We have Audit Support, which includes correspondence notices such as CP2000. Please follow the procedure below to speak with a representative.
Have your notice handy, as well as a copy of your tax return. You can go over the lines of the CP2000 and the rep can help explain what the IRS is proposing.
We don't have access to any of your data, so if you want to discuss it via this public forum, you will need to provide all the details. I do not recommend that you seek help through the Answer Exchange.
