Typically, you need to have earned income to contribute to a traditional or Roth Individual Retirement Account (IRA). However, there's an exception for married couples. If one spouse is working and the other isn't, the working spouse can contribute to an IRA on behalf of the nonworking spouse. In 2023, the working spouse can contribute up to $6,500 of their earned income to the spousal IRA. If the nonworking spouse is 50 or older by the end of the year, the contribution limit increases to $7,500. For 2024, the contribution limit rises to $7,000, and the catch-up amount remains $1,000, allowing a total contribution of $8,000 for those 50 or older.
