IRS CP523 Installment Agreement Default — What It Means & What To Do


A CP523 is a Notice of Intent to Terminate Your Installment Agreement. It means the IRS believes your existing payment plan is in default.

If no action is taken, your agreement may be terminated and the IRS may resume full collection enforcement.

You generally have 30 days from the date of the notice to respond before termination becomes final.

What Triggered This Notice?


CP523 is typically issued when:

• A required payment was missed

• A new tax balance was incurred

• Required tax returns were not filed

• Financial information was not updated when requested

The IRS is warning that your payment plan is at risk.


What Happens If the Agreement Is Terminated?


If your Installment Agreement is terminated:

• The IRS may issue levy notices

• Wage or bank levy action may follow

• Collection enforcement may resume

• You may lose streamlined agreement eligibility

This is a warning stage — but enforcement may follow if ignored.


What the IRS Can and Cannot Do at This Stage


At this stage:

• Your agreement is still active during the 30-day window

• You may have options to reinstate or restructure

After termination becomes final:

• Collection enforcement may resume

• The IRS may proceed with levy notices


This Is NOT the Same As


CP14 / CP501 / CP503 — Early balance-due notices

CP504 — Intent to levy notice

CP90 / CP297 — Final levy notices

90-Day Deficiency Notice — Tax Court deadline

CP523 specifically applies to installment agreement default situations.
