Are mutual fund expense ratio fees count as investment expenses and tax deductib

[tax44]

Are they deductible in state of CA?

No.

Investment expenses are no longer deductible, with the new 2018 tax law.  Even in the "old days", they were only a misc. itemized deduction subject to the 2% of AGI threshold.

Expense ratio fees were not deductible then or now, because they are built in to the net asset price and not directly charged to the shareholders.
