Freelancer Retirement Planning: Building Wealth Without an Employer Match (2026)

Self-employed people have access to retirement accounts with contribution ceilings well above a typical workplace plan — a SEP IRA, a solo 401(k), a SIMPLE IRA, or an ordinary traditional or Roth IRA alongside any of them. The catch is structural: there is no employer match, so every dollar contributed is a dollar of business revenue diverted, and the decision competes directly with cash buffer and tax set-aside.

The Four Options Compared

All dollar limits below are indexed annually by the IRS, so check the current year figure before contributing. The mechanisms, however, are stable and are what determine which plan suits which income level.

Why the SEP Percentage Is 20%, Not 25%

The 25% figure applies to an employee salary. For a self-employed person, compensation is net earnings after subtracting both half of self-employment tax and the contribution itself, and solving that circular definition produces an effective 20% of adjusted net earnings.

Net self-employment income: $120,000
SE tax base: $120,000 x 92.35% = $110,820
Self-employment tax at 15.3%: $16,955
Deductible half: $8,478
Adjusted net earnings: $120,000 - $8,478 = $111,522
SEP IRA maximum: $111,522 x 20% = $22,304
Solo 401(k): the same $22,304 employer share plus an employee deferral
The deferral is what makes a solo 401(k) larger at this income level

At $120,000 of net income, the solo 401(k) advantage is the entire employee deferral — a difference of well over $20,000 of tax-deferred space in a typical year. Below roughly $60,000 of net income the deferral does most of the work in either plan, and above about $300,000 both converge on the same overall cap.

Choosing and Setting Up

1. Estimate net self-employment income for the year, then compute the 20% adjusted-net-earnings figure to see the employer-side capacity.
2. If that figure alone hits your savings target, take the SEP IRA for its near-zero administration.
3. If you want to contribute more than 20% of net earnings, open a solo 401(k) — the employee deferral is the only route to it.
4. Check whether Roth treatment matters to you; solo 401(k) plans commonly allow Roth deferrals while a SEP is traditional by default.
5. Watch the establishment deadlines: a SEP can generally be opened and funded up to the tax filing deadline including extensions, while a 401(k) has stricter timing.
6. Revisit annually, because indexed limits and a variable income change the optimal plan more often than the plan itself needs changing.

Sequencing Retirement Against Everything Else

Retirement contributions compete with the tax set-aside and the cash buffer, and losing that competition is expensive: a missed quarterly payment triggers IRS underpayment penalties, while a missed contribution costs only the compounding. Fund the tax set-aside first, then a cash buffer of three to six months of expenses, then retirement to the level your revenue supports. Remember that self-employment tax also buys Social Security credits, which the SSA converts into a benefit based on your highest 35 years of indexed earnings — that benefit is a real part of the retirement picture, not a substitute for saving.

Contribute quarterly rather than in a December lump sum. It smooths cash flow and removes the temptation to skip the year entirely after a weak quarter.
