Income Tax Disclosure [Abstract] |
INCOME TAXES | INCOME TAXES Effective Tax Rates We record income taxes during the interim period using an estimated annual effective tax rate and recognize specific events discretely as they occur. The interim period effective tax rates of DT Midstream were 23% for both the three and nine months ended September 30, 2025 and 24% for both the three and nine months ended September 30, 2024. The difference between the interim period effective tax rates and federal statutory rate of 21% is primarily driven by state income taxes. One Big Beautiful Bill Act On July 4, 2025, the OBBBA was signed into law in the U.S., which contains a broad range of tax reform provisions that amend, eliminate and extend tax rules under the Inflation Reduction Act. Impacts to the Company of the OBBBA include permanent reinstatement of bonus depreciation on qualified property and modifications to the calculation for excess business interest expense limitation to the current tax estimate. The impact will defer the payment of a portion of our current federal tax for multiple years, but because our tax provision is based on both current and deferred tax, the impact to our income statement is not material. The impact of tax law changes on the Company’s financial statements could differ from its estimates due to further analysis of the new tax law, regulatory guidance or other considerations.
