What is IRS Publication 946?
IRS Publication 946 provides clear instructions on how to depreciate property under U.S. tax law. It explains the various types of property that can be depreciated, how to determine depreciation amounts, and the methods that should be used for different types of property. Depreciation allows businesses to deduct the cost of their assets over time, rather than in one lump sum, which can significantly reduce taxable income in the short term. IRS Publication 946 also includes information on the Modified Accelerated Cost Recovery System (MACRS), which is the primary system used for most types of property.
This publication is especially helpful for individuals and businesses that own tangible property, such as equipment, buildings, or vehicles, that is expected to last for more than one year. By providing tax deductions for the depreciation of these assets, IRS Publication 946 helps lower the taxable income and allows businesses to reinvest that money into their operations.
Key Topics in IRS Publication 946
Section 179 Deduction
The Section 179 deduction is one of the most beneficial aspects of IRS Publication 946 for businesses. It allows businesses to deduct the full cost of qualifying property in the year it is purchased and put into use, rather than spreading that deduction over several years. This is especially helpful for small businesses that need immediate tax relief. However, there are limits on the total amount that can be deducted each year, so it’s important to consult the publication to understand how to claim this deduction correctly.
Special Depreciation Allowance
The special depreciation allowance, also known as bonus depreciation, allows businesses to deduct a significant percentage of the cost of qualified property in the year it is placed in service. This deduction is especially helpful for businesses purchasing new or used property. IRS Publication 946 outlines the specific property that qualifies for this special allowance and provides guidance on how to calculate the deduction.

MACRS (Modified Accelerated Cost Recovery System)
MACRS is the primary system used by businesses for depreciating property under U.S. tax law. It allows for the deduction of property depreciation over a set number of years, with specific schedules depending on the type of property. IRS Publication 946 provides detailed information on how to use MACRS, the recovery periods for different types of property, and the methods that can be used to calculate depreciation. Understanding MACRS is crucial for anyone filing tax returns for businesses with depreciable assets.
Listed Property
IRS Publication 946 also covers listed property, which refers to property that can be used for both business and personal purposes, such as cars and computers. Special rules apply to the depreciation of listed property, including restrictions on how much depreciation can be claimed. It’s important to follow these rules to avoid errors when filing taxes and ensure compliance with IRS guidelines.

By understanding the depreciation methods outlined in the publication, businesses can make strategic decisions about how and when to depreciate their property.
