Dear Liz: I have a 401(k) that has a required annual distribution because I am over 71 1/2 years old. Can I use this distribution as qualified income to invest in a Roth IRA? I have no W-2 earnings, although I do have other income sources that are reported on 1099 forms.

Answer: To contribute to a Roth or other individual retirement account, you must have taxable compensation, which the IRS defines as wages, salaries, commissions, tips, bonuses or net income from self-employment. The IRS also includes taxable alimony and separate maintenance payments as compensation for IRA purposes.

So if the money reported on one of those 1099 forms is from self-employment income, then you can contribute to a Roth IRA. If the form is reporting interest and dividends or other income that doesn’t meet the IRS definition of taxable compensation, then you’re out of luck.
If you don’t have income that meets the IRS definition of taxable compensation, but your spouse does, you may still qualify for IRA contributions, provided you file a joint return that meets the required income thresholds.
