What Is an IRA

Retirement investing benefits from time, and taxes on dividends, interest, and realized gains can slow the growth of a regular taxable account. An IRA addresses this by sheltering investments from annual taxation while the money stays in the account. In exchange for this treatment, tax law imposes conditions: annual contribution limits, rules about who can contribute or deduct, and restrictions on when money can come out without penalty. The account itself is a wrapper, not an investment. What your IRA earns depends on what you hold inside it, whether that is a broad index fund, individual stocks, bonds, or cash. Understanding this separation between the account structure and the investments inside it is one of the most useful distinctions for a new investor to learn.

The two most widely discussed variants are the traditional IRA and the Roth IRA, and they differ mainly in the timing of taxes. A traditional IRA may offer a deduction on contributions, with withdrawals taxed later as ordinary income. A Roth IRA works in the opposite direction: contributions are made with after-tax money, and qualified withdrawals are generally not taxed. Other structures, such as IRAs designed for self-employed people and small businesses, follow different contribution rules. Eligibility for each type can depend on income and other factors. There is no single answer to which type is preferable; the trade-off rests on comparisons between current and expected future tax rates, which are inherently uncertain. Related definitions are available in the Glossary (/glossary), and the Education hub (/education) has deeper guides on each type.

Opening an IRA involves two layers of verification: the tax rules and the broker's account terms. For the tax side, confirm current contribution limits, income-based eligibility or deductibility thresholds, and withdrawal rules through official tax guidance or a qualified tax professional. For the broker side, read the institution's own current documents rather than third-party summaries. Check the fee schedule, account minimums, available investment types, transfer and closing fees, and how customer service handles retirement accounts. Do not assume any broker offers a specific feature until you see it confirmed in that broker's current disclosures. If you want a structured way to compare institutions on these points, the Find my broker tool (/find-my-broker) turns the checklist into a research workflow.
