What do I do if I double-reported income on my tax return?

Subject: double reported income

I just realized that my employer has been reporting my ordinary income from disqualifying sales of ISO shares on my W-2 for past years. Not realizing this, I also reported the sales from Form 1099B into Turbo Tax. The software didn’t ask whether the proceeds were included in W-2 wages. As a result, I have double reported the income.
I know other people who have made the same error.
What should we do?

You should file amended income tax returns to recover the overpaid tax.
The federal form is Form 1040X.
Assuming you filed by April 15, 2005, your deadline for an amended 2004 income tax return is April 15, 2008.
We do this all the time. It’s a common error.
