You may see bonus depreciation referred to as the special allowance, the additional first-year deduction, or IRC §168 (k) depreciation. Congress created this deduction to stimulate business activity by encouraging business owners to purchase qualifying assets. Without the use of a special accelerated depreciation method, the deduction for the purchase of a business asset would generally need to be apportioned over the course of multiple tax periods.
How Bonus Depreciation Works
Business owners can claim 100% bonus depreciation on property placed in service before 2023. For property placed in service in 2023 and beyond, the following bonus depreciation rate applies:
| Year the asset was placed in service | Bonus depreciation rate |
|---|---|
| 2023 | 80% |
| 2024 | 60% |
| 2025 | 40% |
| 2026 | 20% |
| After 2026 | 0% |
Bonus depreciation applies to new or used qualified property. Under IRS guidelines, qualified business property is MACRSModified Accelerated Cost Recovery System property with a recovery period of 20 years or less, depreciable computer software, water utility property, or qualified improvement property.
The following property qualifies for bonus depreciation:
- Office furniture includes desks, files, safes, communications equipment, and similar items.
- Information systems include computers and peripheral equipment—such as card readers, printers, projectors, and disc drives—used in conducting normal business activity.
- Vehicles include cars, trucks, vans, and even over-the-road semis; however, bonus depreciation on passenger automobiles that weigh 6,000 pounds or less is limited to $8,000.
The following does not qualify for bonus depreciation:
- Non-MACRS property includes vehicles where the standard mileage deduction is being used.
- Property used outside of the US includes qualified improvement property relating to property used outside of the US.
- Property used by a tax-exempt entity includes, specifically, property leased to a tax-exempt entity.
- Property with insufficient business use– specifically property with less than 50% business use.
For a more detailed list of MACRS properties, check out IRS Publication 946.
See examples of how bonus depreciation could play out with MACRS property.
- Example 1: In January 2024, Bob Builder purchased office furniture for $500 for their new construction firm. Office furniture is a seven-year MACRS property, and they’re claiming 60% bonus depreciation since it was purchased in 2024. They do not have any other applicable credits or deductions, so they can claim a $300 ($500 × 60%) bonus depreciation deduction when they file their 2024 tax return. In addition to the bonus depreciation, Bob Builder can claim regular MACRS depreciation over seven years for the remaining cost of $200.
- Example 2: Let’s use the same facts as above, but Bob Builder claims $100 of Section 179 on the office furniture. Bob can now claim bonus depreciation of 60% of the remaining $400 cost, or $240. So, in total, they can deduct $100 of Section 179, $240 of bonus depreciation, plus regular MACRS depreciation over seven years on the remaining $160 of cost.
Maximizing Bonus Depreciation With a Cost Segregation Analysis
If you’re a business owner who owns property such as a warehouse, office building, or residential rental property, then you may benefit from a cost segregation analysisCost segregation studies are in-depth analyses of the cost of components and fixtures inside of buildings. These studies are typically performed by a qualified individual such as an engineer, appraiser, or contractor. . By segregating the cost of MACRS property with shorter lives from the cost of the building, you can claim bonus depreciation on the individual components of property. This allows for equipment, furniture, and fixtures—such as HVAC systems—to be eligible for bonus depreciation.
During the study, the components that make up the building will be analyzed and given a recovery period of five, seven, or 15 years. This can be a great strategy to help you take advantage of the bonus depreciation deduction, create tax savings, and increase your cash flow.
Pros & Cons of Bonus Depreciation
| PROS | CONS |
|---|---|
| Creates a tax savings by reducing your taxable income and overall tax liability | Doesn’t let you pick which assets to claim bonus depreciation on; all assets within a class life must be treated the same |
| Creates a large deduction in the year of purchase even if financed over multiple years | Is scheduled to phase out by 2027 |
| Is available for new and most used property and some building improvements | Is unideal in situations where the taxpayer has expiring carryforward credits or deductions they need to use; bonus depreciation will decrease income needed to absorb the other income reductions |
| Is not limited to taxable income or a maximum deduction the way other accelerated methods are, like Section 179 | |
How to Calculate Bonus Depreciation
You can calculate bonus depreciation by following this process:
- Step 1: Reduce the original cost by any section 179 expense deducted for the year. Original cost includes line items such as sales tax and delivery fees.
- Step 2: Further reduce the cost by any credits you claimed (e.g., energy credit).
- Step 3: Multiply the bonus rate of 60% for 2024 (80% for 2023) by the remaining cost of the asset.
The product will yield the amount of bonus depreciation you can claim for the tax year.

Election to Opt Out of Bonus Depreciation
While it’s generally beneficial for you to speed up depreciation, you do have the option of opting out of bonus depreciation. If you have expiring charitable deduction carryforwards or credit carryforwards, you may decide to opt out.

1. Do nothing and claim 60% bonus depreciation for 2024.
By doing nothing, you’ll automatically claim 60% bonus depreciation on your 2024 tax return for property that you have placed in service during the 2024 tax year.
2. Attach an election to not use any bonus depreciation.
You can opt out of claiming bonus depreciation and instead calculate your depreciation under the normal MACRS rules. The election is made separately for each asset class.
