The contribution limits apply to each individual, so married couples may be able to contribute the contribution limit for both spouses. For example, in 2017, a married couple, both of whom are over age 50, may contribute a total of $13,000 ($6,500 each, if there is enough earned income to support this level of contribution). Note: You may continue to fund your IRA for 2016 through April 18, 2017.
So if your income is only $1,500, then $1,500 is the most you can contribute to a Roth. There is an exception that allows Roth accounts for nonworking spouses. If you and your spouse file a joint return but one does not work, the employed spouse can open and contribute to a Roth IRA for the unemployed partner. Generally, the contribution limits for a spousal IRA are the same as for the account held by the working wife or husband.
