Quick answer: LT11 and Letter 1058 are two different formats of the same underlying document — the IRS’s Final Notice of Intent to Levy and Notice of Your Right to a Hearing, issued under Internal Revenue Code Section 6330. Legally, they carry identical weight: the same 30-day deadline, the same right to a Collection Due Process (CDP) hearing, and the same authority to levy your wages, bank accounts, or other property once that window closes. The real difference is who sent it. LT11 comes from the IRS’s Automated Collection System (ACS) — a computer-generated notice tied to a phone-queue account. Letter 1058 comes from a local Revenue Officer who has been personally assigned to your case and is working it in the field. That distinction matters more than the paperwork suggests, and it’s worth understanding before you decide how to respond.

The short comparison

	LT11	Letter 1058
Issued by	IRS Automated Collection System (ACS)	A local Revenue Officer (field collection)
Full title	Notice of Intent to Levy and Notice of Your Right to a Hearing	Final Notice — Notice of Intent to Levy and Notice of Your Right to a Hearing
Who’s handling your account?	A rotating pool of ACS phone representatives	One named IRS employee with a direct line
Typical case type	Lower-complexity accounts still in the automated phone queue	Cases judged to need hands-on collection work
Legal authority under IRC § 6330	Yes	Yes
Deadline to request a CDP hearing	30 days from the notice date	30 days from the notice date
Form to respond	Form 12153	Form 12153
What happens if ignored	IRS may levy wages, bank accounts, and other assets	IRS may levy wages, bank accounts, and other assets — often faster, since a Revenue Officer already has the file open

If you’ve received either one, the paperwork itself isn’t the thing to focus on. The clock is.

LT11 is generated by the IRS’s Automated Collection System, the division that handles collection on accounts that haven’t yet been assigned to an individual employee. If your unpaid balance has been sitting in ACS’s queue — meaning your prior contact with the IRS, if any, has been through the general 800-number or a series of computer-generated notices — LT11 is the version you’ll get.

It’s typically a few pages: a summary of what you owe by tax year, an explanation of your right to a CDP hearing, and instructions for requesting one. Because it’s system-generated, there’s no name attached to it beyond a generic IRS phone number and address. Calling that number connects you to whichever ACS representative picks up, not someone who already knows your file.

Letter 1058 means your account has moved past ACS and into the hands of a Revenue Officer — an IRS employee assigned to your specific case, usually because the balance, the type of tax, or the case’s history made it a candidate for direct fieldwork rather than automated handling. Revenue Officers work a defined territory and a defined caseload, and they have the authority to investigate your finances, file liens, and issue levies without routing the case back through a call center.

Letter 1058 often reads as more detailed than LT11 because the Revenue Officer already has case-specific information. It typically includes that officer’s name, badge number, and direct phone or fax line — a real, findable person rather than a general queue.

There are also variants worth knowing about: Letter 1058-A is sometimes used for related notices to a business entity’s responsible parties, and some Revenue Officers use Letter 1058-B or 1058-D for related account types. Whichever version lands in your mailbox, the underlying legal mechanism is the same one described below.

Legally, yes. Both satisfy the IRS’s obligation under IRC § 6330 to give you formal notice and a hearing right before it can levy your property. Both must be delivered by certified or registered mail (or given in person, or left at your home or usual place of business) to your last known address. Both start the same 30-day countdown to request a Collection Due Process hearing using Form 12153. Neither one is a “worse” notice in terms of what it legally authorizes — a levy is a levy, regardless of which letterhead announced it.

What differs is the person behind it, and that has practical consequences. An LT11 case is still, in a sense, anonymous — you’re one account among thousands moving through an automated system, and depending on staffing and case volume, there can be a gap between the notice date and any actual enforcement action.

A Letter 1058 case has already been pulled out of that queue and handed to someone whose job is specifically to resolve it, which often means the follow-through is faster and more direct. A Revenue Officer can request a full financial statement (Form 433-A or 433-B), verify your assets independently, and move to levy without waiting on a separate department to act.

