What Happens If You Don’t Respond to a CP504?

Key Takeaways 

• An IRS CP504 notice warns that you have an unpaid tax liability and that the IRS may take further collection action if you do not respond. 

• Ignoring a CP504 notice may result in an eligible state tax refund levy, continued interest and penalties, and additional collection notices. 

• A CP504 notice generally does not authorize the immediate seizure of wages or bank accounts for individual income tax liabilities. The IRS typically must issue a separate final notice of intent to levy and provide an opportunity for a Collection Due Process (CDP) hearing. 

• The CP504 deadline is generally 30 days from the notice date. If you receive an LT11 or Letter 1058, review the separate deadline for requesting a CDP hearing, which is generally 30 days. 

• If you cannot pay your full tax liability, you may qualify for an IRS installment agreement, an offer in compromise, currently not collectible status, or penalty relief, depending on your circumstances. 

• If you receive a CP504 notice, verify your balance, review your payment history, and contact the IRS promptly. A qualified tax professional can help you understand your collection options and respond to potential enforcement actions. 

Receiving a CP504 notice from the Internal Revenue Service (IRS) means you have an unpaid tax balance that requires your attention. If you ignore a CP504 notice, the IRS may levy your state tax refund, continue collection efforts, and eventually pursue other assets if the balance remains unresolved and applicable legal requirements are met. Penalties and interest may also continue to increase your tax liability. 

Although a CP504 notice is serious, it does not mean the IRS will immediately garnish your wages or seize your bank account. For most individual income tax liabilities, the IRS generally must provide a separate formal notice of intent to levy and an opportunity to request a Collection Due Process (CDP) hearing before taking those actions. State tax refund levies are an important exception. 

The best course of action is to review the notice, verify your balance, and contact the IRS promptly, even if you cannot afford to pay the full amount. Understanding what happens if you don’t respond to a CP504 can help you protect your finances and explore available tax resolution options before collection efforts escalate. 

What Is an IRS CP504 Notice? 

An IRS CP504 notice is a balance-due notice sent to taxpayers who have not paid an outstanding federal tax liability. It warns that the IRS may take collection action if the balance remains unpaid and explains how to pay or contact the agency. The notice generally includes the amount due, applicable penalties and interest, payment instructions, and a deadline for taking action. 

Why Did I Receive a CP504 Notice? 

You may receive a CP504 notice because the IRS has not received payment for taxes you owe. The balance could relate to an individual income tax return, an adjustment made by the IRS, or another unpaid tax liability. 

For example, suppose you filed your federal tax return but could not pay the full $4,000 balance. If the IRS previously sent balance-due notices and still has not received payment, it may send a CP504 notice warning you about further collection action. 

Common reasons for receiving a CP504 notice include: 

• Unpaid federal income taxes from a previous tax year. 

• An outstanding balance following an IRS examination or adjustment. 

• Penalties and interest added to an unpaid tax liability. 

• A payment that was missed, delayed, or not correctly credited to your account. 

Receiving the notice does not necessarily mean the IRS calculated your balance correctly. If you believe the amount is wrong or have already paid, review your account and contact the IRS using the information on the notice. 

Is a CP504 Notice a Final Notice of Intent to Levy? 

A standard CP504 notice is an official notice of intent to levy under Internal Revenue Code Section 6331(d). However, for most individual income tax liabilities, it is not the formal final notice that generally provides the right to request a CDP hearing before a levy on wages, bank accounts, or other property. 

The IRS prints “Final Notice” on the CP504, which can be confusing. It is the final balance due notice, but for most individual income tax debts it is not the notice that gives you the right to a hearing before the IRS levies your wages or bank account. That notice is usually Letter 1058 or Notice LT11, though some taxpayers receive Notice CP90 or CP297 instead. All of these are final notices of intent to levy that include hearing rights, and they typically come later. 

If the IRS does not receive payment within 30 days of the notice date, a CP504 notice can allow the IRS to levy an eligible state tax refund. In limited situations, it can also allow a levy for certain unpaid employment taxes or a levy on a federal contractor. A CP504 notice may also be followed by a later notice that provides formal hearing rights before broader collection action. 

