What a Letter 903 is
A Letter 903 is a warning issued by a revenue officer to an employer whose federal employment taxes have not been deposited. The Internal Revenue Manual sets out what it is for:
“Letter 903, You Haven't Deposited Federal Employment Taxes, is used by revenue officers to alert taxpayers to the provisions of IRC 7402(a), which provides the Federal district court with the jurisdiction to pursue civil injunctions under Title 26 and Title 18 of the Internal Revenue Code.” — Internal Revenue Manual 5.7.2, revised 22 May 2025
It is not a bill, it does not assess anything, and it does not itself change what you owe. It is a formal notification, issued by a person rather than a system, that the situation has been recognized as an employment tax problem rather than as a balance.
Two things follow from the fact that a revenue officer issued it. Your case is assigned and not automated — see Letter 725-B, the appointment letter → — and the letter is a record. It exists so that, if the government ever does ask a court for an injunction, it can show the employer was told.
Before anything else: check what else was in the envelope. The manual requires the letter to be handed over with a second document — “Revenue Officers must hand deliver Letter 903 and Notice 931, Deposit Requirements for Employment Taxes, to the taxpayer during a scheduled appointment” — and Notice 931 is nothing but deadlines: the deposit schedules, the four-quarter lookback, the $2,500 rule and the $100,000 next-day rule. It is the document that tells you how to do the thing this letter is asking for. What Notice 931 sets, and the notice that delivers it →
And in one of the situations the manual describes, a second letter travels with this one. IRM 5.7.2.2 contemplates issuing Letter 903 “along with Letter 1058 during initial contact” where the taxpayer is a repeater with no assets. A Letter 1058 is a Final Notice of Intent to Levy and it carries a hard thirty-day clock. If one is in the same envelope, that clock — not this letter — is the thing with a date on it. Letter 1058, the Final Notice →

The sentence people find, and what it actually says
Here is the whole of it, quoted rather than summarized, because the summary is where the damage happens:
“Issuance of Letter 903 is required before a taxpayer can be recommended for civil injunction or criminal prosecution.”
Read it as a sentence about the IRS's obligations, because that is its grammar. It sets a condition on what the IRS may do. It says: no referral without this letter first. It does not say: this letter means a referral is coming.
Why the distinction is more than reassurance. Employment tax cases are common; injunction and prosecution referrals are rare. If the letter were a predictor, the two numbers would be similar and they are not. The letter is the routine step; the referral is the exceptional outcome.
And here is the part we cannot tell you, which is the honest limit of this page. We cannot tell you which of those two you are, because that depends on facts a page does not have — how many quarters are involved, whether the shortfall is continuing right now, whether returns are filed, and what has been said to the officer already. What we can tell you is what moves it in the right direction, and it is in the next section but one.
Your clock
Letter 903 itself carries no deadline, and none is published. IRM 5.7.2 was read in full on 6 September 2026 and gives the taxpayer no period; the letter carries none.
But “this letter has no deadline” is not the same as “you have no deadline,” and the difference is what came with it. Notice 931 sets the date of your next deposit. A Letter 1058, if one is enclosed, starts thirty days. Check the envelope before you accept the reassurance.
What is genuinely time-sensitive here is not a date on a letter — it is the current quarter. The category this letter belongs to is defined by ongoing behavior rather than by a past balance. A separate part of the manual — IRM 5.7.8, “In-Business Repeater or Pyramiding Taxpayers,” subsection 5.7.8.4 dated 9 March 2017 — defines a pyramiding taxpayer as one who is “(1) In business (2) Not current with federal tax deposits (FTDs) (3) Has two or more trust fund modules assigned to Field Collection,” and states the operating instruction plainly: “Pyramiding must be stopped immediately.”
So the clock that matters is the next payroll. A business that becomes current going forward has changed the only fact in that definition it can change today.
What happens if you do nothing
The manual lists three consequences and each is a different kind of thing.
“Failure to comply may result in: Prompt assessment of unpaid liabilities. Assessment of liabilities based upon a return executed under IRC 6020(b). Possible civil or criminal referral.”
| Consequence | What it actually is |
|---|---|
| Prompt assessment | The IRS accelerates assessment of what is owed, rather than waiting for the ordinary cycle. It shortens the runway before collection tools become available. |
| Assessment under IRC 6020(b) | A return prepared by the IRS in place of the one the business did not file, built from what the IRS can see. |
| Civil or criminal referral | The one in the heading. Referral is a recommendation to the Department of Justice; it is not a decision by the IRS and it is not a conviction. |
On the second row, a point that cuts in the taxpayer's favor and is worth knowing. A return the IRS prepares in place of yours does not start the ordinary period the IRS has for assessing tax — only your own filed return does that. A business hoping an unfiled quarter will age out of the system is waiting for a clock that has not started.
And separately from all three, the question that most often actually arrives. Where employment tax is unpaid, the trust fund portion — the money withheld from employees — can be assessed against individuals personally, and that process runs on its own track with its own letter and its own 60 days. It is not on the list above and it is more likely than anything on it. Letter 1153, and when payroll tax reaches a person →
The thing most published guidance about this letter gets wrong
If you have read that a Letter 903 means you will be put on monthly Form 941-M filing and special deposit procedures — that describes a regime the IRS says is no longer required.
“Although IRC 7215 remains in the Internal Revenue Code (IRC), Form 941-M, Monthly Filing and Special Deposit Procedures are no longer required prior to proceeding to the next collection action.” — IRM 5.7.2, revised 22 May 2025
Two things to take from that. The administrative step changed; the criminal provision, IRC 7215, is still on the books and it has not been repealed. And the change is older than it looks: that sentence sits in IRM 5.7.2.1.1, dated 8 February 2021 — the section as a whole was re-transmitted in May 2025, but the 941-M change is five years old. Anything published before 2021 describing monthly filing as the next step is out of date, and that cuts against you rather than for you, because the step that used to sit between this letter and the next collection action is gone.
