RATE ALLOWANCE
.01 In general . (1) The ordinary and necessary expenses an employee pays or incurs in driving an automobile the employee owns or leases in performing services as an employee of the employer are deemed substantiated (in an amount determined under section 9 of this revenue procedure) when a payor reimburses those expenses using a FAVR allowance. A FAVR allowance is a mileage allowance using a flat rate
2009–51 I.R.B. 932 December 21, 2009
a payor reasonably projects an employee will drive a standard automobile during a calendar year. Annual mileage equals the annual business mileage divided by the business use percentage.
(8) Annual business mileage . Annual business mileage is the mileage a payor reasonably projects an employee will drive a standard automobile in performing services as an employee of the employer during the calendar year, but may not be less than 6,250 miles for a calendar year. Annual business mileage equals the annual mileage multiplied by the business use percentage.
(9) Business use percentage . A payor determines the business use percentage by dividing the annual business mileage by the annual mileage. The business use percentage may not exceed 75 percent. In lieu of demonstrating the reasonableness of the business use percentage based on records of total mileage and business mileage driven by employees annually, a payor may use a business use percentage that is less than or equal to the following percentages for a FAVR allowance that is paid for the following annual business mileage:
(b) multiplying the resulting amount by the business use percentage.
(3) Periodic variable payment . A periodic variable payment covers the projected variable costs (including gasoline and all taxes thereon, oil, tires, and routine maintenance and repairs) of driving a standard automobile in performing services as an employee of the employer in a base locality, and must be paid at least quarterly. A payor may compute a periodic variable payment rate for a computation period by dividing the total projected variable costs for the standard automobile for the computation period, determined at the beginning of the computation period, by the computation period mileage. A computation period may be any period of a year or less. Computation period mileage is the total mileage (business and personal) a payor reasonably projects a standard automobile will be driven during a computation period and equals the retention mileage divided by the number of computation periods in the retention period. For each business mile an employee substantiates for the computation period, a payor must make a periodic variable payment at a rate that does not exceed the rate for that computation period.
(4) Base locality . A base locality is the particular geographic locality or region of the United States in which an employee generally pays or incurs the costs of driving an automobile in performing services as an employee of the employer. Thus, for purposes of determining the amount of fixed costs, the base locality is generally the geographic locality or region in which the employee resides. For purposes of determining the amount of variable costs, the base locality is generally the geographic locality or region in which the employee drives the automobile in performing services as an employee of the employer.
(5) Standard automobile . A standard automobile is the automobile a payor selects on which a specific FAVR allowance is based.
(6) Standard automobile cost . The standard automobile cost for a calendar year may not exceed 95 percent of the sum of (a) the retail dealer invoice cost of the standard automobile in the base locality, and (b) state and local sales or use taxes on the purchase of the automobile. The standard automobile cost may not exceed $27,300.
(7) Annual mileage . Annual mileage is the total mileage (business and personal)
Annual business mileage Business use percentage
6,250 or more but less than 10,000 45 percent 10,000 or more but less than 15,000 55 percent 15,000 or more but less than 20,000 65 percent 20,000 or more 75 percent
driven the retention mileage. The Service will accept the following safe harbor residual values for a standard automobile computed as a percentage of the standard automobile cost:
(10) Retention period . A retention period is the period in calendar years a payor selects during which the payor expects an employee to drive a standard automobile in performing services as an employee of the employer before the automobile is replaced. The period may not be less than two calendar years.
(11) Retention mileage . Retention mileage is the annual mileage multiplied by the number of calendar years in the retention period.
(12) Residual value . The residual value of a standard automobile is the projected amount for which it could be sold at the end of the retention period after being

ation or lease payments, maintenance and repairs, tires, gasoline (including all taxes thereon), oil, insurance, license and registration fees, and personal property taxes
.03 FAVR allowance in lieu of fixed and variable costs .
