Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	NOTE 1: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES BASIS OF PRESENTATION – The consolidated balance sheets as of October 31, 2018 and 2017, the consolidated statements of operations and comprehensive loss for the three and six months ended October 31, 2018 and 2017, and the consolidated statements of cash flows for the six months ended October 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 October 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, 2018 Annual Report to Shareholders on Form 10-K and the additional financial statement disclosures provided under Accounting Standards Update No. 2014-09, “Revenue from Contracts with Customers” (ASU 2014-09), included in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on November 15, 2018. All amounts presented herein as of April 30, 2018 or for the year then ended are derived from our April 30, 2018 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 – Revenue Recognition. In May 2014, the FASB issued 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 replaced most existing revenue recognition guidance in GAAP when it became effective. The new standard was effective for us on May 1, 2018, and we adopted using the full retrospective transition method. The adoption of this guidance did not have a significant impact on our consolidated financial statements. See note 2 for additional information. 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. This guidance was effective for us on May 1, 2018 and we adopted using the modified retrospective transition method. We recognized a $101.0 million cumulative effect adjustment to increase the opening balance of retained earnings and increase deferred tax assets resulting from intra-entity transfers of intellectual property in fiscal year 2018. Leases. In February 2016, the FASB issued Accounting Standards Update No. 2016-02, "Leases" (ASU 2016-02), which will require the recognition of lease assets and lease liabilities by lessees for leases previously classified as operating leases. ASU 2016-02 also requires additional qualitative and quantitative disclosures related to the nature, timing and uncertainty of cash flows arising from leases. This guidance will be effective for us on May 1, 2019, with early adoption permitted. In July 2018, the FASB approved an amendment to the new guidance that allows companies the option of using the effective date of the new standard as the initial application (at the beginning of the period in which is it adopted, rather than at the beginning of the earliest comparative period). We expect to adopt ASU 2016-02 prospectively, and we are currently evaluating the impact of ASU 2016-02 on our consolidated financial statements. However, we expect the impact of this guidance on our consolidated financial statements could be significant, as our future minimum operating lease commitments totaled $820.9 million as of April 30, 2018. We also expect that adoption of the new standard will require changes to our internal controls over financial reporting.
