Key Takeaways
- Reconstructed time logs were rejected—the IRS reduced accepted hours by 36% due to lack of contemporaneous detail.
- Missing the aggregation election forced property-by-property material participation analysis—a much harder standard.
- Total audit assessment was $19,728 (back taxes + 20% penalty + interest) on a $14,880 deduction.
- A $1,500-$3,000 tax opinion letter would have provided reasonable cause defense against the $2,976 penalty.
This case study follows an IRS audit of an investor who claimed Real Estate Professional Status while holding a full-time W-2 position. The analysis reveals the documentation failures that led to REPS disallowance, the resulting tax assessment, and the corrective measures that would have changed the outcome.
The Audit Scenario
Investor Kevin is a software engineer earning $185,000 annually. His wife Sarah manages their six rental properties (total value $1.4M). They filed jointly, claiming REPS through Sarah, deducting $62,000 in rental losses against Kevin's W-2 income, saving approximately $14,880 in federal taxes (24% bracket). The IRS selected the return for examination based on the large passive loss deduction against W-2 income. The examiner requested: Sarah's time log, evidence of material participation in each rental activity, and the rental activity aggregation election.
Audit Findings and Failures
The examination revealed three critical failures. Failure 1: Sarah's time log was reconstructed in January from calendar entries and memory—it was not contemporaneous. The log claimed 812 hours but lacked specific activity descriptions (entries read "property management—4 hours" without specifying which property or what activity). Failure 2: Sarah also worked part-time as a bookkeeper, earning $22,000 from 600 hours of work. Her total work hours were 812 (real estate) + 600 (bookkeeping) = 1,412. Real estate was 57.5% of total—above the 50% threshold. However, because the time log was reconstructed and lacked specificity, the examiner reduced the accepted real estate hours to 520 (disallowing entries without property-specific detail), dropping the percentage to 46.4%—below the 50% threshold. Failure 3: No aggregation election was filed. Without aggregation, Sarah needed to show material participation in each of the six properties individually—impossible given the reduced hour count.
Outcome and Corrective Lessons
The examiner disallowed REPS, reclassified the $62,000 rental loss as passive (suspended), and assessed $14,880 in additional tax plus $2,976 in accuracy-related penalty (20%) plus $1,872 in interest. Total assessment: $19,728. The losses were suspended, available to offset future passive income or release upon property sale. Corrective measures that would have prevented this outcome: (1) Sarah should have logged hours contemporaneously with specific property addresses and detailed activity descriptions—her actual hours likely exceeded 750 but the documentation was inadequate. (2) The aggregation election should have been filed with the original return. (3) Sarah should have ensured the time log was detailed enough to withstand skeptical review. (4) Given the $14,880 annual tax benefit, investing $1,500-$3,000 in a tax attorney opinion letter would have provided reasonable cause defense against the penalty.

Common Pitfalls
Reconstructing REPS time logs at tax preparation time rather than logging hours throughout the year
Risk: The IRS regularly discounts or entirely disallows reconstructed logs, reducing accepted hours below the 750-hour threshold
Use a weekly logging system—spreadsheet, app, or paper log—with date, property address, activity description, and hours for each entry
Assuming the CPA will file the aggregation election without being specifically instructed
Risk: Many CPAs are unfamiliar with the aggregation election; without it, REPS must be demonstrated for each property individually
Explicitly discuss the aggregation election with your CPA before the first REPS return is filed and verify it is attached
Not obtaining a tax opinion letter for REPS claims with annual tax savings exceeding $10,000
Risk: Without a reasonable cause defense, the 20% accuracy-related penalty is nearly automatic when REPS is disallowed
Invest $1,500-$3,000 in a written tax opinion from a qualified tax attorney documenting the factual and legal basis for the REPS claim
