Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES KKR & Co. Inc. is a corporation for U.S. federal income tax purposes and thus is subject to U.S. federal, state and local corporate income taxes at the entity level on KKR’s share of net taxable income. In addition, the KKR Group Partnerships and certain of their subsidiaries operate in the United States as partnerships for U.S. federal income tax purposes and as corporate entities in certain non-U.S. jurisdictions. These entities, in some cases, are subject to U.S. state or local income taxes or non-U.S. income taxes. Prior to the Conversion, KKR & Co. L.P.’s investment income and carried interest generally were not subject to U.S. corporate income taxes. Subsequent to the Conversion, all income earned by KKR & Co. Inc. is subject to U.S. corporate income taxes, which we believe will result in an overall higher income tax expense (or benefit) when compared to periods prior to the Conversion. The Conversion resulted in KKR obtaining a partial step-up in the tax basis of certain assets that will be recovered as those assets are sold or the basis is amortized. On the date of the Conversion, we recorded an estimated net tax benefit and estimated net deferred tax asset of $257.1 million relating to this partial step-up in tax basis. Our overall tax provision is based on, among other things, an estimate of the amount of such partial step-up in tax basis that is derived from an analysis of the basis of our unitholders in their ownership of KKR common units at December 31, 2017, as adjusted by partial information received by KKR for some trades made in KKR common units in 2018. While this information does not completely reflect the actual basis of our unitholders at June 30, 2018, our estimate is based on the most recent unitholder basis information available to us. The amount of partial step-up in tax basis cannot be finally determined until complete trading information with respect to common units of KKR & Co. L.P. for the six months ended June 30, 2018 becomes available. KKR does not currently expect such information to become available until late in the first quarter of 2019 (most likely after our Annual Report on Form 10-K is required to be filed), and the timing and the availability of this information is not within KKR’s control. Since the unitholder basis information currently available to us does not completely reflect the actual basis of our unitholders at June 30, 2018, the amount of partial step-up in tax basis as finally determined is expected to differ, possibly materially, from the current estimate, which in turn is expected to cause KKR’s income tax provision and effective tax rate under GAAP to differ, possibly to a material extent, from the current estimate described herein. If the amount of the partial step-up in tax basis as finally determined is higher than the current estimate, KKR would record a higher net tax benefit and an incrementally greater deferred tax asset, which would have the effect of decreasing the amount of taxes payable by KKR in the future. If the amount of partial step-up in tax basis as finally determined is lower than the current estimate, KKR would record a lower net tax benefit and an incrementally lower deferred tax asset, which would have the effect of increasing the amount of taxes payable by KKR in the future. The effective tax rates were (10.6)% and 4.64% for the three months ended September 30, 2018 and 2017, respectively, and (1.50)% and 3.65% for the nine months ended September 30, 2018 and 2017, respectively. The effective tax rate differs from the statutory rate primarily due to the following: (i) a substantial portion of the reported net income (loss) before taxes is not attributable to KKR but rather is attributable to noncontrolling interests held in KKR’s consolidated entities by KKR Holdings or by third parties, (ii) the tax benefit recognized as a result of the partial step-up in tax basis of certain assets as a result of the Conversion as described above and (iii) certain compensation charges attributable to KKR are not deductible for tax purposes. On December 22, 2017, the 2017 Tax Act was enacted in the United States, which instituted fundamental changes to the taxation of multinational businesses. During the year ended December 31, 2017, the Company estimated that $96.4 million of deferred tax expense, recorded in connection with the remeasurement of certain deferred tax assets and liabilities at the reduced U.S. federal tax rate, and $1.5 million of expense, net of the reversal of the deferred tax liability related to unremitted foreign earnings, recorded in connection with the transition tax on the mandatory deemed repatriation of foreign earnings was a provisional amount and a reasonable estimate in accordance with Staff Accounting Bulletin 118 ("SAB 118"). KKR filed its 2017 U.S. corporate income tax return in October 2018 and the actual tax impacts described above did not differ materially from the provisional amounts recorded in 2017. In accordance with SAB 118, accounting for the effects of the 2017 Tax Act is to be completed within one year of enactment and will be reflected in our financial statements as of and for the year ended December 31, 2018. During the three and nine months ended September 30, 2018, there were no material changes to KKR’s uncertain tax positions and KKR believes there will be no significant increase or decrease to the uncertain tax positions within 12 months of the reporting date.
