Title 26 › Subtitle Subtitle A— Income Taxes › Chapter 1— NORMAL TAXES AND SURTAXES › Subchapter A— Determination of Tax Liability › Part IV— CREDITS AGAINST TAX › Subpart D— Business Related Credits › § 45I
Gives a tax credit to people who produce oil or gas from marginal wells. The credit is $3 for each barrel of qualifying oil and 50 cents for each 1,000 cubic feet of qualifying gas, multiplied by the producer’s share of the production. Those dollar amounts are cut down (but never below zero) if the reference price is higher than $15 for oil ($1.67 for gas). The cut is proportional to how much the reference price exceeds those amounts compared to $3 ($0.33 for gas). For tax years after 2005, the $3 and 50¢ amounts are increased for inflation using the adjustment factor measured from 2004. The “reference price” for oil is set under section 45K(d)(2)(C); for gas it is the Secretary’s yearly estimate of average wellhead price per 1,000 cubic feet. “Qualifying” oil or gas means domestic production from a qualified marginal well. A well’s annual qualifying production is capped at 1,095 barrels or barrels-of-oil-equivalent. The cap is reduced proportionally for short tax years or for wells that do not produce every day. A qualified marginal well is one treated as marginal under section 613A(c)(6) or one that averages no more than 25 barrels-of-oil-equivalent per day and is at least 95% water. The terms crude oil, natural gas, domestic, and barrel use the meanings in section 613A(e). If a well has more than one owner, your credit is based on your share of the revenue interest. Only holders of operating interests can claim the credit. If the well is eligible for the credit under section 45K, you can only use this credit if you choose not to take the 45K credit.
