When you sell an investment for more than you paid, the profit is a capital gain, and how long you held the investment before selling can change the tax you owe on it dramatically. The distinction between short-term and long-term gains is one of the most consequential and controllable in investing.
The dividing line is generally one year. Gains on investments held for a year or less are short-term and are typically taxed at your ordinary income tax rates, the same as your salary. Gains on investments held longer than a year are long-term and are generally taxed at lower, preferential capital-gains rates. Same gain, different tax, decided by the calendar.
The difference can be substantial, especially for higher earners, because ordinary income rates can be considerably higher than long-term capital-gains rates. That means selling a winning investment just before the one-year mark can cost meaningfully more in tax than waiting a little longer, a reason many long-term investors are mindful of holding periods before selling appreciated assets.
The tax tail should not wag the investment dog, selling decisions should be driven by your plan, not solely by taxes, but the holding period is a real factor worth weighing, and coordinating with tax-loss harvesting and your overall bracket. Because rates and thresholds change and depend on your situation, the specifics belong with your tax advisor. Awareness of the one-year line is the takeaway.
A year can change what the gain costs you.
