How does accelerated depreciation work?

Writer: Todd PhillipsTodd Phillips

Growing Businesses rely on accelerated depreciation to fund growth.  Here’s how:

Depreciation is a tax deduction that allows businesses to recover the cost of assets over time. Accelerated depreciation is a powerful tool that speeds up this process, enabling businesses to take larger deductions earlier in an asset’s life. By front-loading deductions, businesses can reduce taxable income and improve cash flow, which can be reinvested for growth. However, accelerated depreciation also comes with trade-offs, such as the potential for recapture taxes if the asset is sold.

Understanding how accelerated depreciation works—and its main methods, including MACRS, bonus depreciation, and Section 179—can help businesses make strategic decisions to optimize their tax outcomes.


What is Accelerated Depreciation?

Accelerated depreciation is a method of allocating an asset’s cost to earlier years of its useful life, resulting in larger deductions during those initial years. This contrasts with straight-line depreciation, where the deduction is evenly distributed over the asset's life.

The main advantage of accelerated depreciation is the boost it gives to a business’s cash flow early on, making funds available for reinvestment. While it does not change the total amount of depreciation over the asset's life, the timing of the deductions provides economic benefits by taking advantage of the time value of money.


Key Methods of Accelerated Depreciation

1. MACRS (Modified Accelerated Cost Recovery System)

The Modified Accelerated Cost Recovery System (MACRS) is the standard method for depreciating most business assets in the United States. It provides a way to recover an asset's cost faster than the straight-line method, where deductions are spread evenly over the asset's useful life.

Comparison: Accelerated vs. Straight-Line Depreciation

  • Accelerated Depreciation (e.g., MACRS):

    • Provides larger deductions in the earlier years of an asset’s life.

    • Takes advantage of the time value of money by allowing businesses to defer taxes and reinvest the savings sooner.

    • Reduces taxable income more significantly in the short term, which can improve cash flow.

  • Straight-Line Depreciation:

    • Spreads the asset’s cost evenly over its useful life.

    • Deductions are consistent year-to-year, providing predictability but no upfront tax advantage.

    • May not align as well with the declining value or utility of many assets over time.

How MACRS Works

Under MACRS, assets are classified into specific recovery periods (e.g., 3, 5, 7, or 39 years) that determine how quickly they can be depreciated. MACRS uses one of two accelerated methods for calculating deductions:

  • 200% declining balance method: Doubles the straight-line rate, resulting in larger deductions in the earlier years.

  • 150% declining balance method: A slower acceleration, used for specific types of property, such as agricultural equipment.

For most assets, MACRS automatically switches to straight-line depreciation partway through the schedule to ensure full recovery of the asset’s cost by the end of its recovery period.


2. Bonus Depreciation

Bonus depreciation allows businesses to deduct a large percentage of an asset's cost in the first year it is placed in service, providing an immediate tax benefit.

  • Eligibility: Applies to new and used tangible personal property with a useful life of 20 years or less. Examples include machinery, equipment, and certain leasehold improvements.

  • Recent changes: The Tax Cuts and Jobs Act (TCJA) temporarily allowed 100% bonus depreciation for assets placed in service between 2018 and 2022. This percentage began phasing down after 2022 (e.g., 80% in 2023, 60% in 2024).

  • Benefits:

    • Significant upfront tax savings that improve cash flow.

    • Flexibility: Bonus depreciation applies automatically unless a taxpayer opts out.

  • Considerations:

    • The temporary nature of bonus depreciation means businesses should plan acquisitions strategically to maximize this benefit.

    • Assets must meet eligibility criteria, so understanding what qualifies is critical.


3. Section 179 Expensing

Section 179 allows businesses to deduct the full cost of certain qualifying assets in the year they are placed in service, up to an annual limit.

  • Key features:

    • The maximum deduction for 2023 is $1,160,000, with a phase-out threshold starting at $2,890,000 of total equipment purchases.

    • Eligible property includes machinery, equipment, off-the-shelf software, and certain building improvements (e.g., HVAC systems, roofs).

  • Differences from bonus depreciation:

    • Section 179 has annual dollar limits, while bonus depreciation does not.

    • Taxpayers must actively elect to use Section 179, whereas bonus depreciation is automatic.

  • Why choose Section 179? It gives taxpayers more control, as they can select specific assets to expense, which can be useful when managing taxable income strategically


Economic Effects of Accelerated Depreciation

Time Value of Money

One of the primary benefits of accelerated depreciation is its ability to enhance cash flow by reducing taxable income in the early years of an asset’s life. By front-loading tax deductions, businesses can realize immediate tax savings that can be reinvested to generate additional returns. This makes accelerated depreciation a valuable tool for companies focused on growth.

To understand the impact, consider the time value of money: a dollar saved today is worth more than a dollar saved in the future because it can be invested or used to pay down debt.

Example: A business that saves $10,000 in taxes this year by using accelerated depreciation can reinvest that money into the business at a 5% annual return. Over five years, that initial $10,000 grows to $12,763. By contrast, if the business used straight-line depreciation and saved the same $10,000 incrementally over five years, the total benefit would be significantly less.

 

Impact of Recapture

Accelerated depreciation does come with potential downsides, such as depreciation recapture if the asset is sold. Recapture occurs when the IRS requires you to "pay back" a portion of the tax savings by taxing the prior deductions as ordinary income, up to the amount of gain.

  • Ordinary Income Rates: For most assets, recaptured depreciation is taxed at ordinary income rates, which may be higher than capital gains rates.

  • Lower Recapture Rates for Real Property: For real estate with straight-line depreciation, recaptured deductions are taxed at a maximum rate of 25%, which is often lower than the ordinary income rate.

Even with recapture, accelerated depreciation can still provide a net benefit. The initial savings are realized at a higher marginal tax rate (when the business may be more profitable), while recapture occurs later, often when the business or its owners may be in a lower tax bracket. Additionally, the time value of money ensures that the initial savings outweigh the future tax liability.

 

Practical Considerations and Strategies

Choosing the right depreciation strategy depends on the business’s financial and tax planning goals.

  1. Immediate Cash Needs vs. Long-Term Savings:

    • If immediate cash flow is critical, accelerated depreciation provides significant upfront savings.

    • For businesses prioritizing even deductions over time, straight-line depreciation may be preferable.

  2. Combining Strategies:

    • Start with Section 179 to fully expense smaller assets, up to the annual limit.

    • Use bonus depreciation for larger, qualifying purchases to maximize first-year deductions.

    • Apply MACRS for any remaining cost, ensuring consistent deductions in future years.

  3. Planning for Recapture:

    • Use deferral strategies like 1031 exchanges to roll gains into new assets, avoiding immediate recapture.

    • Consider reinvesting in similar assets to maintain deductions and cash flow.

 

Examples

Example 1: Bonus Depreciation for a Vehicle Purchase

A business purchases a $50,000 vehicle eligible for 100% bonus depreciation. In the first year, the company deducts the full $50,000 from its taxable income, reducing taxes by $12,000 (assuming a 24% tax rate). This upfront savings can be used to cover expenses or reinvest in the business. If the vehicle is sold in a few years, recapture may apply, but the initial cash flow boost often outweighs the later liability.

Example 2: Section 179 Expensing for Equipment

A business purchases a $200,000 piece of equipment. By electing Section 179, the company deducts the full cost in the first year, saving $48,000 in taxes (at a 24% tax rate). If the company’s total equipment purchases exceed the Section 179 cap, the excess can be depreciated using bonus depreciation or MACRS, maximizing the overall tax benefit. The immediate savings allow the business to invest in operations, providing growth opportunities.
