A CP523 means your installment agreement is in default — usually from a missed payment or new unfiled/unpaid taxes — and the IRS intends to terminate it and may levy. You can usually save the agreement by acting fast.
A CP523 is the IRS telling you your payment plan is about to be terminated. Common triggers: a missed monthly payment, a new tax debt you didn’t pay, or an unfiled return — staying current on everything is a condition of every installment agreement. The notice warns of termination and potential levy. The good news: agreements can often be reinstated if you act quickly — catch up the missed amount, file the missing return, or contact the IRS to restructure. Ignore it, and you lose the plan’s protection and re-enter active collections.
Often yes — catching up missed payments or fixing the compliance issue and contacting the IRS can reinstate it, sometimes with a reinstatement fee.
New unpaid taxes or an unfiled return also default an agreement — staying current on all filings and taxes is a condition of the plan.
