Accounting Policies [Abstract]
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. We have included all adjustments, consisting only of normal recurring items, which we considered necessary for a fair presentation of our financial results for the interim periods presented. We have reclassified certain amounts previously reported in our financial statements to conform to the current presentation, including amounts related to discontinued operations and reportable segments. See Note 4, “Discontinued Operations,” and Note 10, “Segment Information,” for more information. As discussed in Note 4, we sold our Intuit Websites business in September 2012. In August 2013 we sold our Intuit Financial Services (IFS) business and our Intuit Health business. We have reclassified our statements of operations for all periods presented to reflect these three businesses as discontinued operations. We have also segregated the net assets of IFS from continuing operations on our balance sheet at July 31, 2013. The net assets of Intuit Websites and Intuit Health were not significant, so we have not segregated them from continuing operations on our balance sheet at July 31, 2013. Because the cash flows of our Intuit Websites, IFS, and Intuit Health discontinued operations were not material for any period presented, we have not segregated the cash flows of those businesses from continuing operations on our statements of cash flows. Unless noted otherwise, discussions in these notes pertain to our continuing operations. 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, 2013. Results for the six months ended January 31, 2014 do not necessarily indicate the results we expect for the fiscal year ending July 31, 2014 or any other future period.
Seasonality	Seasonality Our QuickBooks, Consumer Tax, and Professional Tax offerings 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. These 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. During these quarters, revenue from our tax businesses is minimal while core operating expenses such as research and development continue at relatively consistent levels.
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.

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 determining an entity's fiscal year or other fiscal period. This disclosure may include identification of the fiscal period end-date, the length of the fiscal period, any reporting period lag between the entity and its subsidiaries, or equity investees. If a reporting lag exists, the closing date of the entity having a different period end is generally noted, along with an explanation of the necessity for using different closing dates. Any intervening events that materially affect the entity's financial position or results of operations are generally also disclosed.
