I find TurboTax to be better than H&R Block for filing taxes online. It's only barely less user-friendly, but it asks better questions and always gives me the best results. H&R Block refused to let me file as Head of Household and therefore had me owing money. TurboTax gave me a bit over $300 -- barely enough to buy a single taco at Taco Bell these days. But I'll take it!
