With the Desktop version you can prepare and print unlimited federal and unlimited state returns and efile up to 5 federal for free (IRS limit). And it has what if scenarios and you can see and enter directly into the actual forms. State is currently $24.99 each to efile but it is free to print and mail unlimited returns.
