Calculating your RMD

ARTICLE TAKEAWAYS

  • How to calculate your IRA RMD amount
  • Using the IRS tables to determine your current RMD factor
  • How your RMD is reported on your tax forms 

Required minimum distributions (RMDs) are calculated by dividing your account’s prior year-end balance by the applicable IRS life expectancy factor. If you have multiple IRAs, or other tax-deferred retirement accounts subject to an RMD, you must calculate the RMD amount for each account individually.

Note: RMDs are not required for Roth IRAs.

Information needed to calculate your RMD:

  1. The prior year-end account balance, which you can find on your year-end statement or by logging in to your account
  2. Your IRS life expectancy factor — The IRS provides tables to determine the factor to use each year, based on your age and the beneficiary on the account:
    1. Uniform Lifetime Table — Use this table to calculate lifetime RMDs from IRAs and retirement plan accounts for unmarried account owners, married owners whose spouses aren't more than 10 years younger and married owners whose spouses are not the sole beneficiary
    2. Joint Life and Last Survivor Expectancy Table — Use this table to calculate RMDs from IRAs and retirement plan accounts when the sole beneficiary is the account owner’s spouse who is more than 10 years younger

Note: Additional factors are available on the IRS website. Consult with your tax advisor for details on your situation.

Formula for calculating your RMD:

To calculate your account’s current-year RMD:

Example: Brian is an IRA owner who turned 76 on March 31. His daughter, Susan, is the beneficiary on his account. On December 31 of last year, the ending balance in the IRA was $262,000. To calculate his RMD for this year, he divides $262,000 by his life expectancy factor of 23.7 years. His distribution amount is $11,054.85.

Prior year-end account balance / IRS factor = Your RMD for the year

$262,000 / 23.7 = $11,054.85

Calculating your RMD if you have more than one IRA:

Your RMD must be calculated separately for each IRA you own, each year. Once you have determined each account’s RMD amount, you can withdraw the total amount from one or more of your IRAs.

Note:

  • If you have a 403(b), you must calculate the RMD for each 403(b) account separately, but you can take the total amount from one or more of your 403(b)s
  • RMDs from 401(k), 457, money purchase plan and profit-sharing plan accounts must be taken separately from each plan


How your RMD will appear on your tax forms

Distributions, including any federal and/or state tax withholding, taken during the calendar year are reported on Form 1099-R. If you are age 59½ or older, the amount is coded as a normal distribution.

RMDs are generally fully taxable. It is the IRA owner and their tax advisor’s responsibility to determine the tax liability.

Inherited IRAs

There are several factors that impact how to calculate the RMD amount for an inherited IRA, including:

  1. The beneficiary’s relationship to the IRA owner
  2. The beneficiary’s age
  3. Whether the IRA owner had started taking RMDs


Contact a tax advisor or financial professional for assistance in completing the calculation and refer to IRS Publication 590-B, Distributions from Individual Retirement Arrangements (IRAs).
