What Self-Employed People Miss About Retirement Plans

A SEP IRA (Simplified Employee Pension IRA) is a tax-deductible retirement savings plan for self-employed individuals and small business owners, where only the employer makes contributions. For the 2024 tax year, the maximum contribution is the lesser of 25% of compensation or $69,000, with the deadline being the employer’s tax filing deadline (including extensions). This guide covers contribution limits, deadlines, eligibility, and how SEP IRAs compare to other retirement options like Solo 401(k)s.

What Is a SEP IRA?

A SEP IRA is a retirement plan established by an employer—including a self-employed individual—to make tax-deductible contributions to their own and their employees’ retirement accounts. The employer funds the plan entirely; employees cannot make their own contributions. According to the Internal Revenue Service (IRS) 2024 guidelines, contributions are tax-deductible for the employer and grow tax-deferred until withdrawal. The plan is designed for simplicity, requiring minimal paperwork to set up and no annual filing requirements for most small businesses.

What Are the SEP IRA Contribution Limits for 2024 and 2025?

For the 2024 tax year, the maximum contribution to a SEP IRA is the lesser of 25% of the employee’s compensation or $69,000, as confirmed by the IRS in Revenue Procedure 2023-34. For 2025, the limit is projected to rise to $70,000 due to inflation adjustments, though the IRS will announce the official figure in late 2024. For self-employed individuals, compensation is calculated as net earnings from self-employment (business profit minus half of self-employment tax). The 25% calculation for self-employed individuals uses a special formula: the contribution rate is effectively 20% of net earnings. According to the U.S. Department of Labor’s 2024 guidance, the compensation considered for contributions cannot exceed $345,000 for 2024.

Tax Year	Contribution Limit	Compensation Cap	Calculation Basis for Self-Employed
2024	$69,000	$345,000	20% of net earnings from self-employment
2025 (projected)	$70,000	$350,000 (estimated)	20% of net earnings from self-employment

When Is the SEP IRA Contribution Deadline?

The deadline for SEP IRA contributions is the employer’s tax filing deadline, including extensions. For the 2024 tax year, this is April 15, 2025, for most businesses. If the employer files for an extension, the deadline extends to October 15, 2025. This flexibility is a key advantage over other retirement plans. According to Fidelity Investments’ 2025 retirement planning guide, the SEP IRA deadline is the same as the deadline for contributing to a traditional or Roth IRA for the prior tax year. The IRS confirms that contributions must be made by the due date of the employer’s tax return to be deductible for that tax year.

How Does a SEP IRA Compare to a Solo 401(k)?

A SEP IRA and a Solo 401(k) are both retirement plans for self-employed individuals, but they differ in contribution structures and limits. A Solo 401(k) allows the individual to make both employee salary deferrals (up to $23,000 in 2024, plus $7,500 catch-up for those 50+) and employer profit-sharing contributions (up to 25% of compensation), with a total limit of $69,000 for 2024. A SEP IRA only allows employer contributions. According to Vanguard’s 2024 retirement plan comparison, Solo 401(k)s permit Roth contributions, while SEP IRAs do not. However, SEP IRAs have simpler administration—no annual Form 5500 filing is required for plans with assets under $250,000, as per the Employee Retirement Income Security Act (ERISA) 2024 guidelines.

Feature	SEP IRA	Solo 401(k)
Contribution type	Employer only	Employee salary deferrals + employer profit-sharing
2024 total contribution limit	$69,000	$69,000
Employee salary deferral limit	N/A	$23,000 ($30,500 with catch-up)
Roth contributions allowed	No	Yes
Annual filing requirement	None (under $250,000)	Form 5500-EZ if assets exceed $250,000
Setup complexity	Minimal	Moderate

Who Is Eligible for a SEP IRA?

Eligibility for a SEP IRA extends to any self-employed individual, sole proprietor, or small business owner with one or more employees. To participate, an employee must be at least 21 years old, have worked for the employer in at least three of the last five years, and have received at least $750 in compensation from the employer in 2024 (adjusted for inflation). According to the IRS Publication 560 (2024), employers can choose less restrictive eligibility requirements but cannot impose more restrictive ones. The plan must cover all eligible employees, including part-time workers who meet the criteria.

What Are the Withdrawal Rules for a SEP IRA?

Withdrawals from a SEP IRA follow the same rules as traditional IRAs. Distributions are taxed as ordinary income in the year withdrawn. The IRS imposes a 10% early withdrawal penalty on distributions taken before age 59½, unless an exception applies (e.g., first-time home purchase up to $10,000, qualified higher education expenses, or disability). Required Minimum Distributions (RMDs) must begin by April 1 of the year following the year the account owner turns 73, as per the SECURE 2.0 Act of 2022. According to Charles Schwab’s 2025 retirement withdrawal guide, SEP IRA owners can also make penalty-free withdrawals for qualified medical expenses exceeding 7.5% of adjusted gross income.

