Top Companies for Tax-Free Car Reimbursements: FAVR, Motus, Cardata

Four companies dominate the tax-free car reimbursement market, and they split cleanly into two roles. Motus and Cardata design and administer the full IRS-compliant reimbursement programs, using either the Fixed and Variable Rate (FAVR) method or a cents-per-mile structure to keep payments off employees’ W-2s. Everlance and TripLog handle the mileage tracking side, capturing the GPS-based trip data the IRS requires to substantiate every business mile. Companies with large driver populations typically pair a program administrator with a tracking app; smaller employers sometimes use a tracking platform alone alongside an internal reimbursement policy.

What Makes a Reimbursement Tax-Free

Before comparing vendors, it helps to know what any of them has to deliver. The IRS treats a car payment as tax-free only when it runs through an “accountable plan” under Section 62(c) of the Internal Revenue Code and Treasury Regulation 1.62-2. Three conditions apply at the same time:1Office of the Law Revision Counsel. 26 USC 62 – Adjusted Gross Income Defined

  • The expense has a business connection. Personal errands and daily commutes don’t count.
  • The employee substantiates each expense within a reasonable time, logging the date, destination, miles, and business purpose of every trip.2Internal Revenue Service. Travel and Entertainment Expenses Frequently Asked Questions
  • Any payment over the substantiated amount goes back to the employer.

Miss any one, and the whole payment becomes taxable wages. A flat monthly car allowance fails the test on its face, because a fixed check bears no relationship to what an employee actually drove. The IRS reports it in box 1 of the W-2, and both sides owe payroll tax on it.3Internal Revenue Service. Publication 463 – Travel, Gift, and Car Expenses Roughly 30% of a $600 monthly allowance disappears to taxes before the employee sees it. That gap is why the vendors below exist.

The Two IRS-Approved Structures

Providers work in one of two frameworks defined by Revenue Procedure 2019-46.4Internal Revenue Service. Revenue Procedure 2019-46

FAVR splits reimbursement into a fixed monthly payment covering ownership costs (insurance, registration, depreciation) and a variable per-mile payment covering operating costs (fuel, maintenance, tires). Both components are calibrated to local data, so a driver in a high-cost metro receives a different fixed payment than a driver in a rural market. FAVR is the most precise accountable-plan method and the one the IRS treats as the benchmark.

Cents-per-mile (CPM) reimburses a flat rate per business mile up to the IRS standard mileage rate. It’s easier to administer than FAVR but pays every driver the same per-mile amount, which under-reimburses employees in expensive markets. Payments at or below the standard rate under an accountable plan are tax-free; anything above it becomes taxable unless the program is structured as FAVR.

Motus vs. Cardata

Motus is the largest program administrator, running FAVR programs for more than 3,000 companies. The platform calculates reimbursements at the zip-code level, adjusting the fixed and variable components based on local fuel prices, insurance premiums, and maintenance costs. Motus absorbed Runzheimer in a 2018 merger; references to Runzheimer as a separate vendor are outdated.

Cardata sits in the mid-market with over 25 years of compliance history and more than $1 billion in reimbursements processed. Its platform handles program design, mileage capture through its own mobile app, insurance verification, vehicle eligibility monitoring, and payments made directly to drivers rather than through payroll. That last point matters more than it sounds. When reimbursements move through normal payroll channels, the risk of accidental classification as wages goes up. Routing them through a third-party administrator adds an audit-friendly layer of documentation showing the money tracked to substantiated business expenses.

Both vendors handle the ongoing compliance work that makes FAVR impractical to run in-house: verifying that every driver still meets insurance and vehicle-age rules, flagging participants who fall below the 5,000-mile threshold mid-year, and refreshing regional cost data as markets shift. For a fleet of a few hundred or a few thousand drivers spread across multiple states, that oversight is the product.

Everlance and TripLog for Mileage Tracking

Everlance and TripLog provide the trip-capture layer any accountable plan needs. Both use GPS to detect and log trips automatically, replacing the paper logbooks most employees eventually stop maintaining. Everlance sells a “set it and forget it” approach with automatic trip detection and expense categorization. TripLog offers similar automatic tracking plus receipt scanning and time tracking for employers who need to capture hours alongside miles.

