💼 What Is a SEP IRA?
A SEP IRA, or Simplified Employee Pension Individual Retirement Account, is a type of retirement savings plan designed for self-employed individuals and small business owners. It allows employers to contribute to traditional IRAs set up for their employees—and to their own accounts if they’re self-employed.
The primary goal of a SEP IRA is to make retirement saving easier for people who work for themselves or operate small businesses. Unlike more complex retirement plans like 401(k)s, a SEP IRA is known for its simplicity, high contribution limits, and tax advantages.
Key Characteristics:
- Easy to set up and maintain
- Employer-funded only (employees can’t contribute)
- Contributions are tax-deductible for the business
- Grows tax-deferred until withdrawal
- Flexible annual contribution amounts
These features make it an attractive option for anyone looking to reduce their taxable income while building long-term savings.
👥 Who Is Eligible to Open a SEP IRA?
The SEP IRA is available to any business owner, including:
- Sole proprietors
- Partnerships
- LLCs and S-Corps
- Freelancers and gig workers
If you earn self-employment income—even from a side hustle—you may qualify.
Employee Eligibility:
If you have employees, the IRS requires you to offer the plan to all who:
- Are at least 21 years old
- Have worked for you in 3 of the last 5 years
- Earned at least $750 in the current year (2025 threshold)
This rule ensures fairness but also means that employers must contribute equally for all eligible employees. That can impact your decision if you’re considering hiring staff.
🧮 How SEP IRA Contributions Work
Unlike other retirement accounts where employees contribute a portion of their paycheck, only the employer makes contributions to a SEP IRA.
For Sole Proprietors:
If you’re self-employed without employees, you contribute to your own SEP IRA as the “employer.”
Contribution Limits:
For 2025, you can contribute up to:
- 25% of compensation, or
- $69,000, whichever is less
Keep in mind, the compensation used to calculate contributions is capped at $345,000 for 2025.
This high contribution limit makes the SEP IRA significantly more powerful than a Traditional or Roth IRA, which has a $7,000 limit in 2025 ($8,000 if over 50).
🧾 Tax Advantages of a SEP IRA
The tax treatment of a SEP IRA is one of its strongest benefits.
For Employers:
- Contributions are tax-deductible as a business expense
- Reduces the company’s taxable income
- Helps both the business and the individual save on taxes
For Individuals:
- Investments grow tax-deferred
- No taxes are owed until withdrawal
- Reduces your current income tax bill
For sole proprietors or freelancers, this can result in substantial savings, especially in high-income years.
📋 Rules for Withdrawals
Because the SEP IRA is technically a Traditional IRA, the same rules apply when withdrawing money.
- Withdrawals before age 59½ are subject to income tax + 10% penalty
- Required Minimum Distributions (RMDs) start at age 73 (as of 2025 law)
There’s no Roth version of a SEP IRA. All funds are taxed when withdrawn. For those seeking tax-free retirement income, this may be a downside.
🏗️ SEP IRA vs Other Retirement Plans
Here’s how the SEP IRA compares to other options:
| Feature | SEP IRA | Solo 401(k) | Traditional IRA | Roth IRA |
|---|---|---|---|---|
| Max Contribution | $69,000 | $69,000 + catch-up | $7,000 | $7,000 |
| Employee Contribution | No | Yes | Yes | Yes |
| Employer Contribution | Yes | Yes | No | No |
| Roth Option | No | Yes | No | Yes |
| RMDs Required? | Yes | Yes | Yes | Yes |
Summary:
- SEP IRA is simpler and ideal for small teams or solo entrepreneurs
- Solo 401(k)s offer more flexibility but are more complex to manage
- IRAs (Traditional or Roth) have lower limits but suit lower-income earners
🛠️ How to Set Up a SEP IRA
Starting a SEP IRA is easy. Most major brokerages—like Fidelity, Vanguard, and Schwab—offer them.
Steps:
- Choose a provider (based on fees, platform, tools)
- Fill out IRS Form 5305-SEP or use your provider’s version
- Open an account and designate it as a SEP IRA
- Decide your annual contribution amount
- Fund the account before the tax filing deadline (including extensions)
It’s that simple. No annual filings or IRS reporting is required, unlike with 401(k)s.
🤔 When Should You Use a SEP IRA?
You should consider opening a SEP IRA if:
- You’re self-employed and want to maximize retirement savings
- You earn a high income and need tax deductions
- You want a simple setup without administrative burden
- You don’t plan to hire employees soon
If you already have employees—or plan to hire—you’ll need to consider whether you’re comfortable contributing the same percentage to their accounts as yours. That’s the biggest limitation of a SEP IRA for growing businesses.
📊 Contribution Flexibility and Planning Advantages
One of the greatest benefits of a SEP IRA is the flexibility in contributions. Unlike 401(k) plans, SEP IRAs do not require fixed annual contributions. This is especially valuable for small business owners and freelancers whose income varies year to year.
