Dear Liz: I read your useful summary of the advantages of Roth IRAs. I recently retired and decided to open a Roth (I know, pretty late) alongside my traditional IRA. I have an investment manager who will hopefully create some gains in that account. One thing that I learned is that I must wait five years before I can begin withdrawing earnings from the Roth tax-free. For this reason, it might be helpful to encourage readers to open a Roth IRA early, with at least a small contribution, to get the clock ticking toward that five-year deadline.

Answer: The five-year rule applies, as you mentioned, only to earnings, since contributions to a Roth IRA can be withdrawn at any time. Once you’re at least age 59½, earnings can be withdrawn without penalty provided the Roth IRA has been open for at least five tax years.

Hopefully you were also informed about the “earned income” rule, which requires you to have earnings — such as wages, salary or self-employment income — in order to contribute to a Roth or traditional IRA. Contributing more than you’re allowed to an IRA or Roth IRA can incur a 6% excise tax per year for each year the excess contributions remain in the account.

If you do have earned income — say you’re working part time in retirement — you can’t contribute more than you earn. If you earn just $5,000 in a year, for example, you can’t contribute the full $7,000 that’s otherwise allowed to people 50 and older. (The contribution limit is $6,000 for younger people.)

If you’ve contributed in error, contact a tax advisor about next steps.
