Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES On December 22, 2017, the U.S. government enacted a comprehensive tax legislation, commonly referred to as the U.S. Tax Cuts and Jobs Act (the “2017 Tax Act”). The primary impact of the 2017 Tax Act in fiscal year 2018 is a reduction of the Company’s federal statutory tax rate from 35% to 28% and taxation of the accumulated unremitted earnings of the Company’s foreign subsidiaries (“Repatriation Tax”). Accumulated unremitted earnings are taxed at a rate of 15.5% to the extent of the aggregate foreign cash position of the Company’s foreign subsidiaries and a rate of 8% to the extent that accumulated unremitted earnings exceeds the aggregate foreign cash position. The 2017 Tax Act allows the Company to elect to pay the Repatriation Tax in eight annual interest free installments beginning in September 2018, although for accounting purposes the Company recorded our provisional estimate of the entire Repatriation tax in the second quarter of fiscal year 2018. The 2017 Tax Act has other provisions that will significantly impact the Company beginning in fiscal year 2019, including a further reduction of the federal statutory tax rate to 21% and provisions such as Global Intangible Low Tax Income and Base Erosion Anti-Abuse Tax that may impact taxation of the Company’s international earnings. The Company is still considering the impact of these provisions on its effective tax rate in fiscal year 2019 and future years. Securities and Exchange Commission (“SEC”) staff issued Staff Accounting Bulletin No. 118 (“SAB 118”) to provide guidance that companies should apply each reporting period related to the income tax effects of the 2017 Tax Act. SAB 118 provides that companies (i) should record the effects of the changes from the 2017 Tax Act for which the accounting is complete (not provisional), (ii) should record provisional amounts for the effects of the changes from the 2017 Tax Act for which the accounting is not complete, and for which reasonable estimates can be determined, in the period they are identified, and (iii) should not record provisional amounts if reasonable estimates cannot be made for the effects of the changes from the 2017 Tax Cut, and should continue to apply guidance based on the tax law in effect prior to the enactment on December 22, 2017. In addition, SAB 118 establishes a one-year measurement period (through December 22, 2018) where a provisional amount could be subject to adjustment, and requires certain qualitative and quantitative disclosures related to provisional amounts and accounting during the measurement period. The Company recorded a tax benefit of $22.6 million and a tax charge of $103.3 million for the three and nine months ended March 31, 2018 as compared to tax charges of $7.9 million and $18.0 million for the three and nine months ended March 31, 2017. The tax provision for the nine months ended March 31, 2018 reflects provisional charges under SAB 118 of $110.5 million for Repatriation Tax and $2.3 million for the remeasurement of deferred tax assets and liabilities to reflect the U.S. Federal statutory rate reductions in the Tax Act. These charges were partially offset by a tax benefit of $29.1 million related to excess tax benefits from stock-based compensation, of which $28.4 million was recorded in the three months ended March 31, 2018. The Company’s estimated fiscal year 2018 effective tax rate differs from the U.S. statutory rate primarily due to profits earned in jurisdictions where the tax rate is lower than the U.S. tax rate, excess tax benefit from stock-based compensation and the impact of the 2017 Tax Act. The U.S. Department of Treasury has issued guidance regarding the Repatriation Tax and we expect that they will issue additional guidance. Based on the information currently available, we can make a reasonable estimate of the Repatriation Tax and therefore recorded a provisional Repatriation Tax of $110.5 million, however, we are continuing to gather additional information and analyze the available authorities to more precisely compute the amount of the Repatriation Tax. As of March 31, 2018, the Company had approximately $28.6 million of unrecognized tax benefits, substantially all of which would, if recognized, affect its tax expense. The Company recorded a net increase of its unrecognized tax benefits of $0.9 million and $1.1 million, respectively, for the three and nine months ended March 31, 2018. The Company recognizes interest and penalties related to unrecognized tax benefits within the income tax expense line in the accompanying Consolidated Statement of Operations and Comprehensive Income. Accrued interest and penalties are included within the related tax liability line in the Consolidated Balance Sheet. As of March 31, 2018, the Company had $2.3 million accrued interest related to uncertain tax matters. The Company believes that it is reasonably possible that a decrease of up to $4 million in unrecognized tax benefits may occur due to settlements with tax authorities or statute lapse. On July 27, 2015, in Altera Corp. v. Commissioner, the U.S. Tax Court issued an opinion related to the treatment of stock-based compensation expense in an intercompany cost-sharing arrangement. On June 27, 2016, the Internal Revenue Service appealed the court's decision to the Ninth Circuit Court of Appeals. On November 10, 2016, the Internal Revenue Service filed its reply brief. We have reviewed this case and its potential impact on Ubiquiti and concluded that no adjustment to the consolidated financial statements is appropriate at this time. We will continue to monitor ongoing developments and potential impacts to our consolidated financial statements.
