INCOME TAXES	3 Months Ended

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES ANGI Homeservices is included within IAC’s tax group for purposes of federal and consolidated state income tax return filings. In all periods presented, current and deferred income tax benefit and provision have been computed for the Company on an as if standalone, separate return basis. ANGI Homeservices’ payments to IAC for its share of IAC’s consolidated federal and state tax return liabilities have been reflected within cash flows from operating activities in the accompanying consolidated and combined statement of cash flows. At the end of each interim period, the Company makes its best estimate of the annual expected effective income tax rate and applies that rate to its ordinary year-to-date earnings or loss. The income tax provision or benefit related to significant, unusual, or extraordinary items, if applicable, that will be separately reported or reported net of their related tax effects are individually computed and recognized in the interim period in which they occur. In addition, the effect of changes in enacted tax laws or rates, tax status, judgment on the realizability of a beginning-of-the-year deferred tax asset in future years or income tax contingencies is recognized in the interim period in which the change occurs. The computation of the annual expected effective income tax rate at each interim period requires certain estimates and assumptions including, but not limited to, the expected pre-tax income (or loss) for the year, projections of the proportion of income (and/or loss) earned and taxed in foreign jurisdictions, permanent and temporary differences, and the likelihood of the realizability of deferred tax assets generated in the current year. The accounting estimates used to compute the provision or benefit for income taxes may change as new events occur, more experience is acquired, additional information is obtained or our tax environment changes. To the extent that the expected annual effective income tax rate changes during a quarter, the effect of the change on prior quarters is included in income tax provision in the quarter in which the change occurs. For the three months ended March 31, 2018, the Company recorded an income tax benefit of $4.0 million, which represents an effective income tax rate of 30%. The effective income tax rate for the three months ended March 31, 2018, is higher than the statutory rate of 21% due primarily to excess tax benefits generated by the settlement and exercise of stock-based awards and state taxes, partially offset by unbenefited foreign losses. For the three months ended March 31, 2017, the Company recorded an income tax benefit of $25.9 million due primarily to excess tax benefits generated by the settlement and exercise of stock-based awards. On December 22, 2017, the U.S. enacted the Tax Cuts and Jobs Act (the “Tax Act”). The Tax Act implemented a number of changes that took effect on January 1, 2018, including but not limited to, a reduction of the U.S. federal corporate tax rate from 35% to 21% and a new minimum tax on global intangible low-taxed income earned by foreign subsidiaries. While the Company was able to make a reasonable estimate of the impacts of the Tax Act, certain amounts are provisional as the Company gathers additional data. Any adjustment of the Company’s provisional tax expense will be reflected as a change in estimate in its results in the period in which the change in estimate is made in accordance with Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act, which is also included in the FASB issued ASU No. 2018-05, Income Taxes (Topic 740), Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118, which was issued and adopted by the Company in March 2018. In addition, our estimates may also be impacted and adjusted as the law is clarified and additional guidance is issued at the federal and state levels. No adjustment was made in the three months ended March 31, 2018 to the Company’s provisional tax expense. The Company recognizes interest and, if applicable, penalties related to unrecognized tax benefits in the income tax provision. Accruals for interest and penalties are not material. The Company is routinely under audit by federal, state, local and foreign authorities in the area of income tax as a result of previously filed separate company and consolidated tax returns with IAC. These audits include questioning the timing and the amount of income and deductions and the allocation of income and deductions among various tax jurisdictions. The Internal Revenue Service is currently auditing IAC’s federal income tax returns for the years ended December 31, 2010 through 2012, which includes the operations of the HomeAdvisor business. The statute of limitations for the years 2010 through 2012 has been extended to June 30, 2019, and the statute of limitations for the year 2013 has been extended to March 31, 2019. Returns filed in various other jurisdictions are open to examination for various tax years beginning with 2009. Income taxes payable include reserves considered sufficient to pay assessments that may result from examination of prior year tax returns. We consider many factors when evaluating and estimating our tax positions and tax benefits, which may require periodic adjustments and which may not accurately anticipate actual outcomes. Although management currently believes changes to reserves from period to period and differences between amounts paid, if any, upon resolution of issues raised in audits and amounts previously provided will not have a material impact on liquidity, results of operations, or financial condition of the Company, these matters are subject to inherent uncertainties and management’s view of these matters may change in the future. At March 31, 2018 and December 31, 2017, unrecognized tax benefits, including interest, are $1.6 million and $1.5 million, respectively, for tax positions included in IAC’s consolidated tax return filings. If unrecognized tax benefits at March 31, 2018 are subsequently recognized, income tax provision would be reduced by $1.6 million. The comparable amount as of December 31, 2017 is $1.5 million. The Company regularly assesses the realizability of deferred tax assets considering all available evidence including, to the extent applicable, the nature, frequency and severity of prior cumulative losses, forecasts of future taxable income, tax filing status, the duration of statutory carryforward periods, available tax planning and historical experience. As of March 31, 2018, the Company has a gross deferred tax asset of $80.1 million that the Company expects to fully utilize on a more likely than not basis. However, the tax sharing agreement between ANGI Homeservices and IAC governs the parties’ respective rights, responsibilities and obligations with respect to tax matters, including responsibility for taxes attributable to ANGI Homeservices, entitlement to refunds, allocation of tax attributes and other matters. Any differences between taxes currently due or receivable under the tax sharing agreement and the current tax provision computed on an as if standalone, separate return basis are reflected as adjustments to additional paid-in capital.
