Operating a trucking fleet in Southeast Los Angeles County, whether you run 2 trucks or 20, means navigating a complex set of bookkeeping and compliance obligations specific to motor carriers. California's AB5 law has fundamentally changed how trucking companies must classify drivers. The IFTA (International Fuel Tax Agreement) requires quarterly fuel tracking by state for fleets that cross state lines. Your books must track per-vehicle maintenance, fuel consumption, and profitability so you know which trucks and which routes are paying. And your payroll must comply with California employment law, which treats most truck drivers as employees, not independent contractors. This guide covers the bookkeeping fundamentals for trucking fleet operators in California, distinguishing fleet operations from owner-operator trucking.
This article is written for fleet trucking companies with multiple trucks and employed drivers. If you are an independent owner-operator with a single truck, see our owner-operator trucking bookkeeping guide. For a broader look at contractor bookkeeping in California, see our contractor bookkeeping guide.
AB5 and Driver Classification: Why Your Drivers Are Likely Employees
Until a few years ago, trucking was one of the few industries where California allowed independent contractor relationships to work, especially for owner-operators and some long-haul drivers. California's AB5 law, passed in 2019 and upheld in court, changed that. It applies a strict ABC test to determine whether a worker is an employee or an independent contractor. For most trucking companies, the result is that drivers must be classified as W-2 employees, not contractors.
The ABC test. Under AB5, a worker is presumed to be an employee unless the company can prove all three of the following: (A) the worker is free from control and direction of the company in performing the work, (B) the worker performs work in an occupation or business that is typically offered to the public outside of the company's usual course of business, and (C) the worker is independently established in that occupation or business. For a truck driver working for a trucking company, the test almost always fails. A driver who drives a company truck, operates under the company's dispatch and authority, follows the company's routes and schedules, and has no independent trucking business outside of work for the company cannot pass parts A, B, or C of the test. That driver is an employee.
Port drayage and the trucking exemption. The trucking industry, particularly port drayage operators (who move containers in and out of ports), fought AB5 in federal court on the grounds that it conflicted with federal motor carrier law. As of 2026, the legal challenges have not succeeded, and AB5 applies to trucking in California. Port drayage companies, intermodal operators, and freight carriers all operate under AB5 classification requirements. There is no blanket exemption for the trucking industry; classification is determined on a driver-by-driver basis using the ABC test.
Misclassification risk and EDD enforcement. California's Employment Development Department (EDD) has made trucking company misclassification a priority for audit and enforcement. If the EDD audits your payroll and discovers that drivers you classified as independent contractors should have been employees, you face back payroll taxes (including employer withholding, Social Security, Medicare, SDI, and EDD contributions), penalties, and interest. The EDD can calculate the obligation back several years, making the liability substantial. A trucking company with 5 drivers misclassified for 2 years can face a bill in the hundreds of thousands of dollars in back payroll taxes alone.
Owner-operator leases. Some trucking companies operate by leasing trucks to owner-operators who own the vehicle and provide their labor. A properly structured owner-operator lease can pass the AB5 test if the owner-operator operates independently, maintains their own insurance, and can refuse loads or work for other companies. However, these arrangements are heavily scrutinized by the EDD and must be genuine, not a disguised employment relationship. If the company controls the driver's route, schedule, and operations, it is employment, not a lease, regardless of what the contract says. Consult a labor attorney before entering into owner-operator lease arrangements.
IFTA: Multi-State Fuel Tax Tracking and Quarterly Filings
IFTA stands for the International Fuel Tax Agreement. It is an agreement among states and Canadian provinces to simplify fuel tax reporting and collection for motor carriers that operate in multiple states. If your trucking company operates trucks in more than one state (which includes many fleets operating in and out of California), you must register for an IFTA license and file quarterly IFTA returns.
How IFTA works. When you buy fuel, you pay the state fuel tax where you purchase the fuel. When you consume fuel in a different state, you owe that state's fuel tax. IFTA reconciliation calculates what you paid in each state versus what you owe in each state, and a net payment or refund is due quarterly. For example, if your fleet purchased 10,000 gallons of fuel in California and consumed only 8,000 gallons in California (consuming 2,000 gallons in Nevada), you paid too much California fuel tax and are owed a refund. IFTA reconciliation determines that refund and calculates what Nevada tax you owe on the fuel consumed there.
IFTA registration and licensing. Most states issue an IFTA license based on a simple application. Once you register, you receive an IFTA license plate that goes on the motor vehicle. You must then file a quarterly IFTA return reporting the total gallons of fuel purchased by state and the total gallons of fuel consumed by state. This information must be accurate, because IFTA filings are subject to audit by state fuel tax agencies.
