Mobile Detailing Deductions: The Van That Is the Shop, the Water You Carry, the Ceramic Coating Inventory, and the Insurance a Customer's Car Requires

A mobile detailing business carries its shop to the customer: a van or trailer with a water tank, a pressure washer, a generator, polishers, vacuums, and a cabinet of chemicals and coatings. The tax picture follows the rig. The vehicle is the largest deduction and usually favors the actual-expense method, the equipment on it is depreciated or expensed, the products are supplies or inventory depending on how they are sold, and the insurance that covers a customer's car while you work on it is the premium that distinguishes a business from a hobby.

The van or trailer

A cargo van outfitted for detailing — tank, pump, generator mounts, shelving, graphics — is used almost entirely for business, and its costs are high relative to its mileage, which usually makes the actual-expense method (fuel, insurance, repairs, depreciation, and the build-out) more valuable than the standard mileage rate (72.5 cents a mile for January through June 2026 and 76 cents from July 1, 2026). The van itself, if over 6,000 pounds gross vehicle weight, escapes the passenger-vehicle depreciation caps and qualifies for Section 179 — a cargo van with no seating behind the driver and a short hood can fall outside the $32,000 (2026) Section 179 cap on heavy SUVs — and for 100 percent bonus depreciation, which has no such cap. The upfit — tank, pump, generator, cabinetry — is equipment depreciated separately or expensed under Section 179. A trailer towed behind a personal truck is equipment; the truck's business use is measured by miles and may use either method — but standard mileage must be chosen in the first year the truck is used for business, and claiming Section 179, bonus, or accelerated depreciation on it rules standard mileage out for good.

Trips between customers are always business miles. Trips from home to the first customer and back from the last are business miles when the home is the principal place of business — a home office used regularly and exclusively for scheduling, billing, and bookkeeping, with no other fixed location, qualifies; without one, the first and last trips of the day within the metropolitan area are commuting. Keep the log anyway; it establishes the business-use percentage that the actual-expense method applies.

Equipment and the build

| Item | Treatment | |---|---| | Pressure washer, generator, water tank, pump, hose reels | Equipment; Section 179 or bonus depreciation, or the de minimis safe harbor for items of $2,500 or less per item or invoice | | Polishers, extractors, vacuums, steamers, lighting | Equipment, usually expensed under the de minimis rule | | Water reclamation or filtration system | Equipment | | Paint-correction tools, infrared curing lamps | Equipment | | Towels, pads, brushes, applicators | Supplies when bought | | Shop vacuum filters, generator maintenance | Repairs and maintenance |

Equipment moved from personal to business use — a pressure washer you already owned — starts from the lower of cost or value at conversion.

Chemicals, coatings, and what is inventory

Soaps, degreasers, dressings, and compounds consumed in the service are supplies, deducted when used — which, for a detailer that buys as it goes and keeps no stock records, is effectively when bought; a large stockpile on hand at year-end waits until it is used. Ceramic coating products sold as a premium service are also consumed in the service and are supplies — but if the business sells products to customers (a bottle of detail spray, a maintenance kit), those are inventory, deducted when sold, and taxable sales for sales tax. Businesses meeting the small business gross receipts test ($32 million of average annual gross receipts for 2026) can treat inventory under the simplified rules, but Florida's sales tax rules (below) apply regardless of the federal method.

Insurance

Garage keepers coverage — for damage to a customer's vehicle in your care — plus general liability and commercial auto on the van are the core policies, all deductible. Equipment coverage for the rig's contents, and workers' compensation once there are employees (required in Florida at four or more employees for non-construction businesses, counting owners who are corporate officers or LLC members), follow. Personal auto insurance that excludes commercial use is not a substitute for commercial auto coverage on the van.

Software, payments, and marketing

Booking and routing apps, payment processing fees (deducted from the gross, not netted), website and listing fees, branded uniforms with the logo (ordinary clothing is not deductible), vehicle wraps (advertising — a wrap over the de minimis threshold is technically a depreciable asset, but Section 179 or bonus depreciation still writes it off in the first year), and photography of finished work are all deductible. Fuel surcharges you charge customers are income; fuel is an expense.

Home base and the phone

Supplies stored in a garage, a workbench for equipment repair, and a desk for scheduling can support a home office deduction for the space used regularly and exclusively for the business; the garage bay that also parks the family car does not qualify. The phone plan is deducted at its business share.

Florida sales tax

Florida taxes interior nonresidential cleaning services, but a vehicle is not a nonresidential building; vehicle cleaning falls under the state's repair-and-maintenance rule instead. A plain wash with only detergent or water softener is exempt, but the entire charge for a wash or detail that applies wax, silicones, or any other substance forming a protective film or coating is taxable — which reaches most detailing packages and every ceramic coating job. Products sold to customers are taxable goods. A detailer that also installs items — window tint, paint protection film — furnishes tangible property with the installation, and the entire charge is taxable. Register for sales tax before the first waxed, sealed, or coated job, not only once products are sold.

Worked example. A one-person mobile detailer buys a $48,000 high-roof cargo van (over 6,000 pounds) and spends $14,000 on the water system, generator, and shelving. The van is used 95 percent for business by the log. He deducts $45,600 of the van under Section 179 and bonus depreciation and the $14,000 upfit as equipment in year one, plus fuel, insurance, and maintenance at 95 percent. His $9,000 of chemicals and coating products are supplies. He adds a $900 garage keepers policy and a $2,400 commercial auto policy. Because his packages include wax, sealant, or ceramic coating, he registers for Florida sales tax before the first job, collects tax on the full package price, and buys the waxes and coatings tax-free on a resale certificate; in year two he begins selling maintenance kits, which become inventory and add taxable product sales.
