Change to Your Business Tax Account (CP210/CP220)

A CP210 or CP220 follows some adjustment event on the account. Frequent real-world causes:

• Corrections you requested, such as an amended or adjusted Form 941, finally posting.
• IRS corrections of math or processing errors on an original return.
• Mismatches between reported federal tax deposits and what the IRS shows received, a classic source of surprise balances for employers whose payroll provider missed or misapplied a deposit.
• Penalty or credit adjustments flowing from an examination or claim, including employment tax credit claims that were adjusted.

The notice states what changed, but not always in satisfying detail. The reliable way to see the full picture is the account transcript for that period, which shows each assessment, credit, and adjustment line by line; our guide to reading what you owe explains how to pull one.

If the change is right and shows a balance, the IRS instruction is simple: "make your payment (if you have a balance) by your due date." After that date, interest accrues on the unpaid amount and a late payment penalty applies. Businesses that cannot pay in full can request an installment agreement; the options and trade-offs are in our payment plan guide.

If the change is wrong, contact the IRS at the toll-free number in the top right corner of the notice, with the return, deposit records, and any correspondence that triggered the adjustment in front of you. Penalties included in the change can be challenged on reasonable cause grounds or through first-time abatement where the history supports it. If normal channels fail, the Taxpayer Advocate Service is the escalation path the IRS itself lists on these notices.

For a growing company, a CP210/CP220 balance is rarely the whole story. An employment tax adjustment for one quarter often signals the same issue in adjacent quarters, and unpaid employment tax carries the sharpest personal edge in the tax code: the withheld portion can be assessed against owners and officers personally as a trust fund recovery penalty if it goes unresolved, proposed via Letter 1153. Treat one of these notices as a prompt to reconcile the whole payroll tax account, not just the period on the page. That reconciliation is also your leverage: a business that arrives at the IRS with quarter-by-quarter deposit records and a clear story about what went wrong gets adjustments corrected and penalties abated far faster than one disputing a single line in isolation. If the numbers are material, our 941 payroll tax debt guide lays out the order of operations.
