What the IRS says: “The IRS made changes to your business return — the notice shows the adjustment and resulting balance, refund, or zero change.” Here’s what it actually means, your deadline, and exactly how to respond.
The CP210/CP220 pair covers post-filing adjustments to business accounts: penalty assessments, exam results, credit reversals (ERC adjustments arrive this way). The notice is terse — the transcript behind it tells the real story, and disputes have better odds when raised immediately in writing.
Notice family: Business Notices — Payroll deposits, information returns and business balance dues. Same escalation logic as individual notices, tighter timelines, and penalties that compound per form — worth responding to precisely.
21 days — pay-by date if a balance resulted.
Counted in calendar days from the notice date. The exact respond-by date printed on your notice always controls — check page 1.

Unexplained or wrong: written dispute with documentation now
Balance stands: pay or arrange; penalties may be abatable separately
A written dispute identifying the adjustment code, your records, and the requested correction — sent certified — is the formal counter. For penalty adjustments, fold in the reasonable-cause narrative.
Describe the notice and your side of it — use placeholders, never your SSN or account numbers (the letter keeps [YOUR NAME]-style fields so you fill in the real details privately before mailing). A mail-ready draft with an enclosure checklist comes back in ~20 seconds.
