If you’re self-employed — freelancer, consultant, gig worker, small business owner — you have access to retirement accounts with higher contribution limits than most W-2 employees get. The catch: nobody sets them up for you. This guide compares every self-employed retirement option, shows you exactly how much you can contribute at different income levels, and tells you which account to open based on your situation.
Quick Answer: Which Account Is Best for You?
| Your Situation | Best Account | Why |
|---|---|---|
| Solo freelancer, any income | Solo 401(k) | Highest contributions, Roth option, loan option |
| Solo freelancer, want simplest setup | SEP IRA | Open and fund in 15 minutes, no annual filings |
| Self-employed with 1-100 employees | SIMPLE IRA | Low admin cost, mandatory employer match |
| High earner ($250K+) wanting massive deductions | Defined benefit plan | Contribute $100K-$300K+/year |
| Side hustle + full-time W-2 job | SEP IRA or Solo 401(k) | Stack on top of employer 401(k) |

How Much Can You Actually Contribute?
Contribution limits depend on your net self-employment income after the self-employment tax deduction.
SEP IRA Contributions by Income
| Net SE Income | SE Tax Deduction | Adjusted Income | SEP Contribution (25%) |
|---|---|---|---|
| $50,000 | -$3,533 | $46,467 | $11,617 |
| $75,000 | -$5,299 | $69,701 | $17,425 |
| $100,000 | -$7,065 | $92,935 | $23,234 |
| $150,000 | -$10,597 | $139,403 | $34,851 |
| $200,000 | -$14,130 | $185,870 | $46,468 |
| $280,000+ | -$19,782 | $260,218 | $65,054 (approaching $70,000 cap) |
Solo 401(k) Contributions by Income
| Net SE Income | Employee Deferral | Employer Contribution (25%) | Total |
|---|---|---|---|
| $50,000 | $23,500 | $11,617 | $35,117 |
| $75,000 | $23,500 | $17,425 | $40,925 |
| $100,000 | $23,500 | $23,234 | $46,734 |
| $150,000 | $23,500 | $34,851 | $58,351 |
| $200,000 | $23,500 | $46,468 | $69,968 |
| $250,000+ | $23,500 | $46,500 (hits $70,000 cap) | $70,000 |
The Solo 401(k) advantage is clear at lower incomes. At $50K net income, a Solo 401(k) lets you contribute $35,117 vs. $11,617 in a SEP IRA — triple the amount — because of the $23,500 employee deferral.
Solo 401(k) with Catch-Up (Age 50+)
| Net SE Income | Employee Deferral | Catch-Up | Employer (25%) | Total |
|---|---|---|---|---|
| $75,000 | $23,500 | $7,500 | $17,425 | $48,425 |
| $100,000 | $23,500 | $7,500 | $23,234 | $54,234 |
| $150,000 | $23,500 | $7,500 | $34,851 | $65,851 |
| $200,000+ | $23,500 | $7,500 | $39,000 (hits $70,000 cap) | $70,000 |
The 2026 catch-up brings the total ceiling to $77,500 for those 50+.
