A recap of Cardata's live webinar, "Navigating Reimbursement Options for Your Fleet: Acing the Inclusion of Personal Vehicles"

Companies with company-provided vehicle fleets are increasingly shifting some or all of their drivers to vehicle reimbursement programs (VRPs) that use personal vehicles instead. In this webinar, Cardata's Lee Adam and Griffin Demer-Henshaw broke down the three IRS-recognized tax-free reimbursement models — cents-per-mile (CPM), tax-free car allowance, and fixed and variable rate (FAVR) — and explained how to determine which drivers belong on which program, how to manage a compliant transition, and how one recent transition delivered a 30% cost reduction against baseline fleet costs.

Does Every Employee on the Road Really Need a Company Car?

The core question framing the webinar: fleet vehicles are well suited to specific situations, but they don't fit every work-related driving scenario — especially given today's cost environment. Company-provided vehicles still make the most sense when:

• Employees need specialty vehicles to do their jobs (delivery vehicles, commercial trucks, tankers) — these can't be replaced by a personal vehicle program
• Branded vehicles serve a marketing purpose — pooled or individually assigned vehicles with company branding carry a marketing investment that's harder to replicate through reimbursement
• Usage thresholds financially justify a company vehicle compared to reimbursement alternatives, once real driving data is understood

Outside of those cases, a fleet vehicle often represents an expensive, inflexible way to enable field employees to do work-related driving.

Why Vehicle Reimbursement Is Growing

Several cost and inflation trends are accelerating the shift toward reimbursement models:

• The average fleet vehicle collision costs $70,000 annually, and a fleet of 1,000 vehicles saw $1 million in damage costs in 2021 alone — a figure that has only grown with subsequent inflation
• 44% of companies with fleets cite rising costs as their top challenge
• Personal-use mileage represents roughly 25% of the average employee's driving on a company vehicle, but chargebacks for that personal use are typically minimal — meaning roughly 30 cents of every dollar spent on fleet vehicles is lost when they're used in the wrong scenario
• Company-owned or leased fleets carry unpredictable costs (accidents, insurance changes, procurement delays) that are difficult to budget for year over year, unlike the more predictable, usage-based costs of a reimbursement program

The Three Tax-Free Reimbursement Methods (U.S.)

Cents-Per-Mile (CPM)

Best suited for occasional or low-mileage drivers — generally under 5,000 miles per year. CPM pairs a driver-submitted mileage total with a flat per-mile rate, most commonly the IRS standard mileage rate (67 cents per mile in 2024, updated annually). Paid at or below that rate, reimbursement is 100% tax-free.

The catch: because the IRS standard rate is a national average, it doesn't account for regional cost differences in fuel, maintenance, or insurance. Above 5,000 miles per year, CPM can significantly over- or under-pay drivers depending on their location — some drivers have been reimbursed as much as $40,000 annually under CPM before switching to a fairer model.

Tax-Free (Accountable) Car Allowance

Governed by IRS Publication 463, this option allows companies to pay a simple flat monthly stipend without the more detailed compliance requirements of FAVR. It can be up to 100% tax-free, but taxability is measured differently: mileage is multiplied by the IRS standard rate and compared to the actual allowance paid. Amounts above that equivalent are taxed; amounts at or below it are not. This method works well for standardizing a flat rate across a department, though it leaves more room for taxability than FAVR.

Fixed and Variable Rate (FAVR)

Described in the webinar as the "star of the show," FAVR is the recommended model for high-mileage drivers — those driving over 5,000 miles per year. FAVR combines:

• A fixed payment covering ownership costs (depreciation, insurance, license, and registration), typically based on 71.4% business-use allocation — reflecting five out of seven days of the week — with flexibility up to 75%
• A variable payment covering operating costs (fuel, maintenance, tires) based on actual regional driving costs

Because FAVR rates are built using market cost data specific to a driver's location and vehicle type, it's considered the fairest and most cost-efficient model — and the only one of the three that allows reimbursement above the IRS standard rate equivalent while remaining fully tax-free.

FAVR Compliance Requirements

To reimburse tax-free under FAVR, a program must meet several IRS requirements:

• The 5,000-mile minimum for eligible drivers
• A minimum of five drivers enrolled in the program (an IRS regulation)
• Verified driver insurance coverage matching the reimbursed insurance costs — reimbursing for coverage a driver doesn't actually carry can be treated as taxable income
• Reasonable vehicle age thresholds, to avoid reimbursing for depreciation on a vehicle that's already fully depreciated
• A standard vehicle profile that reasonably reflects the vehicles actually being driven

If a driver falls out of compliance, the consequence isn't a full loss of tax-free status — it's a recalculation against the IRS standard rate, similar to how a tax-free car allowance is measured. Only the difference, if any, becomes taxable.

