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

  1. Open a SEP IRA at any brokerage (Fidelity, Schwab, Vanguard — all free)
  2. Contribute up to 25% of net self-employment income
  3. Deduct the full contribution from your taxable income
  4. All contributions are pre-tax (Traditional) — no Roth option
  5. 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

  1. Establish the plan by December 31 of the tax year
  2. Make employee deferrals (up to $23,500 pre-tax or Roth)
  3. Make employer profit-sharing contributions (up to 25% of net SE income)
  4. File Form 5500-EZ annually if plan assets exceed $250,000
  5. 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

  1. Do you have employees (besides a spouse)?

    • Yes → SEP IRA (simplest) or SIMPLE IRA (employees can contribute)
    • No → Continue to #2
  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
  3. Do you want a Roth option?

    • Yes → Solo 401(k) (only self-employed plan with Roth)
    • No → Continue to #4
  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)
  5. 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.
