I'm married and live in a community property state. We are filing taxes as married. We also have his mine and ours accounts but technically they are considered "community property".

I have separate property I aquired though an inheritance.
I would like to pay my share of the taxes by borrowing it fom my separate propertyaccount and moving it through the checking account that's in my name. All would be documented.

I have two questions.

Can I pay this back to my separate account or would that be considered commingling? I would pay only the amount I withdrew. No more.

In the future can I pay taxes on separate property with community property funds? Would that change the character of sperate property to community property?
