I have always done my own taxes, even when I owned a business. Personal taxes are a piece of cake.
The last 5 yrs or so, I've done them online. In Canada, the service is free of charge for those on disability, but even when I paid, "basic" filings were only something like $9.99 or $14.99 through a company called U-File. (I don't know if they are in the US though ...).
They walk you through an interview, just like H&R block, then apply your answers to the right places on the forms. Again, I don't know about the US, the government will correct anything you make a mistake on (to your advantage or disadvantage, whatever is applicable) because they get copies of all your employer/bank, etc. forms too.
