Home Inspector Bookkeeping California: CREIA Licensing, Mileage, Equipment, and Tax Guide

Home inspectors in California run lean service businesses with a set of bookkeeping challenges that most accounting software defaults do not handle out of the box. You drive to every job, carry equipment worth thousands of dollars, pay for professional certifications and errors-and-omissions insurance, and collect fees from real estate agents, buyers, or both. If you have grown past solo work and bring on other inspectors, California AB5 almost certainly requires you to treat them as W-2 employees, not 1099 contractors. And because you have no products to sell, no inventory, and no cost of goods sold, the financial statements that look right for a retailer will not look right for you without some adjustment to how your chart of accounts is structured.

Each of these pieces creates a bookkeeping decision. If your mileage is not logged daily with the required details, the deduction is at risk in an audit. If your E&O premium is expensed as a lump sum in the month it is paid rather than spread across the policy period, your monthly income statement gives you a distorted picture of your actual overhead. If your infrared camera is not on a depreciation schedule, you may be understating your deductions every year.

This guide covers the bookkeeping decisions that matter most for solo home inspectors and small home inspection companies in Downey, Norwalk, Whittier, Paramount, Bell Gardens, and across Southeast Los Angeles County. It is general bookkeeping guidance and does not constitute legal or tax advice. For your specific situation, consult a CPA, a California employment attorney, or the relevant agency directly.

CREIA and ASHI Certification: What Gets Deducted

California does not license home inspectors at the state level the way it licenses contractors or real estate agents. What your professional standing rests on instead is industry certification, primarily through CREIA (California Real Estate Inspectors Association) and ASHI (American Society of Home Inspectors). These organizations set competency standards, require continuing education, and provide the professional designations that buyers, sellers, and real estate agents look for when vetting an inspector.

From a bookkeeping standpoint, the question that matters is what you can deduct. CREIA and ASHI membership dues, annual renewal fees, and exam fees for initial certification or additional specializations are generally deductible as ordinary and necessary business expenses under IRS Code Section 162. The same applies to continuing education courses required to maintain your certification standing. These are costs directly tied to maintaining the professional credentials your income depends on.

Track these in a dedicated expense account, something like "Professional Dues and Certifications," rather than lumping them into miscellaneous expenses. Keeping them separate makes it easier to see your total professional development cost each year and gives you clean support if you are ever asked to substantiate the deduction. For inspectors who hold both CREIA and ASHI credentials, or who maintain multiple specialty designations (pool and spa, infrared, mold assessment), the aggregate cost across renewals and courses can be meaningful.

One area where you should hedge: if you paid a large initial exam or credentialing fee that arguably establishes a new qualification rather than maintaining an existing one, the IRS treatment can be less clear. Some education expenses that qualify a person for a new trade or profession are not deductible, while costs to maintain existing qualifications are. Consult a CPA to confirm how any unusually large credentialing cost is treated in your specific entity and tax situation.

Association conference registrations, industry event fees, and training workshops tied to maintaining or advancing your inspection competencies are also deductible as business education or professional development costs. Keep receipts and document the business purpose of each.

Inspection Fee Income: Per-Inspection and Retainer Revenue

Home inspection is a service business. There is no inventory, no cost of goods sold, and no product revenue to reconcile. Your income chart of accounts should reflect how you actually bill: typically per-inspection fees, and in some cases monthly retainer arrangements with real estate offices, property managers, or investors who use you regularly.

Per-inspection fees. A per-inspection fee is the simplest revenue type to handle. Under accrual accounting, you recognize the income on the date the inspection is performed, regardless of when you collect payment. If a buyer's agent books an inspection on June 10 and you collect the fee on June 12, the income belongs to June 10. If you have not collected by month-end, you have an accounts receivable. Under cash-basis accounting (common for solo inspectors on QuickBooks Simple Start), you recognize the fee when you receive payment. Either method works, but be consistent: your bookkeeping method should match your tax return method, and switching requires IRS approval in most cases.

Keep per-inspection fees in a dedicated revenue account. Separate them from any ancillary charges (radon test add-ons, sewer scope fees, pool inspections, or reinspection fees) so you can see which service lines are contributing to your revenue and price each one correctly.

Monthly retainer income. Some inspectors arrange monthly retainers with real estate offices or property management companies: a flat monthly fee in exchange for a guaranteed number of inspections or priority availability. Retainer income has a deferred revenue element. If you are paid a monthly retainer in advance for a scope of services you have not yet delivered, the payment is a liability, not income, until you have performed the agreed work. Recognize the retainer ratably over the period it covers. If you collect a $2,400 retainer in January covering 12 months of on-call availability and monthly inspections, recognize $200 per month as the obligation is fulfilled, not the full $2,400 in January. Misrecognizing retainer income inflates your quarterly income for the period of collection and understates it for the periods of actual service delivery.

