The difference between ordinary income and unearned income
The big difference between ordinary income and other income, known as unearned income, is how it's taxed. Unearned income comes in the form of long-term capital gains and qualified dividends.
Long-term investors can collect this type of income over time. Since the government wants to encourage long-term investments in businesses and other assets, it provides preferential tax rates on unearned income. Unearned income can be taxed as low as 0%. However, most investors will pay 15% on their long-term capital gains and qualified dividends.
Some high-income households will pay a 20% tax on some or all of their unearned income, and some must pay an additional 3.8% on their net investment income if their adjusted gross income exceeds a certain threshold. Federal taxes on a dollar of unearned income will usually be less than or equal to those on a dollar of ordinary income.
