Mobile Auto Detailing Business: LLC vs. S-Corp Tax Structure

Mobile auto detailing entity structure:

SSTB classification: NOT an SSTB. Auto detailing is a physical cleaning and restoration service. Not consulting, health care, financial services, or other enumerated SSTB categories.

Revenue model:

• Basic wash and wax: $100-$200
• Interior detail: $150-$300
• Full detail (interior + exterior): $250-$500
• Paint correction (machine polishing): $300-$800
• Ceramic coating (consumer grade): $500-$1,500
• Ceramic coating (professional multi-layer): $1,000-$3,000
• Paint protection film (PPF): $1,500-$5,000+ (if offering)
• Solo operator: $80,000-$180,000/year
• Average ticket: $250-$400 for full details
• Repeat customers: 2-4x per year per customer (seasonal or quarterly)

Margins:

• Product costs: 5-12% of revenue (very low)
• Vehicle expenses: 8-12% of revenue
• Insurance: 2-4% of revenue
• Marketing: 5-10% of revenue (higher in growth phase)
• Net margin (solo): 65-80%

Ceramic coating premium:

• A ceramic coating job takes 8-16 hours (1-2 days of work)
• Revenue: $1,000-$3,000 per vehicle
• Product cost: $50-$200 (coating product itself)
• Margin: 90%+ on the coating product (labor is the main input)
• Certification from coating manufacturers (Gtechniq, CQuartz, IGL) opens access to professional-grade products and commands higher prices
• Training cost ($500-$2,000): deductible

S-Corp break-even: $55,000-$65,000 in net profit

• Full-time solo detailers typically reach this in Year 1 or early Year 2
• Equipment costs are moderate (no truck-mount system like carpet cleaning)
• The high margin means most revenue becomes taxable profit
• Payroll + return costs: $1,700-$3,500/year

Scaling:

• Adding a second detailer (employee or subcontractor): requires 1099 or W-2 payroll
• Fleet/dealership accounts: recurring revenue at lower per-vehicle prices but high volume
• Detailing studio (brick-and-mortar): higher overhead but enables PPF and indoor ceramic coating
