WHY IS A SOLO 401K BETTER FOR SMALL BUSINESS THAN TRADITIONAL IRA ?
A Solo 401(k) can be much better than an IRA for the right person, mainly if you’re self‑employed with no full‑time employees (other than a spouse). Here are the key advantages in simple terms:
Much higher contribution limits
Solo 401(k): You contribute as both employee and employer , so your total annual limit can be several times higher than an IRA.
IRA: Has relatively low annual limits.
Result: You can shelter substantially more income from taxes each year with a Solo 401(k).
Dual tax buckets: pre‑tax and Roth
Many Solo 401(k)s let you do:
Pre‑tax (traditional) contributions – reduce your taxable income now.
Roth contributions – no deduction now, but tax‑free withdrawals in retirement.
Traditional IRAs don’t have a Roth option inside the same account, and Roth IRAs have much lower contribution limits.
Result: More tax flexibility and the ability to build a large Roth balance.
Plan loan feature
Solo 401(k): You can usually borrow up to the lesser of $50,000 or 50% of your vested balance.
Use it for business capital, emergencies, or even to pay off high‑interest debt.
You repay the loan with interest back to your own plan .
IRA: Loans are generally not allowed.
Result: Access to liquidity without triggering taxes/penalties (if you follow the rules).
Potentially broader investment options
A self‑directed Solo 401(k) can often invest in:
Real estate, trust deeds, private notes, private equity, precious metals, etc.
Some Solo 401(k)s (like through Imagine IRA) can even include life insurance as an investment, if written through Imagine Financial Group, LLC.
Many IRAs are limited to traditional stocks, bonds, and mutual funds unless they’re self‑directed.
Result: More control and diversification opportunities.
Spousal participation
If your spouse earns income from your business , they can also participate in the Solo 401(k) and make their own employee and employer contributions.
This can effectively double your household’s tax‑advantaged savings.
IRAs are always individual; you don’t get this combined structure tied to the same business.
Bigger current‑year tax savings
Because you can contribute so much more (especially as the “employer”), you can often reduce your taxable income far more than with an IRA alone.
This is especially powerful for higher‑income self‑employed people.
In short:
If you’re self‑employed with no full‑time employees (other than a spouse) and you want to maximize contributions, tax benefits, flexibility, and access to loans, a Solo 401(k) is usually superior to an IRA.
I can outline how much you might be able to put into a Solo 401(k) vs an IRA. Happy to help you run through that next!
