What Happens After You Receive an IRS Tax Notice? A Step-by-Step Guide to CP14, CP504, LT Notices, Levies and Appeals

An IRS tax notice may cause anxiety, particularly if it mentions you have an unpaid balance, IRS collection action, a levy, or that you can appeal. Don’t ignore it is the most important thing. In a notice from the IRS, you will typically find a statement about what it is that the IRS thinks is incorrect, how much they think it is, what you will need to do, and when it will be due.

The different notices have varying effects. A CP14 will typically initiate the balance-due collection process, and a CP504 will be a more urgent collection notice. Letters can be issued that formalize a warning of a proposed levy and give rights to a Collection Due Process hearing, for example, LT11 or Letter 1058.

The notice and the impact of not taking action could be detrimental to your options.

Step 1: Read the IRS Notice Carefully

The first thing is to find out what the IRS wants you to do.

Look for:

  • Notice/letter number.
  • Tax year involved.
  • Fill out the amount owed to the IRS.
  • Payment deadline.
  • The reason for the notice.
  • Available payment options.
  • Right of appeal or hearing.
  • IRS Mailing address and telephone number.
  • Guidance on how to submit documents.

When a response is required, the IRS suggests keeping the notice with your tax records and filing the response by the deadline. If you disagree, please follow the instructions for a dispute in the notice and provide supporting information and documentation.

It’s important to note that the seriousness of a notice is not always apparent by its appearance. The notice number and the language regarding collection/appeal rights are more significant.

Step 2: Know What a CP14 Notice Is

A CP14 is typically a first balance due notice. It indicates that the IRS thinks you owe federal taxes and is asking you to pay them.

This notice provides details on the amount due and how it will be collected. If you can’t pay in full, you might be able to request a payment plan with the IRS, such as an installment agreement. It is also important to note that if you disagree with the balance, contact the IRS.

After CP14, What Should You Do?

  1. Check for the tax year and balance.
  2. Check this against your income tax and payment records.
  3. Check your IRS Online Account for account and payment information.
  4. Decide if you can make full payment.
  5. If that isn’t possible, find out about the option to pay.
  6. If the balance looks wrong, get in touch with the IRS right away.

Usually, interest will start to accrue on the unpaid balance, and penalties may also be charged.

What Do You Do If You Already Paid?

Don’t automatically pay the same amount again. Review to see if payment has been deposited into your IRS account and collect documentation of the payment. Sometimes, a notice is sent before the IRS account has been updated due to payment-processing delays.

Step 3: Is a CP504 Notice Serious?

A CP504 is an urgent item that needs to be taken care of. This is an IRS notice regarding an unpaid balance and collection action.

If the balance is not paid, the IRS will initiate income, bank account, property, or state tax refund collection actions for a CP504.

But there’s a big catch:

Just because you have a CP504 does not mean that the IRS can take your property immediately. In the ordinary collection process, the IRS must send a formal Notice of Intent to Levy and a Notice of Your Right to a Hearing before a levy can be issued, the IRS Independent Office of Appeals states.

This does not imply you should wait.

In the Event That You Get CP504:

  • Check the balance right away.
  • Pay it if you can.
  • If you are unable to pay in full, think about making a payment arrangement.
  • If you think the balance is incorrect, contact the IRS.
  • Examine if you have Appeal or Collection Appeals Program rights.
  • Save all receipts and correspondence.

Step 4: Understand LT11 and Letter 1058

LT11 and Letter 1058 are far more serious collection communications, as they can be considered a Final Notice of Intent to Levy and Notice of Your Right to a Hearing.

The IRS has indicated that tax filers will have 30 days from the date of each letter to file a request for a Collection Due Process hearing, using Form 12153, and sending it to the address listed on the notice.

This is a priority deadline.

Without payment or a resolution, the IRS will take collection action against wages, bank accounts, some income, and other property or property rights. The Internal Revenue Service (IRS) can also place a federal tax lien.

Note: Be Careful Not to Go by The Wrong Name; A Levy Is Not A Lien

Tax liens typically represent the government’s legal claim on property for unpaid taxes.

A levy is a real attachment of rights or property to meet the debt.

They are distinct collection devices and can have distinct procedures and outcomes.

Step 5: Decide If You Can Resolve the Issue or Pay the Fee

Not all the time does everyone who receives an IRS collection notice require an appeal. Sometimes the appropriate solution is simply resolving the balance.

Possible solutions may include:

  • Full payment.
  • Installment agreement.
  • If eligible, offer in Compromise.
  • Financial hardship – delay of collection temporarily.
  • Other procedures for collecting provided by the IRS.

The IRS has written instructions for taxpayers who are unable to pay the balance on a CP14 in full to consider payment-plan options.

Be careful; do not select the first payment option offered. Analyze the balance, income, expenses, assets, and long-term sustainability.

Step 6: Can IRS Collection Action Be Appealed?

Yes, some decisions about IRS collections may be appealed.

Collection Due Process (CDP) hearing with the IRS Independent Office of Appeals is one important process.

CDP rights may arise after specific notices, which take into account:

  • Federal tax liens.
  • Final notices to pay taxes.
  • Jeopardy levies.
  • Certain state tax refund levies.
  • Certain post-levy situations.

A timely request for a CDP is usually within 30 days of the date of the applicable notice. Form 12153 is the usual form used.

An early request for a CDP can be a chance to discuss other ways to collect and, if applicable, challenge the liability, as the taxpayer has not had a prior chance to do so. It can also serve as a means to obtain judicial review in the Tax Court of the Appeals determination.