Neither notice guarantees a delay and neither guarantees speed — case volume, staffing, and the size of your balance all play a role. But if you’re trying to gauge how quickly you need to act, “a specific person with my name on their desk” is a reasonable signal to treat Letter 1058 with slightly more urgency in practice, even though the legal deadline is identical on paper.

Neither notice arrives out of nowhere. They’re the last step in a sequence that usually looks like this:

1. CP14 — the first bill. The IRS states what you owe and asks you to pay it. The tone is administrative, not adversarial.
2. CP501 — a reminder notice sent when CP14 goes unanswered.
3. CP503 — a second, more pointed demand notice. This is generally the point where the IRS starts treating the account as unresolved rather than simply unpaid.
4. CP504 — a notice that the IRS intends to levy your state tax refund and may file a federal tax lien. This one surprises a lot of people: CP504 sounds like the final warning, but on its own it does not carry Collection Due Process rights and doesn’t authorize a levy on your wages or bank accounts. That authority comes from the next notice in line.
5. LT11 or Letter 1058 — the actual Final Notice of Intent to Levy. This is the document that starts your 30-day CDP window and, once that window closes, gives the IRS the legal authority to levy wages, bank accounts, Social Security benefits, and other property.

Some accounts move through every step above in order. Others — particularly business accounts with payroll tax issues, or cases involving larger balances — get assigned to a Revenue Officer earlier, which is why some taxpayers receive Letter 1058 without ever seeing an LT11 first.

The 30 days run from the date printed on the notice, not the date you happened to open the envelope. If you want to preserve your right to a Collection Due Process hearing — and, with it, the ability to eventually petition the U.S. Tax Court if you disagree with the outcome — Form 12153 needs to be postmarked or submitted within that window, mailed to the address listed on your specific notice.

Requesting a CDP hearing does more than get you a conversation with the IRS Independent Office of Appeals. It also generally pauses levy action while the hearing is pending, and it gives you a formal setting to raise collection alternatives: an installment agreement, an Offer in Compromise, currently-not-collectible status, or a dispute over whether you actually owe the amount assessed (if you haven’t already had a chance to contest the underlying liability).

You still have options, just fewer of them. You can request an Equivalent Hearing within one year of the notice date, using the same Form 12153. It gets you a similar conversation with Appeals about collection alternatives, but it comes with two real costs: it typically doesn’t suspend levy action the way a timely CDP request does, and if you disagree with the outcome, you lose the right to take the matter to U.S. Tax Court — your only recourse at that point is district court, a materially higher bar.

In practice, this is the most consequential difference in the entire process, and it has nothing to do with whether you received an LT11 or a Letter 1058. It comes down entirely to whether you acted inside the 30-day window.

If the 30 days pass with no response, no payment, and no arrangement in place, the IRS has the legal authority to levy. In practice, that can mean:

• A bank levy, freezing and eventually seizing funds in your account (after a mandatory 21-day hold on funds present at the time of the levy, giving you a short window to resolve it before the funds are actually turned over).
• A wage garnishment, where a portion of every paycheck is sent directly to the IRS until the balance is paid or another arrangement is reached.
• A levy on Social Security benefits, state tax refunds, or other federal payments.
• Filing of a Notice of Federal Tax Lien, which becomes public record and can affect your ability to sell property or obtain credit — separate from a levy, but often occurring around the same time.

There’s also a longer-range consequence worth knowing about: under the FAST Act, the IRS certifies “seriously delinquent tax debt” to the State Department, which can result in denial or revocation of a passport. For 2026, that threshold is $66,000 in combined unpaid tax, penalties, and interest, adjusted annually for inflation.

The IRS sends a separate notice, CP508C, when it certifies a debt this way — it isn’t automatic just because you received an LT11 or Letter 1058, but an unresolved balance that reaches that level over time can trigger it.

The steps are the same regardless of which version you received:

1. Confirm the notice is legitimate and check the numbers

Verify the tax years and amounts against your own records. The IRS sends these notices by mail, not by text or email — treat any electronic version claiming to be one as a phishing attempt.

