I paid an average of $0.31 per kWh last month with SCE (which is on the low side, because a lot of that is charging my car, which I have setup to only charge during off-peak). I see under $0.06 per kWh of Non Bypassable Charges. The word "tax" does not appear on the bill, except in a notice about raising rates which mentions a loss (with the word "after-tax" appended to the amount of the loss) incurred by SCE.
