Step up of basis

[11Buster]

CA husband and wife own their principal residence as community property.  Husband dies.  Does wife get step up only to FMV at DoD on his 50% ownership in property or 100% of the property FMW?  What about if held as joint tenants?

[TaxGuyBill · Accepted solution]

California is a Community Property State, so it is a full step up.

If not community property and joint tenancy then the step up is 50% (on deceased's portion only).
