Home inspection is a business that scales well for solo operators: low overhead, no employees needed, high per-inspection revenue ($300-$600 per inspection), and minimal inventory. The primary expenses are vehicle costs, E&O insurance, and continuing education. Most home inspectors operate as sole proprietors, but the S-Corp election becomes beneficial once annual net profit exceeds $50,000-$60,000.

✓Key takeaway

Home inspection business tax profile:

NOT an SSTB. Home inspection is a technical trade, not consulting, engineering, or any enumerated SSTB. The inspector physically examines the property and reports factual findings. This preserves the full 20% QBI deduction at any income level. (Contrast with engineering, which is an enumerated SSTB under IRC 199A.)
High margins for solo operators. A solo home inspector doing 4-5 inspections per week at $400 average generates $83,200-$104,000 in gross revenue. After vehicle, insurance, and operating expenses of $15,000-$25,000, net profit is $60,000-$80,000, well into S-Corp territory.
E&O insurance is the key expense. Errors and omissions insurance for home inspectors costs $1,500-$4,000/year depending on coverage limits and state. This is fully deductible as an ordinary business expense.
Vehicle deduction. Home inspectors drive extensively (15,000-30,000 business miles per year). At $0.70/mile (2025), this produces a $10,500-$21,000 deduction. A dedicated work vehicle (tools in the back, ladder rack) is stronger documentation for 100% business use.
Low employee risk. Most home inspectors operate solo, making the Solo 401(k) available. Inspectors who hire assistants or additional inspectors transition to SIMPLE IRA or SEP IRA.

How does the S-Corp election affect a home inspector?

Hypothetical example

Round numbers. A home inspector earns $90,000 in net profit after all business expenses (vehicle, insurance, tools, continuing education).

As sole proprietor:

Net profit: $90,000
SE tax: $90,000 x 92.35% x 15.3% = $12,710
QBI deduction: 20% x ($90,000 - $6,355) = $16,729
Income tax on $66,916 (before standard deduction): approximately $9,600
Total federal tax: $22,310

As S-Corp (salary $45,000):

W-2 salary: $45,000
Employer FICA: $3,443
Employee FICA: $3,443
Pass-through: $41,558 ($90,000 - $45,000 - $3,443)
QBI deduction: 20% x $41,558 = $8,312
Income tax on $78,246 ($45,000 + $41,558 - $8,312, before standard deduction): approximately $11,800
Total FICA: $6,885
Total federal tax: $18,685

S-Corp savings: approximately $3,625/year.

The reasonable salary of $45,000 is supported by BLS data for construction and building inspectors (median approximately $65,000 for government inspectors, lower for private sector), adjusted for a self-employed inspector who handles scheduling and marketing but has no management responsibilities over staff.

How does the self-employed health insurance deduction work?

Self-employed individuals can deduct 100% of health insurance premiums for themselves, their spouse, and dependents as an above-the-line deduction on Form 1040, Schedule 1. This deduction reduces your adjusted gross income, which lowers your income tax, but it does not reduce your self-employment tax. You can only deduct premiums for months in which you (or your spouse) were not eligible to participate in an employer-subsidized health plan. The deduction cannot exceed your net self-employment income from the business under which the plan is established. For S-Corp shareholders owning more than 2%, the corporation pays or reimburses the premiums, includes them in the shareholder’s W-2 wages, and the shareholder then takes the deduction on their personal return.

What professional liability coverage do home inspectors need?

Errors and omissions (E&O) insurance is essential because home inspection claims typically allege that you missed a defect the buyer later discovered. E&O policies for home inspectors typically cost $1,500-3,000 annually and cover legal defense costs plus settlements or judgments up to the policy limit. General liability covers bodily injury (you damage property during the inspection or someone trips over your equipment) but does not cover claims about your professional opinions. Many states require E&O insurance as a condition of licensure, with minimum coverage amounts ranging from $100,000 to $500,000. The premium is fully deductible as a business expense. Pre-inspection agreements that limit your liability to the inspection fee are common but do not eliminate the need for insurance, since courts do not always enforce those limitations.
