The IRS has actually run trials like this in the past. Very successful, at least for simply W2-based returns, since most people's taxable transactions get reported by companies anyway (i.e., mortgages/interest, other income, etc.) and most people use the standardized deduction. Inuit and Quicken subsequently lobbied to end those programs and even bar the IRS from running similar programs...
Fun fact. Intuit spent just $2.4 million on lobbying per year and $775,000 on campaign contributions: https://www.opensecrets.org/orgs/summary.php?id=D000026667&c... . If their lobbying dollars are what caused the IRS to stop those programs, you could "outbid" them with just a Kickstarter. Intuit and friends are a red herring: https://www.huffingtonpost.com/grover-norquist/grover-norqui...
