A client will be receiving a 1099-INT in 2025.  However, the interest will be split 50/50 with her sister.

I understand my client has to send the IRS a 1099-INT with her sister's information and her share of the interest.

My question is as follows:  does my client only claim half of the 1099 interest on her tax return?  That seems to lead to a letter from the IRS regarding the other half?

I seem to remember there was once a way to claim all the interest, and then deduct "nominee interest" on Schedule B.

Comments please!

Thank you!
