@pk how do you know the number on the notice is legit? if the notice is a scam the phone number is not to the IRS.
that leaves the taxpayer calling the IRS general number 800-829-1040
or
contact a local office of the IRS
or
using Audit Defense

Do not contact the IRS until you have spoken to TaxResources. They may contact the IRS on your behalf.
or a tax pro.