Deep Dive: SEP IRA
Who It’s Best For
- Solo freelancers who want the simplest possible setup
- Self-employed people with employees (SEP requires equal % contributions for all eligible employees)
- Last-minute retirement savers (can open and fund up to tax filing deadline, including extensions)
How It Works
- Open a SEP IRA at any brokerage (Fidelity, Schwab, Vanguard — all free)
- Contribute up to 25% of net self-employment income
- Deduct the full contribution from your taxable income
- All contributions are pre-tax (Traditional) — no Roth option
- No annual IRS filings required
SEP IRA Pros and Cons
| Pros | Cons |
|---|---|
| Open and fund in 15 minutes | No Roth option |
| No annual IRS filings | No employee deferrals (only employer contributions) |
| Can open up to tax deadline | Must contribute same % for all eligible employees |
| No minimum contributions | Lower limits at low incomes vs. Solo 401(k) |
| Free at major brokerages | No loan provision |
Best SEP IRA Providers
| Provider | Account Fee | Fund Options | Minimum | Standout Feature |
|---|---|---|---|---|
| Fidelity | $0 | 10,000+ funds + zero-fee index funds | $0 | FZROX (0.00% ER) available |
| Schwab | $0 | 4,000+ no-load mutual funds | $0 | Integration with Schwab ecosystem |
| Vanguard | $0 ($20 if under $50K) | Vanguard’s full lineup | $0 | Admiral Shares at $3K minimum |
Deep Dive: Solo 401(k)
Who It’s Best For
- Solo freelancers and consultants with no employees (spouse exception)
- Anyone wanting maximum contribution flexibility
- People who want Roth contributions alongside pre-tax
- Those who might need to borrow from retirement funds
How It Works
- Establish the plan by December 31 of the tax year
- Make employee deferrals (up to $23,500 pre-tax or Roth)
- Make employer profit-sharing contributions (up to 25% of net SE income)
- File Form 5500-EZ annually if plan assets exceed $250,000
- Employer contributions can be made up to the tax filing deadline
Solo 401(k) Pros and Cons
| Pros | Cons |
|---|---|
| Highest contribution limits at any income | Must open by Dec 31 (can’t do retroactively) |
| Roth option available | Annual filing at $250K+ plan assets |
| Loan provision (up to $50K or 50% of balance) | Can’t have employees (besides spouse) |
| Employee + employer contribution flexibility | Slightly more complex setup |
| Can combine pre-tax and Roth in one plan | More paperwork than SEP |
Roth Solo 401(k): The Power Move
You can designate your $23,500 employee deferral as Roth, while still making employer contributions pre-tax. This gives you:
| Contribution Type | Amount (at $100K income) | Tax Treatment |
|---|---|---|
| Roth employee deferral | $23,500 | No deduction now, tax-free at withdrawal |
| Pre-tax employer profit-sharing | $23,234 | Deduction now, taxed at withdrawal |
| Total | $46,734 | Mixed tax buckets for retirement flexibility |
This dual approach hedges against future tax rate changes.
Best Solo 401(k) Providers
| Provider | Account Fee | Roth Option | Loan Option | Standout Feature |
|---|---|---|---|---|
| Fidelity | $0 | ✅ | ✅ | Free setup, zero-fee funds, excellent support |
| Schwab | $0 | ✅ | ✅ | Strong mutual fund selection |
| E*TRADE | $0 | ✅ | ✅ | Good mobile app for management |
| Vanguard | $20/year (waived at $50K) | ✅ | ❌ | Lower costs long-term with Admiral Shares |
Recommendation: Fidelity is the best overall choice — $0 fees, Roth option, loan option, and zero expense ratio index funds (FZROX, FZILX).
Deep Dive: SIMPLE IRA
Who It’s Best For
- Self-employed with 1-100 employees
- Small businesses wanting low-cost retirement benefits
- Businesses where the owner earns under $150K (higher earners benefit more from Solo 401(k) or defined benefit)
SIMPLE IRA Contribution Limits (2026)
| Contribution Type | Limit |
|---|---|
| Employee salary deferral | $16,500 |
| Catch-up (age 50+) | $3,500 additional |
| Employer match (mandatory) | 3% dollar-for-dollar match OR 2% non-elective contribution |
| Maximum total | $20,000 (under 50) / $23,500 (50+) |
SIMPLE IRA vs. SEP IRA for Small Business Owners
| Factor | SIMPLE IRA | SEP IRA |
|---|---|---|
