        What Changed for 2026

        Section 179 & Bonus Depreciation — 2025 vs. 2026

        Provision 2025 2026
        Max Section 179 deduction $2,500,000 $2,560,000
        Phase-out threshold (spending cap) $4,000,000 $4,090,000
        Deduction fully phased out at $6,500,000 $6,650,000
        Bonus depreciation 100% 100% (now permanent)

        Bottom line: The 2025 tax law (One Big Beautiful Bill Act) made 100% bonus depreciation permanent for qualifying equipment placed in service after January 19, 2025, and raised the Section 179 limits, which now adjust annually for inflation. For most generator purchases, you can still write off the full cost in the first year.

        What is the Section 179 Deduction?

        In simple terms, Section 179 is a tax incentive designed to encourage small and medium-sized businesses to invest in themselves.

        Instead of depreciating the cost of an asset over many years, Section 179 allows you to treat the entire purchase price as an expense and deduct it from your gross income in the same year you buy it. This significantly lowers your taxable income, resulting in substantial cash savings that you can reinvest back into your business.

        It’s a direct, powerful, and immediate way for the government to help you pay for the new or used equipment you need to grow.


        How Section 179 Works: A Simple Example

        Let’s break down the core concept without using specific annual limits, which can change.

        1. You Need Equipment: Your business needs a new backup generator. You find the perfect model and purchase it.
        2. You Elect to Take the Deduction: When you file your taxes for the year, you elect to take the Section 179 deduction for the full cost of that generator.
        3. You Lower Your Taxes: The full cost of the generator is subtracted from your business’s profit, lowering your taxable income. A lower income means a lower tax bill, leaving more cash in your pocket.

        This immediate deduction is far more beneficial than slowly writing off a small fraction of the asset’s value each year for five or seven years.


        What Equipment Qualifies for Section 179?

        The list of qualifying property is broad, but it perfectly covers the needs of industrial and commercial businesses. To qualify, the equipment must be purchased (or financed) and placed into service during the tax year.

        Key Qualifying Equipment Includes:

        • Heavy Equipment: Bulldozers, forklifts, excavators, etc.
        • Power Generators: Standby, prime, and mobile generators (diesel and natural gas).
        • Business Vehicles: Heavy-duty trucks, vans, and other vehicles over 6,000 lbs. GVWR.
        • Manufacturing & Production Machinery.
        • Computers & “Off-the-Shelf” Software.
        • Office Furniture & Equipment.

        Critically, both new and used equipment qualify for the Section 179 deduction, giving you maximum flexibility.


        Section 179 vs. Bonus Depreciation

        You’ll often hear “Bonus Depreciation” mentioned alongside Section 179. While they both help you accelerate depreciation, they have a key difference:

        • Section 179 is a targeted deduction with an annual spending cap. If you spend over a certain amount on equipment in a year, the deduction starts to shrink.
        • Bonus Depreciation is for businesses of all sizes and has no spending cap. It allows you to deduct a percentage of the remaining cost after taking the Section 179 deduction.

        Businesses typically use Section 179 first, up to its limit, and then apply Bonus Depreciation to the remaining amount. Working together, they can often allow you to write off 100% of your equipment cost in the first year.


        Frequently Asked Questions (FAQs)

        • Can I use Section 179 on a financed or leased generator? Yes! This is one of the best parts. The deduction is available even if you finance the equipment. You can deduct the full price of the generator before you’ve even made all your payments, which can often make your tax savings greater than your first year’s payments.
        • Does used equipment qualify? Absolutely. As long as the equipment is “new to you,” it qualifies.
        • Does my business need to be profitable to use the deduction? Yes. The Section 179 deduction cannot be used to create a net loss for your business. You can only deduct up to the amount of your net taxable income.
