Do you have a table with life expectancy?

The required minimum distribution for any year is the account balance as of the end of the immediately preceding calendar year divided by a distribution period from the IRS’s “Uniform Lifetime Table.” Use a different table if the sole beneficiary is the owner’s spouse who is ten or more years younger than the owner.  The following can help determine the payout periods and the amount of your required distribution:

• worksheets to calculate the required amount 
• tables to calculate the RMD during the participant or IRA owner’s life:
  • Uniform Lifetime Table – for all unmarried IRA owners calculating their own withdrawals, married owners whose spouses aren’t more than 10 years younger, and married owners whose spouses aren’t the sole beneficiaries of their IRAs
  • Table I (Single Life Expectancy) is used for beneficiaries who are not the spouse of the IRA owner 
  • Table II (Joint Life and Last Survivor Expectancy) is used for owners whose spouses are more than 10 years younger and are the IRA’s sole beneficiaries
