Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION – The consolidated balance sheets as of January 31, 2017 and 2016, the consolidated statements of operations and comprehensive loss for the three and nine months ended January 31, 2017 and 2016, and the consolidated statements of cash flows for the nine months ended January 31, 2017 and 2016 have been prepared by the Company, without audit. In the opinion of management, all adjustments, which include only normal recurring adjustments, necessary to present fairly the financial position, results of operations and cash flows as of January 31, 2017 and 2016 and for all periods presented have been made. "H&R Block," "the Company," "we," "our" and "us" are used interchangeably to refer to H&R Block, Inc. or to H&R Block, Inc. and its subsidiaries, as appropriate to the context. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (GAAP) have been condensed or omitted. These consolidated financial statements should be read in conjunction with the financial statements and notes thereto included in our April 30, 2016 Annual Report to Shareholders on Form 10-K. All amounts presented herein as of April 30, 2016 or for the year then ended are derived from our April 30, 2016 Annual Report to Shareholders on Form 10-K. MANAGEMENT ESTIMATES – The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Significant estimates, assumptions and judgments are applied in the evaluation of contingent losses arising from our discontinued mortgage business, contingent losses associated with pending claims and litigation, valuation allowances on deferred tax assets, reserves for uncertain tax positions and related matters. Estimates have been prepared based on the best information available as of each balance sheet date. As such, actual results could differ materially from those estimates. SEASONALITY OF BUSINESS – Our operating revenues are seasonal in nature with peak revenues typically occurring in the months of January through April. Therefore, results for interim periods are not indicative of results to be expected for the full year. DISCONTINUED OPERATIONS – Our discontinued operations include the results of operations of Sand Canyon Corporation, previously known as Option One Mortgage Corporation (including its subsidiaries, collectively, SCC), which exited its mortgage business in fiscal year 2008. See notes 10 and 11 for additional information on litigation, claims and other loss contingencies related to our discontinued operations. NEW ACCOUNTING PRONOUNCEMENTS – In April 2015, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2015-3, "Interest - Imputation of Interest," (ASU 2015-3) which requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. This guidance must be applied retrospectively to all periods presented. We adopted this guidance effective May 1, 2016. Prior periods have been retrospectively adjusted to conform to the current period presentation. Debt issuance costs related to our Senior Notes previously reported as other current assets and other noncurrent assets have been reclassified to long-term debt. This guidance did not have a material effect on our consolidated financial statements.
