How a SIMPLE IRA Works: Contributions, Withdrawals, and Tax Treatment

A SIMPLE IRA lets you and your employer each put money into a retirement account with lower paperwork than a 401(k)

A SIMPLE IRA (Savings Incentive Match Plan for Employees) is a retirement account that small employers set up for their workers. You contribute a portion of your paycheck before taxes, your employer adds matching money or a flat contribution, and the account grows tax-deferred until you withdraw it in retirement. The main appeal is simplicity: employers avoid the complex rules and annual testing that come with 401(k) plans, and you get a straightforward way to save with employer help.

The account itself works like a traditional IRA—your contributions reduce your taxable income for the year, and you pay income tax on withdrawals in retirement. But the contribution limits are higher than a regular IRA, and your employer's matching contributions are mandatory (though the match itself is small). If you work for a company with 100 or fewer employees, your employer may have chosen a SIMPLE IRA instead of a 401(k).

Key Takeaways

• You contribute a percentage of your salary through payroll deduction, and your employer must match that amount dollar-for-dollar up to 3 percent of your pay, or contribute 2 percent for all workers regardless of whether they contribute.
• For 2024, you can contribute up to $16,000 per year to a SIMPLE IRA, or $19,500 if you are 50 or older (these limits change annually).
• Money in a SIMPLE IRA grows tax-deferred, and you pay income tax on withdrawals after age 59½, just as you would with a traditional IRA.
• Withdrawals before age 59½ trigger a 25 percent penalty if you withdraw within the first two years of opening the account, or 10 percent after that, plus income tax on the full amount.
• You cannot roll a SIMPLE IRA into a regular IRA or 401(k) until you have held it for at least two years.

How contributions work: yours and your employer's

You decide what percentage of your paycheck to contribute—your employer deducts it automatically and deposits it into your SIMPLE IRA. There is no required minimum, but you cannot contribute more than the annual limit. For 2024, that limit is $16,000 per year; if you are 50 or older, you can contribute an additional $3,500 as a catch-up contribution, for a total of $19,500. These limits change each year based on inflation.

Your employer must then add money to your account. They have two choices: match your contributions dollar-for-dollar up to 3 percent of your salary, or contribute 2 percent of your salary for every employee, whether or not that employee contributes. Most employers choose the match because it costs less if some workers do not contribute. If you earn $50,000 and contribute 3 percent ($1,500), your employer matches $1,500. If you contribute nothing, your employer contributes nothing under the match option—but if they chose the 2 percent option instead, they would contribute $1,000 regardless.

Both your contributions and your employer's contributions are deposited into the same account. The money is yours immediately—there is no vesting period, unlike some 401(k) plans. You own every dollar from day one.

Tax treatment: how contributions and withdrawals are taxed

Your contributions to a SIMPLE IRA reduce your taxable income for the year. If you contribute $10,000, you report $10,000 less in income to the IRS. Your employer's contributions are also tax-free to you in the year they are made—you do not report them as wages. This is why the account is attractive: you lower your tax bill today while saving for retirement.

The money inside the account grows without being taxed each year. If your balance earns $2,000 in interest or investment gains, you do not pay tax on that $2,000 until you withdraw it. This tax deferral is what allows the account to compound over decades.

When you withdraw money in retirement, you pay ordinary income tax on the full amount—your contributions, your employer's contributions, and all the growth. If you withdraw $100,000 at age 65 and you are in the 22 percent tax bracket, you owe $22,000 in federal income tax on that withdrawal. State income tax may apply as well, depending on where you live.

Withdrawal rules and early-withdrawal penalties

You can withdraw money from your SIMPLE IRA anytime, but the IRS penalizes early withdrawals. If you withdraw before age 59½, you owe a 10 percent penalty on the amount withdrawn, plus income tax. So a $10,000 withdrawal at age 45 costs you $1,000 in penalty plus income tax on the full $10,000.

The penalty is steeper in the first two years. If you withdraw within two years of opening the account, the penalty jumps to 25 percent instead of 10 percent. This rule discourages people from treating the SIMPLE IRA as a short-term savings account. After two years, the penalty drops to the standard 10 percent.

There are a few exceptions where you can withdraw without penalty: disability, death (your beneficiary can withdraw), a series of substantially equal periodic payments (a complex IRS calculation), or a may have access to disaster. Medical expenses above 7.5 percent of your adjusted gross income are not an exception—the 10 percent penalty still applies, though you can deduct the medical expenses separately on your tax return.