No cost of goods sold. Home inspection is a pure service business. You have no inventory, no materials sold to clients, and no COGS line. Do not create a COGS account in your chart of accounts for inspection fees. Your direct costs, such as consumables like radon test kits, printed forms, batteries, and disposable gloves, are operating expenses (supplies), not COGS. Structuring your books this way keeps your gross margin and income statement accurate and avoids confusion when you hand financials to a lender, CPA, or bookkeeper.

Vehicle Expenses: Mileage Log, Standard Rate, and Actual Method

Your vehicle is your most significant day-to-day expense as a home inspector. Every job requires driving to a property, and depending on where you work in Southeast Los Angeles County, your routes can cover substantial distances across Downey, Norwalk, Whittier, Paramount, Bell Gardens, and surrounding communities. Getting the vehicle deduction right requires both choosing the correct method and maintaining the documentation the IRS requires.

Standard mileage rate. For 2025, the IRS standard mileage rate for business use was $0.70 per mile. The 2026 rate had not been confirmed at the time of publication; verify the current rate directly with the IRS before using any figure in your estimated tax calculations or annual filing. Under the standard mileage method, you multiply your total business miles for the year by the applicable rate, and that figure is your vehicle deduction. It is simpler and requires less record-keeping than the actual method, but the deduction is bounded by the rate and your mileage, which can be limiting if your vehicle is expensive to operate.

Actual expense method. The actual expense method deducts the real cost of operating the vehicle: fuel, insurance, maintenance, repairs, registration, and depreciation, multiplied by the percentage of time the vehicle is used for business. If your vehicle is used 85 percent for business and 15 percent personally, you deduct 85 percent of total vehicle operating costs. The actual method can produce a larger deduction for high-cost or heavily used vehicles, but it requires more record-keeping and a consistent business-use calculation.

Choosing a method. The method you use in the first year you place a vehicle in service generally locks you in for that vehicle. If you start with the standard mileage rate, you can switch to actual in a later year (with some restrictions). If you start with actual, you generally cannot switch to standard mileage for that vehicle. This is a decision worth discussing with a CPA in the year you acquire each vehicle, not after the fact.

The mileage log is non-negotiable. Regardless of which method you use, the IRS requires a contemporaneous mileage log for every business trip. A contemporaneous log means you record each trip at or near the time it occurs, not at the end of the year from memory. Each entry should include the date, the starting location and destination, the business purpose (for example: "Home inspection, 1234 Elm St., Norwalk, booked by [agent name]"), and the odometer reading at the start and end. A mileage-tracking app (MileIQ, Everlance, TripLog) that uses GPS to record trips automatically is the most defensible approach because it removes the reliance on memory and creates a timestamped log. Back up your mileage log monthly.

Personal commutes are never deductible. Driving from home to your first inspection is generally a personal commute if your home is not your qualified business location. If you have a qualified home office (covered in its own section below), the analysis changes, but confirm this with a CPA before claiming home-to-first-job mileage as business mileage.

E&O and General Liability Insurance Premiums

Errors and omissions (E&O) insurance is an operating necessity for home inspectors. A missed material defect, a report that misstates a condition, or an inspection that overlooked a structural issue can trigger a buyer claim months or years after the transaction closes. E&O insurance covers you against professional liability claims arising from the inspection itself. General liability insurance covers bodily injury or property damage that occurs during the inspection, such as a client or agent who is injured at the property during your inspection, or damage you cause to the property in the course of your work.

Both E&O and general liability premiums are deductible as ordinary and necessary business expenses. There is no ambiguity on this point: insurance directly required by your profession and tied to your business operations is a standard business deduction. Track each policy separately in your chart of accounts ("E&O Insurance Expense" and "General Liability Insurance Expense") so you can see what each coverage costs and make informed decisions when policies come up for renewal.

Prepaid premiums and monthly matching. Most home inspectors pay insurance premiums on an annual basis, sometimes with a single upfront payment or through installments. If you pay a full annual E&O premium in January, the correct bookkeeping treatment is to record the payment as a prepaid insurance asset and expense one-twelfth of the annual premium each month. This prevents January from showing a spike in expenses that distorts that month's income statement and keeps your monthly overhead figures accurate for pricing and cash flow planning. If you pay monthly installments, expensing each installment as it is paid achieves the same matching effect without the prepaid asset step.

