The second half of the document
K-1 with a statement attached: the part that is not on the form
A K-1 with a statement is one document in two halves, and the second half is where the numbers live for anything that did not fit. The practical question is not what the statement says — it is whether you actually have it.
Attachments arrive separately more often than anyone expects. The partnership emails the K-1 and the statement as two PDFs, or the portal download produces a packet where the statement sits after three other partners' pages, or the client forwards the first email and not the second. The face of the K-1 looks identical in all three cases.
Five kinds
What an attachment can be, and what is lost without it
| Form of the reference | What it carries | What you record | What goes wrong without it |
|---|---|---|---|
| A code with STMT in the amount space | The amount for that code, sometimes split into lines | The letter is recorded with no figure | The code looks like it has a zero value. On the return it becomes a deduction that was never taken. |
| Asterisk beside a code | An explanation or expansion of an item that does have a figure | The amount and the asterisk, as a note | The number is entered correctly and the reason it might be limited is lost. |
| Activity statement (at-risk or passive) | Each activity with its own items | The checkbox state, plus the statement as a separate file | The whole loss is entered as one activity and every later carryforward is wrong. |
| Property distribution detail | Description, fair market value and basis of property received | The box 19 code and a pointer to the description | Basis is reduced by the wrong number, usually the fair market value. |
| Section 199A detail | QBI, W-2 wages, UBIA and related items | The code Z row and the statement's page range | The 199A deduction is computed from a guess or skipped entirely. |
The count, which takes ninety seconds and settles the question
Work through the K-1 from box 11 to the end of part three and put a mark on every reference you find: a STMT in an amount space, an asterisk beside a code, a checked activity box. That is your expected number of statement sections.
Now count the sections in the attachment. Each normally begins with a header naming the partner and the year. If the two numbers do not match, stop. Either the file is incomplete or the packet contains pages belonging to another partner, and in both cases the figures you already have are not yet usable on their own.
Then check the identity line on each statement section: partner name, identifying number, tax year. Statements are produced in batches from a template, and a batch that was assembled in the wrong order produces sections that are internally consistent and belong to somebody else.
Recording it so the next person does not repeat the work
For each reference, three fields: the box or code it came from, the page of the statement it points at, and what the statement was. That third field is the one people skip, and it is the only one that tells a reviewer whether an item was read or merely found.
Where a statement arrives as a separate file, record the file name and the page range rather than merging everything into one folder of loose pages. A statement that cannot be shown to belong to its K-1 is a statement that will be relitigated the first time someone asks.
Three cases worth handling differently
- A statement with more detail than the K-1 references. Common for charitable and 199A statements, which sometimes include the partnership-level totals so the investor can see their share. The extra lines are context, not additional amounts, and adding them into a total is how a statement gets double-counted.
- Two statements for one code. A code can be expanded twice — once in the partnership's own statement and once in the fund administrator's summary. They should agree with the K-1, and if they do not, the later document is the one to ask about in writing.
- A statement in a different language or currency. The figures are still the figures, but the currency needs recording next to the amount. A converted figure written into the amount column destroys the trail back to the printed one.
The box-level guides carry the destination detail for the two boxes that generate most statements: box 13 and box 20. The rule underneath all of it is the one in the reading step: characters go across as printed, and anything that is not printed on the page is a reference, never a value.
Plain answers
Questions about attachments
What does STMT mean on a K-1?
That the amount for that code or box is on an attached statement rather than on the face of the form. It is a pointer, not a value. Entering zero is the single most consequential mistake that can be made with a K-1, because the return will look complete and will be missing a deduction or an income item.
Is the statement part of the K-1?
For your purposes, yes. The K-1 is not complete without it, in the same way a form with a missing page is not a form. Keep them in one file with the page ranges recorded, so the next person can tell at a glance whether the attachment was ever received.
How do I know whether a statement is missing?
Count the references on the face of the K-1 — every STMT and every asterisk — and compare that with the statement sections in the file. Then check whether the last page of the K-1 continues into a numbered statement page. A K-1 whose page numbering stops before a statement section is a truncated file, not a simple K-1.
Does an attachment ever change the number?
It can. Where the statement breaks an item into components with different treatments, the total is the same but the destination is not. That is why the letter and the statement have to be read together rather than the letter alone being totalled.
Does K1 FastTax read the statement?
No. It reads the face of the K-1, keeps STMT as the word STMT rather than a number, and records the page. The statement itself is a document you read, route and keep, and the checks here are about making sure it is there.
STMT stays STMT
K1 FastTax reads the face of a K-1 PDF and writes STMT where the form says STMT, with the page of the reference, so a missing attachment is visible before the return is keyed.
