IRS LT11 vs. CP504: What Each Notice Means and What to Do Next

Receiving an IRS notice can feel overwhelming, especially when the letter uses formal language and warns about collection action. Two notices that often cause confusion are CP504 and LT11 or letter 1058, and while they are related, they are not the same thing. The CP504 is an IRS notice telling you that the agency intends to levy your state tax refund and may escalate collection if you do not act, while LT11 is the final notice of intent to levy and the notice that gives you the right to request a Collection Due Process hearing.

For taxpayers, the most important point is simple: both notices should be treated seriously, but LT11 usually means the situation has moved into a more urgent phase because it is the final pre-levy notice that can trigger your hearing rights. If you live in Whittier, Los Angeles, or anywhere in California and want a calm, practical approach to resolving the issue, Mike Habib, EA can help review the notice, explain the options, and work toward a flat-fee resolution strategy that fits your case. 

Why These Notices Matter

IRS collection notices are not sent randomly. They typically follow earlier balance-due notices, and they show that the IRS believes the account still has an unpaid tax debt. The goal of both CP504 and LT11 or letter 1058 is to pressure the taxpayer to respond before the IRS uses stronger collection tools such as levies, garnishments, or seizures of property or rights to property. 

A notice does not automatically mean the IRS has already taken money from you. It means the agency is warning that collection action may happen if you do not pay, dispute, or otherwise address the debt. That distinction matters because many taxpayers assume the notice is the final act, when in reality it is often the last chance to act before the IRS moves forward. 

CP504 Explained

CP504 is generally understood as a serious collection notice that tells you the IRS intends to levy your state tax refund if you do not act. In plain language, the IRS is saying you still owe a balance, earlier reminders have not solved the problem, and the agency may take your state refund as part of collection. 

The IRS notice page says the CP504 is a final reminder that the IRS intends to levy wages, bank accounts, or a state tax refund because an unpaid balance remains. That said, the practical impact most taxpayers notice first is the threat to the state refund, which is why this letter often creates confusion and panic. 

A CP504 is important, but it is not the same as the final CDP notice that gives you levy-hearing rights. It is more like an escalation warning in the collection process, and it often arrives after prior notices such as CP14, CP501, and CP503. 

LT11 Explained

LT11, also known as Letter 1058, is the IRS Final Notice of Intent to Levy. This is the notice that tells you the IRS intends to seize property or rights to property if the tax debt is not resolved. 

This notice is especially important because it typically starts the 30-day period to request a Collection Due Process hearing by filing Form 12153. That hearing request can be a critical taxpayer right, because it may allow you to challenge the collection action and discuss alternatives before a levy is carried out. 

The IRS states plainly that once you receive LT11 or Letter 1058, you should contact them immediately. In practical terms, this is the notice that often calls for fast, organized action rather than waiting to see what happens next. 

Main Differences

The easiest way to think about the two notices is that CP504 warns, while LT11 finalizes the levy warning and opens hearing rights. CP504 commonly focuses on the state refund and collection escalation, while LT11 is the formal final notice of intent to levy with the right to seek a CDP hearing.

Here is a simple breakdown:

For taxpayers, the most useful takeaway is not the label itself, but the stage of collection. CP504 means the account is already in serious collection status, while LT11 means the IRS is at the final step before levy unless the taxpayer responds or resolves the matter. 

What the IRS Can Do Next

After a CP504 or LT11, the IRS may move toward stronger collection enforcement if the debt remains unresolved. That can include levy-related action, wage garnishment, bank account seizure, or taking a state tax refund, depending on the situation and the IRS’s collection posture. 

A lot of taxpayers worry that one notice automatically means everything will be taken immediately. In reality, collection actions usually depend on timing, account status, response history, and whether the taxpayer takes action before the deadline. That is why getting ahead of the notice is far better than waiting until an account is frozen or a refund disappears. 

