Income Tax Disclosure [Abstract]
Income Tax Disclosure [Text Block]	Income Taxes Our income tax benefit was $93,795 and $87,680 for the three and six months ended December 31, 2019, respectively, compared to an expense of $14,399 and $19,880 for the three and six months ended December 31, 2018. During the three months ended December 31, 2019, we recognized a discrete deferred tax benefit of $114,114 related to Swiss Tax Reform, as discussed below. Without this benefit, tax expense would have increased, primarily attributable to increased pre-tax income for the three and six months ended December 31, 2019 as compared to the same prior year periods. In addition, during the three months ended December 31, 2018 we recognized "Patent Box" tax benefits of $3,547 granted to our Pixartprinting business in Italy. Also, during the six months ended December 31, 2018, we recognized a decrease in deferred tax assets of $5,574 related to 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. Excluding the effect of discrete tax adjustments, our estimated annual effective tax rate is higher for fiscal 2020 as compared to fiscal 2019 primarily due to tax impacts of changing Cimpress N.V.'s tax residency from the Netherlands to Ireland in February 2019, offset by an expectation of a more favorable geographical mix of consolidated earnings. 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. 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 December 31, 2019, we had unrecognized tax benefits of $5,533, including accrued interest and penalties of $587. 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 $400 to $800 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 2016 through 2019 remain open for examination by the IRS and the years 2013 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.
