Income Tax Disclosure [Abstract]
Income Taxes	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 March 31, 2021 and June 30, 2020, the Company maintained a total valuation allowance of $15,006 and $14,582, 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. This also includes a valuation allowance in the amount of $580 related to foreign tax credit carryforward that is not expected to be utilized in the future. 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 those related to the change in U.S. tax law as well as other adjustments to accruals for tax uncertainties, are recognized in the quarter in which the related event occurs. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was signed into law. The CARES Act contains significant business tax provisions, including modifications to the rules limiting the deductibility of net operating losses (NOLs), expensing of qualified improvement property (QIP) and business interest in Internal Revenue Code Sections 172(a) and 163(j), respectively. The effects of the new legislation are recognized upon enactment. The Company did not recognize any significant impact to income tax expense for the nine months ended March 31, 2021 relating to the CARES Act. For the three months ended March 31, 2021 and 2020, the Company's effective tax rate was 23.7% and 22.6%, respectively. For the nine months ended March 31, 2021 and 2020, the Company's effective tax rate was 23.0% and 22.5%, respectively. For the three and nine months ended March 31, 2021 and 2020, the Company's effective tax rate exceeded the statutory federal income tax rate of 21% primarily due to the impact of U.S. state taxes. This increase in tax rate in both periods was partially offset by a windfall benefit generated by certain stock based compensation, and benefits from the foreign derived intangible income deduction, the research and development tax credit, and the impact of non-controlling interests in the LLC.
