Property Depreciation Calculator: MACRS Deductions for Rental Properties
Calculate annual depreciation deductions for residential and commercial rental property using MACRS. Reduce your taxable rental income with accurate depreciation figures.
Depreciation is one of the most powerful tax advantages in real estate — and one of the most misunderstood. You can deduct the wear-and-tear on your rental property every year even if the property is appreciating in value. For a lot of investors, depreciation is what transforms a marginally profitable rental into a tax-efficient wealth-building vehicle.
The CalcHub Property Depreciation Calculator calculates your annual MACRS depreciation deduction for residential and commercial investment properties.
How MACRS Depreciation Works
The IRS uses the Modified Accelerated Cost Recovery System (MACRS) for depreciating real property. The key rules:
- Residential rental property: Depreciated over 27.5 years (straight-line)
- Commercial/non-residential property: Depreciated over 39 years (straight-line)
- Only the building value depreciates — not the land
- You start depreciating when the property is placed in service (available for rent)
The Land Value Problem
You can't depreciate land — so you need to separate the land value from the building value. Common methods:
- Property tax assessment ratio: Your county tax assessor often breaks out land vs. improvement values. Use the same ratio applied to your purchase price.
- Appraisal: The most accurate but costs money.
- IRS guidance: They'll accept reasonable estimates. Common splits range from 10–30% land in suburban areas, 30–50% in urban high-land-cost areas.
Example Calculation
You buy a duplex for $320,000. County assessment shows: land $64,000 (20%), improvements $256,000 (80%).
- Depreciable basis: $320,000 × 80% = $256,000
- Annual depreciation: $256,000 ÷ 27.5 = $9,309/year
Depreciation Recapture: The Catch
When you sell the property, the IRS collects "depreciation recapture" at 25% (not your regular rate) on all the depreciation you claimed. This is why long-term hold strategies and 1031 exchanges are popular — they defer or avoid recapture.
| Scenario | Tax Implication |
|---|---|
| Hold and rent indefinitely | Defer recapture; pass to heirs with stepped-up basis |
| Sell after 10 years | Pay 25% recapture on all depreciation taken |
| 1031 exchange | Defer recapture by rolling into new property |
| Sell at a loss | Recapture still applies to the extent of prior deductions |
Bonus Depreciation and Cost Segregation
For investors with larger portfolios, cost segregation studies can accelerate depreciation on certain components (appliances, carpeting, landscaping, fixtures) into 5- or 15-year classes rather than 27.5 years. Combined with bonus depreciation rules, this can generate substantial first-year deductions on a newly acquired property.
The calculator handles standard straight-line MACRS. For cost segregation analysis, you'd need a specialty CPA.
What if I convert my primary home into a rental?
Your depreciable basis is the lesser of your cost (adjusted basis) or fair market value at the time of conversion. You can't depreciate appreciation that occurred while you lived in it.
Can I deduct depreciation if I have a net loss on the rental?
Yes, but there are passive activity loss rules. If your adjusted gross income is below $100,000, you can deduct up to $25,000 in rental losses against regular income. The deduction phases out between $100K–$150K AGI. Above $150K, losses generally must be carried forward unless you're a real estate professional.
Do I have to take depreciation?
Technically you don't have to claim it — but the IRS treats it as "allowed or allowable," meaning you'll owe recapture tax when you sell as if you took it, whether you did or not. Always take it.
