For which type of income distribution would the investment firm issue a T3 form to...

A T3 slip reports trust income allocations, including distributions from mutual fund trusts held in non-registered accounts. If a mutual fund trust distributes dividend income, interest income, capital gains, or return of capital to a unitholder in a taxable account, the investor receives tax reporting that identifies the character of the distribution. Mutual funds held inside an RRSP do not generate current taxable reporting to the investor because taxation is deferred until withdrawal. Capital gains from directly traded stocks in a non-registered account are normally tracked by the investor using trade confirmations and tax records, not reported as a mutual fund trust distribution. Therefore, a dividend distribution from mutual funds held in a non-registered account is the best answer.
