MACRS Depreciation Overview

By Admin Mar 25, 2024 #MACRS

When it comes to managing finances for a business, one important aspect to consider is depreciation. Depreciation is the process of allocating the cost of an asset over its useful life. This allows businesses to deduct the cost of the asset from their taxable income each year, reducing their tax liability. One method of calculating depreciation is through the Modified Accelerated Cost Recovery System (MACRS). In this blog post, we will delve into the details of MACRS and its schedule table, discussing its classifications, deductions, calculations, and impact on business decision-making.

Property Classifications Under MACRS

Before we dive into the specifics of MACRS, it is important to understand the different property classifications that fall under this system. MACRS applies to tangible property used in a trade or business, such as buildings, machinery, equipment, and furniture. These properties are classified into different categories based on their useful life, with each category having a specific depreciation method and recovery period.

The first category is called “3-year property” and includes assets with a useful life of three years or less, such as tractors, racehorses, and certain types of livestock. The second category is “5-year property,” which includes most office equipment, computers, and vehicles. The third category is “7-year property,” which includes assets like office furniture, appliances, and certain types of agricultural equipment. The fourth category is “10-year property,” which includes assets like water utility property, municipal waste treatment plants, and certain types of trees and vines. Finally, the fifth category is “15-year property,” which includes assets like roads, fences, and certain types of land improvements.

MACRS Depreciation Deductions

Under MACRS, businesses can claim depreciation deductions for each property classification based on its recovery period. The recovery period is the estimated useful life of the asset, which is determined by the IRS. For example, a 5-year property will have a recovery period of five years, and a business can claim depreciation deductions for that asset over those five years.

The amount of depreciation deduction that a business can claim each year depends on the depreciation method used. There are two methods of depreciation under MACRS: the General Depreciation System (GDS) and the Alternative Depreciation System (ADS). The GDS method is the most commonly used and allows businesses to deduct a larger portion of the asset’s cost in the earlier years of its useful life. On the other hand, the ADS method allows for a slower depreciation rate, resulting in smaller deductions each year but a longer recovery period.

Modified Accelerated Cost Recovery System (MACRS) Table

To determine the depreciation deductions for each property classification, businesses can refer to the MACRS schedule table provided by the IRS. This table lists the applicable recovery periods and depreciation rates for each category of property. Let’s take a closer look at the MACRS table for 5-year property as an example:

YearDepreciation Rate

As you can see, the depreciation rate decreases each year, with a higher percentage being deducted in the earlier years. This is known as the “double declining balance” method, which allows businesses to deduct a larger portion of the asset’s cost in the first few years of its useful life.

Exceptions to the MACRS Depreciation Table

While the MACRS schedule table provides a general guideline for calculating depreciation deductions, there are some exceptions to consider. For example, if an asset is used for both personal and business purposes, the depreciation deduction must be prorated based on the percentage of business use. Additionally, if an asset is placed in service mid-year, the depreciation deduction for that year will be prorated based on the number of months it was in use.

Another exception to the MACRS table is the “mid-quarter convention.” This applies when more than 40% of a business’s total assets are placed in service during the last quarter of the tax year. In this case, the business must use a different depreciation method, which results in a slower rate of depreciation.

Advantages and Disadvantages of Using MACRS

One of the main advantages of using MACRS is its simplicity. The schedule table provides a straightforward method for calculating depreciation deductions, making it easier for businesses to manage their finances. Additionally, the double declining balance method allows for larger deductions in the earlier years, which can help businesses reduce their tax liability.

However, there are also some disadvantages to consider. One major disadvantage is that the MACRS system does not take into account the actual useful life of the asset. This means that some assets may be depreciated faster than they actually wear out, resulting in a lower tax basis for those assets. Additionally, the depreciation deductions may not accurately reflect the true value of the asset over time.

Depreciation Calculations Under MACRS

To better understand how MACRS works, let’s look at an example. Say a business purchases a piece of equipment for $50,000 with a useful life of five years. According to the MACRS table for 5-year property, the depreciation rate for the first year would be 20%. This means that the business can deduct $10,000 from their taxable income in the first year. In the second year, the depreciation rate would be 32%, resulting in a deduction of $16,000. This pattern continues until the end of the asset’s useful life.

It is important to note that businesses must use the same depreciation method for all assets within the same property classification. For example, if a business chooses to use the GDS method for one 5-year property, they must use it for all 5-year properties.

Impact of MACRS on Business Decision-Making

The MACRS system can have a significant impact on business decision-making, particularly when it comes to purchasing new assets. Since the depreciation deductions are based on the recovery period, businesses may be more inclined to purchase assets with shorter recovery periods to take advantage of larger deductions in the earlier years. This can lead to businesses making decisions based on tax benefits rather than the actual needs of the company.

Additionally, the depreciation deductions under MACRS can affect a business’s cash flow. In the earlier years, when the deductions are higher, the business may have a lower taxable income and therefore pay less in taxes. However, in the later years, when the deductions are smaller, the business may have a higher taxable income and pay more in taxes. This can create fluctuations in cash flow that businesses need to consider when making financial decisions.

Recent Changes to the MACRS Depreciation Table

In recent years, there have been some changes to the MACRS depreciation table. In 2017, the Tax Cuts and Jobs Act (TCJA) was passed, which made significant changes to the tax code. One of these changes was to the depreciation rules for certain types of property.

Under the TCJA, businesses can now deduct the full cost of qualified property in the year it is placed in service, rather than spreading out the deductions over several years. This is known as “bonus depreciation” and applies to certain types of property, such as equipment, machinery, and furniture. This change has allowed businesses to take advantage of larger deductions in the first year, providing a boost to their cash flow.

Alternative Depreciation Methods to MACRS

While MACRS is the most commonly used method for calculating depreciation, there are also alternative methods available. These methods may be more suitable for certain types of assets or businesses, depending on their specific needs and circumstances.

One alternative method is the Straight Line Depreciation (SLD) method, which allows for an equal amount of depreciation to be deducted each year over the asset’s useful life. This method may be more appropriate for assets that have a longer useful life or for businesses that prefer a more consistent approach to depreciation.

Another alternative method is the Sum-of-the-Years’ Digits (SYD) method, which allows for a higher depreciation deduction in the earlier years and a lower deduction in the later years. This method may be more suitable for assets that have a higher value in the earlier years, such as vehicles or equipment.


In conclusion, MACRS is a widely used method for calculating depreciation deductions for business assets. Its schedule table provides a simple and straightforward way to determine the deductions for each property classification. However, it is important for businesses to understand the different classifications, exceptions, and alternative methods available to make informed decisions about their finances. With recent changes to the tax code and the availability of alternative methods, businesses should carefully consider which depreciation method best suits their needs.
