If you are self-employed, a self-directed Solo 401(k) can buy real estate with your retirement money. Done right, the rent and the profit grow inside the plan. Done wrong, you can trigger a prohibited transaction and lose the tax benefits on the whole account.
Here is how it works, and the lines you cannot cross.
Who can use a Solo 401(k)
A Solo 401(k) is for a business owner with no full-time employees other than the owner and a spouse. To buy real estate with it, the plan documents have to allow alternative investments. Many big brokerages offer Solo 401(k) plans that only hold stocks and funds, so you need a provider whose plan is self-directed.
How the purchase works
- The plan buys the property, not you. Title goes in the name of the 401(k) trust.
- The plan pays every expense: taxes, insurance, repairs, and management.
- The plan collects every dollar of income. Rent and sale proceeds go back into the plan account, not your personal account.
The rules you cannot break
The IRS calls these prohibited transactions. The most common ways people get in trouble:
- Personal use. You, your spouse, your parents, and your children cannot live in, vacation at, or rent the property.
- Doing deals with family. The plan cannot buy from or sell to you or those same family members.
- Paying expenses yourself. If you pay the property tax from your personal account, that is a problem. Everything runs through the plan.
- Doing the work yourself. Your own labor on the property, often called sweat equity, can count as a prohibited contribution. Hire it out and pay from the plan.
- Personal guarantees. If the plan borrows money, the loan must be non-recourse. You cannot personally guarantee it.
A real advantage over a self-directed IRA
When a self-directed IRA buys property with a loan, part of the income can be hit with a tax called UDFI, short for unrelated debt-financed income. A Solo 401(k) is generally exempt from that tax on real estate bought with a non-recourse loan. For investors who plan to use leverage, that is a big reason to pick a Solo 401(k) over an IRA.
What it is good for, and what it is not
A Solo 401(k) works well for long-term rentals, notes, and private lending, where the plan just collects income. It works poorly for anything you want to touch personally, like a house you plan to fix up yourself or a place you want to use later.
Contribution limits change every year and depend on what your business earns, so check the current numbers with your CPA or plan provider before you fund the account.
Get the right help
This is an area where a small mistake is expensive. Work with a plan provider that specializes in self-directed plans, and have a CPA or ERISA attorney review the first deal before you close. If you want to talk through how a Solo 401(k) could fit your investing, contact me.
