It will depend on whether you have other income or not (eg retired or not).

If you don’t have other income the first 45k if single or $90k if married of long term cap gains will be taxed at 0%.

In that case your effective tax rate in CA is around 12% if you’re single or only 2.7% if married, which is going to be a lot lower than any income that is taxed as ordinary income.

You are tossing together several unrelated things here, not sure why.

-federal zero L/T cap gains rate if taxable in come is low enough -- this has zero relevance to CA tax

-different thresholds depending on filing single or married-joint (previous example was for single filer)

-CA "effective" tax rate - while there is no single definition of this, it is clear that no one with an AGI of $100K has anywhere near a CA effective rate of 12%.

I meant overall tax rate for someone based in California...

You are making some case that because California doesn't treat long term capital gains differently that it doesn't make much difference if you were taxed from realizing LTCG or ordinary income in California and your overall tax burden (federal + state) would be about the same.

I'm just pointing out if you're retired, you would naturally have a much lower tax burden if you realized LTCG vs $100k in ordinary income because the federal tax rate for LTCG would be so low for someone with no other income.
