How do I track equipment depreciation for my contracting business?
Equipment depreciation can feel complicated but the basics are straightforward. When you buy a piece of equipment for your contracting business, you don’t deduct the full cost in the year you buy it. Instead, you spread that cost over the useful life of the asset. This reflects how a truck or excavator provides value over many years rather than just the purchase year.
Start by creating a fixed asset schedule. This is a list of every piece of equipment your business owns along with the purchase date, original cost, useful life, and depreciation method. Include trucks, trailers, power tools over a certain dollar threshold, heavy equipment, and anything else expected to last more than a year.
Most contractors use MACRS for tax purposes because the IRS requires it. Under MACRS, different types of equipment have different recovery periods. Vehicles and light trucks are 5-year property. Heavy equipment and office furniture typically fall under 7-year property. The IRS publishes tables showing exactly how much you can depreciate each year.
Section 179 lets you deduct the full cost of equipment in the year you buy it instead of spreading it out. For construction businesses buying expensive equipment, this can be a significant tax benefit in high-income years. But it’s not always the right choice. If you expect your income to be higher in future years, spreading the deduction might save more overall. This is where working with an accountant helps.
In QuickBooks, set up fixed asset accounts in your chart of accounts. When you buy equipment, record it as an asset rather than an expense. Then set up a depreciation schedule and record monthly or annual depreciation entries. Many contractors handle this at year end with their accountant rather than tracking monthly.
Keep documentation on every piece of equipment. The purchase invoice, financing documents, and any improvements you make to the asset all matter. If you sell equipment or trade it in, you need the original cost basis to calculate gain or loss on the sale.
The real value of tracking depreciation properly shows up in three areas. Your tax return is accurate and captures all the deductions you’re entitled to. Your financial statements reflect the true value of your equipment rather than showing it at full cost forever. And you can see what your equipment actually costs you per year, which helps with job pricing and knowing when replacement makes financial sense.
For contractors with significant equipment investments, working with experienced Macomb, MI bookkeepers makes this easier. They’ll maintain your asset schedule, record depreciation entries, and coordinate with your tax preparer so everything lines up properly.
