To transfer LLC ownership to a spouse, you sign an Assignment of Membership Interest, amend the operating agreement to reflect the new ownership, and update your state’s LLC filing. For couples where both spouses are U.S. citizens, federal law allows unlimited gift transfers between spouses with no gift tax owed and usually no gift tax return to file. The bigger consequence is often federal tax classification: adding your spouse as a second member converts a single-member LLC from a disregarded entity into a partnership, with new filing obligations that start the year the transfer takes effect.
Start With the Operating Agreement
Every transfer begins there. The operating agreement controls who can receive a membership interest, what approvals are required, and whether the transfer triggers restrictions such as a right of first refusal for other members. Some agreements permit transfers to immediate family without member approval; don’t assume yours does without reading the language.
If you’re the sole member, consent is not an issue, but the agreement may still require written notice or a formal valuation. If the agreement is silent on spousal transfers, amend it before you proceed. An amendment usually takes a written resolution signed by all current members and should explicitly authorize the transfer and describe the new ownership structure.
If the LLC never adopted an operating agreement at all, your state’s default LLC statute governs. Most states allow free assignment of economic rights but do not automatically grant the recipient full membership status. That distinction is one of the most commonly overlooked steps in this process, and it drives what the assignment document has to accomplish.
Executing the Assignment of Membership Interest
The document that actually transfers ownership is the Assignment of Membership Interest. It’s a standalone legal instrument, separate from any state filing, and it serves as the definitive proof of the transaction. Every subsequent tax and administrative step depends on it.
The assignment should state:
- The exact percentage of your membership interest being conveyed, whether that’s 50%, 100%, or another share.
- Whether the transfer is a gift or a sale for a stated purchase price.
- The effective date, which determines when tax obligations shift.
- Signatures of both the transferring member and the receiving spouse.
If the transfer is a gift, say so in the document and state that the interest is conveyed without monetary consideration. If it’s a sale, spell out the price and payment terms. This distinction directly affects your tax reporting, so don’t leave it ambiguous.
Assignee Rights Versus Full Membership
In most states, assigning a membership interest transfers only economic rights: your spouse’s share of profits, losses, and distributions. It does not automatically grant voting power, management authority, or other governance rights. Without further steps, your spouse becomes an “assignee” rather than a full “member.” Admission to full membership requires either express authorization in the operating agreement or unanimous member consent.
For a single-member LLC where you’re transferring your entire interest, this is less of a practical problem, but the amended operating agreement still needs to formally reflect your spouse as a member with full rights. In a multi-member LLC, the other members may need to vote on admitting your spouse as a full member. Handle this in the paperwork from the start; an assignee with no management rights is in a very different position than a voting member.
Updating State Records
Once the assignment is signed and the operating agreement amended, update the LLC’s public record with your state’s filing office, usually the Secretary of State. Most states require an amendment to the Articles of Organization or Certificate of Formation when membership changes. Filing fees generally fall in the $25 to $100 range, and most states accept electronic submissions.
File promptly. The state recognizes only the members shown in its records, so any lag creates a gap between actual and recorded ownership. In the LLC’s own files, update the Member Register to reflect the new percentages and keep the signed assignment alongside the amended operating agreement as evidence of a clean chain of ownership.
Federal Gift Tax on a Spousal Transfer
If you’re gifting the interest rather than selling it, the IRS treats the transfer as a gift valued at fair market value on the date of conveyance. In most other contexts, that would require filing Form 709.
The Marital Deduction Wipes Out the Tax
Section 2523 of the Internal Revenue Code allows a deduction equal to the full value of any property gifted to a U.S. citizen spouse, reducing the taxable gift to zero regardless of amount.1Office of the Law Revision Counsel. 26 USC 2523 – Gift to Spouse Gift an LLC interest worth $5 million, and the gift tax owed is nothing.
You typically don’t need to file a gift tax return either. The IRS instructions for Form 709 state that no return is required for gifts to a U.S. citizen spouse, aside from narrow exceptions involving certain “terminable interests” or a qualified terminable interest property (QTIP) election.2Internal Revenue Service. Instructions for Form 709 (2025) A straightforward gift of an LLC membership interest does not fall into those exceptions.
If Your Spouse Is Not a U.S. Citizen
The marital deduction does not apply when the recipient spouse is not a U.S. citizen.1Office of the Law Revision Counsel. 26 USC 2523 – Gift to Spouse In its place is a higher annual exclusion, $190,000 for 2025 and indexed for inflation, for gifts to a non-citizen spouse that would otherwise qualify for the marital deduction.3eCFR. 26 CFR 25.2523(i)-1 – Disallowance of Marital Deduction When Spouse Is Not a United States Citizen If your LLC interest exceeds that amount, file Form 709 and the excess counts against your lifetime gift and estate tax exemption, which stands at $15,000,000 for 2026.4Internal Revenue Service.

