Home inspection is a low-overhead, high-margin business. Startup costs are minimal ($5,000-$15,000 for training, licensing, tools, and marketing), and ongoing expenses are dominated by vehicle costs, insurance, and marketing. The typical home inspection runs $300-$600, takes 2-4 hours including the report, and the only material cost is the inspector’s time and fuel to get there. Gross margins of 70-80% are common for solo inspectors. The critical tax classification: home inspection is NOT a specified service trade or business (SSTB) under IRC 199A. While it involves professional judgment, it’s an evaluation of physical property conditions, not a consulting, financial, or health service. The full QBI deduction applies at all income levels.

✓Key takeaway

Entity structure comparison for home inspectors:

Sole proprietorship (default):

Simple, low cost
No separate return needed
E&O insurance is the primary liability protection
Best for: part-time inspectors, net profit under $55,000

Single-member LLC:

Adds liability protection beyond E&O insurance
Same tax treatment as sole prop
Looks more professional to real estate agents and clients
Best for: full-time inspectors at any income level

S-Corp (LLC with S election):

SE tax savings on distributions
Requires W-2 salary to owner
Additional compliance cost ($1,500-$2,500/year)
Best for: net profit above $55,000-$65,000

S-Corp break-even calculation:

Net profit: $80,000
Sole prop SE tax: $80,000 x 92.35% x 15.3% = $11,300
S-Corp (salary $40,000): FICA = $6,120
SE tax savings: $5,180
S-Corp compliance: $2,000
Net savings: $3,180/year

At $55,000 net profit, savings are approximately $1,500 after compliance costs. Below $55,000, the S-Corp isn’t cost-effective.

Typical home inspector financials (solo, full-time):

Inspections/year: 250-400
Average fee: $400
Annual revenue: $100,000-$160,000
Vehicle (standard mileage, 20,000 miles x $0.70): ($14,000)
E&O insurance: ($2,000-$4,000)
General liability insurance: ($1,000-$2,000)
Report software (Spectora, HomeGauge): ($1,200-$2,400)
Marketing (website, referral programs): ($3,000-$6,000)
Tools and equipment replacement: ($1,000-$3,000)
Phone and internet: ($1,200-$2,400)
Licensing and CE: ($500-$1,000)
Net profit: $70,000-$130,000
Net margin: 70-80%

What does a home inspector’s tax picture look like?

Hypothetical example

Round numbers. A full-time home inspector, sole proprietor, single filer. 300 inspections at $425 average.

Revenue: $127,500

Expenses:

Vehicle (25,000 business miles x $0.70): $17,500
E&O insurance: $3,000
General liability: $1,500
Report software (Spectora): $1,800
Marketing and website: $4,000
Tools (thermal camera, moisture meter, electrical tester replacements): $2,000
Phone: $1,200
Licensing and CE: $800
Office supplies and report printing: $500
Total expenses: $32,300

Net profit: $95,200

Sole proprietor tax:

SE tax: $95,200 x 92.35% x 15.3% = $13,443
SE deduction: $6,722
Taxable income: $95,200 - $6,722 - $15,700 = $72,778
Income tax: approximately $10,900
QBI deduction (20% x $95,200 = $19,040): saves approximately $4,189
Adjusted income tax: approximately $6,711
Total tax: $13,443 + $6,711 = $20,154
Effective rate: 21.2%

S-Corp (salary $45,000):

FICA on salary: $6,885 (employer + employee)
Income tax on $95,200 total: approximately $10,900
QBI deduction: saves approximately $4,189
Total tax: approximately $13,596
S-Corp savings: $6,558/year
After compliance cost ($2,000): net savings $4,558/year

Adding ancillary services (increasing revenue without proportional cost increase): Many home inspectors add:

Radon testing ($150/test, 100 tests = $15,000, equipment cost $1,000)
Termite/WDI inspection ($75-$150, subcontracted or licensed)
Sewer scope ($150-$250, camera cost $3,000-$8,000)
Mold testing ($100-$300, lab fees $30-$50/sample)

These add-ons increase revenue $15,000-$40,000 with minimal additional time. Each additional dollar has a 70-80% margin because the inspector is already at the property.
