Tax help for mobile service businesses in Los Angeles and Santa Clarita
Free tax review
Running your business from your truck?
Fifteen minutes by phone, ending with one written price for what we’d handle.
We work with mobile detailers, pressure washers, window cleaners, junk haulers, dog groomers and signing agents in Los Angeles and Santa Clarita, and remotely anywhere in the US. We do the books, the return with the vehicle done right on both returns, quarterly estimates and helper pay — one flat fee, in writing.
Based in Santa Clarita
We’re based in Santa Clarita and work with mobile service businesses across Los Angeles — Van Nuys, North Hollywood, Pacoima, Sylmar, Canoga Park and Reseda — and remotely anywhere in the US. A detailer based in Santa Clarita who works seven days or more in a calendar year in Van Nuys needs a City of Los Angeles business tax registration too; City-based businesses register regardless. We check it by address and handle the registration’s tax side.
Typical situations
Do you work with a mobile business like mine?
Yes — if you detail cars, pressure wash, clean windows, haul junk, groom dogs or run loan signings from a vehicle in Los Angeles or Santa Clarita and need the books, the return, quarterly estimates or helpers handled.
The mobile detailer leaving from Canyon Country
Driveways in Valencia, Saugus and Sylmar. The swing question is the first drive of the day. Home to the first customer is commuting unless the home office qualifies as the principal place of business; driving customer to customer is business. The usual miss is a log rebuilt in April, or every trip logged as a round trip from home. We check whether it qualifies and set up a log kept as you go, with January and December odometer readings; a phone app counts. The return starts at $650 for a sole proprietor.
The pressure washer in Santa Clarita with a new three-quarter-ton pickup
The truck’s weight rating sits above the passenger-vehicle line, so the federal return can take most or all of it in year one while the California return can’t. The trouble is a truck that’s also the family vehicle: it may not stay mostly a work truck, which the first-year write-off needs. We read the door-jamb sticker, keep both schedules, and plan the first year’s estimates on the bigger California number — talk through the purchase with us.
The notary signing agent driving to closings in Burbank and Glendale
A signing company sends a 1099-NEC — the form reporting non-employee pay — for the whole payment. The notarial part isn’t subject to self-employment tax (Social Security and Medicare tax) under the 2026 Schedule SE instructions; the printing, travel and package-handling part is. Some agents pay self-employment tax on every dollar; others exempt the whole fee. The split is how we apply the rule — no IRS ruling addresses signing fees — built from the notary journal and signing-company statements.
The junk hauler in Pacoima with two helpers paid in cash
A helper hauling on your jobs does your usual business, so California’s ABC test — the employee-or-contractor test — presumes the helper an employee unless all three pass. Cash with no W-9, no payroll, no record can cost the deduction for that pay. Once wages pass $100 in a quarter, we register with the EDD within 15 days, run payroll, and file the returns and W-2s. Helper payroll from $95 a month. Read paying a helper in cash: the risk and how to do it right.
The mobile dog groomer in North Hollywood who also sells shampoo
The groom is a service — no sales tax on the job; you pay tax on the supplies. Selling bottles regularly is retail and needs a seller’s permit, the state’s sales tax license, free from the CDTFA. Supplies ordered out of state with no California tax charged owe use tax; we report it. The usual miss is product sales mixed into service income with no permit; we set up the permit and keep the two apart.
The window cleaner in Canoga Park two years behind
When records are thin, the IRS can treat every bank deposit as income until you show it isn’t. The usual wrong count: transfers between your own accounts, a loan draw or a refund booked as sales. We rebuild the missing months from bank and card statements, pulling transfers, loans and refunds out of the deposits. A cleanup from $750, then monthly bookkeeping — how a catch-up project runs.
The vehicle
Mileage or actual expenses: which is better for a mobile service business?
It depends on the vehicle and the miles, but the choice is made in the vehicle’s first business year: taking the standard mileage rate (a per-mile IRS rate) that first year keeps both methods open later, while a big first-year write-off locks that vehicle into actual expenses (the real costs) for good.
- For 2026 the rate is 72.5 cents a mile through June 30 and 76 cents from July 1, so the log needs the date of every trip
- The rate already covers gas, repairs, insurance and depreciation, so a return claims one method or the other for a vehicle, never both — business parking and tolls are deductible on top
- A crew running five or more vehicles at the same time can’t use the rate
- A van, pickup or panel truck counts as a car for this rule
We figure the deduction both ways in the vehicle’s first year, before the return is filed, and set up the log you’ll actually keep. See how we prepare the return.