There are exceptions to the general process. The IRS may levy before offering a hearing when collection is in jeopardy, when it levies a state tax refund, and in certain employment tax and federal contractor situations. In those cases, you can request a hearing after the levy. The exact consequences depend on the type of liability and the notice issued. 

You should not ignore a CP504 simply because another notice may follow. Responding early can help you understand your options and address the balance before the collection process advances. 

What Happens If You Ignore a CP504 Notice? 

Ignoring a CP504 notice can expose you to several financial consequences. The IRS may pursue an eligible state tax refund, continue adding applicable interest and penalties, and take additional collection steps if the tax liability remains unresolved. 

The IRS May Take Your State Tax Refund 

One of the most immediate consequences of ignoring a CP504 notice is the potential loss of your state income tax refund. The IRS may use the State Income Tax Levy Program to collect an eligible state tax refund and apply the money toward your unpaid federal tax liability. 

For example, imagine that you owe the IRS $5,000 and expect a $1,200 state income tax refund. If the IRS levies the refund, the money may be applied to your federal balance, reducing the amount you owe to $3,800 before accounting for any additional interest, penalties, or other payments. 

The amount collected depends on the refund available and the outstanding liability. If the refund does not cover the full balance, you may still owe the IRS money. 

Importantly, the state tax refund levy process differs from levies on wages and bank accounts. The IRS generally does not have to provide the same pre-levy CDP hearing opportunity before levying a state tax refund. If the IRS levies your state tax refund, it generally sends a notice afterward explaining your right to request a Collection Due Process hearing. You typically have 30 days from the date of that notice to make your request, so review it as soon as it arrives. 

Penalties and Interest May Continue to Increase 

Ignoring a CP504 notice does not freeze your tax liability. Interest and applicable penalties may continue to accrue while your balance remains unpaid, making it more expensive to resolve the account over time. 

A CP504 is also a notice of intent to levy, and that can make the failure to pay penalty more expensive. The penalty is usually 0.5% of the unpaid tax for each month or part of a month. If the tax is still unpaid 10 days after the IRS issues a notice of intent to levy, the rate increases to 1% per month. The penalty is capped at 25% of the unpaid tax, and it drops to 0.25% per month while an approved installment agreement is in effect, as long as you filed your return on time. 

The amount of additional charges depends on factors such as the original liability, how long it remains unpaid, and whether penalties apply. Paying only part of your balance may reduce the amount on which additional charges accrue, but it does not necessarily eliminate the remaining charges. 

For example, a taxpayer who owes $6,000 and waits several months to address the balance may owe more than the amount shown on the original CP504 notice. The precise increase depends on the applicable rates, penalties, and payment history. 

Review your current IRS account balance before making payment arrangements. The amount on an older notice may no longer reflect what you owe. 

The IRS May Send Another Notice Before Further Collection Action 

If you do not respond to a CP504 notice, the IRS may continue its collection process and send a subsequent notice of intent to levy that provides formal appeal rights. 

Common examples include Letter 1058 and Notice LT11, which generally notify taxpayers of the IRS’s intent to levy and explain their right to request a CDP hearing. 

A CDP hearing gives eligible taxpayers an opportunity to discuss collection alternatives, such as an installment agreement, and to raise certain disputes concerning the liability or proposed collection action. 

If you receive an LT11 or Letter 1058, pay close attention to the deadline. A timely CDP hearing request generally must be made within 30 days of the date of the notice. Missing that deadline limits your options. If you request a hearing late, but within one year of the notice date, you may still receive an equivalent hearing with IRS Appeals. However, an equivalent hearing does not stop the IRS from levying, and you cannot take the decision to U.S. Tax Court. 

Do not assume that you must wait for another notice before taking action. Contacting the IRS after receiving a CP504 may help you address the issue earlier. 

The IRS Could Levy Your Wages, Bank Accounts, or Other Assets 

If your tax liability remains unresolved, the IRS may eventually levy certain assets after satisfying the applicable legal and notice requirements. A levy is a legal action that allows the government to seize property or rights to property to collect unpaid taxes. 

Depending on the circumstances, property subject to levy may include: 

• Wages and other income: The IRS may require an employer or another party to send eligible payments toward your outstanding tax balance. 

