I live in California, and understand that I can lower my state tax burden by moving from CDs to Treasuries. Is this only true for individual treasuries owned by me, or is it also true for bond funds that hold Treasuries? Does it matter if the fund holds Treasuries exclusively, or other bonds as well? Not sure it matters, but I'm already a Vanguard customer and am considering VFISX. Thanks for any help in understanding this.

2. It does matter if the fund holds only Treasuries, or whether it gets income from other assets as well.
3.For 2017 info re Vanguard funds, including VFISX, go to https://personal.vanguard.com/pdf/USGO_022018.pdf (Most, but not all, of the 2017 income from VFISX, is exempt from state and local income taxes.)




At first blush, the chart seems ugly. Just remember the NAV is impacted by the distributions, so it's not as bad as it looks. The ER is pretty high, and that was always a concern to me. As I said, I bailed when the bailing was good, a couple of years back.
