What Is the Section 179 Tax Deduction and How Do You Claim It?

For many small businesses, equipment is essential to the operation. Investing in new equipment can make a big difference to your bottom line. Whether you’re upgrading machinery, purchasing new technology, or adding vehicles to your fleet, these investments help your business stay competitive or get an edge.

While new equipment may be a major cost, it also comes with a key residual benefit: A tax write-off. Section 179 of the IRS tax code is designed to help businesses manage their tax liability while incentivizing capital investment. Here’s what to know about it.

What Is Section 179?

It was once the case that when a business bought a piece of equipment, the IRS required it to depreciate the cost over several years. That means you’d only deduct a portion of the asset’s cost each year according to its useful life.

Section 179 flips the script. It allows businesses to expense the full purchase price of qualifying equipment and/or software purchased or financed during the tax year. Instead of waiting years to recoup the cost through depreciation, you can deduct the entire amount from your gross income in the year the asset is placed in service.

For many businesses, this can be a powerful cash flow tool. By lowering your taxable income for the current year, you effectively reduce the out-of-pocket cost of your new equipment. If you’d prefer to spread the depreciation over multiple years, you may still elect to do so.

Qualifying Property for Section 179

Not every business purchase qualifies for Section 179. Generally, the provision covers tangible personal property, which includes:

• Machinery and manufacturing equipment
• Office technology and computers
• Off-the-shelf software
• Office furniture
• Business vehicles (with specific weight and usage restrictions)
• Certain improvements to non-residential real property (e.g., HVAC, fire suppression, or security systems)

To qualify, the equipment must be used for business purposes more than 50% of the time. If your usage is mixed, your deduction must be prorated based on the percentage of business use.

Can You Use Section 179 for Financed Equipment?

The IRS allows you to take the full Section 179 deduction on equipment that is financed through a loan or a qualifying lease as long as the asset is placed into service by the end of the tax year. Because Section 179 is tied to ownership and placement in service rather than the full payment of the asset, you can get the equipment you need today, pay for it over time, and still claim the full tax deduction.

How to Claim Section 179

Candace Stevens is an Enrolled Agent and IRS resolution specialist with more than 30 years of experience. She provides this extensive overview of how Section 179 works for different types of business entities.

“Consider a business that purchases and places into service $100,000 of qualifying equipment during the year and elects to expense the entire cost under Section 179.

Sole Proprietorship (Schedule C)

For a sole proprietor, the deduction is claimed directly on Schedule C. However, the deduction is limited to the taxpayer’s net business income. If the business generates only $60,000 of profit before the Section 179 deduction, the taxpayer can deduct $60,000 in the current year. The remaining $40,000 is carried forward and may be deducted in a future year when sufficient business income exists.

Partnership

Partnerships claim the Section 179 deduction at the entity level, but the deduction passes through to the partners on their Schedule K-1s. Each partner must apply the Section 179 limitations on their individual return, including the taxable income limitation. For example, if two partners each own 50% of the business, each would receive a $50,000 Section 179 deduction. If one partner lacks sufficient taxable income to utilize the full deduction, the unused portion carries forward until it can be used.

S Corporation

S corporations also pass the Section 179 deduction through to shareholders on Schedule K-1. Assume an S corporation purchases $100,000 of equipment and has two equal shareholders. Each shareholder receives a $50,000 Section 179 deduction.

However, shareholders must have sufficient stock and debt basis to claim the deduction. If a shareholder’s basis is only $30,000, they may deduct $30,000 currently, while the remaining $20,000 is suspended and carried forward until an additional basis becomes available. This is an area where proactive tax planning can make a significant difference.

C Corporation

A C corporation claims the Section 179 deduction directly on its corporate tax return. The deduction reduces the corporation’s taxable income and does not pass through to shareholders. Like other entities, the Section 179 deduction generally cannot create or increase a net operating loss. Any amount that cannot be used because of the taxable income limitation is carried forward to future years.”

2026 Deduction Limits

Section 179 is designed to help small and medium-sized businesses, so it includes spending caps to prevent larger corporations from monopolizing the benefit. These limits are adjusted annually for inflation:

• 2026 Maximum Deduction: You can elect to expense up to $2,560,000 of qualifying purchases.
• Spending Cap: The deduction begins to phase out dollar-for-dollar once your total qualifying purchases for the year exceed $4,090,000.
• Full Phase-Out: The deduction is completely eliminated once your total purchases reach $6,650,000.

Limitations to Section 179

Section 179 can be a great tool for business owners, but there are important limitations to understand:

• Taxable Income Limit: Your Section 179 deduction cannot exceed your business’s total taxable income for the year. If you have a net loss, you generally cannot use Section 179 to create or increase a net operating loss (NOL), though you may be able to carry forward unused amounts.
• Placement in Service: Ordering equipment isn’t enough. The asset must be delivered, installed, and ready for use in your business by December 31 of the tax year you are claiming.
• Recapture Rules: If you sell the equipment or if your business usage drops to 50% or less in a future year, you may be required to “recapture” (repay) some of the tax benefits you previously claimed.

Utilizing Section 179

Section 179 is a highly effective tax strategy available to modern businesses. By aligning your equipment expenditures with your tax planning, you can balance strategic investments with a financial strategy that supports your growth.

As with any tax strategy, always work closely with your accountant or tax professional. They can help you determine the best approach for your specific situation—whether it’s leveraging Section 179, utilizing bonus depreciation, or a combination of both—to ensure you’re maximizing your annual tax strategy.
