Estimate how much you can save using a short-term rental (STR) tax strategy designed for high-income earners. This calculator helps you understand how the STR tax loophole, combined with cost segregation and bonus depreciation, can significantly reduce your taxable income.
Short Term Rentals CPA
Estimate potential tax savings from cost segregation and accelerated depreciation for short-term rental investors.
Answer these quick questions before reviewing the savings estimate.
Average stay less than 7 days?
This is one of the key STR classification regulations for tax purposes.
Do you materially participate?
Participation level determines whether STR losses offset ordinary/passive income.
High W-2 or business income?
High marginal tax rates get the immediate benefit from tax shelter deductions.

Learn how Short-Term Rental zoning, material participation, and cost segregation studies work under current IRS rules.
Normally, rental real estate is classified as passive by default, meaning passive losses can only offset passive income. However, IRC Section 469 contains a key exception: if the average length of customer stay on your property is 7 days or less, the property is not defined as a standard rental activity. If you materially participate, these losses are reclassified as non-passive, allowing you to use depreciation to offset active ordinary income like W-2 job salaries or business profits.
A cost segregation study is an engineering-based tax planning analysis. It identifies and reclassifies building components (such as specialized lighting, millwork, appliances, and landscaping) from 27.5-year real property to 5-year, 7-year, or 15-year personal property. This unlocks accelerated depreciation, letting you front-load up to 20% to 35% of the property's depreciable cost basis into the first tax year.
The IRS provides seven tests to prove material participation. The most common three for short-term rental investors are: (1) You spend more than 100 hours on the activity and no other individual spends more hours than you, (2) You spend more than 500 hours on the activity, or (3) Your participation in the activity constitutes substantially all of the total participation in that active business.
Straight-line depreciation spreads the building write-off evenly over 27.5 years (approx. 3.6% per year). Under a Cost Segregation Study, eligible components are accelerated using MACRS guidelines. This creates a massive first-year tax write-off which is further multiplied if bonus depreciation applies.
No. Land is non-depreciable. Under IRS rules, you must exclude the land portion from your property purchase price before calculating building and asset depreciation. This is why our calculator features a specific Land Value Allocation slider to ensure highly accurate, conservative estimates.
Tax strategy guidance for short-term rental investors and high-income taxpayers.
Engineering-based studies may help support accelerated depreciation deductions.
Serving short-term rental owners across the United States.
This calculator uses simplified assumptions to show how cost segregation may create accelerated depreciation and possible tax savings.
Land value is removed from purchase price because land is not depreciable.
Building Value = Purchase Price − Land Value
A percentage of building value is estimated as eligible for accelerated depreciation.
Accelerated Depreciation = Building Value × Cost Seg %
Accelerated depreciation is multiplied by the selected marginal tax rate.
Tax Savings ≈ Accelerated Depreciation × Tax Rate

Common questions investors ask before using STR tax planning and cost segregation strategies.
Properties with an average guest stay of 7 days or less may be evaluated differently from traditional rental activities under the passive activity rules.
A cost segregation study identifies building components that may qualify for shorter depreciation lives, which may accelerate deductions into earlier years.
Potentially, but only if the taxpayer meets the required STR and material participation rules.
Not always. Higher-value properties usually have greater potential benefit.
No. This calculator is only an educational estimate.
