Work travel is a reimbursable expense
When an employee uses a personal vehicle for work, the resulting expense is a necessary expenditure incurred in direct consequence of the work or the employer's directions, and section 2802 requires the employer to reimburse it. The principle is the same anti-subsidy rule that governs the rest of the category: the cost of the vehicle use the work requires belongs to the employer, not the employee. The reimbursable expense is not merely the gas burned but the full cost of operating the vehicle for the work travel — fuel, wear, maintenance, depreciation, insurance, and the like attributable to the business miles — because all of these are costs the work imposes on the employee's vehicle. The obligation thus reaches the true cost of the work-related driving, which is why the measurement methods the next section describes are designed to capture the operating cost, not just the fuel.
For a restaurant, the rule applies whenever the work sends an employee onto the road, which happens more than the industry's largely on-site character suggests. A restaurant may require employees to make catering deliveries, run to the bank with deposits, pick up supplies, or travel between two locations of a multi-unit operation — each a work-related vehicle use the employer must reimburse. The obligation is easy to overlook precisely because restaurant work is mostly stationary, so the occasional required errand on an employee's own car can go unreimbursed by default. But the occasional nature of the travel does not exempt it: a required delivery or supply run is reimbursable just as any business travel is, and a pattern of unreimbursed errands across the staff aggregates into the exposure the capstone prices. The sections below set out Gattuso's three reimbursement methods, the role and limits of the IRS rate, the restaurant travel that triggers the obligation and the commute that does not, and the full-indemnity standard that governs whichever method the employer chooses.
Actual cost, mileage rate, or lump sum
Gattuso v. Harte-Hanks Shoppers establishes that an employer may satisfy its section 2802 automobile-expense obligation by any of three methods, and that the choice of method is the employer's. The first is the actual-expense method: the employer reimburses the employee's actual vehicle costs attributable to the business use — a precise but administratively burdensome approach requiring the employee to track and the employer to verify the real costs. The second is the mileage-rate method: the employer reimburses a set rate per business mile, which approximates the per-mile operating cost and is far easier to administer, requiring only a mileage log rather than a full accounting of vehicle costs. The third is the lump-sum method: the employer pays a fixed periodic amount — a car allowance — calibrated to cover the expected business-use costs, which is the simplest to administer but must be set high enough to actually cover the costs it is meant to reimburse. Each method is permissible, and the employer may select the one that best fits its operations.
The flexibility the three methods provide is real but bounded by the requirement, developed in the final section, that whichever method is chosen must fully indemnify the employee — which constrains how each may be used. The actual-expense method indemnifies by definition, since it reimburses the real costs, but its burden makes it impractical for routine restaurant travel. The mileage-rate method indemnifies if the rate genuinely approximates the per-mile operating cost, which is why the IRS rate is commonly used as the rate; but, as the next section explains, the rate must actually cover the costs, not merely be a conventional figure. The lump-sum method indemnifies only if the fixed amount is set high enough to cover the expected costs; a car allowance pegged too low under-indemnifies and fails section 2802, and a lump sum untethered to expected costs risks being treated as disguised compensation rather than a bona fide reimbursement, as the duty page's reimbursement-versus-wage discussion warns. The operator's choice of method is therefore free, but the obligation to fully indemnify polices the execution: each method works only if it actually covers the employee's costs.
Three methods, the employer's choice — but one test governs all of them: the method must fully indemnify. A mileage rate or lump sum that under-covers the real cost fails § 2802.
A convenient figure that must still fully cover
The IRS standard mileage rate — 72.5 cents per mile for 2026 — is the figure most employers use for the mileage-rate method, and for good reason: it is an officially published, regularly updated approximation of per-mile vehicle operating cost, convenient to apply and generally accepted as reasonable. But its status must be understood precisely, because employers routinely overread it. The IRS rate is a benchmark, not a legal floor or safe harbor under section 2802. The statute requires the employer to fully indemnify the employee's actual costs, and the IRS rate satisfies that obligation only insofar as it actually covers those costs. Where an employee's real per-mile operating cost exceeds the IRS rate — because of a less fuel-efficient vehicle, higher local fuel prices, or other cost factors — reimbursing at the IRS rate under-indemnifies, and the employer must cover the difference to satisfy section 2802. The rate is a presumptively reasonable approximation, not a ceiling that caps the employer's obligation at the published figure.
The practical implications cut in two directions, and the operator should hold both. On one hand, using the IRS rate is a sound default that will fully indemnify in the ordinary case, so an employer that reimburses business miles at the current IRS rate, keeps the rate current as it changes, and reimburses tolls and parking separately has a strong, administrable compliance posture for routine travel. On the other hand, the IRS rate is not an absolute defense: an employer cannot rely on it to defeat a claim that an employee's actual costs were higher, and certain circumstances — notably where the employer requires the employee to carry additional insurance, or where a particular employee's costs are demonstrably higher — may render the IRS rate insufficient, requiring a higher reimbursement to achieve full indemnity. The disciplined course is to use the current IRS rate as the default mileage rate, to reimburse tolls and parking on top of it, and to remain open to a higher reimbursement where an employee's actual costs exceed what the rate covers — treating the rate as the strong starting point it is, not the unassailable ceiling employers sometimes assume. The full-indemnity standard, not the IRS table, is the governing rule.
