I'm representing the client; I prepared their returns and they called me in a panic when they received the notice.
Apparently, I'm not as stupid as I think I am. I had someone review the returns and they didn't find any errors. They're confident that I took the losses the client was entitled to. They reviewed my basis calculations and all looks fine. And the colleague doesn't see where amendments need to be filed.
This is my first ever audit and I'm a bit nervous and was losing sleep over this and reading horror stories on the internet and second guessing everything I did, but all my numbers have backup and are defendable.
The IRS auditor went to visit the client this week and he was impressed that they have adequate procedures in place; segregation of duties; files properly secured; No evidence of fraud! I now need to provide a copy of QB, Basis Calc, and support for COGS and Other Expense.
I do need to have the client sign an audit engagement letter.
Thanks for all responses!
