Thank you for your question concerning Required Minimum Distributions.
According to the Internal Revenue Service (link: https://www.irs.gov/retirement-plans/retirement-plan-and-ira-required-minimum-distributions-faqs), "You cannot keep retirement funds in your account indefinitely. You generally have to start taking withdrawals from your IRA, SIMPLE IRA, SEP IRA, or retirement plan account when you reach age 72 (73 if you reach age 72 after Dec. 31, 2022)."
The only account not subject to required minimum distributions are Roth IRAs. However, Roth IRAs that are part of a 401(k) or 403(b) retirement plan are subject to the RMD rules for 2022 and 2023. "However, for 2024 and later years, RMDs are no longer required from designated Roth accounts. 2023 RMDs due by April 1, 2024, are still required."
"Your required minimum distribution is the minimum amount you must withdraw from your account each year.
- You can withdraw more than the minimum required amount.
- Your withdrawals will be included in your taxable income except for any part that was taxed before (your basis) or that can be received tax-free (such as qualified distributions from designated Roth accounts)."
Since your non-deductible contributions are included in a "traditional" IRA, those contributions will be subject to the minimum distribution rules. However, since you have already paid taxes on these contributions, you will not incur additional taxes when the non-deductible contributions are distributed. This prevents paying taxes twice on such contributions.
