Description of Business and Summary of Significant Accounting Policies [Abstract]
Description of Business	Description of Business Intuit Inc. provides business and financial management solutions for small and medium-sized businesses, consumers, accounting professionals and financial institutions. Our flagship products and services, including QuickBooks, Quicken and TurboTax, simplify small business management and payroll processing, personal finance, and tax preparation and filing. ProSeries and Lacerte are Intuit’s tax preparation offerings for professional accountants. Our Financial Services business provides online banking solutions and services to banks and credit unions. Incorporated in 1984 and headquartered in Mountain View, California, we sell our products and services primarily in the United States.
Basis of Presentation	Basis of Presentation These condensed consolidated financial statements include the financial statements of Intuit and its wholly owned subsidiaries. We have eliminated all significant intercompany balances and transactions in consolidation. In November 2009 we acquired Mint Software Inc. for total consideration of approximately $170 million and in May 2010 we acquired Medfusion, Inc. for total consideration of approximately $89 million. We have included the results of operations for Mint and Medfusion in our consolidated results of operations from their respective dates of acquisition. In January 2010 we sold our Intuit Real Estate Solutions (IRES) business. We have reclassified our financial statements for all periods prior to the sale to reflect IRES as discontinued operations. Unless noted otherwise, discussions in these notes pertain to our continuing operations. We have included all adjustments, consisting only of normal recurring items and the reclassifications for discontinued operations discussed above, which we considered necessary for a fair presentation of our financial results for the interim periods presented. These unaudited condensed consolidated financial statements and accompanying notes should be read together with the audited consolidated financial statements in Item 8 of our Annual Report on Form 10-K for the fiscal year ended July 31, 2010. Results for the nine months ended April 30, 2011 do not necessarily indicate the results we expect for the fiscal year ending July 31, 2011 or any other future period. We have reclassified certain amounts previously reported in our financial statements to conform to the current presentation, including amounts related to reportable segments and discontinued operations.
Seasonality	Seasonality Our QuickBooks, Consumer Tax and Accounting Professionals businesses are highly seasonal. Revenue from our QuickBooks software products tends to be highest during our second and third fiscal quarters. Sales of income tax preparation products and services are heavily concentrated in the period from November through April. Seasonal patterns mean that our total net revenue is usually highest during our second quarter ending January 31 and third quarter ending April 30. We typically report losses in our first quarter ending October 31 and fourth quarter ending July 31, when revenue from our tax businesses is minimal while operating expenses continue at relatively consistent levels.
Significant Accounting Policies	Significant Accounting Policies We describe our significant accounting policies in Note 1 to the financial statements in Item 8 of our Annual Report on Form 10-K for the fiscal year ended July 31, 2010. As discussed below, on August 1, 2010 we adopted authoritative guidance on multiple-deliverable revenue arrangements. There have been no other changes to our significant accounting policies during the first nine months of fiscal 2011.
Multiple-Deliverable Revenue Arrangements	Multiple-Deliverable Revenue Arrangements In October 2009 the Financial Accounting Standards Board (FASB) amended the accounting standards applicable to revenue recognition for multiple-deliverable revenue arrangements that are outside the scope of industry-specific software revenue recognition guidance. This new guidance amends the criteria for allocating consideration in multiple-deliverable revenue arrangements by establishing a selling price hierarchy. The selling price used for each deliverable will be based on vendor-specific objective evidence (VSOE) if available, third-party evidence (TPE) if VSOE is not available, or estimated selling price (ESP) if neither VSOE nor TPE is available. The guidance also eliminates the use of the residual method of allocation and requires that arrangement consideration be allocated at the inception of the arrangement to all deliverables using the relative selling price method. We adopted this guidance on a prospective basis on August 1, 2010, and therefore applied it to relevant revenue arrangements originating or materially modified on or after that date. VSOE generally exists when we sell the deliverable separately and we are normally able to establish VSOE for all deliverables in these multiple-element arrangements; however, in certain limited instances VSOE cannot be established. This may be