Are dividends and interest distributions that are reinvested in SJP product taxable in the year that they occur if no funds received into bank account?
Without sight of what you're looking at I can't be sure as I don't deal with DRIP, but I would assume:
price per share = cost of each share acquired with the reinvested dividend - this will be relevant for CGT on eventual sale of the shares
cash equivalent = amount you would have received in cash were you not opted into DRIP, i.e. the amount of dividend that is your income for tax purposes.
