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, 2018 and 2017, the consolidated statements of operations and comprehensive loss for the three and nine months ended January 31, 2018 and 2017, and the consolidated statements of cash flows for the nine months ended January 31, 2018 and 2017 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, 2018 and 2017 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, 2017 Annual Report to Shareholders on Form 10-K. All amounts presented herein as of April 30, 2017 or for the year then ended are derived from our April 30, 2017 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, reserves for uncertain tax positions, the impact of legislation commonly referred to as the Tax Cuts and Jobs Act (Tax Legislation), 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. See note 7 for additional discussion of the impact of the Tax Legislation. SEASONALITY OF BUSINESS – Our operating revenues are seasonal in nature with peak revenues typically occurring in the months of February 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 9 and 10 for additional information on litigation, claims, and other loss contingencies related to our discontinued operations. NEW ACCOUNTING PRONOUNCEMENTS – Restricted Cash in Statement of Cash Flows. In November 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update No. 2016-18, "Restricted Cash (a consensus of the FASB Emerging Issues Task Force)," (ASU 2016-18). This guidance requires that restricted cash be included with cash and cash equivalents when reconciling the beginning and end-of-period total amounts shown on the statement of cash flows. This guidance must be applied retrospectively to all periods presented. We adopted ASU 2016-18 effective May 1, 2017. All prior periods have been adjusted to conform to the current period presentation, which resulted in an increase in cash used in operations of $33.9 million for the nine months ended January 31, 2017. Stock-Based Compensation. In March 2016, the FASB issued Accounting Standards Update No. 2016-09, "Improvements to Employee Share-Based Payment Accounting," (ASU 2016-09). This guidance requires that, among other things: (1) all excess tax benefits and tax deficiencies would be recognized as income tax expense or benefit in the income statement; and (2) excess tax benefits would not be separated from other income tax cash flows and, thus, would be classified along with other cash flows as an operating activity. The transition requirements for this guidance varies by component, but the changes applicable to us were applied prospectively. We adopted ASU 2016-09 effective May 1, 2017. We recorded a discrete tax benefit of $4.6 million related to stock-based compensation during the nine months ended January 31, 2018. Revenue Recognition. In May 2014, the FASB issued Accounting Standards Update No. 2014-09, "Revenue from Contracts with Customers," (ASU 2014-09) which is a comprehensive new revenue recognition model that requires an entity to recognize the amount of revenue which reflects the consideration it expects to receive in exchange for the transfer of the promised goods or services to customers. This ASU also requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract, and clarifies guidance for multiple-element arrangements. This guidance will replace most existing revenue recognition guidance in GAAP when it becomes effective. The new standard is effective for us on May 1, 2018. The standard permits the use of either the full retrospective or modified retrospective transition method. We have substantially completed our evaluation of the impact of ASU 2014-09 on our United States (U.S.) assisted tax preparation fees, U.S. royalties, U.S. DIY tax preparation fees, revenues from Peace of Mind® Extended Service Plan (POM), revenues from Refund Transfers (RTs), revenues from H&R Block Emerald Prepaid MasterCard® (Emerald Card), interest and fee income from H&R Block Emerald Advance® lines of credit (EAs) and fees from Tax Identity Shield® and based on the preliminary results of our evaluation, we do not expect the application of this guidance to have a material impact on the recognition of revenue related to these services. Changes to our client agreements or service design before adoption of the new standard could change our preliminary conclusions. We are still evaluating the impact of this guidance as it relates to other revenue streams, as well as certain associated expenses. Depending on the results of our review, there could be changes to the classification and timing of recognition of revenues and expenses related to other revenue streams. We currently expect to adopt using the full retrospective transition method, under which we will recast prior periods to comply with this new guidance. We are continuing our assessment, including evaluating the standard's impact on our internal controls. Income Taxes. In October 2016, the FASB issued Accounting Standards Update No. 2016-16, "Income Taxes (Topic 740): Intra-Entity Asset Transfers of Assets Other than Inventory," (ASU 2016-16). The new guidance eliminates the exception for intra-entity transfers other than inventory and requires the recognition of current and deferred income taxes resulting from such a transfer when the transfer occurs. We will adopt this guidance on May 1, 2018 on a modified retrospective basis. We estimate that we will recognize a cumulative-effect adjustment to retained earnings between $95 million and $110 million, which will also result in increases in deferred tax assets and income tax reserves. However, future transactions and law changes prior to adoption could significantly change the impact of adoption.
