Frequently Asked Questions

How are stock profits taxed?

In the U.S., stocks held less than a year are taxed as short-term capital gains (ordinary income rates). Stocks held over a year qualify for long-term capital gains rates of 0%, 15%, or 20% depending on your income.

Should I include brokerage fees in profit calculations?

Yes, always include fees. While many brokers now offer commission-free trades, some still charge per trade. Even small fees add up and reduce your effective return, especially on smaller trades.

What is the difference between realized and unrealized gains?

A realized gain occurs when you actually sell the stock and lock in the profit. An unrealized gain (paper profit) is the increase in value of shares you still hold and have not sold.
