Well, that kind of defeats the potential labor savings of using a computer.I've already got spreadsheets which list my deductions, total them, perform basic calculations, etc. and I can transfer those into the pdf forms. What the IRS should do, if they weren't mired in the 19th century, is put out xls files with the forms on them, and enter calculations into the cells that use them. For example, where it says "multiply line 4a by 0.15", there would be a protected cell with that formula already in it. Every year the IRS would update these spreadsheets. As it is now, I have to incorporate any changes in the forms myself.Also, there is a convenience factor in having a program do your state return for you, and figure out the arcane AMT.
