<prompt> Human: Not sure there is anything that can be done but could use some advice. On my return my cpa put that I had paid in quarterly taxes, which I didnt. I have no idea where she even came up with the figure she used. I just got a letter from the irs stating that they adjusted my return and hit me with fines, interest etc for under paying 2015 taxes. So not only do I need to pay 8k more in taxes they tacked on 1400 on top of that. I know if I owe the tax amount there isnt anything I can do about that. I also know that once I signed the return I was basically agreeing to it and it comes back to me to make sure its accurate. However I cant help but feel like Im getting screwed. Planning on calling the cpa tomorrow but Im so mad i cant think straight. Im at a loss on how she came up with that when we discussed that i hadnt paid in quarterly and no information was provided that would show that. What questions should I be asking the cpa? Should the firm pay my 1400 in penalties because of their error? Any suggestions would be appreciated. UPDATE: I still have not spoken with the CPA yet. A post it note was found in our paperwork, I assume written by the CPA stating that per our interview I told her estimated 2015 taxes were paid. The picture is becoming more clear. Does that really change anything though? Final update: I spoke with the firm owner. He is working on getting the IRS to waive the fees and interest and said if he cant he would pay those for me.  <response>: What questions should I be asking the cpa? How did you arrive at the figure on Line 65Consider requesting a First Time Abatement FTA of the Failure To File and or Failure To Pay penalties. Assuming you have a good history of compliance filed and paid timely for tax years 2012 - 2014, the request is generally allowed for any dollar amount. Interest cant be abated for FTA criteria or Reasonable Cause, but the interest would be reduced if the penalties are abated. Ask your CPA about their Errors and Omissions policies, and check the contract you signed when you engaged their tax services.
