Income Tax Disclosure [Abstract]
Income Tax	Income Taxes Malibu Boats, Inc. is taxed as a C corporation for U.S. income tax purposes and is therefore subject to both federal and state taxation at a corporate level. The LLC continues to operate in the United States as a partnership for U.S. federal income tax purposes. Income taxes are computed in accordance with ASC Topic 740, Income Taxes, and reflect the net tax effects of temporary differences between the financial reporting carrying amounts of assets and liabilities and the corresponding income tax amounts. The Company has deferred tax assets and liabilities and maintains valuation allowances where it is more likely than not that all or a portion of deferred tax assets will not be realized. To the extent the Company determines that it will not realize the benefit of some or all of its deferred tax assets, such deferred tax assets will be adjusted through the Company’s provision for income taxes in the period in which this determination is made. As of September 30, 2017 and June 30, 2017, the Company maintained a valuation allowance of $10,345 and $10,324, respectively, against deferred tax assets related to state net operating losses and future amortization deductions (with respect to the Section 754 election) that are reported in the Tennessee corporate tax return without offsetting income, which is taxable at the LLC. The increase in the valuation allowance is due to the exchanges of LLC Units into Class A common stock by certain LLC Unit holders during the three months ended September 30, 2017. The Company’s consolidated interim effective tax rate is based upon expected annual income from operations, statutory tax rates and tax laws in the various jurisdictions in which the Company operates. Significant or unusual items, including adjustments to accruals for tax uncertainties, are recognized in the quarter in which the related event occurs. For the three months ended September 30, 2017 and 2016, the Company's effective tax rate was (4.2)% and 33.7%, respectively. For the three months ended September 30, 2017, the principal differences in the Company's effective tax rate with comparable historical periods presented and the statutory federal income tax rate of 35% relate to the impact of the Cobalt acquisition on the state tax rate used to measure deferred taxes. Additionally, the Company's effective tax rate for the three months ended September 30, 2017 and 2016, is related to the impact of the non-controlling interests in the LLC, a pass-through entity for U.S. federal tax purposes, state income taxes attributable to the LLC, and the benefit of deductions under Section 199 of the Internal Revenue Code.
