2017 Section 43 Inflation Adjustment


Table of Contents

Section 43(b)(3)(B) of the Internal Revenue Code requires the Secretary to publish an inflation adjustment factor. The enhanced oil recovery credit under § 43 for any taxable year is reduced if the “reference price,” determined under § 45K(d)(2)(C), for the calendar year preceding the calendar year in which the taxable year begins is greater than $28 multiplied by the inflation adjustment factor for that year.

The term “inflation adjustment factor” means, with respect to any calendar year, a fraction the numerator of which is the GNP implicit price deflator for the preceding calendar year and the denominator of which is the GNP implicit price deflator for 1990.

Because the reference price for the 2016 calendar year ($38.29) does not exceed $28 multiplied by the inflation adjustment factor for the 2016 calendar year ($28 multiplied by 1.6713 = $46.7964), the enhanced oil recovery credit for qualified costs paid or incurred in 2017 is determined without regard to the phase-out for crude oil price increases.

Table 1 contains the GNP implicit price deflator used for the 2017 calendar year, as well as the previously published GNP implicit price deflators used for the 1991 through 2016 calendar years.

Table 2 contains the inflation adjustment factor and the phase-out amount for taxable years beginning in the 2017 calendar year as well as the previously published inflation adjustment factors and phase-out amounts for taxable years beginning in the 1991 through 2016 calendar years.
