If the fair market value of the automobile exceeds the amount specified in section 4.04(2), the employer may determine the value of the use of the automobile under the general valuation rules of § 1.61–21(b) or under the special valuation rules of § 1.61–21(d) (Automobile lease valuation) or § 1.61– 21(f) (Commuting valuation) if the applicable requirements are met.

April 27, 1998 10 1998–17 I.R.B.

  1. Maximum Automobile Value for Using the Cents-per-mile Valuation Rule.

(1) Amount of Adjustment. Under § 1.61–21(e)(1)(iii)(A), the limitation on the fair market value of an employer-provided automobile first made available to any employee for personal use after 1988 is to be adjusted in accordance with § 280F(d)(7). Accordingly, the adjustment for any calendar year is the percentage (if any) by which the CPI automobile component for October of the preceding calendar year exceeds the CPI automobile component for October 1987 ( See, section 4.02(1).) The new car component of the CPI was 115.2 for October 1987 and 140.6 for October 1997. The October 1997 index exceeded the October 1987 index by 25.4. The Internal Revenue Service has, therefore, determined that the adjustment for 1998 is 22.05 percent (25.4/115.2 � 100%). This adjustment is applicable to all employer-provided automobiles first made available to any employee for personal use in calendar year 1998. The maximum fair market value specified in § 1.61–21(e)(1)(iii)(A) must therefore be multiplied by a factor of 0.2205, and the resulting increase, after rounding to the nearest $100, is added to $12,800 to give the maximum value for 1998. (2) The Maximum Automobile Value. For automobiles first made available in calendar year 1998 to any employee of the employer for personal use, the vehicle cents-per-mile valuation rule may be applicable if the fair market value of the automobile on the date it is first made available does not exceed $15,600.
