What the IRS says: “The IRS adjusted your business return and a balance is due, combining tax, penalties and interest.” Here’s what it actually means, your deadline, and exactly how to respond.
Functionally CP210's balance-due presentation — frequently the vehicle for employment tax exam results and ERC clawbacks. Same discipline: transcript first, then dispute or resolve, never ignore.
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 on the notice.
Counted in calendar days from the notice date. The exact respond-by date printed on your notice always controls — check page 1.
Transcript the period; identify the adjustment source
Agree: pay or IA before FTD-style escalation
Disagree: written protest with the documentation the adjustment ignored
Penalties: reasonable-cause abatement request alongside
Same written-dispute framework as CP210 — specificity about the transaction and documentation is what moves business cases.
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.
