Depreciation of doors for tax purposes involves recovering the cost of doors used in business or income-producing property over a specified period, reflecting their wear, tear, and obsolescence. The tax treatment of door depreciation depends on how the door is classified under the Internal Revenue Code and related IRS guidance.
1. Classification of Doors
a. Structural Component (Part of the Building)- Most doors, especially entry doors and interior doors that are permanently attached and integral to the building, are considered structural components of the building.- For residential rental property, such doors are treated as part of the building and are depreciated as residential rental property.- For nonresidential property, they are depreciated as nonresidential real property.
b. Personal Property- In rare cases, if a door is easily removable, not integral to the structure, and serves a specialized, non-building function, it may be classified as personal property. This could allow for a shorter recovery period, but such cases are uncommon for typical rental or business properties.
2. Depreciation Life (Recovery Period)
a. Residential Rental Property- Doors classified as part of the building are depreciated over 27.5 years using the straight-line method under MACRS (Modified Accelerated Cost Recovery System).
b. Nonresidential Real Property- Doors are depreciated over 39 years using the straight-line method under MACRS.
c. Personal Property (if applicable)- If a door qualifies as personal property (e.g., a removable interior door), it may be depreciated over 5 or 7 years, depending on its use and classification.
3. Depreciation Methods
- Straight-Line Method: This is required for real property (buildings and structural components, including most doors). The cost is spread evenly over the recovery period.
- Accelerated Methods: For personal property, accelerated methods such as 200% or 150% declining balance may be used, but this is rare for doors that are part of the building.
4. Placed in Service and Basis
- Depreciation begins when the door is placed in service (i.e., ready and available for use in the business or rental activity).
- The depreciable basis includes the cost of the door, installation, and any related expenses, reduced by any Section 179 deduction or bonus depreciation taken (if applicable).
5. Section 179 and Bonus Depreciation
- Section 179 Deduction: Generally not available for structural components of a building, including most doors, unless the door is part of qualified improvement property or certain improvements to nonresidential real property.
- Bonus Depreciation: May be available for certain qualified improvement property, but doors that are part of the building structure typically do not qualify unless they are part of a larger qualified improvement project.
6. Replacements and Adjustments
- If a door is replaced, the remaining undepreciated basis of the old door should be written off (removed from the depreciation schedule), and the new door is capitalized and depreciated over the appropriate recovery period.
- Repairs that do not materially add value or extend the useful life are generally deductible as repairs, not capitalized.
7. Recordkeeping
- Maintain records of the cost, installation, and placed-in-service date.
- Keep a depreciation schedule showing annual deductions and adjustments.

10. Practical Example
If you replace an entry door in a residential rental property for $1,000 (including installation), you would add $1,000 to the building’s basis and depreciate it over 27.5 years using the straight-line method. If you replace a removable interior door that is not integral to the structure, and it qualifies as personal property, you may depreciate it over 5 or 7 years, but this is rare.
In summary: For tax purposes, most doors in rental or business property are treated as structural components of the building and depreciated over 27.5 years (residential) or 39 years (nonresidential) using the straight-line method. Only in rare cases where a door is not integral to the building might it be depreciated over a shorter period as personal property.
