RMD Series | How Are RMDs Calculated | Planning Insights
RMDs are calculated by dividing your traditional IRA or retirement plan account balance by a life expectancy factor specified in IRS tables. Your account balance is usually calculated as of December 31 of the year preceding the calendar year for which the distribution is required to be made.
Example(s): You have a traditional IRA. Your 70th birthday is November 1 of year one, and you therefore reach age 70½ in year two. Because you turn 70½ in year two, you must take an RMD for year two from your IRA. This distribution (your first RMD) must be taken no later than April 1 of year three. In calculating this RMD, you must use the total value of your IRA as of December 31 of year one.
Caution: When calculating the RMD amount for your second distribution year, you base the calculation on the IRA or plan balance as of December 31 of the first distribution year (the year you reached age 70½) regardless of whether or not you waited until April 1 of the following year to take your first required distribution.
For most taxpayers, calculating RMDs is straightforward. For each calendar year, simply divide your account balance as of December 31 of the prior Calculator year by your distribution period, determined under the Uniform Lifetime Table using your attained age in that calendar year. This life expectancy table is based on the assumption that you have designated a beneficiary who is exactly 10 years younger than you are. Every IRA owner's and plan participant's calculation is based on the same assumption.
There is one exception to the procedure described above-- the younger spouse rule. If your sole designated beneficiary is your spouse, and he or she is more than 10 years younger than you, the calculation of your RMDs may be based on the longer joint and survivor life expectancy of you and your spouse. (The life expectancy factors can also be found in IRS publication 590.) Consequently, if your spouse is your designated beneficiary and is more than 10 years younger than you, you can take your RMDs over a longer payout period than under the Uniform Lifetime Table. If your beneficiary is not your spouse, or a spouse who is not more than 10 years younger than you, then you must use the shorter payout period specified in the Uniform Lifetime Table.pdf.
Tip: In order for the younger spouse rule to apply, your spouse must be your sole beneficiary for the entire distribution year. Your spouse will be considered your sole beneficiary for the entire year if he or she is your sole beneficiary on January 1 of the year, and you don't change your beneficiary during the year. In other words, even if your spouse dies, or you get divorced after January 1, you can use the younger spouse rule for that distribution year (but not for distribution years that follow). In the case of divorce, however, if you designate a new beneficiary prior to the end of the distribution year, you cannot use the younger spouse rule (since your former spouse will not be considered your sole beneficiary for the entire year).
If you have multiple IRAs, an RMD is calculated separately for each IRA. However, you can withdraw the required amount from any one or more IRAs. Inherited IRAs are not included with your own for this purpose. (Similar rules apply to Section 403(b) accounts.) If you participate in more than one employer retirement plan, your RMD is calculated separately for each plan and must be paid from that plan.IMPORTANT DISCLOSURES Broadridge Investor Communication Solutions, Inc. does not provide investment, tax, or legal advice.
