Why you might want one

  • Expect to be in a lower tax bracket in retirement.
  • Want to lower your current taxes.
  • Don’t want to pay taxes now with the Roth: It can take several years of investment earnings to recoup the amount lost to pay taxes on Roth contributions when deducted from your paycheck.
  • Are close to retirement, expect to start taking distributions and don’t have several years to wait for compounding of after-tax Roth contribution earnings to make up for the tax liability paid when Roth contributions are deducted from your paycheck.
  • Don’t think you will meet the criteria for Roth distributions to be tax-free: For example: if the account won’t be open for at least 5 years and you won’t be at least age 59½ (or disabled or deceased) when a distribution is taken, then the earnings will not be tax-free.
  • Expect to be in a higher tax bracket in retirement.
  • Want qualified tax-free distributions in retirement.
  • Want option to postpone required minimum distributions at age 70½ (requires roll over to a Roth IRA).
  • Cannot have a Roth IRA due to IRS income restrictions.
  • Want to pass on assets tax-free to heirs.
  • Want to make after-tax Roth contribution in excess of Roth IRA limits.
  • Have a long retirement horizon that will allow time to accumulate significant tax-free assets in the form of compounding on earnings which can be withdrawn tax-free.
  • Want tax diversification of having both after-tax and tax-deferred assets as a hedge against potential tax increases.
  • Want to contribute the maximum allowable: A qualified Roth distribution may provide more income in retirement than an equivalent distribution from a tax-deferred 403(b) or 457(b) since Roth earnings are tax-free instead of just tax-deferred.
