Partnership to LLC Conversion: Debt, Basis, and SE Tax Rules

Converting a general partnership to a multi-member LLC is generally a non-taxable event for federal income tax on the partnership to LLC conversion, because the IRS treats both entities the same way: as partnerships. The tax year does not close, no new taxpayer identification number is required, and Section 721 shields the transfer of assets from gain or loss. One trap catches owners off guard more than any other, though: the way partnership debt is reclassified during the conversion can produce phantom income and a real tax bill, even when no cash moves.

Why the IRS Treats the Conversion as a Continuation

A domestic LLC with two or more members is automatically classified as a partnership for federal tax purposes unless it files Form 8832 to elect corporate treatment.1Internal Revenue Service. LLC Filing as a Corporation or Partnership Because both the old entity and the new one are taxed as partnerships, the IRS sees the conversion as a continuation of the same entity rather than a liquidation followed by a formation. Revenue Ruling 95-37 established that the converting partnership’s tax year does not close, the entity keeps its EIN, and the same tax consequences apply regardless of how the conversion is structured under state law.2Internal Revenue Service. IRS Private Letter Ruling 201605004

The non-recognition rule is Section 721 of the Internal Revenue Code, which says no gain or loss is recognized when property is contributed to a partnership in exchange for a partnership interest.3Office of the Law Revision Counsel. 26 USC 721 – Nonrecognition of Gain or Loss on Contribution Under the “assets-over” analysis of the conversion, the old partnership is treated as contributing all its assets and liabilities to the new LLC in exchange for membership interests, then distributing those interests to the partners in liquidation. Section 721 shields the contribution step, and the continuation treatment shields the rest. No federal income tax attaches to the conversion itself.

The Debt Reclassification That Can Trigger Real Tax

Here is where owners get tripped up. In a general partnership, every partner is personally on the hook for partnership debts. That personal exposure makes the debt “recourse” for tax purposes, and each partner’s share of recourse debt is included in their tax basis in the partnership. Once the partnership converts to an LLC, members gain limited liability protection and are no longer personally liable for the entity’s obligations. The debt is reclassified from recourse to nonrecourse.

Section 752 treats any decrease in a partner’s share of partnership liabilities as a deemed cash distribution to that partner.4Office of the Law Revision Counsel. 26 USC 752 – Treatment of Certain Liabilities When debt shifts from recourse to nonrecourse, the allocation among partners often changes. A partner whose allocated share drops experiences a deemed distribution equal to the decrease. No money moves. The tax code treats it as if cash did.

Section 731 then does the damage. If that deemed cash distribution exceeds the partner’s adjusted basis in their partnership interest, the excess is taxable as capital gain.5Office of the Law Revision Counsel. 26 USC 731 – Distribution to Extent of Gain The scenario is most common where one partner personally guaranteed a large loan. Under the recourse rules, that guarantee caused the full loan amount to be allocated to the guarantor, inflating their basis. When the LLC structure removes the personal guarantee, the liability gets reallocated across all members based on profit-sharing ratios, and the former guarantor can face a deemed distribution that exceeds their remaining basis. The resulting capital gains tax is real, and it is owed for the year the conversion takes effect.

Partners carrying large personal guarantees should model the liability reallocation before the conversion closes. In some cases the exposure can be managed by contributing additional capital to build basis before the conversion, or by structuring a “bottom-dollar” guarantee that keeps some recourse treatment. Getting the math wrong here is expensive.

Basis and Holding Period Carry Over

Because the conversion is a continuation rather than a new entity formation, each member’s tax basis in their LLC interest equals the adjusted basis they held in their partnership interest. Section 722 provides that the basis of a partnership interest acquired by contribution equals the adjusted basis of the contributed property plus any gain recognized.6Office of the Law Revision Counsel. 26 USC 722 – Basis of Contributing Partners Interest On the entity side, Section 723 gives the LLC a carryover basis in the assets it receives, equal to the partnership’s old adjusted basis in those assets.7Office of the Law Revision Counsel. 26 USC 723 – Basis of Property Contributed to Partnership

The practical effect is that depreciation schedules, built-in gain or loss on assets, and each partner’s individual basis all continue uninterrupted. There is no step-up or step-down. The holding period tacks, so the time you held the partnership interest counts toward the holding period of your LLC interest. That matters when you later sell, because the long-term capital gains rate requires holding for more than one year.