Fuel tracking by state. The heart of IFTA compliance is accurate fuel tracking by state. Most trucking companies use fuel cards (WEX, Comdata, or similar) issued to each truck or to the drivers. The fuel card statement shows the date, location (state), gallons, and amount for each fuel purchase. Your bookkeeper receives the monthly fuel card statement and reconciles it by state, categorizing each purchase by the state where the fuel was purchased. At the end of the quarter, the purchase data by state is used to prepare the IFTA return.
Odometer and mileage tracking. Some states also require mileage data for IFTA reporting, so you must track the total miles operated in each state. Modern fleet management systems capture GPS data and calculate miles by state automatically. If you use manual odometer records or GPS, the data must be organized to support the IFTA filing. Any large gap between fuel purchased and fuel consumed (which is calculated using miles and fuel economy) triggers questions and may result in an audit.
Fuel Card Management and Reconciliation
A fuel card is essential for any trucking fleet. It allows drivers to purchase fuel at authorized pumps without cash or personal payment, and it provides a detailed transaction record for bookkeeping and IFTA purposes.
Selecting and configuring a fuel card. The major fuel card providers for trucking fleets are WEX, Comdata, and Love's card. These cards are accepted at most truck stops and fuel retailers. When you set up the card, you can configure controls such as limiting the card to fuel purchases only (to prevent non-fuel expenditures), setting daily spend limits per driver or vehicle, and setting up automated cost code or vehicle tagging so each purchase is recorded with the truck it belongs to.
Monthly reconciliation. The fuel card issuer provides a detailed monthly statement showing each transaction: date, location (city and state), gallons, amount, and sometimes the vehicle ID or driver ID. Your bookkeeper matches this to the vendor invoice and to your QuickBooks records. The statement is reconciled by vehicle and by state, so IFTA data can be extracted. Any discrepancies (a purchase that does not appear in the statement, or a statement transaction that has no corresponding QuickBooks entry) must be investigated and corrected. This reconciliation must be complete and accurate before IFTA filings are prepared.
Flagging personal fuel purchases and non-fuel charges. If a driver uses the fuel card to purchase fuel for personal use, or if a non-fuel transaction slips through (a restaurant charge, for example), it must be caught during reconciliation and corrected. Personal fuel purchases should be reimbursed by the driver, not expensed by the company. Mischaracterizing personal use as business fuel overstates vehicle operating costs and pollutes the IFTA data, creating audit risk.
Per-Vehicle Tracking: Maintenance, Repairs, and Depreciation
A trucking fleet's profitability depends on per-vehicle economics. You need to know the total cost per mile for each truck so you can identify which vehicles are efficient, which are eating profit due to high maintenance, and when it makes sense to replace or sell a vehicle.
Setting up per-vehicle cost centers. In QuickBooks, each truck should be set up as a separate cost center or customer record (depending on the setup). All costs associated with that vehicle, fuel, maintenance, repairs, insurance, registration, tolls, and driver payroll (if tied to a vehicle) get assigned to that vehicle's record. At the end of a month or quarter, QuickBooks generates a profit and loss by vehicle showing revenue generated (if applicable) and costs incurred. This tells you the net cost per mile for that vehicle.
Scheduled maintenance. Trucks require routine maintenance: oil changes, air filter replacement, tire rotation, brake inspection. This should be tracked on a maintenance schedule and recorded in QuickBooks by vehicle. Scheduled maintenance is a predictable expense and should be budgeted. When maintenance is deferred due to cash constraints, the truck's reliability and safety suffer, and larger repairs result. Most trucking companies build scheduled maintenance into their operating budget based on age and mileage of the fleet.
Repairs vs. improvements. When a truck needs work, the bookkeeper must classify the expense correctly. A routine repair (replacing a worn tire, fixing a brake) is an expense. A capital improvement (replacing the entire brake system, upgrading the transmission) may be capitalized and depreciated. The IRS has strict rules on this, but the general rule is that repairs maintain the asset in its current condition, while improvements extend its life or improve its value. If in doubt, consult your tax accountant.
Depreciation by vehicle. If a vehicle is owned (not leased), it is depreciated over its useful life. Under current law, heavy trucks are depreciated over 5 years (though bonus depreciation, discussed below, allows faster deductions). QuickBooks tracks depreciation expense by asset, so you can see the depreciation cost per vehicle, which contributes to the total cost per mile. If you claim bonus depreciation on a newly purchased truck, that accelerates the deduction into the purchase year.
Lease vs. Own: Operating Leases and Purchase Decisions
Trucking companies can lease trucks (operating lease, where the lessor retains ownership and you pay a monthly fee) or purchase them outright. Each has different bookkeeping and tax implications.
Operating leases. Under an operating lease, the lessor owns the truck and you pay a monthly lease payment. The entire lease payment is fully deductible as a business expense in the month paid. There is no depreciation deduction because you do not own the asset. Operating leases are often attractive because the monthly payment is predictable and includes maintenance and insurance, reducing the unknown costs of ownership. The downside is that you have less flexibility and may pay more over time than purchasing. From a bookkeeping perspective, lease payments go into a simple Lease Expense account and are fully deductible.
