How Much You Can Put Into a SIMPLE IRA Each Year

Your annual contribution limit depends on your age and income

The amount you can contribute to a SIMPLE IRA is set by the IRS each year and applies to all SIMPLE IRAs you own combined. For 2024, you can contribute up to $16,000 if you are under 50. If you are 50 or older, you can add an extra $3,500 "catch-up" contribution, bringing your total to $19,500. These limits change annually—the IRS adjusts them for inflation in $500 increments.

Your contribution limit is based only on your age, not on how much you earn. However, you cannot contribute more than your total compensation for the year. If you earned $12,000 in 2024, you cannot contribute $16,000 even though the limit allows it.

Your employer may also contribute to your SIMPLE IRA. Those employer contributions do not count against your personal limit, but they do count toward the total annual limit for all contributions combined (employer plus employee). The combined limit for 2024 is $61,000, or $68,000 if you are 50 or older.

Key Takeaways

• For 2024, you can contribute up to $16,000 to your SIMPLE IRA if you are under 50, or $19,500 if you are 50 or older.
• Your contribution cannot exceed your total compensation for the year, even if the IRS limit is higher.
• Employer contributions to your SIMPLE IRA do not count against your personal limit but do count toward the combined annual limit.
• The IRS adjusts contribution limits each year for inflation, usually in $500 increments.

How the catch-up contribution works if you are 50 or older

The catch-up contribution is an extra $3,500 per year available only to people who reach age 50 by December 31 of that tax year. You do not need to request it or fill out a special form—you simply contribute the additional amount to your SIMPLE IRA. Your employer and plan administrator should be aware you are using the catch-up, but the contribution itself is straightforward.

The catch-up amount is separate from the base limit. If you are 50 in 2024, your base limit is $16,000 and your catch-up is $3,500, for a total of $19,500. If you turn 50 in 2025, you can use the catch-up starting in 2025, not retroactively for 2024.

What happens if you contribute more than the limit

If you contribute more than the IRS limit in a single year, the excess amount is called an "excess contribution." You must withdraw the excess and any earnings on it by the tax-filing deadline (usually April 15 of the following year). If you do not withdraw it, you owe a 6% excise tax on the excess for each year it remains in the account.

Excess contributions can happen if you have multiple SIMPLE IRAs or if you miscalculate your compensation. For example, if you contributed $16,000 to one SIMPLE IRA and then opened another and contributed $2,000, your total is $18,000—$2,000 over the limit. You would need to withdraw that $2,000 plus any earnings it generated.

Employer contributions and how they affect your limit

Your employer can make two types of contributions to your SIMPLE IRA: a matching contribution or a non-elective contribution. A matching contribution means your employer matches a percentage of what you contribute (up to 3% of your salary). A non-elective contribution means your employer contributes a fixed percentage (usually 2%) regardless of whether you contribute.

These employer contributions do not reduce your personal $16,000 (or $19,500) limit. You can still contribute your full amount even if your employer is also contributing. However, the combined total of your contributions plus your employer's contributions cannot exceed $61,000 for 2024 (or $68,000 if you are 50 or older). In practice, this combined limit rarely affects employees because employer contributions are usually modest.

How to track your contributions across multiple accounts

If you have more than one SIMPLE IRA—perhaps from a previous job or because you opened one on your own—your contributions to all of them count toward the same annual limit. You must add them together to make sure you do not exceed $16,000 (or $19,500 if you are 50 or older).

Your plan administrator or payroll department should track contributions made through your current employer. For any SIMPLE IRAs you opened on your own or inherited from a previous job, you are responsible for tracking those contributions yourself. Many people use a spreadsheet or ask their financial institution for a year-end statement showing total contributions.

If you realize mid-year that you are on track to exceed the limit, contact your plan administrator or payroll department and ask them to stop withholding contributions for the remainder of the year. It is easier to prevent an excess contribution than to fix one after the fact.

Contribution deadlines and how to make contributions

Employee contributions are usually made through payroll deduction—your employer withholds money from your paycheck and deposits it into your SIMPLE IRA. These contributions must be deposited into your account within 30 days of the end of the month in which they were withheld. Your employer handles this automatically.

If you are self-employed and have a SIMPLE IRA, you make contributions yourself. Employee deferrals (the money you contribute from your own compensation) must be deposited by the tax-filing deadline for that year, usually April 15. Employer contributions have the same deadline. Check with your financial institution or plan administrator for their specific cutoff dates, as some may require deposits earlier.

Frequently Asked Questions

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

No. A SIMPLE IRA is designed for small businesses and self-employed people who do not have access to a 401(k). If your employer offers a 401(k), you cannot have a SIMPLE IRA through that employer. However, you can have a SIMPLE IRA from one job and a 401(k) from another job, though the contribution limits work together across both accounts.

What if my income drops mid-year and I have already contributed the full amount?

You can still keep the contributions you made. The rule is that you cannot contribute more than your total compensation for the year, but if you contributed based on expected income and your income dropped, you do not have to withdraw the excess. However, if you contributed more than you actually earned, you should withdraw the excess to avoid the 6% penalty.

Do I have to contribute the same amount every year?

No. Your contribution can vary from year to year based on your income and financial situation. One year you might contribute $10,000, and the next year $16,000. There is no requirement to contribute a minimum or to match what you contributed before.

Can my employer refuse to let me contribute the full limit?

No. Federal law requires that employers allow employees to contribute up to the IRS limit. Your employer can set a lower limit on matching contributions (such as matching only up to 2% instead of 3%), but they cannot prevent you from contributing your full $16,000 or $19,500 in employee deferrals.

What if I contribute too much by accident—how do I fix it?

Contact your plan administrator or financial institution and ask them to withdraw the excess contribution plus any earnings on it. You must do this by the tax-filing deadline (usually April 15 of the following year). Report the withdrawal on your tax return. If you miss the deadline, you owe a 6% excise tax on the excess for each year it stays in the account.
