Tax preparation companies have spent over $90 million lobbying against a free tax-filing system in the US. The companies, including Intuit and H&R Block, have been accused of using 'revolving door' lobbyists to influence policy decisions. Despite this, the IRS is moving forward with a pilot program to offer free direct filing services. The program aims to simplify tax filing for most taxpayers, who already have their necessary information on file with the government.
