I was blown away when I learned one of my wife's friends, who has a single W2 and some bank interest, pays H&R Block every year to file her taxes! No stocks or rental income or IRAs or anything else that could complicate things. But still she, and millions of Americans, pay these companies to fill out what amounts to a single form. Eye opening.

Entering a 1099-B for stocks is dead simple, you enter in a few numbers (cumulative buys, sells, and wash sales) and you’re done. You transmit your trade history to the IRS digitally.

It takes me about 20-30 minutes to enter a W2, 1099-INT, 1099-B, 1099-B (futures) and a 1256 (straddles and index options) into FreeTaxUSA every spring.

Just like every other company, HR block sells emotions, not a product. The two emotions are: not getting in trouble with the IRS, and getting a good deal (with whatever advantage the HR block employee can find applies to you). Maybe also not having the stress of having to learn how to do your taxes. (WTF is an AMT?)