If your CREIA membership includes any bundled insurance component, separate the membership dues portion from the insurance premium portion in your books so each is categorized correctly.

Equipment Depreciation: Infrared Cameras, Moisture Meters, and Field Tools

Home inspectors carry a meaningful amount of specialized equipment. An infrared (thermal imaging) camera used for detecting moisture intrusion, heat loss, and electrical anomalies can cost $1,000 to $5,000 or more. Moisture meters, radon test kits, combustible gas detectors, electrical testers, and ladders round out a toolkit that represents a significant capital investment. How you account for that equipment affects your deductions every year you use it.

Capitalization versus immediate expensing. Equipment with a cost above your set capitalization threshold is a capital asset to be depreciated, not an immediate expense. Most small businesses set a capitalization threshold at $2,500 (the IRS safe harbor for tangible property under the "de minimis" rule) or lower. Equipment costing less than your threshold in a given invoice is expensed in the period of purchase. Equipment above the threshold is capitalized and depreciated. Confirm your capitalization threshold with a CPA and apply it consistently.

Section 179 expensing. Section 179 of the Internal Revenue Code allows businesses to deduct the full cost of qualifying equipment in the year it is placed in service, up to an annual dollar limit set by the IRS. For a home inspector purchasing an infrared camera or moisture meter, Section 179 can mean a full deduction in the year of purchase rather than spreading it over the asset's recovery period. The annual Section 179 limit is adjusted periodically; verify the current limit with the IRS or your CPA before planning purchases around it. California does not fully conform to the federal Section 179 limits, so your California deduction in the year of purchase may be different from your federal deduction, which requires tracking both separately.

MACRS depreciation. If you do not use Section 179, or if your purchases exceed the Section 179 limit, equipment is depreciated under MACRS (Modified Accelerated Cost Recovery System) over an IRS-designated recovery period. Most inspection tools and equipment fall into the five-year or seven-year MACRS property class. MACRS uses accelerated depreciation, so deductions are larger in the early years of the asset's life. Keep a fixed asset register for every piece of equipment: purchase date, cost, in-service date, depreciation method, and accumulated depreciation to date.

Consumables are not depreciated. Items that are used up in the course of an inspection, such as radon test kanisters (if single-use), printed inspection forms, batteries, disposable gloves, and marker tags, are supplies expenses, not capital assets. Expense them in the period of purchase. Track consumable costs as a separate supplies account distinct from your capital equipment accounts.

The right depreciation approach depends on your specific purchases, your tax situation in a given year, and California conformity rules. Coordinate with a CPA to confirm the most advantageous path for your equipment spending, especially in years when you make large equipment purchases.

Home Office Deduction: Dispatching From Home

Most solo home inspectors operate out of their homes. There is no separate office location: you schedule inspections from home, write reports from home, store equipment at home, and dispatch directly to job sites. If you meet the IRS requirements for a home office deduction, a portion of your housing costs becomes a deductible business expense.

The core requirement is that you use a specific area of your home regularly and exclusively for your business, and that this space is your principal place of business. For a home inspector who has no other office location, writes reports and manages the administrative side of the business from a dedicated space at home, and stores equipment there, the requirement is generally met. The space does not need to be a separate room, but it must be a defined area used only for business, not a kitchen table you also use for personal meals.

Simplified method. The IRS simplified method allows a flat deduction per square foot of your dedicated home office space, up to a maximum square footage set by the IRS. The rate and cap are set by the IRS and should be verified for the current tax year. The simplified method requires less documentation and calculation.

Actual expense method (Form 8829). The actual method calculates the business-use percentage of your home (the square footage of the dedicated office space divided by total home square footage) and applies that percentage to your actual home costs: rent or the allocated mortgage interest and property taxes, homeowner's or renter's insurance, utilities, and home depreciation if you own. The calculation is done on IRS Form 8829 and attached to your return. The actual method typically produces a larger deduction, but requires more record-keeping and introduces home depreciation tracking, which has implications when you sell the home.

The home office deduction cannot be used to create or increase a net business loss in most cases. It is limited to your net business income. Consult a CPA before claiming the deduction, especially in years when your business income is lower than usual or if you are considering selling your home.

California AB5: Hiring Other Inspectors

If your inspection business has grown to the point where you bring on other inspectors to handle volume, California AB5 is the single most important compliance issue you face. AB5, which took effect in 2020, applies a strict ABC test to determine whether a worker is a W-2 employee or an independent contractor. For home inspection companies, the test almost universally resolves in favor of employee status for licensed inspectors performing inspections on your behalf.

