Annual contribution limits for SIMPLE IRAs in 2024

For 2024, you can contribute up to $16,000 per year to a SIMPLE IRA if you are under age 50. If you are 50 or older, you can contribute an additional $3,500 catch-up amount, for a total of $19,500. These limits apply to employee deferrals — money you choose to have withheld from your paycheck.

Your employer may also contribute to your SIMPLE IRA. Employer contributions work differently and have their own rules, which are separate from what you personally defer. The limit on your own contributions does not include what your employer adds.

These numbers change each year. The IRS adjusts contribution limits for inflation, usually in $500 increments. If you are planning ahead, check the current year's limit before you set up payroll withholding, because the number you see this year may not be the same next year.

Key Takeaways

  • Employee deferrals to a SIMPLE IRA are capped at $16,000 for 2024 (or $19,500 if you are 50 or older), and this limit resets each calendar year.
  • Employer contributions are separate from your personal deferrals and do not count toward your individual limit.
  • The IRS adjusts these limits annually for inflation, so the amount you can contribute may change from year to year.
  • If you contribute more than the annual limit, the excess is subject to tax and a 6% penalty each year it remains in the account.
  • You must stop contributions in the year you reach your plan's retirement age, even if you are still working.

What happens if you contribute too much

If you defer more than the annual limit, the excess amount is taxed twice: once as ordinary income in the year you contributed it, and again as a 6% excise tax on the excess that remains in the account each subsequent year. This penalty continues until the excess is removed or corrected.

The IRS calls this the excess contribution tax. It applies whether you went over the limit intentionally or by mistake. If your employer withheld too much, you can request a correction, but you will need to act quickly — most plans have a window of a few months to fix errors before the tax kicks in.

If you have multiple SIMPLE IRAs (for example, from different employers in the same year), your contributions to all of them combined cannot exceed the annual limit. You are responsible for tracking the total across all accounts.

Employer contributions and how they work

Your employer can contribute to your SIMPLE IRA in two ways: a matching contribution or a non-elective contribution. A matching contribution means your employer puts in a percentage of what you defer — typically 1% to 3% of your salary. A non-elective contribution means your employer contributes a flat percentage of your salary to everyone's account, whether or not you defer anything yourself.

Employer contributions do not reduce your personal contribution limit. If you defer $16,000 and your employer contributes $2,000, you have not exceeded the limit — you have simply used your full $16,000 and received an additional $2,000 from your employer. The employer's money is separate.

However, there is a combined limit on total contributions to a SIMPLE IRA. The total of your deferrals plus your employer's contributions cannot exceed $69,000 for 2024 (or $86,500 if you are 50 or older and your employer allows catch-up contributions). In practice, this combined limit rarely affects employees because employer contributions are usually small.

Catch-up contributions if you are 50 or older

If you turn 50 at any point during the calendar year, you become may be able to access for catch-up contributions for that entire year. The catch-up amount for 2024 is $3,500, which you can defer in addition to the standard $16,000 limit. This brings your total to $19,500.

You do not need to wait until your birthday to start making catch-up contributions. Once you reach age 50, you can increase your payroll withholding for the remainder of that year and any year after. Your employer's payroll system will need to know your age to process the higher withholding correctly.

Catch-up contributions are optional. If you do not want to contribute the extra $3,500, you can stick with the standard $16,000 limit. There is no requirement to use the catch-up provision.

Contribution limits if you change jobs mid-year

If you work for multiple employers in the same calendar year, your total deferrals across all SIMPLE IRAs cannot exceed the annual limit. For example, if you defer $10,000 at your first job and then move to a second job, you can only defer $6,000 at the new employer (assuming the 2024 limit of $16,000).

You are responsible for tracking your total contributions across all accounts. Your employers do not automatically know what you contributed elsewhere. If you go over the limit, you will owe the excess contribution tax unless you correct it quickly.

When you leave a job, you can roll your SIMPLE IRA balance into another SIMPLE IRA or, after a two-year holding period, into a traditional IRA or 401(k). Rolling the money does not change your contribution limit for that year — it only moves the existing balance to a new account.

How contributions reduce your taxable income

Money you defer into a SIMPLE IRA is withheld from your paycheck before income tax is calculated. This means your contributions lower your taxable income for the year. If you defer $16,000, your employer reports your income to the IRS as $16,000 less than what you actually earned.

This tax break applies only to the money you personally defer, not to employer contributions. Employer contributions also reduce your taxable income, but they are handled separately on your tax return. The combined effect is that both your deferrals and your employer's contributions reduce the income you owe federal income tax on.

When you withdraw money from the SIMPLE IRA in retirement, you will owe income tax on the full amount withdrawn — both your contributions and the earnings, plus any employer contributions. The tax deferral is temporary; you pay the tax later, not never.

Rules for withdrawals before retirement

SIMPLE IRAs have strict rules about early withdrawals. If you withdraw money before age 59½, you generally owe a 10% early withdrawal penalty on top of ordinary income tax. However, there are a few exceptions: withdrawals for disability, medical expenses above a certain threshold, or a series of substantially equal payments over your lifetime.

There is also a two-year holding period that applies only to SIMPLE IRAs. If you withdraw money within two years of first participating in the plan, the early withdrawal penalty jumps to 25% instead of 10%. After two years, the standard 10% penalty applies (if you are under 59½).

You cannot borrow from a SIMPLE IRA the way you can from some 401(k) plans. Withdrawals are permanent — once the money comes out, it is out, and you cannot put it back except through a rollover to another SIMPLE IRA or, after two years, to a traditional IRA.

Frequently Asked Questions

Can I contribute to a SIMPLE IRA and a 401(k) in the same year?

No. If your employer offers a 401(k), you cannot also have a SIMPLE IRA with that same employer. However, if you work for two different employers — one with a SIMPLE IRA and one with a 401(k) — you can contribute to both, but your total deferrals across both accounts cannot exceed the annual limit for each plan type.

What if my employer does not make contributions?

Employer contributions are optional in most cases. Your employer can choose to make matching contributions, non-elective contributions, or neither. If your employer makes no contributions, you can still defer up to the annual limit from your own paycheck. Check your plan documents or ask your HR department what your employer's contribution policy is.

Do SIMPLE IRA contributions affect my Social Security benefits?

No. SIMPLE IRA contributions do not reduce your Social Security benefits. They reduce your taxable income for federal income tax purposes, but Social Security benefits are calculated based on your earnings record, not on how much you defer into retirement accounts.

Can I make contributions after I retire?

No. You can only contribute to a SIMPLE IRA while you are employed by the company that sponsors the plan. Once you leave the job or retire, you can no longer make deferrals. You can roll the balance into another account, but you cannot add new money to the SIMPLE IRA itself.

What if I miss the deadline to set up a SIMPLE IRA?

SIMPLE IRAs must be set up by October 1 of the year you want to start contributions. If you miss this deadline, you cannot establish the plan until the following year. Your employer can request a late-filing waiver from the IRS in some cases, but this is rare and requires a specific reason.
