Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes All of Charter’s operations are held through Charter Holdco and its direct and indirect subsidiaries. Charter Holdco and the majority of its subsidiaries are generally limited liability companies that are not subject to income tax. However, certain of these limited liability companies are subject to state income tax. In addition, the indirect subsidiaries that are corporations are subject to federal and state income tax. All of the remaining taxable income, gains, losses, deductions and credits of Charter Holdco are passed through to Charter and its direct subsidiaries. For the three months ended March 31, 2015 and 2014, the Company recorded $35 million and $64 million of income tax expense, respectively. Income tax expense is recognized primarily through increases in deferred tax liabilities related to the Company's investment in Charter Holdco, as well as through current federal and state income tax expense and increases in the deferred tax liabilities of certain of our indirect corporate subsidiaries. As of March 31, 2015 and December 31, 2014, the Company had net deferred income tax liabilities of approximately $1.7 billion and $1.6 billion, respectively. Included in net deferred income tax liabilities is net current deferred tax assets of $23 million and $26 million as of March 31, 2015 and December 31, 2014, respectively, which are included in prepaid expenses and other current assets in the accompanying condensed consolidated balance sheets of the Company. Net deferred tax liabilities included approximately $236 million at March 31, 2015 and December 31, 2014, relating to certain indirect subsidiaries of Charter Holdco that file separate federal or state income tax returns. The remainder of the Company's net deferred tax liability arose from Charter's investment in Charter Holdco, and was largely attributable to the characterization of franchises for financial reporting purposes as indefinite-lived. In determining the Company’s tax provision for financial reporting purposes, the Company establishes a reserve for uncertain tax positions unless such positions are determined to be “more likely than not” of being sustained upon examination, based on their technical merits. There is considerable judgment involved in making such a determination. The Company did not have any unrecognized tax benefits as of March 31, 2015 or December 31, 2014. No tax years for Charter or Charter Holdco, for income tax purposes, are currently under examination by the IRS. Tax years ending 2011 through 2014 remain subject to examination and assessment. Years prior to 2011 remain open solely for purposes of examination of Charter’s loss and credit carryforwards.
