A real sale still faces related-party character rules
A sale of property between a partnership and a person owning more than 50% of its capital or profits, directly or indirectly, can be subject to special rules. Losses generally are disallowed on the covered transactions. Gains can be ordinary when the property is not a capital asset in the transferee's hands, including depreciable or real property used in a trade or business. Similar rules apply to certain sales between partnerships under common ownership. An owner should therefore identify attribution and the buyer's intended use before treating a fair-market-price sale as an ordinary unrelated transaction. Paying actual cash does not remove the ownership rule. These provisions concern property other than the partnership interest itself; a sale of an ownership interest has its own analysis. Direct percentages alone can be misleading when family and entity attribution apply.
Compare loss disallowance with ordinary-gain treatment
Assume a 70% partner sells property with $100,000 tax basis to the partnership for its supported $75,000 fair market value. Under the covered related-party loss rule, the $25,000 loss generally is not deductible merely because the price is fair and cash is paid. In a second example, that partner sells equipment with $40,000 basis for $70,000, and the partnership will use it as depreciable business equipment. The $30,000 gain can be ordinary under the applicable controlled-partnership rule rather than capital gain. Other recapture and basis rules must still be coordinated. These examples assume the ownership and property facts meet the statute and do not involve an ownership-interest sale. A later buyer sale can have special treatment related to the previously disallowed loss, so retain the loss history instead of deleting it from the file.
Build the direct and attributed ownership map
List capital interests, profit interests, entity owners, trusts, and relevant family relationships for both sides of the transaction. Publication 541 describes attribution through entities and certain family members, including siblings, spouses, ancestors, and lineal descendants for this purpose. Do not import a narrower family definition from another tax rule. A person holding less than 50% directly can be treated as a more-than-50% owner after attribution. For two partnerships, test ownership of each rather than assuming different legal names make the sale unrelated. Preserve the ownership map as of the transaction date and document any contemporaneous changes. A transfer intended to avoid a related-party threshold requires analysis of its substance and applicable rules. Do not alter percentages on paper without changing real ownership rights and expect the tax treatment to follow automatically.
Coordinate the purchaser’s basis and later sale history
Record purchase price, adjusted tax basis, fair market value, liabilities, asset classification, and intended use. If a loss is disallowed, determine the proper partner-basis adjustments and subsequent gain-offset rules rather than increasing the purchaser's basis casually to the seller's historic amount. Keep a memorandum connecting the disallowed loss to the specific asset and later dispositions. A basis adjustment on an owner's partnership interest is different from inside basis in the purchased property. If the property later changes use or is sold, provide the original transaction file to the preparer so the related-party history is considered. Reconcile seller reporting, partnership asset records, and any financing documents. Installment terms and assumed liabilities can add timing issues without changing the need to establish ordinary character and loss disallowance first.
Compare a contribution or outside sale on real economics
Consider whether the business needs to buy the asset, receive a capital contribution, lease it under supported terms, or purchase from an unrelated supplier. Each route has distinct ownership, basis, allocation, and cash effects; a contribution is not a sale with the same tax result. Model the seller's recognized income, the partnership's cost and deductions, and changes in owner capital. Obtain actual valuation evidence and document approval by the affected owners. The practical decision is a supported transaction with the related-party tax result included in the price and funding plan. It is not a promise that an arm's-length price alone makes a controlled sale tax-neutral. Keeping ownership attribution and buyer use visible before closing prevents an expected capital gain or deductible loss from being replaced by an unexpected ordinary-income or disallowance result.
