Subject: Re: Spousal IRA
Based only on a web search I found this link (not authoritative - see IRS 590-A):

https://www.investopedia.com/r...

For 2022 seems to be:$6,000 a year for individuals under age 50 as of the end of the year and $7,000 for anyone 50 or older
100% of eligible compensation.

I think 2023 is $6500/$7500, age dependent.
