With Notice CP11 & CP11A the IRS has proposed an adjustment to your return based on information they have. This information is usually not wrong, but lacks proof to offset it. TaxHelpLaw will show you what documents you need to win! But you only have 60 days to respond.
This is not a bill and not an audit but is a math adjustment based on third party records. The IRS could audit you later. When you respond to the IRS be very careful what you say and what you send them. These will be used against you! Please follow the Prep Steps for IRS Notice CP11 and see Mr. Hopkins in Colorado Springs, Pueblo or Denver before you act!
