Don't forget to file the 3840 with CA for every year in the future!
"All taxpayers, regardless of residence status or commercial domicile, who
exchange real property located in California for like-kind property located
outside of California, must file form FTB 3840 with their California tax return.
Taxpayers who exchange multiple assets involving both real and personal
property located in California for like-kind property located outside of California
are also subject to this requirement. Taxpayers who exchange only personal
property assets are not required to file form FTB 3840.
If the taxpayer is not otherwise required to file a California tax return, the
taxpayer must complete the entire form FTB 3840, including the signature
area at the bottom of Side 1, and file form FTB 3840 at the address shown in
General Information D, Where to File.
For purposes of the California filing requirement, the term “taxpayer” or
“taxpayers” includes all individuals, estates, trusts, general partnerships,
limited partnerships, limited liability partnerships, limited liability companies,
and corporations."
