The return of 100% bonus depreciation for assets placed in service after January 19, 2025, is a big deal—especially for business owners facing expenses such as aging fleets, rising repair costs, and tightening margins. 

The 100% bonus depreciation rule is especially powerful for asset‑heavy, closely held businesses that regularly invest in equipment, vehicles, and technology. In practical terms, it means you can immediately expense the full cost of qualifying equipment in the year it’s placed in service, rather than depreciating it over time. That sounds like an obvious win, but, like most things in tax planning, the benefit depends heavily on timing, structure, and your broader financial picture. 

Where 100% Bonus Depreciation Works

For many of our clients who rely on significant equipment, machinery, and vehicle investments, this provision is acting as a catalyst not only to save money but also to modernize operations. 

First, it can be used to accelerate tax savings when income is high. If your business is coming off a strong year—or you expect one in 2026—100% expensing can significantly reduce taxable income. It can be especially valuable for pass-through entities in which income flows to owners who are taxed at higher individual rates.

It can also help improve cash flow in capital-intensive businesses. For example, contractors often face high upfront costs for equipment such as excavators, trucks, and cranes. Being able to deduct 100% of those costs immediately can offset the cash outlay and improve after-tax liquidity.

It can simplify the buy-versus-lease decision. Leasing has traditionally appealed to businesses trying to manage cash flow while avoiding large capital expenditures. With 100% bonus depreciation back on the table, buying can be more attractive. (Note: Certain financing leases—another form of buying in which the lessee has all of the burden/benefits of ownership—may also qualify.)

And it can help you leverage financing more strategically. Many businesses are pairing bonus depreciation with equipment financing. The tax deduction is based on the full purchase price, even if the asset is financed. This creates a timing advantage: Deduct now, pay over time.

Finally, it provides a competitive advantage. These factors can amplify the competitive advantage of being able to afford newer equipment or technology that offers better uptime, efficiency, and safety. When tax policy aligns with operational upgrades, it’s a rare win-win.

Where It Can Backfire

Despite the upside, we’ve also seen businesses treat 100% bonus depreciation as a green light to overspend or misalign their tax strategy. Don’t fall for buying equipment you don’t need or pushing your business into a tax loss for the year that can’t be utilized correctly. For instance, limitations on excess business losses can defer benefits. And carrying 100% expensing into a lower-income year can be ineffective. In those cases, spreading depreciation over time or electing out of the bonus might produce a better long-term outcome.

Then there’s Section 179 expensing. The two tax strategies often get lumped together, but they can be very different. Section 179 has income limitations and phaseouts, while 100% bonus depreciation does not. Strategically coordinating the two—rather than always defaulting to bonus depreciation—could yield better results.

Also, consider resale. When you fully expense an asset and later sell it, more of the proceeds may be taxed as ordinary income due to depreciation recapture. This is particularly relevant for contractors who frequently turn over equipment.

Considerations for 2026

The businesses getting the most out of 100% bonus depreciation aren’t just reacting; they’re proactively planning around it. It’s important to forecast income before making large purchases and consider partial elections when they make sense. You don’t have to apply bonus depreciation to every purchase.

Then, think about your timing. Take financing and cash flow into consideration. Just because you can deduct it doesn’t mean you should strain liquidity. It’s important to carefully time the “placed in service” date, too. The deduction applies when the asset is placed in service—not when it’s ordered or paid for. Delays in delivery or readiness can push deductions into a different tax year. We’ve seen this happen with businesses that purchase before the end of the year but then invest in upgrades or customizations that delay use. 

And, finally, don’t ignore exit planning. If you’re within a few years of selling your business, aggressive expensing can affect valuation, normalized earnings, and deal structure.

There are few more powerful tax tools than 100% bonus depreciation for closely held businesses, especially in construction and other asset-heavy industries. But it’s not a blanket strategy. Used well, it can improve cash flow, support growth, and reduce tax burden. Used poorly, it can create mismatches, unnecessary debt, and future tax friction. The difference comes down to alignment: Your tax strategy should follow your business strategy, not the other way around.
