Passive Activity Loss Rules: Why Rental Losses Get Stuck

The default rule: rental activity equals passive

IRC 469 divides income and loss into two buckets: passive and non-passive. Passive losses can only offset passive income. They cannot touch W-2 wages, business profit, interest, dividends, or capital gains. If you don’t have enough passive income to absorb them, the losses are suspended — held in limbo until you do.

Rental real estate is passive by default. It doesn’t matter how hands-on you are, how many properties you own, or how much time you spend managing them. Unless you qualify for one of three specific exceptions, your rental losses are passive.

This matters because most rental properties generate paper losses every year. Depreciation alone — the IRS’s required deduction for building wear over 27.5 years — typically produces $5,000 to $15,000 in annual deductions on a modest property. Add mortgage interest, property taxes, insurance, maintenance, and management fees, and most rental investors show losses even when the property is operationally profitable. Under passive activity rules, those losses sit in a carryforward account, unavailable until you have passive income or sell the property.

Exception 1: the $25k allowance

Congress recognized this was harsh for small investors and created a partial exception. If your AGI is $100,000 or below and you “actively participate” in your rental, you can deduct up to $25,000 of rental losses annually against ordinary income.

Active participation is a lower standard than material participation. You don’t need to be doing the work yourself — you can use a property manager. You just need to be involved in management decisions: approving tenants, setting rents, authorizing repairs.

The allowance phases out above $100,000 AGI and disappears entirely at $150,000.

For most business owners and high-income earners, the $25k allowance has already phased out. A successful S-corp owner making $300,000 gets zero benefit from this exception. Their rental losses go into the carryforward every year until something changes.

Exception 2: Real Estate Professional status

IRC 469(c)(7) creates a broader exception for people who are genuinely in the real estate business. A Real Estate Professional is someone who:

1. Spends more than 750 hours per year in real property trades or businesses in which they materially participate, and
2. Those activities constitute more than half of their total personal services for the year.

The second test is what prevents most full-time employees from qualifying. If you work 2,000 hours at your W-2 job, you’d need to spend more than 2,000 hours in real estate to meet the majority test. That’s not realistic for most people.

But for a spouse who doesn’t work outside the home, or a business owner whose full-time occupation is real estate, REP status is achievable. And it’s powerful: qualifying as a REP takes rental activities out of the automatic passive category. Losses become non-passive if you also materially participate in the specific property.

One critical point: REP status applies to the person, not the return. On a joint return, only one spouse needs to qualify as a REP — but that spouse must personally meet both tests (hours can’t be combined between spouses for REP qualification, though they can be combined for material participation tests on individual properties).

Exception 3: the STR 7-day rule

Short-term rentals with an average stay of 7 days or fewer are excluded from the definition of “rental activity” under IRC 469(c)(2). They’re treated as business activities for passive purposes, not rental activities. This distinction matters because the passive rules that apply to business activities are different — and better.

Under the 7-day rule, whether your STR losses are passive or non-passive depends on material participation. Materially participate (typically 500+ hours/year), and losses are non-passive — deductible against any income. Don’t materially participate, and losses are passive under business activity rules, which is still preferable to traditional rental passive rules in some cases.

Most San Diego Airbnb and VRBO properties already average 3–5 night stays, meaning the 7-day rule applies automatically. The question is whether the owner can document material participation.

What happens to suspended losses

Suspended losses are not lost. They accumulate in a carryforward account attached to the specific activity (or the taxpayer, for REP-related activities). They release in two circumstances:

• Passive income: If you generate passive income from any source — another rental property that turns profitable, a limited partnership interest, passive business income — suspended losses offset that income first.
• Complete disposition: When you sell a rental property in a fully taxable transaction (not a 1031 exchange), all suspended losses attached to that property are released in the year of sale. They offset gain first, then any remaining amount is deductible against ordinary income.

A rental property sale often produces a large tax event: depreciation recapture taxed at 25%, capital gains at preferential rates, and the release of all suspended losses as ordinary deductions. These can partially offset each other, but the net result is highly dependent on how much depreciation has been taken and what the sales price is.

For investors with large suspended loss carryforwards, a strategic sale — sometimes even at a modest gain or near break-even — can release significant deductions that offset other ordinary income in the sale year.