because we infrequently sell each element separately, do not price products within a narrow range, or have a limited sales history, such as in the case of our emerging market offerings. When VSOE cannot be established, we attempt to establish selling price for each element based on TPE. TPE is determined based on competitor prices for similar deliverables when sold separately. When we are unable to establish selling price using VSOE or TPE, we use ESP in our allocation of arrangement consideration. We determine ESP for a product or service by considering multiple factors, including, but not limited to, geographies, market conditions, competitive landscape, internal costs, gross margin objectives, and pricing practices. Our adoption of this new accounting guidance did not have a significant impact on the timing and pattern of revenue recognition when applied to multiple-element arrangements because our multiple-element offerings are predominantly software or software-related and VSOE exists for most of these offerings.
Computation of Net Income (Loss) Per Share	Computation of Net Income (Loss) Per Share We compute basic net income or loss per share using the weighted average number of common shares outstanding during the period. We compute diluted net income per share using the weighted average number of common shares and dilutive potential common shares outstanding during the period. Dilutive potential common shares include shares issuable upon the exercise of stock options and upon the vesting of restricted stock units (RSUs) under the treasury stock method. We include stock options with combined exercise prices, unrecognized compensation expense and tax benefits that are less than the average market price for our common stock, and RSUs with unrecognized compensation expense and tax benefits that are less than the average market price for our common stock, in the calculation of diluted net income per share. We exclude stock options with combined exercise prices, unrecognized compensation expense and tax benefits that are greater than the average market price for our common stock, and RSUs with unrecognized compensation expense and tax benefits that are greater than the average market price for our common stock, from the calculation of diluted net income per share because their effect is anti-dilutive. Under the treasury stock method, the amount that must be paid to exercise stock options, the amount of compensation expense for future service that we have not yet recognized for stock options and RSUs, and the amount of tax benefits that will be recorded in additional paid-in capital when the awards become deductible are assumed to be used to repurchase shares. In loss periods, basic net loss per share and diluted net loss per share are the same since the effect of potential common shares is anti-dilutive and therefore excluded.
Concentration of Credit Risk and Significant Customers	Concentration of Credit Risk and Significant Customers No customer accounted for 10% or more of total net revenue in the three or nine months ended April 30, 2011 or April 30, 2010. No customer accounted for 10% or more of total accounts receivable at April 30, 2011 or July 31, 2010.
Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU 2011-04, “Fair Value Measurement (Topic 820)” On May 12, 2011 the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2011-04, “Fair Value Measurement (Topic 820): Amendments to Achieve Common Fair Value Measurement and Disclosure Requirements in U.S. GAAP and IFRSs” (ASU 2011-04). This update amends Accounting Standards Codification (ASC) Topic 820, “Fair Value Measurement and Disclosure.” ASU 2011-04 clarifies the application of certain existing fair value measurement guidance and expands the disclosures for fair value measurements that are estimated using significant unobservable (Level 3) inputs. ASU 2011-04 is effective for annual and interim reporting periods beginning on or after December 15, 2011, which means that it will be effective for our fiscal quarter beginning February 1, 2012. The new guidance is to be adopted prospectively and early adoption is not permitted. We do not believe that adoption of ASU 2011-04 will have a significant impact on our financial position, results of operations or cash flows.

Disclosure of accounting policy for computing basic and diluted earnings or loss per share for each class of common stock and participating security. Addresses all significant policy factors, including any antidilutive items that have been excluded from the computation and takes into account stock dividends, splits and reverse splits that occur after the balance sheet date of the latest reporting period but before the issuance of the financial statements.

- Definition

Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed. If a sales transaction has multiple element arrangements (for example, delivery of multiple products, services or the rights to use assets) the disclosure may indicate the accounting policy for each unit of accounting as well as how units of accounting are determined and valued. The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction.