In strong income years, you can contribute the maximum allowed. In leaner periods, you can contribute less—or even nothing at all—without penalties or administrative complexity. This feature helps align your retirement planning with your cash flow and business cycles.
It also means you’re not locked into contributing when finances are tight, which offers critical breathing room for entrepreneurs navigating uncertainty.
⏳ Deadline Flexibility
Another often-overlooked feature is that you can contribute to your SEP IRA until your tax filing deadline, including extensions. This allows you to retroactively plan your contributions depending on your final income for the year.
For example:
- Let’s say you’re filing your 2025 taxes and realize you earned more than expected.
- You have until April 15, 2026—or October 15 with an extension—to make a contribution that reduces your 2025 taxable income.
This timing flexibility gives you greater control over your tax strategy and more time to make informed decisions.
📈 Investment Options Inside a SEP IRA
Once funds are contributed, how you invest them matters.
Most SEP IRAs allow a broad range of investment options, depending on your provider:
- Individual stocks
- Bonds and CDs
- Mutual funds and ETFs
- Target-date retirement funds
- Index funds
You can build a diversified portfolio within your SEP IRA based on your risk tolerance, time horizon, and investment goals. Unlike employer-sponsored 401(k)s that may restrict you to a small list of fund options, SEP IRAs—especially those held at brokerages like Fidelity or Vanguard—allow more freedom and customization.
📉 What Happens If You Hire Employees?
Here’s where things can get tricky.
If you currently don’t have employees, a SEP IRA is simple. But once you hire, IRS rules kick in. You must contribute the same percentage of compensation for all eligible employees as you do for yourself.
So if you contribute 20% of your own compensation to your SEP IRA, you must also contribute 20% for each qualifying employee—even if you only hired them recently.
Example:
- You earn $120,000 → contribute 20% = $24,000
- Your new employee earns $40,000 → you must contribute $8,000 to their SEP IRA
This can get expensive quickly, especially for growing businesses. If you plan to scale and hire, a Solo 401(k) may be a better fit long term.
⚖️ SEP IRA vs SIMPLE IRA
Many small businesses also consider a SIMPLE IRA. How does it compare?
| Feature | SEP IRA | SIMPLE IRA |
|---|---|---|
| Who Contributes | Employer only | Employer + Employee |
| Contribution Limit | $69,000 | $16,000 |
| Mandatory Match | No | Yes (3% match or 2% nonelective) |
| Admin Complexity | Low | Low |
| Best For | Solopreneurs or micro-teams | Employers with 10 or fewer employees |
If you want a higher contribution ceiling, SEP is the better choice. If you want employees to contribute to their own retirement without your full financial burden, SIMPLE may suit better.
📑 Paperwork and Administration
Business owners often fear the paperwork and legal burden of retirement plans. Fortunately, SEP IRAs keep it very simple.
No Annual Filing
There’s no annual IRS reporting required. You only need to:
- Fill out Form 5305-SEP once (or your provider’s version)
- Retain records of contributions
- Notify eligible employees annually
This makes it much easier to manage than a Solo 401(k), which requires Form 5500 filings once assets reach $250,000.
🧮 How to Calculate Contributions
Calculating your SEP IRA contribution isn’t as simple as taking 25% of net income. Due to IRS rules on self-employment taxes, the effective contribution limit is closer to 20% of your net self-employment income.
Example:
- Net profit: $100,000
- Subtract 50% of self-employment tax (~$7,065)
- Apply 20% to result → $100,000 – $7,065 = $92,935 x 20% = $18,587
The IRS provides Publication 560 and various worksheets to assist with the calculation, but most tax software or CPAs can handle it for you.
🧠 SEP IRA for Side Hustlers
Even if you already contribute to a 401(k) through your full-time job, you can also open a SEP IRA for your self-employment income.
Here’s how it works:
- Contribution limits are separate from 401(k) employee contributions
- However, employer-side contributions are aggregated across plans
- SEP IRA limits are based only on your self-employed income, not W-2 wages
This can be a fantastic strategy for freelancers, creators, or consultants earning extra money on the side who want to shelter more income from taxes.
❌ Drawbacks of SEP IRAs
While SEP IRAs offer many benefits, they’re not perfect for everyone.
Disadvantages:
- No Roth option: All contributions are pre-tax; no tax-free withdrawals in retirement
- Equal contributions for employees can become costly
- No catch-up contributions for those over 50
- Employer-funded only: Employees can’t add their own money
If you’re looking for tax-free growth or more control for employees, other options might be more appropriate.
