What Is An IRS CP504 Notice

An IRS CP504 is a Notice of Intent to Levy, meaning the IRS is informing you that it will seize your state tax refund, wages, bank accounts, or other property if you do not pay your unpaid tax balance or make payment arrangements immediately. According to the IRS, the CP504 is issued under Internal Revenue Code Section 6331(d) and represents the final automated balance due reminder before the agency begins active enforcement. If you have received this notice, the IRS has already sent prior correspondence about the same unpaid balance and has not received payment or a response.

The CP504 includes your Social Security number, the date of the notice, and the specific tax year and form the balance relates to. It breaks the total amount owed into original tax, assessed penalties, and accrued interest. The notice also provides payment instructions, explains your right to appeal under the Collection Appeals Program, and describes the consequences of not responding. For a broader overview of how all IRS notices work and what different notice types mean, our complete guide to IRS correspondence covers every category from adjustments to enforcement.

Where CP504 Falls In The IRS Collection Sequence

The CP504 is the fourth notice in a five-step collection sequence that the IRS follows when an individual taxpayer has an unpaid balance. Each notice in this sequence carries more urgency than the last, and the CP504 marks the transition point from automated reminders to active enforcement. According to the IRS, the standard progression works as follows.

1. CP14: the initial notice that your tax return has an unpaid balance. Taxpayers who want to understand this first notice in the collection sequence can review our full guide to the CP14 balance due letter.
2. CP501: a first reminder that the balance remains unpaid.
3. CP503: a second reminder with stronger language, noting that the IRS has still not received payment.
4. CP504: the Notice of Intent to Levy, warning that the IRS will begin seizing assets if you do not act.
5. LT11 or CP90: the Final Notice of Intent to Levy, which grants you the right to request a Collection Due Process hearing within 30 days before the IRS proceeds.

The critical difference between the CP504 and the notices that came before it is that the CP504 authorizes the IRS to levy your state income tax refund without further notice. The final notices that follow, LT11 and CP90, authorize the IRS to levy everything else, including wages, bank accounts, and personal property.

What The IRS Can Seize After A CP504 Notice

After sending a CP504, the IRS can immediately intercept your state income tax refund, and after issuing a subsequent final notice, it can seize virtually any other asset or income stream you have. According to the IRS, property subject to levy includes the following.

• State income tax refunds. According to the IRS, this is typically the first asset levied after a CP504 because the agency can intercept it without issuing an additional notice.
• Wages, salaries, and commissions. The IRS can direct your employer to withhold a portion of each paycheck until the debt is satisfied.
• Bank accounts. The IRS can freeze funds in your checking and savings accounts and seize the balance up to the total amount owed.
• Business assets. Equipment, inventory, and accounts receivable can all be seized to satisfy a business or individual tax debt.
• Personal property. According to the IRS, the agency can seize your vehicle, your home, and other real or personal property. The IRS is one of the few creditors authorized to take a personal residence despite state homestead protections.
• Social Security benefits. The IRS can levy up to 15 percent of your monthly Social Security payments.

In addition to levies, the IRS can file a Notice of Federal Tax Lien, which is a public claim against your current and future assets. According to the IRS, a lien can damage your credit, make it difficult to sell or refinance property, and establish the government's legal priority over other creditors. The FAST Act also authorizes the State Department to deny, revoke, or limit your passport if your tax debt meets the threshold for seriously delinquent tax debt.

How To Respond To An IRS CP504 Notice

Respond to a CP504 as quickly as possible, ideally well within the 30-day window the IRS provides before taking levy action. Your best course of action depends on whether you agree or disagree with the amount the notice says you owe.

If You Agree With The Amount Owed

According to the IRS, you have several options for resolving the balance.

1. Pay in full. The fastest way to stop collection activity is to pay the entire balance shown on the notice. You can pay online at IRS.gov, by phone, or by mailing a check with the payment voucher included in the notice.
2. Set up an installment agreement. If you cannot pay the full amount at once, you may qualify for a monthly IRS payment plan or installment agreement. Our step-by-step guide to setting up structured payments covers the application process, balance thresholds, and how interest is calculated on the remaining amount.
3. Submit an Offer in Compromise. If your financial situation makes it unlikely you can pay the full debt even with a payment plan, you may be able to settle for less than you owe through a formal Offer in Compromise.
4. Request Currently Not Collectible status. If you have no ability to pay anything toward the debt, the IRS may temporarily pause collection activity by placing your account in Currently Not Collectible status. This does not eliminate the debt, but it stops levies while you remain unable to pay.

Taxpayers facing significant financial hardship may also qualify for the IRS Fresh Start program, which expands access to installment agreements and eases qualification thresholds for eligible individuals and businesses.

If You Disagree With The Amount Owed

If you believe the balance on the CP504 is incorrect, call the toll-free number printed on the notice immediately. According to the IRS, you can also request an appeal under the Collection Appeals Program before collection action takes place by following the instructions included in the notice. If you have already paid the balance or set up an installment agreement, contact the IRS at the number on the notice to confirm that your account reflects the payment or arrangement.