The truck
Can I write off the truck or van I use for the business?
Yes — on two schedules: federal law allows the full write-off in year one for a work truck bought after January 19, 2025, while California caps Section 179 (expensing equipment the year you buy it) at $25,000 and allows no bonus depreciation (the extra first-year write-off), so the California return carries its own schedule.
The weight line
The number that counts is the gross vehicle weight rating — the loaded weight the maker rates the vehicle for — on the door-jamb sticker. At 6,000 pounds or less, the 2026 first-year write-off is capped at $20,300 for a vehicle used only for business; above that, the cap doesn’t apply — but the mileage log is still required.
The business-use test
The write-off needs more than 50% business use. If business use later drops to 50% or less, part of it comes back as income.
Before you buy, work through the purchase with us.
The monthly close
What do you check every month?
Every month we check deposits, the mileage log, vehicle costs, helper payments, product sales and the quarter’s estimate.
- Deposits matched to invoices and payment-app and card payouts, with transfers, loans and refunds pulled out
- The mileage log’s monthly total against the odometer readings
- Vehicle costs coded to the method you use
- Supplies and equipment coded, with use tax flagged on out-of-state orders
- Helper payments matched to W-9s and payroll, each contractor’s 2026 total tracked toward the $2,000 1099-NEC line, and the DE 542 checked separately
- Product sales kept on their own line, apart from service income
- For signing agents, the notary journal against the signing companies’ statements
- The quarter’s estimate figured from the books — the last 2026 payment is due January 15, 2027
Each month you get the P&L, the balance sheet and a short note on what needs attention. See how monthly bookkeeping runs.

Where we work
Do you work with mobile businesses outside Santa Clarita?
Yes — across Los Angeles and anywhere in the US, remotely. Burbank, Glendale and Santa Clarita are separate cities from Los Angeles with their own business-tax rules, which we check by address. In the Santa Clarita Valley we can also work in person through our on-site service.
What we don’t do
We handle the tax and money side: the books, the return, quarterly estimates, payroll, and the sales and use tax side. Vehicle-code, water-runoff, insurance, notary-commission and lending-compliance questions, and business licenses and permits beyond the City’s business tax registration, are outside our work, and we don’t advise on them.
Worth reading
What can you read before you call?
Three short reads for an owner who works out of a vehicle.
FAQ
What do mobile service owners ask before booking?
What do I need to file taxes for a mobile service business?
Send last year’s return, bank and card statements, the mileage log or app export, the vehicle purchase or lease papers, any 1099-NEC or 1099-K you received, and W-9s and payment records for helpers. A signing agent also sends the notary journal and the signing companies’ fee statements. We send a checklist so nothing is missed.
How are notary signing agents taxed?
Income tax applies to the whole signing fee. The notarial fees are free of self-employment tax under the 2026 Schedule SE instructions; the rest — printing, driving, handling — is not. The split is our reading; no IRS ruling speaks to signing fees.
How much should I set aside for taxes from detailing or pressure washing?
We figure each quarter’s estimate from your own books, because no flat percentage fits — the right amount changes with the vehicle, helpers and, for a signing agent, the notary split. In a year you buy a truck, California’s share runs higher because California doesn’t follow the federal first-year write-off.
Do I charge sales tax for car detailing in California?
Generally no — a detail is a service, so you don’t charge sales tax on the job; you pay the tax when you buy the soap, wax and chemicals. If you regularly sell products to customers, you need a seller’s permit, which is free from CDTFA.
I paid a helper in cash. Do I have to send a 1099?
If the helper is truly an independent contractor and you paid $2,000 or more in 2026, yes — a 1099-NEC by January 31 or the next business day, and paying in cash doesn’t change that. California’s own report, the DE 542, is due within 20 days on its own trigger, which we check. A regular helper is usually presumed an employee in California, so we look at that first.
Do I need a business license to detail cars in Los Angeles?
On the tax side, yes: inside the City of Los Angeles you need a Business Tax Registration Certificate, and home-based and 1099 businesses are included. A registered business with $100,000 or less in worldwide gross receipts for the prior year owes no City business tax only if it renews on time. Burbank, Glendale and Santa Clarita are separate cities with their own rules. Licenses and permits beyond that tax registration are outside our work.
Do I need an LLC for a junk removal or detailing business?
Not for federal income tax: a one-owner LLC is reported on Schedule C just like a sole proprietor; California adds $800 a year, plus a fee once income passes $250,000. Liability protection is a legal question. We model the decision on your numbers before you form — see our entity-selection page.
