IRC §469 Passive Activity Loss

Where this comes from

In the early 1980s, tax shelters were a national pastime. High earners bought paper losses from real estate and other deals to wipe out salary income. Congress shut that down in the Tax Reform Act of 1986 with section 469, the passive activity loss rules.

The rule sorts your activities into passive and non-passive buckets. Losses from passive activities generally cannot touch wages, business income, or portfolio income. Rental activities were branded passive by definition, which is why this section sits in the middle of every cost segregation conversation.

What it established

The default is strict: a rental loss is passive no matter how hard you work on the property. Suspended losses carry forward and are generally released in full when you dispose of the activity. A modest relief valve in section 469(i) lets an active participant deduct up to $25,000 of rental loss, but it phases out as adjusted gross income rises above $100,000.

The big exception is the real estate professional rule in section 469(c)(7). If you spend more than half of your personal service time, and more than 750 hours a year, in real property trades or businesses in which you materially participate, your rentals are not automatically passive. Material participation in the rental itself then makes its losses non-passive.

A second path comes from the regulations. Under Treas. Reg. 1.469-1T(e)(3)(ii)(A), an activity where the average customer stay is seven days or less is not a rental activity at all. That is the short-term rental rule. The owner still has to materially participate, but the real estate professional test does not apply.

How it shows up in a study

A study can create a large first-year paper loss. Section 469 decides whether that loss does anything for you right now. For a W-2 earner with a regular long-term rental and no real estate professional status, the loss is usually suspended, and the study's value shifts to future years.

That is why we ask how you use and run the property before we talk numbers. A qualifying real estate professional, a materially participating short-term rental host, or an owner with other passive income to absorb the loss each gets very different value from the same study. The depreciation is the engine; section 469 is the transmission.

What it does not mean

Cost segregation does not beat the passive loss rules. No study changes your section 469 status. If the loss is passive, it stays passive, and anyone promising W-2 offset without checking your participation facts is selling past the truth.

The short-term rental path is also not automatic. The seven-day average must hold, material participation must be real and provable with time records, and the hours tests are heavily audited. Suspended losses are deferred, not destroyed, but deferred value is smaller than current value, and honest projections say so.
