<prompt> Human: Im a grad student who gets a 30,000 per year research stipend from an NSF IGERT grant.My university which pays me some money to make my take home pay even with my peers with other funding sources.I received a letter from the IRS saying I owe 3300 in back taxes from 2012 when I thought I had already filed and paid these taxes. After going over my documentation, it seems the issue probably stems from my IGERT stipend. I was never given any documentation of the 30,000 payment for 2012. Instead, to be honest, I self reported this 30,000 income as other income. I have a W-2 from my university for that year, but it says I only made about 2,000 the difference between the IGERT stipend and what my university promised me Id make.It would seem that now the IRS has some documentation of the IGERT stipend though I did not receive any for the past 3 years and is adding this 30,000 on to my already reported 30,000 of other income so the IRS incorrectly thinks I made 62,000I checked my records and I paid the correct amount for the 32,000 I made for 2012. Am I on the hook for 62,000 even though the 30,000 seems to be double reported?Tl;dr I reported a stipend as other income because I didnt have any documentation. IRS found documentation and double counted this money.  <response>: Sounds like a computer generated letter. Call them and it will probably be solvable over the phone. Warning: the call might take a while, so schedule some time to deal with this.
