IRS CP523 Notice: Curing Default, Appeals, and Collection Actions

An IRS CP523 notice is a 30-day warning that you have defaulted on your installment agreement and the IRS intends to terminate it and begin seizing your assets to collect what you owe.1Internal Revenue Service. Understanding Your CP523 Notice You have 30 days from the date on the notice to cure the default, request an appeal, or arrange a new resolution before the IRS follows through. Acting inside that window matters more than with almost any other IRS letter you’ll receive, because once the agreement is terminated the full remaining balance comes due immediately and the IRS’s collection tools open up.

Why the IRS Sent You This Notice

The CP523 arrives when the IRS considers your installment agreement in default. Federal law gives the IRS several grounds to terminate an agreement, and missing a payment is only the most obvious one.2Office of the Law Revision Counsel. 26 USC 6159 – Agreements for Payment of Tax Liability in Installments You can also default by:

  • Owing a new tax balance. If you file a return and don’t pay what you owe by the due date, that alone defaults your existing agreement, even if every installment payment has been on time.
  • Failing to provide updated financial information the IRS has requested, especially under a partial-payment installment agreement.
  • Providing inaccurate or incomplete financial information before the agreement was accepted.
  • Experiencing a significant improvement in your finances that the IRS determines warrants modifying or ending the agreement.

The Internal Revenue Manual treats a new balance on a related account, such as a sole proprietorship tied to your personal agreement, the same way it treats a missed payment.3Internal Revenue Service. IRM 5.14.11 – Defaulted Installment Agreements This catches people constantly. Every scheduled payment lands on time, then a new return shows a balance owed, and suddenly the whole agreement is in jeopardy.

Read the notice carefully. It identifies the specific reason for the default and the exact amount you need to pay or the action you need to take to fix it.4Internal Revenue Service. IRS Notice CP523 – Notice of Intent to Levy and Intent to Terminate Installment Agreement

Curing the Default Within 30 Days

Federal law requires the IRS to give you at least 30 days’ notice before terminating an installment agreement, along with an explanation of why.2Office of the Law Revision Counsel. 26 USC 6159 – Agreements for Payment of Tax Liability in Installments The CP523 is that notice, and the simplest response is to fix whatever caused it. Missed a payment? Make it. Owe a new balance from a return you just filed? Pay it. Failed to file a required return? File it.

If the IRS reinstates your agreement, expect a reinstatement fee of $89. Taxpayers at or below 250% of the federal poverty guidelines pay a reduced fee of $43, and that reduced fee is waived entirely for those who agree to make payments electronically through a debit instrument.5Internal Revenue Service.

Appealing a CP523 You Believe Is Wrong

If the default notice is incorrect, say because you already made the payment or the IRS applied it to the wrong account, you can appeal through the Collection Appeals Program. File Form 9423, Collection Appeals Request, and send it to the address shown on the CP523.4Internal Revenue Service. IRS Notice CP523 – Notice of Intent to Levy and Intent to Terminate Installment Agreement For installment agreement disputes, you don’t need to first request a conference with the assigned employee’s manager, which is normally required before a CAP appeal on other collection actions.7Internal Revenue Service. Preparing a Request for Appeals

One boundary to know: the CAP decision from the IRS Office of Appeals is final. You cannot take a CAP outcome to Tax Court.8Taxpayer Advocate Service. Collection Due Process (CDP) A Collection Due Process hearing does preserve Tax Court review, but it isn’t available at the CP523 stage. That right attaches later, if the IRS sends a separate CDP levy notice after your agreement has been terminated.

What Termination Actually Does to Your Balance

If you don’t cure the default or successfully appeal, the IRS terminates the agreement at the end of the 30 days. The full remaining balance, including all accumulated penalties and interest, becomes due immediately.4Internal Revenue Service. IRS Notice CP523 – Notice of Intent to Levy and Intent to Terminate Installment Agreement The payments you made under the agreement still count toward your total liability, but the remainder is no longer spread across future months.

