Income Taxes	9 Months Ended
Income Taxes	Mar. 31, 2020
Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes We have calculated our year-to-date income tax on ordinary income based on the actual year-to-date effective tax rate rather than the estimated annual tax rate for the nine months ended March 31, 2020. We determined that the annual estimated effective tax rate would not provide a reliable estimate as small changes in the estimated annual income would result in significant changes in the estimated annual tax rate. Our income tax expense was $1,039 for the three months ended March 31, 2020 and a tax benefit of $86,641 for the nine months ended March 31, 2020, compared to expense of $4,091 and $23,971 for the three and nine months ended March 31, 2019. The decreased tax expense for the three months ended March 31, 2020 was primarily due to a lower actual effective tax rate for the nine months ended March 31, 2020, excluding goodwill impairments with no tax benefit and the deferred tax benefit related to Swiss Tax Reform of $114,114 discussed below, as compared to the estimated annual effective tax rate for the same prior year period. Without this benefit, tax expense would have increased for the nine months ended March 31, 2020 as compared to the same prior year period, primarily attributable to increased pre-tax income, excluding goodwill impairments with no tax benefit. The decrease in effective tax rate year-over-year was primarily due to a more favorable mix of earnings, offset by tax impacts of changing Cimpress N.V.'s tax residency from the Netherlands to Ireland in February 2019. Our effective tax rate continues to be negatively impacted by losses in certain jurisdictions where we are unable to recognize a tax benefit in the current period. During the three months ended March 31, 2020, we recognized tax expense of $28,465 to record a full valuation allowance against our U.S. deferred tax assets. The change in judgment to no longer recognize the deferred tax assets was driven by decreased profits due to impacts of the COVID-19 pandemic and goodwill impairments. Also during the three months ended March 31, 2020, we recognized tax benefits of $15,350 related to excess tax benefits from share based compensation and $10,894 for the re-measurement of U.S. tax losses that will be carried back to tax years with higher U.S. federal tax rates under the U.S. Coronavirus Aid, Relief, and Economic Security Act, enacted March 27, 2020. In addition, during the nine months ended March 31, 2019, we recognized "Patent Box" tax benefits of $3,547 granted to our Pixartprinting business in Italy and tax expense of $5,574 related to a decrease in deferred tax assets under Notice 2018-68 issued by the United States Internal Revenue Service, which provided guidance regarding amendments to Section 162(m) of the Internal Revenue Code contained in the Tax Cuts and Jobs Act. On October 25, 2019, the canton of Zurich enacted tax law changes by publishing the results of its referendum to adopt the Federal Act on Tax Reform and AHV Financing (TRAF), which we refer to as Swiss Tax Reform. Swiss Tax Reform is effective as of January 1, 2020 and includes the abolishment of various favorable federal and cantonal tax regimes. Swiss Tax Reform provides transitional relief measures for companies that are losing the tax benefit of a ruling, including a "step-up" for amortizable goodwill, equal to the amount of future tax benefit they would have received under their existing ruling, subject to certain limitations. We recognized a tax benefit of $114,114 to establish new Swiss deferred tax assets related to transitional relief measures and remeasuring our existing Swiss deferred tax assets and liabilities. We don't expect to realize the majority of this benefit until fiscal 2025 through fiscal 2030. As of March 31, 2020, we had unrecognized tax benefits of $5,909, including accrued interest and penalties of $336. We recognize interest and, if applicable, penalties related to unrecognized tax benefits in the provision for income taxes. If recognized, the entire amount of unrecognized tax benefits would reduce our tax expense. It is reasonably possible that a reduction in unrecognized tax benefits may occur within the next twelve months in the range of $70 to $400 related to the lapse of applicable statutes of limitations. We conduct business in a number of tax jurisdictions and, as such, are required to file income tax returns in multiple jurisdictions globally. The years 2014 through 2019 remain open for examination by the IRS and the years 2014 through 2019 remain open for examination in the various states and non-US tax jurisdictions in which we file tax returns. We believe that our income tax reserves are adequately maintained taking into consideration both the technical merits of our tax return positions and ongoing developments in our income tax audits. However, the final determination of our tax return positions, if audited, is uncertain, and there is a possibility that final resolution of these matters could have a material impact on our results of operations or cash flows.
