What Triggers a Detroit Rental Property Audit?

Understanding what triggers an IRS examination of your rental property is the foundation of smart tax planning. The IRS uses automated computer systems and statistical analysis to identify tax returns that deviate significantly from industry norms. For rental properties, this means comparing your reported expenses to your rental income across thousands of similar taxpayer profiles.

When you report rental income on Schedule E in 2026, the IRS runs your return through the Discriminant Index Function (DIF) system. This system scores returns based on specific metrics. If your score exceeds predetermined thresholds, your return gets flagged for potential examination. For rental properties, the biggest red flag is the relationship between reported income and reported deductions.

IRS Red Flags That Increase Audit Risk

• Expense-to-Income Ratio Exceeds 50%: If your deductions represent more than half your rental income, the IRS considers this statistically unusual. Most professional landlords operate with margins between 20-40%.
• Inconsistent Reporting: Varying your reported income or deductions significantly year-over-year without documented business changes signals potential problems.
• Home Office Deductions Without Business Purpose: Claiming a home office for managing rental properties triggers scrutiny unless you meet IRS’s regular and exclusive use test.
• Excessive Vehicle Expenses: Mileage deductions without proper contemporaneous records create immediate audit risk.
• Missing or Incomplete Documentation: Blank lines or missing information on Schedule E signals careless tax preparation.

Detroit-Specific Audit Considerations for 2026

Michigan’s Detroit metro area has unique audit considerations. Many Detroit properties were heavily purchased during the 2012-2015 real estate recovery, making them high-profile targets for depreciation audits. Additionally, properties in specific neighborhoods with rapid value appreciation draw additional IRS scrutiny due to potential casualty loss claim conflicts and depreciation basis disputes.

How to Prepare Audit-Ready Documentation for Rental Properties

Documentation is your strongest defense in any rental property audit. The IRS can disallow deductions if you cannot produce contemporaneous records that substantiate the expense. This doesn’t mean you need to be obsessive, but you do need to be systematic and organized.

Start by implementing a filing system that mirrors your Schedule E categories. Create folders or digital files for: mortgage interest statements, property tax receipts, insurance policies, utility bills, maintenance and repair invoices, contractor payments, property management fees, and advertising expenses for rental listings.

The Essential Documentation Checklist

• Acquisition Documents: Purchase agreement, deed, title insurance policy, and closing statement showing your basis in the property.
• Financial Records: Bank and credit card statements showing all deposits and payments related to the rental activity.
• Depreciation Worksheet: Annual depreciation calculation showing the building basis, land allocation, and applicable recovery period.
• Maintenance Records: Photographs before/after improvements, contractor invoices, receipts for materials, and work descriptions.
• Tenant Records: Lease agreements, security deposit documentation, and payment records establishing arm’s-length transactions.

Digital Organization Best Practices

Cloud storage platforms like Google Drive, Dropbox, or OneDrive allow you to organize and backup documentation systematically. Create a master folder for each rental property. Within that, create subfolders for each year and each expense category. Use consistent naming conventions: “2026-Mortgage-Interest-Statements” or “2026-Maintenance-Invoices.” This approach ensures that if the IRS requests records, you can produce them quickly and comprehensively.

What Rental Property Expenses Are Actually Deductible on Schedule E?

Not all property-related expenses are deductible on your 2026 rental property return. The IRS distinguishes between current expenses (which you deduct in the year incurred) and capital improvements (which you depreciate over time). This distinction creates significant compliance risk because misclassification can trigger audit adjustments.

Deductible Rental Expenses (2026)	Non-Deductible or Capitalized
Mortgage interest (not principal)	Principal payments on mortgage
Property taxes	Capital improvements (roof, HVAC, windows)
Insurance premiums	Personal capital items
Utilities and maintenance	Expenses for personal use portions
Repairs and maintenance	Structural renovations
Depreciation (27.5 years residential)	Land value (never depreciable)
Property management fees	Payments to related parties
Advertising (rental listings)	Political contributions

The Critical Repair vs. Capital Improvement Distinction

This is where most rental property owners get into audit trouble. A repair maintains the property’s condition. A capital improvement adds value, prolongs life, or adapts the property to a new use. If you replace a few shingles on your roof, that’s a repair (deductible). If you replace the entire roof, that’s a capital improvement (depreciable over time).

The IRS applies a facts-and-circumstances test. They look at the cost, the nature of work, the portion of the property affected, and industry practice. Expenses under $2,500 per item are often treated as repairs, though this is not a bright-line rule. Expenses over $5,000 are routinely capitalized. The gray area between creates audit risk.

