Start by confirming that the notice is a CP2000 or related IRS proposed-change letter. Write down the tax year, response deadline, proposed amount, and the income items the letter mentions.
Find the filed return for that year, then gather the income forms that match the IRS issue: W-2s, 1099-NEC, 1099-K, 1099-INT, 1099-DIV, retirement forms, brokerage forms, or business income records.
If the return was not filed or you cannot find it, note that clearly before calling. The file may need prior-year tax preparation or transcript review before a response path is clear.