💬 Real-World Example: Freelancer vs Business Owner
Let’s look at how two different professionals might benefit from a SEP IRA:
Emily, Freelancer:
- Earns $80,000/year as a writer
- Has no employees
- Contributes 20% of income → $16,000
- Uses funds to buy low-cost ETFs
- Enjoys tax deduction + compound growth
Kevin, Business Owner:
- Earns $200,000
- Has 2 employees earning $50,000 each
- Must contribute $40,000 total if he contributes 20%
- May consider a 401(k) instead due to cost of employee contributions
As you can see, SEP IRAs are excellent for solopreneurs but may lose efficiency as your business grows.
📘 How to Open a SEP IRA Step by Step
Opening a SEP IRA is surprisingly simple. Here’s how to get started:
1. ✅ Choose a Provider
Most major brokerages offer SEP IRAs:
- Fidelity: Great for self-directed investors
- Vanguard: Excellent for index fund simplicity
- Charles Schwab: Strong all-in-one platform
- E*TRADE, TD Ameritrade, and others also provide robust options
Choose a provider based on:
- Investment options
- Platform usability
- Account fees (most are $0)
- Customer support
2. 📝 Complete Form 5305-SEP
This IRS document is what officially creates your SEP plan. If you’re using a provider, they likely fill this out digitally for you. No need to file it with the IRS—just keep it for your records.
3. 📩 Inform Employees (If Any)
If you have eligible employees, you’re legally required to:
- Notify them in writing of their eligibility
- Provide them with a copy of Form 5305-SEP or a similar plan document
- Make equal percentage contributions for them annually
4. 💳 Fund the SEP IRA
You can fund the account through a direct transfer from your business or personal checking account. Most providers make this process seamless online.
5. 📈 Start Investing
Your SEP IRA is just an empty shell until you allocate the funds. You can:
- Pick a target-date fund for a set-it-and-forget-it approach
- Choose low-cost ETFs or index funds
- Build a custom portfolio
Remember: All gains inside your SEP IRA are tax-deferred, meaning you don’t pay taxes until retirement withdrawals.
🧾 Tax Filing and Deductions
SEP Contributions Are Deductible
You can deduct your SEP IRA contributions as a business expense, which reduces your taxable income. If you’re self-employed, you’ll claim this on Schedule C or Schedule 1 of Form 1040.
This deduction is above the line, so you benefit whether or not you itemize.
Reporting for Employees
If you contribute for employees, those contributions are not included in their income and are not subject to Social Security or Medicare taxes. However, you must report them correctly on their W-2 under Box 12 with code “SEP.”
🧠 Best Practices for SEP IRA Success
To make the most of your SEP IRA:
📅 Set a Reminder for Tax Deadlines
Use your SEP IRA strategically by waiting until after you’ve calculated annual profits to contribute—especially if your income fluctuates.
💡 Automate Investments
Just because contributions are flexible doesn’t mean they should be forgotten. Set up automated investments within the account so money doesn’t sit in cash.
📚 Rebalance Annually
Once a year, revisit your asset allocation. As your portfolio grows, your original strategy may drift off target.
🔐 Protect Your Passwords
SEP IRAs are long-term accounts, so use strong, unique passwords and enable two-factor authentication with your provider.
🔄 What Happens If You Convert to a Roth IRA?
Unfortunately, you cannot directly contribute to a Roth account from a SEP IRA. But you can do a Roth conversion.
Here’s how:
- Open a Roth IRA account
- Transfer funds from your SEP IRA to the Roth IRA
- Pay taxes on the converted amount at your current income tax rate
This strategy is useful for those who:
- Are currently in a low tax bracket
- Want to diversify into tax-free income in retirement
- Have room to convert gradually over several years
Be careful: The converted amount increases your taxable income for the year. You may also want to coordinate with a tax advisor if considering a large conversion.
❓ SEP IRA FAQs
Can I have both a 401(k) and a SEP IRA?
Yes, but total contributions across plans are subject to IRS limits. The SEP is considered an employer contribution.
Is there a Roth SEP IRA?
No. SEP IRAs only allow pre-tax contributions. For Roth-style investing, consider a Roth IRA or Solo Roth 401(k).
Can employees contribute?
No. Only the employer contributes in a SEP IRA.
Is it good for side hustlers?
Absolutely. SEP IRAs are ideal for freelancers, consultants, and solopreneurs who want to lower taxable income and invest long term.
✅ Conclusions
A SEP IRA is one of the most powerful yet underutilized retirement tools available to self-employed individuals and small business owners in the U.S.
With high contribution limits, simple setup, and tax-deductible benefits, it’s a no-brainer for freelancers, contractors, and solopreneurs with variable income.
However, as your business scales and you hire employees, you must consider the implications of equal percentage contributions. For those with teams or those wanting a Roth option, a Solo 401(k) or SIMPLE IRA might offer more flexibility.
But for pure simplicity, tax efficiency, and savings power, the SEP IRA shines.
Whether you’re earning $20K or $200K on the side, this account can help you retire richer.
