How Bonus Depreciation & Section 179 Work Together

Business equipment is generally treated as a capital asset, and depreciation allows a business to recover its cost through tax deductions spread over time. If you need a quicker, larger write-off, there are two accelerated options that can work together to maximize savings:

  1. Section 179, which allows qualifying businesses to expense some or all of the cost immediately, subject to limits.
  2. Bonus Depreciation, which allows qualifying property to be fully depreciated in the first year.
Section 179Bonus Depreciation
What it does Allows immediate expensing of qualifying propertyAccelerates depreciation into the first year
2026 Threshold$2.56 million*100% for qualifying property**
PhaseoutYesNo comparable overall dollar phaseout
Taxable income limitationYes. It cannot create a net loss for your businessCan create or increase a net operating loss
Control & selectionYou can choose which specific assets to apply it to and how much of a deduction to takeTypically all-or-nothing automatic application (unless you explicitly elect out of it)

*The Section 179 maximum for 2026 is $2.56 million, reducing once qualifying property placed in service exceeds $4.09 million.
**The property must qualify for Bonus Depreciation, and other tax rules still matter.


  • When you need flexibility to precisely target a specific net income number
  • If your state disallows bonus depreciation
  • If you need a first-year write-off
  • If you want to intentionally create a net loss
  • To avoid spending and purchasing caps
  • When you want to apply the deduction automatically to all qualifying property

When using both on your tax return, the IRS requires you to apply Section 179 first, then apply bonus depreciation to any remaining cost over the $2.56M threshold. If your business purchases more than that limit in qualifying equipment, you can use bonus depreciation to deduct 100% of the remaining balance with no overall dollar limit.

The IRS notes that property can be considered owned for depreciation purposes even when it’s subject to debt. What this means is that you may be able to finance qualifying equipment and still take advantage of applicable depreciation deductions, provided the tax requirements are met! Here’s what your first year investment could look like with both options:

$100,000 equipment
$100,000 cash leaves the business

$100,000 equipment
$2,000 monthly payment
Preserve working capital (cash on hand)
Same depreciation treatment!


Remember, tax deduction ≠ tax credit.

A $100,000 deduction does not mean the government sends you $100,000. Instead, it’s a reduction in taxable income. Your actual tax savings will depend on your unique circumstances and tax rate.

Also, equipment needs to not only be purchased but also placed in service – ready and available for its intended business use – in the year you plan to use the deduction(s). If you’re considering equipment for your business, don’t wait until December! Financing, delivery and install, and gettin the equipment ready to be used take time.

For the current IRS rules and limitations, see the IRS’s Section 179 guidance (scroll down the left menu to the Section 179 section). Geneva Capital can help find a structure to fit your needs, but you should also consult your tax advisor when weighing your tax options and making purchasing decisions.
