I seem to recall that California, at one time, required people who earned their retirement in California to pay California State Income Tax, even when they lived in another State. Eventually, the issue was taken up by the Supremes and it was declared unconstitutional.

Yes. Kalif demanded that the Nevada AG help collect these “source taxes.” The Nevada AG told Kalif to go pound sand.

You are correct.

DW and I are benefitting from that decision right now. Of course we moved to Oregon, which has even higher taxes than CA. But, DW's situation is even more delicious. She worked for the state, so not only does she not have to pay taxes in CA, but CA collects taxes from Californians in order to pay her pension.
