A Fort Myers plumbing contractor with 4 service trucks faces vehicle tax decisions that materially affect annual tax. Pick the right depreciation method, the right vehicle weight class, and the right business-use tracking system, and the firm captures the full deduction. Pick wrong on any of these, and the firm leaves $4,000–$15,000/year in deductions on the table. This page covers the practical mechanics for a Lee County plumbing operation.
Federal law requires choosing one method per vehicle in year 1 of business use. The choice locks the vehicle in for life (cannot switch from actual back to mileage on the same vehicle).
Standard mileage: 70¢/mile in 2025 (2026 likely similar). Multiply business miles × rate. Simple recordkeeping. Best for high-mileage low-vehicle-cost vehicles.
Actual expense method: Track all vehicle expenses (fuel, oil, maintenance, repairs, insurance, registration, tires) and depreciation. Multiply by business-use percentage. Better for high-value vehicles, low-mileage usage, or expensive maintenance.
F-250 service truck, $58,000 purchase, 25,000 miles/year, 100% business use:
| Method | Year 1 Deduction | Year 2-5 Deduction |
|---|---|---|
| Standard mileage (25K × $0.70) | $17,500 | $17,500/year |
| Actual expense + § 179 ($30,500 cap) | $30,500 + $5K operating expenses = $35,500 | $3K-$5K/year remaining depreciation + operating |
| Actual + § 179 + 40% bonus on remainder | $30,500 + $11K + $5K = $46,500 | $3K-$5K/year |
Actual method delivers significantly higher year-1 deduction; standard mileage delivers steady annual deduction with simpler recordkeeping. For a heavy service truck the actual method usually wins.
Trucks over 14,000 GVW are exempt from § 280F luxury auto caps. A 1-ton dually with utility body or service body crossing this threshold gets full Section 179 + bonus deduction in year 1. For a $75,000 service truck purchased with full bonus year (when 100% applies), the entire $75,000 was deductible in year 1. With 40% bonus in 2026, year-1 deduction is § 179 limit + 40% × remainder.
Service trucks driven occasionally for personal use require allocation:
Most plumbing contractors keep service trucks 100% business use — the truck stays at the shop or with the lead plumber for the workday and isn't used personally. Document this with a written use policy.
For a 4-truck fleet, expense management:
Many Fort Myers plumbing contractors lease service trucks instead of buying. Tax treatment of leases:
Actual method usually wins for service trucks — heavy vehicles unlock Section 179 + bonus depreciation. Standard mileage is simpler for low-cost personal trucks used partly for business. Choose carefully — once chosen, you cannot switch from actual back to mileage on the same vehicle.
Possibly. Trucks over 14,000 GVW are exempt from § 280F luxury caps and can be fully Section 179'd up to the income limit. With 40% bonus depreciation in 2026, year-1 deduction can equal § 179 + bonus + first-year MACRS. For a $60K heavy service truck, year-1 deduction often approaches the full purchase price.
Yes. Sales tax paid on the purchase is part of the depreciable basis. For a $58K truck + 7% Lee County sales tax = $4,060, total basis is $62,060.
Yes. Operating lease payments are deductible as ordinary expense each month. Capital leases (lease-to-own) allow Section 179 and bonus depreciation. High-value leased vehicles may have an 'income inclusion amount' that reduces the deduction.
