The four types of IRAs and what sets them apart
There are four main types of individual retirement accounts: the Traditional IRA, the Roth IRA, the SEP IRA, and the SIMPLE IRA. The first two are available to almost anyone with earned income. The SEP and SIMPLE are designed for self-employed people and small business owners. The core difference between them comes down to when you pay taxes, how much you can contribute each year, and who can open one.
Understanding which type fits your situation means knowing three things: whether you want a tax break now or in retirement, how much you earn and whether you're self-employed, and whether your employer offers a retirement plan. The wrong choice doesn't lock you in forever—you can move money between accounts—but starting with the right one saves paperwork and keeps more money working for you.
Key Takeaways
- Traditional IRAs let you deduct contributions from your taxes now, but you pay income tax on withdrawals in retirement.
- Roth IRAs take after-tax money now, but withdrawals in retirement are tax-free, and you can withdraw contributions anytime without penalty.
- SEP IRAs are for self-employed people and small business owners and allow much larger annual contributions than Traditional or Roth accounts.
- SIMPLE IRAs are for businesses with 100 or fewer employees and require the employer to make matching or non-elective contributions.
Traditional IRA: tax deduction now, taxes later
A Traditional IRA lets you deduct your contribution from your taxable income in the year you make it. If you earn $50,000 and contribute $7,000 to a Traditional IRA, you report only $43,000 as taxable income that year. The money grows tax-free inside the account, and you pay income tax on withdrawals after age 59½.
The catch: if you or your spouse have access to a workplace retirement plan (like a 401(k)), your ability to deduct the full contribution phases out at higher income levels. The income limits change each year. If neither you nor your spouse has a workplace plan, you can deduct the full amount no matter how much you earn.
You must start taking withdrawals at age 73 (as of 2023, this changed from age 72). These are called required minimum distributions, or RMDs. The IRS calculates how much based on your age and account balance. If you don't take the full amount, you owe a penalty on the shortfall.
Roth IRA: no tax break now, tax-free withdrawals later
A Roth IRA works in reverse. You contribute money you've already paid income tax on—no deduction now. The money grows tax-free, and after age 59½, you withdraw it tax-free. You also never have to take required minimum distributions, which means the account can keep growing as long as you live.
The trade-off is that your income determines whether you can contribute the full amount. If your income exceeds a certain threshold, your contribution limit phases out. For 2024, the phase-out begins at $146,000 for single filers and $230,000 for married couples filing jointly. These limits rise each year.
One major advantage: you can withdraw the money you contributed (not the earnings) anytime without penalty or tax, even before age 59½. This makes a Roth useful as an emergency fund that also grows for retirement. If you withdraw earnings early, you owe taxes and a 10% penalty unless you meet an exception.
SEP IRA: for self-employed people and small business owners
A SEP IRA (Simplified Employee Pension) is designed for self-employed people, freelancers, and small business owners. You can contribute up to 25% of your net self-employment income, with a maximum of $69,000 per year (as of 2024). That's far more than the $7,000 limit on Traditional and Roth IRAs.
If you have employees, you must contribute the same percentage of their salary that you contribute for yourself. This makes SEP IRAs less practical if you have many employees, but ideal if you're solo or have just a few people on payroll.
SEP IRAs work like Traditional IRAs: contributions are tax-deductible, money grows tax-free, and you pay income tax on withdrawals. You must start taking required minimum distributions at age 73. Setting one up is straightforward—you fill out a one-page IRS form and open the account with a bank or brokerage.
SIMPLE IRA: for small businesses with employees
A SIMPLE IRA is for businesses with 100 or fewer employees. Unlike a SEP, a SIMPLE requires the employer to make contributions on behalf of workers. The employer can either match employee contributions dollar-for-dollar up to 3% of salary, or make a non-elective contribution of 2% of salary for all may be able to access employees.
Employees can contribute up to $16,000 per year (as of 2024), plus an extra $3,500 if they're age 50 or older. The employer's matching or non-elective contribution goes on top of that. This makes SIMPLE IRAs more expensive for employers than SEP IRAs, but they're simpler to administer and give employees more control over their contributions.
Like Traditional IRAs, SIMPLE IRAs are tax-deductible for contributions, grow tax-free, and require taxes on withdrawals. Required minimum distributions begin at age 73. There's a catch for early withdrawals: if you take money out within two years of opening the account, the penalty is 25% instead of the usual 10%.
Comparing contribution limits and who can open each type
| Account Type | Who Can Open | 2024 Contribution Limit | Tax Treatment |
|---|---|---|---|
| Traditional IRA | Anyone with earned income | $7,000 ($8,500 age 50+) | Deductible now, taxed on withdrawal |
| Roth IRA | Anyone with earned income (subject to income limits) | $7,000 ($8,500 age 50+) | After-tax now, tax-free withdrawal |
| SEP IRA | Self-employed, business owners, freelancers | Up to 25% of net income, max $69,000 | Deductible now, taxed on withdrawal |
| SIMPLE IRA | Businesses with 100 or fewer employees | $16,000 employee + employer match/non-elective | Deductible now, taxed on withdrawal |
How to decide which type is right for you
Start by asking whether you're self-employed or have employees. If you're a W-2 employee with no side income, you choose between Traditional and Roth. If you're self-employed with no employees, a SEP IRA usually makes the most sense because of the higher contribution limit. If you own a business with employees, a SIMPLE IRA is often simpler than a SEP.
Next, think about taxes. Choose Traditional if you want to lower your taxable income this year and expect to be in a lower tax bracket in retirement. Choose Roth if you expect to be in a higher bracket later, or if you want the flexibility of tax-free withdrawals and no required distributions. You can also split the difference: contribute to both a Traditional and a Roth in the same year, as long as your combined contributions don't exceed the annual limit.
Finally, consider your timeline. If you might need the money before retirement, a Roth lets you withdraw contributions penalty-free. If you want the largest possible tax deduction and have self-employment income, a SEP IRA is hard to beat. If you're unsure, start with a Traditional IRA—it's the most flexible, and you can always move money to a different account type later.
Frequently Asked Questions
Can I have both a Traditional IRA and a Roth IRA at the same time?
Yes. Your combined contributions to both accounts cannot exceed the annual limit ($7,000 for 2024, or $8,500 if you're 50 or older), but you can split that money between them however you want. Many people use this strategy to get some tax savings now and some tax-free growth later.
What happens if I contribute too much to an IRA?
If you over-contribute, the IRS charges a 6% excise tax on the excess amount each year until you remove it. You can withdraw the excess and any earnings on it, and you'll owe income tax on the earnings portion. It's worth fixing quickly if it happens.
Can I move money from one IRA type to another?
Yes, through a process called a rollover or conversion. You can move money from a Traditional IRA to a Roth, though you'll owe income tax on the amount converted. You can also move money between Traditional IRAs, or between Roth IRAs, without tax consequences. Check with your bank or brokerage about their process.
Do I need earned income to open an IRA?
Yes, for Traditional and Roth IRAs. You must have income from work—wages, self-employment income, or taxable alimony—to contribute. A SEP or SIMPLE IRA also requires business income. Passive income like dividends or rental income doesn't count.
What if my employer offers a 401(k)—should I still open an IRA?
Many people do both. A 401(k) often has higher contribution limits and may include employer matching. An IRA gives you more control over investments and lower fees. You can contribute to both in the same year, though your Traditional IRA deduction may be limited if your income is high.