What Happens If You Ignore A CP504 Notice

Ignoring a CP504 causes the IRS to escalate to its final enforcement steps, beginning with the seizure of your state tax refund and progressing to levies on your wages, bank accounts, and personal property. According to the IRS, the next notice after the CP504 is typically the LT11 or Letter 1058, labeled "Final Notice of Intent to Levy and Notice of Your Right to a Hearing." This notice grants you the right to request a Collection Due Process hearing within 30 days, which is your last formal opportunity to challenge the proposed levy or present an alternative resolution before the IRS takes action.

If you do not respond to that final notice, the IRS can proceed with levying all available assets, filing a federal tax lien that becomes part of the public record and affects your credit, and, for balances meeting the seriously delinquent threshold, certifying your debt to the State Department for passport denial or revocation. Penalties and interest continue to accrue on the unpaid balance throughout this process, increasing the total amount owed with each month that passes.

Difference Between CP504 And CP504B

The CP504 is issued to individual taxpayers for unpaid personal income tax, while the CP504B is issued to businesses for unpaid business tax obligations such as employment taxes or excise taxes. According to the IRS, both notices carry the same intent to levy warning and the same level of urgency. If you received a CP504B for a business tax account, the response options and deadlines are the same as those described above for the standard CP504.

Frequently Asked Questions About The IRS CP504 Notice

How Serious Is A CP504 Notice?

A CP504 is one of the most urgent notices the IRS issues. According to the IRS, it is a formal Notice of Intent to Levy that authorizes the agency to begin seizing your state tax refund immediately and signals that levies on wages, bank accounts, and property will follow if you do not respond.

What Comes After A CP504 Notice?

The next step after a CP504 is typically the LT11 or Letter 1058, the Final Notice of Intent to Levy. According to the IRS, this final notice grants you 30 days to request a Collection Due Process hearing. If you do not respond, the IRS can proceed with levying your assets.

Is A CP504 Sent By Certified Mail?

The CP504 is typically sent by regular U.S. mail, not certified mail. According to the IRS, the subsequent final notice (LT11 or CP90) may arrive by certified mail because it triggers Collection Due Process hearing rights and the IRS must document delivery.

Can I Set Up A Payment Plan After Receiving A CP504?

Yes, you can still apply for an installment agreement after receiving a CP504. According to the IRS, you can apply online through the IRS Online Payment Agreement tool at IRS.gov or by calling the toll-free number printed on the notice. Setting up a payment plan stops the escalation toward active levy action as long as you remain current on your payments.

What Is An IRS Notice

An IRS notice is official correspondence that the Internal Revenue Service sends through the U.S. mail to inform you about a specific issue with your federal tax return or account. According to the IRS, the agency sends notices for reasons ranging from a simple math correction on your return to an unpaid balance or a request for additional documentation. Receiving a notice does not necessarily mean you made a mistake or owe additional tax, and many notices can be resolved by following the instructions printed on the document.

The IRS draws a practical distinction between two categories of mail. A notice is typically system-generated and addresses a specific account issue such as a balance due, a refund adjustment, or a processing change. A letter, by contrast, often comes from an individual IRS employee or department and may request information, confirm an action, or relate to an ongoing examination. Both arrive by U.S. mail, and both include a notice or letter number in the upper right corner of the first page that identifies exactly what the correspondence is about.

Common Reasons The IRS Sends Notices

The IRS sends notices most often because of a discrepancy on your tax return, an unpaid balance, or a change the agency made to your account. According to the IRS, the most frequent triggers include the following situations.

• Math errors or miscalculations on your return. The IRS caught an arithmetic mistake and adjusted your refund or balance accordingly.
• An unpaid tax balance. You filed a return but did not pay the full amount owed, or a prior balance remains on your account.
• Unreported or underreported income. Information the IRS received from employers, banks, or other third parties does not match what you reported on your return.
• Refund changes. The IRS applied your refund to a prior debt or adjusted the amount because of a credit recalculation.
• Identity verification. The IRS needs to confirm that you filed the return before releasing a refund.
• Unfiled returns. The IRS has no record of a required return for a specific tax year.

Not every IRS notice signals a problem. Some correspondence simply confirms a change you requested, acknowledges information you submitted, or notifies you that the IRS closed its review of your account.

Most Common Types Of IRS Notices

IRS notices fall into several broad categories based on why the agency issued them. Understanding which category your notice belongs to helps you assess its urgency and determine what kind of response it requires. The notice number, printed in the upper right corner of the first page, identifies the specific type.

Balance Due Notices

Balance due notices inform you that you owe money to the IRS. The most common is the CP14, which is the initial notice the agency sends when a filed return shows an unpaid amount. If you received a CP14 notice, our complete guide to this balance due letter explains the specific charges, deadlines, and response options. Subsequent reminders in the collection sequence include the CP501, CP503, and CP504, each carrying increased urgency.

Return Adjustment Notices

The IRS sends adjustment notices when it corrects an error on your return. A CP11 means the correction resulted in a balance you now owe. A CP12 means the correction resulted in a larger refund or a change to the amount you expected. A CP13 means the correction left your balance at zero with no additional amount owed and no refund due. According to the IRS, each of these notices explains exactly what changed and how the recalculated amount was determined.

