What to do after you receive an IRS notice
First: do not panic and do not throw the letter away. Every IRS notice has a code in the upper right corner (CP or LTR followed by a number). That code tells you exactly what the IRS is asking for and what the deadline is.
Read the whole letter before you react. Many notices are informational and require no reply. Others give you 30 or 60 days to respond — missing that window can turn a simple issue into a much harder one.
Compare what the notice says to your return. If the numbers do not match, gather the supporting documents (W-2s, 1099s, receipts). If you agree with the change, follow the instructions on how to pay or set up a payment plan. If you disagree, you have the right to respond in writing.
If any of this feels unclear, that is the moment to bring in an Enrolled Agent. As your authorized representative, Julius can speak directly to the IRS on your behalf using Form 2848 — you no longer have to.
