Quick answer
Form 5498 reports IRA contributions, rollovers, Roth conversions, and December 31 account value. Your custodian files it with the IRS by May 31, not you. You do not need it to file your return, but box 5 sets the pro-rata denominator that determines whether a backdoor Roth is actually tax free.
Form 5498 is the form nobody asks for and everybody misreads. It arrives in May, weeks after most people have already filed, with a heading that says "IRA Contribution Information" and fifteen boxes of data you were never told to expect. The instinctive reaction is to assume you made a mistake and need to amend.
You almost certainly do not. Form 5498 is filed by your IRA custodian, not by you. Your copy is a receipt. But one box on it, box 5, silently determines whether the backdoor Roth conversion you did this year is tax free or a taxable event, and that is worth understanding before you file it away.
What Form 5498 Actually Is
An information return the custodian files with the IRS. You are copied, not obligated.
Every institution that holds an IRA has to tell the IRS what went into it. Form 5498 is that report. The custodian files a copy with the IRS and sends you an identical copy. Nothing about the form asks you to do anything, and there is no line on Form 1040 where a 5498 gets attached or entered.
Form 5498 reports money going IN
- Traditional and Roth IRA contributions
- Rollovers from a 401(k) or another IRA
- Roth conversions
- SEP and SIMPLE employer contributions

Form 1099-R reports money going OUT

- Required minimum distributions taken
- Early withdrawal penalty coding
Every Box, Line by Line
Fifteen boxes. Four of them matter to most people.
Most taxpayers only ever see entries in boxes 1, 2, 3, 5, 7, and 10. The rest exist for self-directed accounts, disaster relief provisions, and edge cases. Here is the full map.
| Box | Reports | What it means |
|---|---|---|
| 1 | IRA contributions | Traditional IRA contributions made for the tax year, including those made between January 1 and the filing deadline of the following year. |
| 2 | Rollover contributions | Amounts rolled into the IRA from another retirement plan. A rollover reported here is not a taxable contribution. |
| 3 | Roth conversion amount | Amounts converted from a traditional, SEP, or SIMPLE IRA to a Roth IRA. This is the number that should tie to your Form 8606. |
| 4 | Recharacterized contributions | Contributions moved from one IRA type to another before the deadline. |
| 5 | Fair market value of account | The December 31 account value. This drives required minimum distribution math and the pro-rata rule denominator. |
| 6 | Life insurance cost in an endowment contract | Rare. Applies only to certain endowment contracts held inside an IRA. |
| 7 | Account type checkboxes | Marks the account as IRA, SEP, SIMPLE, or Roth IRA. |
| 8 | SEP contributions | Employer SEP contributions received during the calendar year, reported on a cash basis rather than by plan year. |
| 9 | SIMPLE contributions | Employer and salary deferral contributions to a SIMPLE IRA received during the calendar year. |
| 10 | Roth IRA contributions | Direct Roth IRA contributions. This is the running record of your Roth basis, which matters if you ever withdraw early. |
| 11 | RMD checkbox | Checked if you must take a required minimum distribution for the following year. |
| 12a and 12b | RMD date and amount | The deadline and the calculated required minimum distribution for the following year. |
| 13a, 13b, 13c | Postponed or late rollover contributions | Contributions made under a disaster provision, a military exception, or a self-certified late rollover, plus the year and reason code. |
| 14a and 14b | Repayments | Repayments of qualified reservist or qualified disaster distributions, with a code identifying the type. |
| 15a and 15b | Hard to value assets | Fair market value and a code for assets without a readily available market price, such as real estate or a private note held in a self directed IRA. |
Taxstra Tip
Box 10 is the only running record of your direct Roth IRA contributions, and it is the number that lets you withdraw contributions penalty free before age 59 and a half. Custodians change hands, statements get purged, and this history is painful to reconstruct twenty years later. Save every 5498 in one folder permanently.Why It Arrives in May
The due date is built around the prior year contribution window.
You can make a traditional or Roth IRA contribution for a tax year right up to that year's filing deadline in April. The custodian cannot finalize what you contributed for the year until that window closes. So the IRS set the Form 5498 filing deadline at May 31, after the contribution window shuts.
The timeline that causes the panic
January
You get W-2s and 1099s. You start thinking about filing.
April
You file. You may also make a prior year IRA contribution on the way, which is exactly why the 5498 cannot exist yet.
May
Form 5498 arrives reporting everything, including the contribution you made in April. Nothing is wrong. This is the design.
One case where the May arrival does matter
If you contributed to a traditional IRA intending to deduct it, and the 5498 shows the amount credited to the wrong tax year, the IRS matching system will flag your deduction. Fix it with the custodian first. An amended return built on an uncorrected 5498 will not clear the notice.The Box 5 Trap for Backdoor Roth
The one number on this form that can cost a high earner real money.
High earners phased out of direct Roth contributions typically use the backdoor Roth: contribute to a traditional IRA on a nondeductible basis, then convert it to Roth. The pitch is that the conversion is tax free because there was no deduction to recapture.
That is only true if you have no other pre-tax IRA money. The pro-rata rule treats every traditional, SEP, and SIMPLE IRA you own as one combined account, and box 5 across all of those accounts is the denominator.
Worked example
You contribute $7,000 nondeductible to a new traditional IRA and convert it immediately. You also have an old rollover IRA from a former employer with a box 5 value of $193,000.
Illustrative arithmetic only. Your figures depend on your own account balances and basis.
Nearly the entire conversion is taxable, and most people who do this do not find out until a preparer reconciles the 5498 against the pro-rata rule on Form 8606. The usual fix, rolling the pre-tax balance into a current employer 401(k) before December 31, has to happen before the year ends, which is why this is a planning conversation and not a filing-season one.
When a Mismatch Matters
Three checks worth two minutes when the form arrives.
Box 1 against your claimed IRA deduction
If you deducted a traditional IRA contribution, box 1 should match it. A difference usually means the custodian coded the contribution to the wrong year.
Box 3 against Form 8606
Your reported conversion amount should tie to box 3. This is the pairing the IRS matching system checks most often on backdoor Roth returns.
Box 5 against every other IRA you own
Add box 5 across all traditional, SEP, and SIMPLE IRAs. If the total is anything other than zero and you did a backdoor Roth, your conversion was partly taxable.
If you are also holding a health savings account, expect a separate Form 5498-SA on the same schedule, and if you are self-employed, compare what an IRA actually allows against solo 401(k) contribution limits before assuming the IRA is your best vehicle. Beneficiaries reading a decedent's 5498 should start with the inherited IRA rules, where box 11 and box 12 drive the distribution schedule.
