Passive Income and Passive Activity Loss Rules
The passive activity rules restrict how you can use passive losses to offset your taxes. Understanding them is critical for real estate investors and business owners.
Passive Income and Passive Activity Loss Rules
What Is Passive Income?
Income from activities in which you don't materially participate:
- Most rental income
- Limited partnership income
- Business income from businesses you don't work in
What Is Material Participation?
You materially participate if you meet one of these tests:
- 500+ hours per year in the activity
- Substantially all of the participation is yours
- 100+ hours AND more than any other individual
- Significant participation in multiple activities totaling 500+ hours
- Materially participated in 5 of the last 10 years
- Personal service activity: material participation in any 3 prior years
- Facts and circumstances (catch-all)
Passive Activity Loss Rules
- Passive losses can only offset passive income
- Excess losses are suspended and carried forward
- When you sell or dispose of the passive activity, all suspended losses become deductible
Rental Activity Exception
- Rental activities are generally passive regardless of participation
- Exception: If you actively participate and AGI < $100,000, deduct up to $25,000 against ordinary income (phases out to $150,000)
Real Estate Professional Exception
- If you qualify as a real estate professional, rental activities are treated as non-passive
- Requirement: More than half of personal services in real property trades, AND 750+ hours
