For tax years beginning in 2018, you can't claim the credit for oil and gas production from marginal wells because it's completely phased out, per Notice 2019-37. For tax years beginning in 2019, you can claim the credit for natural gas production only, per Notice 2020-34 (the part of the credit for crude oil production remains completely phased out). Partnerships and S corporations must file Form 8904 (Rev. December 2018) and use $0.08 as the credit amount on line 2 to claim the credit for natural gas production in tax years beginning in 2019. All other taxpayers aren't required to complete or file the form if their only source of the credit is a partnership or S corporation. Instead, they can report the credit directly on Form 3800, General Business Credit, Part III, line 1zz. For tax years beginning in 2020, the credit amount, if any, hasn't been determined. We'll post further information here when that determination is made, which may be as late as May 2021.
