Key takeaways

  1. Two IRAs. Two different roles. SIMPLE IRAs are employer‑sponsored, while Roth IRAs are individual accounts you open on your own.
  2. How you save—and how you’re taxed—differs. SIMPLE IRA contributions are pre‑tax and taxable later; Roth contributions are after‑tax with the potential for tax‑free withdrawals.
  3. Contribution limits vary widely. SIMPLE IRAs allow higher annual contributions, while Roth IRAs have lower limits and income restrictions.
  4. You don’t have to choose just one. If eligible, using both a SIMPLE IRA and a Roth IRA can help balance today’s tax savings with future flexibility.

If you have the option between contributing to a SIMPLE IRA vs. Roth IRA, it's important to understand how each works and the benefits they can provide. Both offer a tax-advantaged way to save for retirement, although the rules concerning contributions, taxation and distributions work differently for each.

Depending on your situation, you may want to choose one or the other, but it's also possible to use both. Read on to learn how these plans work so you can decide the best way to incorporate them into your retirement savings plan.

What are SIMPLE IRAs?

A Savings Incentive Match Plan for Employees individual retirement account, or SIMPLE IRA, is a retirement plan available through small business employers. It offers a convenient way for a business owner to contribute to both their own and their employees' retirement savings.

SIMPLE IRA eligibility

Your employer—or you if you're self-employed—creates and manages SIMPLE IRAs. Employers with fewer than 100 employees can sponsor a SIMPLE IRA plan as long as they don't have another type of retirement plan.

If your employer offers a SIMPLE IRA, you can participate if you earned $5,000 or more in any two prior years and expect to make at least that much in the current year. Your employer can allow you to participate if you don't meet those criteria, but they can't keep you from participating if you do.

SIMPLE IRA contributions & limits

SIMPLE IRAs are funded by a combination of employee and employer contributions. If your employer offers a SIMPLE IRA, they are required to make contributions on your behalf.

What are Roth IRAs?

Roth IRAs are individually owned retirement accounts that you can open at any financial institution that offers them. The hallmark of these accounts is their tax advantages: You fund them with dollars you've already paid taxes on, so you receive tax advantages later.

Roth IRA eligibility

While employers don't operate these plans, you do need to have the IRS definition of earned income to open one. You can't contribute things that don't qualify as earned income (such as interest, Social Security or dividends) to a Roth IRA.

Roth IRAs have income limits to participate. If you make more than the limit, your allowable contribution is reduced in phases until you reach the maximum, after which you can't contribute at all.

Taxation: SIMPLE vs. Roth IRAs

SIMPLE and Roth IRAs both offer tax benefits, but they do so differently. Here are the key points to know:

Taxation of contributions

  • SIMPLE IRA contributions aren't taxed. Your salary deferrals aren't included in your taxable income, which gives you a tax break for the year you make contributions.
  • Roth IRA contributions aren't tax-deductible. You don't get a tax deduction for Roth contributions. Your Roth IRA contributions are made with dollars you've already paid taxes on, and they're still included in your taxable income.

Taxation of withdrawals

All retirement accounts have specific rules surrounding qualified withdrawals, which means you won't face any penalties for withdrawing money from the account. We break down the specific rules below:

SIMPLE IRA

  • As a tax-deferred account, you're liable for income taxes when you withdraw from your SIMPLE IRA. Your full withdrawal is taxed at your marginal tax rate.
  • Withdrawals before you reach 59½ generally result in a 10% penalty on top of your regular income tax liability. If you withdraw from a SIMPLE IRA in the first two years after you start making contributions, the penalty is 25% rather than 10%.
  • The IRS requires you to start taking required minimum distributions (RMDs) by the time you turn 73. Failure to do so results in additional penalties.

Roth IRA

  • Since the taxes have been paid on them, you can withdraw your contributions at any time without facing additional taxes or penalties.
  • However, if you make a withdrawal from the account before age 59½ that reaches beyond your contributions and taps into your earnings, the earnings portion will be subject to both income taxes and a 10% penalty.
  • There are no required minimum distributions at any point for the original account owner. However, inherited Roth IRAs will be subject to RMDs.

Which is better, a Roth IRA or SIMPLE IRA?

Neither retirement account is fundamentally a better choice than the other. You have to consider how the features of each fit into your particular financial strategy. But these are some general considerations to guide your decision-making:

  • SIMPLE IRAs have higher contribution limits, provide an immediate tax deduction and allow you to receive employer contributions. These features could allow you to save more for retirement.
  • Roth IRAs have relatively low contribution limits, and you may not be able to contribute at all if your income is too high. But they grow tax-free, which could offer tax efficiency in retirement.

It's also possible to use both a SIMPLE IRA and a Roth IRA. If you're eligible for both, it can make sense to max out contributions to your Roth IRA first and then use your SIMPLE IRA to save more.

SIMPLE vs. Roth IRA FAQs

What other types of IRA accounts are there?

Beyond SIMPLE IRAs and Roth IRAs, there are several other types of individual retirement accounts—each with its own purpose and tax advantages. Traditional IRAs, SEP IRAs and inherited IRAs are some of the most common alternatives, and they offer different contribution rules, eligibility requirements and withdrawal guidelines.

Your guide to saving for retirement with IRAs

Can I have both a SIMPLE IRA and a Roth IRA?

Yes, you can contribute to both a SIMPLE IRA and a Roth IRA—as long as you meet the eligibility requirements for each.

Your SIMPLE IRA is set up through your employer and follows its own contribution limits. A Roth IRA, meanwhile, is opened individually and has income based eligibility rules. Contributing to both can offer more tax diversification in retirement, with pretax savings in a SIMPLE IRA and tax-free withdrawals from a Roth IRA.

Are Roth IRA contributions tax-deductible?

Roth IRA contributions are not tax-deductible. You contribute after-tax dollars today, and in exchange, your future withdrawals—including earnings—can be tax-free when you meet the qualified distribution rules.

What are the required minimum distributions (RMDs) on SIMPLE and Roth IRAs?

SIMPLE IRAs follow the same RMD rules as traditional IRAs. That means you must begin taking required minimum distributions starting at age 73 (age 75 if you were born in 1960 or later), and continue them each year based on IRS life expectancy tables.

Roth IRAs work differently. When you’re the original account owner, Roth IRAs do not have RMDs during your lifetime—one of their biggest advantages. However, beneficiaries who inherit a Roth IRA may be subject to RMD rules depending on their relationship to the original owner and the timing.

1 Distributions of earnings are tax-free as long as your Roth IRA is at least five years old and one of the following requirements is met: (1) you are at least age 59½; (2) you are disabled; (3) you are purchasing your first home ($10,000 lifetime maximum); or (4) the money is being paid to a beneficiary.
