To transfer LLC ownership to a spouse, you amend the company’s operating agreement, sign an Assignment of Membership Interest, and update your filings with the state. If you were the sole owner, the transfer also changes how the IRS classifies the LLC, moving it from a disregarded entity to a partnership with new filing duties. The tax side is usually the easy part: federal law lets U.S. citizen spouses give each other property of any value with no gift tax owed and, in most cases, no gift tax return to file.
Start With the Operating Agreement
Every LLC transfer begins with what the operating agreement says. That document controls who can receive a membership interest, what approvals the transfer requires, and whether any restrictions apply. In a multi-member LLC, the agreement often requires the other members to consent, or gives them a right to match the terms of your transfer. Some agreements carve out an exception for transfers to immediate family, but you can’t assume yours does without reading the language.
If you’re the sole member, consent is a non-issue, but the agreement may still impose conditions such as a written notice or a formal valuation. If it’s silent on spousal transfers, amend it before you move forward. An amendment typically takes a written resolution signed by all current members and should explicitly authorize the transfer and describe the new ownership structure.
If your LLC never adopted an operating agreement at all, your state’s default LLC statute takes over. Most states allow free assignment of economic rights but don’t automatically grant the recipient full membership status. That gap matters, and it drives the next step.
Sign an Assignment of Membership Interest
The document that actually moves ownership is the Assignment of Membership Interest. It’s a standalone legal instrument, separate from anything you file with the state, and it’s the definitive proof of the transaction. Every subsequent tax and administrative step traces back to it.
The assignment should spell out:
- The exact percentage transferred, whether 50%, 100%, or another share.
- Whether the transfer is a gift or a sale, and if a sale, the price and payment terms.
- The effective date, which determines when tax obligations shift.
- Signatures of both the transferring member and the receiving spouse.
If it’s a gift, state that the interest is conveyed without monetary consideration. Don’t leave this ambiguous. The gift-versus-sale distinction directly affects how you report the transaction and how your spouse’s basis in the interest is calculated.
Assignee vs. Full Member
Here’s the step most people miss. In most states, assigning a membership interest transfers only economic rights, meaning your spouse’s share of profits, losses, and distributions. It does not automatically give voting power, management authority, or any other governance right. Your spouse becomes an “assignee” rather than a full “member” unless the operating agreement or a unanimous member vote specifically admits them.
For a single-member LLC where you’re handing over your entire interest, this is less of a practical hurdle because there’s no one else to object. Even so, the amended operating agreement needs to formally list your spouse as a member with full rights. In a multi-member LLC, the other members may need to vote on whether your spouse joins as a full member or stays a passive assignee. An assignee with no vote is in a very different position than a member who can participate in decisions, so nail this down in the paperwork.
Gift Tax Between Spouses
If you’re gifting the interest rather than selling it, the IRS treats the transfer as a gift valued at the interest’s fair market value on the date of conveyance. Ordinarily, a gift like this would require the donor to file Form 709, the federal gift tax return.
The Marital Deduction Zeros It Out
Federal law provides a complete exemption for gifts between U.S. citizen spouses. Section 2523 of the Internal Revenue Code allows a deduction equal to the full value of any property transferred by gift to a spouse who is a U.S. citizen, effectively reducing the taxable gift to zero regardless of the amount.1Office of the Law Revision Counsel. 26 USC 2523 – Gift to Spouse You could gift an LLC interest worth $5 million and owe no gift tax.
In most cases you don’t even need to file Form 709. The IRS instructions explicitly state that you do not have to file a gift tax return for gifts to your U.S. citizen spouse, with narrow exceptions for certain “terminable interests” or when making a qualified terminable interest property (QTIP) election.2Internal Revenue Service. Instructions for Form 709 (2025) A straightforward gift of an LLC membership interest doesn’t 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 Instead, Congress provides a much larger 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 the LLC interest exceeds that threshold, you 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. What’s New – Estate and Gift Tax
Your Spouse’s Tax Basis
When your spouse receives the LLC interest as a gift, their basis is the same as yours was at the time of the transfer, known as carryover basis. If you originally invested $50,000 and the interest is now worth $200,000, your spouse’s basis remains $50,000. 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 If instead you sell the interest to your spouse at fair market value, their basis equals the purchase price. That may produce a better result on a future sale, but the sale is a taxable event for you now.
