If you’re self-employed and not yet saving for retirement in a tax-advantaged account, the SEP IRA is one of the most powerful and least complicated places to start. It takes less than 30 minutes to open, requires no ongoing administrative work, and allows contribution limits that dwarf what most employees can put into a workplace 401(k).
This guide walks through exactly what a SEP IRA is, who it’s right for, how much you can contribute in 2026, and the step-by-step process to open one — even if you’ve never opened a retirement account before.

What Is a SEP IRA?
SEP stands for Simplified Employee Pension. Despite the name, it has nothing to do with being an employee — it’s one of the most freelancer-friendly retirement accounts in the tax code.
A SEP IRA works like a traditional IRA in most respects: you contribute pre-tax dollars, the money grows tax-deferred, and you pay income tax when you withdraw funds in retirement (typically after age 59½). What makes it different is the contribution limit, which is dramatically higher than a standard IRA.
In 2026, you can contribute up to 25% of your net self-employment income, with a maximum of $72,000. By comparison, the standard IRA contribution limit is just $7,000 (or $8,000 if you’re 50 or older). The SEP IRA lets freelancers at any income level save aggressively for retirement while reducing their taxable income in the current year.
Who Should Open a SEP IRA?
A SEP IRA is a strong fit if you:
- Are self-employed as a sole proprietor, freelancer, or independent contractor
- Have net self-employment income and want to reduce your tax bill now
- Want a retirement account with minimal setup and no annual filings
- Are the only person in your business (or have no employees, since you’d need to contribute equally for any eligible employees)
- Want to maximize contributions in high-income years and contribute less or nothing in lean years — SEP IRAs have no annual contribution requirement
It’s worth knowing that the Solo 401(k) often allows higher contributions at lower income levels (because it allows an employee elective deferral on top of the employer profit-sharing contribution), while the SEP IRA wins in simplicity. If your net self-employment income is above $100,000, the two are worth comparing. Below that, a Solo 401(k) frequently lets you shelter more.
How Much Can You Actually Contribute in 2026?
The SEP IRA limit is 25% of net self-employment income — not gross revenue. Net self-employment income is your profit after business expenses, reduced by half of your self-employment tax.
Here’s a simplified example:
- Gross freelance revenue: $100,000
- Business expenses: $15,000
- Net profit: $85,000
- Half of self-employment tax (~7.65% of net): ~$6,503
- Net self-employment income for SEP calculation: ~$78,497
- Maximum SEP IRA contribution (25%): ~$19,624
The IRS provides a worksheet in Publication 560 that walks through the exact calculation, and most tax software computes it automatically. The key takeaway: the limit is based on actual business profit, not top-line income.
The absolute ceiling for 2026 is $72,000 regardless of income, meaning very high earners hit the cap before the 25% formula does.
Step-by-Step: How to Open a SEP IRA
Step 1: Choose Where to Open the Account
You can open a SEP IRA at any brokerage or financial institution that offers retirement accounts. For most freelancers, the best options are low-cost brokerages with no account fees, a wide range of investment options, and a simple online setup process.
Strong options to compare:
Fidelity — No account fees, no minimum to open, wide investment selection including index funds and ETFs. One of the most popular choices for self-employed retirement accounts.
Vanguard — Known for low-cost index funds and long-term focus. Excellent for passive investors. Interface is more dated than competitors but the fund costs are among the lowest available.
Charles Schwab — No fees, strong customer service, good mobile app. A solid all-around choice with a seamless online application.
Betterment for Business — A robo-advisor option that automatically invests your contributions in a diversified portfolio based on your risk tolerance and timeline. Good if you don’t want to choose individual investments.
TD Ameritrade (now part of Schwab) — Largely merged with Schwab’s platform but still maintains some separate account structures. Follow current Schwab guidance if starting new.
All of these allow you to open a SEP IRA online in a single session. For most freelancers, Fidelity or Schwab is the practical starting point.
Step 2: Gather What You Need
Opening a SEP IRA requires surprisingly little documentation. Have the following ready:
- Social Security number (for sole proprietors) or EIN if you have one
- Personal identification (driver’s license or passport)
- Bank account and routing number for your initial contribution
- Your estimated net self-employment income for the year (to know how much you can contribute — an exact figure isn’t required to open the account)
You do not need an LLC, an EIN, or any special business registration. A sole proprietor using their Social Security number can open a SEP IRA directly.