Under the ABC test, a worker is presumed to be an employee. To classify a worker as an independent contractor, you must satisfy all three parts:

Part A requires that the worker is free from your control and direction in how the work is performed. If you assign inspection appointments, provide the inspection report format, set the inspection fee, manage the client relationship, or supervise how inspections are conducted, Part A fails. Most home inspection company owners exert exactly this kind of control.

Part B requires that the worker performs work outside the usual course of your business. Home inspection is the business you are in. A licensed inspector performing home inspections on behalf of your company is doing the core thing your company exists to deliver. Part B almost certainly fails. This is the provision of AB5 that makes contractor status most difficult for home inspection companies: there is no structural way around the fact that inspection is your primary service.

Part C requires that the worker is customarily engaged in an independently established trade or business of the same nature as the work performed. An inspector who works primarily for your company, uses your scheduling and report systems, and is not independently marketing inspection services to other clients does not have an independently established business in the sense AB5 requires.

The narrow scenario where contractor status may hold is an inspector who genuinely operates an independent inspection business: they market to their own clients, maintain their own E&O insurance, set their own fees, and work for multiple companies without financial dependence on any one of them. Even in that scenario, the analysis is fact-specific and must satisfy all three parts of the ABC test. The safe default, and the one the California Employment Development Department will apply if it audits your payroll, is W-2 classification. The cost of an employment attorney consultation before classifying a worker as a contractor is far less than the cost of EDD back taxes, penalties, and interest if the classification is later overturned.

For a full walkthrough of the AB5 ABC test, see the California W-2 vs. 1099 bookkeeping guide.

1099-K and 1099-NEC: What You Receive and What You Issue

Home inspectors interact with two different 1099 forms, and confusing them is a common bookkeeping mistake. One is issued to you. The other is issued by you. Both involve income reporting, but they arise in different situations and create different obligations.

1099-K: forms you receive from payment processors. If you accept payment through a third-party payment network such as Stripe, Square, PayPal, Venmo for Business, or a similar processor, the payment processor is required to issue you a 1099-K when your transactions through that platform exceed the applicable reporting threshold. The 1099-K threshold has changed significantly in recent years and is in a period of ongoing adjustment. Verify the current reporting threshold directly with the IRS before assuming whether you will or will not receive a 1099-K for a given tax year. More importantly: regardless of whether a 1099-K is issued, all inspection fee income you receive is taxable and must be reported on your return. Do not assume that income below the 1099-K threshold is not reportable. It is.

When you receive a 1099-K, verify that the total matches your own records of what you received through that processor for the year. Processors report gross transaction amounts, which may include payments you later refunded. If the 1099-K total exceeds your net income from that processor, document the discrepancy and discuss it with your CPA before filing.

1099-NEC: forms you issue to subcontractors. If you pay a subcontractor (another inspector, a report writer, or any individual performing services for your business) $600 or more in a calendar year, and that person is not a corporation, you are generally required to issue them a 1099-NEC by January 31 of the following year and file a copy with the IRS. Collect a completed IRS Form W-9 from every subcontractor before the first payment to ensure you have the name, address, and taxpayer identification number needed to complete the 1099-NEC accurately. Waiting until January to collect W-9s from people you paid all year is a common avoidable mistake. Make W-9 collection the first step before issuing any subcontractor payment.

Note that the obligation to issue a 1099-NEC does not mean the subcontractor relationship is legally a contractor relationship under California AB5. Whether you are required to issue a 1099 and whether the worker is properly classified as a contractor are two separate questions. You can be obligated to issue a 1099-NEC for a payment to someone who, under AB5, should have been a W-2 employee. The 1099 obligation follows the payment; the classification obligation follows the nature of the work relationship.

Quarterly Estimated Taxes for California Home Inspectors

If you operate your home inspection business as a sole proprietor, single-member LLC taxed as a sole proprietor, partnership, or S-corporation with pass-through income, you owe quarterly estimated taxes to both the IRS and the California Franchise Tax Board. These are advance payments against your projected annual tax liability, calculated from your net business income after deductible expenses.

Federal (IRS) payment schedule: April 15, June 15, September 15, and January 15 of the following year. The IRS generally expects quarterly payments if you expect to owe at least $1,000 in federal tax for the year after credits and withholding. Your estimated payment is based on your expected net income: total inspection fees collected, minus deductible expenses including mileage, insurance, equipment depreciation, supplies, professional dues, and home office costs.

California (FTB) payment schedule: April 15, June 15, and January 15 of the following year. California uses a 30/40/0/30 payment schedule. Thirty percent of your estimated annual California tax liability is due April 15. Forty percent is due June 15. No payment is due in September. The remaining thirty percent is due January 15. There is no California estimated tax payment in September, which catches many small business owners off guard after they become accustomed to the federal four-payment schedule. This 30/40/0/30 structure is stable and well-established; it is not subject to the same annual confirmation uncertainty as IRS rates and thresholds.

