This statement is false. If you look at Open Secrets, $16,000 lines up exactly with what H&R Block and Intuit employees donated to Neal in 2016 and 2018. H&R Block and Intuit have tens of thousands of employees--it's not surprising that many donated to a Democrat with a high-ranking committee position.
Fun fact: By the article's parlance "Google" gave more to Neal in 2018 than Intuit. Gasp--Google must be in on the tax filing scam too!
