Your property's cost basis is the bedrock of your depreciation strategy and must be calculated accurately because it is the total amount invested in your property, serving as the required starting point for calculating all depreciation deductions according to IRS guidelines. Getting the cost basis wrong can lead to incorrect tax calculations for decades, resulting in either over- or under-depreciation.
Accuracy is critical because various factors affect the cost basis, including properly differentiating between improvements (which increase basis) and repairs (which do not). Additionally, if a property is acquired via a 1031 Exchange, precisely tracking the carryover basis is essential. Finally, since land is not depreciable, carving out an accurate land value allocation from the total cost basis prevents overstating your depreciable basis. This level of precision helps defend your tax position if ever questioned by the IRS.
Cost Basis: Definition and Factors Affecting Accuracy
- Definition: Your cost basis is the total amount invested in your property and is the starting point for calculating all depreciation.
- IRS Emphasis: The IRS Audit Technique Guidelines emphasize its accuracy for tax compliance.
- Factor 1 – Repairs vs. Additions: Misclassifying improvements (which increase cost basis) and repairs (which maintain the property and do not) leads to incorrect depreciation claims.
- Factor 2 – 1031 Exchanges: For properties acquired via an exchange, the new basis is influenced by the old property's adjusted basis, requiring precise tracking of the carryover basis.
- Factor 3 – Land Value: Since land is not depreciable, an accurate land allocation must be carved out from the total cost basis to avoid overstating the depreciable basis.
- Benefit of Accuracy: Precision ensures you get every legitimate tax benefit and helps you defend your position if questioned by the IRS.