• Bank accounts: The IRS may seize funds held in a bank account, subject to applicable procedures and protections. 

• Business assets: Certain business funds, accounts receivable, and other eligible assets may be subject to collection. 

• Certain Social Security benefits: Eligible benefits may be subject to federal tax levy under applicable rules. 

• Other personal property: Certain vehicles, real estate interests, and other assets may be subject to levy. 

For example, a taxpayer who ignores multiple collection notices and does not establish an acceptable payment arrangement may eventually face a levy on their bank account. This could leave them with less money available for rent, groceries, utilities, or other essential expenses. 

However, a standard CP504 notice alone does not generally authorize the IRS to immediately levy wages or bank accounts for an individual income tax liability. A separate formal notice and opportunity for a CDP hearing generally apply before those levies, subject to exceptions. 

The IRS May File a Notice of Federal Tax Lien 

Another potential consequence of leaving your tax liability unresolved is the filing of a Notice of Federal Tax Lien. 

A federal tax lien is the government’s legal claim against your property and rights to property because of unpaid taxes. The lien generally arises when the IRS assesses the tax, sends the required notice and demand for payment, and the taxpayer neglects or refuses to pay. A Notice of Federal Tax Lien is the public filing that alerts creditors to the government’s claim. 

A lien is different from a levy. A lien establishes a legal claim against property, while a levy involves the seizure of property or funds to satisfy the liability. 

A filed Notice of Federal Tax Lien can complicate financial transactions, including selling property or borrowing against certain assets. Although federal tax liens are no longer included on the major consumer credit reports, a lien can still create obstacles when dealing with creditors or prospective lenders.  

A CP504 notice does not automatically mean that a public Notice of Federal Tax Lien has been filed. Check your account and contact the IRS to understand the status of your particular case. 

The IRS May Certify Your Debt to the State Department 

Your CP504 notice also explains that unpaid tax debt can affect your passport. If your federal tax debt, including penalties and interest, is more than $66,000 for 2026, and the IRS has filed a lien or issued a levy and your hearing rights have run out, the IRS can certify the debt to the State Department. The State Department may then deny, refuse to renew, or revoke your passport. The IRS generally will not certify debt that is in currently not collectible status due to hardship or that has a pending installment agreement request. 

CP504 vs. LT11: What’s the Difference? 

A CP504 notice and an LT11 notice both concern unpaid tax liabilities, but they play different roles in the IRS collection process. Understanding the distinction helps you identify which deadlines and appeal rights apply to your situation. 

Feature	CP504 Notice	LT11 / Letter 1058
Primary purpose	Warns of further collection action and potential state tax refund levy	Provides formal notice of intent to levy and applicable hearing rights
State tax refund levy	Can support a levy on an eligible state tax refund (and, in limited cases, a levy for certain unpaid employment taxes or a levy on a federal contractor) if the balance is not paid within 30 days of the notice date	Not required before a state tax refund levy. This notice applies to levies on wages, bank accounts, and other property, which generally cannot begin until the hearing deadline has passed
CDP hearing rights	Does not, by itself, provide the formal CDP hearing rights associated with a final levy notice	Generally provides an opportunity to request a CDP hearing
Recommended response	Verify the balance and contact the IRS promptly	Follow the notice instructions and meet the hearing deadline if applicable

For most individual income tax liabilities, the IRS generally issues a separate formal notice before levying wages, bank accounts, or other property, subject to applicable exceptions. A CP504 should still be treated as an urgent collection warning because the IRS may take action against an eligible state tax refund. 

If you receive an LT11 or Letter 1058, review the deadline immediately. Missing the CDP hearing deadline can limit your procedural options. 

How Long Do You Have to Respond to a CP504 Notice? 

The deadline printed on your CP504 notice is important because it determines when the IRS may proceed with the collection action described in the letter. You should read the notice carefully rather than assuming that every IRS notice follows the same timeline. 

Understanding the CP504’s 30-Day Deadline 

A standard CP504 notice generally gives you 30 days from the date printed on the notice to pay the outstanding balance. If the IRS does not receive payment within that time, it can levy an eligible state tax refund. In limited situations, it can also serve a levy for certain unpaid employment taxes or a levy on a federal contractor. The 30 days start on the notice date, not the day the letter arrives, so act quickly. Certain specialized CP504 notices can have different implications, and other collection rules may apply to your situation, so read the exact notice you received carefully. 

