Section 179: What This Equipment Tax Deduction Means For 2025

Did you buy equipment and put it to use in the 2025 calendar year? Read on to learn how you can use the section 179 tax deduction to save money on your 2025 taxes. We’ll also explain the difference between section 179 and bonus depreciation.

 

 

What Is The Section 179 Tax Deduction?

Section 179 Definition

Section 179 is an expense deduction and part of the Internal Revenue Code (IRC). It allows businesses to deduct the full purchase price of qualifying depreciable assets purchased or financed during the 2025 tax year.

 

The maximum deduction for 2025 is $2,500,000. Depending on your 2025 purchases and ability to use the deduction, your business could receive sizable benefits.

 

What Section 179 Is For

The U.S. Internal Revenue Service created Section 179 to help small businesses invest more money in their companies. The deduction is designed to help offset the costs of maintaining and expanding businesses through equipment purchases, upgrades, and more.

 

According to the IRS, a wide range of equipment and other assets can qualify, such as certain types of heavy machinery, vehicles, office equipment, and software. Keep reading to learn exactly what assets qualify.

 

How Section 179 Works

Before section 179 was created, if a business spent $50,000 on a machine, it could write off only $10,000 a year for five years through depreciation. To benefit financially, a business would have to write off the same equipment over multiple tax years. This took too much time and caused a lot of headaches.

 

With Section 179, a business can write off the entire purchase price of qualifying equipment immediately for the current tax year. This simpler approach saves time when filing taxes.

 

 

Can My Business Use Section 179?

What Businesses Can Benefit?

The tax deduction covers a broad range of equipment and business goods, so many different types of businesses can benefit from using it. Whether you’re a construction company owner, contractor, farmer, rancher, owner/operator in the commercial transportation industry, or other small or medium-sized business owner, you can consider using the section 179 deduction on qualifying purchases.

 

What Equipment & Purchases Qualify?

New and used equipment that is purchased or financed and put into use in the 2025 tax year currently qualifies for the section 179 deduction.

 

Whether you purchased, financed, or leased qualifying assets throughout the year, you can take advantage of the section 179 deduction. Even if you purchased equipment during end-of-year auctions, as long as you put those assets into service before December 31, 2025, they will qualify for the deduction.

 

Qualifying assets may include the following items:

• Construction equipment
• Trucks and trailers
• Delivery vans
• Commercial vehicles
• Sport utility vehicles
• Computers
• Software
• Appliances
• Office equipment
• Office furniture
• Farm Machinery
• Livestock

 

 

What Are The 2025 Dollar Limits Of Section 179?

Here are the maximum limits for taking advantage of the section 179 tax code in 2025:

• Maximum write-off: $2,500,000
• Maximum total purchased: $4,000,000

 

The maximum section 179 expense deduction for the 2025 tax year is $2,500,000 (up from $1,220,000 for the 2024 tax year). This limit is reduced by the amount by which the cost of section 179 property placed in service during the tax year exceeds $4,000,000 (by contrast, the limit was $3,050,000 for the 2024 tax year).

 

The IRS also specifies that the maximum section 179 expense deduction for sport utility vehicles placed into service in tax years beginning in 2025 is $31,300 (up from $30,500 for the 2024 tax year).

 

How Is Bonus Depreciation Different From Section 179?

Bonus depreciation is commonly known as the “additional first-year depreciation deduction.” It is section 168(k) of the IRC.

 

Bonus depreciation is a tax incentive that allows businesses to deduct a larger portion of the cost of qualifying business assets (including new and used equipment) in the year of purchase instead of spreading out the deduction over several years. This may sound a lot like section 179, but the two are different; both can, in some cases, be used in the same tax year.

 

Many businesses using the section 179 tax deduction opt to use bonus depreciation after reaching the section 179 spending limit. For the 2025 tax year, the bonus depreciation rate is 100% of the cost of qualifying assets purchased and put into service in the 2025 calendar year.
