What a CP215 is
A CP215 is the notice the IRS sends when it has assessed a civil penalty against a business account. Its own text is exactly that brief: "We sent you this notice because we charged you a civil penalty."
The brevity is the problem the page exists to solve, because a civil penalty is a category rather than a charge. The notice names the form the penalty relates to, the tax period, and the Code section it was assessed under — and until you have read those three fields, nothing anyone can tell you about "a CP215" applies to your situation with any confidence.
On the audience question, because the IRS's own website is misleading here. The CP215 page is served under irs.gov/individuals/, which suggests an individual notice. It is not. The Internal Revenue Manual is explicit: "A CP 215, Notice of Penalty Charge, for penalties assessed on MFT 13 with PRN 623 is generated and sent to the taxpayer," against "A CP 15, Notice of Penalty Charge, for penalties assessed on MFT 55." MFT 13 is the business civil penalty account; MFT 55 is the individual one.
If you received this on a personal account and were expecting a business one — or the reverse — check the code. CP15 and CP215 are the same notice for two different kinds of taxpayer, and the difference is not cosmetic: what the penalty can be, and who is ultimately liable for it, both change.
Find the Code section first
Everything on the rest of this page depends on one field on your notice: the Internal Revenue Code section the penalty was assessed under. Find that before anything else. It will be one of a small set — the common ones are 6698 and 6699, 6721 and 6722, 6656, and the foreign-reporting sections including 6038 and 6038A.
Here is what each broad group means, and the differences between them are not small.
| The penalty is under | It relates to | The shape of it |
|---|---|---|
| 6698 / 6699 | A late or incomplete partnership (Form 1065) or S corporation (Form 1120-S) return | Charged per partner or shareholder, per month. A small partnership filing several months late produces a number that surprises people, because it multiplies. |
| 6721 / 6722 | Information returns — W-2s, 1099s — filed late, incorrectly, or not furnished to the recipient | Charged per return, in tiers that increase the longer the delay runs, with annual caps. Volume is what makes these large. |
| 6656 | Failure to deposit payroll taxes on time, or by the required method | Tiered by how late the deposit was. The most common business penalty and the one most likely to recur. |
| 6038 / 6038A / 6677 | Foreign-related information reporting — Forms 5471, 5472, 3520, 3520-A | A different order of magnitude entirely, charged per form per period, and they continue after notice. This group also has its own Appeals treatment. |
⚠️ We are not publishing the dollar amounts for the first three groups, and the reason is worth stating. Those figures are adjusted for inflation annually and are set by revenue procedure, and published content across this industry routinely mixes figures from different years under one heading. A wrong penalty amount on a reference page is worse than no amount, because a business owner uses it to decide whether to bother. The amount on your own notice is the correct one for your year, and it is the only one that matters. If you want the current-year figures, ask — they come from that year's revenue procedure, and that is where they should be read from rather than from memory.
What we can tell you without a figure, and it is the part that changes decisions: whether your penalty multiplies per partner, per return, or per period. That determines whether filing the missing item today materially changes the number — and for the first three groups it very often does.
Your clock
The notice prints a payment date, and the IRS says interest turns on it: "Am I charged interest on the money I owe? Not if you pay the full amount you owe by the notice payment due date. However, interest adds up on the unpaid amount after that date." So the date does something, even though it is not an appeal deadline.
What we are not going to tell you is that nothing expires, because we have not established that and it would be a convenient thing to say. Different penalties under different Code sections carry different review routes, and the international group carries windows of its own. The honest position is that no general appeal deadline is printed on this notice, and that the absence of one on the page is not proof of the absence of one in your case.
The urgency that is clear is economic. Interest accrues from the date above. For penalties that continue to accrue with delay — the foreign information reporting group especially — the underlying number keeps moving too.
One structural point that catches people, and it is genuinely important. Assessable penalties like these bypass deficiency procedures. There is no 30-day letter, no Notice of Deficiency, and no route to the Tax Court before paying. The IRS assesses first. Relief runs through an abatement request, or through the IRS Independent Office of Appeals after assessment.
So "I'll wait and challenge it when they send the formal letter" is a plan built on a letter that is not coming. This is the formal letter.
⚠️ One exception we are flagging rather than detailing. The international information-return penalties carry their own post-assessment Appeals process with its own timing. We have not verified those windows against a primary source and are not going to guess at them. If your notice cites 6038, 6038A, 6677 or a Form 5471/5472/3520, treat the timing as something to establish rather than assume, and establish it before doing anything else.

What triggered it
Something was filed late, filed wrong, not filed, or not deposited on time — and the assessment is usually automatic. For most of these penalties no person reviewed your circumstances. A due date passed, a system compared what it expected against what it had, and the penalty posted.
That is worth knowing because it shapes the relief argument. An automatic assessment has not considered your reasons, which means your reasons have not been rejected. They have not been heard. That is a meaningfully better starting position than most people assume from the flatness of the letter.
What happens if you do nothing
The penalty stands, interest accrues, and the balance enters the ordinary business collection sequence — the CP161 reminder line, and from there the same lien and levy machinery that applies to any business tax debt.
Two things specific to penalties are worth adding.
Relief does not expire, but it gets harder to fix. Reasonable cause arguments rest on contemporaneous facts — what happened, when, and what records exist. Those get worse with time, not better.
And penalties of this kind recur. A failure-to-deposit penalty usually reflects a process rather than an incident, and a business that gets one and changes nothing tends to get another. The second one is a materially worse conversation than the first, because the pattern is now part of the record.
