How do IRA owners report Roth IRA Contributions?
Because Roth IRA contributions are made with after‑tax dollars and are not deductible, the IRS does not require taxpayers to list regular Roth IRA contributions on their individual income tax return. The owner must, however, keep their own records of Roth IRA contributions to properly determine whether the five‑year rule has been satisfied when distributions are taken.
It is important to note that while the IRA owner will not report Roth IRA contributions on their tax return, the Roth IRA trustee/custodian must report all Roth IRA contributions made (as well as the fair market value) to the IRS on Form 5498, IRA Contribution Information.
