First, you have two goals that may be a challenge and difficult to achieve. You indicate that you want to increase the value of your retirement accounts and minimize federal and state taxes. With regard to increasing the value of your accounts, that depends on your asset allocation and if you elect to take distributions from those accounts. The Traditional IRA (TIRA) will require you to take distributions at age 72 which is about 8 years from now. However, you need to supplement your SS benefits currently. You did not indicate how much you need which is critical in determining which account or combination of accounts should be used to minimize your federal and state taxes. Assuming you have no other taxable income, it makes financial sense to withdraw money from your TIRA to equal the Standard Deduction (SD) which for 2021 is $12,550/$25,100 single/married. Upon attainment of age 65, the SD increases by $1,700 for single and $1,350 each if married. Remember, the SD will vary from year to year. Next, withdraw money from your TIRA to equal the maximums for the 10% federal tax bracket which is $9,950/$19,900 single/married. Remember, when working, your contributions to your TIRA were made, at probably, higher tax brackets (i.e. 15%,25% or greater). So, whenever, you can withdraw from your TIRA at tax rates less than 15%, you have a huge win. At this point, as a single you have $22,500 ($12,550 plus $9,950) of TIRA distributions and owe federal taxes of $995.00 (10% X $9,950). If married filing jointly, you have $45,000 ($25,100 plus $19,900) of TIRA distributions and owe federal taxes of $1,990. You are correct to say that distributions from your Roth IRA are not taxable. So, on the surface, they may appear to be the choice that minimizes your federal taxes. However, you need to address the fact that your Roth contributions were made with after tax dollars, probably when you were working. Those Roth contributions, in effect, were taxed at 15%, 25%, or greater (starting 2018: 12%, 22% or greater) unless your income from working put you in the 10% tax bracket. You can work the math if you need more money to supplement your SS benefits. The 12% federal bracket for single covers taxable income from $9,951 to $40,525. For married filing jointly, the 12% federal tax bracket covers taxable income from $19,901 to $81,050. Without knowing the amount of money you need to supplement your SS benefits, I will venture a guess and say that withdrawing from your TIRA is a financial advantage up to the taxable income maximums of the 12% tax brackets ($40,525/$81,050 single/married). Remember, taxable income starts after your SD of $12,550/$25,100 single/married (under age 65). Using your Roth would not be a financial advantage inasmuch as you paid greater taxes on those contributions. Save the Roth for your surviving spouse since your spouse will be taxed as a single or your heirs if you are not married.
