Effective Tax Rates
DT Midstream records income taxes during the interim period using an estimated annual effective tax rate ("ETR") and recognizes specific events discretely as they occur.
The interim period ETRs of DT Midstream are 32% and 23% for the three months ended March 31, 2023 and 2022, respectively. The difference between the interim ETRs and federal statutory rate of 21% is primarily related to state income taxes. The increase in the interim ETRs for the comparative period is driven by remeasurements of state deferred taxes for changes in tax status and apportionment rates.
