The Short-Term Rental Tax Strategy: How Cost Segregation Fits In

Some short-term rental losses may reduce wage or business income when the activity meets the relevant passive-activity rules. Cost segregation can change the timing of depreciation, but eligibility to use a loss requires a separate review.

How the IRS Classifies Short-Term Rentals

An average guest stay of seven days or less is one exception to the rental-activity definition for passive-loss purposes. Material participation must be established separately; more than 100 hours alone does not establish it.

Non-passive losses may reduce ordinary income, but other deduction limits can apply. Long-term rental losses generally follow passive-activity rules, subject to specific exceptions.

Where Cost Segregation Comes In

A study separates qualifying shorter-life assets from the building. The building’s recovery period depends on its use; short-term rental status alone does not establish a 27.5-year schedule. Your preparer should assess residential versus transient-use treatment as well as bonus eligibility.

Eligible assets acquired and placed in service after January 19, 2025 generally qualify for 100% bonus depreciation. Contract dates, elections, and other requirements can change the outcome.

A study identifies asset classifications. Your tax preparer determines whether and when the resulting deductions can be used. The study does not establish material participation or guarantee an income offset.

A Common Path to Non-Passive Treatment

One common route combines these two conditions; other rental exceptions may apply:

• Average guest stay of 7 days or less. This is calculated across all stays during the tax year. Calculate the actual average; a platform listing does not establish the result.
• Material participation. You must meet one of the IRS's seven material participation tests. One option is Test 3: you spend more than 100 hours on the activity during the year, and no one else spends more hours than you. Read more about the specific requirements for material participation.

How the Pieces Work Together

Review three questions separately: which assets qualify for shorter recovery periods, whether bonus depreciation applies, and whether the resulting deductions can be used. Material participation and other loss limits affect the final tax result.

A property can produce deductible expenses or losses without a cost segregation study. The study changes depreciation timing; it does not by itself establish a loss or determine whether that loss is non-passive.

100% Bonus Depreciation Is Back

Eligible assets acquired and placed in service after January 19, 2025 generally qualify for 100% bonus depreciation. Contract dates, elections, and other requirements can change the outcome.

Long-Term Rental Owners Still Benefit

Long-term rental losses generally face passive-activity limits. Real estate professional status and material participation in the rental activity must both be considered before treating those losses as non-passive.
