The phone-tax refund?  Take advantage of this one-time refund.  It's line 71 on the 1040 this year.

You can figure your refund based on how much you actually paid, if you have old phone bills.   Or, you can opt for the standard refund. That amounts to $30 for an individual, $40 for two-person household, $50 for three and $60 for families of four or more.
