A missing 1099-R starts with the payer: the plan administrator, IRA custodian or insurer that made the distribution. The client asks for a copy, and the year-end account statement shows the gross payout and federal tax withheld. The distribution code is the hard part, and if the form never comes, Form 4852 can stand in for it.
Who issues a missing 1099-R and when is it due?
Form 1099-R is issued by whoever paid the retirement money out: a plan administrator for a 401(k) or pension, a trustee or custodian for an IRA, or an insurance company for an annuity. Recipient copies are due January 31 of the following year, or the next business day when that date falls on a weekend.
The Instructions for Forms 1099-R and 5498 (2026) say "the payer, trustee, or plan administrator must file Form 1099-R," generally for distributions of $10 or more, and cover distributions from retirement plans, IRAs, annuities and similar arrangements. The General Instructions for Certain Information Returns (2025) (reviewed 30 April 2026) list January 31 as the recipient date for Form 1099-R. Because January 31, 2026 was a Saturday, statements for tax year 2025 were due by February 2, 2026.
Finding the right payer
The first question for the client is which account paid out. A client may think of "my 401(k)" when the payer on the form is a recordkeeper with a different name, or think of an annuity as insurance rather than retirement. Last year's return helps: a 1099-R from the same payer last year often means another one this year. A client who moved an old plan into an IRA during the year gets the 1099-R from the old plan, not from the new IRA; the receiving account reports the deposit on Form 5498 instead.
When a 1099-R is truly late
IRS Topic 154, what to do if a Form W-2 or Form 1099-R is missing or incorrect (reviewed 24 September 2026), says to contact the payer if the form is not available by February 2, 2026, the tax year 2025 date. After that, the IRS call at the end of February works the same way for a 1099-R as for a W-2; the post on a missing W-2 explains when the IRS steps in and what the call needs. Furnishing dates for the other common forms are listed in the post on when 1099s arrive, by form.
Many custodians post the 1099-R in the client's online account before the paper copy arrives. A request that names the account and the custodian's website gets a faster answer than "send your retirement forms." The same approach works for other forms that live in an online account, such as a student's tuition statement; the post on a missing 1098-T and education credits covers that case.
Can a 1099-R be rebuilt from the year-end account statement?
A 1099-R can be partly rebuilt from the year-end account statement. The statement's transaction history usually shows each distribution's gross amount and any federal tax withheld, which are the figures for Box 1 and Box 4. What the statement rarely shows is the distribution code, and that code decides how the payout is taxed.
The 1099-R instructions define Box 1 as "the total amount of the distribution before income tax or other deductions were withheld," including direct rollovers and Roth conversions. Box 4 is federal income tax withheld. On a statement, the gross amount may appear as a single withdrawal line or as a withdrawal plus a separate withholding line. Add them if the statement shows only the net deposit to the client's bank.
Box 2a, the taxable amount, is harder to rebuild. For IRA payouts, the instructions say the payer typically checks Box 2b, "Taxable amount not determined," leaving the taxable figure to the taxpayer. A statement does not settle that question either.
A fictional IRA statement mapped to 1099-R boxes
This example is fictional. The client is Marcus Lindqvist, age 62, with a traditional IRA at an example custodian, account ending XXXX-4821. Amounts are example values for tax year 2026.
| Statement line (example) | Amount | 1099-R box it would fill |
|---|---|---|
| Distribution, 14 May 2026, gross | $12,000 | Box 1, gross distribution: $12,000 |
| Federal tax withheld on the distribution | $1,200 | Box 4, federal income tax withheld: $1,200 |
| Net paid to checking account | $10,800 | No box; this is Box 1 minus Box 4 |
| Account type: traditional IRA | IRA/SEP/SIMPLE checkbox, Box 7b | |
| Owner's age at distribution: 62 | Box 7a distribution code: 7 |
The withholding is 10 percent of the gross. That matches the IRS page on rollovers of retirement plan and IRA distributions (reviewed 31 May 2026), which says IRA distributions default to 10 percent withholding unless the owner elects otherwise. The code is 7 because the instructions define code 7 as a normal distribution for a participant at least 59½, and nothing on the statement points to a rollover, a death benefit or a disability. If the statement had shown a deposit to another IRA within days, the code alone would not tell the whole story; the last section of this post covers that case.
Why the 1099-R distribution code matters more than the amount
The 1099-R distribution code in Box 7 (Box 7a on the 2026 form) tells the IRS what kind of payout the amount was: early, normal, a death benefit, a disability payment or a direct rollover. Two payouts of the same amount can be taxed very differently by code, so a guessed code is riskier than a slightly wrong amount.
Table 1 in the 1099-R instructions defines the codes. A few of the most common:
- Code 1, "Early distribution, no known exception," for a participant under 59½.
- Code 2, "Early distribution, exception applies," used only when the payer knows an exception applies.
- Code 3, "Disability."
- Code 4, "Death," for payments to a beneficiary regardless of age.
