What is a brokerage account?

A brokerage account — sometimes called a taxable brokerage account or taxable investment account — is an account at a licensed securities firm that gives you access to financial markets. The SEC registers and oversees broker-dealers in the U.S. You deposit cash, and the broker executes buy and sell orders on your behalf. Unlike retirement accounts, brokerage accounts have no annual contribution limit and no restrictions on withdrawals.

How taxes work on brokerage gains

In a taxable brokerage account, you owe taxes when you sell a security for a gain. The rate depends on how long you held it. Short-term capital gains (held less than 1 year) are taxed at your ordinary income tax rate. Long-term capital gains (held 1 year or more) are taxed at preferential rates: 0%, 15%, or 20% depending on your income. Dividends may be qualified (lower rate) or ordinary (higher rate). The IRS Topic No. 409 on Capital Gains and Losses covers the rules. Your brokerage will send a Form 1099-B each year summarizing your reportable transactions.

SIPC protection: what is — and isn't — covered

Brokerage accounts at member firms are covered by the Securities Investor Protection Corporation (SIPC) up to $500,000 ($250,000 cash sublimit) per customer. SIPC protects against the financial failure of a broker-dealer — it does not protect against investment losses from market declines. SIPC coverage is not the same as FDIC insurance. If your brokerage fails, SIPC works to return your securities and cash held there; it cannot restore losses from bad investments.

When a taxable brokerage account makes sense

Most financial planners recommend maxing tax-advantaged retirement accounts (401(k) match → IRA → remainder of 401(k)) before funding a taxable brokerage account for retirement. However, brokerage accounts are the right tool when you: (1) have already maxed retirement accounts; (2) need investment access before age 59½ without penalties; (3) want no contribution limits; or (4) are saving for goals shorter than retirement. Self-employed investors who've maxed their Solo 401(k) or SEP-IRA often use brokerage accounts as the next layer.
