Form 5498

Unlike most tax forms that must be in the taxpayer's hands before the filing deadline, Form 5498 is issued after the April 15 tax return due date. This is because IRA contributions for the prior tax year can be made as late as the filing deadline, and custodians need to wait until contributions for the previous tax year are finalized before preparing the form. As a result, the IRS extended the 5498 filing deadline to May 31, and the form is primarily for IRS recordkeeping and taxpayer reference rather than a required attachment to the 1040.

Box 1 of Form 5498 captures traditional IRA contributions. Box 2 reports rollover contributions deposited during the year. Box 3 shows the Roth conversion amount, which should match Box 2a of a corresponding 1099-R issued for the same conversion event. Box 10 reflects Roth IRA contributions. Box 11 indicates whether the account is subject to an RMD for the reporting year, and Box 12a states the amount of that RMD — though the actual distribution is reported separately on Form 1099-R. Box 5 shows the fair market value of the account as of December 31, which trustees use as the denominator in the RMD calculation.

Taxpayers do not need to attach Form 5498 to their return, but it is valuable for several purposes. The year-end fair market value helps verify that RMD calculations by the custodian are correct. The contribution amounts allow taxpayers to cross-check their own records and the deductibility determinations made on their return — traditional IRA contributions may or may not be deductible depending on income and workplace plan coverage. Roth IRA contributions are never deductible, but 5498 confirms the contribution was received and preserves a permanent record of basis in the account.

For SEP IRAs and SIMPLE IRAs, contributions by an employer appear on a 5498 as well, providing documentation of the employer deduction taken on Schedule C, Form 1120-S, or another business return. The IRS matching program compares 5498 data against the taxpayer's return to identify cases where RMDs were not taken or where contributions exceeded the annual limits. Excess IRA contributions trigger a 6 percent excise tax under IRC Section 4973, reported on Form 5329, until they are withdrawn or recharacterized.

Holders of inherited IRAs receive a 5498 that reflects contributions of zero and a fair market value as of the prior December 31, along with a Box 11 RMD indicator. Under the SECURE Act and SECURE 2.0, the distribution rules for inherited accounts depend on whether the original owner died before or after their required beginning date and the relationship between the decedent and the beneficiary, making the 5498 an important tracking document across potentially a decade or more of distributions.