Self-employment tax. If you are a sole proprietor or single-member LLC taxed as a sole proprietor, your net business income is also subject to self-employment tax, which covers Social Security and Medicare on your own earnings. Self-employment tax is in addition to income tax and must be factored into your quarterly estimated payment calculations. The self-employment tax rate and the income thresholds for the Social Security component are set by the IRS and should be verified for the current year. Using a stale rate in your calculations can lead to underpayment penalties.

Why bookkeeping accuracy matters here. Your quarterly estimated payment amounts are only as good as your books. If your mileage log is incomplete, your vehicle deduction is understated and your net income is overstated, making your estimated payments too high. If your equipment is not on a depreciation schedule, the same problem occurs. If you are receiving retainer income and recording the full amount as current-period revenue rather than spreading it over the earned period, your income is front-loaded and your first-quarter estimates will be too high. Accurate books produce accurate estimated tax calculations and keep you clear of underpayment penalties from both the IRS and the FTB. For a full guide to the mechanics of California quarterly taxes, see the California quarterly estimated taxes guide.

CalSavers: If You Have W-2 Employees

Solo inspectors with no employees are not subject to CalSavers. But if you have grown to the point of having one or more W-2 employees and you do not offer a qualifying employer-sponsored retirement plan (a 401(k), SEP-IRA, or SIMPLE IRA), you are required to enroll in California's CalSavers program.

CalSavers is a state-administered payroll-deduction IRA program. You register as an employer, and employee contributions are withheld from wages each pay period and remitted to the program. Employees are automatically enrolled at the default contribution rate but may opt out or change their contribution rate. The employer's obligation is administrative: set up the program, facilitate withholding, and remit contributions. CalSavers does not require employer contributions on top of wages.

There is no minimum employee count before CalSavers applies. One W-2 employee is enough to trigger the obligation. The enrollment deadline starts running from the date you first have a W-2 employee without an existing qualifying retirement plan. Penalties for non-enrollment escalate over time: the California Department of Industrial Relations has authority to impose per-employee penalties that compound for each pay period the employer is out of compliance.

If you already offer a qualifying employer plan such as a 401(k) or SEP-IRA, you are exempt from CalSavers as long as the plan remains active. If you terminate the qualifying plan, the CalSavers obligation is triggered at that point. For enrollment details and a step-by-step guide to setting up CalSavers, see the CalSavers employer guide for California.

Common Bookkeeping Mistakes Home Inspectors Make

No mileage log, or a log that is reconstructed at year-end. The IRS requires a contemporaneous mileage log. A log written from memory in December for a year of driving does not meet the standard. Use a mileage app to capture trips in real time. The GPS record is harder to dispute than manual entries and requires almost no additional effort once the app is set up.

Expensing the full insurance premium in the month of payment. Annual E&O and general liability premiums paid upfront belong in a prepaid insurance asset account, with one-twelfth expensed each month. Expensing the full payment in January makes that month look far more expensive than it actually was on a per-month basis and distorts your income statement for planning and pricing purposes.

No fixed asset register for equipment. An infrared camera purchased in 2023 and still in active use in 2026 should be on a depreciation schedule. If it was expensed in full in 2023 using Section 179 and is still in use, that is fine, but it should be documented. If it was not expensed in 2023 and there is no depreciation record, you may have missed years of deductions. A fixed asset register is the document that prevents this.

Recording retainer income as fully earned when received. A retainer paid in advance for future inspections is deferred revenue until those inspections are performed. Recording the full retainer as income in the month of collection overstates income for that period and understates it for the months the work is actually done.

Treating other inspectors as 1099 contractors without legal review. Under California AB5, the ABC test almost certainly requires W-2 classification for licensed inspectors performing inspection services for your company. Issuing 1099-NEC forms to inspectors doing your core work does not make them contractors under California law. The EDD's misclassification audit process is thorough, and the look-back period can create substantial retroactive liability.

Failing to collect W-9s before paying subcontractors. You cannot accurately complete a 1099-NEC without the payee's legal name, address, and taxpayer identification number. Collect a signed W-9 before the first payment to any individual or unincorporated business you pay for services.

Lumping consumables with capital equipment. Radon test kanisters, batteries, printed forms, and similar items used up in the course of an inspection are supplies expenses, not capital assets. Mixing them with equipment in your chart of accounts muddies your depreciation schedule and your operating cost figures.
