CP523: Intent to terminate an installment agreement

Prepared by TaxRZR editorial team · IRS sources checked 2026-10-29 (ET) · professional review pending · This page’s Source Notes

CP523 says your installment agreement is in default and the IRS intends to terminate it and may levy assets. Read the stated reason rather than assuming it is only a missed monthly payment.

Notice-specific source status. Expanded CP523 guidance checked against the IRS CP523 instructions, current payment-plan guidance and Publications 1660 and 594 on October 29, 2026. This is an editorial source check, not professional review or a calculation of your appeal deadline.

What the IRS can do next

If the default is not resolved or appealed, the agreement may terminate and collection can resume, subject to levy restrictions. Reinstatement may involve a fee or paying a new liability.

Contact the IRS immediately, no later than 30 days from the notice date, and before the stated termination date.

Publication 1660 describes a 30-day appeal period for proposed termination. If the agreement terminates, another 30-day appeal period generally applies, but a decision already appealed before termination cannot be appealed again. Levy is generally prohibited for 30 days after termination and during a timely appeal, subject to exceptions. Use your actual notice and ask the IRS to confirm the applicable dates.

Next step

Call the notice office now about curing the default or reinstating the plan. If you disagree, ask how to submit a timely Collection Appeals Program appeal.

Steps to work through

  1. 01Read the default reason and gather proof of payments and filed returns.
  2. 02Make any required cure payment before termination if you can and confirm the cure with the IRS.
  3. 03If the payment is no longer affordable, discuss modification or hardship instead of promising an unsustainable amount.
  4. 04Keep a written call record and preserve appeal rights; a call alone may not resolve the default.

This is a threatened loss of an existing payment arrangement

CP523 is not simply another reminder to pay a balance. It says your installment agreement is in default and the IRS intends to terminate it. The important questions are why the default occurred, what will cure it and whether you disagree with the proposed termination. Locate the original approval and later modifications so you can compare the actual terms with the reason stated in the notice.

Do not assume that default always means one missed monthly payment. The payment-plan rules also require current filings and payment of new taxes. A new liability, an unsuccessful debit or another compliance problem may need attention. Read the notice’s explanation and ask the IRS to identify the exact unmet condition. Sending the usual monthly amount may not resolve a different condition that caused the default.

Separate the cure date, proposed termination and appeal periods

The IRS CP523 page says to contact the agency as soon as possible and no later than 30 days from the notice date. It also directs payment before the termination date to prevent termination where that cures the default. Read your particular notice for the required action and dates. Do not turn those instructions into a promise that any payment, made at any point in the next month, will save the agreement.

Publication 1660 gives 30 days from the notice of intent to terminate to request an appeal. Unless you appeal within that period or cure the default, the agreement terminates. The publication also describes an additional 30-day appeal period after termination. That later opportunity is not a reason to ignore CP523 now, and it does not permit a second appeal of the same decision if you already appealed before termination.

If the stated default is a missed or misapplied payment

Gather bank statements, debit records and payment confirmations for the disputed installments. Compare the payment date, amount and tax period with the agreement. A debit you expected but that never occurred differs from money taken by the IRS and credited incorrectly. Explain which happened and ask what evidence or payment is needed. If a bank account changed, identify whether the IRS had accepted the new instructions.

Ask how to prevent a duplicate debit while curing the problem, and verify the correct payment destination and period. Keep proof of any catch-up payment and contact the notice number to confirm the IRS recorded the corrective action. The CP523 instructions specifically recommend calling even after taking corrective action. A payment confirmation alone does not prove reinstatement or establish that every reason for default has been resolved.

If new tax or missing returns caused the default

Identify which new balance or unfiled return the IRS says violates the agreement. Obtain the relevant notices and separate that problem from the old installment debt. Ask whether the new tax must be paid in full, whether the agreement can be revised and what filing evidence is required. The IRS CP523 page warns that reinstatement may require payment of a new liability and may involve a fee.

