Understanding Stock Trading Math & Capital Gains
While most modern US retail brokerages (such as Charles Schwab, Fidelity, and Robinhood) offer commission-free trading on US-listed equities, trades are still subject to minor regulatory assessments, including the SEC Section 31 transaction fee and FINRA Trading Activity Fee (TAF) on sell orders.
US Capital Gains Tax Considerations
When realizing a stock profit in a taxable brokerage account, the IRS taxes your gain based on holding duration:
- Short-Term Capital Gains: Assets held for one year or less are taxed at ordinary income tax rates (up to 37%).
- Long-Term Capital Gains: Assets held for more than one year receive preferential tax treatment, with rates of 0%, 15%, or 20% depending on your overall taxable income.
Frequently Asked Questions About Stock Profits
How do I calculate my breakeven share price?
Breakeven price per share = (Total Purchase Cost + Any Selling Fees) ÷ Total Shares. Selling at or above this threshold guarantees that you do not lose money after taking into account all transaction costs.
What is the IRS Wash-Sale Rule?
Under IRS Section 1091, if you sell a stock at a loss and buy the same or a "substantially identical" security within 30 days before or after the sale, you cannot deduct the loss on your current tax return. The disallowed loss is added to the cost basis of the newly purchased shares.
