Interest paid on money borrowed to buy property held for investment is investment interest. Such interest is deductible but generally limited to the taxpayer’s net investment income for the year.2 Generally, interest incurred to produce tax-exempt income is not deductible.
Property held for investment includes property that produces interest, dividends, annuities, or royalties not derived in the ordinary course of a trade or business. It also includes property that produces gain or loss (not derived in the ordinary course of a trade or business) from the sale or trade of property producing these types of income or held for investment (other than an interest in a passive activity). Investment property also includes an interest in a trade or business activity in which the taxpayer did not materially participate (other than a passive activity).3