(1) A reimbursement computed using a FAVR allowance is in lieu of the employee’s deduction of all the fixed and
variable costs the employee pays or incurs in driving the automobile in performing services as an employee of the employer, except as provided in section 9.06 of this revenue procedure. Items such as depreci

rates charged in the base locality for insurance coverage on the standard automobile during the current calendar year without considering rate-increasing factors such as poor driving records or young drivers.
(8) A payor may provide a FAVR allowance only to an employee whose insurance coverage limits on the automobile for which the FAVR allowance is paid are at least equal to the insurance coverage limits used to compute the periodic fixed payment under that FAVR allowance.
.06 Employee reporting . Within 30 days after a FAVR allowance initially covers an employee’s automobile, or again covers the automobile if coverage has lapsed, the employee by written declaration must provide the payor with the following information: (1) the make, model, and year of the employee’s automobile, (2) written proof of the insurance coverage limits on the automobile, (3) the odometer reading of the automobile, (4) if owned, the purchase price of the automobile or, if leased, the price at which the automobile is ordinarily sold by retailers (the gross capitalized cost of the automobile), and (5) if owned, whether the employee has claimed depreciation for the automobile using any of the depreciation methods prohibited by section 8.04(1) of this revenue procedure or, if leased, whether the employee has computed deductible business expenses for the automobile using actual expenses. The employee must provide the information in (1), (2), and (3) to the payor within 30 days after the beginning of each calendar year that a FAVR allowance covers the employee’s automobile.
.07 Payor recordkeeping and reporting . (1) The payor or its agent must maintain written records stating (a) the statistical data and projections on which the FAVR allowance payments are based, and (b) the information the employees provided under section 8.06 of this revenue procedure.
(2) Within 30 days of the end of each calendar year, the payor must provide each employee covered by a FAVR allowance during that year with a statement that lists the amount of depreciation included in each periodic fixed payment portion of the FAVR allowance paid during that calendar year to an automobile owner and explains that by receiving a FAVR allowance the employee has elected to exclude the automobile from the Modified Accelerated Cost Recovery System under § 168(f)(1).
are included in fixed and variable costs for this purpose.
(2) An employee may deduct, as separate items, parking fees and tolls attributable to the employee driving the standard automobile in performing services as an employee of the employer. Similarly, an employee may deduct, as a separate item, interest relating to the purchase of the standard automobile to the extent that the interest is an allowable deduction under § 163.
.04 Depreciation . (1) A payor may not provide a FAVR allowance for an automobile for which an employee has (a) claimed depreciation using a method other than straight-line for its estimated useful life, (b) claimed a § 179 deduction, (c) claimed the additional firstyear depreciation allowance under, for example, § 168(k) or § 168(n), or (d) used ACRS under former § 168 or MACRS under current § 168. If an employee uses actual costs for an owned automobile that has been covered by a FAVR allowance, the employee must use straight-line depreciation for the automobile’s remaining estimated useful life (subject to the applicable depreciation deduction limitations under § 280F).
(2) Except as provided in section 8.04(3) of this revenue procedure, the total amount of the depreciation component for the retention period a payor includes in computing the periodic fixed payments for that retention period may not exceed the excess of the standard automobile cost over the residual value of the standard automobile. In addition, the total amount of the depreciation component may not exceed the sum of the annual § 280F limitations on depreciation in effect at the beginning of the retention period that apply to the standard automobile during the retention period.
(3) If the depreciation component of periodic fixed payments exceeds the limitations in section 8.04(2) of this revenue procedure, the Service will treat that section as satisfied if the total annual amount of the FAVR (periodic fixed and variable) payments a payor makes to an employee driving 80 percent of the annual business mileage of the standard automobile does not exceed the business standard mileage rate for that year (under section 5.01 of the applicable revenue procedure) multiplied by 80 percent of the annual business mileage of the standard automobile.
(4) The depreciation included in each periodic fixed payment portion of a FAVR allowance paid with respect to an automobile reduces the basis of the automobile (but not below zero) in determining adjusted basis as required by § 1016. See section 8.07(2) of this revenue procedure for the requirement that the employer report the depreciation component of a periodic fixed payment to the employee.
