In addition, estates and trusts with investment gains over $12,950 must pay taxes on investment.

Examples of Investment Income

2. Dividends from stocks and mutual funds are also subject to the tax on investment income.

3. Capital gains from selling stocks, mutual funds, or other investments are subject to the tax on income.

How do you avoid taxes?

There are a few ways to avoid taxes on income. One way is to invest in tax-exempt investments such as municipal bonds or charitable trusts. These offer a tax-free return on investment. Another way is to invest in assets not subject to capital gains tax, such as real estate or gold. You can offset your income with investment losses.