Step 7: Know about the Collection Appeals Program

There is also a procedure you can use to challenge some IRS collection actions, called the Collection Appeals Program (CAP).

CAP can cover issues relating to:

  • Liens
  • Levies
  • Seizures
  • Decline or changes of some installment plans
  • The termination and/or proposed termination of certain installment agreements
  • Some property decisions relating to collections

A specific notice will specify the availability and how to request CAP. The IRS has identified CAP as the appeal route for some CP504 cases.

CDP vs. CAP

These procedures do not necessarily have to be considered interchangeable.

There are judicial review rights available at a timely CDP hearing, and CAP does not generally afford the same manner of review to the Tax Court.

Note: Be sure to read the notice thoroughly and know the rights that each appeal route offers.

Step 8: Collect Evidence before you contact the IRS

If you think the IRS balance is wrong, don’t take the word of the IRS.

Collect data including:

  • Copies of tax returns.
  • IRS notices.
  • Proof of payments.
  • Cancelled checks.
  • Bank statements.
  • Forms W-2 and 1099.
  • Amended returns.
  • Receipts and invoices.
  • Accounting records.
  • Deductions and/or credits supported by documentation.
  • Communication with IRS.
  • Evidence related to identity/filing issues.

The IRS states that it particularly likes to have pertinent documents present during its interaction with someone who is in disagreement with a balance owed.

Keep Your Evidence Clear and Easily Understood

Don’t send a huge mass of documents; make a brief explanation:

Proceeding: IRS claims that $20,000 is owed.

Taxpayer position: paid $20,000.

Evidence: Bank statement and payment confirmation that includes a transaction.

Action requested: Put the payment into the right tax period and adjust the balance.

This helps to link the evidence to the issue.

Step 9: We'll discuss the consequences of failing to respond to an IRS notice

Failure to respond to an IRS notice doesn’t resolve the issue.

If the non-response persists, the consequences may be:

  • Additional penalties and interest.
  • A federal tax lien.
  • Levy action.
  • Confiscation of some property or property rights.
  • Collection notices that provide less and/or alternative options for the procedure.
  • Loss of an opportunity to use a particular appeal procedure within its deadline.

In fact, if you don’t reply to IRS letter # LT11 or Letter 1058, they may initiate levy action and even place a federal tax lien.

This is why it’s important for even those who can’t afford to pay to generally respond instead of being silent as a taxpayer.

Step 10, You Will Be Preparing for an IRS Appeals Conference

If your case is eligible for an Appeals process, hypothesis on the issue with which you disagree.

The general outline of your presentation should include the following:

  1. The IRS final decision.
  2. Why you disagree.
  3. What evidence do you have to back up your argument?
  4. Which documents contain evidence of these facts?
  5. What resolution are you requesting?

Don’t use ambiguous phrases like, “The IRS is incorrect. But state specifically what portion of your account or collection action is being challenged.

The IRS Independent Office of Appeals is meant to offer a tax dispute resolution mechanism for cases that can be solved without the need for a lawsuit.

Practical Tips After Receiving an IRS Notice

  1. Calendar every deadline

Record the answer date right away. The notice period for CDP notices or for some other appeals is as short as 30 days.

  1. Do not alter the original notice

Don’t throw away the notice after scanning it. Keep the complete document and envelope with your tax records.

  1. Check the Tax period

IRS notices may include various tax years. Ensure that the required payments or documentation are applied to the right period.

  1. Never assume that the appeal was preserved by calling it

If this is a notice for a formal response, adhere to the procedure specified. A phone call may not be a substitute for a timely written appeal/hearing request.

  1. Avoid placing a levy when one is needed

If you have financial difficulties, please contact the IRS before collection action begins. If you take action earlier, you will have more opportunities to discuss options for resolution of the incident.

  1. Consider professional representation

If there’s a large amount of debt, several tax years are involved, a tax levy is looming in the horizon, or the case has complex legal or financial matters, a tax attorney, CPA, or enrolled agent can assist.

  1. Keep communication records

If dates, names, or identification information are provided, record dates, names, or information of the conversations, and any follow-up requested. Make copies of IRS documents.

A simple IRS notice action plan

Use this checklist when you receive an IRS notice:

Read → Verify → Calendar → Respond → Document → Resolve

Read: Be able to interpret the meaning of the notice.

Verify: Ensure that the tax year, balance, payments, and underlying records are correct.

Record the response and appeal deadlines on the calendar.

Respond: Pay, contest, offer an arrangement, or follow the appropriate appeal procedures.

Document: Maintain records of payments, correspondence, submissions, and deliveries.

Resolve: Ensure the account is followed until it reflects the agreed/corrected outcome.

Tax notices from the IRS do not indicate that you can’t save your situation. It’s a message from the IRS and what they expect you to do.

A CP14 usually indicates unpaid debt and will prompt you to pay or defend the debt. A CP504 is a higher-priority collection warning. A formal final warning before the levy and critical CDP hearing rights can be given by LT11 and Letter 1058. Appeals may be different for other notices.

The key is to follow the directions of the individual IRS notice, not assuming that all of them are processed the same way. See if there is a balance, review records, check a due date, consider payment as an alternative to collection, reconsideration, CAP, or a CDP hearing.

In the case of an Appeal, time is important. A timely and well-supported response can help to maintain procedural rights and provide you the chance to state the facts and evidence to support your position.
