[Maker of the tax software] Intuit has spent about $11.5 million on federal lobbying in the past five years — more than Apple or Amazon. Although the lobbying spans a range of issues, Intuit’s disclosures pointedly note that the company “opposes IRS government tax preparation.” … Roughly 25 million Americans used TurboTax last year, and a recent GAO analysis said the software accounted for more than half of individual returns filed electronically. TurboTax products and services made up 35 percent of Intuit’s $4.2 billion in total revenues last year.
