Real estate deals rarely have just one owner anymore. Most co-investments I see are held through an LLC or limited partnership taxed as a partnership under the tax code. That structure is popular for good reason, but it also brings tax concepts that catch investors off guard if nobody explains them up front.
I want to walk through the basics here, not to make you a tax expert, but so you know the right questions to ask before you sign a partnership or operating agreement.
1. Why partnerships are the default vehicle
Partnership taxation under Subchapter K generally avoids the entity-level tax that corporations pay. Income, losses, deductions, and credits flow through to the owners and are reported on their own returns.
For real estate specifically, this pass-through treatment lets investors use depreciation and other deductions personally, rather than trapping them inside the entity. That is a major reason LLCs and limited partnerships dominate real estate ownership structures.
2. Understanding basis
Your basis in the partnership is essentially your tax investment in the deal. It starts with what you contributed, and it moves up and down over time based on income allocated to you, losses allocated to you, distributions you receive, and your share of partnership debt.
Basis matters because it limits how much loss you can deduct and affects the tax consequences when you eventually sell your interest or the property is sold. Investors are often surprised to learn that a distribution can trigger taxable gain if it exceeds their basis.
3. Capital accounts versus basis
Capital accounts and tax basis are related but not identical. A capital account is a bookkeeping record maintained under the partnership agreement, generally tracking contributions, allocated income and loss, and distributions.
Basis includes those same items but also factors in your share of the partnership's liabilities. Two partners can have very different basis numbers even with similar capital accounts, largely because of how debt is allocated among them. This is a detail worth understanding before you rely on either number to plan your own taxes.
4. Special allocations and why they exist
Partnerships are not required to split income and loss in the same percentages as ownership. A partnership agreement can allocate specific items differently among partners, as long as the allocations have what the tax code calls "substantial economic effect."
This flexibility is useful in real estate. A partner who contributed the land might be allocated depreciation differently than a partner who contributed cash. But special allocations have to be drafted carefully, or the IRS can disregard them and reallocate income according to the partners' overall economic interests instead.
5. Why the partnership agreement matters so much
A well-drafted partnership or operating agreement is not boilerplate. It should address how capital accounts are maintained, how special allocations work, how debt is allocated for basis purposes, and what happens when a partner wants out.
Most disputes I see among real estate co-investors trace back to an agreement that was too thin on these details, or that was copied from another deal without thinking through how it applied here. Getting this right at formation is far cheaper than untangling it after a disagreement or an audit.
If you are structuring a real estate co-investment or reviewing an agreement you have already been asked to sign, reach out through blgattorney.com or call my Oklahoma City office. It helps to have someone look at the tax mechanics before the deal closes, not after.
