When claiming depreciation for doors on business tax returns, several common mistakes can arise, often due to misclassification, incorrect recovery periods, or improper allocation of costs. Below is a detailed analysis of the most frequent errors, supported by the relevant legal framework and IRS guidance:
1. Misclassification of Doors as Personal Property (§ 1245) Instead of Real Property (§ 1250)
Legal Framework:- Under the Internal Revenue Code, doors are generally considered part of the building’s structural components and thus are classified as § 1250 property (real property), not § 1245 property (personal property).- Treas. Reg. § 1.48-1(e)(2) specifically lists doors as structural components of a building.
Common Mistake:- Taxpayers sometimes incorrectly classify doors (including interior, exterior, overhead, and fire doors) as tangible personal property (§ 1245) to claim a shorter recovery period (e.g., 5 or 7 years) and accelerated depreciation methods (e.g., 200% declining balance), rather than the correct 27.5-year (residential rental) or 39-year (nonresidential) straight-line depreciation for real property.
Correct Treatment:- Doors that are part of the building envelope or interior partitions are almost always § 1250 property and must be depreciated as part of the building over the appropriate recovery period (27.5 or 39 years under GDS).
2. Incorrect Recovery Periods and Depreciation Methods
Legal Framework:- The recovery period for nonresidential real property (including doors) is 39 years under GDS and 40 years under ADS; for residential rental property, it is 27.5 years under GDS and 30 or 40 years under ADS.- The straight-line method is required for real property.
Common Mistake:- Using a shorter recovery period (e.g., 5 or 7 years) or an accelerated method (e.g., 200% or 150% declining balance) for doors, which is only appropriate for tangible personal property, not for structural components of a building.
Correct Treatment:- Depreciate doors as part of the building using the straight-line method over the correct recovery period (27.5 or 39 years, depending on property type).
3. Improper Allocation of Costs in Cost Segregation Studies
Legal Framework:- Cost segregation studies must properly classify and allocate costs between § 1245 and § 1250 property.- The IRS Cost Segregation Audit Technique Guide and industry-specific matrices (e.g., for retail, restaurant, auto dealership, residential rental) consistently classify doors as part of the building, except for certain special lightweight doors (e.g., Eliason doors in restaurants) that may be § 1245 property if they are not permanent and are readily removable.
Common Mistake:- Over-allocating costs to § 1245 property by including standard doors, which should be classified as § 1250 property, in the personal property category to accelerate depreciation.
Correct Treatment:- Only doors that are not permanent, are readily removable, and are not integral to the building’s structure (such as certain double-action or flexible doors in high-traffic areas) may be classified as § 1245 property. All other doors must be treated as part of the building.
4. Failing to Capitalize Door Replacements as Improvements
Legal Framework:- Under the tangible property regulations, replacing an entire door (especially if it is a major component or substantial structural part) is generally a capital improvement and must be depreciated over the building’s recovery period.
Common Mistake:- Deducting the full cost of door replacements as a repair expense rather than capitalizing and depreciating as an improvement.
Correct Treatment:- Capitalize the cost of door replacements that improve, restore, or adapt the property to a new or different use, and depreciate over the appropriate recovery period.
5. Failing to Maintain Adequate Records
Legal Framework:- Taxpayers must maintain records substantiating the cost, classification, and placed-in-service date of depreciable property, including doors.
Common Mistake:- Inadequate documentation of the cost of doors, their installation, or their classification, leading to disallowed deductions or adjustments on audit.
Correct Treatment:- Maintain invoices, contracts, and cost segregation reports that clearly identify the nature and use of each door and support its classification and depreciation method.
6. Improper Use of Section 179 or Bonus Depreciation
Legal Framework:- Section 179 and bonus depreciation are generally not available for structural components of a building, including most doors.
Common Mistake:- Claiming Section 179 or bonus depreciation on doors that are part of the building’s structure.
Correct Treatment:- Only claim Section 179 or bonus depreciation on doors if they are classified as tangible personal property and not as structural components, which is rare.
7. Summary Table: Correct Classification and Depreciation of Doors
8. Key Takeaways
- Most doors are structural components and must be depreciated as part of the building over 27.5 or 39 years using the straight-line method.
- Only certain non-permanent, readily removable doors may qualify as tangible personal property for shorter recovery periods.
- Misclassification, incorrect recovery periods, and improper use of Section 179/bonus depreciation are common errors.
- Proper documentation and adherence to IRS guidance and industry-specific matrices are essential to avoid audit issues.
