A single-member LLC (SMLLC) is typically a "disregarded entity" for federal tax purposes, which makes it a flexible vehicle for holding 1031 exchange property. This guide explains how the same-taxpayer rule applies to an SMLLC, when you can sell as an individual and buy through an SMLLC (or vice versa), and the title and California considerations to watch.
General information only — not tax, legal, or financial advice. A 1031 exchange has strict, unforgiving deadlines and significant tax consequences. Work with a CPA and a qualified intermediary (QI) before you act. A REALTOR® cannot serve as your QI. Verify current IRS and California FTB rules with a licensed tax professional.
Why the taxpayer must stay the same
Section 1031 requires that the same taxpayer who sells the relinquished property acquires the replacement property. A change in taxpayer generally breaks the exchange. The question with an LLC is whether the LLC is a separate taxpayer or disregarded.
How a single-member LLC is treated
By default, a domestic single-member LLC is a disregarded entity: the IRS looks through it to its owner. So an individual and their wholly owned SMLLC are treated as the same taxpayer. This gives you flexibility:
- Sell as an individual, buy through your SMLLC.
- Sell through your SMLLC, buy as an individual.
- Sell through one SMLLC, buy through another SMLLC you wholly own.
In each case the taxpayer (you) is unchanged, so the exchange can hold.
Title and documentation pitfalls
- Make sure the SMLLC is truly single-member and disregarded — adding a second member changes everything.
- Keep exchange documents and the qualified intermediary agreement consistent with who is taking title.
- Avoid an unintended election that would treat the LLC as a corporation.
- Lenders may have their own requirements for SMLLC borrowers.
California specifics
- California recognizes disregarded SMLLCs for income tax, but the LLC still has California filing and annual fee/tax obligations.
- If you acquire out-of-state replacement property, the California clawback rules (Form 3840) follow you and apply to the disregarded owner.
- Coordinate franchise tax and registration so the entity is in good standing at closing.
When to use an SMLLC
Investors often use a fresh SMLLC for each replacement property for liability separation while preserving disregarded status. This keeps assets isolated without creating a new taxpayer. Whether that fits your liability and lending needs is a question for your attorney and lender.

Frequently Asked Questions
Can a single-member LLC do a 1031 exchange?
Yes. A disregarded single-member LLC is treated as its owner for tax, so you can sell as an individual and buy through the SMLLC (or vice versa) without breaking the same-taxpayer rule.
Does the name on title have to match?
Not exactly. What matters is that the same taxpayer is involved. Because a disregarded SMLLC is the same taxpayer as its owner, title can shift between them.
What breaks the disregarded status?
Adding a second member, or electing to be taxed as a corporation, changes the entity's tax treatment and can break the exchange. Keep it single-member and disregarded.
Can I use a new SMLLC for the replacement property?
Often yes, for liability separation, as long as you wholly own it and it remains disregarded. Confirm with your attorney and lender.
Does California add requirements?
Yes. The SMLLC has California filing and annual fee obligations, and out-of-state replacements trigger Form 3840 reporting for the owner.
Is this legal advice?
No. This is general educational information. Confirm entity treatment with your CPA and attorney before structuring the exchange.
