What are the limits on my wife contributing to an IRA if she doesnt have a 401K at work?

I do have a 401k and contribute to it but not to the max and it is a joint IRA. If she is eligible, what would the limit be?

So she does make wages. go to IRS.gov and get the info. I think it's about $4,000. It used to be $2,000. sometimes there are other variables that affect what can be contributed, like age to retirement. so you got to check it out because I don't know.

the limit is $4,000 and if she is over 50 years old, she can add an extra $1,000 for a total of $5,000
