Tax & Structure
Passive activity losses and why the tax benefit may not apply to you
The rule that determines whether your rental losses reduce this year’s tax bill or sit unused for a decade.

Rental property frequently produces a taxable loss even while generating positive cash flow, because depreciation is a deduction that does not consume cash.
Whether that loss reduces your tax bill this year depends on rules that a great many investors discover only after their first return.
The general rule
Under United States law, rental activities are generally treated as passive regardless of how much time you spend on them.
Passive losses can generally only offset passive income. They cannot offset wages, business income in which you materially participate, or portfolio income such as interest and dividends.
Losses that cannot be used are suspended and carried forward indefinitely, available against future passive income from any source, or released on a fully taxable disposition of the activity.
So the benefit is not lost. It is deferred, sometimes for a very long time.
The special allowance
There is a limited exception permitting certain taxpayers who actively participate in rental real estate to deduct a capped amount of rental losses against ordinary income.
Active participation is a lower standard than material participation. It generally requires bona fide involvement in management decisions — approving tenants, setting rental terms, approving expenditures — and can be satisfied even where a management company handles operations.
The allowance is subject to an income phase-out, and above a defined level of modified adjusted gross income it is eliminated entirely.
This is the point that surprises high earners. The taxpayer with substantial employment income, for whom a deduction would be most valuable, is generally the one who cannot take it.
The specific dollar thresholds should be confirmed for the current year with a tax professional.
Real estate professional status
The exception that removes the passive characterization, and it is frequently claimed incorrectly.
The statutory tests generally require that, for the taxable year, more than half of the personal services the taxpayer performs in all trades or businesses are performed in real property trades or businesses in which they materially participate, and that they perform more than a substantial threshold of hours in such businesses.
Both tests must be met. And meeting them does not automatically make rental losses non-passive — the taxpayer must also materially participate in the rental activities themselves, which is why the election to aggregate all rental activities as a single activity is commonly made.
Several practical points.
Someone with a full-time job outside real estate will generally struggle to meet the more-than-half test, because their hours in the other occupation exceed their real estate hours.
Hours must be documented contemporaneously. Reconstructed logs prepared after an examination began have repeatedly been rejected.
Investor activities — studying financial statements, reviewing operations in a non-management capacity — are generally excluded from the hour count.
This status is scrutinized, litigated frequently, and lost frequently. It should be claimed only with professional advice and proper records.
The short-term rental consideration
A distinct area worth knowing about.
Under the regulations, an activity is not a rental activity where the average period of customer use is seven days or less, or where it is thirty days or less and significant personal services are provided.
Where an activity falls outside the definition of a rental activity, the general material participation rules apply rather than the automatic passive characterization for rentals.
This has attracted considerable attention in short-term rental circles. It is a genuine provision, it is more technical than the summaries suggest, and material participation must still be established and documented.
Treat any online description of it with caution and get professional advice.
Grouping elections
Taxpayers may in certain circumstances group activities together, which affects both material participation testing and the treatment of dispositions.
Elections have consequences that persist across years and can be difficult to revoke.
Another area for professional advice rather than self-direction.
What happens on sale
The useful part.
On a fully taxable disposition of the entire interest in an activity, suspended passive losses from that activity are generally released and become available.
Which means an investor with years of suspended losses may find a substantial deduction available in the year of sale, offsetting a portion of the gain.
This is worth planning around. Selling one property may release suspended losses that offset gain on another, and the sequencing can matter.
Note that the rules on which losses are released, and against what, are technical.
The practical implication
Do not buy rental property primarily for the tax deduction unless you have confirmed that you can actually use it.
For a high earner with employment income and no other passive income, the answer is frequently that the deduction is suspended and provides no current benefit.
That does not make the property a bad investment. It makes the tax argument in the sales presentation inapplicable to you specifically.
Ask your accountant before purchase, not in April.
