Understanding Rental Property Depreciation
Depreciation is a tax deduction that allows property owners to recover the cost of their rental property over time. It's not an actual cash expense, but rather an accounting method that reflects the wear and tear or obsolescence of the property. For tax purposes, the IRS allows you to deduct a portion of the property's value each year.
How it Works:
The core principle involves calculating the depreciable basis of your property and then dividing it by the applicable recovery period (useful life) set by the IRS.
- Cost Basis: This is generally the purchase price of the property, plus any costs incurred to acquire it (like legal fees, title insurance) and costs to get it ready for rental use (like renovations, repairs upon purchase).
- Land Value Exclusion: Crucially, land cannot be depreciated because it's not considered to have a limited useful life. Therefore, you must subtract the estimated value of the land from the total cost basis before calculating depreciation.
- Depreciable Basis: Cost Basis – Land Value = Depreciable Basis.
-
Recovery Period: The IRS dictates the useful life over which you can depreciate a rental property.
- For residential rental property (like apartments, houses, condos), the recovery period is 27.5 years.
- For non-residential real property (like office buildings, warehouses, retail stores), the recovery period is 39 years.
- Depreciation Method: The IRS generally mandates the straight-line depreciation method for rental properties. This means you deduct an equal amount of depreciation each year over the recovery period.
The Calculation:
Annual Depreciation = Depreciable Basis / Recovery Period (in years)
For example, if a residential rental property has a depreciable basis of $220,000 and a recovery period of 27.5 years: Annual Depreciation = $220,000 / 27.5 years = $8,000 per year.
Key Considerations:
- Placed in Service Date: Depreciation typically begins when the property is "placed in service," meaning it's ready and available for rent, not necessarily when you purchase it or when it's first occupied.
- Improvements: Significant improvements made to the property might have their own depreciation schedules.
- Mid-Month Convention: For properties placed in service or disposed of during the year, a mid-month convention often applies, meaning you only get to deduct depreciation for the portion of the year the property was in service, and it's treated as if it was placed in or taken out of service in the middle of the month. This calculator provides the full annual depreciation for simplicity.
