Let’s dive in.
How Do You Figure Depreciation on Rental Property?
Depreciation is calculated using IRS rules under the Modified Accelerated Cost Recovery System (MACRS) — the standard method for residential real estate.
Under MACRS, residential rental property depreciates over 27.5 years, while commercial property depreciates over 39 years.
The Basic Formula for Depreciation
The standard depreciation formula is:
Annual Depreciation = (Cost of Property – Land Value) / Useful Life
- Useful life:
- 27.5 years for residential rentals
- 39 years for commercial buildings
- Land cannot be depreciated
Step-by-Step: How to Calculate Depreciation Correctly
Step 1: Determine Your Property’s Cost Basis
Cost basis includes:
| Included in Cost Basis | Not Included |
|---|---|
| Purchase price (building portion) | Land value |
| Legal fees | Landscaping |
| Recording fees | Fencing added after purchase |
| Title insurance | Furniture (depreciated separately) |
| Sales tax | Appliances not included in purchase |
Step 2: Verify It’s Residential or Commercial
- Residential rental: 27.5 years
- Commercial: 39 years
If financing through a commercial property loan, depreciation rules vary slightly based on building classification.

2. Capital Improvements
These increase property value and must be depreciated:
| Improvement | Recovery Period |
|---|---|
| Roof replacement | 27.5 yrs |
| Flooring | 5–9 yrs |
| HVAC | 27.5 yrs |
| Driveway | 15 yrs |
Common IRS Mistakes to Avoid
“I depreciated the full purchase price.”
❌ Incorrect because land cannot be depreciated
“I started depreciation the year I purchased it.”
❌ IRS only allows depreciation when the property is placed in service.
“I skipped a year can I resume?”
❌ Missing years require a special IRS form to correct.
Use a Rental Property Depreciation Calculator
For investors who want automation, using a depreciation calculator saves hours of manual work.
These calculators typically handle:
- MACRS schedules
- Mid-month conventions
- Partial-year depreciation
- Improvements
- Bonus depreciation (when applicable)
Tax Benefits of Rental Property Depreciation
Depreciation is powerful because it reduces taxable rental income even when your real profit is higher.
Key Benefits
- Lowers taxable income
- Offsets rental earnings
- Improves cash flow
- Allows strategic timing of improvements
- Reduces capital gains via cost segregation
- Helps qualify for financing (especially a commercial property loan)
Example: Before & After Depreciation
Without Depreciation
| Description | Amount |
|---|---|
| Rental income | $30,000 |
| Expenses | $12,000 |
| Taxable income | $18,000 |
With Depreciation
| Description | Amount |
|---|---|
| Rental income | $30,000 |
| Expenses | $12,000 |
| Depreciation | $10,909 |
| Taxable income | $7,091 |
✔ You save taxes on $10,909 of income without spending any real money.
