset purchases, and don’t want to be hit with high taxes at a time when that money could be put to better use. 

But since bonus depreciation will be nonexistent by the tax year 2027, and its write-off percentage is declining each year, the time to take advantage of it is ASAP.  

Yes, it can all be complicated and confusing. That’s why here at DiMercurio Advisors we make it our mission to fully master such tax issues to give you the best advice possible on how to proceed.
