Let's take a look at a question about mutual fund taxation . . .
All of the following are taxable in relation to a mutual fund investment except
A. undistributed capital gains
B. unrealized capital gains
C. reinvested capital gains distributions
D. capital gains distributions from a tax-exempt municipal bond fund
EXPLANATION: a surprising fact about capital gains that a mutual fund portfolio manager realizes is that even if they're not paid out to shareholders, the shareholders are taxed on their fair share of the gains. If the fund does distribute capital gains, the investor is taxed whether she cashes the check or reinvests automatically. And, municipal bonds are subject to capital gains taxes just like other securities. Of course, if a capital gain is "unrealized," there is no capital gain.
