How Much You Can Put Into a SIMPLE IRA Each Year

Annual contribution limits for SIMPLE IRAs in 2024

For 2024, you can contribute up to $16,000 to a SIMPLE IRA if you are an employee. If you are self-employed or a business owner, you can contribute up to $16,000 as an employee deferral, plus an additional employer contribution. The IRS adjusts these limits annually for inflation, so the figure changes most years.

These limits apply to the total across all SIMPLE IRAs you own. If you work for two employers who both offer SIMPLE IRAs, your combined employee deferrals cannot exceed the annual limit. The employer contribution portion, however, is separate and does not count toward your personal limit.

Key Takeaways

• Employee deferrals are capped at $16,000 for 2024, and this limit applies across all SIMPLE IRAs you contribute to, even if you have multiple employers.
• Employers must contribute either a matching contribution (up to 3 percent of your salary) or a non-elective contribution (2 percent of your salary for all may be able to access employees).
• If you are age 50 or older, you can make an additional catch-up contribution of $3,500 in 2024, raising your total to $19,500.
• Contributions are made through payroll deduction and are tax-deductible in the year you make them, reducing your taxable income.
• The IRS raises contribution limits every few years when inflation reaches certain thresholds, so check the current year's limit before you contribute.

How employer contributions work alongside your deferrals

Your employer's contribution is separate from what you defer from your paycheck. Employers must choose one of two paths: a matching contribution or a non-elective contribution.

With a matching contribution, your employer matches what you contribute, up to 3 percent of your compensation. If you earn $50,000 and contribute 3 percent ($1,500), your employer contributes $1,500. If you contribute only 1 percent ($500), your employer contributes only $500. Some employers set a lower match percentage, but it cannot exceed 3 percent unless the plan document says otherwise.

With a non-elective contribution, your employer contributes 2 percent of your salary for every may be able to access employee, regardless of whether you contribute anything yourself. On a $50,000 salary, that is $1,000 per year, whether you defer $0 or $16,000.

Catch-up contributions if you are 50 or older

If you reach age 50 before the end of the calendar year, you can make an additional catch-up contribution of $3,500 in 2024. This raises your total employee deferral limit to $19,500 for that year.

You do not need to ask permission or fill out a special form. Once you turn 50, you simply increase your payroll deferral election with your employer's plan administrator. The catch-up contribution is available only to employees, not to self-employed individuals, and it applies only to SIMPLE IRAs, not to other retirement accounts.

What happens if you contribute too much

If you exceed the annual limit—whether by accident or because you worked for multiple employers—you must withdraw the excess before your tax filing deadline (usually April 15 of the following year). The excess amount is taxable income in the year you contributed it, and you also owe a 6 percent excise tax on the overage for each year it remains in the account.

If you contributed too much because you worked for two employers and neither knew about the other, contact the plan administrator at your primary job first. They can help you figure out which account should retain the excess and which should return it. You will need to file Form 5329 with your tax return to report the overage and claim the correction.

Contribution deadlines and how payroll works

Employee deferrals happen automatically through payroll deduction throughout the year. You elect a percentage or dollar amount when you enroll, and your employer deducts it from each paycheck. There is no separate deadline—contributions are made as you earn the money.

Employer contributions must be deposited into the SIMPLE IRA by the tax filing deadline for that year, including extensions. If your employer files an extension on their business tax return, they have until October 15 to deposit the employer contribution for the prior year. Ask your plan administrator when your employer typically makes deposits so you know when to expect the money in your account.

How SIMPLE IRA contributions differ from 401(k) and traditional IRA limits

SIMPLE IRAs have lower contribution limits than 401(k) plans. A 401(k) allows up to $69,000 in total contributions (employee plus employer) in 2024, compared to a maximum of around $35,500 in a SIMPLE IRA (your $16,000 deferral plus a 3 percent employer match on a $50,000 salary). SIMPLE IRAs are designed for small businesses with 100 or fewer employees, so the lower limits reflect their simpler structure.

Traditional IRAs and Roth IRAs have much lower limits—$7,000 for 2024—and do not include employer contributions at all. If you have access to a SIMPLE IRA through your employer, you cannot also contribute to a traditional or Roth IRA in the same year, with limited exceptions. Check with a tax professional if you have both a SIMPLE IRA and an IRA outside of work.

Tax treatment of your contributions and withdrawals

Your employee deferrals reduce your taxable income in the year you contribute. If you defer $10,000 to a SIMPLE IRA, your W-2 wages are reduced by $10,000, lowering the income tax you owe that year. Employer contributions are also tax-free when deposited and do not appear as taxable wages on your W-2.

When you withdraw money in retirement, the entire amount—your contributions plus all earnings—is taxed as ordinary income. If you withdraw before age 59½, you owe a 10 percent early withdrawal penalty on top of income tax, unless an exception applies (disability, medical expenses, or a few other narrow cases). Withdrawals from a SIMPLE IRA are subject to required minimum distributions starting at age 73.

Frequently Asked Questions

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

No. If your employer offers a SIMPLE IRA, you cannot contribute to a 401(k) at the same employer. However, if you have a second job with a different employer that offers a 401(k), you can contribute to both plans, but your combined employee deferrals across all plans cannot exceed the annual limit for each plan type.

What if my employer does not make their required contribution?

Contact your plan administrator or HR department immediately. Employers are legally required to make either a matching or non-elective contribution. If your employer fails to do so, you may be able to file a complaint with the Department of Labor or consult an employment attorney about your options.

Do SIMPLE IRA contributions reduce my Social Security wages?

No. SIMPLE IRA deferrals reduce your federal income tax but do not reduce the wages reported to Social Security. Your full salary, including the amount you defer, counts toward your Social Security benefit calculation.

Can I roll over a SIMPLE IRA to a traditional IRA or 401(k)?

Yes, but only after you have been in the SIMPLE IRA for at least two years. If you roll over within the first two years, the distribution is taxed as income and subject to a 25 percent penalty (not the standard 10 percent). After two years, you can roll over to a traditional IRA or 401(k) without penalty.

What if I get a raise mid-year—does my contribution limit increase?

No. Your contribution limit is fixed for the calendar year, regardless of salary changes. However, your employer's matching contribution (if they use that method) is based on your actual compensation, so a raise increases the amount your employer contributes.
