IRS Notice Response Letter Template

River reads the notice, including a photograph of one, works out which type it is, and drafts the response that type requires.

Start here

River reads the notice itself, including a photograph taken on somebody's phone, and identifies it by number and by mailing date before anything else happens. Out of that comes the response the notice type actually calls for, the schedule of documents to enclose, the real deadline with the thing that expires on it, and a log entry with a follow-up date. You never have to work out which letter you are holding, which is the step most people get wrong.

Two notices can say intent to levy and mean entirely different things. A CP504 is a notice of intent to levy under section 6331(d) that reaches your state refund and starts the search for other assets. The LT11 that follows it is the one carrying a hearing, and no levy can be made until 30 days after that notice of your right to a hearing goes out. Miss the second date and the hearing you can take to court goes with it.

Written for the controller, bookkeeper or practice owner who opens the envelope, and for the CFO who was handed it three weeks late. Where a proposed adjustment comes from card settlements counted twice, merchant settlement reconciliation produces the evidence. Bank support is assembled through bank statement conversion, and where the balance is real but the cash is not, the week gets sequenced by the payment prioritization memo before the deadline lands.

One of these deadlines is not like the others

Most response windows on a tax notice are administrative. Answer a matching proposal late and the service still reads it, then issues the statutory notice if you have not resolved it. One window is different in kind. After a notice of deficiency is mailed you have 90 days, or 150 if it is addressed outside the United States, to petition the Tax Court. That is the door to arguing before you pay, and it does not reopen.

The type also decides what you are allowed to argue. A matching proposal is an arithmetic dispute about information returns, so it wants documents and a reconciliation. A collection notice is not about whether the tax is right at all, so arguing the merits there wastes the only window you have. The response River drafts makes the argument the notice is built to receive, in the order the reviewer reads, with each enclosure numbered against the item it supports.

Then the log, which is the part everyone skips and the reason things compound. Four notices on one taxpayer across fourteen months, opened by three different people, look like four small problems. On one page with their periods lined up they are obviously one problem, and usually one the instalment agreement was supposed to have closed. Every entry carries the deadline, what expires on it, what was sent, how it went, and the date to check back.

How it works

  1. Add the notice

    Attach the letter or a photograph of it, including the response form on the back.

  2. Say what you think

    Which parts look wrong to you, and which you already know are correct.

  3. River drafts the response

    Matched to the notice type, with the enclosures listed and the deadline on the front.

  4. Send and diary it

    Post it certified, log what went where, and the follow-up date is already set.

What you get

  • The notice identified from the document itself, including a scan or a phone photograph
  • The real deadline, with the specific right or option that expires when it passes
  • A response written for that notice type rather than a general letter of disagreement
  • Every disputed item answered separately, with the specific enclosure that proves that one line
  • A numbered schedule of documents to attach, and what to do about the ones you lack
  • A log entry per notice with the follow-up date and the escalation it sits inside

Common questions

Can it read a scan or a photo of the notice?

Yes, and that is the normal case, since notices arrive on paper and get photographed on a phone. It reads the notice number, the notice date, the tax period, the amounts and the response-by date straight off the page. A skewed photograph of a folded letter is fine as long as the header block is legible.

Why does the notice type matter so much?

Because it decides both what you may argue and how long you have. A matching proposal wants the original forms re-read and a reconciliation. A collection notice is not about whether the tax is correct at all. Making the right argument to the wrong notice burns the window and produces a reply that reads as non-responsive.

What if I only disagree with part of it?

That is the most common outcome and the response handles it directly. Each item gets answered on its own with its own evidence, the conceded item is conceded plainly, and the recomputation shows what remains. Partial agreement resolves faster than a blanket disagreement, because a reviewer can close the items you are not fighting.

What happens if a deadline has already passed?

River tells you exactly what has gone and what has not, because those are different questions. Most administrative windows still get read after the date. A statutory petition window does not reopen, and knowing that on the day changes what you do next rather than three months later when a levy appears.

Does it handle state notices as well?

Yes. State revenue departments issue their own sequences with their own deadlines and their own appeal routes, and the same reading applies: identify the letter, find the date, make the argument that letter accepts. The log holds federal and state entries side by side, which is where the overlap becomes visible. Most trace back to a balance nobody reconciled, which the year-end package catches earlier.

What if the balance is right and we simply cannot pay?

Then it is a sequencing question rather than a dispute, and the response says so and asks for the arrangement rather than arguing. Withheld employment taxes come out ahead of everything else that week, which is the gate the payment prioritization memo builds the whole run around.

Why keep a log if there is only one notice?

Because there is rarely only one for long, and the second arrives after the first has been filed away. The log is one row per notice with its deadline, what expires, what was sent and when to check. It takes a minute to add and it is the difference between a sequence and a surprise. Across a whole client book it lives inside the client filing calendar.
