In connection with the sale of equity interests to Texas Transmission in 2008, we became a partnership for U.S. federal income tax purposes, and the temporary differences that gave rise to the deferred taxes will, over time, become taxable to the equity holders. Under a tax sharing agreement among us and our equity holders (see Note 1), we make payments to the equity holders related to income taxes when amounts would have become due to the IRS if Oncor was taxed as a corporation. Accordingly, as the temporary differences become taxable, we will pay the equity holders. In the event such amounts are not paid under the tax sharing agreement, it is probable that this regulatory liability will continue to be included in Oncor’s rate setting processes. Accounting For Uncertainty in Provision in Lieu of Income Taxes The statute of limitations is open for our partnership tax returns for the years beginning after December 31, 2017.  Texas margin tax returns are under examination or still open for examination for tax years beginning after 2016.  We are not a member of any consolidated federal tax group and assess our liability for uncertain tax positions in our partnership returns. We had a negligible amount of uncertain tax positions in 2021 and none in 2020. Noncurrent liabilities included a negligible amount of accrued interest related to uncertain tax positions at December 31, 2021 and none at December 31, 2020. There was a negligible amount recorded related to interest and penalties in the years ended December 31, 2021, and none in the years ended December 31, 2020 and 2019, respectively. The federal income tax benefit on the interest accrued on uncertain tax positions, if any, is recorded as liability in lieu of deferred income taxes.
