Final answer:
Unitholders in a mutual fund trust commonly receive the 1099-DIV form to report dividends and capital gains distributions. Other forms such as the 1099-INT for interest income or the 1099-B for broker transactions may also be provided to report different types of investment income accurately when filing taxes.
Step-by-step explanation:
Unitholders in a mutual fund trust will receive specific tax slips that inform them of their investment income for the tax year. The most common tax slip for reporting investment income from a mutual fund in many countries is the 1099-DIV form. This form reports the dividends and capital gains distributions that the investor has received from the fund. Additionally, for certain types of income or distributions, a unitholder may also receive other forms such as the 1099-INT for interest income, or the 1099-B for proceeds from broker and barter exchange transactions. It's important to use the information on these tax slips when filing your taxes to report investment income accurately.
