Strategy Snapshot
Partnership tax offers flexibility that no other entity type can match — but that flexibility produces complexity. Outside basis, capital accounts, and allocations operate under different rules than S-corps, and the consequences of getting them wrong usually surface at the worst time: a loss year, a large distribution, or a sale.
Unlike S-corps, partnership debt increases a partner's outside basis — which is why partnerships are often better for leveraged investments like real estate.
Track the economics of each partner's interest. They must be maintained correctly for special allocations to be respected.
Partners pay tax on allocated income whether or not they received a cash distribution. This catches passive investors off guard every year.
Outside Basis
Outside basis is a partner’s tax basis in their partnership interest. It is the running total of what the partner has invested, earned, borrowed through the partnership, and taken out. It determines how much loss is currently deductible and what happens tax-wise when money comes out.
Outside basis increases with:
- Cash contributions to the partnership
- Adjusted basis of property contributed
- Income and gain allocated to the partner (including tax-exempt income)
- The partner’s share of partnership debt (recourse and nonrecourse)
Outside basis decreases with:
- Cash distributions received
- Allocated losses and deductions
- The partner’s share of debt decreases
- Distributions of property (at the property’s adjusted basis)
Outside basis cannot go below zero. Losses in excess of basis are suspended and carry forward until basis is restored.
How Debt Affects Basis — The Key Difference from S-Corps
Partners get outside basis from their share of partnership debt. This is one of the most significant structural advantages of partnership taxation for leveraged investments.
Recourse debt is allocated to the partner who bears the economic risk of loss — typically a general partner or a partner who has personally guaranteed the obligation.
Nonrecourse debt is generally allocated in proportion to profit-sharing ratios, with additional rules for property that carried built-in gain at the time of contribution.
Capital Accounts
Capital accounts are separate from outside basis. Where outside basis is a tax concept, capital accounts are an economic concept — they track each partner’s equity position in the partnership.
Capital accounts increase with:
- Cash contributions
- Fair market value of contributed property (book value, not tax basis)
- Allocated book income
Capital accounts decrease with:
- Cash distributions
- Fair market value of distributed property
- Allocated book losses
Capital accounts matter because they govern liquidation. If the partnership agreement provides that liquidating distributions are made according to positive capital account balances — which is the standard required for most special allocations to be respected — then a partner with a zero or negative capital account receives nothing (or must contribute to cover the deficit) when the partnership winds down.
Special Allocations
Partnerships can allocate income, gain, loss, and deduction in ratios that do not match ownership percentages. This flexibility is one of the main reasons partnerships are used for real estate and investment deals with multiple parties bringing different contributions to the table.
For a special allocation to be respected, it generally must have substantial economic effect:
Effect: The allocation must be reflected in capital accounts. If Partner A receives an extra 30% of depreciation, Partner A’s capital account must decrease by that amount.
Economic: At liquidation, distributions must be made according to positive capital account balances. The allocation must have real economic consequences for the partners.
Substantial: The allocation must not be designed primarily to shift tax benefits between partners without shifting economic consequences. An allocation that gives tax losses to a high-bracket partner but has no meaningful economic effect will likely fail.
If a special allocation lacks substantial economic effect, the IRS reallocates it according to the partners’ interests in the partnership — often reverting to ownership percentages.
A special allocation that survives scrutiny looks like real economics: it changes what each partner gets in a liquidation, not just who reports what on a tax return.The practical test
Guaranteed Payments
Guaranteed payments are amounts paid to a partner for services or the use of capital, determined without regard to partnership income. They are fixed — the partner receives them whether the partnership is profitable or not.
Tax treatment:
- Ordinary income to the recipient partner
- Subject to self-employment tax if paid for services
- Deductible by the partnership, reducing the income allocated to other partners
- Reported on the partner’s K-1 separately from distributive share items
Guaranteed payments are common in partnerships where one partner contributes management or services and receives a base amount before any profit-sharing occurs. They are also common in real estate partnerships where a preferred return to a capital partner is structured as a guaranteed payment rather than a priority allocation.
Phantom Income
Phantom income is taxable income allocated to a partner with no corresponding cash distribution. It happens when the partnership earns taxable income but retains cash for operations, debt service, or reinvestment.
A simple example:
A real estate partnership generates $300,000 of taxable income in a year but uses all of it to pay down the mortgage. No cash is distributed to partners. Each partner still receives a K-1 with their share of the $300,000 and must report and pay tax on that income.
Phantom income is not unusual or wrong — it is a predictable feature of pass-through taxation. But it consistently catches passive investors off guard, particularly in early-stage real estate partnerships where depreciation deductions in prior years reversed and income is now flowing through.
Planning implication: Partners in leveraged entities should anticipate the timing mismatch between cash flow and taxable income, particularly in deals where depreciation runs out or assets are refinanced.
Common Problems We See
- Capital accounts not maintained — means special allocations cannot be defended and the operating agreement may not work as intended at liquidation
- Partner loan recorded as a capital contribution — affects the partner’s basis and the economic terms of the deal
- Guaranteed payment vs. distributive share confusion — wrong classification changes self-employment tax treatment and how the payment interacts with the partnership’s deductions
- Phantom income in a cash-poor year — partners who did not model the taxable income separate from distributions are caught underprepared at filing
- Debt allocation changes ignored — refinancing or paying down debt changes partners’ outside basis and must be tracked carefully
