When one owner buys out the other owner of a two-member LLC taxed as a partnership, agreeing on the price is only part of the work. The seller needs to understand the tax bill and when it comes due. The buyer needs to understand the tax basis of the assets being acquired. The partnership needs a supported final return if the transaction ends its partnership status.
Those answers should fit together before the owners commit to the deal.
This article draws on a real partnership-buyout case we worked on at JAG. The owners and company are given fictional names, and identifying details, dates, and dollar amounts are omitted. The account focuses on the planning and reporting issues; the final closing, filings, and tax outcome have not been confirmed for this article.
The situation: two owners, one continuing business
The two owners, whom we’ll call Daniel Reed and Marcus Lane, each held half of a business we’ll call Cedar Lane Services LLC. The business was taxed as a partnership. The plan was for Daniel to buy Marcus’s entire interest and continue as the sole owner, with payments over time. Negative capital in the records added another reporting question.
The case raised practical questions: Could Marcus spread out the tax as he got paid? Would Daniel get a new tax basis in the business assets? What would happen to the partnership return and the negative capital accounts?
Before answering any of those questions, the agreement needs to answer a more basic one: Who is buying Marcus’s interest?
Start with the buyer named in the agreement
The planning history included two structures: a company redemption and a proposed personal purchase by Daniel. In a personal purchase, called a cross-purchase, Daniel buys Marcus’s interest. In a redemption, the company acquires the departing owner’s interest and becomes responsible for the payments. Those structures can produce different tax consequences, even if Daniel ultimately runs the same business.
For a cross-purchase in which one existing partner buys the other partner’s entire interest, the starting authority is Revenue Ruling 99-6, Situation 1. The seller generally reports a partnership-interest sale. The continuing buyer is treated as receiving assets for the buyer’s original interest and purchasing the asset portion attributable to the departing owner. The ruling uses simplified facts; debt and assets that can produce ordinary income require additional analysis. IRS Revenue Ruling 99-6, pages 6–7
A company redemption needs its own analysis. An installment redemption can leave a retiring owner treated as a partner until the interest has been fully liquidated. That can change when the final partnership return is appropriate. Treasury Regulation §1.736-1(a)(6)
For Daniel and Marcus, this means the purchase agreement, note, actual payments, and tax reporting must tell the same story. Calling a company payment a personal purchase in the bookkeeping does not settle the question.
Negative capital does not tell you the seller’s tax bill
A capital account is one record of an owner’s investment and allocated results. Outside basis is the owner’s tax basis in the partnership interest. The two amounts can differ, including because outside basis generally reflects the owner’s share of partnership liabilities and other partner-specific adjustments. IRS Form 1065 instructions, Item L
So Marcus’s negative capital balance does not, by itself, establish his gain, mean he must contribute cash, or tell Daniel the tax basis of the acquired assets.
The useful next step is a reconciliation. Bring together the books, tax capital, each owner’s outside basis, the debts, and the proposed transaction. If the final partnership records should close at zero, explain the supported transfers and distributions that get them there. An entry invented solely to remove a deficit will leave the next preparer with the same unanswered question.
The operating business may still have cash, equipment, and loans after its partnership tax reporting ends. Its ongoing records need to connect to the tax closeout and the successor’s opening records.
Payments over time do not guarantee taxes over the same period
Marcus may qualify to report eligible gain using the installment method. But the part of partnership-interest gain attributable to certain receivables, inventory, and depreciation recapture is treated as ordinary income and cannot simply be deferred with the note payments. These are often called hot assets. IRS Publication 537, “Sale of Partnership Interest”
Debt matters, too. Relief from qualifying debt can affect the installment calculation, and debt above the relevant installment basis can create a sale-year payment for tax purposes even without a cash payment of that amount. Interest must also be separated from the purchase price. Treasury Regulation §15a.453-1(b)(2)–(3)
Before Marcus accepts the payment schedule, he needs a projection showing what tax could be due in the year of sale and how much cash he will have available to pay it. A note can help finance a buyout while still leaving the seller with an immediate cash need.
The buyer needs an asset schedule that reflects both interests
Daniel’s original ownership and his newly purchased ownership need separate basis calculations. The liquidation rules determine the asset basis attributable to his original interest. The acquired portion generally follows purchase-cost rules. It is not enough to copy half of every old depreciation balance and then add the purchase price to a single account. IRS Revenue Ruling 99-6, Situation 1
Where the transaction is an applicable deemed asset acquisition, the buyer’s allocation can also require Form 8594. The IRS instructions specifically distinguish a partnership-interest purchase treated as an asset purchase from an ordinary interest transfer. IRS Form 8594 instructions, “Who Must File”
This matters after closing. Daniel needs records that support future depreciation, amortization where applicable, and gain or loss when an asset is later sold. The final partnership return and those successor records should be prepared as coordinated parts of the transaction.
Give side payments and later elections their own review
The proposed arrangement also included an additional payment to Marcus tied to a future business receipt. The specific receipt and terms are omitted here for privacy. The collection by the business and the payment to Marcus are two separate events. The agreement needs to identify who owes the payment, what it represents, and whether it changes the total purchase consideration. A contingent purchase-price term may change the installment calculation and later asset-allocation reporting. Installment-sale regulations, §15a.453-1(c); Form 8594 instructions, changes in consideration
The plan also contemplated having the LLC taxed as a corporation. That added another decision. The election has effective-date and filing requirements. The treatment of contributed assets and liabilities needs review, including possible gain when counted liabilities exceed adjusted tax basis. A negative book balance alone does not answer that test. IRS Form 8832 and instructions; IRC §357(c)
The buyout, payment obligations, and any classification election need a documented sequence. A desired effective date should be supported by what the parties actually agreed to and carried out.
What to bring to the planning conversation
Before signing—or before filing a return for a buyout already completed—bring your CPA and transaction attorney the same set of records:
- The operating agreement, purchase or redemption agreement, amendments, and proposed or executed closing documents.
- The note, payment schedule, interest terms, and evidence of payments already made.
- The latest tax returns, capital and outside-basis schedules, and a detailed debt list.
- The asset and depreciation schedules, receivables, inventory, and available valuation support.
- Any side-payment provisions and entity-classification elections.
Ask for an explanation of the seller’s tax and cash needs, the buyer’s asset basis, the partnership’s final reporting, and the responsibilities that continue after closing. This real case illustrates why those questions belong in one coordinated review. Its value here is the planning lesson; no completed transaction or tax savings result is claimed.
If the ownership change is between family members, our family-business succession planning case examines personal goodwill, seller financing, and operating cash in an S-corporation setting. Those rules differ from the partnership rules discussed here.
If an ownership change is on your calendar, JAG’s tax-planning services can be a starting point for discussing the decision and defining the work. Transaction analysis, annual return preparation, and bookkeeping are separately scoped. You can request a consultation, complete the questionnaire, and have Joe review the request before an appointment is confirmed.
