Income Tax Disclosure [Abstract]
Income Taxes	(11) Income Taxes On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (“the TCJA”) was signed into law, which enacted various changes to the U.S. corporate tax law. Some of the most significant provisions impacting corporations include a reduced U.S. corporate income tax rate from 35% to 21% effective in 2018, a one-time "deemed repatriation" tax on unremitted earnings accumulated in non-U.S. jurisdictions, limitation on deductibility of interest, the transition of U.S. international taxation from a worldwide tax system to a territorial tax system and other provisions. U.S. GAAP accounting for income taxes requires that Aceto record the impacts of any tax law change on the Company’s deferred income taxes in the quarter that the tax law change is enacted. Due to the complexities involved in accounting for the enactment of the TCJA, SEC Staff Accounting Bulletin (“SAB”) 118 allowed Aceto to provide a provisional estimate of the impacts of the TCJA in its earnings for the fiscal year ended June 30, 2018. Accordingly, based on the then currently available information, the Company recorded additional income tax expense of $13,739 for the year ended June 30, 2018. The charge was comprised of $5,075 related to the remeasurement of Aceto’s deferred tax assets arising from a lower U.S. corporate tax rate, $6,219 related to the deemed repatriation of unremitted earnings of foreign subsidiaries (the “transition tax”) and $2,445 related to deferred tax liabilities for local tax authorities as the Company no longer asserts permanent reinvestment of its undistributed non-U.S. subsidiaries' earnings. The Company finalized the calculations of the transition tax liability in the quarter ended December 31, 2018, with a reduction to the amount previously recorded of $405.
