text: what if i recieved to much on federal tax returns? on my federal return i received 1000 more than what i was supposed to get according to the taxes i filed.  am i required to report anything. it depends on the situation.  do you have any dependents under the age of 17?  if so, did you take the child tax credit on your return?  $1000.00 is the amount available for the child tax credit.  in any case, if you made a mistake on your original return, they will send you a letter explaining the changes soon after your direct deposit.  if you do not receive this letter withing 2 weeks of the refund (or if you want top verify right away), call the help line at 1-800-829-1040, monday through friday from 7:00am - 10:00pm.  let them know that you received more than you expected and they will check you account for you and give you any information you need.  have: your ssn, exact refund amount and filing status handy.  good luck.
