What does an IRS CP523 notice mean?
A CP523 warns that your installment agreement is in default and the IRS intends to terminate it. Once terminated, the full remaining balance becomes due and the IRS can resume enforced collection, including levies. The notice explains what caused the default and how to cure it.
Why did you receive a CP523?
Common causes include missing one or more payments, failing to file a required return, incurring a new balance, or not paying enough estimated tax while under the agreement.
How to respond to a CP523 notice
Act before the deadline. Bring the agreement current by paying missed amounts, file any delinquent returns, and pay any new balances. You can request reinstatement of the agreement (a fee may apply) or propose revised terms if your financial situation changed. Direct debit reduces the risk of future defaults.
What happens if you ignore it?
The IRS terminates the agreement, demands the entire balance, and may levy your wages and bank accounts or file a federal tax lien. Reinstating after termination is harder than curing the default now.
Common resolutions
- Pay the missed amounts immediately
- Request reinstatement
- Propose revised terms
