What a Letter 725-B is
A Letter 725-B is how a revenue officer makes first contact. The IRS's description:
“We've scheduled a meeting to discuss unfiled tax returns and any unpaid balance you may owe. We've assigned a date, time, and location for the meeting. We may schedule the meeting to take place at an IRS office, your business or over the phone. We've included the contact information for the revenue officer assigned to your account.”
Two facts about what has happened, and they point in opposite directions.
The reassuring one: this is an appointment. It carries a date because appointments do. It is not a legal instrument, nothing is being demanded on it, and nothing about your rights changes on the date printed.
The one that deserves respect: your account is no longer with the automated system. Letters until now were generated by a machine that follows a sequence. A revenue officer is a person, assigned to your case, who sets their own deadlines, exercises judgment, and has enforcement tools available directly. The letter's own subject line tells you what put you there: the IRS describes it as scheduling a meeting “to discuss unfiled tax returns and any unpaid balance you may owe.”

Why this letter exists at all
Until July 2023, this contact would have been someone at your door. The IRS ended that:
The IRS “announced a major policy change that will end most unannounced visits to taxpayers by agency revenue officers,” replacing them with “an appointment letter, known as a 725-B.” — IR-2023-133, 24 July 2023
The exceptions are narrow and worth naming, because they are the situations where someone may still arrive without warning: “service of summonses and subpoenas; and also sensitive enforcement activities involving seizure of assets, especially those at risk of being placed beyond the reach of the government.” The IRS put a number on how rare that now is — those “typically number less than a few hundred each year, a small fraction compared to the tens of thousands of unannounced visits that typically occurred annually under the old policy.”
This matters for a practical reason beyond history. A great deal of published advice about revenue officers — including advice written by tax professionals — still describes what to do when one turns up unannounced. That advice is describing a practice that ended three years ago, and it is not the situation you are in.
Your clock
The date on the letter is an appointment, and appointments move. There is no statutory period running and nothing expires on that date.
That is the honest answer and it is the one people most need, but it should not be read as “the date does not matter.” Missing it without calling is what turns an appointment into a problem, because the officer's next step is not another appointment.
What the IRS says happens if there is no response:
“We may take actions including: Collect balances owed. Substitute return preparation. Reject or terminate an installment agreement. Issue a levy. Seizure of assets. File a notice of federal tax lien.”
Read that list carefully, because its structure is the useful part. Every item on it requires steps of its own — a levy requires a Final Notice of Intent to Levy and the hearing rights that come with it; a seizure requires approvals and, for some property, a court. The list describes the officer's toolkit, not a schedule. What a Final Notice of Intent to Levy actually starts →
Calling to reschedule is not avoidance and it is not a mark against you. It is the first thing the IRS's own page tells you to do.
The two rights that decide how this goes
These are statutory, they are short, and almost nobody arrives at that meeting knowing them.
First: you can stop the interview to get a representative, at any point.
“If the taxpayer clearly states to an officer or employee of the Internal Revenue Service at any time during any interview (other than an interview initiated by an administrative summons issued under subchapter A of chapter 78) that the taxpayer wishes to consult with an attorney, certified public accountant, enrolled agent, enrolled actuary, or any other person permitted to represent the taxpayer before the Internal Revenue Service, such officer or employee shall suspend such interview regardless of whether the taxpayer may have answered one or more questions.” — Internal Revenue Code section 7521(b)(2)
The last twelve words are the ones that matter, and they are the ones usually cut. Having already answered questions does not spend the right. The IRS's own manual instructs the officer to allow “a minimum of 10 business days for the consultation with an authorized representative” and to hand over a Form 9297, Summary of Taxpayer Contact, recording what is wanted and by when.
Second: if you are represented, the IRS cannot make you attend.
“An officer or employee of the Internal Revenue Service may not require a taxpayer to accompany the representative in the absence of an administrative summons issued to the taxpayer under subchapter A of chapter 78.” — Internal Revenue Code section 7521(c)
Read what that rule is about: attendance. Your representative can attend and you need not. It applies to “any interview described in subsection (a)” — an in-person interview — so by its terms it does not reach a telephone appointment.
And there is a second statute, about contact rather than attendance, which is the one most often misdescribed:
“the Secretary may not communicate with a taxpayer in connection with the collection of any unpaid tax— ... (2) if the Secretary knows the taxpayer is represented by any person authorized to practice before the Internal Revenue Service with respect to such unpaid tax and has knowledge of, or can readily ascertain, such person's name and address, unless such person fails to respond within a reasonable period of time to a communication from the Secretary or unless such person consents to direct communication with the taxpayer.” — Internal Revenue Code section 6304(a)
The IRS's manual restates it plainly: “If a valid Form 2848 is on file and covers all open periods contact must be made with the representative” (IRM 5.1.10.7.2, 24 April 2025). It governs collection contact rather than examination contact, it has three stated exceptions, and it is enforceable by a civil action under section 7433.
Where these rights stop, and the limits are statutory rather than administrative. The summons carve-out is written into section 7521(b)(2) itself, in the parenthetical above — an interview initiated by an administrative summons is not suspended. Section 7521(d) takes criminal investigations out of the section entirely. A summons is a different document and it does not look like this one.

What triggered it
Three things put a case in front of a revenue officer, and they are not equally serious.
| What the letter names | What is being asked for |
|---|---|
| Unfiled returns | The returns, with a date for each |
| An unpaid balance | A financial picture and a proposal for the balance |
| Both, where the balance is employment tax | The two above, plus the business becoming current going forward |
The third row behaves differently from the other two and it is worth establishing which you are in — the officer will tell you if you ask. Where the balance is unpaid employment tax, a case carries a question that has nothing to do with the business at all: whether the trust fund portion should be assessed against a person.
