what is the limit for additional traditional IRA contributions for 2025 for myself who contributed 9k to a work 401k plan and my wife who hasn't contributed for 2025?

[ThomasM125]

Since you have a retirement plan at work, if you file as married-joint, your contribution is limited if you earn between $126,000 and $146,000 and eliminated in 2025 once your income is over $146,000. Otherwise you can contribute up to $7,000 for you and your spouse individually if under age 50, and $8,000 if over that. You can learn more in IRS Pub 590-A.

ThomasM25's reply confuses the limit on deductibility of a traditional IRA contribution with eligibility to contribute to a traditional IRA.  Neither your contribution nor your wife's contribution amount is limited by participating in a workplace retirement plan.  What may be limited is the amount of that contribution that is deductible.
