These are errors and rejects every filer can get when sending information returns to IRIS, whether through the free IRIS Taxpayer Portal or through filing software. IRIS reports each one on the acknowledgment by rule number.
Form 5498 business rules
Besides the rules on this page, IRIS checks the rules every form shares, such as SHAREDIRFORM014 (payee name and TIN); those are on the cross-form error code pages. The IRIS Taxpayer Portal also takes Form 5498 as a CSV upload, using the IRS template for the form.
In the tax year 2026 rule set: 3 report error and reject over the threshold, 1 report error. A reject stops the submission; a report error is accepted with errors and counts as filed; past an unpublished threshold, report errors reject the submission. The descriptions are our own summaries; your acknowledgment gives the rule number.
| Rule | Severity | What it checks |
|---|---|---|
| F5498001 | Report error, reject over threshold | If a rollover contribution or fair market value is reported, one account type must be checked: IRA, SEP, SIMPLE or Roth IRA. |
| F5498002 | Report error, reject over threshold | Life insurance cost included in IRA contributions cannot be more than the IRA contributions. |
| F5498003 | Report error, reject over threshold | If a repayment of a distribution is reported, the repayment code is required. |
| F5498017 | Report error | For a postponed or late contribution, the reason must fit the code: executive order numbers 13239, 12744 or 13119 with code EO, or public law 115-97 or 106-21 with code PL. |
Elements of Form5498Detail
Each Form 5498 return is one Form5498Detail record in a submission of group 1. The table lists its 31 elements in schema order for tax year 2026: whether each is required, and the format IRIS accepts. Element names are the ones the IRS uses in its IRIS ATS examples and Publication 5718; the IRS revises the schema each year. A FIRE filer converting a Pub 1220 file finds the field-by-field mapping in the Pub 1220 to IRIS crosswalk.