The IRS requires date, miles, destination, and business purpose for every trip.2Internal Revenue Service. Travel and Entertainment Expenses Frequently Asked Questions Digital platforms capture the first three automatically; the business-purpose field still needs a driver entry, though recurring routes can be labeled once. Both apps generate compliant reports and store data long enough to cover the federal three-year records retention requirement.5Internal Revenue Service. How Long Should I Keep Records

GPS raises reasonable privacy questions. The practical convention most platforms follow is to activate tracking only when the driver starts a trip and to avoid recording location outside business hours. Everlance gives users explicit control over what data is captured and shared. Any employer using GPS-based tracking should give drivers written disclosure.

2026 Rates and FAVR Eligibility

Two federal numbers set the outer limits for 2026:

The depreciation component built into the 2026 rate is 35 cents per mile, which becomes relevant when an employee later sells a vehicle they claimed business use on.7Internal Revenue Service. 2026 Standard Mileage Rates – Notice 2026-10

FAVR itself carries eligibility rules that disqualify smaller employers and thin-mileage programs:8Internal Revenue Service. Internal Revenue Bulletin 2019-49 – Rev. Proc. 2019-46

  • At least five covered drivers at all times during the calendar year. Drop below five and the plan loses tax-free status.
  • Each driver must substantiate at least 5,000 business miles annually, or 80% of the plan’s assumed annual business mileage, whichever is greater. Mid-year hires get a prorated threshold.
  • The employee’s vehicle must have cost at least 90% of the plan’s standard automobile cost when new, regardless of whether the employee bought it new.
  • The vehicle’s model year cannot differ from the current calendar year by more than the plan’s defined retention period.
  • A majority of covered employees cannot be management at any point during the year.

Insurance is often misread. The IRS does not set specific liability minimums like $100,000/$300,000. Each driver’s personal auto coverage must simply match or exceed the coverage limits the plan itself uses to calculate the fixed payment. The numbers are plan-specific.

The Commuting Trap

The most common failure has nothing to do with software choice. It’s reimbursing commuting miles. The IRS treats a daily drive from home to a regular workplace as personal, regardless of distance or business benefit. Business miles begin only once the employee reaches the first work location and drives to a second one, visits a client, or runs a work-related errand. Trips to a temporary work location, defined as anywhere the employee works for less than a year, also count. If a remote worker’s home qualifies as a principal place of business, trips from home to client sites are business miles, but trips to the employer’s main office remain commuting.

Reimbursing commuting miles violates the business-connection requirement. If the IRS catches it, the whole program can be reclassified as nonaccountable, making every reimbursement taxable for every driver, not only the ones with commuting miles in the mix. Both administrator platforms and the standalone tracking apps offer filters to flag trips between a driver’s home and regular office.

What a Failed Plan Costs

When an accountable plan fails, the employer has to reclassify every payment as wages, report the amounts on affected W-2s, and pay the employer’s share of Social Security and Medicare taxes retroactively.9Internal Revenue Service. Nonresident Aliens and the Accountable Plan Rules Employees owe their share of payroll tax plus income tax on reimbursements they received tax-free.

The IRS can add a 20% accuracy-related penalty on the underpayment under Section 6662 when it stems from negligence, disregard of rules, or a substantial understatement (the greater of 10% of the correct liability or $5,000 for individuals).10Internal Revenue Service. Accuracy-Related Penalty A single compliance failure at a company with hundreds of drivers can generate six- or seven-figure exposure once back taxes, penalties, and interest compound across multiple tax years. That math is why the vendor fees are usually easy to justify.

The FLSA Wage-Floor Angle

Tax status isn’t the only reason to reimburse properly. Under the Fair Labor Standards Act, an employer violates federal law when unreimbursed business driving costs push an employee’s effective pay below minimum wage in any workweek.11U.S. Department of Labor. FLSA2020-12 Opinion Letter A delivery driver earning $10 an hour who spends $80 a week on fuel and wear without reimbursement can drop below the $7.25 federal floor, or a higher state minimum.12U.S. Department of Labor. Fact Sheet 16 – Deductions From Wages for Uniforms and Other Facilities Under the Fair Labor Standards Act

FAVR handles this automatically because the payments are calibrated to actual costs. Cents-per-mile programs at or near the IRS rate cover most drivers adequately. Flat allowances are the weakest option here, because a fixed monthly figure can still leave a driver short in a heavy-mileage week even though the employer technically paid something.
