What to Do When You Receive Certified Mail From the IRS

Why Did I Get a Certified Letter from the IRS?

The IRS sends its most serious notices through certified mail, and ignoring these letters will not protect you. Certified mail from the IRS typically threatens actions like wage garnishments, asset seizures, tax assessments, or criminal exposure. Whether you open the letter or not, the IRS will move forward if you don’t respond by the deadline.

Key Takeaways:

• Certified mail creates legal proof of notice – even if you refuse the letter or throw it away, the IRS has met its legal obligation to notify you.
• Refusing to sign does not stop the IRS process – legally, the IRS only has to send the letter to your last known address; it doesn’t matter if you actually receive it or not.
• Most letters provide 30–90 days to respond – these deadlines are firm, and missing them puts you at risk.
• Common notices include levy, lien, and deficiency letters – the IRS only uses certified mail for serious matters.

What If You Don't Pick Up Certified Mail From the IRS?

Unfortunately, ignoring IRS letters will not make the issue disappear. In fact, it usually makes things worse.

• The IRS can proceed even if you don’t pick up the letter – this issue has gone to court many times, and the courts have repeatedly ruled that sending a notice to the taxpayer’s last known address meets the legal requirement to notify taxpayers before the IRS takes certain actions.
• Deadlines are based on mailing dates – your response deadline is based on when the IRS sent the notice. You don’t get extra time if you refuse to sign for the letter or pretend it didn’t come.
• Ignoring the notice can increase your enforcement risk – the IRS has a lot of options to help people who are behind on back taxes, but only if the taxpayer is willing to resolve the issue. You put yourself at risk if you refuse to cooperate.

Why Does the IRS Send Certified Letters?

The IRS uses certified mail to get legal proof of receipt, to meet legal requirements, and to start the time clock to the deadline. The IRS also uses certified mail to catch taxpayers’ attention.

1. Certified mail = Legal proof of receipt

When the IRS sends a letter via certified mail, they’re creating a paper trail. This is especially important when the notice they’re sending has legal weight. For example, when they’re giving you a final warning or a deadline that affects your rights, they want to be able to prove:

• The notice was sent
• It was received
• The clock has started on whatever time-sensitive action they mentioned

2. Taxpayers are more likely to notice certified letters

That’s why certified letters are often used for serious matters, but again, that doesn’t mean it’s already too late or that you’re automatically in deep trouble. In most cases, you have a limited amount of time to take action, and that’s all outlined in the letter. But the IRS wants you to notice and respond to this letter.

The IRS sends quite a few types of letters and notices using certified mail. These letters and notices are typically important and need to be dealt with as soon as possible.

3. The IRS wants to start a countdown to a deadline

Because using certified mail means that the IRS has proof of when the letter was sent, that means they are able to start the countdown of when their next action can take place. Some types of IRS communication are actually required to be sent by certified mail because it’s written into the tax code.

What Does a Certified Letter From the IRS Mean?

Usually, it means that the IRS plans to take a serious collection action, such as garnishing wages or seizing assets. It may also signify that the IRS has proposed a tax or plans to assess a Trust Fund Recovery Penalty (TFRP) against you.

Letter Number	What it says	Usual response deadline
LT11	IRS intends to seize wages or other assets	30 days
LT1058	IRS intends to seize wages or other assets	30 days
CP90	IRS plans to garnish Social Security payments	30 days
LT3172	IRS has filed a federal tax lien	30 days
LT3219	IRS is proposing a tax assessment	90 days (150 days if sent out of the country)
LT1153	IRS is proposing a TFRP against you	60 days (75 days if sent out of the country)

Here are a few of the most common IRS notices that come through certified mail:

LT11 / Letter 1058 – Final Notice of Intent to Levy

These final intent to levy notices warn that the IRS plans to start seizing assets like bank accounts, wages, or property. You have 30 days to appeal, but if you don’t respond, the IRS can move forward. Typically, they start with wage garnishments or bank levies, rather than seizing physical assets.

CP90 – Final Notice Before Levy on Social Security

Similar to LT11, but more specific, this letter says the IRS plans to levy your Social Security benefits to pay off a tax debt. The IRS can take up to 15% of your payment with an automated levy, and potentially even more with a manual levy initiated by a revenue officer.

