In 1991, Microsoft decided to produce a competitor to Quicken called Microsoft Money. The first version of Quicken was coded in Microsoft's BASIC programming language for the IBM PC and UCSD Pascal for the Apple II by Tom Proulx and had to contend with a dozen serious competitors. The two started Intuit, which initially operated out of a modest room on University Avenue in Palo Alto. On his quest to find a programmer he ended up running into Tom Proulx at Stanford. Intuit was conceived by Scott Cook, whose prior work at Procter & Gamble helped him realize that personal computers would lend themselves towards replacements for paper-and-pencil based personal accounting. The company was founded in 1983 by Scott Cook and Tom Proulx in Palo Alto, California. Intuit has lobbied extensively against the IRS providing taxpayers with free pre-filled forms, as is the norm in developed countries. As of the 2021 tax filing season, TurboTax no longer participates in the Free File Alliance. In 2019, investigations by ProPublica found that Intuit deliberately steered taxpayers from the free TurboTax Free File to the paid TurboTax Free Edition using tactics including search engine delisting and a deceptive discount targeted to members of the military. Intuit offered a free online service called TurboTax Free File as well as a similarly named service called TurboTax Free Edition which is not free for most users.

As of 2019, more than 95% of its revenues and earnings come from its activities within the United States. Intuit's products include the tax preparation application TurboTax, personal finance app Mint, the small business accounting program QuickBooks, the credit monitoring service Credit Karma, and email marketing platform Mailchimp. The company is headquartered in Mountain View, California, and the CEO is Sasan Goodarzi. is an American business software company that specializes in financial software.
