Why REPS matters
By default, the IRS classifies rental income and losses as “passive.” Under the passive activity rules (IRC Section 469), you can only deduct passive losses against passive income. That means even if your rental properties generate significant paper losses through depreciation, you typically can't use those losses to reduce your tax bill on your salary or business income.
REPS changes this. When you qualify, your rental activities are reclassified as non-passive. Depreciation deductions, repair expenses, and other rental losses can now directly offset your active income—subject to material participation in each rental activity.
This is especially valuable for investors who use cost segregation studies to accelerate depreciation, creating large paper losses in early years of ownership.