Do not assume the original agreement automatically absorbs every later tax year. A proposed revision must be accepted and must address current compliance. Review withholding, estimated payments or business deposits so the same problem will not recur next year. If you cannot meet both current obligations and the existing monthly payment, explain the shortfall promptly and prepare financial records instead of promising a catch-up amount you cannot sustain.

If you disagree with termination, use the installment appeal procedure

Contact the notice number and explain the factual or procedural reason you dispute termination. If the problem is not resolved, state that you want to appeal. Publication 1660 explains that an installment-termination appeal need not be written unless a revenue officer sent the notice; in that situation a written request is required, preferably Form 9423. Preserve a dated record of the request and follow the notice’s delivery instructions.

A manager conference is recommended but is not required before appealing an installment-agreement termination. Do not apply the two- and three-business-day manager-conference rules for certain lien or levy CAP cases to this installment-agreement appeal. For a written request mailed within the appeal period, keep proof of a timely postmark. Ask the collection office where it must go rather than sending it to a general payment address.

What collection protection does—and does not—mean

Current IRS payment-plan guidance describes general restrictions on enforced collection while a plan is considered or in effect, for 30 days after rejection or termination, and while an appeal is evaluated. These protections have conditions and exceptions. Verify the actual status of your agreement and appeal with the IRS; a telephone conversation about your finances is not necessarily an accepted request or a filed appeal.

Do not translate a levy restriction into a guarantee that no lien can be filed, no refund can be applied or no interest can accrue. The IRS can generally apply future refunds to tax debt while scheduled agreement payments remain due. If a levy already exists, ask specifically what happens to it; do not assume requesting reinstatement automatically releases money. Get prompt individual help if collection and appeal dates overlap.

A terminated plan can expose the account to further collection

The CP523 instructions warn that failure to respond can lead to termination and collection, including filing a federal tax lien or levying wages or bank accounts. A lien is a legal claim; a levy takes property. Do not expect a new CP14 or an entirely new reminder sequence before the IRS acts. Prior final levy notices and the account’s existing hearing history matter.

CP523’s installment appeal is not the same as a CDP hearing under LT11, Letter 1058 or CP90. If another notice gives CDP rights, follow that separate deadline and procedure as well. CAP does not provide judicial review of its decision. The CP523 page also mentions possible passport consequences, but certification has separate legal criteria; this letter alone does not establish that your passport has been revoked.

Reinstatement should solve the reason for failure

Before accepting a revised arrangement, test it against your actual income, necessary expenses and current taxes. Ask about the reinstatement fee and any available low-income fee relief under current IRS rules. If income fell or essential costs rose, explain that change with records. A higher promised payment may stop one difficult conversation but create another default when the next installment becomes due.

If an affordable full-payment plan is not feasible, discuss whether another collection alternative is appropriate. Publication 594 describes financial-information requirements and alternatives, including hardship collection delay and partial-payment arrangements. None is guaranteed simply because the first agreement failed. Interest and applicable penalties generally continue, and temporary collection delay does not forgive the balance. A proposed alternative also does not replace a timely termination appeal if you dispute that decision.

What to do this week

Record the notice date, termination date and appeal instructions. Gather the agreement, payment evidence and any new-tax or missing-return notices. Contact the IRS promptly to identify the required cure, confirm whether reinstatement is available and preserve the appropriate appeal if disagreement remains. Keep the representative’s name and a record of the office, delivery method and next follow-up date for every request you make.

Then confirm the outcome rather than assuming silence means approval. Determine whether the plan is active, what monthly payment is due and whether direct debit instructions have changed. Keep making payments required by the operative arrangement unless the IRS confirms otherwise. Seek qualified help immediately if termination has already occurred, a levy is imminent or an appeal deadline is disputed. The goal is a documented, workable resolution, not simply sending one more payment.

Common misreadings

  • This is not simply another monthly bill.
  • Do not assume a payment or an unconfirmed phone arrangement reinstates your agreement.
