How do I account for equipment depreciation in construction?
Equipment depreciation spreads the cost of trucks, excavators, trailers, and other assets over their useful life instead of deducting the full amount when purchased. This matches the expense to the years you actually use the equipment and gives a more accurate picture of profitability.
For tax purposes, most construction equipment uses MACRS (Modified Accelerated Cost Recovery System). The IRS assigns each asset a recovery period. Vehicles typically depreciate over 5 years while heavy equipment and machinery usually fall into 5 or 7 year categories depending on the type. Land improvements like paving depreciate over 15 years.
Section 179 lets you deduct the full cost of qualifying equipment in the year you buy it, up to annual limits. Bonus depreciation allows additional first-year deductions on top of regular depreciation. These options can significantly reduce your tax bill in years when you make large equipment purchases. Whether to use accelerated deductions or spread them out depends on your overall tax situation and expected income in future years.
In your accounting records, you’ll track three things for each asset. The original cost, accumulated depreciation, and net book value. Each month or year, you record a depreciation expense that increases accumulated depreciation and reduces the equipment’s book value on your balance sheet. Most accounting software handles this automatically once you set up the asset correctly.
For contractors, understanding equipment depreciation matters beyond basic bookkeeping. When you’re trying to figure out if a job actually made money, you need to account for the equipment costs involved. If your $80,000 excavator worked three months on a single project, some portion of that depreciation belongs to that job’s costs. Without allocating equipment to jobs, your job costing reports overstate profitability because they’re missing real costs.
Setting up fixed assets correctly from the start saves headaches later. Record the purchase date, cost basis, expected useful life, and depreciation method for each piece of equipment. Keep documentation for major purchases since you’ll need it if the IRS questions your deductions.
Most contractors don’t need to become depreciation experts. What matters is having your equipment tracked in your accounting system with the right method applied consistently. Professional bookkeeping services in American Fork familiar with construction can set this up and make sure depreciation flows into your financial statements correctly.