| Employee contribution allowed | ✅ Yes ($16,500) | ❌ No (employer only) |
| Employer cost per employee | 3% match or 2% flat | Up to 25% (same % for all) |
| Setup deadline | Oct 1 | Tax filing deadline |
| Max contribution at $100K income | ~$19,500 | ~$23,234 |
| Better for | Owners wanting employees to contribute | High earners wanting maximum deduction |
Deep Dive: Defined Benefit Plan
Who It’s Best For
- High earners ($250K+ net SE income) wanting massive tax deductions
- People 45+ who need to catch up on retirement savings
- Professionals (dentists, doctors, lawyers, consultants) with stable high income
How Much You Can Contribute
Defined benefit plans allow contributions based on your age and desired retirement benefit:
| Age | Approximate Annual Contribution | Tax Savings (32% bracket) |
|---|---|---|
| 40 | $100,000-$150,000 | $32,000-$48,000 |
| 50 | $150,000-$250,000 | $48,000-$80,000 |
| 55 | $200,000-$300,000 | $64,000-$96,000 |
| 60 | $250,000-$350,000+ | $80,000-$112,000 |
Defined Benefit Plan Pros and Cons
| Pros | Cons |
|---|---|
| Largest possible tax deduction | $1,000-$3,000+ annual actuarial fees |
| Can contribute $100K-$350K+/year | Mandatory contributions (must fund every year) |
| Can combine with Solo 401(k) | Complex setup and administration |
| Creditor protection in most states | Need stable, predictable income |
| Accelerates retirement savings for late starters | Must commit for several years |
Combo Strategy: Solo 401(k) + Defined Benefit Plan
For maximum contributions, pair both plans:
| Plan | 2026 Contribution | Tax Savings (35%) |
|---|---|---|
| Solo 401(k) | $70,000 | $24,500 |
| Defined benefit plan | $150,000 (age 50 example) | $52,500 |
| Combined | $220,000 | $77,000 |
This dual approach is most common among high-earning professionals. Requires a third-party administrator (TPA) like Schwab Personal Defined Benefit Plan or a specialized firm.
Side Hustle + W-2 Job: How to Stack Accounts
If you have self-employment income alongside a regular W-2 job, you can contribute to both your employer’s plan and a self-employed plan.
Stacking Rules
| Limit | What It Covers | 2026 Amount |
|---|---|---|
| Employee deferral limit | Shared across ALL 401(k)/403(b)/SIMPLE plans | $23,500 total |
| Employer contribution limit | Per-plan (not shared) | 25% of compensation per plan |
| Total annual additions limit | Per-plan | $70,000 per plan |
Example: $80K W-2 + $40K Side Hustle
| Account | Contribution | Source |
|---|---|---|
| Employer 401(k) | $23,500 (employee deferral, pre-tax) | W-2 income |
| Employer 401(k) match | $4,800 (6% match) | Employer |
| SEP IRA (side hustle) | $9,234 (25% of adjusted SE income) | Self-employment income |
| Total retirement savings | $37,534 |
Important: Since you used your $23,500 employee deferral at your W-2 job, you can only make employer (profit-sharing) contributions to your SEP IRA or Solo 401(k). You cannot contribute another $23,500 as employee deferrals.
Decision Flowchart
-
Do you have employees (besides a spouse)?
- Yes → SEP IRA (simplest) or SIMPLE IRA (employees can contribute)
- No → Continue to #2
-
Is your net SE income under $70,000?
- Yes → Solo 401(k) (employee deferral gives you much higher contribution room)
- No → Continue to #3
-
Do you want a Roth option?
- Yes → Solo 401(k) (only self-employed plan with Roth)
- No → Continue to #4
-
Do you want the simplest possible setup?
- Yes → SEP IRA (open in 15 minutes, no annual filings)
- No → Solo 401(k) (more flexible, loans available)
-
Do you earn $250K+ and want massive tax deductions?
- Yes → Defined benefit plan (possibly combined with Solo 401(k))
Tax Impact Comparison at $100K Net SE Income
| Account | Max Contribution | Taxable Income After | Federal Tax Savings (24%) |
|---|---|---|---|
| No retirement account | $0 | $100,000 | $0 |
| SEP IRA | $23,234 | $76,766 | $5,576 |
| Solo 401(k) | $46,734 | $53,266 | $11,216 |
| Solo 401(k) + DB plan | $146,734 | N/A (need higher income) | N/A |
The Solo 401(k) saves you $11,216 in taxes at $100K income — double the SEP IRA. That’s $11,216 that compounds in your retirement account instead of going to the IRS.