Letter 3172 – Notice of Federal Tax Lien Filing

This means the IRS has filed a tax lien against you, which is a legal claim on your property due to unpaid taxes. It affects your ability to sell or refinance property, but it doesn’t mean your stuff is being taken yet. The IRS must send other notices before seizing assets or wages.

Letter LT36 – Demand for payment from federal employees and retirees

This means the IRS believes a federal employee owes a tax debt. They send an LT36 letter to demand payment, but at this point, you don’t have to worry about seizures or garnishments.

Letter 3219 – Notice of Deficiency

This letter says the IRS plans to assess additional taxes unless you respond within 90 days. It may come after the IRS audits your return, adjusts your return, or calculates your tax due for a year you didn’t file using a substitute for return. If you don’t respond, the IRS will assess the proposed tax and can then start collections.

Letter 1153 – TFRP Proposed Assessment

The IRS sends this letter if it plans to assess a Trust Fund Recovery Penalty against you as an individual for a business’s unpaid payroll taxes. You must respond within the 60-day appeal window, or the agency will move forward with the assessment. This penalty is incredibly serious because it cannot be discharged in bankruptcy, and the IRS will pursue your personal assets to collect it.

I Haven’t Opened the Letter Yet. Why Did I Receive It?

If you haven’t opened your certified letter yet, or you just saw the USPS slip saying something’s waiting for you, here are a few questions to help you narrow down what it could be.

1. Have you missed any tax payments?

If you know you owe back taxes, especially from prior years, there’s a good chance this is a collection notice. The IRS doesn’t go straight to certified letters, but they do after they’ve sent a few regular ones. Possible certified letters in this case include LT11, CP90, and Letter 1058.

2. Were you recently audited — or do you suspect the IRS changed your return?

If you received a notice a while ago about discrepancies on your tax return or about an audit and you didn’t respond, or thought it was resolved, this could be the IRS’s next step. Possible letters include Letter 3219, Notice CP2000, or a notice of assessment.

3. Are you self-employed or running a small business?

If you’re self-employed or own a small business, your taxes are more complex and more likely to be under review. You might also be dealing with 941 payroll tax issues or estimated tax problems. If you’ve missed deadlines or payments, the IRS may be warning of collection actions.

4. Have you recently moved or changed addresses?

The IRS might have been sending notices to your old address, and now they’re using certified mail to get your attention. If you’re seeing a certified letter without any earlier warnings, this could be why.

When Should You Be Worried?

Unfortunately, most certified letters from the IRS mean you’re at a serious point in the process. So let’s talk about red flags that mean it’s time to get help now.

The letter mentions “levy,” “lien,” or “seizure.”

These aren’t threats to ignore. They mean the IRS has already gone through earlier steps and is now preparing to take your wages, bank funds, or file a lien against your property. Don’t wait. You still have options, but the clock is ticking.

You owe more than $10,000

Once your tax debt hits $10,000, the IRS may escalate collection efforts faster. They may refer your case to a private debt collector, file tax liens, or start involuntary collections.

You’re getting certified mail, and didn’t know you owed anything

If this is your first notice and it’s certified, but you weren’t aware of a balance, you could be the victim of identity theft. Or there may be an error, for instance, the IRS may have recalculated something without your input. In this case, you have a short window to challenge or appeal. Get help fast.

You’ve been ignoring previous IRS letters

We get it — IRS mail is stressful. But if you’ve been putting it off, that certified letter likely means the IRS is done waiting. This is your moment to act before they do.

Okay, So What Should You Do Right Now?

Here’s a step-by-step plan you can follow.

Step 1: Pick Up the Letter

If you haven’t yet, go to the post office and sign for the certified mail. Don’t let fear delay you. Knowing what it is puts you back in control.

Step 2: Open It and Read the Top Right Corner

Look for the letter or notice number. It will usually say something like “Notice CP90” or “Letter 1058” in the top corner or near the heading. That number tells you what kind of notice it is and how serious it might be.

Step 3: Check the Deadline

IRS notices are time-sensitive. Some give you 30 days, others 90 days, and some even less. Make note of your deadline to respond, appeal, or resolve the issue.

Step 4: Don’t Panic — But Don’t Ignore It

Whether it’s a misunderstanding, a past-due bill, or a sign of bigger problems, certified IRS letters mean it’s time to act. But you’re not alone.
