Interest in FAVR vehicle plans, also known as fixed- and variable-rate reimbursement programs, is growing as employers look for alternatives to taxable car allowances. A standard car allowance may be simple, but it can lead to tax waste and may not reflect employees' actual driving costs. FAVR is more structured and can provide tax-free reimbursement when IRS requirements are met.
Quick answer: A standard car allowance is simpler to administer, but it is usually taxable and may not reflect actual employee driving costs. FAVR is more structured and requires mileage and cost data, but it can be tax-free when IRS requirements are met and may provide more accurate reimbursement across different locations, mileage levels, and vehicle costs.
Standard Car Allowance vs. FAVR Allowances
The purpose of both vehicle plans is to cover the costs of driving a personal vehicle for work. FAVR reimbursements can be tax-free when IRS requirements are met, while a standard flat car allowance is usually treated as taxable income unless it is structured and documented under an accountable plan.
Whether a plan is accountable depends on how rates are derived and whether payments are verified as business expenses. A FAVR plan generates payments based on localized vehicle expense data, whereas a car allowance is not.
A car allowance amount stays the same each month for all employees, regardless of whether their expenses rise or fall. A FAVR plan pays different amounts to different employees based on what the data says their actual driving expenses should be, preventing over- and under-reimbursement.
Pros and cons of standard auto allowance vs. FAVR plan
Advantages of a traditional car allowance:
- Simple to understand and easy to administer
- No calculations or data required
Disadvantages of a traditional car allowance:
- On average, 30 - 40% of payment goes to taxes
- Employer pays taxes as well (payroll taxes)
- Pays an equal amount for unequal expenses
- Prone to under-reimbursement and labor code violations
- Less competitive in the current job market
Advantages of a FAVR reimbursement:
- Can be tax-free when IRS requirements are met and can better reflect employee cost differences
- Accurate payments based on expense data
- Complies with IRS tax rules and state labor codes
- More competitive in the current job market
- May reduce tax waste when replacing a taxable allowance
Disadvantages of FAVR reimbursement:
- Complicated to understand and challenging to administer
- Typically requires a third-party administrator
How fixed and variable rate allowances work
FAVR is short for "fixed and variable rate." The name derives from the two types of expenses drivers experience. Fixed expenses remain stable from month to month. Variable expenses rise or fall more frequently. This vehicle reimbursement approach divides an employee's expenses into these two categories and then reimburses them accordingly.
Fixed expense = fixed payment (i.e., allowance or stipend)
Predictable expenses include insurance, depreciation, vehicle taxes, and license and registration. Using a standard vehicle appropriate to the job and a minimum insurance coverage level, the plan calculates the monthly fixed expenses for each employee, adjusted for zip code. The employee then receives a monthly fixed payment equal to that expense amount. It's like a car allowance but based on data.
Variable expense = variable rate (i.e., cents-per-mile)
Expenses like fuel, maintenance, oil, and tires increase the more a person drives. To address these variable costs, the employer pays a cents-per-mile rate based on a standard vehicle driven within a particular geographic territory, as prices vary by region. This rate is recalculated every few months in response to cost increases or decreases.
This combination can make FAVR one of the more accurate ways to reimburse business vehicle costs because it separates ownership costs from operating costs and adjusts for location. When IRS FAVR requirements are met and business mileage is properly documented, FAVR reimbursements can qualify for tax-free treatment.
FAVR rules are complicated – why switch?
A fixed- and variable-rate car allowance is more complicated than a traditional plan. That's why most companies contract with a specialist to administer the plan. Let's look at three big reasons why it's worth it:
1. FAVR can reduce car allowance tax waste.
For an employee, a $600 allowance easily becomes less than $400 once you factor in income taxes and FICA/Medicare. Plus, the company pays its share of taxes. What if you remove that tax waste and reinvest it? In many cases, reducing tax waste can improve the value employees receive while helping the company better control reimbursement costs.
2. FAVR can help support reimbursement compliance.
FAVR can help support reimbursement compliance by using documented mileage, localized cost data, and a structured reimbursement schedule.
In states or local jurisdictions with employee expense reimbursement requirements, employers should review whether their vehicle reimbursement method adequately covers necessary business driving costs.
3. FAVR pays employees equitably and individually.
No two drivers experience the exact same vehicle costs. Some cover larger or more expensive territories. The larger the company, the wider the gaps between different employees' expenses will be. Yet a standard car allowance pays the same amount to everyone. Because a FAVR plan uses data to calculate vehicle expenses and accounts for miles driven, employees can receive reimbursement that more closely reflects their business driving costs. This can create a more consistent and equitable reimbursement experience.
Would a FAVR auto plan work for my company?
Any organization with at least five participating employees can offer a FAVR reimbursement plan. This approach is also scalable for large companies. Because IRS rules for an accountable program are complicated, it's best to outsource it. But the benefits are often worth it.
Employers should review current IRS guidance each tax year because FAVR requirements, mileage rates, and vehicle value limits can change annually.
FAQs About Car Allowance vs. FAVR
Is FAVR better than a car allowance?
FAVR may be a better fit when employees drive different mileage amounts, work in different territories, or face different local vehicle costs. A standard car allowance may be simpler when driving needs are limited and consistent.
Is a car allowance taxable?
A standard flat car allowance is usually taxable unless it is structured and documented under an accountable plan.
Is FAVR tax-free?
FAVR reimbursements can be tax-free when IRS FAVR requirements are met, including proper mileage documentation and program administration.
Why do employers switch from car allowances to FAVR?
Employers often consider FAVR to reduce tax waste, improve reimbursement accuracy, and account for employee mileage and location differences.
For employers with mobile employees across different territories, mileage levels, or cost regions, FAVR may be worth evaluating against a taxable car allowance.