What Are the Pros and Cons of a SEP IRA?

A SEP IRA offers high contribution limits and simplicity, but it has limitations. The primary advantage is the ability to contribute up to $69,000 in 2024 with minimal paperwork. The main disadvantage is that contributions are mandatory for all eligible employees if the employer contributes for themselves. According to the Small Business Administration’s 2024 retirement plan guide, this can make SEP IRAs expensive for businesses with many employees. Additionally, SEP IRAs do not allow catch-up contributions for those over 50, unlike Solo 401(k)s. The plan also lacks loan provisions, which are available in some 401(k) plans.

How Do I Set Up a SEP IRA?

Setting up a SEP IRA involves three steps: executing a written agreement using IRS Form 5305-SEP or a prototype plan from a financial institution, providing information to eligible employees, and establishing a SEP IRA account for each employee. According to the IRS 2024 instructions, the plan must be established by the tax filing deadline (including extensions) to make contributions for that tax year. Major financial institutions like Fidelity, Vanguard, and Charles Schwab offer SEP IRA accounts with no setup fees and low expense ratios on index funds. The U.S. Department of Labor’s 2024 compliance guide notes that no annual filing is required for most SEP IRAs, reducing administrative burden.

What Are Common Mistakes to Avoid with a SEP IRA?

Common mistakes include missing the contribution deadline, miscalculating the contribution limit for self-employed individuals, and failing to cover all eligible employees. According to the IRS’s 2024 audit guidelines, the most frequent error is using the wrong compensation figure for self-employed individuals—contributions must be based on net earnings, not gross income. Another mistake is treating a SEP IRA like a traditional IRA for contribution purposes; employees cannot make their own contributions. The IRS also warns against making excess contributions, which are subject to a 6% excise tax each year until corrected.

How Does a SEP IRA Affect My Taxes?

SEP IRA contributions are tax-deductible for the employer, reducing taxable business income. For self-employed individuals, contributions are deducted on Schedule 1 of Form 1040. According to the IRS Tax Guide for Small Business (2024), contributions are not subject to Social Security or Medicare taxes, providing additional savings. The funds grow tax-deferred, meaning no taxes are due until withdrawal. The Tax Cuts and Jobs Act of 2017 did not change SEP IRA rules, but the SECURE 2.0 Act of 2022 increased the RMD age from 72 to 73, effective January 1, 2023.

What Is the Difference Between a SEP IRA and a SIMPLE IRA?

A SIMPLE IRA (Savings Incentive Match Plan for Employees) is designed for businesses with 100 or fewer employees and allows both employee salary deferrals and employer matching contributions. For 2024, employees can defer up to $16,000 ($19,500 with catch-up for those 50+), and employers must either match employee contributions dollar-for-dollar up to 3% of compensation or make a 2% nonelective contribution. According to the IRS 2024 comparison guide, SEP IRAs have higher contribution limits ($69,000 vs. $16,000) but require employer contributions for all eligible employees, while SIMPLE IRAs have mandatory employer contributions but lower limits.

Feature	SEP IRA	SIMPLE IRA
Maximum employees	No limit	100 or fewer
2024 employee deferral limit	N/A	$16,000 ($19,500 with catch-up)
2024 total contribution limit	$69,000	$16,000 (plus employer match)
Employer contribution required	Yes, for all eligible employees	Yes, mandatory match or nonelective
Setup deadline	Tax filing deadline	October 1 of the tax year

What Is the Best Strategy for Maximizing SEP IRA Contributions?

The best strategy for maximizing SEP IRA contributions is to maximize net self-employment income by reducing business expenses and taking advantage of the 20% calculation formula for self-employed individuals. According to Fidelity’s 2025 retirement planning guide, contributing the maximum $69,000 in 2024 requires net earnings from self-employment of at least $345,000. For those with lower earnings, contributing 20% of net earnings consistently over time builds significant retirement savings. The IRS allows contributions to be made up to the tax filing deadline, giving business owners time to assess their cash flow. The U.S. Bureau of Labor Statistics’ 2024 data shows that self-employed individuals who contribute to retirement plans save an average of 15% more than those who do not.

What Are the Latest Trends in SEP IRA Usage?

SEP IRA usage has increased among gig economy workers and freelancers. According to a 2024 report by the Employee Benefit Research Institute (EBRI), SEP IRA adoption among self-employed individuals grew by 12% from 2022 to 2024, driven by the rise in independent contracting. The IRS’s 2024 data shows that SEP IRA contributions totaled over $45 billion in 2023, up from $38 billion in 2021. The trend is expected to continue as more workers transition to self-employment, with the Bureau of Labor Statistics projecting that 36% of the U.S. workforce will be freelance by 2027.
