What is portfolio income? If you didn't earn it in your business or as wages, it's generally portfolio income. That includes interest, dividends, annuities and royalties from property held for investment. It also includes gains from the sale of properties that produce portfolio income or that you hold for investment. However, if you receive interest in the course of your business, that interest income is not portfolio income.
