Passive Activity Rules and the $25,000 Rental Allowance
| Passive Activity Rule | Description | Exception |
|---|---|---|
| General rule | Rental activities are passive; losses can only offset passive income | Active participation; real estate professional |
| $25,000 allowance | Up to $25,000 in rental losses can offset ordinary income | AGI must be under $100,000; phases out at $150,000 |
| Phase-out | $25,000 allowance phases out $1 for every $2 of AGI over $100,000 | Completely eliminated at $150,000 AGI |
| Real estate professional | All rental losses deductible if RE professional test met | 750 hours + more than 50% of work time in RE |
| Short-term rental exception | STRs with avg. stay ≤7 days are not passive per se | Subject to material participation test |

Real estate professional status: A taxpayer qualifies as a real estate professional if: (1) more than half of the personal services performed during the year are in real property trades or businesses in which the taxpayer materially participates; and (2) the taxpayer performs more than 750 hours of services in those activities. If both tests are met, the taxpayer's rental activities are not automatically passive — they are subject to the material participation tests. Practitioners should document real estate professional status carefully — the IRS frequently challenges this status.
Depreciation and Cost Segregation
| Depreciation Strategy | MACRS Life | Bonus Depreciation (2026) | Annual Deduction (Example: $500K building) |
|---|---|---|---|
| Residential rental (§1250) | 27.5 years | Not eligible for bonus | $18,182/year |
| Commercial real estate (§1250) | 39 years | Not eligible for bonus | $12,821/year |
| Land improvements (§1250) | 15 years | 20% bonus in 2026 | $47,000 first year (with bonus) |
| Personal property (§1245) | 5-7 years | 20% bonus in 2026 | Varies; significant first-year deduction |
| Cost segregation (all categories) | Varies | Accelerates into 5/7/15-year property | $50,000-$150,000+ first-year deduction |
Source: IRC §168; §1245; §1250; Rev. Proc. 87-56 (MACRS lives)
Cost segregation: A cost segregation study reclassifies components of a building from 27.5-year or 39-year property to 5-year, 7-year, or 15-year property — dramatically accelerating depreciation deductions. For a $1M rental property, a cost segregation study typically identifies $150,000-$300,000 in personal property and land improvements that can be depreciated over 5-15 years instead of 27.5-39 years. The first-year tax savings can be $30,000-$80,000.
1031 Exchange — Deferring Capital Gains on Rental Property
| 1031 Exchange Requirement | Description | Deadline |
|---|---|---|
| Like-kind property | Both properties must be real property held for investment or business use | N/A |
| 45-day identification rule | Must identify replacement property within 45 days of sale | 45 days from closing |
| 180-day exchange period | Must close on replacement property within 180 days of sale | 180 days from closing |
| Qualified intermediary | Must use a QI to hold proceeds; cannot touch the money | Before closing on relinquished property |
| Boot | Cash or non-like-kind property received is taxable | Minimize boot to maximize deferral |
| Depreciation recapture | §1250 recapture is deferred but not eliminated | Tracked in replacement property basis |

Case Study: Michael T., landlord with 8 rental properties. 2025 sale of apartment building: $1.8M proceeds; $400,000 adjusted basis; $1.4M gain ($200,000 §1250 recapture + $1.2M §1231 gain). Without 1031: $200,000 taxed at 25% = $50,000; $1.2M taxed at 20% + 3.8% NIIT = $286,800; total tax $336,800. With 1031 exchange into larger apartment complex: $0 tax; $336,800 deferred. Annual depreciation on new $2.2M property: $80,000/year. Practitioner fee: $4,500. ROI: 74.8:1.
