Net Investment Income represents the excess of investment income over investment expenses. Individuals are allowed to deduct for tax purposes the Investment Interest Expense to the extent of their net investment income.
Net Investment Income (NII) is the amount by which investment income exceeds investment expenses. Investment income typically includes interest, dividends, capital gains, rental income, and royalties. Investment expenses, on the other hand, include interest expenses on funds borrowed to invest, advisory and brokerage fees, and other expenses directly related to generating investment income.
In tax contexts, individuals can deduct Investment Interest Expense to the extent of their net investment income, thereby reducing their taxable income.
Investment Interest Expense refers to the interest paid on money borrowed to purchase taxable investments. According to tax laws in many jurisdictions, taxpayers can deduct this expense up to the extent of their net investment income.