What To Do First

The best first step is to read the notice carefully and identify the tax year, balance, deadline, and contact information. Then confirm whether the balance looks correct and whether you actually received earlier IRS notices that led up to this one. 

If the amount is wrong, or if you already paid, gather proof right away and be ready to respond in writing or through the IRS contact instructions on the notice. If the amount is correct, you still have options such as paying in full, requesting a payment plan, asking about hardship relief, or pursuing a hearing where eligible. 

Payment Options

If you can pay the balance in full, that usually stops the collection spiral faster and prevents more penalties and interest from building. If you cannot pay in full, the IRS says taxpayers may request a payment plan, and common tools include Form 9465 or, in some cases, related payment agreement forms. 

An installment agreement can be useful when the balance is real but the taxpayer cannot absorb it all at once. The key is to be realistic about what you can afford, because a plan that is too aggressive may break down later and create more stress than it solves.

A professional review can also help determine whether a payment plan, partial payment strategy, or another resolution path is more appropriate for your facts. This is one reason taxpayers often prefer a structured, flat-fee consultation rather than paying by the hour while trying to figure out the next move. 

Hearing Rights

LT11 or letter 1058 matters because it generally carries the right to request a Collection Due Process hearing by filing Form 12153 within 30 days. That deadline is important because missing it can reduce your options and may force you into a narrower process later.

A CDP hearing can be valuable when the taxpayer wants to challenge the levy action, discuss collection alternatives, or raise concerns about the amount, compliance status, or procedural issues. The IRS instructions for Form 12153 say it should be sent to the address for requesting a hearing shown on the CDP notice, not the payment address.

This is one of the biggest mistakes taxpayers make: sending the form to the wrong place or waiting too long. On a deadline-driven notice, small administrative errors can become expensive problems. 

When Hardship Matters

Not every taxpayer who receives an IRS notice is unwilling to pay. Some simply cannot pay without losing the ability to cover basic living costs, rent, medication, or payroll obligations. In those situations, a hardship-based approach may be worth exploring, including whether the account could qualify for a currently not collectible status or another relief path. 

The IRS notice materials and related guidance make clear that taxpayers should respond if they cannot pay the full amount and may need to ask for time or an arrangement that matches their financial reality. The most important part is to present the case accurately and with supporting documents, not guesswork or emotional statements. 

Common Mistakes

One common mistake is ignoring CP504 because it is not the final notice. That thinking is risky, because the notice is still a serious collection warning and may be the first visible sign that the IRS is preparing stronger action. 

Another mistake is assuming LT11 is just another reminder and not a deadline-driven legal notice. LT11 is different because it usually starts the 30-day CDP hearing period, which is a meaningful procedural right. 

A third mistake is trying to solve the problem without first confirming whether all tax returns are filed and whether the IRS account matches the taxpayer’s records. Payment plans and other resolution options can become much harder if the underlying filing picture is incomplete. 

How Mike Habib, EA Helps

Mike Habib, EA helps taxpayers in Whittier, Los Angeles, and surrounding areas deal with IRS notices in a practical, client-focused way. For a CP504 or LT11 matter, that usually starts with reviewing the notice, identifying the deadline, checking the balance, and determining the most efficient resolution path. 

The value for the taxpayer is straightforward: less confusion, faster clarity, and a process that is focused on resolution rather than billing by the hour. That flat-fee approach can be especially helpful when a taxpayer wants to know the cost up front before moving forward. 

Mike Habib’s firm also fits well for taxpayers who want a more hands-on explanation of their options, including payment plans, hearing requests, and next-step strategy. In a notice-driven situation, the right help is usually the help that turns the letter into a clear action plan. 

What a Taxpayer Can Expect

A strong notice review usually begins with the IRS letter itself, because the exact wording matters. From there, the next steps may include evaluating whether the taxpayer agrees with the debt, whether payment is possible, whether a hearing request is needed, and whether financial documentation is required.

