How a SIMPLE IRA Differs From a Traditional IRA

The main difference: who can open one and how much you can contribute

A straightforward IRA and a traditional IRA are not the same thing, though both are retirement accounts where your money grows tax-deferred. The biggest difference is who can open each one. A traditional IRA is open to anyone with earned income. A straightforward IRA is only for self-employed people and small business owners — specifically, employers with 100 or fewer employees who want to offer retirement savings to their staff.

The contribution limits are also different. For 2024, you can put up to $7,000 per year into a traditional IRA (or $8,000 if you're 50 or older). With a straightforward IRA, the employee contribution limit is $16,000 per year (or $19,500 if you're 50 or older), but that's because employers are expected to contribute too. If you're self-employed and setting up a straightforward IRA for yourself, you can contribute as both employee and employer, which is why the total can be higher.

Key Takeaways

A traditional IRA is available to anyone with earned income, while a straightforward IRA is only for self-employed people and small business owners with 100 or fewer employees.
straightforward IRAs have higher contribution limits because employers are required to make matching or non-elective contributions on behalf of employees.
Both accounts offer tax-deferred growth, but the tax treatment of contributions and withdrawals works the same way in each.
A straightforward IRA has a two-year waiting period before you can roll funds into another retirement account without penalty, while a traditional IRA has no such restriction.
If you leave a job with a straightforward IRA, you can roll it into a traditional IRA after the two-year period ends.

Employer contributions: the feature that sets straightforward IRAs apart

The reason straightforward IRAs exist is to give small employers a way to offer retirement benefits without the complexity and cost of a 401(k). With a traditional IRA, the employee decides how much to save, and the employer has no role. With a straightforward IRA, the employer must contribute money on behalf of each employee who participates.

The employer has two choices: either match what the employee contributes (up to 3 percent of their salary), or make a non-elective contribution of 2 percent of salary for every employee, whether they contribute or not. This is a real cost to the business, which is why straightforward IRAs are designed for small operations. If you're self-employed and opening a straightforward IRA for yourself, you wear both hats — you contribute as an employee and as an employer.

Tax treatment: both accounts work the same way

In both a straightforward IRA and a traditional IRA, the money you contribute reduces your taxable income for that year (assuming you don't have a workplace 401(k) or other retirement plan). When you withdraw the money in retirement, those withdrawals are taxed as ordinary income. If you withdraw money before age 59½, you generally owe a 10 percent early withdrawal penalty plus income tax on the amount withdrawn.

The tax-deferred growth inside the account works identically too. You don't pay tax on investment gains, dividends, or interest while the money sits in the account. You only pay tax when you take the money out. This is the same whether you're using a traditional IRA or a straightforward IRA.

The two-year rule: a straightforward IRA restriction that traditional IRAs don't have

Here's a rule that applies only to straightforward IRAs: if you withdraw money or roll it into another account within two years of opening the straightforward IRA, you owe a 25 percent penalty on the amount moved (instead of the usual 10 percent early withdrawal penalty). This two-year window starts from the date you first contributed to the account.

This rule exists because straightforward IRAs are meant to be long-term retirement savings vehicles. After two years, you can roll a straightforward IRA into a traditional IRA or another retirement account without this extra penalty. A traditional IRA has no such waiting period — you can roll it or transfer it whenever you want, though you still follow the standard rollover rules.

When you might choose each account

If you're an employee at a company with 100 or fewer people, your employer might offer a straightforward IRA instead of a 401(k) because it's simpler and cheaper to administer. If you're self-employed or own a small business, you might open a straightforward IRA to save for retirement and offer the same benefit to any employees you hire. The higher contribution limits make it attractive if you want to save more than a traditional IRA allows.

If you're an employee at a larger company or you work for yourself without employees, a traditional IRA is usually your option. You can also have both — a straightforward IRA through your employer and a traditional IRA in your own name, though contribution limits explore across both accounts combined.

Rolling over a straightforward IRA to a traditional IRA

If you leave a job where you had a straightforward IRA, you have options. You can leave the money in the straightforward IRA, roll it into a new straightforward IRA if your new employer offers one, or roll it into a traditional IRA. The key timing rule: you must wait two years from when you first contributed to the straightforward IRA before rolling it into a traditional IRA without the 25 percent penalty.

After the two-year window closes, the rollover process is straightforward. You contact the financial institution holding your straightforward IRA and request a direct rollover to a traditional IRA at another institution. The money moves directly between accounts, and you don't touch it — this avoids any tax withholding or additional penalties. You can also do a 60-day rollover where you receive the check and deposit it yourself, but the direct rollover is simpler and safer.

Frequently Asked Questions

Can I have both a straightforward IRA and a traditional IRA at the same time?

Yes, you can have both accounts open simultaneously. However, your total contributions across all traditional and SEP IRAs in a given year cannot exceed the traditional IRA limit ($7,000 in 2024, or $8,000 if you're 50 or older). Contributions to a straightforward IRA are separate and don't count toward this limit.

What happens to my straightforward IRA if I leave my job?

Your straightforward IRA stays yours. You can leave the money where it is, roll it into a new straightforward IRA if your new employer offers one, or roll it into a traditional IRA (after the two-year waiting period). You control the account and the money regardless of your employment status.

Is a straightforward IRA better than a traditional IRA?

Neither is universally better — they serve different situations. A straightforward IRA makes sense if you're self-employed or work for a small employer that offers one, because the higher contribution limits and employer match help you save more. A traditional IRA is the standard choice for employees at larger companies or anyone self-employed without employees.

Can I withdraw money from a straightforward IRA before retirement?

You can withdraw money, but you'll owe income tax on the amount plus a 10 percent penalty if you're under 59½. If you withdraw within two years of opening the account, the penalty jumps to 25 percent. After age 59½, you can withdraw without penalty, though you still owe income tax.

What's the difference in investment options between the two?

Both straightforward IRAs and traditional IRAs can hold the same types of investments: stocks, bonds, mutual funds, and ETFs. The investment options depend on where you open the account, not on the account type itself. Some financial institutions offer more choices than others, regardless of whether it's a straightforward or traditional IRA.
