SIMPLE IRA vs. Traditional IRA: Contributions, Taxes, Withdrawals

A SIMPLE IRA is an employer-sponsored workplace retirement plan with mandatory employer contributions and high salary-deferral limits, while a Traditional IRA is a personal account you open and fund on your own. When comparing a SIMPLE IRA vs. a Traditional IRA, the practical differences come down to who can use each account, how much you can contribute, how the tax treatment works, what happens if you pull money out early, and how easily you can move funds between accounts.

Who Can Open Each Account

A Traditional IRA is available to anyone with taxable compensation, such as wages, salaries, commissions, self-employment income, or tips.¹ Having a workplace retirement plan doesn’t disqualify you, and since 2020 there is no upper age limit on contributions.

A SIMPLE IRA isn’t something you open on your own. Your employer has to sponsor it, and the business must have 100 or fewer employees who each earned at least $5,000 in the prior year. As an employee, you qualify to participate if you earned at least $5,000 during any two prior calendar years and expect to earn that much again in the current year.² The employer chooses the financial institution and sets the plan up; you decide whether to defer part of your paycheck into it.

2026 Contribution Limits

The contribution gap between these two accounts is large. For 2026, you can put up to $7,500 into a Traditional IRA. The employee deferral limit for a SIMPLE IRA is $17,000.³ Neither figure includes what your employer contributes on top.

The gap reflects how each account is designed to work: a SIMPLE IRA is meant to serve as an employee’s main retirement plan, while a Traditional IRA is a supplemental personal account.

Catch-Up Contributions If You’re 50 or Older

Both accounts allow extra contributions at 50 and above. In 2026, the Traditional IRA catch-up is $1,100, bringing your total limit to $8,600. The SIMPLE IRA catch-up is $4,000 for ages 50 to 59 and 64 or older, raising the total to $21,000.³

Under SECURE 2.0, SIMPLE participants aged 60 through 63 get an even higher catch-up of $5,250 in 2026, for a total deferral of $22,250. Traditional IRAs don’t have this enhanced tier.

Some SIMPLE plans maintained by smaller employers use a higher deferral limit of $18,100 for 2026 instead of $17,000. Whether your plan qualifies depends on its structure and the size of the business.

When You Have to Contribute

You can fund a Traditional IRA for a given tax year up until your tax return filing deadline, typically April 15 of the following year, not counting extensions.¹ SIMPLE IRA salary deferrals work differently. They come out of your paychecks during the calendar year itself. Employer matching or nonelective contributions have to be deposited by the business’s tax return deadline, including extensions.⁴

How Contributions Are Taxed

SIMPLE IRA employee contributions are pre-tax. The money comes out of your paycheck before income tax is calculated, so every dollar you defer reduces that year’s taxable income. There are no income-based limits on this. Starting with plan years after 2022, employers can also offer a Roth version of the SIMPLE deferral, letting you contribute after-tax dollars that grow tax-free.⁵

Traditional IRA contributions are more complicated. Whether you can deduct them depends on whether you or your spouse have access to a workplace retirement plan and how much you earn. If neither of you is covered by a workplace plan, your full Traditional IRA contribution is deductible no matter your income. If one of you is covered, deductions phase out at these 2026 income ranges:³

Single filer covered by a workplace plan: $81,000 to $91,000
Married filing jointly, contributor covered: $129,000 to $149,000
Married filing jointly, contributor not covered but spouse is: $242,000 to $252,000
Married filing separately, covered: $0 to $10,000

Even if your income runs above these thresholds, you can still contribute to a Traditional IRA on a nondeductible basis. You’ll need to file Form 8606 to keep track of the after-tax portion, so it isn’t taxed again when you withdraw it.

Employer Contributions

This is one of the sharpest differences between the two accounts. A SIMPLE IRA requires the employer to contribute every year using one of two formulas:⁶

A dollar-for-dollar match on each participating employee’s deferrals, up to 3% of the employee’s compensation.
A flat 2% nonelective contribution for every eligible employee, whether or not they defer any of their own pay.

All employer contributions vest immediately, so the money is yours the moment it lands in the account. A Traditional IRA involves no employer at all; you fund it yourself.

Early Withdrawals and the SIMPLE Two-Year Rule

Take money out of either account before age 59½ and you’ll owe ordinary income tax on the distribution plus a 10% additional tax.⁷

SIMPLE IRAs carry a harsher penalty at the start. During the first two years of your participation, the additional tax on early withdrawals is 25%, not 10%.⁸ The clock starts on the date your employer first deposited money into your account, not the date you signed up. After two years, the penalty drops to the standard 10%.

Both account types share the usual exceptions to the 10% penalty, including total and permanent disability, up to $10,000 for a first-time home purchase, qualified higher education expenses, unreimbursed medical costs above 7.5% of your adjusted gross income, health insurance premiums while unemployed, up to $5,000 per child for a birth or adoption, and substantially equal periodic payments. During the SIMPLE two-year window, though, the 25% rate still applies even for many of these exceptions unless the specific exception waives it.

Moving Money Out

Traditional IRAs give you wide rollover freedom. You can do unlimited trustee-to-trustee transfers between IRAs, and you can roll funds into a 401(k) or other qualified plan. If the money passes through your hands (an indirect rollover), you have 60 days to redeposit it, and you’re limited to one indirect IRA rollover across all your IRAs in any 12-month period.⁹

SIMPLE IRAs lock you in for the first two years. During that window, you can only roll or transfer funds into another SIMPLE IRA.⁸ Moving money to a Traditional IRA, 401(k), or any other non-SIMPLE account before the two years are up is treated as a taxable distribution and triggers the 25% additional tax. Once you’re past the two-year mark, your SIMPLE funds get the same rollover options as a Traditional IRA.⁶

Required Minimum Distributions

Both accounts follow the same rule here: you must start taking required minimum distributions at age 73.¹⁰ The first one is due by April 1 of the year after you turn 73, and each one after that by December 31. Missing the required amount brings a 25% excise tax on the shortfall, dropping to 10% if you fix it within two years.¹¹
