My question involves a marriage in the state of: California
Income that will be reported on next year's tax filings also can complicate community property issues, so a join tax return or two married filing separately might need to be considered. An example would be stock in a company being sold which has a tax liability.
"Separate property can be transmuted into community property not only by agreement but by actions too. Seemingly innocuous acts, like one person making a mortgage payment on their spouse's separate residence, can have an impact."
Does filing cause an issue?