- Code 7, "Normal distribution," for a participant at least 59½.
- Code G, "Direct rollover and direct payment," from a qualified plan, 403(b) or governmental 457(b) to another plan or IRA.
The cost of a wrong code shows up in two places. IRS Topic 558, additional tax on early distributions from retirement plans (reviewed 24 September 2026), says the law imposes a 10% additional tax on certain early distributions, generally those taken before age 59½. It also says Form 5329 is needed when the tax applies and code 1 is not shown, or when an exception applies but the code box does not identify it. So a code that differs from the payer's code can trigger a form the return would not otherwise need, or a mismatch with what the payer filed.
The second cost is the rollover. A code G payout moved straight to another account. A code 1 or 7 payout went to the client. If the client then deposited it into an IRA, the return has to show that, and the form alone will not.
When the form is missing, the code is the one figure worth waiting for. The IRS wage and income transcript lists 1099-R data the payer filed; the post on the IRS wage and income transcript for missing forms covers what it shows and when it fills in.
Using Form 4852 when a 1099-R never arrives
Form 4852 is the IRS substitute form a taxpayer files when a payer does not provide a 1099-R or provides a wrong one. Line 8 is its 1099-R section, with the gross distribution, taxable amount, withholding and distribution codes. The form tells the taxpayer to try the payer first, and then the IRS, before filing it.
The IRS page About Form 4852 (reviewed 19 August 2026) says it "serves as a substitute for Form W-2, Form W-2c, and Form 1099-R (original or corrected)" and is used when the payer "does not give them a Form W-2 or Form 1099-R" or issues an incorrect one. Topic 154 puts it last in the order: the payer first, then the IRS call, and Form 4852 only if the form still does not come.
Line 8, the 1099-R section
Form 4852 (Rev. September 2020) breaks line 8 into ten items: 8a gross distribution, 8b taxable amount, 8c a box for "taxable amount not determined," 8d a box for a total distribution, 8e capital gain, 8f federal income tax withheld, 8g and 8h state and local tax withheld, 8i employee contributions and 8j distribution codes. The line 8 instructions say that without complete information from a 1099-R, the taxpayer should "use a distribution statement from your plan trustee," which is the year-end statement mapping shown earlier. For line 8j, the instructions point to the 1099-R code list and say to write "IRA," "SEP" or "SIMPLE" in the margin when the payout came from one of those accounts.
Two more lines finish the form. Line 9 asks how the amounts were determined, for example from a statement. Line 10 asks the taxpayer to explain the attempts made to get the form from the payer.
Topic 154 and the form itself state the consequence of a late arrival. If the real form arrives after filing and differs from the estimate, the taxpayer must file Form 1040-X. The distribution code has to be chosen from the definitions, not guessed.
Line 7, the wage section of the same form, is built from pay stubs. The post on how Form 4852 is built from pay stubs walks through that, so this section covers only what is different for a retirement payout: the codes, and the "taxable amount not determined" box.
Keep the record of each contact attempt in the client file: the date, the person or department, and what the payer said. If the real 1099-R later arrives with a different code, that record explains how the original figure was chosen. A corrected W-2 raises the same question for wages, covered in the post on a corrected W-2 after filing.
1099-R edge case: an indirect rollover the client forgot to mention
An indirect rollover is a distribution paid to the client that the client then deposits into another plan or IRA within 60 days. The 1099-R shows it as an ordinary payout, not code G, so a client who forgets to mention the redeposit can look as though they cashed out the whole account.
The IRS rollovers page states the rule: "You have 60 days from the date you receive an IRA or retirement plan distribution to roll it over to another plan or IRA." The IRS may waive the deadline in some situations beyond the taxpayer's control. Two details from the same page explain why the numbers look odd. A plan distribution paid to the participant is subject to mandatory 20% withholding, even if the participant intends to roll it over. And only one IRA-to-IRA rollover is allowed in any 12-month period across all of a person's IRAs, though trustee-to-trustee transfers do not count.
The records that show the money went back in
The receiving account reports the deposit on Form 5498. The 1099-R instructions say Box 2 of Form 5498 covers "a 60-day rollover" between IRAs and a "direct or indirect (within 60 days) rollover" from a plan. Form 5498 runs on a later calendar than the 1099-R, so it may not be in the client's hands at filing time. The receiving custodian's deposit confirmation or monthly statement, showing the date and amount, fills the gap until it does.
How the gap shows up
Watch for a 1099-R with a large Box 1 and code 1 or 7 from a client who says they "moved" a 401(k). Ask for the receiving account's statement for the 60 days after the distribution date. If 20% was withheld, the client may have deposited only the net amount, or made up the withheld part from other money; the statement shows which.
A firm sees the pattern faster when last year's 1099-R payers and this year's are listed side by side. Schema CPA uses last year's return as each client's checklist and flags a form that came in last year and has not come in this year, which puts a new or missing 1099-R in front of the preparer early; the workflow steps are on the homepage.
