Indeed, there are several approaches to tackling this problem of phantom tax. There is tax-loss harvesting, wherein an investor sells investments to reduce amounts that may have attracted phantom tax.

Moreover, realization of trading and other appreciated assets during the low income years will ensure lower taxation.
