Since you have not been able to estimate in the past based upon your answer, my suggestion would be to take the average of the investment gains over a period of your choosing and then pay the investment taxes associated with this average over the course of the year plus some percentage extra. You can also look at the monthly dividends, interest, and capital gains each month and then attempt to estimate the investment income each month, though this would be time consuming. Tax efficient investing for your and your advisor may mean different things as well. You may want to have a conversation with the advisor of their efforts to limit the income items associated with your investments.
All the best,
