An IRA — Individual Retirement Account — is a tax-advantaged account designed to help you save and invest for retirement. Unlike a workplace 401(k), you open an IRA yourself through a bank or brokerage, and you control what it invests in. The big appeal is the tax break: IRAs let your money grow with far less drag from taxes than an ordinary investment account.
There are two main types — Traditional and Roth — and the difference comes down to when you get the tax break. This guide explains how each works and how to decide between them.

How a Traditional IRA Works
With a Traditional IRA, you may be able to deduct your contributions from your taxable income in the year you make them, lowering your tax bill now. Your investments then grow tax-deferred, and you pay ordinary income tax on the money when you withdraw it in retirement.
- Tax break now: contributions may be tax-deductible, depending on your income and whether you have a workplace plan.
- Taxed later: withdrawals in retirement are taxed as ordinary income.
- Required withdrawals: you must start taking required minimum distributions (RMDs) at the age set by law.
How a Roth IRA Works
A Roth IRA flips the timing. You contribute after-tax money — no deduction today — but your investments grow tax-free, and qualified withdrawals in retirement are completely tax-free.
- No tax break now: contributions are made with money you’ve already paid tax on.
- Tax-free later: qualified withdrawals, including all the growth, are tax-free.
- More flexibility: you can generally withdraw your own contributions (not earnings) at any time without penalty, and Roth IRAs have no required minimum distributions during your lifetime.
Traditional vs. Roth: How to Choose
The key question is whether you expect to be in a higher or lower tax bracket in retirement than you are now:
- Choose Traditional if you expect your tax rate to be lower in retirement — you take the deduction now while your rate is high and pay tax later when it’s lower.
- Choose Roth if you expect your tax rate to be the same or higher in retirement, or you’re early in your career with years of tax-free growth ahead. Many younger savers favor Roth for this reason.
You don’t have to pick only one — some people contribute to both over time to hedge against an unknown future tax rate. Roth IRAs do have income limits that can reduce or block direct contributions at higher incomes, while Traditional IRA deductibility phases out for higher earners who also have a workplace plan.
Contribution and Withdrawal Basics
A few rules apply to both types of IRA:
- Annual limits: the IRS caps how much you can contribute each year (with a higher limit if you’re 50 or older). The exact figure changes periodically.
- Earned income required: you generally need earned income to contribute.
- Early-withdrawal penalty: taking money out before age 59½ can trigger a 10% penalty plus taxes — but there are penalty-free exceptions for things like a first-home purchase, qualified education costs, certain medical expenses, and more.
- Wide investment choice: within an IRA you can typically invest in stocks, bonds, mutual funds, ETFs, and more.
Why Start Early
The single biggest advantage of an IRA is time. Because gains compound — earnings generate their own earnings — money invested in your 20s or 30s has decades to grow. Starting early, even with small amounts, often matters more than the specific account type you choose.
Frequently Asked Questions
Can I have an IRA and a 401(k)?
Yes. Many people contribute to a workplace 401(k) and an IRA. Having a 401(k) can affect whether your Traditional IRA contributions are tax-deductible, but it doesn’t stop you from owning an IRA.
What happens if I withdraw money early?
Withdrawing earnings before age 59½ usually means a 10% penalty plus income tax, unless you qualify for an exception. With a Roth, you can withdraw your own contributions anytime tax- and penalty-free; the restrictions apply to the earnings.
How much can I contribute each year?
The IRS sets an annual contribution limit that applies across all your IRAs combined, with an extra “catch-up” amount once you’re 50 or older. Because the number is adjusted over time, check the current limit at IRS.gov before you contribute.
The Bottom Line
An IRA is one of the most powerful tools for building retirement savings, thanks to its tax advantages. A Traditional IRA gives you a tax break now and taxes withdrawals later; a Roth IRA does the opposite, offering tax-free withdrawals in retirement. Choose based on when you expect the tax break to help you most — and whichever you pick, the best time to start is as early as you can.
