| Employee Requirement | None. | Must contribute the same percentage for all eligible employees, if you have any. |
| Best For | Anyone wanting a small, flexible tax-advantaged account. | Self-employed people wanting to shelter a large chunk of profit. |

What is Traditional IRA?
A Traditional IRA is an individual retirement account anyone with earned income can open at a brokerage. Contributions may be tax-deductible depending on your income and whether you (or a spouse) have a workplace plan, and the balance grows tax-deferred until withdrawal in retirement, when it's taxed as ordinary income. For 2026 the contribution limit is roughly $7,000 ($8,000 if you're 50 or older) — a modest but useful amount for anyone building retirement savings alongside other accounts.
For the self-employed, a Traditional IRA is simple to open and requires no paperwork beyond the brokerage application, but its low contribution ceiling means it rarely shelters much of a freelancer's or business owner's profit on its own. It works well as a top-up account after maxing a SEP IRA, or as the primary account for someone with modest self-employment income who wants simplicity above all.

What is SEP IRA?
A SEP IRA (Simplified Employee Pension) is designed specifically for self-employed people and small-business owners, and it dramatically outsizes a Traditional IRA's contribution room. For a sole proprietor, the effective contribution is roughly 20% of net self-employment income (after accounting for the self-employment tax deduction); for an employer contributing on behalf of W-2 employees, it's up to 25% of compensation. Either way, the dollar cap is far higher than a Traditional IRA — around $70,000 for 2026 — letting a profitable freelance year shelter a huge amount of income at once.
Setup only takes a simple IRS form (5305-SEP) and most brokerages handle it for free. The catch: if you have employees who meet eligibility rules, you must contribute the same percentage of pay for them as you do for yourself, which can get expensive as a team grows. For solo freelancers and consultants, though, a SEP IRA is usually the single best tax-advantaged retirement tool available.
🔑 Key Differences
- Contribution room: SEP IRA allows roughly 10x more than a Traditional IRA for high-earning self-employed people.
- Eligibility: Traditional IRA is open to anyone with earned income; SEP IRA is aimed at self-employed and business owners.
- Employees: A SEP IRA requires equal percentage contributions for eligible employees; a Traditional IRA has no such rule.
- Deduction mechanics: SEP contributions are a business expense; Traditional IRA deductions depend on income and workplace-plan coverage.
- Setup: Both are simple, but SEP IRA needs a short IRS form to establish.
- Combining accounts: You can fund both in the same year — SEP for the bulk of savings, Traditional (or Roth) IRA for a small top-up.
- Decision driver: How much you want to shelter — modest amounts favor a Traditional IRA's simplicity, larger self-employment profit favors the SEP's ceiling.
When to Use Traditional IRA
- You have modest self-employment income or a regular W-2 job.
- You want the simplest possible account with no employer paperwork.
- You've already maxed a SEP IRA and want extra tax-advantaged room.
- You expect to be in a lower tax bracket in retirement and want the upfront deduction.
When to Use SEP IRA
- You're self-employed with meaningful net profit to shelter.
- You want to contribute far more than the Traditional IRA's ~$7,000 cap.
- You're a solo freelancer or consultant with no eligible employees.
- You want a simple plan to set up without a full 401(k)'s complexity.

💡 Real-World Examples
Example 1: Freelancer, $150,000 Net Profit
A freelance consultant with $150,000 in net self-employment income contributes about 20% — roughly $30,000 — to a SEP IRA, sheltering far more income than the ~$7,000 Traditional IRA cap would allow, and cutting their taxable income substantially.
Example 2: Side-Gig Income, $12,000 Net Profit
Someone with a small side business earning $12,000 net profit can contribute about 20% (~$2,400) to a SEP IRA — but since that's under the $7,000 Traditional IRA limit, a Traditional or Roth IRA may be simpler if they have other earned income to fund it fully.
Example 3: Solo Owner Maxing Both
A consultant nets $120,000 and contributes the SEP IRA maximum for that income level (~$24,000), then also funds a $7,000 Traditional IRA using a spouse's W-2 income, combining both accounts for roughly $31,000 in tax-advantaged retirement savings in one year.
❓ Frequently Asked Questions
Can I contribute to both a Traditional IRA and a SEP IRA?
Yes — they're separate accounts with separate rules, though your Traditional IRA deduction may be limited since a SEP IRA counts as an employer-sponsored plan for that purpose.
How is the SEP IRA contribution limit calculated?
For a sole proprietor, it's roughly 20% of net self-employment income after certain adjustments; for an employer contributing for W-2 staff, it's up to 25% of compensation, capped at a dollar maximum (around $70,000 for 2026).
Do I have to contribute to a SEP IRA every year?
No — contributions are discretionary year to year, which suits variable freelance income. In a lean year, contribute less or nothing; in a strong year, shelter more.
Is there a Roth SEP IRA?
Some plans now allow Roth SEP contributions, but the classic SEP IRA is pre-tax only. Compare with our [retirement calculator](/calculators/retirement-calculator.html) to see which tax treatment benefits you more over time.
What if I have employees?
You must contribute the same percentage of compensation for all eligible employees that you contribute for yourself, which can make a SEP IRA costly once you have staff — a Solo 401(k) or SIMPLE IRA may fit better at that point.
