Enter the sale and where the new property is. See what California withholds at closing, the form you file every year, and the state tax still waiting on your gain.
Common mistake: "I moved to Texas and the new property is in Texas, so California is done with me." No. California tracks the gain you built here. Form 3840 is due every year, even if you live out of state, and even after later exchanges out-of-state to out-of-state. Skip it and FTB can assess the deferred gain plus penalties and interest.
Ken will reply with the forms and a few CPAs who handle out-of-state 1031s. No spam.