When Mike Habib, EA works with a taxpayer, the goal is not to drown the client in jargon. The goal is to explain what the notice means in plain English, map out the next action, and keep the matter organized so deadlines are not missed. That kind of clarity is especially useful when the IRS language feels intimidating and the client needs an informed, steady response.

How To Respond Fast

If you have CP504, act as though the account is already in a serious collection stage. If you have LT11 or letter 1058, treat it as an immediate deadline notice and pay close attention to the 30-day hearing window. 

A practical response sequence looks like this:

1. Identify the notice type and the tax year involved. 
2. Confirm whether the balance is correct and whether prior notices were received. 
3. Decide whether to pay, request a payment plan, request relief, or contest the collection action. 
4. If LT11 applies and you want hearing rights, prepare Form 12153 quickly and send it to the correct address. 
5. Keep copies of every document and every deadline-related action. 

This is one of those situations where speed and organization matter more than overthinking. The IRS notices are designed to force a response, so the taxpayer’s best move is to respond with facts, documentation, and a clear plan. 

What Happens If You Ignore It

Ignoring either notice usually makes the problem harder, not easier. With CP504, the IRS may move forward with levying your state tax refund and may also continue collection activity on the balance due if nothing changes.

With LT11 or letter 1058, ignoring the notice is even riskier because it is the final notice of intent to levy and normally gives you only 30 days to request a Collection Due Process hearing. If you miss that window, the IRS can generally proceed with levy action without giving you another chance to request that specific hearing right.

In practical terms, the consequences can include wage levies, bank account levies, state tax refund seizure, and the filing of a Notice of Federal Tax Lien. A federal tax lien can make it harder to sell property, borrow against assets, or keep credit opportunities intact.

For business owners, ignoring the notices can be even more disruptive because the IRS may pursue business assets, accounts receivable, and other property tied to the company. That is why taxpayers should never treat these notices as paperwork to set aside for later; the deadlines are part of the notice itself.

Documents to Gather

The best response starts with organized records. Before you call the IRS or speak with a tax professional, gather the notice itself, prior IRS letters, and any records that show what you already paid or why the balance may be wrong.

Helpful documents include:

• The CP504 or LT11 notice itself.
• Prior IRS notices, if any.
• Copies of filed tax returns for the years involved.
• Proof of payment, such as cancelled checks, bank confirmations, or IRS transcript entries.
• Any amended returns or supporting documents that affect the amount due.
• Recent pay stubs or income records.
• Business financial records, if the debt relates to a business account.
• Bank statements and asset information if a payment plan or hardship review may be needed.

If you are requesting a CDP hearing, the IRS Form 12153 instructions say to include a copy of the CDP notice and send the form to the hearing-request address shown on the notice, not the payment address. If you want the IRS to consider collection alternatives, Appeals may also need a financial statement such as Form 433-A or Form 433-B, depending on the situation.

The more complete your file is, the faster your case can move from panic to resolution. In notice cases, missing paperwork is one of the most common reasons taxpayers lose time they cannot afford to lose.

CP504 vs. LT11 Timeline

The simplest way to understand the two notices is to see them in sequence. The IRS usually starts with an unpaid balance notice, then sends reminder notices, then escalates to CP504, and later to LT11 if the debt still has not been resolved.

Here is a practical timeline:

1. CP14 — Initial notice that you owe unpaid taxes.
2. CP501 — First reminder notice.
3. CP503 — Second reminder notice.
4. CP504 — Intent-to-levy warning, often focused on the state tax refund.
5. LT11 / Letter 1058 — Final Notice of Intent to Levy and Notice of Your Right to a Hearing.

What matters most is that CP504 is serious, but LT11 is the notice that usually creates the most immediate procedural urgency because of the 30-day hearing window. CP504 is often the warning that the account is moving toward collection enforcement, while LT11 is the final step before levy action unless the taxpayer responds.

This timeline also helps taxpayers understand why waiting after the first notice can create a chain reaction. Once the IRS keeps sending escalating notices, each missed response can narrow the taxpayer’s options and increase pressure.
