Bonus Depreciation

Bonus depreciation is a tax incentive that enables businesses to accelerate depreciation deductions by allowing them to deduct a significant portion—or even 100% in recent years—of the cost of qualified property in the year the asset is placed in service. This approach contrasts the traditional depreciation method, which spreads deductions over the asset’s useful life. The goal is to encourage businesses to invest in equipment and other assets that can improve operations and growth.

How Bonus Depreciation Works

When a business purchases qualified tangible property like machinery, equipment, or certain improvements to nonresidential real estate, it can claim bonus depreciation in the year the asset is ready for use. For example, if a business buys equipment costing $10,000 and places it in service in 2023, it might deduct 80% ($8,000) immediately, rather than depreciating the cost over several years.

The IRS requires the asset to be placed in service during the tax year to qualify. ‘‘Placed in service’’ means the asset is available and ready for its intended business use, not just purchased.

To claim the deduction, businesses file IRS Form 4562, which reports depreciation and amortization.

History and Recent Changes

Introduced in 2002 to stimulate economic activity, bonus depreciation initially allowed a 30% immediate deduction. It was gradually increased and broadened.

The Tax Cuts and Jobs Act (TCJA) of 2017 made a significant change by allowing 100% bonus depreciation for qualified assets acquired and placed in service after September 27, 2017, through December 31, 2022. Crucially, TCJA also extended eligibility to used property if certain conditions were met.

Since 2023, this 100% rate is phasing down as follows:

This phase-out requires careful tax planning for asset acquisitions.

Eligibility Criteria

To qualify for bonus depreciation:

• Property must be tangible, depreciable, with a recovery period of 20 years or less.
• It can be new or used, as long as the used property was not previously used by the taxpayer and is not acquired from related parties.
• The property must be placed in service during the tax year.
• Property such as land or buildings themselves generally does not qualify, although qualified improvement property (e.g., interior building improvements) may be eligible.
• The asset must be used predominantly for business purposes; partial business use limits the allowable deduction accordingly.

Strategic Benefits

Bonus depreciation helps reduce taxable income immediately, freeing cash for business reinvestment. It can result in net operating losses, which may be carried forward to offset future tax years, providing flexible tax planning opportunities.

Businesses often use bonus depreciation in conjunction with the Section 179 deduction, another method for accelerated asset expensing, but with different limits and rules. Consulting a tax professional ensures the best strategy.

Common Pitfalls to Avoid

• Mistaking the purchase date for the placed-in-service date could cause incorrect deduction timing.
• Assuming all assets qualify can lead to IRS issues; always verify property eligibility.
• Forgetting the phase-out schedule and tax year rules may reduce expected benefits.
• Confusing bonus depreciation with Section 179 deduction limits and qualifications.

Practical Examples

Maria’s Bakery: Maria buys a $30,000 oven in late 2023 and applies 80% bonus depreciation, deducting $24,000 immediately and depreciating the rest over the oven’s lifespan.

David’s IT Firm: David buys $15,000 in furniture and computer equipment in 2024. With 60% bonus depreciation, he deducts $9,000 upfront.

Although the 100% rate is phasing out, understanding current percentages and rules will help you plan asset purchases effectively. Working with a tax professional ensures compliance and maximizes tax benefits.