Canada vs. U.S.: Key Differences

The IRS and Canada's CRA handle tax-free reimbursement differently:

• CPM, tax-free car allowance, and FAVR are all IRS-governed programs specific to the United States
• In Canada, the CRA offers tiered per-kilometer rates that are 100% tax-free — for example, a higher rate for the first 5,000 km and a lower rate thereafter, varying by province
• FAVR-style reimbursement is used in Canada as well when companies want to offer more precise, fair-market rates, but tiered CRA rates are generally the most straightforward path to full tax-free compliance
• Unlike the U.S., using a tiered variable rate structure outside the standard CRA guidance is uncommon and not typically viewed favorably from a compliance perspective

Real-World Example: A 30% Cost Reduction

The webinar walked through a case study involving a 220-driver fleet with an estimated annual cost of $2.2 million — roughly $10,000 per driver, notably lower than typical fleet costs for a program that size (and not accounting for variable costs like post-accident insurance changes). After transitioning drivers to a FAVR-based personal vehicle reimbursement model, the average per-driver cost dropped to approximately $7,000 per year — a 30% reduction compared to baseline fleet costs.

Building a Hybrid Program: Matching Drivers to the Right Model

Not every driver in an organization has the same needs, and hybrid programs — combining CPM, FAVR, and tax-free allowances for different employee segments — are common. One example shared in the webinar involved segmenting drivers as follows:

• Under 1,000 miles/year (rare drivers, often back-office staff): continued manual mileage submission, given low fraud/mismanagement risk
• Under 5,000 miles/year: moved to a CPM program for fairness and simplicity
• Over 5,000 miles/year (previously submitting mileage manually): transitioned to FAVR
• Company car drivers over 25,000 miles/year: gradually transitioned to FAVR as each vehicle's lease term ended, avoiding disruption mid-lease

This phased approach allowed the organization to exit its fleet vehicle commitments gradually while keeping the transition predictable and low-risk for employees.

Another customer example highlighted a "driver's choice" approach: after building a personalized reimbursement program, the company gave existing fleet drivers the option to switch to a personal vehicle model. 60% of the driver population chose to move from fleet vehicles to a FAVR-based personal vehicle program — demonstrating strong employee preference when given the choice.

Implementation: Three Steps

1. Design a program suited to the organization's driver population, budget, industry standards, and real-time cost data
2. Deploy mileage capture technology — mobile tracking apps used by drivers, which the webinar noted typically save drivers about one week of manual work per year compared to manual tracking, while improving accuracy (automated mileage capture shows an average 25% reduction in reported mileage compared to manually submitted totals)
3. Reimburse tax-free, ideally managed directly by a reimbursement partner to avoid adding administrative burden internally

Ongoing program management matters too — regular business reviews against KPIs like mileage minimums, tax compliance status, year-to-date spend, and industry benchmarking help keep a program optimized as costs and regulations shift.

What About Electric Vehicles?

FAVR can also be used strategically to incentivize EV adoption without requiring a full fleet-wide EV purchase. Two approaches were discussed:

• Reimburse based on a standard combustion-engine vehicle profile while the employee actually drives an EV — since EV operating costs are lower, the employee effectively keeps more of the variable reimbursement, creating a built-in incentive
• Build a dedicated EV-based FAVR rate, with a higher fixed component (reflecting higher acquisition cost) and lower variable component (reflecting lower operating cost)

FAQ: Vehicle Reimbursement Programs

What's the best cost-saving method when switching from company vehicles to reimbursement?FAVR typically delivers the highest ROI for this transition, since it's calculated using real regional cost data and carries a low likelihood of overpayment — unlike CPM using the IRS standard rate, which can overpay high-mileage drivers.

What's the main difference between U.S. and Canadian reimbursement programs?U.S. programs (CPM, tax-free car allowance, FAVR) operate under IRS guidance, while Canada's CRA offers its own tiered per-kilometer tax-free rates. FAVR can still be used in Canada for fair-market rates, but tiered CRA rates are the more standard compliance path.

What happens if a driver falls out of FAVR compliance?The program doesn't lose its tax-free status entirely — reimbursement is recalculated against the IRS standard rate, and only any excess above that equivalent becomes taxable.

Does it make sense to switch a fleet to electric vehicles?FAVR can be structured to incentivize EV adoption — either by reimbursing at a combustion-engine baseline while the employee drives a lower-cost-to-operate EV, or by building a dedicated EV rate profile — without requiring a full fleet EV purchase upfront.

How do companies transition a fleet to a hybrid or full reimbursement model while under existing fleet contracts?The recommended approach is to start planning early relative to lease and contract timelines, working with a reimbursement partner to align vehicle turnover, program design, and driver communication with existing contractual obligations.
