An IRS payment plan default puts your installment agreement at risk of termination and can return your account to active collection.
A CP523 or Letter 2975 explains why the IRS considers the agreement in default, what you must do to prevent termination, and how much time you have to respond.
In many cases, the notice gives you 30 days from its date to correct the default. IRS collection procedures also generally provide a period before levy action can proceed after a default notice, giving you time to address the problem before the IRS takes further enforcement action. The exact requirements depend on why the agreement defaulted and what the notice says.

Before making another payment or requesting a new agreement, it is important to understand the status of the account and the reason the IRS terminated or proposed to terminate the existing arrangement.
Key Takeaways
- A CP523 or Letter 2975 means the IRS has identified a problem with an existing installment agreement and is moving toward termination unless the default is corrected.
- The notice generally provides 30 days from its date to resolve the issue before the agreement terminates.
- Missed payments, new tax liabilities, and unfiled returns can all cause an installment agreement to default.
- Reinstatement or modification may be available if you correct the underlying problem and meet the IRS requirements.
- If the existing monthly payment is no longer affordable, alternatives may include a revised installment agreement, Currently Not Collectible status, or an offer in compromise.
- The longer a default remains unresolved, the greater the risk that the IRS will resume active collection efforts.
What an IRS Payment Plan Default Means
An IRS payment plan default occurs when a taxpayer fails to meet a condition of an installment agreement. The most common causes are missed payments, new tax liabilities, or failure to file a required tax return.
Installment agreements are authorized under Internal Revenue Code Section 6159. A default does not eliminate the underlying tax debt. Instead, it puts the agreement at risk and can allow the IRS to resume collection activity.
The first step is identifying exactly why the IRS recorded the default. The appropriate response depends on the problem. A taxpayer who missed one payment may have a different path to reinstatement than someone who has accumulated a new tax balance or failed to file a return.
Reviewing your IRS account transcripts can help establish what happened, which tax periods are affected, and whether additional liabilities have been added since the agreement was established.
Appealing a Proposed Termination
Taxpayers who disagree with a proposed or completed termination can request a review through the Collection Appeals Program by filing Form 9423.
This request generally must be made within 30 days of the notice, or within an additional window after the agreement has actually terminated. While a timely appeal is pending, the IRS generally pauses levy action on the disputed tax periods while the Independent Office of Appeals reviews the termination decision.
An appeal does not guarantee the termination will be reversed, and if Appeals agrees with the IRS determination, collection can proceed.
Details on the process are available in Form 9423 and IRS Publication 1660.
CP523, Letter 2975, and Response Deadlines
The IRS uses different notices to tell taxpayers that an installment agreement is in default or is subject to termination. CP523 is commonly issued to individual taxpayers when an installment agreement is in default.
Other accounts may receive different notices, including Letter 2975. The notice is important because it identifies the reason for the default and explains what the IRS requires to prevent termination. Read the entire notice before making a payment or contacting the IRS.
What Is Printed on the Notice?
The notice should explain:
- Why the installment agreement is in default
- What amount, if any, must be paid to prevent termination
- The deadline for responding
- The remaining balance subject to collection
- How to contact the IRS about the account
Do not assume that making your regular monthly payment will resolve the problem. If the default resulted from a new tax liability or an unfiled return, the IRS may require additional action before the agreement can be reinstated.
How Long Do You Have to Respond?
The notice generally gives you 30 days from the date printed on the notice to correct the default or otherwise address the IRS requirements.
That deadline is important. The date on the notice, rather than the date you happen to open the letter, controls the response period. If you received the notice late, act promptly rather than assuming the full 30 days remain.
Missing the deadline does not necessarily mean the IRS will levy your bank account or wages immediately. However, it can cause the installment agreement to terminate and move the account closer to active collection.
What Happens After an IRS Payment Plan Defaults?
Termination of an installment agreement removes the protection provided by the existing arrangement. The IRS can then pursue collection of the outstanding tax debt through its normal collection procedures.
Interest and applicable penalties continue to accrue while the balance remains unpaid. Depending on the account, the IRS may also pursue or strengthen collection measures such as a federal tax lien or levy.
The IRS Internal Revenue Manual provides collection procedures concerning the timing of levy action following an installment agreement default notice. In general, the IRS does not immediately levy after issuing a CP523 or similar notice, which can provide additional time to resolve the account. That period should not be treated as a guarantee that a levy cannot occur. The specific circumstances of the account and the IRS’s collection actions matter.

How to Reinstate or Modify an IRS Payment Plan
The appropriate response to a default depends on the reason the agreement failed. Start by correcting the underlying compliance problem rather than sending another payment without confirming what the IRS requires.
- Review the default notice. Identify the reason for default, the amount the IRS says must be paid, and the response deadline.
- Correct the underlying problem. Bring missed payments current, file outstanding returns, or address a new tax balance as required.
- Contact the IRS unit identified on the notice. Keep records of calls, including the date, representative’s name, and instructions provided.
- Request reinstatement or modification. If the existing agreement no longer works financially, updated terms may be available.
- Provide financial information when required. The IRS may request additional information about income, expenses, assets, and liabilities before approving revised terms.
- Confirm the status of the agreement. Do not assume that making a payment automatically reinstates the installment agreement. Verify that the IRS has restored or modified the agreement.
Fees can apply when establishing, reinstating, or modifying an installment agreement. The amount depends on the type of request and how it is submitted. Low-income taxpayers may qualify for reduced fees or a waiver in certain circumstances. Review the current IRS payment plan information and Form 9465 instructions for the applicable requirements.
What If You Cannot Afford the Existing Payment?
A default may indicate that the original installment agreement no longer reflects your financial circumstances. If your income has fallen, expenses have increased, or a new tax liability has made the existing payment unrealistic, asking for the same arrangement again may not solve the problem.
Depending on your circumstances, alternatives may include:
Revised Installment Agreement
The IRS may allow a taxpayer to modify an existing agreement when the financial information supports different payment terms. The available option depends on the balance, compliance history, financial circumstances, and other IRS requirements.
Currently Not Collectible Status
Currently Not Collectible status may be appropriate when paying the IRS would prevent you from meeting necessary living expenses. The tax debt is not forgiven, and interest and penalties generally continue to accrue, but the IRS may temporarily suspend active collection while the taxpayer remains in hardship status.
Offer in Compromise
An offer in compromise may allow a taxpayer who qualifies to settle federal tax debt for less than the full amount owed. The IRS evaluates the taxpayer’s financial circumstances and ability to pay before accepting an offer.
These options serve different purposes. The right approach depends on what the taxpayer can realistically afford, how much is owed, and what the IRS can collect under the applicable rules.
How to Prevent Another IRS Payment Plan Default
Once a payment plan has been reinstated or modified, maintaining compliance becomes critical. A new default can make future arrangements more difficult and may reduce the options available to resolve the account.
Keep a calendar that tracks:
- Monthly installment payments
- Tax return filing deadlines
- Estimated tax payment deadlines
- New tax liabilities
- Changes to your bank account or payment information
Direct debit can reduce the risk of missing a scheduled installment, but the account must have sufficient funds when the IRS attempts the withdrawal. If your banking information changes, update it before the next payment is due.
The same principle applies when your financial circumstances change. If you anticipate a new tax liability or can no longer afford the agreed monthly payment, address the issue before the next payment is missed. Early action can preserve more options than waiting until another default notice arrives.
