The Golden Rule of Investing: Hold for 1 Year

The IRS heavily incentivizes long-term investing. If you buy a stock, crypto, or property and sell it within 365 days, your profit is added to your regular paycheck and taxed at your highest ordinary income bracket (up to 37%). But if you wait just one day past the 1-year mark, your tax rate drops dramatically to 0%, 15%, or 20%.

Frequently Asked Questions

Q. What is the difference between short-term and long-term capital gains?

Short-term capital gains apply to assets held for one year or less and are taxed at your ordinary income tax rate (up to 37%). Long-term capital gains apply to assets held for more than one year and benefit from significantly lower tax rates (0%, 15%, or 20%).

Q. How can I avoid paying capital gains tax?

The most common way is to hold your assets for more than a year. If your total income is low enough, your long-term capital gains tax rate could be 0%. For real estate, you can exclude up to $250,000 (Single) or $500,000 (Married) of gain if the property was your primary residence for at least 2 of the last 5 years.

Q. What is tax-loss harvesting?

Tax-loss harvesting is a strategy where you sell losing investments to offset the gains from winning investments. You can use capital losses to offset capital gains, and if your losses exceed your gains, you can use up to $3,000 of those losses to offset your ordinary income each year.
