Under IRC Section 469, a passive activity is any business or rental activity in which the taxpayer does not materially participate. All rental activities are presumed passive by default, regardless of how many hours the owner spends managing them — unless the taxpayer qualifies as a Real Estate Professional or uses short-term rentals in which they materially participate. This is a categorical rule, not a facts-and-circumstances test for ordinary rentals.
A loss from a passive activity can only offset income from other passive activities. It cannot reduce your wages, salary, self-employment income, interest, dividends, or capital gains (other than gains from passive activity dispositions). Passive losses that cannot be used in the current year are "suspended" and carried forward indefinitely until you have sufficient passive income or dispose of the activity.
Congress acknowledged that the strict passive loss rules could be overly harsh for small investors and carved out a partial exception: taxpayers with adjusted gross income below $100,000 can deduct up to $25,000 in rental losses against non-passive income each year, as long as they actively participate (a lower bar than material participation). This exception phases out ratably between $100,000 and $150,000 AGI.
For high earners — the physicians, attorneys, executives, and tech professionals who are most likely to have investable capital for real estate — the $25,000 allowance provides zero benefit. At $150,000 AGI or above, the exception is completely phased out. These investors can own rental properties that generate $300,000 in depreciation-driven losses every year, and none of it can be used to reduce their W-2 income without qualifying for REP status or the STR exception. The losses simply pile up as suspended carryforwards.
For taxpayers with modified AGI below $100,000, the $25,000 rental loss allowance is automatic upon active participation. Active participation is a low bar — you simply need to make management decisions about the property, such as approving tenants, setting rents, and authorizing repairs. You do not need to personally manage the property day-to-day.
As AGI rises from $100,000 to $150,000, the allowance phases out by $1 for every $2 of income above $100,000. At $125,000 AGI, the allowance is reduced to $12,500. At $150,000, it is $0. Married couples filing separately get no allowance at all, regardless of income. For investors in this phase-out range, it can be worth strategically managing their AGI — for example, through retirement contributions — to preserve some of the allowance.
Passive losses that are suspended do not disappear — they accumulate in a carryforward pool tracked on Form 8582. Each year's suspended losses are added to the pool. You can use these suspended losses in two ways before the property is sold: (1) they can offset passive income from other passive activities (such as passive partnership income or income from another rental where you have gains); (2) they can offset gains from passive activity dispositions.
The most common deployment of suspended losses is at sale. When you sell the property in a fully taxable disposition, all remaining suspended losses become immediately deductible against any type of income in the year of sale — even your W-2. This creates a large exit-year deduction that partially offsets the taxable gain and depreciation recapture. Investors sometimes refer to this as the "suspended loss release" — a pre-funded tax deduction that fires the moment you exit the investment.
For passive real estate investors sitting on large suspended loss pools, there are two primary exit paths. The first is a taxable sale where the suspended losses release and offset the gain. This is appropriate when the property has substantial appreciation that you want to realize, or when you want to exit the market entirely. The suspended losses help neutralize the tax cost of the gain and depreciation recapture.
The second path is the 1031 exchange, where you defer both the gain and the depreciation recapture by rolling into a new property. However, suspended losses from the old property do not automatically transfer to the new property. They remain suspended until you have passive income to absorb them or until you exit via a taxable sale. Many investors use a hybrid strategy: do several 1031 exchanges while building wealth, then sell a property outright in a year when suspended losses can fully absorb the taxable income.
Worked Example
The dentist owns a $1.2 million rental property generating $85,000 per year in depreciation-driven paper losses (accelerated in year one by cost segregation). His AGI is $380,000 — far above the $150,000 phase-out threshold. He does not qualify as a REP and the property is a long-term rental, so he cannot use the STR exception. Each year, $85,000 in losses is suspended and added to his Form 8582 carryforward pool. Over 5 years, he accumulates $425,000 in suspended losses. In year 6, he sells the property for $1.5 million, recognizing $300,000 in capital gains and $120,000 in depreciation recapture. The full $425,000 in suspended losses releases at sale, completely offsetting the $300,000 gain and $120,000 recapture, with $5,000 in excess losses applied against his ordinary income. The accumulated losses effectively make the sale nearly tax-free.
