A single flatbed can run $85,000 to $150,000 before you've added a winch, a wheel-lift, or a light bar. A rollback for heavy-duty recovery can top $250,000. Most new towing operators finance that truck, start booking calls, and don't think about their books again until January — by which point they've mixed personal fuel purchases with fleet fuel, buried impound storage fees inside "miscellaneous income," and left thousands of dollars in legitimate depreciation on the table because nobody set up a schedule when the truck was placed in service.
Towing is a capital-intensive, heavily regulated business hiding inside what looks like a simple service call. The revenue mix is genuinely complicated — a single job can generate a base tow fee, a mileage charge, a dolly or winch-out fee, an after-hours surcharge, and then, if the vehicle isn't reclaimed same-day, a second and entirely separate revenue stream from daily storage. Get the accounting wrong and you'll misprice jobs, misjudge which service lines actually make money, and hand the IRS deductions you were never required to give up.
Why Towing Bookkeeping Doesn't Look Like a Typical Service Business
Most local service businesses have one revenue stream and a handful of vehicle expenses. A towing company runs three businesses at once:
- Consensual/private-party towing — AAA and roadside-assistance contracts, dealership and repair-shop relationships, direct customer calls. Paid per job, often on 30- to 45-day contract terms with fleet clients.
- Non-consensual/police-rotation towing — accident recovery and abandoned-vehicle removal dispatched by law enforcement. Paid per job at municipally regulated rates, often with strict documentation requirements.
- Impound and storage — the vehicle sits on your lot accruing a daily fee until the owner (or their insurer) reclaims it, or it goes to lien sale.
Each of those three lines has a different cost structure, a different regulatory ceiling on what you can charge, and a different collections timeline. Lumping them into one "towing revenue" account in your chart of accounts makes it impossible to see which one is actually profitable — and impound revenue in particular is easy to under-report if you're not reconciling your lot log against your books every month.
Building a chart of accounts that separates the three revenue lines
At minimum, split revenue into:
- Tow fees (by category: private-party, motor club/contract, police rotation)
- Mileage and dolly/winch-out charges
- Storage/impound fees
- Administrative and lien-sale fees
- Fuel surcharges
On the expense side, separate truck-level costs (fuel, maintenance, insurance) from lot-level costs (rent, security, utilities for the impound yard) so you can see the true cost of running storage versus running trucks. A single blended "vehicle expense" account hides which specific truck — or which specific revenue stream — is actually carrying the business.
Tow Truck Depreciation: The Deduction Most Owners Set Up Wrong
Depreciation is where towing bookkeeping diverges hardest from a typical small business, because the tax code treats tow trucks generously — but only if you set the schedule up correctly the year you place the truck in service.
The GVWR threshold is the whole ballgame. Section 179 vehicle deduction limits depend entirely on Gross Vehicle Weight Rating:
- Passenger vehicles under 6,000 lbs GVWR are capped at a modest first-year Section 179 deduction.
- "Heavy" vehicles between 6,000 and 14,000 lbs GVWR get a higher — but still capped — first-year limit.
- Vehicles over 14,000 lbs GVWR, or trucks modified for nonpersonal use (which most flatbeds and wheel-lifts are, by design), are generally treated like other business equipment: no Section 179 vehicle cap applies at all.
Most light- and medium-duty tow trucks clear 14,000 lbs once you add the bed, winch, and recovery equipment — which means the truck plus its towing equipment can often be fully expensed in the year it's placed in service, subject to the overall Section 179 limit and business-income limitation, rather than depreciated over five or more years. Combine that with 100% bonus depreciation on qualifying property, and a profitable year can absorb a truck purchase almost entirely as a current-year deduction instead of a multi-year write-off.
The catch: the schedule has to start the year you buy the truck. If you don't set up a depreciation schedule (or elect Section 179) in the tax year the vehicle is placed in service, you generally can't go back and retroactively claim it for a prior year — you're stuck depreciating from whatever point you actually record it. This is the single most common mistake in towing bookkeeping: a truck sits on the books as an undepreciated asset, or worse, its full purchase price gets expensed incorrectly as a current operating cost, because nobody logged it as a fixed asset when the invoice came in.
Practical rule: the moment you take delivery of a truck, record it as a fixed asset with its in-service date, GVWR, and cost basis (including winch, light bar, and any recovery equipment bolted on at purchase) before you file that year's return — not after.
Impound Lot Storage: Revenue That's Easy to Under-Book
Storage fees are a real, separate profit center — and one of the easiest to lose track of, because the cash often shows up in dribs and drabs as vehicles get reclaimed over days or weeks, long after the tow itself was invoiced.
Typical fee structure, which varies significantly by state and municipality:
- The initial tow/recovery fee: commonly $150–$400 for a standard non-consensual tow.
- Daily storage: commonly $30–$100 per day, accruing from the day the vehicle enters the lot.
- Administrative/paperwork fees: commonly $50–$200, often set by the municipality rather than the operator.
Because storage accrues daily but is only collected — and only recognized as revenue — when the vehicle is released or sold at lien sale, it's easy for a lot to be quietly full of vehicles generating fees that never make it into the books until cash actually changes hands. Reconcile your physical lot log (vehicle in, vehicle out, days stored, fee schedule applied) against your accounting records monthly, not just at tax time. A vehicle sitting on the lot for 45 days that finally gets picked up should show up as a lump of accrued storage revenue that matches your log — if it doesn't, either the lot log or the books have a gap.
Lien-sale vehicles need their own line entirely: track towing and storage costs advanced against the vehicle, the sale proceeds, and any shortfall you're eating versus any surplus you may be legally required to remit to the former owner (many states require this, and mishandling it is a common source of towing-industry lawsuits).
Compliance Costs Most Owners Underprice
Towing is one of the more heavily regulated small-business categories, and the compliance layer is easy to underprice into your job rates because it doesn't show up as a line item on any single invoice.
- Licensing: many states require a separate towing-specific license beyond a standard commercial driver's license or general business license — some (like Illinois) require an additional certification specifically for non-consensual tows.
- Insurance: minimum liability requirements vary sharply by state, and jurisdictions with active predatory-towing enforcement often require far higher coverage than the general minimum — a real cost difference if you operate across state lines.
- Rate caps: a growing number of states are actively legislating maximum towing and storage fees for non-consensual tows, with new consumer-protection rules taking effect through 2026. If you operate in a state tightening these rules, your allowable non-consensual revenue per job may be shrinking even as your truck, insurance, and labor costs rise — which makes tracking cost-per-tow by job type essential to knowing whether police-rotation work is still worth the truck-hours.
- Background checks and permits: several states require background checks or motor carrier permits specifically for tow operators, on top of standard commercial licensing.
None of these show up as "cost of the tow" on a customer invoice, but they're real annual costs — license renewals, insurance premiums, permit fees, compliance training — that should be allocated back across your job volume so you actually know your fully-loaded cost per tow, not just your fuel-and-labor cost per tow. A company that only prices to fuel and driver time is quietly losing money on every regulated job.
Keep Your Books as Organized as Your Dispatch Log
A towing business runs on precise records — which truck, which job, which fee schedule, which day the vehicle left the lot. Your accounting should be held to the same standard.
