This response is correct - but it still begs the question. Why doesn't anyone advertise the free version of the software - specifically why doesn't the government advertise it? Also, I don't think that TurboTax would really need to pay more to advertise - they would just need to put an * on the ads they already have, with a "go here for a free version, offer based on income" - or some such thing. I'm guessing that TurboTax has probably considered doing this - for the good will it would generate - and then decided that the lost revenue from people not buying their most basic software package would not be worth it. And the lost revenue would probably be substantial.