Self-Employment Tax After the Switch

Members of an LLC taxed as a partnership are treated the same as partners in a traditional partnership for self-employment tax. Members who perform services for the business are self-employed, not employees, and owe self-employment tax on their share of the LLC’s income.8Internal Revenue Service. Are Partners Considered Employees of a Partnership or Are They Considered Self-Employed For 2026, the Social Security portion applies to the first $184,500 of net self-employment earnings, plus the 2.9% Medicare tax on all earnings with no cap.9Social Security Administration. Contribution and Benefit Base

Former general partners who were fully subject to self-employment tax before the conversion continue to be subject to it after. The IRS looks at what the member actually does, not the title in the operating agreement. A member who actively manages the business and provides significant services is treated like a general partner. Only members who genuinely function as passive investors, with no management authority and no significant services, may qualify for the limited-partner exception. Members in service-based businesses such as law firms, medical practices, and consulting firms generally cannot claim limited-partner status no matter how they participate.

At-Risk Amounts and Suspended Losses

The conversion can also affect the amount each member is considered “at risk” under Section 465. Partners are generally at risk for recourse debts they are personally obligated to repay. When the conversion shifts debt from recourse to nonrecourse, a member’s at-risk amount may drop, and a lower at-risk amount limits the losses the member can deduct against income from the activity. If state law requires a former general partner to remain personally liable for recourse debts incurred before the conversion, those debts may continue to count toward the at-risk amount during that liability period.

Suspended passive activity losses under Section 469 are not wiped out by the conversion.10Office of the Law Revision Counsel. 26 USC 469 – Passive Activity Losses and Credits Limited Losses that were disallowed in prior years because the partner did not materially participate carry forward into the LLC. They remain suspended, available to offset future passive income from the same activity, or become fully deductible when the member disposes of their entire interest in a taxable transaction. The conversion itself is not a disposition, so it does not release those losses.

EIN and Form 1065 Continuity

An LLC that keeps the default partnership classification continues using the former partnership’s Employer Identification Number. The IRS does not require a new EIN when you convert a partnership to an LLC classified as a partnership.11Internal Revenue Service. When to Get a New EIN The entity keeps filing Form 1065, and each member receives a Schedule K-1 reflecting their share of income, deductions, and credits.

A new EIN is required only if the LLC elects to be taxed as a corporation, or if the conversion somehow leaves a single-member LLC that would be treated as a disregarded entity. Keeping the same EIN keeps payroll records, bank accounts, and vendor tax reporting linked to the existing number.

State Tax Traps to Check Before Filing

Federal treatment is relatively uniform. State-level consequences vary, and a few can surprise you. Many states follow federal treatment and recognize the conversion as a non-taxable continuation, but two categories of state cost deserve attention.

Some states impose franchise taxes, annual LLC fees, or gross receipts taxes on LLCs that did not apply to the former partnership. These are not triggered by the conversion itself, but they are an ongoing cost that changes your tax picture going forward. Check your state’s LLC fee structure before you file.

The bigger trap is real estate transfer tax. If the partnership owns real property, some states treat the conversion as a transfer and impose a documentary stamp or transfer tax. Other states exempt transfers between related entities or statutory conversions from the tax. The rules vary widely, so any partnership holding real estate should confirm with a tax professional whether the conversion triggers a transfer tax where the property is located.

Choosing a Different Tax Classification

The default partnership classification preserves continuity, but a multi-member LLC can elect to be taxed differently. Two options exist beyond the default.

  • Electing C corporation treatment by filing Form 8832. Corporate tax applies to the entity’s income, and distributions to members are taxed again as dividends. The double layer of tax makes this election uncommon for small businesses, though it can benefit companies that plan to reinvest most profits rather than distribute them.12Internal Revenue Service. About Form 8832 Entity Classification Election
  • Electing S corporation treatment by first electing corporate status, then filing Form 2553. Income passes through to members, but members who work in the business pay themselves a reasonable salary subject to payroll taxes, and distributions above that salary are not subject to self-employment tax.13Internal Revenue Service. About Form 2553 Election by a Small Business Corporation

The S corporation election comes with limits: no more than 100 shareholders, only one class of stock, and no nonresident alien owners. It also eliminates much of the allocation flexibility that makes partnership taxation attractive, because S corporation income must be allocated strictly by ownership percentage. Model the self-employment tax savings against the added compliance costs and lost flexibility before making the election. Any election that moves the entity out of partnership classification will require a new EIN and will end the continuation treatment that makes the default conversion tax-free.
