If I file married filing separate how do I handle stock sales in a joint account ?

When married filing separate how do I handle stock transactions ? I've seen several posts that the sales should be split equally with a note in the taxes who has the registered ss#, but how does that note get added ?  When the stock transactions are imported right from the broker, is there an easy way to split between the 2 returns ?

Is the Brokerage account a joint account?

You will have to enter the information transferred fro the Brokerage firms manually in order to allocate the Gain or Loss equally in your wife's and your returns (50/50). So, unfortunately there is no easy way to do this. 

Additionally, you will not be able to include an explanation when you e-file. If you would like to include an explanation on a certain position you have taken you will have to send a Paper Return accompanied with Form 8275 in order to explain the allocation and avoid any Penalties for underreporting.