How the Transfer Changes Your LLC’s Tax Status
This is where the real complexity lives. As a sole owner, the IRS currently treats your LLC as a disregarded entity. You report income and expenses on Schedule C of your personal return, and the LLC files no separate tax return.6Internal Revenue Service. Single Member Limited Liability Companies
The moment your spouse becomes a second member, that changes. Under federal regulations, a domestic entity with two or more members defaults to partnership classification.7eCFR. 26 CFR 301.7701-3 – Classification of Certain Business Entities That default applies automatically unless you affirmatively elect a different classification.8Internal Revenue Service. LLC Filing as a Corporation or Partnership
Partnership Filing Requirements
A partnership doesn’t pay income tax itself, but it must file an annual informational return on Form 1065 and issue 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 Employer Identification Number. If your single-member LLC had been using your Social Security Number, you’ll need to apply for an EIN. The IRS lists a change in business structure or ownership as a general reason to obtain one.10Internal Revenue Service. Get an Employer Identification Number You can apply online or by filing Form SS-4.11Internal Revenue Service. Instructions for Form SS-4
The partnership filing obligation begins in the tax year the transfer takes effect. That means partnership-level bookkeeping right away, tracking each spouse’s capital account, and preparing for a more involved return at tax time. Late partnership returns carry a penalty of $220 per partner per month, so don’t defer setting this up.
The Qualified Joint Venture Election
Spouses who want to avoid partnership filing may qualify for the qualified joint venture election. Under Section 761(f), a husband and wife who are the only members of a business, who both materially participate, and who file a joint return can elect to treat the venture as two sole proprietorships rather than a partnership.12Office of the Law Revision Counsel. 26 USC 761 – Terms Defined Each spouse reports their share on a separate Schedule C, and no Form 1065 is required.
The Community Property Option
Spouses in community property states have a second option under IRS Revenue Procedure 2002-69. If the LLC is wholly owned by the couple as community property, and no other person would be considered an owner for tax purposes, the spouses can choose to treat the entity as a disregarded entity.13Internal 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 files exactly as it did when it was single-member, with one spouse reporting everything on Schedule C.
Electing Corporate Treatment
If partnership taxation doesn’t fit, the multi-member LLC can elect corporate classification by filing Form 8832.14Internal Revenue Service. About Form 8832 – Entity Classification Election Many couples 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 election requires Form 2553 and meeting the S-corp eligibility requirements.
Update State Records and Internal Books
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. Fees generally fall in the $25 to $100 range, and most states accept electronic submissions.
Failing to update state records can lead to penalties or even administrative dissolution. The state recognizes only the members listed in its files, so any delay creates a gap between legal ownership and the public record. File promptly.
Internally, the LLC should keep a Member Register that logs all owners, their ownership percentages, and their capital contributions. Update it to reflect the transfer, and store the signed assignment in the LLC’s permanent records alongside the amended operating agreement. This paper trail is your evidence of a clean chain of ownership, which matters if the LLC’s liability protection is ever challenged.
One filing you can skip: as of March 2025, domestic LLCs are exempt from beneficial ownership information reporting to FinCEN under the Corporate Transparency Act. An interim rule removed the requirement for all U.S.-formed entities, so no BOI report is due after the ownership change.15FinCEN.gov. Beneficial Ownership Information Reporting
Practical Issues to Handle Before You Sign
Check Loan and Contract Clauses
If the LLC has outstanding loans, lines of credit, or commercial leases, check those agreements 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 are especially likely to include ownership-change restrictions. Transferring 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 on Both Sides
When a single-member LLC becomes a partnership, both spouses owe self-employment tax on their respective shares of partnership income. If you were the only one paying SE tax on the LLC’s profits before, the total 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 shift this significantly.
Valuation
If the LLC interest has significant value and you’re gifting it, consider getting a professional valuation. For most spousal gifts between U.S. citizens, the marital deduction eliminates any tax consequence regardless of value. A documented valuation still protects you if the IRS ever questions the transfer, and it fixes the carryover basis with precision. For non-citizen spouse transfers that exceed the enhanced annual exclusion, an accurate valuation is essential because it determines how much of your lifetime exemption the gift consumes.
How Much to Transfer
Think carefully about the split. A 50/50 division gives both spouses equal say but can create deadlocks on major decisions. A 51/49 split preserves a managing majority for one spouse while granting the other meaningful ownership. Whatever you choose, make sure the amended operating agreement addresses decision-making authority, distribution rights, and what happens if the marriage dissolves. Those aren’t pleasant conversations, but they’re much easier to have now than during a dispute.
