What is the maximum amount that I can contribute to my spouses IRA as a spousal IRA contribution?
Spousal IRA contributions are generally limited to the same dollar amount as regular IRA contributions (e.g., $5,000 for 2009, $6,000 if qualifying for catch-up contribution). However, when using the spousal contribution rules, the maximum aggregate amount that may be contributed between two spouses is equal to the eligible compensation (generally earned income) of the compensated spouse, or if both have some compensation, the combined amount.
