The final episode of the cost segregation series. Wes covers the grouping election, the one tax election that determines whether building losses can offset practice income or get suspended indefinitely. Includes the self-rental asymmetry, how to execute the election, five pros, six cons, and when to make it.

Key Topics Covered

1. The Self-Rental Asymmetry
Rental income from a building you operate in a non-passive (taxable)
Rental losses from that same building are passive (trapped)
Result: a $300,000 year-one cost segregation loss cannot reduce your W2 or K-1; it is suspended until the building has future taxable profit

2. What the Grouping Election Does
IRC Section 1.469-4(f): elect to treat the building LLC and practice S corp as one economic unit
Losses in the building LLC that become non-passive can now offset W2 and K-1 income directly
Example: $400,000 building loss reduces $1M of practice income to $600,000, saving $150,000–$200,000 in taxes in year one

3. Qualification and Timing
Qualifies when: same ownership percentage in building and practice, dentist is the only tenant, same location
Must be elected on the original tax return for the first year of building ownership; it cannot be made retroactively
CPA must attach a disclosure statement identifying the grouped activities alongside Form 8582
 
4. Five Pros of the Grouping Election
Loss utilization: building losses offset W2 and K-1 in the year they are generated
Cost segregation amplification: first-year bonus depreciation becomes immediately usable instead of frozen
Fixes the asymmetry: losses become non-passive, matching the non-passive character of building income
Simpler participation: one shared material participation test for both activities
Predictable: no annual suspended loss ledger to manage
 
5. Six Cons of the Grouping Election
One-way door: binding in all future years; can only be undone by a material change in facts (e.g., selling the practice)
Partial sale complexity: selling the building without the practice creates complicated suspended loss treatment
Forfeits passive shelter: building losses can no longer offset passive income from outside rental properties
DSO or partner disruption: any equity sale that misaligns building and practice ownership breaks the grouping
1031 exchange complications: a grouped building is harder to roll into a like-kind exchange
Semi-retirement trap: when practice income drops, the non-passive characterization no longer helps and can hurt
 
6. Best-Case Scenario
Dentist buys practice without building, grows income into the top brackets over 5+ years, then buys the building
Commissions cost seg study in year one of building ownership, makes the grouping election, and offsets peak practice income
Worst case: buying practice and building simultaneously at low income — better to wait for a higher-income year
 
7. When to Make and When to Skip the Election
Make it when:
Buying the building with a long-term operating plan
High practice income and a cost seg study ready to deploy
No near-term plans to sell, partner, or transition ownership
 
Skip or defer when:
Income is low, preserve deductions for a higher-bracket year
You own other passive real estate and need building losses to stay passive
A DSO transaction or partnership is within the next few years
