Even though tax filing season is well under way, there's still time to make a regular IRA contribution for 2021. You have until your tax return due date (not including extensions) to contribute up to $6,000 for 2021 ($7,000 if you were age 50 or older on or before December 31, 2021). For most taxpayers, the contribution deadline for 2021 is Monday, April 18, 2022.
You can contribute to a traditional IRA, a Roth IRA, or both, as long as your total contributions don't exceed the annual limit (or, if less, 100% of your earned income). You may also be able to contribute to an IRA for your spouse for 2021, even if your spouse didn't have any 2021 income.