The math gets uncomfortable quickly. Interest keeps running on unpaid tax, and the failure-to-pay penalty, which sits at 0.25% per month during an active installment agreement, jumps back to 0.5% per month once the agreement is terminated. So the balance you owe after termination is almost always larger than the simple difference between what you started with and what you paid in.

Collection Actions That Follow

Once the agreement is terminated and appeal rights are exhausted, the IRS has its full enforcement toolkit available.

Federal Tax Liens

The IRS can file a Notice of Federal Tax Lien, which creates a legal claim against everything you own, including your home, car, bank accounts, and other property or rights to property.9Office of the Law Revision Counsel. 26 USC 6321 – Lien for Taxes A lien doesn’t seize anything by itself. It secures the government’s interest ahead of most other creditors, shows up when lenders check public records, and makes selling property or refinancing a mortgage difficult. You can appeal a proposed lien filing through the Collection Appeals Program before it’s filed.4Internal Revenue Service.

Levies and Seizures

A levy is the IRS actually taking property. The IRS can garnish wages, drain bank accounts, seize a car or real estate, and reach accounts receivable, retirement account distributions, rental income, and the cash value of life insurance.10Internal Revenue Service. What Is a Levy A wage levy is continuous. Once in place it takes a portion of each paycheck until the debt is satisfied or the levy is released. Bank levies work differently. The bank freezes the account for 21 days, giving you a narrow window to resolve the situation before the funds are turned over.11Internal Revenue Service. Levy

Passport Restrictions

If your total tax liability, including penalties and interest, exceeds $66,000, the IRS can certify the debt as seriously delinquent to the State Department. The State Department will generally refuse to issue or renew your passport and may revoke an existing one.12Internal Revenue Service. Revocation or Denial of Passport in Cases of Certain Unpaid Taxes The threshold is adjusted annually for inflation. Entering into a new installment agreement or having your account placed in Currently Not Collectible status are among the ways to reverse the certification.

If You Can’t Simply Pay the Default

Even after termination you have options, and even before termination you can propose an alternative resolution instead of curing the old agreement. Ignoring the situation is the worst move. Resolving things after a levy is much harder than resolving them before.

A New or Reinstated Installment Agreement

You can request a new installment agreement, though the IRS will look at you more closely after a default. If your debt excluding interest and penalties is under $10,000 and you haven’t defaulted on an agreement in the past five years, federal law actually requires the IRS to accept an installment agreement when you offer to pay in full within three years.2Office of the Law Revision Counsel. 26 USC 6159 – Agreements for Payment of Tax Liability in Installments For larger amounts, approval is discretionary and the IRS may require updated financial disclosures.

Partial Payment Installment Agreement

If you cannot afford to pay the full balance before the collection statute expires, a Partial Payment Installment Agreement lets you make smaller monthly payments based on what you can actually afford. The IRS will generally require you to tap equity in assets first, and it reviews your finances every two years to see if your situation has improved.13Internal Revenue Service. IRM 5.14.2 – Partial Payment Installment Agreements and the Collection Statute Expiration Date Any balance still unpaid when the statute expires is written off.

Currently Not Collectible Status

If paying anything at all would leave you unable to cover basic living expenses, you can ask the IRS to report your account as Currently Not Collectible. This pauses collection activity, with no levies or garnishments, though the debt itself doesn’t disappear and interest and penalties continue to accrue.14Internal Revenue Service. Temporarily Delay the Collection Process The IRS reviews your finances periodically to decide whether collection should resume. If the ten-year collection statute runs while you remain in CNC status, the remaining debt is eventually forgiven, although certain actions can extend that clock.

Offer in Compromise

An Offer in Compromise lets you settle your total tax debt for less than you owe, but it’s harder to get than most people expect. The IRS accepts these only when it concludes it can’t collect the full amount by any other means, or when there is genuine doubt that you owe the tax at all. Submitting an offer requires a $205 application fee and an initial payment, and the process typically takes several months. After a defaulted agreement, the IRS will look at an OIC application with extra skepticism, but a well-documented offer based on current inability to pay can still succeed.