Your Spouse’s Tax Basis After the Gift
A gifted interest carries over your original basis. If you invested $50,000 and the interest is now worth $200,000, your spouse’s basis stays at $50,000, and they would owe capital gains tax on $150,000 if they later sold at that value.5Office of the Law Revision Counsel. 26 USC 1015 – Basis of Property Acquired by Gifts and Transfers in Trust Selling to your spouse at fair market value gives them a basis equal to the purchase price, which can produce a better result on a future sale but creates a taxable event for you now.
The Transfer Changes Your LLC’s Tax Classification
This is where the real complexity lives. A single-member LLC is a disregarded entity by default: you report all income and expenses on Schedule C, and the LLC files no separate federal return.6Internal Revenue Service. Single Member Limited Liability Companies
Once your spouse becomes a second member, that ends. A domestic entity with two or more members defaults to partnership classification under federal regulations.7eCFR. 26 CFR 301.7701-3 – Classification of Certain Business Entities That default applies automatically unless you affirmatively elect otherwise.8Internal Revenue Service. LLC Filing as a Corporation or Partnership
Partnership Filing Requirements
A partnership does not pay income tax itself but must file Form 1065 each year, issuing a Schedule K-1 to each partner showing their share of profits, losses, deductions, and credits. Each spouse then reports their K-1 amounts on their individual Form 1040.9Internal Revenue Service. Partnerships
The partnership also needs its own EIN. If your single-member LLC was using your Social Security Number, you’ll need to apply for one, since the IRS treats a change in business structure or ownership as a reason to obtain a new EIN.10Internal Revenue Service.

The partnership filing obligation begins in the tax year the transfer takes effect. Set up partnership-level bookkeeping right away, track each spouse’s capital account, and be ready for the more involved 1065 at tax time. Late-filed partnership returns carry a penalty of $220 per partner per month.
Electing Corporate or S-Corp Treatment
If partnership taxation doesn’t suit you, the multi-member LLC can elect corporate classification by filing Form 8832.12Internal Revenue Service. About Form 8832 – Entity Classification Election Many couples then go further and elect S-corporation status, which keeps pass-through taxation while potentially reducing self-employment tax on distributions above a reasonable salary. That step requires Form 2553 and meeting S-corp eligibility rules.
The Qualified Joint Venture Election
Spouses who want to avoid partnership filing altogether may qualify for the qualified joint venture election. Under Section 761(f) of the Internal Revenue Code, a husband and wife who are the only members, who both materially participate, and who file a joint return can elect to treat the venture as two sole proprietorships instead of a partnership.13Office of the Law Revision Counsel. 26 USC 761 – Terms Defined Each spouse files a separate Schedule C, and no 1065 is required.
The Community Property Option
Under IRS Revenue Procedure 2002-69, spouses in community property states have a separate route. If the LLC is wholly owned by the couple as community property and no other person would be treated as an owner, they can choose to treat the entity as a disregarded entity.14Internal Revenue Service. Revenue Procedure 2002-69 The nine community property states are Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. Under this option, the LLC keeps filing exactly as it did as a single-member entity, with one spouse reporting everything on Schedule C.
Check Loans, Leases, and Other Contracts First
Before you sign anything, check the LLC’s outstanding loans, lines of credit, and commercial leases for change-of-control clauses. Many lenders and landlords treat a change in LLC membership as a potential default or require advance notice and consent. SBA loans in particular tend to include ownership-change restrictions. Transferring your interest without notifying the lender could technically put the loan in default even if payments are current. Review every major contract and contact the relevant parties before finalizing the transfer.
Self-Employment Tax After the Transfer
When a single-member LLC becomes a partnership, both spouses owe self-employment tax on their respective shares of partnership income. If you were already paying SE tax on the LLC’s full profit, the combined burden may not change much, but your spouse should be ready to make quarterly estimated tax payments on their share, including the 15.3% combined Social Security and Medicare tax on earnings up to the Social Security wage base and 2.9% Medicare tax above it. A qualified joint venture or S-corp election can meaningfully alter this calculation.
Choosing How Much to Transfer
Think carefully about the split. A 50/50 division gives both spouses equal say but can produce deadlocks on major decisions. A 51/49 division preserves a managing majority for one spouse while still granting the other meaningful ownership. Whatever ratio you choose, the amended operating agreement should spell out decision-making authority, distribution rights, and what happens if the marriage dissolves. Easier to work through now than during a dispute.
