The Simplified Employee Pension Individual Retirement Arrangement (SEP-IRA) is a great place for self-employed individuals to direct money for retirement. But it's important to learn—and stay within—the legal contribution limits and deadlines.

Basics of SEP-IRAs

SEP plans provide business owners a vehicle for saving for retirement for themselves and their employees. Under a SEP plan, businesses of any size, including self-employed individuals, can establish and contribute money for each employee of the business to a SEP-IRA. The SEP-IRA is a fairly simple retirement account that you can establish and manage with minimal paperwork and no annual filing requirements.

SEP-IRAs give investors the ability to make tax-deductible contributions and grow the earnings from those contributions on a tax-deferred basis—that is, neither the initial contribution nor the gains will be taxed until you withdraw them in retirement. SEP-IRAs also offer funding flexibility from one year to another—a win for a business with fluctuating fortunes. If your business is having a stellar year, you can invest up to the SEP-IRA contribution limits. If it is a tight year, you can choose not to make any contributions that year.

Contributions to a SEP-IRA are legally treated as traditional IRA assets, and as a result, are subject to many of the same rules as traditional IRAs.

SEP-IRA Contribution Limits

One of the most appealing features of SEP-IRAs is the large amount you can put away for retirement. All SEP-IRA contributions are considered employer contributions on behalf of employees. If you decide to establish a SEP-IRA, you can contribute up to the lesser of:

  • 25% of employee compensation
  • $57,000 in 2021

If you're contributing on behalf of other employees of the business, you have to contribute the same percentage of compensation for all employees. In addition, if you're a self-employed individual contributing to your own SEP-IRA, your compensation amounts to your adjusted self-employment income for the year.

The annual limit will be subject to future cost of living adjustments. The high contributions potential of the account may allow you to put away more money for retirement in an SEP-IRA than you could in a traditional IRA. This is because depending on your actual income, the SEP-IRA contribution limits may be greater than the Individual Retirement Account (IRA) IRA limit of $6,000 in 2021 ($7,000 for people aged 50 or older).

Also compare SEP-IRA limits to the 401(k) contribution limit for employees, which is $19,500 ($26,000 for ages 50 or older) in tax year 2021. Unlike IRAs and 401(k)s, SEP-IRAs do not offer any catch-up provisions. But the good news is that the SEP-IRA contribution limits are already high.

Calculating Your Net Adjusted Self-Employment Income

Self-employed individuals will have to use their net adjusted self-employment income as compensation when calculating the SEP-IRA contribution limit of 25% of compensation. Use this special formula to calculate your net adjusted self-employment income:

  1. Determine your gross income.
  2. Subtract business expenses (including your SEP-IRA contributions).
  3. Subtract half of your self-employment tax.

Vanguard provides a useful calculator to help you determine your maximum contributions to a SEP-IRA. However, it is advisable to consult with a professional tax advisor if you have additional questions about how much you can contribute to a SEP-IRA.

Employees can also make tax-deductible traditional IRA contributions to a SEP-IRA if the plan allows for non-SEP contributions. But the ability to deduct those contributions may be limited or eliminated because of your participation in the SEP.

Contribution Deadlines for SEP-IRAs

Like traditional IRAs, SEP-IRAs provide a last-minute tax savings opportunity to reduce your tax bill as a business owner. However, you must adhere to the SEP contribution deadlines to reap those savings at tax time.

If you are self-employed or own a small business, a SEP-IRA must be established by your company’s tax filing deadline (plus any extensions) for the tax year to which the qualifying contribution is made. For example, the tax filing deadline for many entrepreneurs and small business owners for the tax year is generally April 15. Requesting an extension will extend the tax filing deadline, usually until October 15. It is important to remember that requesting a filing extension does not provide an extension on paying the taxes that will eventually be due.

Similar SEP-IRA contribution deadlines apply when depositing funds into a SEP-IRA. SEP-IRA contributions can be made for last year until the tax filing deadline. Filing an extension will generally allow you to delay filing a tax return until October 15. You will still have time to establish a SEP-IRA and make a SEP-IRA contribution until the tax filing deadline. Be sure to notify the IRA custodian to code the contribution for the prior year, if that is your intention.

Keep SEP-IRA Contribution Limits in Context

There are other retirement plans for small businesses and self-employed individuals, such as SIMPLE IRAs, individual 401(k)s, Keoghs, or regular 401(k)s for small businesses. Before establishing an SEP-IRA and contributing your hard-earned money according to these contribution limits and deadlines, it makes sense to compare the various retirement options for small businesses and decide which one is right for your needs.