At age 73, you must begin taking required minimum distributions (RMDs) from your SIMPLE IRA. The IRS calculates the amount based on your age and account balance, and you must withdraw at least that amount each year or face a 25 percent penalty on the shortfall (this penalty was reduced from 50 percent in 2023). You can withdraw more than the minimum without penalty.

Rolling over a SIMPLE IRA to another account

You cannot move money from a SIMPLE IRA to a regular IRA or a 401(k) until you have held the SIMPLE IRA for at least two years. This two-year rule is specific to SIMPLE IRAs and stricter than regular IRAs. Once two years have passed, you can roll the balance into a traditional IRA, a Roth IRA (though you would owe taxes on the conversion), or a 401(k) if your new employer offers one.

A rollover is a direct transfer from one account to another—the money never touches your hands. Your bank or brokerage handles the paperwork. If you withdraw the money yourself and deposit it within 60 days, it counts as a rollover and avoids taxes and penalties, but if you miss the 60-day window, the IRS treats it as a taxable withdrawal.

If you leave your job, you can leave the SIMPLE IRA where it is, roll it to an IRA at a different institution, or roll it to your new employer's plan if they allow it. There is no rush—you have as long as you need to decide, as long as you do not withdraw the money.

SIMPLE IRA vs. a regular IRA: key differences

A regular IRA is an account you open and fund yourself; a SIMPLE IRA is set up by your employer and funded through payroll. The contribution limit for a regular IRA in 2024 is $7,000 per year ($8,000 if you are 50 or older), while a SIMPLE IRA allows $16,000 ($19,500 with catch-up). If you have a SIMPLE IRA through your employer, you cannot also contribute to a regular IRA in the same year—the limits are combined.

A SIMPLE IRA also has the two-year rollover restriction and the steeper 25 percent early-withdrawal penalty in the first two years. A regular IRA does not have these rules. On the other hand, a SIMPLE IRA comes with employer matching contributions, which a regular IRA does not. If your employer offers a SIMPLE IRA, you are getting assistance programs in the form of the match, which makes it more valuable than a regular IRA even with the stricter rules.

If you are self-employed, you cannot use a SIMPLE IRA—you would use a Solo 401(k) or a SEP IRA instead. SIMPLE IRAs are only for employees of small businesses.

What happens to your SIMPLE IRA if you change jobs

When you leave your job, your SIMPLE IRA stays in your name and remains yours to manage. Your employer has no further claim to it. You can leave it with the current custodian (the bank or brokerage holding it), move it to a new custodian, or roll it into your new employer's retirement plan if they offer one and accept rollovers.

If your new employer also has a SIMPLE IRA, you can roll your old one into the new one, but only after two years have passed since you opened the first account. If less than two years have passed, you must either leave the old account open or roll it into a regular IRA (which triggers the two-year clock to reset). Many people leave old SIMPLE IRAs open at their original custodian to avoid complications.

If your new employer offers a 401(k) instead of a SIMPLE IRA, you can roll your SIMPLE IRA into it after two years. Before two years, rolling into a 401(k) is not permitted—you would have to wait or roll into a regular IRA first.

Frequently Asked Questions

Can I contribute to both a SIMPLE IRA and a regular IRA in the same year?

No. Your contributions to both accounts combined cannot exceed the SIMPLE IRA limit for that year. If you contribute $10,000 to a SIMPLE IRA, you cannot contribute to a regular IRA. However, your employer's contributions to the SIMPLE IRA do not count toward this limit—only your own contributions do.

What if my employer stops matching contributions?

Your employer can reduce or suspend the match, but they must notify you in writing at least 30 days before the plan year ends. If they suspend the match for two consecutive years, they can then terminate the SIMPLE IRA entirely. The money already in your account remains yours and continues to grow tax-deferred.

Can I borrow from my SIMPLE IRA?

No. Unlike some 401(k) plans, SIMPLE IRAs do not allow loans. Your only option is to withdraw the money, which triggers the penalty and income tax. This is one reason a 401(k) can be more flexible if your employer offers one.

Do I have to contribute to my employer's SIMPLE IRA?

No, contributions are voluntary. However, if your employer chose the 2 percent non-elective contribution option instead of matching, they contribute 2 percent of your salary whether or not you contribute anything. If they chose the match option, you only receive employer money if you contribute yourself.

What happens to my SIMPLE IRA if I become disabled?

You can withdraw money from your SIMPLE IRA without the 10 percent early-withdrawal penalty if you become disabled, as defined by the IRS (unable to engage in any substantial gainful activity). You still owe income tax on the withdrawal, but not the penalty. You must provide documentation of your disability to your account custodian.
