>> Let the IRS do it, they send you a copy and you send it back either as is or with modifications.
That's why you check it.
And to respond to a possible next question, do we trust TurboTax (or others) more?
> Also, if you have other income with no W2 it needs to be reported.
All those other forms that are handed to you are ALSO already handed to the IRS. For example the 1099. The W2 was an easily verifiable example of how they already have this information before you receive it. The gov already has copies of all those forms. So really as tax payers we're paying for the IRS to do our taxes and we're paying for companies like TurboTax to do it as well (assuming you don't do it yourself)
What I don't understand is why we can't have the IRS running their own tax prep website. The government seems to be capable of running other websites just fine.
