Why am I being taxed on my nondeductible IRA?
Updated: 1/21/2013
Article ID: IAS10177
If you take a distribution from a nondeductible traditional IRA, including converting to a Roth IRA, the portion of the distribution that is deemed earnings will be taxable. The amount is determined by calculating a ratio of basis and account value then applying the ratio to the total distribution to assign the taxable and nontaxable amounts. You cannot choose to withdraw just the nontaxable portion.