Step 3: Complete the IRS Form 5305-SEP (or Let the Brokerage Handle It)
Technically, establishing a SEP IRA requires executing a written agreement — IRS Form 5305-SEP is the standard document for this. In practice, every major brokerage handles this automatically during the account opening process. You won’t fill out a separate IRS form; the brokerage paperwork substitutes for it.
You do not file Form 5305-SEP with the IRS. You keep a copy for your records.
Step 4: Open the Account Online
Visit your chosen brokerage’s website and navigate to “Open an Account” or “Retirement Accounts.” Select SEP IRA from the account type list. Fill in your personal information, agree to the account terms (which include the SEP adoption agreement), and submit.
Most brokerages approve the account instantly or within one business day. You’ll receive an account number and can proceed to fund it.
Step 5: Fund the Account
Connect your bank account (personal or business checking) and initiate a transfer. You can contribute any amount up to your calculated maximum — there’s no requirement to contribute the full amount, and no requirement to contribute at all in a given year.
Critical deadline: SEP IRA contributions for a given tax year can be made up until your tax filing deadline, including extensions. For most freelancers, that means contributions for 2026 can be made as late as October 15, 2027 if you file an extension. This flexibility is one of the SEP IRA’s most valuable features — you can wait until you know your exact net income and tax situation before deciding how much to contribute.
Step 6: Choose Your Investments
Once the account is funded, the money sits as cash until you invest it. This step is where many beginners freeze — but it doesn’t need to be complicated.
For most freelancers who are new to investing, a single target-date fund is the simplest and most defensible starting point. These are funds that automatically shift from growth-oriented investments to more conservative ones as you approach a target retirement year. Find the fund closest to the year you turn 65 and put 100% of your contribution there. Done.
If you want slightly more control, a simple three-fund portfolio — a total US stock market index fund, an international stock index fund, and a bond index fund — is the approach most evidence-based investors recommend. At Fidelity or Schwab, the expense ratios on these funds are typically 0.03–0.10% annually, meaning fees consume almost nothing.
The wrong move is leaving contributions sitting as uninvested cash indefinitely, which earns money-market rates instead of long-term market returns.
Step 7: Record the Contribution for Your Taxes
SEP IRA contributions are deducted on Schedule 1 of your Form 1040 — not on Schedule C. Your tax software will ask whether you made SEP IRA contributions during the year; enter the amount, and it flows to the correct line automatically.
There is no separate IRS filing for a SEP IRA. No Form 5500, no annual reporting requirement. This is one of the primary advantages over a Solo 401(k), which requires Form 5500-EZ once assets exceed $250,000.
Common Beginner Questions
Can I have a SEP IRA and a regular IRA at the same time? Yes. A SEP IRA doesn’t prevent you from also contributing to a traditional or Roth IRA, though your Roth IRA eligibility phases out at higher incomes. You can maintain both simultaneously.
Can I open a SEP IRA if I have a W-2 job in addition to freelance income? Yes. You can have a SEP IRA based on your self-employment income even if you also participate in an employer’s 401(k). The SEP contribution limit is calculated solely on your net self-employment earnings.
What if I have employees? If you hire W-2 employees who meet eligibility criteria (21 or older, worked for you in three of the last five years, earned at least $750), you must contribute the same percentage of compensation to their SEP IRAs as you contribute to your own. This is the main reason many growing freelance businesses switch to a Solo 401(k) instead — the Solo 401(k) is only available to businesses with no employees other than a spouse.
Can I withdraw the money early? Withdrawals before age 59½ are subject to income tax plus a 10% early withdrawal penalty, with limited exceptions. This is standard for pre-tax retirement accounts. The money is intended to stay invested until retirement.
The Bottom Line
A SEP IRA takes under 30 minutes to open, requires zero ongoing administrative work, and offers contribution limits that can shelter tens of thousands of dollars of freelance income from current-year taxes. For a sole proprietor with no employees who wants to start saving for retirement without complexity, it’s one of the best tools available in the tax code — and one of the most underused.
Open the account before the calendar year ends. Decide how much to contribute anytime before your tax filing deadline. Invest in a low-cost index fund. Repeat every year your income allows it.