The errand is reimbursable; the commute is not
The travel a restaurant requires sorts into reimbursable business travel on one side and the non-reimbursable commute on the other, and the line is the practical heart of the analysis. Reimbursable business travel includes the catering delivery an employee drives to a client, the bank run with the day's deposit, the supply or grocery pickup when the kitchen runs short, and the drive between two locations of a multi-unit operation — each a vehicle use the work or the employer's directions require, reimbursable by one of Gattuso's methods. Tolls and parking incurred on such work travel are separately reimbursable, on top of the mileage or actual-cost reimbursement, because they are additional necessary expenses the travel imposes. Against these, the ordinary home-to-work commute — the daily drive from the employee's home to their regular work location and back — is not a reimbursable business expense; the commute is treated as a personal cost of getting to work, not a cost incurred in the discharge of the work itself.
The recurring complications cluster at the commute boundary, and two are worth flagging. The first is travel between work sites: while the home-to-first-site and last-site-to-home legs are ordinarily non-reimbursable commute, travel between work locations during the workday — driving from one restaurant of a multi-unit operation to another — is reimbursable business travel, because it is travel in the course of the work rather than commuting to it. An employee who works at two locations in a day commutes to the first and from the last but is reimbursed for the drive between them. The second is the errand appended to a commute: an employee directed to pick up supplies on the way in presents a mixed case, and the reimbursable portion is the additional travel the errand requires beyond the ordinary commute, not the commute itself. The operator's practical approach is to reimburse genuine business travel — deliveries, bank and supply runs, inter-site driving — by the chosen method with tolls and parking on top, to treat the ordinary commute as non-reimbursable, and to reimburse the marginal travel where an errand extends a commute. A mileage log capturing the date, purpose, and distance of each business trip is the documentation that supports the reimbursement and distinguishes it from the commute. The calculator below estimates the mileage-rate reimbursement for the business travel.
The mileage-rate reimbursement
The calculator applies the mileage-rate method — business miles times the rate — and adds separately reimbursable tolls and parking. It reflects only the mileage-rate method; the actual-cost method may yield more and must fully indemnify, and the ordinary commute is excluded. Enter the period's business travel:
Fig. 1. Illustrative only — not a prediction, not typical of any matter, and not advice. The mileage-rate method (Gattuso) applies the rate to business miles; the IRS 2026 benchmark is 72.5¢/mile but is not a floor, and actual cost may be higher and must fully indemnify. Tolls and parking are separately reimbursable; the ordinary commute is excluded. Figures derive entirely from the stated inputs.
The method must actually cover the cost
The unifying standard across all three methods is full indemnification, and it is the standard that determines compliance and exposure alike. Gattuso permits the employer to choose the method but requires that the chosen method actually make the employee whole for the vehicle costs the work imposes; a method that systematically under-covers — a mileage rate below the real per-mile cost, a lump sum too small to cover expected travel, an actual-cost method that omits categories of cost — fails section 2802 regardless of which method it is. The standard reframes the analysis away from the label of the method and toward its sufficiency: the question is not whether the employer used a mileage rate or a lump sum but whether what it paid fully covered the employee's actual costs. This is why the IRS rate, though a sound benchmark, is not a guaranteed defense, and why a lump-sum allowance must be calibrated to expected costs rather than set arbitrarily — the method's adequacy, not its form, is what section 2802 polices.
Where mileage and travel go under-reimbursed, the exposure runs through section 2802 and feeds the capstone. The shortfall — the gap between what full indemnity required and what the employer paid, plus any unreimbursed tolls and parking — across every employee who drove for work and across the limitations period is the principal, and section 2802 adds interest and the mandatory attorney's fees. A restaurant that requires deliveries, bank runs, or inter-site travel and reimburses nothing, or reimburses at a rate below actual cost, generates a reimbursement claim across the affected employees with the category's fee-driven exposure. The remediation mirrors the category's: choose a reimbursement method and confirm it fully indemnifies — most simply, the current IRS rate with tolls and parking on top, adjusted upward where actual costs are higher; maintain mileage logs distinguishing business travel from the commute; and reimburse employees for past under-reimbursed travel. Because the mileage obligation is one instance of the section 2802 indemnity, the mileage component slots into the exposure model and the reimbursement-policy remediation the capstone develops. The operator that reimburses business travel to the point of full indemnity closes the last of the four reimbursement gaps that compose the category's exposure.