What Are Passive Activity Loss Rules for 2026 Rental Income?

Passive activity loss rules are one of the most misunderstood aspects of rental property taxation. These rules prevent taxpayers from using unlimited rental property losses to offset other income like wages or investment returns. The policy goal: prevent high-income individuals from sheltering all income through aggressive real estate depreciation deductions.

Under 2026 rules, if you actively participate in managing your rental property (meaning you make management decisions and own at least 10% of the property), you can deduct up to $25,000 in passive losses annually against your active income. But this $25,000 allowance phases out if your modified adjusted gross income (MAGI) exceeds $150,000.

2026 Passive Activity Loss Phase-Out Ranges

If your MAGI is $150,000 or less and you actively participate, you can deduct the full $25,000. For every $1 of MAGI over $150,000, your deduction reduces by $0.50. By the time your MAGI reaches $200,000, your passive activity loss deduction is completely eliminated. This phase-out directly impacts your 2026 Schedule E calculations.

The Real Estate Professional Exception

If you qualify as a real estate professional under IRS standards, passive activity loss limitations don’t apply. To qualify, you must spend more than 750 hours annually in real estate activities (or more than 50% of your personal service hours in real estate), and you must materially participate in the activities. Real estate professionals in Detroit can deduct all losses without phase-out limitations.

What Are the Most Common Rental Property Audit Mistakes?

Rental property audits follow predictable patterns. IRS examiners focus on the same issues year after year because they’ve learned which areas generate adjustment revenue. Understanding these common mistakes helps you avoid them in your 2026 tax planning.

Mistake #1: Mixing Personal Use and Rental Activity

Many Detroit investors own properties that they initially used personally before converting to rental use. If you deduct expenses from the personal use period, the audit adjustment is immediate and significant. Your property must be exclusively for rental use (with rare exceptions for occasional family visits). Any personal use eliminates deductibility for that portion of expenses.

Mistake #2: Failing to Allocate Basis Between Land and Building

Land never depreciates. Only the building structure depreciates. When you purchase a rental property, you must allocate the total purchase price between land and building. Many taxpayers depreciate the entire purchase price, which is completely wrong. The IRS will deny this, and you’ll owe back taxes plus interest and penalties.

Mistake #3: Inconsistent Depreciation Calculations

Using different depreciation methods or recovery periods across years raises immediate audit flags. Residential property depreciates over 27.5 years. If you change this to 20 years without substantiation, the IRS will adjust. Maintain consistent depreciation methodology annually, and document any changes with clear business justification.

How Does Depreciation and Recapture Affect Your Rental Property Audit?

Many Detroit investors focus exclusively on depreciation benefits during ownership but fail to account for recapture when selling. This creates significant audit risk because the recapture calculation becomes another opportunity for adjustments. Depreciation recapture isn’t an audit issue directly, but miscalculating accumulated depreciation creates both ownership and sale-year audit exposure.

Understanding Depreciation Recapture Taxation

When you sell a rental property, the IRS taxes your gain in layers. First, it taxes ordinary depreciation recapture at 25%. Then, it taxes additional gain (if any) at long-term capital gains rates (0%, 15%, or 20% depending on income). This structure incentivizes accurate depreciation during ownership. If you overstated depreciation, your recapture basis is also wrong, creating further audit exposure.

Sale Scenario (2026)	Depreciation Recapture Tax
Sell after 5 years with $50,000 accumulated depreciation	25% × $50,000 = $12,500 recapture tax
Sell with $100,000 accumulated depreciation	25% × $100,000 = $25,000 recapture tax
Additional gain beyond depreciation	Long-term capital gains rates apply (0%, 15%, 20%)

 

Uncle Kam in Action: Detroit Real Estate Investor Turns Audit Risk Into $28,400 Tax Savings

Client Snapshot: Sarah, a Detroit-based real estate investor with three rental properties in the Corktown and Midtown neighborhoods, had been managing her own taxes for five years. She purchased her first property in 2019 and had added two more by 2024. Sarah’s rental income grew to $64,000 annually across the three properties, but her depreciation calculations were inconsistent, and she wasn’t properly tracking maintenance versus capital improvements.

Financial Profile: Sarah earned $85,000 annually from her W-2 employment as a project manager, plus approximately $64,000 in rental income. Her three properties had varying acquisition dates and depreciation bases, but she had never formally allocated basis between land and building. This created significant audit exposure and left substantial tax savings on the table.

