I received CP2000 from IRS indicated I owe tax for 2015.
My parents filed me as dependent in their tax return and I had my own tax return in 2015. My mother purchased the mutual funds a few year ago and opened the account with both of our names. She sold the mutual funds and received Form 1099-B with my SSN as the recipient's ID. My parents filed this transaction in their tax return 2015.
I received the letter of CP2000 from IRS indicated that I owe tax of $2,672 for the total gross amount of $20,784 which including the cost of $16,162.
How do I explain to IRS?
Thanks!
