To illustrate how this works, consider a 40-year-old married couple filing jointly with a MAGI of $250,000 who want to make a Roth IRA contribution for 2026. They would:
- Subtract $242,000 from their MAGI of $250,000, leaving them with $8,000.
- Divide $8,000 by $10,000. This leaves them with 0.8.
- Multiply 0.8 by the $7,500 contribution limit for adults younger than 50 to get $6,000.
- Finally, they would subtract the $6,000 from the $7,500 limit and end up with a maximum contribution of $1,500 for each spouse for the year.
Keep in mind that all of your IRA contributions count toward the same limit, so if you've also contributed some money to a traditional IRA this year, that could reduce your maximum Roth IRA contribution even further. You must make sure your total annual individual retirement account (IRA) contributions don't exceed $7,000, or $8,000 if you're 50 or older in 2025, and $7,500, or $8,600 if you're 50 or older in 2026..