2. Identify who’s actually working your account

If it’s an LT11, the notice will list the general ACS phone number. If it’s a Letter 1058, call the Revenue Officer directly using the number printed on the letter — that person owns your case and can discuss options no one else at the IRS can authorize on your behalf.

3. Decide whether you’re disputing the debt or the collection action

If you believe the amount is wrong, or you never had a prior chance to contest it, that’s a substantive issue to raise at a CDP hearing. If the amount is correct and the question is how to pay it, that’s a conversation about collection alternatives.

4. File Form 12153 within 30 days if you want a CDP hearing

Even if you plan to resolve the balance through a payment arrangement anyway, requesting the hearing preserves your appeal rights and generally pauses levy action while it’s pending.

5. Get the paperwork moving on a resolution in parallel

An installment agreement application, financial disclosure for an Offer in Compromise, or documentation supporting a currently-not-collectible request — rather than waiting for the hearing date to start assembling it.

6. Bring in representation if the balance is significant or the facts are complicated

A Revenue Officer in particular is trained to move a case toward resolution on the IRS’s terms; having someone negotiate on your behalf shifts that balance of power in your favor.

For the legal deadline, no — 30 days is 30 days either way. For how you should actually spend that time, yes. An LT11 usually means you still have some room to work the phones, get documentation together, and reach a resolution before the case escalates to fieldwork.

A Letter 1058 means that escalation has already happened: a Revenue Officer has reviewed the file, decided it warrants direct attention, and has the standing authority to act without further internal approval. Treat Letter 1058 as a signal to move faster, not because the law demands it, but because the person on the other end of that letter is already positioned to enforce it.

1. Is Letter 1058 worse than an LT11 notice?

Not in terms of legal authority — both permit the same levy actions after 30 days. Letter 1058 does typically mean a Revenue Officer has already reviewed your case and is prepared to act on it directly, which is a reasonable signal to respond sooner rather than later.

2. Do I have less time to respond to Letter 1058 than to LT11?

No. Both give you 30 days from the notice date to request a Collection Due Process hearing using Form 12153.

3. Can I negotiate directly with the person who sent Letter 1058?

Yes, and you generally should. The Revenue Officer’s name and direct phone number are on the letter, and that person has the authority to discuss payment arrangements, request financial documentation, or hold enforcement while you work toward a resolution.

4. What if I already have a payment plan and still got one of these notices?

Contact the number on the notice immediately. This can happen when a new tax year’s balance falls outside an existing agreement, or when a processing delay caused the notice to go out before your arrangement was fully recorded. Don’t assume it will resolve itself.

5. Does receiving LT11 or Letter 1058 mean the IRS will levy immediately?

No. It means the IRS can levy after the 30-day window closes if the balance remains unresolved and you haven’t requested a CDP hearing. Filing Form 12153 within that window generally pauses levy action while your case is under Appeals review.

6. Can these notices lead to a passport being revoked?

Not directly. Passport certification is a separate process tied to whether your total tax debt — including penalties and interest — has crossed the “seriously delinquent” threshold, set at $66,000 for 2026. The IRS notifies you of that separately, through Notice CP508C.

7. What form do I need to file to protect my hearing rights?

Form 12153, Request for a Collection Due Process or Equivalent Hearing, mailed to the address shown on your specific LT11 or Letter 1058 within 30 days of the notice date.

The label on the envelope tells you which part of the IRS is handling your file. It doesn’t tell you what your options are, and it doesn’t buy you extra time. What matters is what you do inside the 30 days you’ve got — filing Form 12153 if you want to preserve your appeal rights, getting real numbers in front of the right person, and putting a resolution in motion before the decision gets made for you.

 Leading Tax Group works with taxpayers at exactly this stage, reviewing the notice, confirming what’s actually owed, and dealing directly with the ACS representative or Revenue Officer assigned to the account. If you’ve received an LT11 or Letter 1058 and aren’t sure which of the six steps above applies to your situation, that’s the conversation worth having before the deadline passes rather than after.
