Many new investors celebrate when they sell a stock for a massive profit, only to be hit with a brutal surprise come tax season. The US tax code heavily differentiates between how you make your money and how long you hold your assets.

To estimate your overall tax burden this year, start by using our comprehensive Income Tax Calculator.

Ordinary Income vs. Capital Gains

Your salary from a W-2 job is considered ordinary income and is taxed at the highest brackets. However, investment profits are taxed differently.

If you buy a stock and sell it for a profit in less than a year, it is a Short-Term Capital Gain, which is taxed exactly like ordinary income. If you hold that asset for more than a year, it becomes a Long-Term Capital Gain, which unlocks heavily discounted tax brackets (0%, 15%, or 20%).

Before you ever click "Sell," run the numbers through our Capital Gains Calculator to see if waiting a few weeks could save you thousands.

Tax-Loss Harvesting

What happens if you have a stock that lost money? You can sell it to realize the loss, and then use that loss to cancel out your gains.

For example, if you made $10,000 on Tesla stock, but lost $4,000 on another stock, you can sell the losing stock. Now you only owe taxes on $6,000 of net profit. This strategy, called tax-loss harvesting, is used by billionaires to drastically reduce their Income Tax burden.

The Power of Tax-Advantaged Accounts

To avoid annual taxes on dividend payouts and stock growth, maximize your use of 401(k)s and Roth IRAs. Money growing inside a Roth IRA is completely tax-free forever. If you want to see how powerful this is, project a tax-free growth curve using our Compound Interest Calculator or plan your retirement with our Retirement Calculator.

Final Takeaway

Never let taxes be an afterthought. By holding assets for over a year and utilizing tax-loss harvesting, you can legally keep more of your money. Check your potential liability today with our Capital Gains Calculator.
