N.D. Admin. Code § 81-09-02-18 — Method for calculating the tax rate on gas

The gas tax rate will be calculated by the following method: 1. An annual average of the gas fuels producer price index, commodity code 05 -3, as published by the United States department of labor, bureau of labor statistics, will be calculated by dividing the sum of the monthly gas fuels producer price index for January through December of the previous calendar year by the denominator of twelve, with the resultant rounded to one place after the decimal. 2. The gas base rate adjustment will be calculated by dividing the annual average of the gas fuels price index by the denominator of 75.7, with the resultant rounded to six places after the decimal. 3. The gas tax rate will be calculated by multiplying $.04 times the gas base rate adjustment, with the resultant rounded to four places after the decimal.
