Aaron Tallen, Security Benefit's Vice President, Head of Distribution Ops & 401k Defined Contributions, recently spoke with Kiplinger about the risks of Roth IRAs.
He points out the inability for higher earners to contribute directly to Roth IRAs, and mentions the benefits of conversions. He also mentions tax uncertainty.
"There's the uncertainty of ‘I know where my tax bracket is today, but I have no idea what my tax obligation will be in the future,’" he says. Tax code changes and life circumstances could make it so that the time to optimize tax breaks on retirement savings is during your working years, not retirement, making a Roth IRA a less optimal choice.
