If a US citizen, not true. We've left the state, and we didn't need any withholding on the proceeds.
Now, we did live in the house long enough for its value to quadruple, so we'll be owing capital gains taxes to both Uncle Sam and California. A bit of a first world problem, but worth the cost to have escaped from California last month.
So, where’d you move to...we’re thinking of exiting Oregon...getting just like CA...only worse weather.