Purchase financing. If you purchase a truck, you record the purchase as a fixed asset and depreciate it. If you finance the purchase with a loan, the loan payments are principal and interest. Only the interest portion is deductible; the principal is repayment of the asset. Depreciation expense is also deductible. Under bonus depreciation (now restored at 100 percent), you can deduct the full cost of a newly purchased qualifying truck in the year it is placed in service. This provides a large upfront tax deduction but accelerates income timing, which may affect your tax position. Consult your CPA on whether to claim bonus depreciation or standard depreciation for your truck purchases.
Per-vehicle analysis. The decision to lease or own is financial, not just bookkeeping. A simple analysis compares the total cost of a 5-year lease to the total cost of purchasing and operating a truck for 5 years (including financing, depreciation, maintenance, and eventual resale). Most trucking companies end up with a mix, leasing some trucks for flexibility and owning others where utilization and mileage are predictable. Your bookkeeper should track costs by vehicle so that analysis is possible.
Payroll Compliance for Truck Drivers
Most truck drivers in a fleet are W-2 employees. California requires quarterly payroll filings with the Employment Development Department, federal payroll tax deposits, and accurate wage and withholding tracking.
Wage and hour rules for drivers. California's wage and hour laws apply to truck drivers. The state minimum wage applies, and many cities in Southeast Los Angeles County have set their own higher minimum wages. Overtime is generally required at 1.5 times regular pay for hours over 8 in a day or 40 in a week. Some drivers, especially long-haul drivers, may be covered under federal motor carrier wage and hour rules, which differ from state rules. Consult your payroll provider or accountant on the correct wage classification for your drivers.
Payroll filings and deadlines. California employers file the DE 9 (Quarterly Contribution Return and Report of Wages) with the EDD each quarter. The filing deadline is the last day of the month following the quarter. Missing deadlines triggers EDD penalties and interest. Your bookkeeper should reconcile payroll records to QuickBooks before each filing, ensuring that gross wages, withholdings, and employer contributions are accurate.
Employer payroll taxes. As an employer, you are responsible for State Unemployment Insurance (SUI, currently 3.4 percent on the first 7,000 dollars of each employee's wages for new employers), Employment Training Tax (ETT, 0.1 percent), federal FUTA (6 percent on the first 7,000 dollars, reduced by SUI credit to 0.6 percent for most employers), federal Social Security (6.2 percent), and Medicare (1.45 percent). Confirm current rates with the EDD and IRS, as rates change annually.
Per-Trip Profitability: Calculating Cost Per Mile and Bid Prices
To bid freight rates profitably, a trucking company must know its true cost per mile. This includes fuel, driver wages, maintenance, insurance, and a portion of fixed costs like office rent and administration. Different load types (local delivery, long-haul, specialized freight) have different cost profiles, and a load that looks profitable at the headline rate may be unprofitable when all costs are factored in.
Identifying cost components. For a given trip, the direct costs include fuel, driver wages, tolls, and per-diem (if applicable). Supporting costs include maintenance allocated per mile, insurance per vehicle, licensing, and dispatch. Fixed costs like office overhead are allocated to all trips. A complete per-trip analysis captures all of these, either by formula or by software that tracks them.
Profitability by route or customer. Modern trucking software can assign revenue and costs to trips, routes, or customer contracts, so you can see which routes are profitable and which are losing money. If a particular customer or route consistently shows poor margins, that is a signal to renegotiate rates or to stop pursuing that work. Without per-trip profitability tracking, you may find yourself doing high-volume work that is eating your profit margin without realizing it.
Common Bookkeeping Mistakes for Trucking Fleets
Treating drivers as contractors when they are employees. This is the single most expensive mistake. Misclassification leads to back payroll taxes, penalties, and interest, often running into six figures for a small fleet.
Not tracking fuel by state. If your IFTA fuel data is inaccurate or incomplete, the IFTA filing is wrong and audit risk is high. Fuel tracking by state is non-negotiable for multi-state fleets.
Combining all fleet costs without per-vehicle breakdown. If all fuel, maintenance, and depreciation are lumped into one account without per-vehicle detail, you cannot identify which vehicles are inefficient or which routes are unprofitable. This prevents data-driven decisions about fleet management.
Not reconciling fuel cards to QuickBooks monthly. A fuel card statement that sits unreconciled for months creates a gap between actual costs and recorded costs, which eventually has to be reconciled (often painfully at year-end), and prevents accurate per-vehicle cost tracking.
Deferring maintenance to preserve cash. A truck that needs maintenance but does not get it is a truck headed toward a breakdown, which costs far more than scheduled maintenance. From a bookkeeping perspective, this creates volatility in maintenance expense and understates true vehicle cost.
