Key Data and Analysis
Retirement account comparison: W-2 employee vs. freelancer FIRE tools
| Account | Max Contribution (2025) | Employee vs. Freelancer | FIRE Use |
|---|---|---|---|
| 401(k) | $23,500 | Employer provides; freelancer uses Solo 401(k) | Primary pre-tax savings |
| Solo 401(k) employer side | 25% of net SE income up to ~$46K | Freelancer only | Major FIRE accelerator |
| IRA (traditional or Roth) | $7,000 | Both | Secondary savings |
| SEP-IRA | 25% of net SE income | Freelancer only | Simpler alternative to Solo 401(k) |
| HSA | $4,300 (individual) | Self-employed w/ HDHP | Triple tax advantage |
🔑The Solo 401(k) Freelancer Advantage
A freelancer earning $90,000 net can contribute up to $23,500 (employee side) + $22,500 (employer side = 25% of $90K) = $46,000 in a Solo 401(k) — far exceeding a W-2 employee’s 401(k) capacity. This is the freelancer’s primary FIRE superpower.
