IRS CP523 Installment Agreement Default Response Kit

What Is IRS CP523?

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

This can happen if:

• A payment was missed

• A new tax balance was incurred

• Required tax returns were not filed

• Financial information was not updated

If the agreement is terminated, the IRS may resume full collection action, including levy enforcement.

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

What Happens If You Ignore CP523?

If no action is taken:

• Your Installment Agreement may be terminated

• The IRS may issue levy notices

• Collection enforcement may resume

• You may lose streamlined agreement eligibility

This is a warning stage — but enforcement may follow.
