IRS Notice CP210 / CP220
Adjustment to Business Tax Account
CP210 (and the related CP220) notifies a business that the IRS has adjusted its tax account — typically a math correction, a credit transfer, or a penalty assessment on a payroll or business return. The notice shows the adjusted balance and may demand additional tax, penalties, and interest.

Notice CP210 / CP220 in Plain English
CP210 (and its variant CP220) tells a business that the IRS adjusted its account — usually a math change, a credit transfer, or a penalty on a payroll or corporate return. It's a business-facing bill: the numbers changed, and the balance is now due.
Why the IRS sent you a CP210 / CP220
A payroll tax return (941, 940) had a deposit-timing or math discrepancy.
A prior estimated payment or credit was moved between periods.
A late-filed return triggered a failure-to-file or failure-to-deposit penalty assessment.
The IRS corrected a duplicate credit that was originally posted in error.
What Happens If You Ignore Notice CP210 / CP220
If the adjustment is correct and unpaid, the IRS will follow with CP161 / CP504-B and ultimately levy business bank accounts and accounts receivable. If the adjustment is wrong and not contested in writing, the new balance becomes presumed correct.
Every day you wait, penalties compound, interest accrues, and your options shrink. The IRS does not negotiate well with silence — they escalate.
What To Do About Notice CP210 / CP220
Compare the adjustment to your filed return line-by-line. If the IRS is right, pay or arrange an installment agreement. If wrong, file a written protest before the 30-day window closes — businesses have a narrower window than individuals to dispute.

- 3
For trust-fund payroll adjustments, separately assess personal §6672 exposure — the corporate CP210 is only half the picture.

Businesses have a narrower dispute window than individuals; file a written protest well before the 30-day mark.
