Rental Property Tax Problems: IRS Issues for Landlords and Real Estate Investors

Rental activities are generally classified as passive under IRC Section 469. Losses from passive activities can only offset other passive income — not wages or self-employment income — unless you qualify as a real estate professional or meet the $25,000 exception (for those with AGI under $100,000 who actively participate in rental management). Improper deduction of rental losses against ordinary income is a common audit trigger.

Rental property must be depreciated over 27.5 years (residential) or 39 years (commercial). If you did not claim depreciation, you may have missed significant deductions. More importantly, when you sell, the IRS recaptures depreciation at a 25% rate — even if you never claimed it. This creates surprise tax bills for landlords who sell property.

The IRS receives Form 1099-MISC and other information returns from property management companies and sometimes from tenants who pay rent through ACH. Unreported rental income is an audit trigger. Cash rent payments without documentation are particularly scrutinized.

Short-term rentals have their own complex tax rules. If average rental period is 7 days or less, the activity may be treated as a business rather than passive rental. Airbnb and VRBO issue 1099-K forms for gross receipts, which the IRS matches against your return. Proper expense documentation is critical.

If you have back taxes from unreported rental income, deductions taken incorrectly, or missed returns, the resolution process is the same as other IRS debts. The key is to file accurate amended returns first — often reducing the liability significantly — then pursue resolution. Cost segregation studies can identify additional depreciation on properties that were under-depreciated.