If you cannot pay the full balance within the specified period, contact the IRS promptly to discuss payment arrangements or other available options. Acting before the deadline may help you avoid unnecessary complications. 

What If the CP504 Deadline Has Already Passed? 

Missing the CP504 deadline does not necessarily mean the IRS has already taken your refund or that you have lost every opportunity to resolve your tax liability. 

Start by reviewing your current IRS account and checking whether the state refund levy has occurred. Then determine whether the IRS has issued another collection notice or whether a payment arrangement is available. 

For example, if your CP504 deadline passed two weeks ago but the IRS has not yet taken further action, you may still be able to contact the agency and arrange to pay your balance over time if you qualify. 

Do not delay simply because the deadline has passed. If you have received a later notice that provides hearing rights, follow its instructions and deadlines carefully. 

What Should You Do If You Receive a CP504 Notice? 

If you receive a CP504 notice, the most effective response is to verify the liability and determine which resolution option fits your financial situation. You do not necessarily need to pay the entire balance immediately to begin addressing the problem. 

Review the Notice and Verify Your Tax Balance 

Begin by checking the notice date, tax year, amount due, payment deadline, and instructions for contacting the IRS. Compare the information with your tax returns, payment records, and current IRS account balance. 

If the amount seems incorrect, gather documentation before contacting the IRS. Useful records may include: 

• Copies of relevant federal tax returns. 

• Bank statements or canceled checks showing tax payments. 

• IRS payment confirmations. 

• Previous IRS notices and correspondence. 

• Documents supporting a requested correction or adjustment. 

If you already paid the amount listed, contact the IRS to confirm that the payment was credited correctly. Payments can take time to appear in your account, so keep your confirmation records until the issue is resolved. 

Pay the Full Amount If You Can Afford To 

If you agree with the balance and have sufficient funds, paying the full amount is generally the most direct way to resolve the outstanding liability covered by the notice. 

Follow the payment instructions on the CP504 notice or use an official IRS payment method. Make sure you apply the payment to the correct tax year and tax type. 

After paying, verify that the payment has posted and check whether any additional interest, penalties, or other balances remain. If you receive another notice after paying, do not automatically assume the payment failed. Review your account and contact the IRS if the balance still appears incorrect. 

Set Up an IRS Payment Plan 

If you cannot afford to pay the full balance at once, you may qualify for an IRS installment agreement. An installment agreement allows eligible taxpayers to pay their outstanding tax liability through scheduled payments over time. 

The IRS offers different payment arrangements depending on the amount owed, the taxpayer’s financial circumstances, and other eligibility requirements. Some taxpayers may be able to apply online, while others may need to submit additional information. 

For example, a taxpayer who owes $7,500 but can afford to pay $300 per month may want to explore an installment agreement instead of allowing the balance to remain unresolved. 

Applying for a payment plan is not the same as receiving approval, so keep following the instructions on any notices you receive. In general, though, the IRS cannot levy your property while it is processing a complete installment agreement request, for 30 days after a rejection, or while a timely appeal of that rejection is pending. This protection does not stop interest and penalties from accruing, and the IRS may still file a Notice of Federal Tax Lien. 

Explore Other Tax Relief Options 

An installment agreement is not the only potential solution for an unpaid tax liability. Depending on your financial circumstances and eligibility, you may qualify for another IRS collection alternative. 

An offer in compromise allows eligible taxpayers to settle their tax liability for less than the full amount owed when the IRS determines that the applicable requirements are met. Approval depends on factors such as your ability to pay, income, expenses, asset equity, and other circumstances. 

If paying the tax liability would prevent you from meeting basic living expenses, you may qualify for currently not collectible (CNC) status. The IRS may temporarily delay collection when it determines that you cannot afford to pay. However, interest and penalties generally continue to accrue, and the IRS may review your financial situation again later. 

Other possibilities may include requesting penalty relief if you qualify or exploring whether the underlying liability can be challenged through an appropriate procedure. 

No single option works for everyone. Review the eligibility requirements and consider seeking qualified tax assistance if you are uncertain which approach is appropriate. 

