Passive Activity Loss Rules (IRC 469): When Business Losses Can't Offset Other Income
Under IRC 469, losses from passive activities can only offset income from other passive activities. They cannot offset wages, active business income, or portfolio income (interest, dividends, capital gains). A passive activity is any trade or business in which the taxpayer does not “materially participate.” The most common passive activities are rental real estate and businesses where the owner is an investor, not an operator. Suspended passive losses carry forward indefinitely and are released in full when the taxpayer disposes of the entire interest in the activity in a fully taxable transaction (a sale, not a gift).
Passive vs. active income (the three income buckets):
| Income Type | Examples | Can Offset Passive Losses? |
|---|---|---|
| Active (earned) | W-2 wages, Schedule C profit (material participation), S-Corp K-1 (material participation) | No |
| Passive | Rental income, business income (no material participation), limited partnership income | Yes |
| Portfolio | Interest, dividends, capital gains | No |
Passive losses can ONLY offset passive income. They cannot cross buckets.
Material participation tests (pass ANY ONE to be active):
| Test | Requirement |
|---|---|
| 1. 500 hours | Participate 500+ hours during the year |
| 2. Substantially all | Your participation constitutes substantially all participation |
| 3. 100 hours + no one more | 100+ hours and no one else participates more |
| 4. Significant participation | 100+ hours in this activity AND 500+ total across all significant participation activities |
| 5. 5 of 10 years | Materially participated in 5 of the prior 10 years |
| 6. Personal service | Personal service activity, materially participated in any 3 prior years |
| 7. Facts and circumstances | Based on all facts and circumstances (rarely accepted by IRS) |
Most small business owners pass Test 1 (500+ hours) easily. A sole proprietor running their own business almost always materially participates. The passive activity rules primarily affect:
- Owners who invest in but don’t operate a business
- Rental real estate (passive by definition, regardless of hours)
- Limited partners (passive by statute)
- S-Corp shareholders who don’t work in the business
Rental real estate exception ($25,000):
- Active participants in rental real estate can deduct up to $25,000 of rental losses against non-passive income
- Phase-out: $1 for every $2 of modified AGI above $100,000
- Fully phased out at $150,000 of modified AGI
- “Active participation” is a lower bar than “material participation” (making management decisions, approving tenants, setting rents)
Real estate professional exception:
- 750+ hours in real estate activities AND
- More than half of personal services in real estate AND
- Material participation in each rental activity (or grouping election)
- If qualified: rental activities are NOT passive (losses offset other income, subject to the excess business loss cap)
How do passive activity losses affect small business owners?
What does material participation mean for tax purposes?
The IRS defines material participation through seven tests under Treasury Regulation 1.469-5T, and meeting any single test is sufficient. The most commonly used test is the 500-hour test: you participate in the activity for more than 500 hours during the tax year. Other tests include being the only individual who participates, participating more than 100 hours and more than any other individual, or participating in multiple activities that collectively exceed 500 hours. If you don’t materially participate, the activity’s income and losses are treated as passive, and passive losses can only offset passive income (not wages or portfolio income). Rental activities are generally treated as passive regardless of participation, with a limited $25,000 exception for active participation in rental real estate (phased out as modified AGI rises from $100,000 to $150,000).
