Mobile auto detailing is a high-margin business with exceptionally low material costs. Products and supplies run 5-12% of revenue, one of the lowest material percentages among trades. The reason is simple: detailing products are applied in small quantities per vehicle, and the primary input is skilled labor and time. A bottle of ceramic coating that costs $100 can coat 3-5 vehicles at $1,500 each ($4,500-$7,500 in revenue from $100 in product). This means most revenue flows directly to taxable profit, making deduction tracking important for every dollar. The vehicle, equipment, and marketing expenses are where the deductions live.

What does a mobile detailer’s full tax picture look like?

Hypothetical example

Round numbers. A solo mobile auto detailer offering full details and ceramic coatings. Year 2 (no major equipment purchases). Single filer.

Revenue: $125,000

Service	Revenue
Full details (300 vehicles x $300)	$90,000
Ceramic coatings (18 vehicles x $1,500)	$27,000
Add-ons (engine bay, headlight, interior-only)	$8,000
Total	$125,000

Deductions:

Category	Amount
Products and supplies (general)	$4,500
Ceramic coating product (18 x $150)	$2,700
Vehicle (16,000 miles x $0.70)	$11,200
Insurance (GL + garage keeper)	$3,000
Marketing (Google Ads + website + wraps)	$6,500
Phone, software, CRM	$1,800
Home office (simplified, 150 sqft)	$750
Polishing pad replacement	$300
Microfiber towel replacement	$500
Certification renewal	$200
Total	$31,450

Net profit: $125,000 - $31,450 = $93,550

Tax (sole proprietor):

SE tax: $93,550 x 92.35% x 15.3% = $13,213
SE deduction: ($6,607)
QBI: $93,550 x 20% = ($18,710)
Taxable: $93,550 - $6,607 - $18,710 - $15,000 = $53,233
Income tax: approximately $7,010
Total: $20,223 (16.2% of revenue)

Ceramic coating profitability breakdown:

	Full Detail	Ceramic Coating
Revenue per vehicle	$300	$1,500
Product cost	$15	$150
Time	3 hours	10 hours
Revenue per hour	$100	$150
Product margin	95%	90%

Both services are highly profitable, but ceramic coatings yield 50% more revenue per hour. The product cost is higher ($150 vs. $15), but the revenue is 5x higher. Every day shifted from full details to ceramic coatings increases daily revenue by approximately $600 ($1,500 for one coating vs. $900 for three details in the same time).

Year 1 startup deductions:

Item	Cost	Year 1 Deduction
Used van or SUV	$20,000	$20,000 (if over 6,000 lbs)
Pressure washer	$1,500	$1,500
DA polisher + rotary	$800	$800
Vacuum, steamer, foam cannon	$1,200	$1,200
Ceramic coating certification	$1,000	$1,000
Initial product inventory	$2,000	$2,000
Website + first 3 months marketing	$3,500	$3,500
Total	$30,000	$30,000

With $30,000 in Year 1 deductions and $80,000 in first-year revenue (ramping up), net profit is approximately $30,000. Total tax: approximately $6,000. The $20,000 vehicle depreciation alone saves approximately $6,600 in taxes.
