Real Estate Limited Partnership Tax

A real estate limited partnership is a syndication vehicle that pools investor capital, purchases property, and distributes depreciation deductions and passive losses to partners for tax purposes. Once a common way for high-income earners to shelter ordinary income, its benefits were curtailed by passive activity loss rules introduced in 1986.

The RELP structure and flow-through taxation

A real estate limited partnership divides into two classes of partners. General partners manage the property and are liable for partnership debts; limited partners contribute capital but have no management role and limited liability. Unlike corporations, the partnership itself pays no federal income tax. Instead, partnership income, losses, and deductions flow through to each partner’s individual return in proportion to their ownership stake. This pass-through arrangement means depreciation deductions and operating losses generated by the property can shelter a partner’s other income—a feature that made RELPs highly attractive before 1986.

The mechanism is straightforward. A partnership acquires an apartment building for $10 million using $3 million of partner capital and $7 million of borrowed funds. The building generates $800,000 annual rental income. But the partnership deducts $600,000 in straight-line depreciation against that revenue. The resulting $200,000 of taxable income flows through to partners. Crucially, that $600,000 depreciation deduction was available to each partner on their own return, regardless of whether the partnership had positive cash flow. If expenses exceeded revenue, the partnership could report a loss, which would also flow through and could offset the partner’s other income—a wage, portfolio return, or active business profit.

This created a powerful tax shelter. A limited partner in a RELP could deduct losses well beyond their actual cash investment, using leverage embedded in the partnership’s debt to magnify deductions. A $1 million investment in a property purchased at 70% loan-to-value could produce tax losses of several million dollars over the first decade, as depreciation and early-period interest deductions dominated. For a partner in the highest marginal tax bracket, those deductions could be worth 50 cents on the dollar or more in tax savings.

The pre-1986 boom and the passive activity loss rules

This arbitrage between economically sound real estate and tax shelter demand drove explosive growth in RELP syndication through the 1970s and early 1980s. Promoters marketed partnerships explicitly as tax vehicles; some ventures made little economic sense but generated the desired loss deductions. This fed a real estate credit boom and overbuilding in certain markets. By the mid-1980s, Congress recognized that real estate tax shelters were eroding the tax base and favoured wealthy investors over wage earners who could not access equivalent deductions.

The Tax Reform Act of 1986 introduced passive activity loss rules, codified in IRC Section 469. These rules prohibit taxpayers from using passive losses to offset wages, interest, dividends, or other active income. Passive activities are broadly defined as any trade or business in which the taxpayer does not materially participate. A limited partner in a RELP has no management role, making the investment inherently passive. Any losses generated by the RELP now could be carried forward and used only to offset other passive income in future years—not current active income.

This single reform gutted the tax-shelter appeal of most RELPs. A $2 million loss from a partnership no longer provided immediate tax relief; it was suspended and useless until the partner generated enough other passive income (from another partnership, rental property, or other passive source) to absorb it. For many investors, that day never came, and losses were deducted only upon eventual sale of the partnership interest or final liquidation of the partnership itself.

At-risk rules and the $3 million cap

A second constraint preceded passive activity rules and remains in force. The at-risk rules, introduced in 1976 and tightened since, limit deductions to the amount of cash (or recourse debt) a partner has genuinely risked. If a partner invested $1 million but the partnership issued $5 million of nonrecourse debt (debt for which the partner bears no personal liability), the partner can deduct losses only up to the $1 million at-risk basis. Any additional losses are suspended under the at-risk limitation, separate from the passive loss limitation.

Most real estate partnerships rely on nonrecourse mortgages, where the lender’s recourse is limited to seizing the property. In those cases, a partner’s at-risk basis equals cash contributed plus any personal guarantee of debt. This rule prevents investors from claiming unlimited depreciation deductions on debt they don’t truly back.

Who still uses RELPs and how

Despite these constraints, RELPs remain in use, though typically not for tax-shelter arbitrage. Real estate investment trusts (REITs) have become the preferred vehicle for diversified real estate exposure, since they offer liquidity and transparency. But RELPs persist in private real estate syndication—especially large commercial or multifamily projects where the sponsor (general partner) seeks to raise capital from accredited and institutional investors.

In these modern partnerships, tax efficiency is a secondary goal. The primary motives are capital raising and alignment of sponsor and investor interests. The general partner typically keeps a 1–2% management fee and a larger “promote”—a disproportionate share of profits once investors recover their capital. Depreciation and losses still flow through to investors, but investors expect to be passive players subject to passive loss rules. Many sophisticated investors hold substantial other passive income (from prior partnerships, rental property, or mortgage-backed securities), so suspended losses eventually find use.

Depreciation recapture and exit taxes

Another tax consequence affects RELP investors at exit. When a partner sells or the partnership liquidates, any gains are ordinary income to the extent of prior depreciation deductions claimed—a process called depreciation recapture. If a partner deducted $2 million in depreciation over ten years and then sells the partnership interest for a $3 million gain, that gain includes a $2 million depreciation recapture component, taxed as ordinary income (at rates up to 25% on real property). This claws back some of the initial tax benefit and reminds investors that depreciation deductions are not eliminated; they’re deferred and recaptured at a potentially unfavorable rate.

For very low-income partners or those in low tax brackets, depreciation recapture can exceed the benefit of the initial deductions if tax rates have risen or if the partner’s income profile has changed by the time of sale.
