Anything you earn will affect your community income and taxes. California is a community property state. If you file a joint tax return, all income and deductions are added together on the same return. If you file separately, then it is spit 50/50 on each of your respective tax returns.
Also, when you file as Married Filing Separately, if one spouse
itemizes on Schedule A, the other must also itemize on Schedule A.
Is it better for a
married couple to file jointly or separately?
