The back child support amount has grown this year so I'm concerned it will take the entire refund and I don't want to lose my portion that has been withheld from my paychecks through the year.
I file with my name first on the return (not sure if that matters). We live in CA (community property state) and when I tried to answer the questions, I'm not really sure of the questions:
1. There is an understated tax on the return(s) that is due to erroneous items of the person with whom I filed the joint return.
2. I can show that when I signed the return(s) I did not know and had no reason to know the understated tax existed (or the extent to which the understated tax existed).
3. Taking into account all the facts and circumstances, it would be unfair to hold me liable for the understated tax.
4. None of the above
Is back child support considered "understated tax"?