Refund-Related Notices

These notices address changes to the amount or timing of your refund. A CP24 notifies you that the IRS found a difference between your estimated tax payments and the amount posted to your account, resulting in a potential overpayment credit. A CP49 notifies you that the IRS applied all or part of your refund to a prior tax debt. A CP32A asks you to contact the IRS so the agency can reissue a refund check.

Underreporter Notices

An underreporter notice means the income or payment information the IRS received from third parties does not match what you reported. The CP2000 is the primary notice in this category and one of the most frequently issued IRS letters. According to the IRS, a CP2000 is not a bill but a proposed adjustment that explains how the recalculated tax was determined. Taxpayers who receive a CP2000 notice can review our full guide to this underreporter letter for response steps and dispute options.

Identity Verification Notices

Identity verification notices ask you to confirm that you filed the return in question before the IRS will release a refund. Common examples include Letter 5071C and Letter 4883C. According to the IRS, these letters are part of the agency's efforts to prevent tax-related identity theft and typically require you to verify your identity online at IRS.gov or by calling the toll-free number printed on the letter.

Enforcement And Collection Notices

Enforcement notices signal that the IRS is preparing to take collection action against your assets. A CP504 warns that the IRS intends to levy your state tax refund. A CP90 or LT11 is a final notice of intent to levy bank accounts, wages, and other property, and it grants you the right to request a Collection Due Process hearing within 30 days. Certain enforcement notices, such as the CP90, may arrive as certified mail requiring your signature. A CP91 warns that the IRS intends to levy up to 15 percent of your Social Security benefits.

How IRS Notices Escalate From Reminder To Enforcement

IRS collection notices follow a specific sequence that grows more urgent at each stage, and each notice includes a deadline that starts the clock on the next escalation step. According to the IRS, the standard progression for an unpaid individual tax balance works as follows.

1. CP14: the initial balance due notice, sent shortly after you file a return with an unpaid amount.
2. CP501: a first reminder that your balance remains unpaid.
3. CP503: a second reminder with stronger language, noting that the IRS still has not received your payment or a response.
4. CP504: a notice of intent to levy your state income tax refund if you do not pay or contact the IRS to arrange a resolution.
5. CP90 or LT11: the final notice of intent to levy your wages, bank accounts, and other assets. This notice also informs you of your right to a Collection Due Process hearing, which you must request within 30 days.

Responding at any point in this sequence can slow or stop the escalation. Taxpayers who cannot pay the full amount may qualify for a structured IRS payment plan or installment agreement. Our guide to these structured repayment options covers the application process, payment thresholds, and how interest is calculated on the remaining balance. Those facing significant financial hardship may also qualify for the IRS Fresh Start program, which provides expanded installment terms and penalty relief for eligible individuals and businesses.

How To Verify Your IRS Notice Is Legitimate

A legitimate IRS notice arrives by U.S. mail, references a specific tax year and notice number, and never asks you to click a link or provide personal information through email or text. According to the IRS, the agency does not initiate contact with taxpayers by email, text message, or social media to request personal or financial information. Any communication that does so is a scam.

To confirm that a notice you received is genuine, take the following steps.

1. Look for the notice or letter number in the upper right corner of the first page. Every legitimate IRS notice includes one.
2. Log in to your IRS Online Account at IRS.gov. According to the IRS, many notices are viewable in your online account, which allows you to verify the correspondence directly against what the agency has on file.
3. Call the toll-free number printed on the notice itself, not a number from an email, a text, or a website you found through a search.
4. Check the return address. Legitimate IRS mail comes from a recognized IRS processing center, and the envelope typically includes "Department of the Treasury" or "Internal Revenue Service" in the return address.

According to the IRS, common red flags for fraudulent correspondence include demands for immediate payment by gift card or wire transfer, threats of arrest or deportation, and requests for credit or debit card numbers over the phone.

What To Do When You Receive An IRS Notice

Read the notice carefully, compare the information to your own tax records, and respond by the deadline printed on the document. Most IRS notices explain exactly what changed, why it changed, and what action you need to take. If you agree with the notice, follow the payment or documentation instructions provided. If you disagree, the notice will explain how to dispute the changes, which typically involves mailing a written response with supporting documents to the address on the notice.

The most critical step is acting before the deadline. Late responses can limit your options for disputing proposed changes or requesting a hearing. For a complete walkthrough of what to do when you receive an IRS notice, including what documentation to gather and how to organize your reply, our step-by-step response guide covers every stage from opening the envelope to confirming the issue is resolved.

When To Get Professional Help With An IRS Notice

Consider working with a CPA, Enrolled Agent, or tax attorney when your notice involves a large balance due, a proposed audit, an enforcement action such as a levy or lien, or a situation you do not fully understand. A qualified tax professional can communicate directly with the IRS on your behalf, identify resolution options you may not be aware of, and ensure your rights as a taxpayer are protected throughout the process. According to the IRS, you can authorize a representative by filing Form 2848, Power of Attorney and Declaration of Representative. Simple notices confirming a small refund adjustment or a zero-balance correction typically do not require professional assistance.
