Power Washing Tax Deductions: Equipment, Chemicals, and Vehicle Expenses

Power washing deduction categories:

Chemicals and cleaning products (3-8% of revenue):

• Sodium hypochlorite (bleach, for soft washing): $0.50-$1.50/gallon, use 5-20 gallons/day
• Surfactant: $20-$50/gallon (diluted heavily, lasts weeks)
• Degreaser (for concrete, commercial): $15-$40/gallon
• Rust remover (oxalic acid): $20-$50/gallon
• Wood brightener: $15-$30/gallon
• Sealer/stain (if offering deck staining): $30-$80/gallon
• Annual chemical cost (solo operator): $3,000-$8,000
• All deductible as supplies or cost of goods sold

Equipment (moderate, one-time):

• Hot water pressure washer: $3,000-$8,000
• Cold water pressure washer: $1,500-$4,000
• Soft wash pump and system: $2,000-$5,000
• Surface cleaner (flat surface attachment): $200-$600
• Hose reels and hose (200-300 ft): $500-$1,500
• Spray tips and guns: $100-$300
• Water tank (100-500 gallon): $200-$1,500
• Chemical tank and injection system: $200-$500
• Generator (if needed for remote locations): $500-$2,000
• Ladder and safety harness: $200-$500
• All Section 179 or bonus depreciation eligible
• Most items under $2,500: de minimis safe harbor (expense immediately)

Trailer vs. truck-mounted (vehicle deduction implications):

• Trailer-mounted rig ($3,000-$10,000): the trailer is separate from the truck
  • The truck can use standard mileage rate (70 cents/mile for 2025)
  • The trailer is depreciated separately (5-year MACRS)
  • This is often the BETTER tax structure: standard mileage is simpler and often higher than actual expenses for newer trucks
• Truck-mounted rig: the pressure washer is permanently installed in the truck bed
  • The truck IS the business equipment
  • Must use actual expense method (can’t use standard mileage on a vehicle claiming depreciation)
  • Fuel, insurance, maintenance, depreciation all deducted as actual expenses
  • May be advantageous for older trucks with low payments and high mileage

Vehicle expenses:

• Standard mileage (if trailer setup): 70 cents/mile x 15,000-25,000 miles = $10,500-$17,500
• Actual method (truck-mounted): fuel + insurance + maintenance + depreciation
• Truck fuel: $5,000-$8,000/year
• Equipment fuel (gas-powered washer): $1,000-$2,000/year

Insurance:

• General liability: $800-$2,000/year
• Commercial auto: $1,500-$3,500/year
• Inland marine (equipment): $200-$600/year
• Workers’ comp (if employees): varies
• Pollution liability (for chemical runoff): $300-$800/year (recommended, increasingly required)
• Total: $3,000-$7,000/year

Marketing (higher than average for trades):

• Google Ads: $500-$2,000/month (power washing is competitive)
• Yard signs: $200-$500/year
• Door hangers: $300-$800/season
• Vehicle wrap: $2,000-$5,000 (one-time, depreciable)
• Before/after photos (your own work): free but highly effective
• Website and SEO: $100-$300/month
• Total marketing: $3,000-$12,000/year
