Tips & Best Practices
Only the building value is depreciable — subtract the land value from your total purchase price before calculating
Keep records of all capital improvements, as these can be depreciated separately from the original building cost
Consider consulting a CPA to determine if cost segregation could accelerate your depreciation deductions
Track your accumulated depreciation to prepare for depreciation recapture tax when you sell
Frequently Asked Questions
You can use the property tax assessment to determine the ratio of land to improvements, then apply that ratio to your purchase price. For example, if the assessment shows 25% land and 75% improvements, apply those percentages to what you paid. Your CPA or a professional appraiser can also provide this breakdown.
You can only depreciate the portion of a property used for rental or business purposes. If you rent out a room in your home, you depreciate the percentage of the home dedicated to the rental. A property must be placed in service as a rental before depreciation begins.
When you sell, the IRS requires you to pay depreciation recapture tax on the total depreciation you claimed (or could have claimed) at a rate of up to 25%. This is in addition to any capital gains tax. Planning for recapture is essential when evaluating your long-term investment returns.