The Challenge: Sarah came to Uncle Kam after receiving an IRS notice indicating her 2022 rental property return was selected for examination. The audit focused on depreciation methodology and the proper allocation between capital improvements and repairs. She realized her DIY approach had created documentation gaps that could be costly if not addressed properly. Additionally, her 2023 and 2024 returns potentially had similar issues.

The Uncle Kam Solution: We immediately implemented a comprehensive rental property audit defense strategy. First, we restructured her depreciation calculations for all three properties, properly allocating basis between land and building using Detroit property assessment records and appraisals. We then documented $18,500 in previously unrecognized depreciation deductions across the three properties for 2023-2024.

Next, we categorized all her documented expenses by property, separating capital improvements from repairs. We identified $12,300 in legitimate repairs that had been miscategorized or omitted in prior returns. Finally, we verified her passive activity loss calculations and confirmed she qualified for the full $25,000 active participant deduction for 2023-2024 (her MAGI was $149,000, just within the threshold).

The Results:

• Tax Savings: $28,400 in total tax reduction across 2022-2024 through corrected depreciation, properly classified repairs, and verified passive activity loss deductions.
• Investment: Sarah invested $3,850 in comprehensive rental property tax optimization and audit defense services.
• Return on Investment (ROI): Sarah achieved a 7.4x return on her investment in the first year. Beyond that, her proper documentation systems ensure ongoing compliance and continuous tax optimization.

This is just one example of how our proven tax strategies have helped clients achieve significant savings and audit defense simultaneously. Sarah’s story demonstrates that it’s never too late to course-correct rental property taxation. She now has defensible returns, maximized deductions, and peace of mind that her Detroit rental portfolio is properly positioned for continued growth.

Frequently Asked Questions

Can I deduct HOA fees for my rental property in 2026?

Yes, HOA fees are fully deductible as a rental property expense on 2026 Schedule E. However, you must verify that the HOA fees directly relate to the rental property and not to any personal facilities you may use. Document the HOA statements and maintain records proving the property’s rental status during the period when fees were incurred.

What happens if the IRS audits my rental property and finds errors?

IRS audit outcomes depend on error severity. Minor documentation gaps often result in simple disallowance of specific deductions with assessment of back taxes, interest (at current 2026 rates around 8-9% annually), and potential penalties (20% accuracy-related penalty for substantial underreporting). Major errors involving fraud can result in criminal referral. Always respond to IRS correspondence promptly and consider professional representation.

Can I claim a casualty loss on my Detroit rental property?

Casualty losses on rental property are deductible only if caused by sudden, unexpected events like fire, theft, or severe weather. Normal depreciation, wear and tear, or structural problems don’t qualify. You must file Form 4684 with your 2026 return and substantiate the loss with photographs, repair estimates, and insurance claim documentation. Detroit properties in flood-prone areas should monitor casualty loss opportunity annually.

How long should I keep rental property documents before discarding them?

The IRS generally has three years to audit your 2026 return, so keep all records for at least three years. However, if you have substantial underreporting (over 25% of reported income), the IRS has six years. If fraud is suspected, there’s no time limit. Conservative practice suggests keeping all rental property records indefinitely, especially depreciation schedules and acquisition documents, since these affect future sales and recapture calculations.

Is mortgage principal deductible for rental properties?

No, mortgage principal is never deductible. Only the interest portion of your mortgage payment is deductible on 2026 Schedule E. Your mortgage servicer provides a 1098 statement showing exactly how much interest you paid. This is a common audit trigger because many investors incorrectly deduct their entire mortgage payment instead of just the interest component.

What’s the difference between a rental property audit and a Schedule C audit?

Schedule E applies to passive rental activity with professional property management. Schedule C applies to active real estate business activity (including real estate professional status). IRS audit procedures differ significantly. Schedule E audits focus on depreciation and passive loss limitations. Schedule C audits examine business expense substantiation and reasonable basis allocation more broadly. If you meet real estate professional status, your 2026 reporting might shift to Schedule C with different audit implications.

Can I deduct travel expenses to manage my Detroit rental property?

Travel to manage rental property is deductible only if it directly relates to active management. A trip to Detroit to collect rent from tenants or conduct repairs qualifies. However, a vacation that includes stopping by your property doesn’t qualify. You must allocate travel expenses between deductible management time and personal time. For 2026, maintain detailed travel logs and business purpose documentation for all property-related trips.
