<prompt> Human: We used a CPA for our taxes in 2016. It was the first time that we had used a CPA because our taxes had gotten a little more complicated, and thought it would be easy to turn it over and let someone handle it.He gave us an itemized sheet of documents to give him and we filled a checklist of docs that we had and gave him the documents. One was a 1099 from our financial advisor for all the dividends and capital gains that we made that year. Fast forward to today and we got an audit tax due notice from the IRS stating that we owe for not putting those capital gains on our return.Now it is our diligence to double check and we do owe the money, but is the CPA responsible for the interest that accrued over the last couple of years? Or our we completely at fault and the only thing the CPA loses is our future business?Edit: Thanks everyone for the replies. Ive contacted the CPA and showed the email that we sent him with the documents and the checklist. He has not responded which is typical behavior from him. We always knew we were not his top priority. Ill not contest it, pay it and move on. Ill be shopping for a new CPA. Edit 2: I thought I would update again. Still no response from the CPA. I think he knows he stepped in it and just decided to not act. I went ahead and responded to the notice and will pay. Choose your CPAs wisely.  <response>: Solo CPA practitioner here. Ask your CPA. If I made an error like missing reporting something that my client had given me, I would pay the penalties and interest myself.We all make mistakes, but we should also own up to our errors and make the client whole.
