How do I handle equipment depreciation for my construction business?

When you buy a piece of equipment for your construction business, you generally can’t deduct the full cost as a business expense in the year you purchased it. Instead, you spread that cost over the useful life of the asset through depreciation. But there are several ways to accelerate those deductions, and construction businesses have some favorable options available.

Any equipment with a useful life of more than one year qualifies for depreciation. For construction, this includes excavators, backhoes, skid steers, concrete mixers, trucks, trailers, and similar heavy equipment. Smaller tools and supplies that cost $2,500 or less per item can be expensed immediately under the IRS de minimis safe harbor election. You don’t need to depreciate a $200 drill or a $500 saw.

The most popular option for small construction businesses is the Section 179 deduction, which lets you deduct the full purchase price of qualifying equipment in the year you buy it. The annual limit for 2024 is $1,250,000, which covers most small business equipment purchases. It applies to both new and used equipment as long as it’s new to your business. The one limitation is that your Section 179 deduction can’t exceed your business income for the year, so it won’t create a tax loss on its own.

Bonus depreciation is another option. For 2024, you can deduct 60% of the cost in the first year, with the percentage continuing to phase down by 20% annually. Unlike Section 179, bonus depreciation can create a loss, which makes it useful when you’re purchasing expensive heavy equipment and want to offset income from other sources.

If you don’t elect Section 179 or bonus depreciation, the default method is MACRS, which stands for Modified Accelerated Cost Recovery System. Construction equipment typically falls under a 5-year or 7-year recovery period depending on the asset type. Vehicles have their own rules and limitations on how much you can depreciate each year. MACRS spreads the deduction across several years, which sometimes makes sense if you expect higher income in future years and want to save the deductions for when they’ll offset more taxes.

Choosing the right method depends entirely on your tax situation. Taking the full deduction now feels good, but if you had a low-income year and expect higher earnings ahead, spreading depreciation out might save you more in the long run. This is one of those decisions where the numbers matter more than the gut feeling, and a CPA can model out the scenarios for your specific situation.

On the bookkeeping side, maintain an equipment register that tracks each asset along with its purchase date, cost, depreciation method, and accumulated depreciation to date. When you eventually sell or dispose of a piece of equipment, you’ll need all of that information to calculate the gain or loss on the sale. Your Tampa Bay bookkeeping team should be updating this register every time you acquire or get rid of equipment so your financial statements reflect accurate asset values.

The biggest mistake we see is construction business owners who buy equipment and never properly record it as a fixed asset. They either expense it all immediately without making the proper tax election, or they simply forget to track it altogether. Both create problems at tax time and make your balance sheet unreliable. Set up the tracking from the start and update it consistently, and depreciation becomes straightforward instead of a year-end scramble.
