Hi! My sister and I have a joint savings account and my SSN is the one on the 1099 INT form. I haven't submitted my tax return yet but I currently am allocating 50% of the interest income to me and checking the "I am a nominee" box. I'm advising her to then claim 50% of that interest income as well. However, since the 1099 INT form is in my name, how would the IRS know that the interest income she is claiming is for this joint account? I just want to make sure the system sees that we have claimed 100% of the interest income between our two accounts. Would they be able to track it using her SSN too since I'd imagine given she's a joint owner, the account is also associated with her SSN even if form 1099 INT doesn't include it?
Thank you so much!