.05 FAVR allowance limitations . (1) A payor may provide a FAVR allowance only to an employee who substantiates to the payor for a calendar year at least 5,000 miles driven in performing services as an employee of the employer or, if greater, 80 percent of the annual business mileage of that FAVR allowance. If the employee is covered by the FAVR allowance for less than the entire calendar year, the payor may prorate these limits on a monthly basis.
(2) A payor may not provide a FAVR allowance to a control employee (as defined in § 1.61–21(f)(5) and (6), excluding the $100,000 limitation in paragraph (f)(5)(iii)).
(3) A payor may not provide a FAVR allowance if at any time during a calendar year a majority of the employees the FAVR allowance covers are management employees.
(4) A payor may not provide a FAVR allowance to any employee unless at all times during a calendar year FAVR allowances provided by the payor cover at least five employees in total.
(5) A payor may provide a FAVR allowance only for an automobile (a) the employee receiving the payment owns or leases, (b) the cost of which, as a new vehicle (whether or not purchased new by the employee), was at least 90 percent of the standard automobile cost included in determining the FAVR allowance for the first calendar year the employee receives the allowance for that automobile, and (c) for which the model year does not differ from the current calendar year by more than the number of years in the retention period.
(6) A payor may not provide a FAVR allowance for an automobile an employee leases for which the employee has used actual expenses to compute the deductible business expenses of the automobile for any year during the lease period.
(7) The insurance cost component of a FAVR allowance must be based on the
2009–51 I.R.B. 934 December 21, 2009
For example, assume a payor provides an employee an advance mileage allowance of $400 per month plus 20 cents per mile based on an anticipated 2000 miles for a total of $800 (at a time when the business standard mileage rate is 50 cents per mile), and the employee substantiates 1000 business miles. The requirement to return excess amounts is treated as satisfied if the employee is required to return $300, the portion of the allowance that exceeds the product of the standard mileage rate and the miles substantiated ($500).
(3) For a FAVR allowance, the requirement to return excess amounts is treated as satisfied if the employee is required to return, within a reasonable period of time (as defined in § 1.62–2(g)), (a) the portion (if any) of the periodic variable payment received that relates to miles in excess of the business miles the employee substantiates, and (b) the portion (if any) of a periodic fixed payment that relates to a period during which the employee was not covered by the FAVR allowance.
.04 An employee is not required to include in gross income the portion of a mileage allowance received from a payor that is less than or equal to the amount deemed substantiated under section 9.01 of this revenue procedure, provided the employee substantiates in accordance with section 9.02. See § 1.274–5T(f)(2)(i). Assuming that the remaining requirements for an accountable plan provided in § 1.62–2 are satisfied, that portion of the allowance is treated as paid under an accountable plan, is not reported as wages or other compensation on the employee’s Form W–2, and is exempt from withholding and payment of employment taxes. See § 1.62–2(c)(2) and (c)(4).
.05 An employee is required to include in gross income the portion of a mileage allowance received from a payor that exceeds the amount deemed substantiated under section 9.01 of this revenue procedure. See § 1.274–5T(f)(2)(ii). In addition, the excess portion of the allowance is treated as paid under a nonaccountable plan, is reported as wages or other compensation on the employee’s Form W–2, and is subject to withholding and payment of employment taxes. See § 1.62–2(c)(3)(ii), (c)(5), and (h)(2)(i)(B).
.06 If an employee’s substantiated expenses are less than the employee’s actual expenses, the following rules apply:
For automobile lessees, the statement must explain that by receiving the FAVR allowance the employee may not compute the deductible business expenses of the automobile using actual expenses for the lease period.
.08 Failure to meet section 8 require- ments . If an employee receives a mileage allowance that fails to meet one or more of the requirements of this section 8, the employee may not be treated as covered by any FAVR allowance of the payor during the period of the failure. Nevertheless, the expenses to which that mileage allowance relates may be deemed substantiated using the method described in sections 5, 9.01(1), and 9.02 of this revenue procedure to the extent the requirements of those sections are met.
