Reporting capital gains on a joint investment account

[lindagalla]

My brother and I have a joint investment account.  I believe the taxing will be going against my SS number.

How do I go about splitting any gains or losses with my brother that is acceptable to the IRS?

Thank you for your quick response.

In Quickbooks, how do I split the gain/loss?