Dispute the Balance if You Believe the Notice Is Incorrect 

If you believe the CP504 notice reflects an incorrect balance, do not ignore it. Contact the IRS using the phone number on the notice and explain the discrepancy. 

For example, you may have already paid the balance, received an adjustment that was not reflected in the notice, or identified an error in the tax assessment. Provide supporting documents and follow the IRS’s instructions for resolving the issue. 

If you disagree with the underlying tax liability, the appropriate procedure depends on how the liability arose and whether you previously had an opportunity to dispute it. A CP504 does not, by itself, provide the same CDP hearing rights as a formal final notice of intent to levy. 

If you disagree with the IRS’s plan to levy, you can ask for a Collection Appeals Program (CAP) review before collection action takes place. Start by calling the number on your notice and asking to speak with a Collection manager. If you and the manager cannot reach an agreement, you can then ask the IRS Independent Office of Appeals to review your case by submitting Form 9423, Collection Appeals Request. The window to submit the form is short, so ask the IRS how much time you have. If the matter is complicated or a deadline is approaching, consider consulting a qualified tax professional. 

Can You Stop IRS Collection Actions After Ignoring a CP504? 

Ignoring a CP504 notice can make your tax situation more difficult, but you may still have options to resolve the balance and address collection activity. The available remedies depend on your account status, the type of tax liability, and whether the IRS has already taken action. 

Contact the IRS to Discuss Your Options 

The first step is to contact the IRS using the information on your notice. Ask for an explanation of your current balance, whether a state tax refund levy has occurred, and whether additional collection notices have been issued. 

If you cannot pay the full amount, explain your circumstances and ask which payment arrangements or collection alternatives may be available. 

If you have already established an installment agreement, verify that it is approved and that your account reflects the arrangement. If you submitted a payment or application recently, keep proof of the transaction and ask whether any further steps are required. 

Understand Your Collection Appeal Rights 

Taxpayers have specific rights when challenging certain IRS collection actions, but the deadlines and procedures depend on the notice received. 

A formal notice of intent to levy, such as LT11 or Letter 1058, generally gives eligible taxpayers 30 days to request a CDP hearing. A timely request may allow the taxpayer to discuss collection alternatives and raise certain issues concerning the liability or proposed collection action. 

The Collection Appeals Program (CAP) is a separate option. Your CP504 notice explains that you can request a CAP review of the proposed levy before collection action takes place. CAP and CDP are different processes. For example, a CAP decision generally cannot be taken to U.S. Tax Court, while a timely CDP hearing request preserves that right. 

Because a standard CP504 does not, by itself, provide the formal CDP hearing rights associated with a final levy notice, do not assume that a CP504 alone gives you the same appeal options. Review the instructions on your notice and seek qualified assistance if you are unsure how to proceed. 

Consider Professional Tax Relief Assistance 

If your tax situation involves a substantial balance, multiple tax years, disputed assessments, or potential levies, professional assistance may help you understand the collection process and evaluate your options. 

A qualified tax professional may review your IRS account, assess your eligibility for payment arrangements or other resolution options, help prepare relevant financial documentation, and communicate with the IRS when properly authorized. 

Professional representation does not guarantee that the IRS will approve a particular resolution or stop collection activity. However, getting help early may make it easier to understand your obligations and respond appropriately to deadlines.

Frequently Asked Questions 

What Happens If You Ignore a CP504 Notice? 

If you ignore a CP504 notice, the IRS may levy an eligible state tax refund and continue collection efforts. If the balance remains unpaid, the IRS may pursue additional collection action, including levies on wages or bank accounts after applicable legal and notice requirements are met. 

Is a CP504 Notice a Final Notice Before Wage Garnishment? 

A standard CP504 notice is generally not the formal final notice that provides the right to a CDP hearing before the IRS levies wages or bank accounts for an individual income tax liability. A separate notice of intent to levy and hearing rights is generally required, subject to exceptions. 

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

Yes. Eligible taxpayers may be able to establish an IRS installment agreement after receiving a CP504 notice. Approval depends on your circumstances. In general, the IRS cannot levy your property while it is processing a complete request, but you should still confirm the status of your application and keep following the instructions on any notices you receive.
