401(k) vs. IRA: Which Retirement Account Should You Use First?
Both accounts offer valuable tax breaks for retirement savings, but they work differently — and the right order to use them isn't always obvious.
Two accounts, one goal
A 401(k) and an IRA (individual retirement account) both exist to do the same basic thing: let you invest for retirement while receiving a tax advantage for doing so. Where they differ is who sets the account up and what rules come attached.
The employer connection
A 401(k) is sponsored by an employer, who selects the plan provider and the menu of investment options you can choose from — typically a set of mutual funds or target-date funds. Contributions come directly out of your paycheck before you ever see the money. Many employers also offer a matching contribution, adding money to your account, usually up to a percentage of your salary, when you contribute yourself.
An IRA, by contrast, is opened independently at a brokerage of your choosing, with no employer involved. That means far more control over what you invest in — effectively any stock, bond, or fund the brokerage offers — but no employer match, since there's no employer in the picture.
Traditional vs. Roth: same accounts, different tax timing
Both 401(k)s and IRAs come in two main tax flavors. A traditional account gives you a tax deduction on contributions today, and you pay ordinary income tax when you withdraw the money in retirement. A Roth account offers no upfront deduction — contributions are made with after-tax money — but qualified withdrawals in retirement, including all the growth, come out completely tax-free.
- Traditional accounts tend to favor people who expect to be in a lower tax bracket in retirement than they are now.
- Roth accounts tend to favor people who expect to be in the same or a higher tax bracket in retirement, or who simply value tax-free withdrawals later.
- Contribution limits, income eligibility rules, and required withdrawal rules differ between the account types and change periodically, so it's worth checking current figures before contributing.
A common-sense order of operations
A widely used rule of thumb goes like this: contribute enough to your 401(k) to get the full employer match first, since that's an immediate, guaranteed return on your money. After that, consider contributing to an IRA, since it typically offers a wider range of low-cost investment choices than a workplace plan. If you max out the IRA and still have more to save, return to the 401(k) and continue contributing there.
An employer match is one of the only places in personal finance where you're handed free money for doing something you were probably going to do anyway.
You don't have to choose only one
These accounts aren't mutually exclusive — many people contribute to both a 401(k) and an IRA in the same year, up to each account's own contribution limit. The "which one first" question is really a question of sequencing your savings for maximum benefit, not picking a single winner.
